So my understanding is each Farcaster hub stores ALL the messages past, present, and future of Farcaster. Will there one day be lighter nodes that only store some? Otherwise, that sounds quite challenging to sustain 🤔. (Also found out Farcaster uses libp2p today, yay!)

I think it‘d be possible to shard. The SMT stores all messages in order (based on the time stamp). And you can split that set in all possible ways to decrease node size.
