yup. the architecture that most blockchains use was designed originally just as a failover replication strategy that was resistant to 1/3 *malicious* replicas. it even says so in the 1999 practical byzantine fault tolerance paper, that's why if you dig a little way into most blockchain whitepapers the 2/3 majority comes up. (i think that it's interesting how it aligns with the vote scheme of most senates).
they are not intended to be used outside of the centralized context. they just resist 1/3 malicious particpants. that's too optimistic for broad decentralized systems. this is why it's irrelevant to the nostr style database/subscription/relay design. the relay controls access by cryptographic signatures (most nostr devs don't get taht part), they store data that is self-authenticating, and based on the prior two they can act as rendezvous for arbitrary communications.
