> “Blockchain, the ledger software that makes the digital currency possible” Huh? The blockchain is a name for a feature of the Bitcoin protocol. It's not a piece of software and it's not a proper noun. But you'd be forgiven for not knowing that, given the constant hype about “blockchains” these days and their use as a hammer to try and hit every imagined nail. There's also a company named after it, which is a proper noun. The blockchain, incidentally, is not mentioned in the Bitcoin white paper,[0] which refers to a “proof-of-work chain”. “Blockchain”, as a word, was merely internal jargon to refer to Bitcoin's specific implementation of this concept.
