The maintainer must decide which blocks are valid. That's just as much of a consensus algorithm as Bitcoin just not as distributed and decentralized.

- pests 9y agoBut isn't that exactly the point? That decision, with Bitcoin, is distributed and decentralized. We've always been able to decide how to add an element to the end of a (possibly cryptographically secure) chain of blocks. What separates the two definitions of blockchain in this thread is exactly the distributed and decentralized choosing of the top block.
- tscs37 9y agoYes, bitcoin is decentralized and distributed. But blockchains don't have to be inherently.
