1000 validators is very centralized. All you have to do is bribe 2/3rds of them control the chain. This is on top of Solana not having slashing in place to punish bad behavior, and the Solana Foundation hosting validators for people who want to delegate.

Solana’s 1000 validators may not even be owned by 1000 different entities, which reduces the attack difficulty.

Solana scales through centralization, not new ideas in blockchain scalability.

I don’t care how many Bitcoin mining pools there are. Mining pools are different than validators since they are made up of different individuals and not a single controlling entity. I also think PoW should die, and that’s all Bitcoin will ever support.

Edit: if all we want is 1000 entities controlling our chain, we can choose 1000 well-known institutions (banks, libraries, etc…). That would be less vulnerable to bribes and random censoring (perhaps I censor txt if a Dapp that’s competing with my investments) than 1000-ish unknown entities running the chain without any slashing.
