Cryptographically immutable append only ledgers (aka merkel trees) have existed since at least 1979. A blockchain is different because it has distributed consensus. If your consensus algorithm is trust, then it’s not a fucking blockchain.
A blockchain is nothing more than a data structure. It’s essentially a linked list using the hash of the previous block. Distributed consensus is something blockchains are useful for, but it doesn’t define it

Nah, you can pretty easily define a Blockchain as a special case of a Merkel tree with a distributed consensus method.
No, that’s a Merkel tree. Been around since 1979.
