You're using an arbitrary, uncommon definition of blockchain. A blockchain is a Merkle tree of validated transactions with a consensus algorithm.

  That is the definition of blockchain. It's what was invented in Bitcoin. All other definitions would suggest blockchains were invented in the 90s or 80s

  thats the best consolidated broad definition of a blockchain I've heard. Do you mind if I use it? Should we also include elliptic curve signatures?
  • brighton36 11y ago
    It's a terrible definition. There's no mention of pow, which was the innovation of Bitcoin, and that which secures the network

    Some kind of public key signature seems essential, doesn't necessarily have to be elliptic curves. There's already talk about using post-quantum algorithms. But verifying the signature is part of the validation algorithm, so "validated transactions" already covers it.
