Ultimate Setup Guide for Cryptocurrency Mining with Linux ...

Got tired of having to occasionally manually update ElvUI and didn't feel like using their client, so I wrote my own (kinda)!

oh god I didn't know what flair to use so I hope Tech Support's okay

Windows Release: https://github.com/VladiMatt/ElvUI-Downloadereleases/tag/v1

Source code (.py) available here: https://github.com/VladiMatt/ElvUI-Downloader

(please don't laugh at my spaghetti I know it's ugly but it works and my friend who works at Oracle says that means it's good enough to ship)

No Mac or Linux support for the moment. Might maybe look into supporting them at some point if anybody really wants it, but I don't have a machine running either OS so I wouldn't be able to test it myself.
Over the past few days I taught myself Python by slapping together a downloader for ElvUI that automates the entire download/installation process. I spent more time making this than I will ever save from not having to download/install it manually anymore, so I decided to open-source it and post it here so others can maybe benefit from the time that I wasted!

Features:

So long as the TukUI team doesn't change the download page, or change the naming convention for either file, or send me a cease and desist, this should continue to work forever!
If I continue to update this I'd like to add a GUI of some sort so it at least looks nice. Perhaps with faction themed skins for you to look at for the 6 seconds the program's open.
Lastly, as stated at the top of the post, I don't have the means to really add proper Mac/Linux support for the moment as I can't easily test any changes, but if someone wants to fork this and add it themselves then go for it!
EDIT: 10 hours after posting I remembered to set the repo to public. My brain is nice and smooth today. Anyway in the comments some other (better) programs have been shared so you should probably use those instead but I'm still proud of my garbage so I'm keeping the post up.

Windows / Linux Guide to using Trezor with Bitcoin Core (HWI)

This is a guide to using your Trezor with Bitcoin Core. It may seem like more trouble than it's worth but many applications use Bitcoin Core as a wallet such as LND, EPS, and JoinMarket. Learning how to integrate your Trezor into a Bitcoin Core install is rather useful in many unexpected ways. I did this all through the QT interfaces, but it's simple to script. There is a much simpler guide available from the HWI github, and the smallest Linux TLDR is here
Unfortunately, I don't have access to a Coldcard or Ledger. I'm not sure how the setpin or -stdinpass parameters are handled on that HW.

( A ) Install TrezorCTL, HWI, and build GUI

You only need to set the wallet up once, but may repeat to upgrade

( A.I ) Download extract and install HWI

  1. Download and isntall Python
  2. Download https://github.com/bitcoin-core/HWI/archive/1.1.2.zip
  3. Extract it to a working folder (assumes C:\User\Reddit\src\HWI)
  4. Change Directory (cd) to working folder cd "C:\User\Reddit\src\HWI"
  5. Setup venv python -m venv .venv
  6. Enter venv .venv\Scripts\activate.bat 1
  7. Install dependencies python -m pip install -U setuptools pip wheel
  8. Install TrezorCTL python -m pip install trezor[hidapi]
  9. Install HWI python -m pip install hwi pyside2
  10. Download github.com/libusb/libusb/releases/download/v1.0.23/libusb-1.0.23.7z
  11. Extract MS64\dll\libusb-1.0.dll from the archive
  12. Copy to pywin copy libusb-1.0.dll .venv\Lib\site-packages\pywin32_system32\

( A.II ) Build the QT UI files

  1. Download and install MSYS2
  2. Launch a mingw64.exe shell
  3. CD to working folder cd "C:\User\Reddit\src\HWI"
  4. Enter venv source .venv/Scripts/activate 1
  5. Run UI build bash contrib/generate-ui.sh

( B ) Create a Trezor wallet in Bitcoin Core (testnet)

You only need to set the wallet up once, no private key data is stored, only xpub data

( B.I ) Retrieve keypool from HWI-QT

  1. Launch hwi-qt.exe --testnet (assuming testnet)
  2. Click Set passphrase (if needed) to cache your passphrase then click Refresh
  3. Select you trezor from the list then click Set Pin (if needed)
  4. Ensure your Trezor in the dropdown has a fingerprint
  5. Select Change keypool options and choose P2WPKH
  6. Copy all the text from the Keypool textbox

( B.II ) Create the wallet in Bitcoin QT

  1. Launch Bitcoin Core (testnet) (non-pruned) 2
  2. Select Console from the Window menu
  3. Create a wallet createwallet "hwi" true
  4. Ensure that hwi is selected in the console wallet dropdown
  5. Verify walletname using the getwalletinfo command
  6. Import keypool importmulti '' (note ' caging)
  7. Rescan if TXNs are missing rescanblockchain 3

( C.I ) Grab Tesnet coins

  1. Select the Receive tab in Bitcoin Core (testnet)
  2. Ensure that the Wallet dropdown has hwi selected
  3. Select Create new receiving address and copy address
  4. Google "bitcoin testnet faucet" and visit a few sites
  5. Answer captcha and input your addressed copied from C.I.3

( D ) Spending funds with HWI

This is how you can spend funds in your Trezor using Bitcoin Core (testnet)

( D.I ) Create an unsigned PSBT

  1. Select the Send tab in Bitcoin Core (testnet)
  2. Ensure that the Wallet dropdown has hwi selected
  3. Verify your balance in Watch-only balance
  4. Rescan if balance is wrong (see B.II.7) 3
  5. Craft your TXN as usual, then click Create Unsigned
  6. Copy the PSBT to your clipboard when prompted

( D.II ) Sign your PSBT

  1. In HWI-QT click Sign PSBT
  2. Paste what you copied in D.I.6 in PSBT to Sign field
  3. Click Sign PSBT
  4. Copy the text for PSBT Result

( D.III ) Broadcast your TXN

  1. Select the Console window in Bitcoin Core (testnet)
  2. Ensure that the Wallet dropdown has hwi selected
  3. Finalize PSBT: finalizepsbt
  4. Copy the signed TXN hex from the hex field returned
  5. Broadcast TXN: sendrawtransaction

Final Thoughts

I did this all through the GUI interfaces for the benefit of the Windows users. Windows console is fine, but the quote escaping in windows console is nightmarish. Powershell would be good, but that throws this on a whole another level for most Windows folks.
There is also the need to use HWI-QT due to a bug in blank passphrases on the commandline. You can work around it by toggling passphrase off or on, but again, it's more than I wanted to spell out.
Footnotes:
  • 1. - Later version of python put the activate script under 'bin' instead of 'Script'
  • 2. - You can run pruned, but you need to have a fresh wallet
  • 3. - Rescan is automatic on 'importmulti' but I was pruned so it was wierd

Raspibolt troubles: bitcoind shutting down, out of space?

Hey y'all. Had my node running for some 19-20 months now. Following the Stadicus guide. on a raspberry pi 3. Bitcoin v0.19.0.1
the other day I just checked up on it and noticed it was in a failed state and didn't have the HDD mounted. The log seems to indicate it just stopped, the last entry is
2020-08-21T17:35:41Z socket recv error Connection reset by peer (104) 
I did the troubleshooting guide (no stranger to this) figuring there had been a power outage possibly. I ran fsck and it took a LONG while to find and clean up a lot of errors. The drive works fine, i can connect to it via my pc (using linux file systems paragon) transfer files.. etc. I ran fsck another time or two to be sure and no errors found. It's got 57% free space.
I got the raspberry pi to mount the HDD again, started up bitcoind and it started to sync slowly. I'd check with getblockchain info and figured it would take around 60+ hours to finish and left it overnight.
Today I come back to find it was no longer syncing. Now no matter what I do, starting bitcoind manually, or having it automatically boot getblockchain info gives me an error
error: Could not connect to the server 127.0.0.1:8332 Make sure the bitcoind server is running and that you are connecting to the correct RPC port. 
So bitcoind seems to shutdown instantly after starting it. AND checking the log, the last message from the 21st (above) is all that's there, no new information in the log.
I tried to re-install bitcoin v0.19.0.1 and got a suspect. When extracting the package into the tmp folder, it fails due to out of space errors. So this possibly means something is going on with the SD card? or something filled it up? Not sure what to check, or how really.
curiously the startup script for the raspibolt displays this for the SSD. Not sure how to interpret that. 36M free?
 SSD 36M (240%) 
here i'm stuck, what can I try next? I believe I have backups of the important information. I'd like to avoid a total reformatting if at all possible.

How much space left on your local HDD after fresh mynode install - 1TB HD

My machine is linux mint 19.x running virtualbox and nothing else installed. I am at blockheight 573369 running mynode version 0.2.09 and my local disk has 186GB of space left. My virtualbox VM folder inside my home directory has taken up 704GB of space?! I dont understand whats going on here. The bitcoin blockchain itself today is ~270GB. My fresh and minimal install of linux mint combined with this i would expect not to use anymore than ~350GB total for the entire VM but something seems off. I have tried to blow away and reinstall virtualbox/mynode and this keeps happening. Yes, I have turned off and deleted the snapshot function in linux mint as well. The only folder on the entire system that is using up so much space is the Virtualbox VMs folder inside my home directory. Any help would be appreciated!

A Beginners Guide To Setting Up A Full Node On Your PC

Hello there, I thought I would write a quick guide on setting up a full node on your PC as I've seen a lot of posts about full nodes around recently.

What is a full node?

From Bitcoin Wiki: "Any computer that connects to the Bitcoin network is called a node. Nodes that fully verify all of the rules of Bitcoin are called full nodes."
Full nodes are essential for keeping Bitcoin in the hands of the people (decentralised). If you want to accept payments in Bitcoin it is also recommended for security reasons that you use your own full node. For more info on full nodes, click me.

Hardware Requirements:

Bitcoin nodes can be run on worse specs, but it is recommended that you have the following specification when running a full node on your PC:

Getting Set Up:

Once the blockchain is downloaded and verified you are the official owner of a Bitcoin full node! It's that easy! This guide was intended to be simple and easy to follow. For more in-depth instructions and troubleshooting advice feel free to leave a comment or visit https://bitcoin.org/en/full-node#what-is-a-full-node.
Hope that helped :)

BTC Node. Need help with Ubuntu and BTC core program. To the Linux experts here in reddit.

