Snapchain is launching soon! It's a blockchain like system that will be 10x - 100x faster than hubs and much more reliable when syncing between Farcaster apps. If you don't run a hub, no action is needed. If you do run a hub you will need to: - Set up a Snapchain node before Mar 29th - Cut over to reading / writing from your node before Apr 12 - Shut down your hubs after Apr 15th More details in next cast.

No, that's something we need to work on post launch

Might be able to move them to Snapchain and get zero cost signers

hmm, then I would like to nudge against this, censorship resistance for key revocations/rotations I think is important for decentralized identity. BSky currently has this problem with did:plc, @edmundedgar.eth has done some good thinking here. maybe you can add signers, but revoking them happens onchain? but L2s are so so cheap already, I question the need for free-signer-adding given you have to pay for an FID anyway & adding signers doesn't happen that often https://warpcast.com/edmundedgar.eth/0xe8fb71b9 https://warpcast.com/edmundedgar.eth/0xf49b6959

Also keeping ed25519 canonically on OPMainnet allows signed messages to be validated in smart contracts easily, even on different L2s with message passing. If new signers are only on Snapchain, there would need to be some sort of oracle bridge for smart contracts to know about new signers, unless Snapchain were to have it's own "L3" construction.

The $ cost benefit of doing this is for apps, not the end user Apps should sponsor signers anyway, so their end users don't have to pay for each signup, but now you have to manage hot wallet balances / Neynar balances The other benefit is that latency can go down. Waiting for a tx to be confirmed is painful UX
