Git is decentralized append-only tamper-resistant ledger aka “blockchain”.

  I think append-only ledgers and specifically BFT distributed ledgers have obvious uses. The question is whether you can call them blockchains (I'd argue that you can't) and whether the added traits of a blockchain have any additional benefit.

    Can you speak to the 'obvious' uses? They are not obvious to me unfortunately.

      Append-only ledgers have been used for a while and pre-date the concept of blockchain. Some accounting systems use them. Other examples are IPFS (which uses Bitcoin technology but technically doesn't need to), Internet Archive, some types of event logs, some message queues, chain-of-custody applications, and some P2P marketplaces. As for Byzantine fault tolerance, it's a bit more of a niche. The most famous examples I know of are extremely high-risk situations, like aircraft software. I don't fully understand how it's used there, but to my knowledge, it prevents "bad" signals (from malfunctioning sensors, cosmic rays, etc.) from corrupting the rest of the data that controls the hardware.

  Can you clarify? Git? The software I use to: git add * --- This is a private 'blockchain' based on a project? So there isnt any 'coins' that are going to be doing similar worldwide? Can you make an attempt to come up with the worldwide or coin usage that solves a verification problem similar to git? Very interesting btw