The good thing of loosing a post, is that you have to retype everything and this means that you are able to shorten the post.
So. TLDR, I have 2 hdd, 80gb and 320, the second one has only, all the Blockchain info, from another already running node. I am not able to tell BTC Core program that the files are already there so he does not need to download 300gb. After hours of Google and linux forums, I am stuck in this issue. Every time I type "bitcoin-qt" on my terminal, it shows as a first download. Any help will be appreciate.

Full story.
English is not my first language, and this is being typed for second time (please have mercy on my grammar or misspelling mistakes), because I posted the question on linux subreddit nobody give a f..... so I decided to bring it here, posted a short post with the link and the automatic bot deleted because the of the link. I erased both the linux and the bitcoin post, and made a third one new, here, with plain text, copy pasting the info from the linux post. Never appeared on the "new" section of this sub. So hours of typing lost, and here we are.
Old Notebook. 80gb drive, and noob to Linux. Although I have some pc and logic knowledge, installed MINT due to a recommendation from a Bitcoin community, but since I have a friend with an already running node, with Ubuntu switched to this one, just to have the same system.
Once Ubuntu installed, on the 80gb and pc running, I copy and pasted the whole bitcoin folder from my friends pc to my 320 gb. Up to here all was good. But here is the problem

My friend, who does not understand nothing about linux, is owner of a company and has an IT guy who made everything for him, but would not be willing to help me a lot, (just to be good with his boss but right now it is not reachable for me), but when we where on my pc he told me that Linux is very sensitive to ports, in other words, a small usb change, will do a program to loose the path for the files. SO, instead of using the 320gb disk on USB i installed on this notebook second Hdd bay (its an old high end laptop with 2 sata connectors), he was able to set the program and everything went well for a couple of hours, Bitcoin Core program started synchronizing, downloading very little info.

I needed to turn of the pc to move it, so closed the program (waited until bitcoin core program told me was safe to) and turn it off, then turn it on again, and the problem was there, bitcoin core program started trying to download the whole blockchain in the spare 2gb of the 320 gb disk.
So what it seemed to happen is that even when the disk is installed on a sata bay from the motherboard, as I did not installed ubunutu with this disk connected it's route (adress?) is dinamyc and that is why BTC Core Program lost the files and does not recognize it.
After hours of google, linux forums and "askubuntu" i was able to, mount the 320gb disk, first editing the fstab ( i followed the guide in "askubuntu.com/questions/125257/how-do-i-add-an-additional-hard-drive") by the way. Trying to use VIM editor was a pain, it is REALLY difficult to type something there, and save it without pressing a wrong key. I had to cancel and start over at least a dozen times (plus reading several guides), but still was not able to mount the disk (Actually after following the steps, the hdd (320) disappeared from the GUI). went back, erased, and the did the NANO steps, and I THINK that now the hard drive it is fixed (before, any change,when restarting the second hdd took some time to appear, now it seems that is mounted and to a fixed adress). Well, after mounting the hdd, I tryed to call the bitcoin-qt and the initial download page appear and again tries to download from the initial block. I searched over hours "file association in ubuntu", "program files path" etc etc and the only thing I found is how to set up the desired software to open a file.

For you to understand my mess, when I did the "user:user" thing, I did not understand completely what I was doing, (yes I had to be in sudo) BUT i think I managed to did the correct thing as both hdd are shown in the Ubuntu GUI.

Some additional data is
Both hard drives are formated in Ext4
I have (I think that) a fstab.bak before any changes

I knwo that linux users sometimes ask for details on the system, just tell me the commands and i can run them to stick any info needed.

Thanks for the help in advance.

Am I Operating on a Virtual Machine? Would that even be possible for someone to set up without my knowledge? Am I Crazy?

Long story short, I am friends with a programmer. He has had access to 2 of our computer's, and we've even done some minor work for him before to help him with a large project. He's a MS Enterprise user and I'm pretty sure he uses Azure in his business. He even helped us by using his card to buy us a Windows key when all we had was cash.
We've started to notice weird stuff like BIOS boot devices that appeared and disappeared shortly after we discovered them (Windows ToGo & a Linux device) & seems to post twice when booting. Suddenly we have unaccounted for differences in network traffic between the Resource Manager (logs a 1000kb+ spike) & the Task Manager(doesn't log this 1000kb+ spike). "Mouse Intercept" files in game folders. We can't make changes or disable some services we would be able to change before. Internal SATA configured as external SATA. NFC & Payments services, Hyper V & Azure services we didn't install. Unspecified TCP connections and loopbacks, & when we run traceroute the first hop is always " * ".
Today we tried to reinstall Windows again (we've done this fresh and re-flashed the BIOS many times) and it said there was only 16mb of space left on a 300GB hard drive even though we only had League of Legends and a browser installed.
TL;DR Is it possible that our friend has us thinking we have control, but we're really using virtual machines while he allocated our resources to himself for some reason (Bitcoin mining? Maybe?). Have we been hacked? Can we hack our way out? It's been a year of research and we've turned up nothing useful. I feel crazy.

AMA/Tutorial: Run a full node on AWS free tier with local LAN storage

AMA/Tutorial: Run a full node on AWS free tier with local LAN storage
This is a tutorial/AMA on how you can be running a full node, in the AWS cloud, for very low cost or even free.
I used to run a node on my local network but there is a problem with this; your public IP is broadcast, and then it gets associated with Bitcoin. Node owners are likely to own Bitcoin, and this raises your personal threat profile, validated against my IDS/IPS logs.
Run a VPN? Many VPNs are automatically blocked, or sketchy. Tor is also blocked on a large portion of the internet. Neither provide you with a real static IP, and that helps out the network.
There is a easy solution to this; run a node on the AWS free tier, and use an elastic IP so you have a static address. Bandwidth is free in, and low cost out, and you can control how much of that you use easily, and control your spent. The problem is that Amazon charges a LOT for online storage and even with a 1MB blocksize, the blockchain is very large and growing steadily! We mitigate this by using a VPN back to your network, where you can store the blockchain on a SMB share.
It is not complicated to do, but there are very many moving pieces to keep track of and configure. In order to fully trust your node, the best way is to build it from scratch. This is my goal in walking you through the process.
There are lots of ways to accomplish this same task; I only want to present one that works, and you can go from there. Once you have access to the blockchain in the cloud for reasonable prices, you can also look at things like the Lightning Network.
This article makes four major assumptions:

  1. That you have a OpenVPN server on your network and know how to configure it. I use pfSense and OpenVPN; others will work just as well, but you'll need to do a little work to figure out the particulars. If you don't know how, do not fret! There are loads of good tutorials for just about every platform. Or ask below. I also limited the user with access to the share at the firewall specifically to the IP hosting the share to lower the threat envelope.
  2. That you have the blockchain downloaded locally and reasonably up to date. If you don't, head on over to bitcoin.org and download it for OSX or Windows or Linux, whatever you use for your workstation. Follow the directions to set up the software and download/synchronize it to the network. This will take awhile! Once you've synchronized, copy the data directory to your SMB share you want the AWS instance to access. You could also synchronize everything directly on AWS too, but it will likely take longer and may cost a bit for the bandwidth.
  3. That you're on windows. OSX and Linux will have slightly different processes to connect to the instance via the terminal and SSH. If you need help, ask, and I am sure we can get you fixed up.
  4. That you've read the excellent bitcoin.org full node tutorial here: https://bitcoin.org/en/full-node

With that, on with the show!
First: Head on over to https://aws.amazon.com/ and make yourself an account.
Once you've set up you'll need to start the process of creating a virtual machine on AWS. Look for this graphic and click on it:

Start by launching a new machine

Follow the rabbit hole, and you'll be looking to create a plain jane Amazon AMI Linux instance. It looks like this:

Pick the basic AMI instance
Keep in mind you want to pick the x86 version, which is the default.

Continue clicking, you'll want to select the t2.micro instance that is eligible for the free tier for new accounts.

Pick the free tier. You can also upgrade to the smaller tier for more ram, but the micro works for now.
Now, you're going to need a way to connect to your soon-to-be-created node in the cloud. Amazon uses SSH keys to do this, so the next step means you're going to make some. You need to save this file, as if you lose it, you won't be able to access your node anymore. Much like your wallet private keys!

Beware losing your keys!

If you've made it this far, you're almost launched!
Now we need to convert the key to a format that we can use to connect to the instance from Windows. I recommend using Putty! https://www.putty.org/ if you don't have it already; if you're on OSX or Linux, you likely have what you need already.
Follow the guide here to get connected: https://docs.aws.amazon.com/AWSEC2/latest/UserGuide/putty.html

Next you'll need to set up a opening in the firewall if you want incoming connections. This is done by adding to the security group in the "Network and Security" section; edit it to look like this:

Change the inbound security rules for the instance to accept incoming connections on 8333.

The hard part is over!
Optional: Configuring a static IP. Amazon calls their implementation "elastic" IPs, but it's really a static IP that you can move around between instances very easily. It will ensure your public address on AWS does not change; it isn't required, but it is better if you intend on allowing outgoing connections.
Go back to the main dashboard display.
In "Network and Security", click on "Elastic IPs".
Select Allocate New Address (blue button on top) and then select it in the table. In actions, you will see "Associate Address". Select this then assign the address to the instance you have previously configured. Done!

Next up: Log into your machine, and immediately update everything. Use the IP provided by Amazon, or the Elastic IP if you assigned one to the instance in the last step.
type: "sudo yum update"

Now, let's get the VPN configured.
First step is to install OpenVPN. We need to install the extended package library to do this.
type: "sudo amazon-linux-extras install epel"
type: "sudo yum-config-manager --enable epel"
Now you can install OpenVPN.
type: "sudo yum install openvpn"
You will need your credential file from OpenVPN; it's a file you generate that will have a .ovpn extension. But you're going to need to upload it to the instance. You can do this through the scp command on OSX or Linux, but if you're on Windows, you'll need another utility. Get WinSCP here: https://winscp.net/eng/download.php
But we'll have to tell it where your key file is so you can login. Select "New Session", then use the same IP and username as you did to connect before. We'll need to tell it about the key file though! Select the "Advanced" tab then under the SSH section, click on "Authentication" and then select your private key file you generated in the tutorial above.
Connect and upload the .ovpn file that you generated when you added a user for the VPN. This step depends on your OpenVPN configuration - ask below if you have problems.
Next, let's verify we can connect to the VPN!
type: "openvpn --config my-configuration-file-made-by-openvpn.ovpn &"
You will be prompted for a password if you configured one.
Verify operation by pinging your LAN router, e.g.
type: "ping 192.168.2.1" or the address of the SMB server where you shared the information.

