Bitcoin - The Currency of the Internet
A community dedicated to Bitcoin, the currency of the Internet. Bitcoin is a distributed, worldwide, decentralized digital money. Bitcoins are issued and managed without any central authority whatsoever: there is no government, company, or bank in charge of Bitcoin. You might be interested in Bitcoin if you like cryptography, distributed peer-to-peer systems, or economics. A large percentage of Bitcoin enthusiasts are libertarians, though people of all political philosophies are welcome.
/btc was created to foster and support free and open Bitcoin discussion, Bitcoin news, and exclusive AMA (Ask Me Anything) interviews from top Bitcoin industry leaders! Bitcoin is the currency of the Internet. A distributed, worldwide, decentralized digital money. Unlike traditional currencies such as dollars, bitcoins are issued and managed without the need for any central authority whatsoever.
Check out the 21 Bitcoin computer. It's gaining engineering traction.
What brought me to bitcoin was folks writing complex code and building interesting things with programmable money that was simply impossible before. I just got my 21 computer in the mail and for all its failings as a terrible miner and expensive hardware, it's biggest win is worth the cost: Watching, learning and sharing code and ideas with bitcoin engineers. Writing apps on the 21 platform is fun and rewarding. If you've dismissed the 21 machine, I recommend spending the $400, getting one . Join the engineering community experimenting and exploring what bitcoin can do. NOTE: I'm neither employed/paid/endorsed by 21. I just stumbled into their community and liked the code created.
[TUTORIAL] Turn your $35 Raspberry Pi into a 21 Bitcoin Computer! (original post deleted)
I noticed that ButtcoinEE deleted his own tutorial from here, and I liked the information provided, so I'm reposting it for others who may not have it saved. I haven't tested his tutorial on my own RPI yet, but if anyone wants to give it a go, I can update this as needed. Below is the post directly quoted from OP: You get your brand new RPI and
It's supported operation in the code supplied by the company.
That is not honest given that you cannot reproduce everything that the 21 Bitcoin Computer can do right now. You don't have the integrated framework. You would be doing something very different and that is not an honest comparison.
The script linked is literally what sets up the 21 Bitcoin Computer, it's identical in software in every way.
RE: 21 Bitcoin Computer and preloading bitcoin instead of mining
Why the mining chip when it's apparently cheapeeasier to preload some bitcoin?
Get developers familiar with the concept of having bitcoin as a system resource.
Possibly avoid regulatory/legal/policy hurdles. This way it's just some product you can buy on amazon.
Buffered Mining: "As soon as your 21 Chip connects to the 21 Pool we begin streaming you a pro-rata share of your mined bitcoin". You don't need to wait for the 21 pool to find a block to begin receiving bitcoin. This requires that you can't change the mining pool, which in return requires the custom chip. In the future, different chips will probably point to different pools to counteract miningpool centralization.
Mining decentralization: "The more small devices that run at a loss, the more pressure will be put on large for profit miners. Eventually, large miners will go out of business and billions of not-for profit miners will secure the network. Natural decentralization through open technology." (llortoftrolls)
Tested, step-by-step tutorial to run a 21 Bitcoin Computer as a virtual machine
Many thanks to ButtcoinEE and ecafyelims for initial pointers, but if I understood correctly, both users said they hadn't actually tried it themselves. So here comes a tutorial based on something I actually tried. Best of all: You don't even need a Raspberry Pi! We'll run it as a virtual machine. The first step is to get a Debian 8 (Jessie) installation up and running. You might want to install that inside a VMWare/Virtualbox machine. I'll be using Vagrant here ( https://www.vagrantup.com/ ) which makes it easy to manage virtual machines like that and already has a Debian 8 image in the catalog. So get Vagrant for your platform and then do something like this:
vagrant init ARTACK/debian-jessie vagrant up
You should now be able to SSH into the machine:
Now that we have a Debian up and running, let's first get some packages we'll need later:
sudo su # become root apt-get update apt-get upgrade apt-get install apt-transport-https git cython3 python3-setuptools
It'll complain about a missing GPG key, but you can just ignore that. We should be able to do 'apt-get install two1' now, but it complains about a missing package 'python3-sha256'. The reason for that is probably, that we are doing this on a x86 architecture, where the packages are slightly different than the Raspberry Pi's ARM architecture. So we'll just manually install the package and have it ignore the dependency errors:
We'll have to extract the credentials for the specific network they use from 21's zerotier package:
mkdir credentials cd credentials wget https://apt.21.co/pool/z/ze/zerotier-one_1.1.0-1_armhf.deb ar x zerotier-one_1.1.0-1_armhf.deb tar xf data.tar.xz cp valib/zerotier-one/updates.d/ZeroTierOneInstaller-linux-armv6l-1_1_0 /valib/zerotier-one/updates.d/
Before we join the network, we need to lock down our machine. That's actually a bit tricky, as these Vagrant images aren't really designed with security in mind, but rather only to be used for local testing. I think it should be enough to do:
Note that you won't be able to use 'vagrant ssh' any longer afterwards, as we just deleted the standard Vagrant key-based login. You'll have to use 'ssh [email protected]' instead. Now we are ready to join the network:
wget https://gist.githubusercontent.com/balajis/6d495bb40fb157a58677/raw/21-join.py python3 21-join.py python3 21-join.py # might have to try this twice as well ifconfig zt0 # will show your new IP within the VPN
The 21 tools have a concept of both an on-chain balance and an off-chain balance - the latter being managed by 21's server. You can deposit to your on-chain balance, but currently the only way to increase the off-chain balance is by mining or by receiving payments from others. Without the mining chip it's therefore a bit tricky to increase that off-chain balance. I hear that a feature request is being considered, to allow moving funds from on-chain to off-chain. That's all! If you want to give it a shot, you should probably move fast, as 21 has some DRM in the works, as per this comment: https://www.reddit.com/Bitcoin/comments/3tnjz7/tutorial_turn_your_35_raspberry_pi_into_a_21/cx7tih3 .

The 21 Bitcoin Computer is produced by 21 Inc, one of the most prominent Bitcoin startups funded by the famous venture capital firm Andreessen Horowitz.It is also known as the first Bitcoin computer in the world. Given the reputation of its manufacturer and the anticipation and excitement of the Bitcoin community, I decided that it was worthwhile to buy this Bitcoin device and learn more about it. Most people know the 21 Inc company as the group behind the Bitcoin computer. But under the hood, there is a vast open source library waiting to be explored and expanded. While I am familiar with Bitcoin, I know little about Bitcoin payment processing. I have several purpose-built computers, but I preferred to buy this device instead of building one. In terms of time saved, I think I made a good choice. In less than an hour after I received the 21 computer, it was up and mining and using the APIs. 21 Bitcoin Computer. The 21 Bitcoin Computer isn’t the typical USB Bitcoin miner. It does, however, plugin to your computer via USB. In terms of $ / hash rate, it’s not a very good choice. But since it’s still technically a USB miner we have included it in this list. If you’re not impressed, we don’t blame you! 21 (21 Bitcoin computer) is a software that is able to turn any computer into a Bitcoin Computer.What is interesting, it’s possible to get Bitcoin on any device in almost any country without a bank account or credit card. It is possible to earn money on HTTP requests. Using this software, customers get open documentation for development and the newest information about Bitcoin fees.
