How Bitcoin Works...

Bitcoin is the future of money. It's the first decentralized digital currency that works person-to-person without needing a bank of central repository.
What is Mining? Mining is the backbone that allows Bitcoin to function. New Bitcoins are created as a reward for miners who secure & verify payments in the blockchain.

Could SPV Support a Billion Bitcoin Users? Sizing up a Scaling Claim

Jameson Lopp is a software engineer at BitGo, creator of statoshi.info and founder of bitcoinsig.com. In this opinion piece, Lopp takes a deep dive into claims that it's safe to remove bitcoin's block size limit and instead rely on existing "simplified payment verification" (SPV) methods. A new claim is being perpetuated in the bitcoin scaling debate. We're hearing that it is safe to remove the block size limit because bitcoin can easily scale to huge block sizes that would support billions of users via existing "simplified payment verification" (SPV) methods. Supposedly, SPV is very scalable due to the small amount of data it requires an SPV client to store, send and receive. Let's dig into this claim and examine it from multiple perspectives. How SPV worksSatoshi described the high-level design for SPV in the bitcoin white paper, though it wasn't implemented until two years later when Mike Hearn created BitcoinJ.
Early SPV implementations were q…

'First' Ethereum Decompiler Launches With JP Morgan Quorum Integration

The ethereum virtual machine (EVM) now has what appears to be its first ever decompiler designed to revert smart contracts into source code. Announced onstage today by the founder of cybersecurity startup Comae Technologies at the DefCon hacker conference in Las Vegas, the open-source EVM decompiler was designed to make it easier to identify bugs in ethereum smart contracts. Coming at a time when a string of ethereum hacks have exposed the difficulty of writing secure smart contract code, the decompiler, called Porosity, promises to let developers revert difficult to understand EVM bytecode back to its original state. Porosity developer and Comae founder, Matt Suiche, told CoinDesk: "The initial problem I was trying to solve by writing a decompiler is to be able to have the actual source code, without having access to the actual source code by reverse engineering." Also announced today, Porosity is now integrated with JP Morgan's open-source Quorum blockchain created fo…
