Consensus is certainly not a necessary element of a blockchain. A blockchain can just as easily exist under the control of a central authority, as it could under any other circumstances. Unless you mean that you’re still achieving consensus by simply trusting the central authority, which I guess is technically correct, but that’s not how ‘consensus’ is generally used in relation to blockchains, it’s generally used to refer to trustless distributed consensus.

- AmericanChopper 8y agoWhat makes git different from a blockchain? A blockchain is a data structure, and a data structure doesn’t change based on who has permission to write to it.
- acdha 8y agoThose terms don’t have the meanings you’re using. Being a data structure is not a distinguishing factor – try finding a common definition which excludes Git – and there’s no definition of the term which excludes modifications.
- AmericanChopper 8y agoI’m not sure why you’re trying to say. The data structure is immutable by design. You can’t modify a git commit. But you haven’t answered my question. What’s the difference between a blockchain, and git?
