@vrypan raises an important point about the tradeoffs of snapchains design. If we only have 10 nodes that can validate messages isn’t that bad for decentralization? 

Let’s start with the problem that Snapchain is solving. Our deltagraph network lets any hub add a new message at any time. As the network grows, failures between nodes increase and delays become inevitable. 

You have to be able to “check” your sync state with a large percentage of the network in a short amount of time and this breaks down quickly. When it does, users will complain about messages moving very slowly between apps, which will make them less likely to use Farcaster, and less likely for apps to be built.
