blockchain isn't inefficient because it's p2p. it's inefficient because it assumes peers are untrustworthy and solves for that by imposing a proof of work, requiring cooperative peers to waste more electricity than bad actors.

[beeflet]

assuming peers are trustworthy is assuming away the whole problem.

The problem isn't with p2p, but specifically with full-sync mutexes in p2p. There are petname systems that avoid the problem by avoiding the mutex itself, and there are centralized systems that avoid the p2p, but it comes down to zooko's trilemma.
