I stopped looking at Sign as a token and treated it like a system constraint.
Two primitives only: schemas (rigid templates) and attestations (signed, append-only state).
Flow is deterministic:
issue → sign → anchor (multi-chain) → index → verify (schema + sig + revocation).
Hybrid data model:
commitment on-chain, payload off-chain / Fabric namespace.
Execution splits:
public rails = composability + liquidity
private Fabric X = 100k+ TPS, Arma BFT, policy isolation
ZK layer (Groth16 / Plonk / BBS+) compresses truth:
prove eligibility without exposing state.
But the system tightens under scale:
No edits. Only supersede + dispute.
Revocation = new writes.
Indexer latency becomes regulatory bottleneck.
Bridge is the real system:
public ↔ private sync = trust surface
Central bank controls:
orderers, limits, kill switches
So the outcome is clear:
This isn’t trustless infra.
It’s governed evidence at scale.
Schemas lock decisions early.
ZK enforces minimal disclosure.
Dual-layer forces policy at every bridge crossing.
Nothing breaks at scale.
The constraints just become visible.
