Nonsense. Bitcoin software releases come with widely publicized checksums and signatures from reputable sources.
- dane-pgp 6y agoCouldn't those reputable sources also provide widely publicized checksums and signatures for a pruned blockchain state?
- tromp 6y agoThe pruned blockchain state changes every block. More importantly, Bitcoin is ideologically opposed to the idea of checkpoints, as they run counter to the Longest Chain Rule that says the true state is whatever valid chain has the most cumulative work. Even if that chain is the result of a very deep reorg that invalidates the last checkpoint.
- CryptoPunk 6y agoI am only including those "widely publicized checksums and signatures from reputable sources" in my definition of "software distribution channel".
