I've been digging around for a while... What is this "Attestation Layer" of the Sign Protocol? At first I thought - well, another system for saving data. But later I relized, it's not about data... it's actually about proof. I mean... someone here not just storing information but making a claim - that this infrmation is true - and locking it with a cryptographic signature. This place is important, because here trust is moving away from the entity and moving to proof. But the real game is in the schema. It sounds dry... but the schema defines - how which data kept, which will be considered valid. This is where a little power shift occurs. Because the one who controls schema indirectly decides which truth system will be entered. Then the attestation record - once created, is immutable. The good thing is, no one can change it later. But the real world is messy... what if the wrong data? What the context changes? Then it becomes rigid. The storage model is pragmatic - on-chain security, off-chain salability, hybrid balance. But trade-off is clear - cost vs availability. The ZK part is interesting - proof without full data. But adoption hard, dev complexity real. To me it's not a "solved problem"... but an "important attempt".
Finally -
Sign is not managing data... they are trying to "trust encode". it works - the impact is big. If it dosn't - it will remain as another infrastructure layer.🚀