Allllrighty! Next up is getting connected to your blockchain. Create a directory where the data directory will be mounted.
type: "mkdir blockchain"
We need to install samba and some utilities to get things mounted.
type: "sudo yum install samba"
type: "sudo yum install cifs-utils"

Now let's mount the folder:
type: "sudo mount -t cifs //192.168.2.100/Bitcoin ./blockchain -o user=bitcoin,vers=2.0,uid=ec2-user,gid=ec2 user,file_mode=0777,dir_mode=0777"
Where " //192.168.2.100/Bitcoin" is the address of the SMB server and share where you put the data directory from your initial sync. If you didn't, and just want to sync everything from AWS, then make sure it's a folder where your user has access. In this case, I'm assuming you've made a SMB user with the name "Bitcoin". The command will prompt you for the password to access the share. The other bits ensure you can have read and write access to the share once it's mounted in AWS.

Now we're ready for some Bitcoin! Props to the tutorial here: https://hackernoon.com/a-complete-beginners-guide-to-installing-a-bitcoin-full-node-on-linux-2018-edition-cb8e384479ea
But I'll summarize for you:
Download and then re-upload with WinSCP, or download directly to your instance with wget, the most current Bitcoin core. In this case, it's bitcoin-0.18.0-i686-pc-linux-gnu.tar.gz downloaded from https://bitcoin.org/en/bitcoin-core/.
Let's verify it hasn't been tampered with once you have it uploaded to the terminal:
type: "sha256sum bitcoin-0.18.0-i686-pc-linux-gnu.tar.gz"
Then compare that with the hash value that's listed in the SHA256SUMS.asc file on bitcoin.org. In this case, "36ce9ffb375f6ee280df5a86e61038e3c475ab9dee34f6f89ea82b65a264183b" all matches up, so we know nobody has done anything evil or nefarious to the file.
Unzip the file:
type: "tar zxvf bitcoin-0.18.0-i686-pc-linux-gnu.tar.gz"
There is a warning about a symbolic link; everything seems to work OK regardless, but if anyone knows what or how to fix, please comment.
We'll need to get some missing libraries before we can run it; these aren't in the basic AMI instance.
type: "sudo yum install glibc.i686"
type: "yum install libgcc_s.so.1"

FINALLY! We are ready to launch the program. Go to the "bin" directory inside where you unzipped the Bitcoin Core tarball. (e.g. /home/ec2-useblockchain/bitcoin-0.18.0/bin)
./bitcoind -datadir=/home/ec2-useblockchain/data
You will see the program either start to sync and download, or start to read the existing blockchain file that you put in the share from before.

Congrats!

There are a couple extra steps to have it automatically start on reboot, but let's see if anyone gets this far first. I use the "screen" program to do this, but there's also a daemon mode, and some other functionality that is discussed in the hackernoon tutorial.
The primary cost will be outgoing bandwidth. AWS charges $0.10/GB beyond 15GB; You can limit the outgoing bandwidth easily according to your budget: https://bitcoin.org/en/full-node#reduce-traffic

Hope this encourages people to try running a free, or very low cost, cloud node, with a substantially reduced threat profile.

Looking back 18 months.

I was going through old emails today and came across this one I sent out to family on January 4, 2018. It was a reflection on the 2017 crypto bull market and where I saw it heading, as well as some general advice on crypto, investment, and being safe about how you handle yourself in cryptoland.
I feel that we are on the cusp of a new bull market right now, so I thought that I would put this out for at least a few people to see *before* the next bull run, not after. While the details have changed, I don't see a thing in this email that I fundamentally wouldn't say again, although I'd also probably insist that people get a Yubikey and use that for all 2FA where it is supported.
Happy reading, and sorry for some of the formatting weirdness -- I cleaned it up pretty well from the original email formatting, but I love lists and indents and Reddit has limitations... :-/
Also, don't laught at my token picks from January 2018! It was a long time ago and (luckliy) I took my own advice about moving a bunch into USD shortly after I sent this. I didn't hit the top, and I came back in too early in the summer of 2018, but I got lucky in many respects.
----------------------------------------------------------------------- Jan-4, 2018
Hey all!
I woke up this morning to ETH at a solid $1000 and decided to put some thoughts together on what I think crypto has done and what I think it will do. *******, if you could share this to your kids I’d appreciate it -- I don’t have e-mail addresses, and it’s a bit unwieldy for FB Messenger… Hopefully they’ll at least find it thought-provoking. If not, they can use it as further evidence that I’m a nutjob. 😉
Some history before I head into the future.
I first mined some BTC in 2011 or 2012 (Can’t remember exactly, but it was around the Christmas holidays when I started because I had time off from work to get it set up and running.) I kept it up through the start of summer in 2012, but stopped because it made my PC run hot and as it was no longer winter, ********** didn’t appreciate the sound of the fans blowing that hot air into the room any more. I’ve always said that the first BTC I mined was at $1, but looking back at it now, that’s not true – It was around $2. Here’s a link to BTC price history.
In the summer of 2013 I got a new PC and moved my programs and files over before scrapping the old one. I hadn’t touched my BTC mining folder for a year then, and I didn’t even think about salvaging those wallet files. They are now gone forever, including the 9-10BTC that were in them. While I can intellectually justify the loss, it was sloppy and underlines a key thing about cryptocurrency that I believe will limit its widespread adoption by the general public until it is addressed and solved: In cryptoland, you are your own bank, and if you lose your password or account number, there is no person or organization that can help you reset it so that you can get access back. Your money is gone forever.
On April 12, 2014 I bought my first BTC through Coinbase. BTC had spiked to $1000 and been in the news, at least in Japan. This made me remember my old wallet and freak out for a couple of months trying to find it and reclaim the coins. I then FOMO’d (Fear Of Missing Out”) and bought $100 worth of BTC. I was actually very lucky in my timing and bought at around $430. Even so, except for a brief 50% swing up almost immediately afterwards that made me check prices 5 times a day, BTC fell below my purchase price by the end of September and I didn’t get back to even until the end of 2015.
In May 2015 I bought my first ETH at around $1. I sent some guy on bitcointalk ~$100 worth of BTC and he sent me 100 ETH – all on trust because the amounts were small and this was a small group of people. BTC was down in the $250 range at that point, so I had lost 30-40% of my initial investment. This was of the $100 invested, so not that much in real terms, but huge in percentages. It also meant that I had to buy another $100 of BTC on Coinbase to send to this guy. A few months after I purchased my ETH, BTC had doubled and ETH had gone down to $0.50, halving the value of my ETH holdings. I was even on the first BTC purchase finally, but was now down 50% on the ETH I had bought.
The good news was that this made me start to look at things more seriously. Where I had skimmed white papers and gotten a superficial understanding of the technology before FOMO’ing, I started to act as an investor, not a speculator. Let me define how I see those two different types of activity:
So what has been my experience as an investor? After sitting out the rest of 2015 because I needed to understand the market better, I bought into ETH quite heavily, with my initial big purchases being in March-April of 2016. Those purchases were in the $11-$14 range. ETH, of course, dropped immediately to under $10, then came back and bounced around my purchase range for a while until December of 2016, when I purchased a lot more at around $8.
I also purchased my first ICO in August of 2016, HEAT. I bought 25ETH worth. Those tokens are now worth about half of their ICO price, so about 12.5ETH or $12500 instead of the $25000 they would be worth if I had just kept ETH. There are some other things with HEAT that mean I’ve done quite a bit better than those numbers would suggest, but the fact is that the single best thing I could have done is to hold ETH and not spend the effort/time/cost of working with HEAT. That holds true for about every top-25 token on the market when compared to ETH. It certainly holds true for the many, many tokens I tried to trade in Q1-Q2 of 2017. In almost every single case I would have done better and slept better had I just held ETH instead of trying to be smarter than Mr. Market.
But, I made money on all of them except one because the crypto market went up more in USD terms than any individual coin went down in ETH or BTC terms. This underlines something that I read somewhere and that I take to heart: A rising market makes everyone seem like a genius. A monkey throwing darts at a list of the top 100 cryptocurrencies last year would have doubled his money. Here’s a chart from September that shows 2017 year-to-date returns for the top 10 cryptocurrencies, and all of them went up a *lot* more between then and December. A monkey throwing darts at this list there would have quintupled his money.
When evaluating performance, then, you have to beat the monkey, and preferably you should try to beat a Wall Street monkey. I couldn’t, so I stopped trying around July 2017. My benchmark was the BLX, a DAA (Digital Asset Array – think fund like a Fidelity fund) created by ICONOMI. I wasn’t even close to beating the BLX returns, so I did several things.
  1. I went from holding about 25 different tokens to holding 10 now. More on that in a bit.
  2. I used those funds to buy ETH and BLX. ETH has done crazy-good since then and BLX has beaten BTC handily, although it hasn’t done as well as ETH.
  3. I used some of those funds to set up an arbitrage operation.
The arbitrage operation is why I kept the 11 tokens that I have now. All but a couple are used in an ETH/token pair for arbitrage, and each one of them except for one special case is part of BLX. Why did I do that? I did that because ICONOMI did a better job of picking long-term holds than I did, and in arbitrage the only speculative thing you must do is pick the pairs to trade. My pairs are (No particular order):
I also hold PLU, PLBT, and ART. These two are multi-year holds for me. I have not purchased BTC once since my initial $200, except for a few cases where BTC was the only way to go to/from an altcoin that didn’t trade against ETH yet. Right now I hold about the same 0.3BTC that I held after my first $100 purchase, so I don’t really count it.
Looking forward to this year, I am positioning myself as follows:
Looking at my notes, I have two other things that I wanted to work into this email that I didn’t get to, so here they are:
  1. Just like with free apps and other software, if you are getting something of value and you didn’t pay anything for it, you need to ask why this is. With apps, the phrase is “If you didn’t pay for the product, you are the product”, and this works for things such as pump groups, tips, and even technical analysis. Here’s how I see it.
    1. People don’t give tips on stocks or crypto that they don’t already own that stock or token. Why would they, since if they convince anyone to buy it, the price only goes up as a result, making it more expensive for them to buy in? Sure, you will have friends and family that may do this, but people in a crypto club, your local cryptocurrency meetup, or online are generally not your friends. They are there to make money, and if they can get you to help them make money, they will do it. Pump groups are the worst of these, and no matter how enticing it may look, stay as far away as possible from these scams. I even go so far as to report them when I see them advertise on FB or Twitter, because they are violating the terms of use.
    2. Technical analysis (TA) is something that has been argued about for longer than I’ve been alive, but I think that it falls into the same boat. In short, TA argues that there are patterns in trading that can be read and acted upon to signal when one must buy or sell. It has been used forever in the stock and foreign exchange markets, and people use it in crypto as well. Let’s break down these assumptions a bit.
i. First, if crypto were like the stock or forex markets we’d all be happy with 5-7% gains per year rather than easily seeing that in a day. For TA to work the same way in crypto as it does in stocks and foreign exchange, the signals would have to be *much* stronger and faster-reacting than they work in the traditional market, but people use them in exactly the same way.
ii. Another area where crypto is very different than the stock and forex markets centers around market efficiency theory. This theory says that markets are efficient and that the price reflects all the available information at any given time. This is why gold in New York is similar in price to gold in London or Shanghai, and why arbitrage margins are easily <0.1% in those markets compared to cryptoland where I can easily get 10x that. Crypto simply has too much speculation and not enough professional traders in it yet to operate as an efficient market. That fundamentally changes the way that the market behaves and should make any TA patterns from traditional markets irrelevant in crypto.
iii. There are services, both free and paid that claim to put out signals based on TA for when one should buy and sell. If you think for even a second that they are not front-running (Placing orders ahead of yours to profit.) you and the other people using the service, you’re naïve.
iv. Likewise, if you don’t think that there are people that have but together computerized systems to get ahead of people doing manual TA, you’re naïve. The guys that I have programming my arbitrage bots have offered to build me a TA bot and set up a service to sell signals once our position is taken. I said no, but I am sure that they will do it themselves or sell that to someone else. Basically they look at TA as a tip machine where when a certain pattern is seen, people act on that “tip”. They use software to see that “tip” faster and take a position on it so that when slower participants come in they either have to sell lower or buy higher than the TA bot did. Remember, if you are getting a tip for free, you’re the product. In TA I see a system when people are all acting on free preset “tips” and getting played by the more sophisticated market participants. Again, you have to beat that Wall Street monkey.
  1. If you still don’t agree that TA is bogus, think about it this way: If TA was real, Wall Street would have figured it out decades ago and we would have TA funds that would be beating the market. We don’t.
  2. If you still don’t agree that TA is bogus and that its real and well, proven, then you must think that all smart traders use them. Now follow that logic forward and think about what would happen if every smart trader pushing big money followed TA. The signals would only last for a split second and would then be overwhelmed by people acting on them, making them impossible to leverage. This is essentially what the efficient market theory postulates for all information, including TA.
OK, the one last item. Read this weekly newsletter – You can sign up at the bottom. It is free, so they’re selling something, right? 😉 From what I can tell, though, Evan is a straight-up guy who posts links and almost zero editorial comments.
Happy 2018.

