Settlement is closed. Solvency is not.

No serious participant settles where its book is visible to a competitor. Positions and flows are not published.

What leaves the system is a proof that collateral covers obligations, without revealing whose collateral it is or how large any position is.

The two properties, separately

• Confidentiality. Individual positions, sizes and counterparties stay closed.
• Verifiability. The aggregate claim, that posted collateral covers outstanding obligations, is checkable by anyone at any time.

These are not in tension. The proof is about the aggregate, not about the members.

Against the traditional baseline

A traditional clearing house publishes solvency on a quarterly cadence, audited after the fact, and participants take it on trust between reports. Continuous verifiable proof is a strictly stronger guarantee than a quarterly attestation, and it is the thing onchain infrastructure can offer that the incumbent structure cannot.

What is deliberately not claimed

• Not a claim that a proof removes the need for collateral. It does not. It shows the collateral is there.
• Not a claim of privacy against the protocol itself. The clearing layer necessarily knows the obligations it novates.
