Farcaster

All these Farcaster tipping currencies are basically sovereign rollups using Farcaster as a DA layer with trusted bridges to an L2.

An odd consequence of this is that since Farcaster does not produce a canonical ordering, tipping is subject to double spends until the token is "bridged" to the L2.

many undesirable consequences from the lack of verifiable ordering including:
-can backdate casts
-hubs automatically purge any and all casts from previously valid signers that are revoked
-cannot verify or compose with casts onchain without trusting the signer

We are thinking a lot about this @witness