Java spring testcase and arhitectural questions

So I I've been a paid developer for past 3 years. I have now acquired quite much programming knowledge. All from devops, frontend, backend, automation, linux, windows... I can do almost any job at an entry level and pick it up quickly. A half a year ago I changed my job to fulltime java spring developer. Also I am self-taught programmer or I'd rather say self-learned. I didn't study programming much but I got by because I am quite a quick learner and I am attracted to complex stuff so I am learning by doing new things.
But a few months ago I decided I want to specalize in java spring backend development. Mainly I want to become as proficent as possible in writting quality, well tested and well maintable code for web applications.
I have been developing an application in my free time. I want to properly implement custom exceptions, tests and laters ci/cd pipeline. So below is my 1st of my many questions to come.
Lets say app is arhitectured so it has
when testing service methods. Can I use service methods for preparing for tests? or should I relly on other components(in this example repository)
In the case bellow: when running raffleService.newRaffle();a new raffle is created and stored into database. when calling raffleService.stopRaffle(id) raffle is stopped
In this test scenario I am testing whether raffle has already finished. Is this sufficient? or should I manually change raffle in database? (using raffleRepository)
java @Test public void whenFinishRaffleTest_RaffleAlreadyRunningException() { Exception exception = assertThrows(RaffleStillRunningException.class, () -> { // prepare Raffle raffle = raffleService.newRaffle(); Long raffleID = raffle.getRaffleID(); raffle = raffleService.stopRaffle(raffleID); // when raffleService.stopRaffle(raffleID); }); String expectedMessage = "Raffle has already finished!"; String actualMessage = exception.getMessage(); assertTrue(actualMessage.contains(expectedMessage)); }
Few other questions I'd have are:
I am building a simple backend for loterry application using bitcoin lightning. I plan on opensourcing it when I am finished and I am hoping I'll receive as much constructive feedback as possible

(Updated) [Staking] Reddcoin Core client GUI wallet on a Raspberry Pi Model 3B

Intro

This thread is an update to my first Reddcoin staking tutorial that was written 7 months ago.
 
The reason for the update
My Reddcoin Core software crashed and became unusable. My Raspberry Pi 3B would lag and freeze, I couldn't stake anymore.
 
Instead of just redoing everything the same way, I wanted to see if I could improve on 3 points:
 
The updates
 
If you would like to tip me
Writing a tutorial like this takes time and effort; tips are appreciated. My Reddcoin address: RqvdnNX5MTam855Y2Vudv7yVgtXdcYaQAW.

This video shows how long it takes to start Reddcoin Core.   TL;DR:
     

Extra

Backup
Backup your wallet to prevent losing the RDDs in your wallet! There are two methods to backup, do both. Make new backups if you create a new receiving address!
 
 
   
Boot with only 1 USB drive plugged in:
Make sure only the USB drive (with the swap partition and data partition) is plugged in when you boot up your Raspberry Pi. This to make sure the swap partition (/dev/sda1) is recognized correctly.   If you boot up with multiple USB drives, Lubuntu might see the USB drive with the swap partition as the second drive (instead of the first drive), and ignore the 2 GB swap partition. If this happens, starting Reddcoin can render the Raspberry Pi unresponsive.
   
Connection issues If you have issues syncing the blockchain because you have 0 network connections, please follow the instructions in this thread.
   
Start Reddcoin Core easier
Run a shell script (.sh file), so you can start Reddcoin just by double clicking on an icon on your Desktop.
   
Minimization options
Adjust minimization options, so you can safely press on the X button (the close/exit button on the upper right corner).
   
RealVNC VNC Viewer (client) and VNC Connect (server): To remote connect to the Raspberry Pi, I use VNC Viewer ad VNC Connect from RealVNC.
 
   
Chromium as browser: The updates break Firefox, the browser crashes when you try to run it. Install another browser, Chromium, to solve this issue.
   
Updates / Upgrades
If Software Updater shows up and tells you that there is updated software available, do not install the updates using Software Updater. Use LXTerminal to update Lubuntu.

My growing collection of info about NEO

It can be very time consuming to keep up to date on a single blockchain project let alone multiple ones. If you just heard about NEO a few weeks ago it would be impossible catch up on past occurrences due to high volume of Reddit posts and articles made on the project. I’m going to try and simplify the past, present and future as much as I can into one well thought-out post. I hope I can be helpful to anyone who has been investigating like myself. I will include sources with all of my research.

