66 I thought we’d finally get rid of bitcoin. 52 Cryptocurrencies are a hot-bed for criminal activity so it’s no surprise that the innocent make easy prey. 87 Bitcoin’s advocates claim that it is immune from government control. It was NOT simply because energy was cheap. 02 Warren Buffett is still not a fan of investing in bitcoin.

62 Three ways Bitcoin could be brought down, co-opted, or made irrelevant. 81 Blockchain hype is an essential part of the crypto-craze, and its fading is cause to expect the eventual crash. 81 The Nobel Prize-winning economist sees the cryptocurrency as more of a psychological experiment than a serious investment. 53 Nicholas Weaver, a researcher at the International Computer Science Institute at UC Berkeley.

58 The greatest bubble in history is popping, according to Bank of America Corp. A section and I’ll do my best to respond within 24 hours. 67ハッシュ and Russian: Майним Bitcoin с помощью бумаги и ручки. I decided to see how practical it would be to mine Bitcoin with pencil and paper. It turns out that the SHA-256 algorithm used for mining is pretty simple and can in fact be done by hand. Not surprisingly, the process is extremely slow compared to hardware mining and is entirely impractical. But performing the algorithm manually is a good way to understand exactly how it works.

The mining process Bitcoin mining is a key part of the security of the Bitcoin system. The idea is that Bitcoin miners group a bunch of Bitcoin transactions into a block, then repeatedly perform a cryptographic operation called hashing zillions of times until someone finds a special extremely rare hash value. At this point, the block has been mined and becomes part of the Bitcoin block chain. The SHA-256 algorithm consists of a relatively simple round repeated 64 times.

The diagram below shows one round, which takes eight 4-byte inputs, A through H, performs a few operations, and generates new values of A through H. The blue boxes mix up the values in non-linear ways that are hard to analyze cryptographically. Since the algorithm uses several different functions, discovering an attack is harder. If you could figure out a mathematical shortcut to generate successful hashes, you could take over Bitcoin mining. The Ma majority box looks at the bits of A, B, and C.
