See on Github It was 2013 when I first dove into Bitcoin as a (wannabe) developer and since then I hoarded a remarkable amount of websites, articles, readings, threads, mailing lists.Well, it’s been 2 years and I can still see a clear, major bottleneck: we fall extremely short of developer resources.While it may be a matter of pioneering (is it really?we’re far beyond 2009…), when it comes down to investors, politics and philosophy we all agree that Bitcoin is in the spotlight.Why is Bitcoin development so elitist?I truly believe this aspect alone defeats the motivations behind Bitcoin and I realized there’s a steep learning curve in front of those willing to step in.Let alone bitcoinj providing very well for Java programmers, the support for other languages sadly looks like Google Code.Even the frameworks for the JavaScript + Node.js platform are mostly a work in progress and those who aren’t often miss out on the networking tier.The renowned BitPay’s Bitcore is no exception.

Given the above, many enthusiasts out there might not have the tools or the time to join the active side of the community.As of today, reinventing the wheel at times may be as unreasonable as unavoidable.The goal of this series is speeding up the learning process by providing a step-by-step description of the blockchain from a programmer perspective.No in-depth experience is required, I only assume: Ideally, you’ve had a wallet once in your life and possibly used it to send or receive some coins.You’ve been flooded by hundreds of articles and wikis worshipping the revolutionary nature of the blockchain, but you’ve been curious enough to read past the buzzwords.You may have taken a peek at websites like blockchain.info to gain insight into your own transactions or just for the sake of tasting the hackerish side of the thing.Skip the math behind the mining process, still you know that bitcoins spring out of an algorithm somehow.Well, that’s how far I expect you to have gone.Meanwhile there’s plenty of wikis and articles explaining way better than me what the blockchain is and why it’s such an awesome discovery by the human being.

Here I’ll cover the Bitcoin transaction system and teach you how to assemble your own transactions.bitcoin 25000Since the beginning, I’ll draw a path leading you to understanding how the high-level blockchain entities translate to raw bytes.soros on bitcoinNuts and bolts, no big deal.bitcoin etf commentsI’ll start with a few theoretical concepts to make better sense of the code snippets attached but trust me, I want this series to be practical.ethereum initial offeringHowever, this is a beginner course and it’ll take you a little more to get your feet wet with the Bitcoin Core codebase.bitcoin litecoin wiki

It has been recently legalized by California.Bitcoin can be earned by helping verifying transaction, aka, mining.Mining is essentially computing hashes, many many of them.This article will walk you through how to start mining bitcoin with a graphics card on a commodity PC.The first step is to setup a wallet to store your money(Bitcoin).There are a bunch of choices, you can choose to setup a local wallet on your computer or choose a online service.I chose to use coinbase because it’s easy to setup.You will get a bitcoin address like 1NpnrNH12JGLhCdHrMLSZhNptnVVPfvafy which identifies a digital wallet.It can be used to send or receive bitcoins.You will work with a group of other miners by joining a pool.A list of available pools can be found here.I chose the Slush’s pool as an example.After setting up your account.Put in your bitcoin address in the My Account page.In the same page, you will find one worker has been created.Its login and password will be used later by the miner.One worker is needed for each miner you setup.

There are a lot of miner options.You choose a miner based on your hardware and operating system.Various kinds of hardware have been used for bitcoin mining, for example: CPU, GPU, ASIC, FPGA, etc. My desktop PC is running Ubuntu 12.04 and has a radeon HD 6670 graphics card.There is a post about setting up CGMiner on XUbuntu.Not all the instructions work for me, so here is what I did for your reference: Download the driver from here.Follow the instructions in the installer.Check your card can be found by: You are expecting this as output: Note: You’d better don’t use newer version of cgminer since versions after 3.7.2 don’t support GPU anymore per this post.Write a shell script to run cgminer: Cgminer looks like this when it’s running.You can find your current hash rate, GPU temperature and many other information.Bitcoin mining speed is measured hash rate whose unit is Mhash/s which means million hashes per second.That number largely depends on the hardware used.