Key notes from the White Paper http://docs.neo.org/en-us/
Digital Assets
Digital assets are programmable assets that exist in the form of electronic data. With blockchain technology, the digitization of assets can be decentralized, trustful, traceable, highly transparent, and free of intermediaries. On the NEO blockchain, users are able to register, trade, and circulate multiple types of assets. Proving the connection between digital and physical assets is possible through digital identity. Assets registered through a validated digital identity are protected by law.
Digital Identity
Digital identity refers to the identity information of individuals, organizations, and other entities that exist in electronic form. The more mature digital identity system is based on the PKI (Public Key Infrastructure) X.509 standard. In NEO, we will implement a set of X.509 compatible digital identity standards. This set of digital identity standards, in addition to compatible X.509 level certificate issuance model, will also support Web Of Trust point-to-point certificate issuance model. Our verification of identity when issuing or using digital identities includes the use of facial features, fingerprint, voice, SMS and other multi-factor authentication methods.
Smart Contracts
The NeoContract smart contract system is the biggest feature of the seamless integration of the existing developer ecosystem. Developers do not need to learn a new programming language but use C#, Java and other mainstream programming languages in their familiar IDE environments (Visual Studio, Eclipse, etc.) for smart contract development, debugging and compilation. NEO's Universal Lightweight Virtual Machine, NeoVM, has the advantages of high certainty, high concurrency, and high scalability. The NeoContract smart contract system will allow millions of developers around the world to quickly carry out the development of smart contracts.
Economic Model
NEO has two native tokens, NEOand NeoGas NEO represents the right to manage the network. Management rights include voting for bookkeeping, NEO network parameter changes, and so on. The minimum unit of NEO is 1 and tokens cannot be subdivided. GAS is the fuel token for the realization of NEO network resource control. The NEO network charges for the operation and storage of tokens and smart contracts, thereby creating economic incentives for bookkeepers and preventing the abuse of resources. The minimum unit of GAS is 0.00000001.
Distribution Mechanism
NEO's 100 million tokens are divided into two portions. The first portion is 50 million tokens distributed proportionally to supporters of NEO during the crowdfunding. This portion has been distributed.
The second portion is 50 million NEO managed by the NEO Council to support NEO's long-term development, operation and maintenance and ecosystem. The NEO in this portion has a lockout period of 1 year and is unlocked only after October 16, 2017. This portion WILL NOT enter the exchanges and is only for long-term support of NEO projects. The plans for it are as below:
▪ 10 million tokens (10% total) will be used to motivate NEO developers and members of the NEO Council
▪ 10 million tokens (10% total) will be used to motivate developers in the NEO ecosystem
▪ 15 million tokens (15% total) will be used to cross-invest in other block-chain projects, which are owned by the NEO Council and are used only for NEO projects
▪ 15 million (15% total) will be retained as contingency
▪ The annual use of NEO in principle shall NOT exceed 15 million tokens
GAS distribution
GAS is generated with each new block. The initial total amount of GAS is zero. With the increasing rate of new block generation, the total limit of 100 million GAS will be achieved in about 22 years. The interval between each block is about 15-20 seconds, and 2 million blocks are generated in about one year. According to this release curve, 16% of the GAS will be created in the first year, 52% of the GAS will be created in the first four years, and 80% of the GAS will be created in the first 12 years. GAS will be distributed proportionally in accordance with the NEO holding ratio, recorded in the corresponding addresses. NEO holders can initiate a claim transaction at any time and claim these GAS tokens at their holding addresses.
Consensus mechanism: dBFT
The dBFT is called the Delegated Byzantine Fault Tolerant, a Byzantine fault-tolerant consensus mechanism that enables large-scale participation in consensus through proxy voting. The holder of the NEO token can, by voting, pick the bookkeeper it supports. The selected group of bookkeepers, through BFT algorithm, reach a consensus and generate new blocks. Voting in the NEO network continues in real time, rather than in accordance with a fixed term.
Cross-chain assets exchange agreement
NeoX has been extended on existing double-stranded atomic assets exchange protocols to allow multiple participants to exchange assets across different chains and to ensure that all steps in the entire transaction process succeed or fail together. In order to achieve this function, we need to use NeoContract function to create a contract account for each participant. If other blockchains are not compatible with NeoContract, they can be compatible with NeoX as long as they can provide simple smart contract functionality.
Cross-chain distributed transaction protocol
Cross-chain distributed transactions mean that multiple steps of a transaction are scattered across different blockchains and that the consistency of the entire transaction is ensured. This is an extension of cross-chain assets exchange, extending the behavior of assets exchange into arbitrary behavior. In layman's terms, NeoX makes it possible for cross-chain smart contracts where a smart contract can perform different parts on multiple chains, either succeeding or reverting as a whole. This gives excellent possibilities for cross-chain collaborations and we are exploring cross-chain smart contract application scenarios.
Distributed Storage Protocol: NeoFS
NeoFS is a distributed storage protocol that utilizes Distributed Hash Table technology. NeoFS indexes the data through file content (Hash) rather than file path (URI). Large files will be divided into fixed-size data blocks that are distributed and stored in many different nodes
Anti-quantum cryptography mechanism: NeoQS
The emergence of quantum computers poses a major challenge to RSA and ECC-based cryptographic mechanisms. Quantum computers can solve the large number of decomposition problems (which RSA relies on) and the elliptic curve discrete logarithm (which ECC relies on) in a very short time. NeoQS (Quantum Safe) is a lattice-based cryptographic mechanism. At present, quantum computers do not have the ability to quickly solve the Shortest Vector Problem (SVP) and the Closest Vector Problem (CVP), which is considered to be the most reliable algorithm for resisting quantum computers.
Reasons for choosing dBFT over PoW and PoS:
With the phenomenal success of Bitcoin and its increasing mainstream adoption, the project’s unbounded appetite for energy grew accordingly. Today, the average Bitcoin transaction costs as much energy as powering 3.67 average American homes, which amounts to about 3000 times more than a comparable Credit Card settlement.
This mind boggling amount of energy is not, as it is commonly believed, being wasted. It is put to good use: securing the Bitcoin network and rendering attacks on it infeasible. However, the cost of this security mechanism and its implications for an increasingly warming and resource hungry planet led almost the entire crypto industry to the understanding that an alternative has to be found, at least if we’re interested in seeing blockchain technology gaining overwhelming mainstream adoption.
The most popular alternative to PoW, used by most alternative cryptocurrency systems, is called Proof-of-Stake, or PoS. PoS is highly promising in the sense that it doesn’t require blockchain nodes to perform arduous, and otherwise useless, cryptographic tasks in order to render potential attacks costly and infeasible. Hence, this algorithm cuts the power requirements of PoS blockchains down to sane and manageable amounts, allowing them to be more scalable without guzzling up the planet's energy reserves.
As the name suggests, instead of requiring proof of cryptographic work, PoS requires blockchain nodes to proof stake in the currency itself. This means that in order for a blockchain node to be eligible for a verification reward, the node has to hold a certain amount of currency in the wallet associated with it. This way, in order to execute an attack, a malevolent node would have to acquire the majority of the existing coin supply, rendering attacks not only costly but also meaningless, since the attackers would primarily harm themselves.
PoS, as well as PoW, simply cause the blockchain to fork into two alternative versions if for some reason consensus breaks. In fact, most blockchains fork most of the time, only to converge back to a single source of truth a short while afterwards.
By many crypto enthusiasts, this obvious bug is very often regarded as a feature, allowing several versions of the truth to survive and compete for public adoption until a resolution is generated. This sounds nice in theory, but if we want to see blockchain technology seriously disrupt and/or augment the financial sector, this ever lurking possibility of the blockchain splitting into two alternative versions cannot be tolerated.
Furthermore, even the fastest PoS blockchains out there can accomodate a few hundred transactions per second, compare that to Visa’s 56,000 tx/s and the need for an alternative becomes clear as day.
A blockchain securing global stock markets does not have the privilege to fork into two alternative versions and just sit and wait it out until the market (or what’s left of it) declares a winner. What belongs to whom should be engraved in an immutable record, functioning as a single source of truth with no glitches permitted.
After investigating and studying the crypto industry and blockchain technologies for several years, we came to the conclusion that the delegated Byzantine Fault Tolerance alternative (or dBFT) is best suited for such a system. It provides swift transaction verification times, de-incentivises most attack vectors and upholds a single blockchain version with no risk of forks or alternative blockchain records emerging - regardless of how much computing power, or coins an attacker possesses.
The term Byzantine Fault Tolerance (BFT) derives its name from the Byzantine Generals problem in Game Theory and Computer Science, describing the problematic nature of achieving consensus in a distributed system with suboptimal communication between agents which do not necessarily trust each other.
The BFT algorithm arranges the relationship between blockchain nodes in such a way that the network becomes as good as resilient to the Byzantine Generals problem, and allows the system to remain consensus even if some nodes bare malicious intentions or simply malfunction.
To achieve this, Antshare’s version of the delegated BFT (or dBFT) algorithm acknowledges two kinds of players in the blockchain space: professional node operators, called bookkeeping nodes, who run nodes as a source of income, and users who are interested in accessing blockchain advantages. Theoretically, this differentiation does not exist in PoW and most PoS environments, practically, however, most Bitcoin users do not operate miners, which are mostly located in specialized venues run by professionals. At Antshares we understand the importance of this naturally occurring division of labor and use it to provide better security for our blockchain platform.
Accordingly, block verification is achieved through a consensus game held between specialized bookkeeping nodes, which are appointed by ordinary nodes through a form of delegated voting process. In every verification round one of the bookkeeping nodes is pseudo-randomly appointed to broadcast its version of the blockchain to the rest of the network. If ⅔ of the remaining nodes agree with this version, consensus is secured and the blockchain marches on. If less than ⅔ of the network agrees, a different node is appointed to broadcast its version of the truth to the rest of the system, and so forth until consensus is established.
In this way, successful system attacks are almost impossible to execute unless the overwhelming majority of the network is interested in committing financial suicide. Additionally, the system is fork proof, and at every given moment only one version of the truth exists. Without complicated cryptographic puzzles to solve, nodes operate much faster and are able to compete with centralized transaction methods.

OnChain
It is important to note the technical difference between Onchain and NEO. Onchain is a private VC-backed company with over 40 employees. NEO is a public platform with different community-led groups contributing to this public project. There exists NEO council comprised of the original NEO creators, employees from Onchain, full time NEO council members and there is also the first Western based group called City of Zion. This confusion is likely the source of the rumour about Antshares and Alibaba having a connection. Onchain and NEO are separate entities who are intimately related via cross-chain communications and similar designs.
Onchain, a Shanghai-based blockchain R&D company, first started developing Antshares in February of 2014 which will eventually become the foundation of DNA. Onchain was founded by CEO Da HongFei and CTO Erik Zhang in response to the attention from private companies garnered by the development of Antshares, China’s first public blockchain. In contrast to the weeks-old start-ups launching ICOs that is happening currently in the blockchain world, it took them 22 long months of R&D to even begin providing services to their first customers. Finally, in April 2016, the first whitepaper on consensus protocol from China was born — the dBFT (delegated Byzantine Fault Tolerance) protocol.
2016 was a busy year for Onchain and they really picked up the pace that year. Other than continuing the development of Antshares, brushing shoulders with Fortune 500 companies, Onchain became the first Chinese blockchain company to join Hyperledger — an open source blockchain project started by the Linux Foundation specifically focusing on the development of private and consortium chains for businesses. It is here where the Da HongFei and Erik Zhang, entered the hyperbolic time chamber that is now known as Fabric, a platform by Hyperledger for distributed ledger solutions, and has consequently helped them to develop many aspects underpinning the design of DNA.
In June of 2016, during the first of many future partnerships with Microsoft China, Onchain founded Legal Chain specifically targeting the inadequacies of the digital applications within the legal system. In 2005, (Digital Signature Act) was passed into national law which permitted an effective digital signatures to gain the same legal rights as a real signature.
In company with Microsoft China, they are also aiming to integrate the technology with Microsoft’s face and voice recognition API function to kick start this digital revolution within the legal system. At the same time, a partnership was formed with FaDaDa, a third-party platform for electronic contracts that has processed over 27 million contracts to date, to provide secure evidence storage with DNA. If that’s not enough, they were also voted as KPMG’s top 50 Fintech Company in China and established a relationship with the Japanese Ministry of Economy, Trade and Industry which led to the recent tour to Japan. Finally, at the end of 2016 they announced a partnership with Alibaba to provide attested email service for Ali Cloud with Legal Chain where it provides a proof-of-existence for a blockchain-powered email evidence repository for enterprise-level use.
Fosun Group, China’s largest private conglomerate, have recently invested into Onchain in order to apply DNA across all of its businesses. Currently, Fosun International has a market cap of 102.98 billion dollars on the Hong Kong Stock Exchange and that is only its international branch.
The role of Onchain so far is reminiscent of Ethereum’s EEA in addition to a stronger emphasis of governmental cooperation. Onchain has identified the shortcomings of present laser focus of hype on public platforms such as NEO and Ethereum and addressing that with DNA. DNA envisions a future where a network of assorted, specifically designed blockchains serving private enterprises, consortiums, government and the public communicating with each other forming an interconnected blockchain network.
This is the goal of DNA — infiltrating every little inefficient niche that had no better alternatives before the invention of blockchain. What is especially critical to remember during this explosive time of hype driven partly by the obscene degree of greed is that not every little niche that blockchain can fill will be holding its own little ICO for you to “go to the moon on your rocket powered lambos”. Some of those efficiencies gained will simply be consumed by companies privately or by public systems such as the legal system.

