Legacy settlement systems partition private information but are vulnerable to settlement fails. A token system with dynamic ownership representation, or a dynamic ledger, can be designed to achieve both, as long as it employs a protocol that enforces two restrictions: programs must be immediately implemented and must involve transactions based on verifiable ...
