In the context of decentralized technology there is a lot of gaps to bridge, as they are all context-specific
What we lack on Nostr is effective consensus mechanisms. When we can achieve decentralized consensus, we can achieve everything else.
The foundation of a Web of Trust is lists. Lists are the building block. On Nostr, this is NIP-51, which is why we now have sets of lists, kind 30000.
Even a few hours ago Pablo and Fiatjaf were considering wiki relay list management with yet another NIP-51 kind, and Pablo noted how NIP-51 could become bloated, assuming I interpreted their conversation correctly. I believe this trend will continue until NIP-51 lists become the foundation of the protocol. Sets of lists was an important step.

The rest isn't easy, but it will be rewarding.