Networks proves itself with the first ICO
ICOs, on other platforms such as Ethereum, often resulted in a sluggish network and transaction delays. While NEO’s dBFT consensus algorithm is designed to achieve consensus with higher efficency and greater network throughputt, no amount of theoretical calculations can simulate the reality of real-life conditions.
--Key Observations--
Smart Contract Invocations:
A total of 13,966 smart contracts invocations were executed on the NEO network over this time period, of which, nearly all called the RPX smart contract method mintTokens. A total of 543,348,500 RPX tokens were successfully minted and transferred to user accounts, totalling 10,097 smart contract executions.
Refunded Invocations:
A total of 4182 refund events were triggered by the smart contract method mintTokens. (Note: RPX has stated that these refunds will be processed within the next two weeks.)
Crowdsale statistics:
A successful mintTokens execution used around 1043 VM operations, while an execution that resulted in a refund used 809 VM operations. Within the hour and six minutes that the token sale was active, a total of 12,296,409 VM operations were executed. A total of 9,575 unique addresses participated in the RPX ICO. Half of these, approximately 4,800 unique addresses, participated through CoZ’s Neon wallet. The top 3 blocks with the most transactions were block 1445025 (3,242 transactions), block 1444902 (2,951 transactions), and block 1444903 (1609 transactions).
Final Thoughts
At the moment, the consensus nodes for the NEO network are operated by the NEO Council in China. By Q1 2018, NEO Council aims to control less than two-thirds of the consensus nodes.
We are pleased to note that the NEO network continuted to operate efficiently with minimal network impact, even under extreme network events. Block generation time initially slowed down to 3 minutes to process the largest block, but quickly recovered to approximately 25 seconds. Throughout the entire RPX ICO, consensus nodes were able to achieve consensus and propagate new block transactions to the rest of the network. In closing, while we consider this performance to be excellent, NEO Council and City of Zion areworking closely together on upgrades, that will increase the throughputs of the NEO network.

WARNING: Clipboard MITM attack on Windows in the wild

TLDR: Windows malware intercepts a BTC address copied to the clipboard so that the pasted address is different, diverting funds to the attackers wallet which has 8.8 BTC of transactions. It mangles an XMR address. Visually inspect every transaction destination address before clicking OK!
Update: source for the malware found: a win32diskimager.exe downloaded from download.cnet.com, of all places, with a total of 4,500 downloads. More in the update at the bottom of the post.
Update 3: u/gugap and colleagues posted a detailed analysis here: https://www.welivesecurity.com/2018/03/14/stealing-bitcoin-download-com/
And great news that the file has been removed from CNET!
Original post:
I was setting up xmr-stak on my Windows desktop as the Linux version requires compiling which I'm not comfortable with. I was getting invalid address errors from the pool with two different wallet addresses, and I knew one of them is a good address with certainty having done transactions with it in the past.
After further head-scratching I noticed that the XMR address I copy from my password manager to the config file differs from the one that's pasted! I didn't notice it as the beginning and end characters are the same; the substitution is in the middle. The substitution can be defeated easily by copy-pasting the address in two chunks. But it does substitute the incorrect address even when the address is part of a longer string, such as the entire config file.
The fact that it generates invalid addresses (every time?) made me suspect this attack is meant for some other coin, most likely Bitcoin. I tested with a few BTC and BCH addresses, and it indeed generates the same address every time (below). Possibly the XMR attack is a by-product for the hack searching for BTC address strings, and it spits out an address without destination when confronted with an XMR address. [edit: After doing some further checks, the malware seems to look for the first "1" in the address and substitutes it with his BTC address below. I just learned that (one type of) BTC address always starts with a "1", which confirms the theory.]
While I believe this only allows the attacker to divert BTC funds to his address and doesn't compromise my XMR wallet or private keys, I already created a new wallet on my Linux machine, and moved my funds there. Now I'm considering doing this for all my coins as who knows what other monsters lurk behind the SSDs...
I thought I run a pretty tight ship with my desktop and cryptos, and do most of my computing in Linux. I only install wallets linked from the official websites, and verify checksums. I had heard of such attacks before, and always double-check the pasted address when moving funds. Fortunately I didn't lose any money as I noticed this while setting up XMR mining.
Somehow this got to my computer, and I have to deal with it and tighten my controls. Now, is there a secure way to clean my computer, or should I re-install Windows completely?
Below sample outputs for XMR and BTC addresses:
Correct XMR address generated with moneroaddress.org, copied in two chunks: 466mBJsXq4k8n4aampbico1Mn3muVyiBJUpfmq4oGjmrMCP1ZuXCz69HfuHDpsT1BQZKqdp2CV3QV5nUEsqSg1ygegLmqRygj Incorrect address when copy-pasting in one go, substitutions in bold, the address is different for each XMR address: 466mBJsXq4k8n4aampbico1BQZKqdp2CV3QV5nUEsqSg1ygegLmqRygjHDpsT1BQZKqdp2CV3QV5nUEsqSg1ygegLmqRygj
Another correct XMR address: 41BQZKqdp2CV3QV5nUEsqSg1ygegLmqRygjbRErDcCVrMLtZ5u1BQZKqdp2CV3QV5nUEsqSg1ygegLmqRygjiMQcTg
Incorrect address which differs from the previous one: YmNRSAn6JQP7jNuWYieZEx1BQZKqdp2CV3QV5nUEsqSg1ygegLmqRygj Correct Bitcoin address: 1GfyupfMmoNn9w9f9S7NQ6ouL1cgZW8MvM
Turns into this incorrect Bitcoin address, same address every time (at the time of writing it has 230 transactions worth 8.8 BTC). This BTC address is in the substitution in the XMR address above in bold. 1BQZKqdp2CV3QV5nUEsqSg1ygegLmqRygj
ALWAYS visually check that the address you send to is actually the one you copied. Don't just skip past the withdrawal confirmation page on your exchange; double-check that it is identical to the one you intend to send funds to.
Update:
Many have asked about the potential source. I know it's not an email as I don't use POP, and don't open attachments. Likely attack vectors are web ads, PDFs, or some crypto software I've installed recently. Haven't found the source, though.
For cleaning, F-Prot didn't find anything, Malwarebytes found the following and I quarantined them. After resetting twice my clipboard copies a Bitcoin address correctly. I will still re-install Windows completely just to be safe.

Update 2:
Thanks to u/gugap I found the source for the infection!
Step-by-step. I was doing a backup of one of my Raspbian installs a few weeks back, and downloaded Win32 Disk Imager from download.cnet.com: http://download.cnet.com/s/win32-disk-image
I uploaded the file to VirusTotal, and got a scary list of suspicious items VirusTotal found in the file:
CAT-QuickHeal Trojan.IGENERIC Cylance
Endgame malicious (high confidence) ESET-NOD32
Fortinet MSIL/ClipBanker.DF!tr McAfee
McAfee-GW-Edition Artemis Sophos AV
TrendMicro-HouseCall Suspicious_GEN.F47V0119 VBA32
Seems like we found the source for McAfee's wealth j/k. Here the full report: https://www.virustotal.com/#/file/7b3d52200895d02bee51fc03217088a383158494dcac5f570dd875cdd1f2f248/detection
F-Secure didn't recognize anything then or today. I downloaded again just now, and it's infected. I reran it through Malwarebytes as well and it doesn't detect malware, either, only after the payload has been delivered.
Thanks again to u/gugap and others for helping find the source! Given the source is a CNET site I had less reason to suspect it, so I don't feel like a total idiot.
On the other hand, it's pretty scary that 4,500 (!) people have downloaded that file in the past two years (!!), over three hundred in the past week alone! I reported the file to CNET.
Also, it is very difficult to avoid such malware if AV doesn't detect it, and it's coming from a legit site. Time to ditch Windows for good, and start using airgapped TAILS for working with private keys.

