       | I'm working on software (member.cash) that bridges multiple

       | 
       | Compared to the others, Nostr is optimized for innovation - it is
       | easy to build new features on top and we'll see a lot of growth
       | and evolution because of that. I really like that about it.
       | 
       | The problems I see with it right now are 1. Timestamps are easily
       | forgeable 2. Difficult to control spam 3. Little incentive to run
       | relays 4. Difficult to search the whole network
       | 
       | There are ideas on how to solve all of the problems, like POW on
       | messages, like super relays(basically a mempool), there's a NIP
       | for timestamps.
       | 
       | My guess is that it will evolve towards something that looks a
       | lot like a blockchain. Decentralized Social is one of the few
       | places where a blockchain actually makes sense. This will be
       | interesting because the founding group is ideologically opposed
       | to using a blockchain for anything but the holy BTC.
