Abstract: A system, device and method of confidential secure custodial and/or ownership transfers of asset between entities implemented via an open registry, wherein a ledger securely records each of the transactions utilizing shielded or proxy data state such that information about the transactions cannot be gleaned from the ledger despite the accessible nature of the records on the open registry.

Abstract: A system, device and method of confidential secure custodial transfers of asset between entities utilizing transaction agents implemented via a distributed ledger (e.g. a blockchain). In particular, the transaction agents securely record each of the transactions on the ledger utilizing obfuscated or proxy data state such that information about the transactions cannot be gleaned from the ledger. In particular, the transaction agents are able to enforce business rules of the system by requesting zero-knowledge proofs from participants to the transaction (e.g. sender and recipient) in place of actual data for the transaction. The zero-knowledge proofs are able to be designed to prevent an observer of the distributed ledger from determining any information of the transaction that is taking place.