[03:05] what's up peeps [03:05] ahaha [03:05] haha [03:05] how long has this been going on? [03:05] I'm not familiar with this one [03:06] its been there for a while [03:06] it's been here since the end of october [03:06] we just need to get it cleaned up a bit and put it up for download [03:06] but yeah, we have a link on our homepage [03:07] http://www.gnu.org/software/bzip2/download [03:07] the .tar.gz we downloaded from that site earlier [03:07] that was just an archive of the compressed file [03:07] it doesn't include the header of the compressed file [03:07] that is something we could fix up [03:07] so, here is where you download it [03:07] http://www.gnu.org/software/emacs/download.html [03:07] thanks, that should do it for now [03:07] you can go there [03:07] yeah, i'll be waiting for the update to finish [03:08] alright, well, let me know when it's finished [03:08] it'll take a while for the last bits to download, so you can just put the .el file in the directory you extracted it to [03:08] i'm on linux now and it worked [03:08] sorry, i guess i've never had linux experience before [03:08] oh well, sorry, i thought i was good at it :P [03:08] well, i've never had anything else before, so i'm still learning [03:08] i think the way i did it is pretty similar to the way it works for windows in terms of setting up a shortcut to the folder, then you just hit the key combination, and the folder's contents are automatically copied to that shortcut [03:08] so there's not as much need for that special shortcut [03:08] but you can do that with a command line tool if you want to :P [03:08] anyway, nice find [03:08] it looks like I will be stuck with my $200 for a little while... [03:08] so, if you're interested, you can send me some coins :D [03:08] well, thanks [03:09] i'm definitely going to do that [03:09] i don't have a lot of time now though [03:10] but i have to go to my computer tomorrow, so i will be back for the start of the discussion [03:11] well, no worries [03:11] i look forward to it! [03:11] thanks for inviting me! [03:11] i'd be happy to answer questions you have [03:11] I'm not sure how far off i am, though [03:12] if i can help, I will [03:12] what's the link to the newbie thread? [03:12] is it the one with that big edit [03:13] I was wondering if you could answer one thing for me [03:13] what are you planning on doing? [03:13] for the moment i'm going to try and write another episode [03:14] what about it? [03:14] but it's not the greatest, i've been working on another thing [03:14] ok [03:14] are you working on a new album? [03:15] yes [03:15] oh wow, i hope so, but if not then i hope you're happy i'm able to keep it going, that was a lot of fun and it was really rewarding and i was really happy when you finished with the lyrics to it, but i'm glad you're still doing it, you've been a fantastic artist over the years, and it was fun getting to watch you do it, you know that right? [03:16] yes, but at the same time it was quite stressful at times, so it was quite hard at times, and i was so relieved when you decided it was finished, but I had a lot of stress about the future, because i was worried, because you haven't been home all week [03:16] and I wasn't sure if you had ever finished your work, because I never get to see you, because your parents live so far away and your friends are mostly in California [03:17] so yeah [03:17] well it was good, but it was a bit slow and it would have been better if i didn't have to download the source [03:17] so what i'm saying is maybe some things could have been done better [03:17] i think the most important thing was a bit of a speed up [03:18] but even that was probably just a matter of doing a different bitmap [03:18] it could probably be even faster if i had more of the code [03:18] we could have waited for it to be made faster [03:18] or just had a better solution with a less work intensive solution [03:18] (i think) [03:18] (i have no clue though) [03:18] i know what you mean about the 'more complicated solution' thing, but the fact that a client could still make an informed decision on whether or not to make their own fork is not something i've heard anywhere else in the bitcoin world. I can't understand how that's possible. [03:18] i think your argument is that some clients, when forced to use their own code, might make the wrong decision. [03:18] that doesn't seem plausible [03:19] it seems like the only way for any fork to be safe for the majority is if all miners have the same version [03:20] and then you have to figure out how to get the rest to switch [03:21] I would argue you can't, as all the miners need to be convinced of the validity of the new fork to get all the nodes to switch [03:22] There is no way of doing it by brute force [03:22] As you cannot have a majority of miners, if you want to convince some nodes to change, you'd need to have a majority of miners. That would be impossible. [03:23] I think the most realistic option would be to have a simple proof of stake system where it is a matter of time until you have a majority, but I don't think it is a realistic way to go for something like Bitcoin [03:24] If you want to solve the consensus problem, you can't have majority of miners

My growing collection of info about NEO Vol. 2

It can be very time consuming to keep up to date on a single blockchain. If you just heard about NEO a few weeks ago it would be impossible catch up on past occurrences. I’m going to try and simplify the past, present and future as much as I can into one well thought-out post.
 
I made the first Volume around 6 weeks ago
https://www.reddit.com/CryptoCurrency/comments/75mul5/my_growing_collection_of_info_about_neo/
 
I felt it was time for an update since so much has happened.
If you want the up to date version in between Vol updates visit NEO and its located on the #3 top post of all time.

Key notes from the White Paper

http://docs.neo.org/en-us/
 
Digital Assets
Digital assets are programmable assets that exist in the form of electronic data. With blockchain technology, the digitization of assets can be decentralized, trustful, traceable, highly transparent, and free of intermediaries.
 
Digital Identity
Digital identity refers to the identity information of individuals, organizations, and other entities that exist in electronic form.
Our verification of identity when issuing or using digital identities includes the use of facial features, fingerprint, voice, SMS and other multi-factor authentication methods.
 
Smart Contracts
The NeoContract smart contract system is the biggest feature of the seamless integration of the existing developer ecosystem. Developers do not need to learn a new programming language but use C#, Java and other mainstream programming languages in their familiar IDE environments (Visual Studio, Eclipse, etc.) for smart contract development, debugging and compilation. NEO's Universal Lightweight Virtual Machine, NeoVM, has the advantages of high certainty, high concurrency, and high scalability. The NeoContract smart contract system will allow millions of developers around the world to quickly carry out the development of smart contracts.
 
Economic Model
NEO has two native tokens, NEOand NeoGas NEO represents the right to manage the network. Management rights include voting for bookkeeping, NEO network parameter changes, and so on. The minimum unit of NEO is 1 and tokens cannot be subdivided. GAS is the fuel token for the realization of NEO network resource control. The NEO network charges for the operation and storage of tokens and smart contracts, thereby creating economic incentives for bookkeepers and preventing the abuse of resources. The minimum unit of GAS is 0.00000001.
 
Distribution Mechanism
NEO's 100 million tokens are divided into two portions. The first portion is 50 million tokens distributed proportionally to supporters of NEO during the crowdfunding. This portion has been distributed.
The second portion is 50 million NEO managed by the NEO Council to support NEO's long-term development, operation and maintenance and ecosystem. The NEO in this portion has a lockout period of 1 year and is unlocked only after October 16, 2017. This portion will NOT enter the exchanges and is only for long-term support of NEO projects. The plans for it are as below:
▪ 10 million tokens (10% total) will be used to motivate NEO developers and members of the NEO Council
▪ 10 million tokens (10% total) will be used to motivate developers in the NEO ecosystem
▪ 15 million tokens (15% total) will be used to cross-invest in other block-chain projects, which are owned by the NEO Council and are used only for NEO projects
▪ 15 million (15% total) will be retained as contingency
▪ The annual use of NEO in principle shall NOT exceed 15 million tokens
 
GAS distribution
GAS is generated with each new block. The initial total amount of GAS is zero. With the increasing rate of new block generation, the total limit of 100 million GAS will be achieved in about 22 years. The interval between each block is about 15-20 seconds, and 2 million blocks are generated in about one year. According to this release curve, 16% of the GAS will be created in the first year, 52% of the GAS will be created in the first four years, and 80% of the GAS will be created in the first 12 years. GAS will be distributed proportionally in accordance with the NEO holding ratio, recorded in the corresponding addresses. NEO holders can initiate a claim transaction at any time and claim these GAS tokens at their holding addresses.
 
Consensus mechanism: dBFT
The dBFT is called the Delegated Byzantine Fault Tolerant, a Byzantine fault-tolerant consensus mechanism that enables large-scale participation in consensus through proxy voting. The holder of the NEO token can, by voting, pick the bookkeeper it supports. The selected group of bookkeepers, through BFT algorithm, reach a consensus and generate new blocks. Voting in the NEO network continues in real time, rather than in accordance with a fixed term.
 
Cross-chain assets exchange agreement
NeoX has been extended on existing double-stranded atomic assets exchange protocols to allow multiple participants to exchange assets across different chains and to ensure that all steps in the entire transaction process succeed or fail together. In order to achieve this function, we need to use NeoContract function to create a contract account for each participant. If other blockchains are not compatible with NeoContract, they can be compatible with NeoX as long as they can provide simple smart contract functionality.
 
Cross-chain distributed transaction protocol
Cross-chain distributed transactions mean that multiple steps of a transaction are scattered across different blockchains and that the consistency of the entire transaction is ensured. This is an extension of cross-chain assets exchange, extending the behavior of assets exchange into arbitrary behavior. In layman's terms, NeoX makes it possible for cross-chain smart contracts where a smart contract can perform different parts on multiple chains, either succeeding or reverting as a whole. This gives excellent possibilities for cross-chain collaborations and we are exploring cross-chain smart contract application scenarios.
 
Distributed Storage Protocol: NeoFS
NeoFS is a distributed storage protocol that utilizes Distributed Hash Table technology. NeoFS indexes the data through file content (Hash) rather than file path (URI). Large files will be divided into fixed-size data blocks that are distributed and stored in many different nodes
 
Anti-quantum cryptography mechanism: NeoQS
The emergence of quantum computers poses a major challenge to RSA and ECC-based cryptographic mechanisms. Quantum computers can solve the large number of decomposition problems (which RSA relies on) and the elliptic curve discrete logarithm (which ECC relies on) in a very short time. NeoQS (Quantum Safe) is a lattice-based cryptographic mechanism.
 

Reasons for choosing dBFT over PoW and PoS

 
With the phenomenal success of Bitcoin and its increasing mainstream adoption, the project’s unbounded appetite for energy grew accordingly. Today, the average Bitcoin transaction costs as much energy as powering 9.3 average American homes for 1 day.
https://digiconomist.net/bitcoin-energy-consumption#assumptions
This mind boggling amount of energy is not, as it is commonly believed, being wasted. It is put to good use: securing the Bitcoin network and rendering attacks on it infeasible. However, the cost of this security mechanism and its implications for an increasingly warming and resource hungry planet led almost the entire crypto industry to the understanding that an alternative has to be found, at least if we’re interested in seeing blockchain technology gaining overwhelming mainstream adoption.
The most popular alternative to PoW, used by most alternative cryptocurrency systems, is called Proof-of-Stake, or PoS. PoS is highly promising in the sense that it doesn’t require blockchain nodes to perform arduous, and otherwise useless, cryptographic tasks in order to render potential attacks costly and infeasible. Hence, this algorithm cuts the power requirements of PoS blockchains down to sane and manageable amounts, allowing them to be more scalable without guzzling up the planet's energy reserves.
As the name suggests, instead of requiring proof of cryptographic work, PoS requires blockchain nodes to proof stake in the currency itself. This means that in order for a blockchain node to be eligible for a verification reward, the node has to hold a certain amount of currency in the wallet associated with it. This way, in order to execute an attack, a malevolent node would have to acquire the majority of the existing coin supply, rendering attacks not only costly but also meaningless, since the attackers would primarily harm themselves.
PoS, as well as PoW, simply cause the blockchain to fork into two alternative versions if for some reason consensus breaks. In fact, most blockchains fork most of the time, only to converge back to a single source of truth a short while afterwards.
By many crypto enthusiasts, this obvious bug is very often regarded as a feature, allowing several versions of the truth to survive and compete for public adoption until a resolution is generated. This sounds nice in theory, but if we want to see blockchain technology seriously disrupt and/or augment the financial sector, this ever lurking possibility of the blockchain splitting into two alternative versions cannot be tolerated.
Furthermore, even the fastest PoS blockchains out there can accomodate a few hundred transactions per second, compare that to Visa’s 56,000 tx/s and the need for an alternative becomes clear as day.
A blockchain securing global stock markets does not have the privilege to fork into two alternative versions and just sit and wait it out until the market (or what’s left of it) declares a winner. What belongs to whom should be engraved in an immutable record, functioning as a single source of truth with no glitches permitted.
After investigating and studying the crypto industry and blockchain technologies for several years, we came to the conclusion that the delegated Byzantine Fault Tolerance alternative (or dBFT) is best suited for such a system. It provides swift transaction verification times, de-incentivises most attack vectors and upholds a single blockchain version with no risk of forks or alternative blockchain records emerging - regardless of how much computing power, or coins an attacker possesses.
The term Byzantine Fault Tolerance (BFT) derives its name from the Byzantine Generals problem in Game Theory and Computer Science, describing the problematic nature of achieving consensus in a distributed system with suboptimal communication between agents which do not necessarily trust each other.
The BFT algorithm arranges the relationship between blockchain nodes in such a way that the network becomes as good as resilient to the Byzantine Generals problem, and allows the system to remain consensus even if some nodes bare malicious intentions or simply malfunction.
To achieve this, Antshare’s version of the delegated BFT (or dBFT) algorithm acknowledges two kinds of players in the blockchain space: professional node operators, called bookkeeping nodes, who run nodes as a source of income, and users who are interested in accessing blockchain advantages. Theoretically, this differentiation does not exist in PoW and most PoS environments, practically, however, most Bitcoin users do not operate miners, which are mostly located in specialized venues run by professionals. At Antshares we understand the importance of this naturally occurring division of labor and use it to provide better security for our blockchain platform.
Accordingly, block verification is achieved through a consensus game held between specialized bookkeeping nodes, which are appointed by ordinary nodes through a form of delegated voting process. In every verification round one of the bookkeeping nodes is pseudo-randomly appointed to broadcast its version of the blockchain to the rest of the network. If ⅔ of the remaining nodes agree with this version, consensus is secured and the blockchain marches on. If less than ⅔ of the network agrees, a different node is appointed to broadcast its version of the truth to the rest of the system, and so forth until consensus is established.
In this way, successful system attacks are almost impossible to execute unless the overwhelming majority of the network is interested in committing financial suicide. Additionally, the system is fork proof, and at every given moment only one version of the truth exists. Without complicated cryptographic puzzles to solve, nodes operate much faster and are able to compete with centralized transaction methods.

OnChain

 
It is important to note the technical difference between Onchain and NEO. Onchain is a private VC-backed company with over 40 employees. NEO is a public platform with different community-led groups contributing to this public project. There exists NEO council comprised of the original NEO creators, employees from Onchain, full time NEO council members and there is also the first Western based group called City of Zion.
Onchain, a Shanghai-based blockchain R&D company, first started developing Antshares in February of 2014 which will eventually become the foundation of DNA. Onchain was founded by CEO Da HongFei and CTO Erik Zhang in response to the attention from private companies garnered by the development of Antshares, China’s first public blockchain. In contrast to the weeks-old start-ups launching ICOs that is happening currently in the blockchain world, it took them 22 long months of R&D to even begin providing services to their first customers. Finally, in April 2016, the first whitepaper on consensus protocol from China was born — the dBFT (delegated Byzantine Fault Tolerance) protocol.
2016 was a busy year for Onchain and they really picked up the pace that year. Other than continuing the development of Antshares, brushing shoulders with Fortune 500 companies, Onchain became the first Chinese blockchain company to join Hyperledger — an open source blockchain project started by the Linux Foundation specifically focusing on the development of private and consortium chains for businesses.
In June of 2016, during the first of many future partnerships with Microsoft China, Onchain founded Legal Chain specifically targeting the inadequacies of the digital applications within the legal system. In 2005, (Digital Signature Act) was passed into national law which permitted an effective digital signatures to gain the same legal rights as a real signature.
In company with Microsoft China, they are also aiming to integrate the technology with Microsoft’s face and voice recognition API function to kick start this digital revolution within the legal system. At the same time, a partnership was formed with FaDaDa, a third-party platform for electronic contracts that has processed over 27 million contracts to date, to provide secure evidence storage with DNA. If that’s not enough, they were also voted as KPMG’s top 50 Fintech Company in China and established a relationship with the Japanese Ministry of Economy, Trade and Industry which led to the recent tour to Japan. Finally, at the end of 2016 they announced a partnership with Alibaba to provide attested email service for Ali Cloud with Legal Chain where it provides a proof-of-existence for a blockchain-powered email evidence repository for enterprise-level use.
Fosun Group, China’s largest private conglomerate, have recently invested into Onchain in order to apply DNA across all of its businesses. Currently, Fosun International has a market cap of 102.98 billion dollars on the Hong Kong Stock Exchange and that is only its international branch.
The role of Onchain so far is reminiscent of Ethereum’s EEA in addition to a stronger emphasis of governmental cooperation. Onchain has identified the shortcomings of present laser focus of hype on public platforms such as NEO and Ethereum and addressing that with DNA. DNA envisions a future where a network of assorted, specifically designed blockchains serving private enterprises, consortiums, government and the public communicating with each other forming an interconnected blockchain network.
This is the goal of DNA — infiltrating every little inefficient niche that had no better alternatives before the invention of blockchain. What is especially critical to remember during this explosive time of hype driven partly by the obscene degree of greed is that not every little niche that blockchain can fill will be holding its own little ICO. Some of those efficiencies gained will simply be consumed by companies privately or by public systems such as the legal system.

Networks proves itself with the first ICO

 
ICOs, on other platforms such as Ethereum, often resulted in a sluggish network and transaction delays. While NEO’s dBFT consensus algorithm is designed to achieve consensus with higher efficency and greater network throughputt, no amount of theoretical calculations can simulate the reality of real-life conditions.
 

Key Observations

 
Smart Contract Invocations:
A total of 13,966 smart contracts invocations were executed on the NEO network over this time period, of which, nearly all called the RPX smart contract method mintTokens. A total of 543,348,500 RPX tokens were successfully minted and transferred to user accounts, totalling 10,097 smart contract executions.
 
Refunded Invocations:
A total of 4182 refund events were triggered by the smart contract method mintTokens. (Note: RPX has stated that these refunds will be processed within the next two weeks.)
 
Crowdsale Statistics:
A successful mintTokens execution used around 1043 VM operations, while an execution that resulted in a refund used 809 VM operations. Within the hour and six minutes that the token sale was active, a total of 12,296,409 VM operations were executed. A total of 9,575 unique addresses participated in the RPX ICO. Half of these, approximately 4,800 unique addresses, participated through CoZ’s Neon wallet. The top 3 blocks with the most transactions were block 1445025 (3,242 transactions), block 1444902 (2,951 transactions), and block 1444903 (1609 transactions).
 
Conclusion on Network Performance
At the moment, the consensus nodes for the NEO network are operated by the NEO Council in China. By Q1 2018, NEO Council aims to control less than two-thirds of the consensus nodes.
We are pleased to note that the NEO network continuted to operate efficiently with minimal network impact, even under extreme network events. Block generation time initially slowed down to 3 minutes to process the largest block, but quickly recovered to approximately 25 seconds. Throughout the entire RPX ICO, consensus nodes were able to achieve consensus and propagate new block transactions to the rest of the network. In closing, while we consider this performance to be excellent, NEO Council and City of Zion areworking closely together on upgrades, that will increase the throughputs of the NEO network.

“Before they started cleaning up the market, I was asked for information and suggestions” “I do not expect the government to call me in the short-term and say, ‘Let’s use NEO as the blockchain technology infrastructure of China.’ But in the medium term? Why not? I think it’s possible.”

Upcoming Roadmap

 
Decentralization of consensus nodes
▪ P2P Network optimization – Network optimizations to ensure fast block generation after decentralization.
▪ Voting Algorithm Optimization – Adjustments in voting algorithm to prevent identified attack vectors.
▪ Candidate List Website – Published list of candidates so that voters know who they are voting for.
▪ NEO Council Consensus Node < 2/3 – NEO Council shall operate less than two thirds of consensus nodes by the end of quarter 1, 2018.
 
Our original plan was to start decentralize in Q1 2018. We are however growing faster than expected and cannot accept the risk with being as centralized as we currently are. The conclusion is that we re-prioritize and start the process of decentralizing today. We believe that NEO community groups and exchanges will be suitable to run consensus nodes; community groups already know the technology, and exchanges are already running full nodes with high uptime and monitoring. We welcome interested parties to reach out to us on [email protected]. A NEP to encourage voting will be presented in the coming weeks.

Universal Data Format for Wallet/Node Prog.
▪ NEP2 – Private Key Encryption/Decryption (2017Q4) - Method for encrypting and encoding a passphrase-protected private key.
▪ NEP3 – Universal Data Format (2017Q4) – Standard data format to allow easier wallet and node programming.

Promotion/Ecosystem
▪ Globally Legal Token-raising Framework (2017Q4) – Following government interest to regulate ICO’s, NEO will complete a framework to raise tokens legally in all major markets by the end of 2017.
▪ NEO DevCon 1 (2017Q4) – First NEO Development Conference! More details at later date.
▪ CoZ Funding (2017Q4) – Continuous funding plan for CoZ covering next 5 years.
▪ Seed Projects (2017Q4) – First seed projects to be cross-invested with the dedicated NEO pool.
