Abstract
The system and method of the present disclosure includes creation and management of audit chains, which are distributed ledgers serving a native translation of non-native statements. The system and method further includes the application of audit chains to zk-audits, in which the provider of a service, e.g., a centralized token exchange, proves correct behavior to its clients without revealing private data.
Claims8
A computer-implemented translation ledger management method applied to a source ledger, the method comprising:
- tracking events in the source ledger by a translation ledger operated by a plurality of translation nodes, wherein the translation ledger is a distributed Byzantine fault-tolerant ledger;
- processing, according to rules of the translation ledger, information within a source event in the source ledger to be appended to the translation ledger, the processing comprising converting at least a portion of information in the source event into a format that is more efficiently processed by a cryptographic proof system than would be processed when in a source ledger format, the processing further comprising replacing non-circuit friendly cryptographic primitives with specified circuit friendly cryptographic primitives;
- appending an output of the step of converting to the translation ledger;
- accessing, by business logic, the appended output on the translation ledger, where the business logic is a zero-knowledge exchange;
- and
- generating, by the business logic, a zero-knowledge proof certifying accordance with a set of claimed business rules.

A non-transitory machine-readable storage medium that provides instructions that, when executed by a processor, cause the processor to perform operations applied to a source ledger, the operations comprising:
- tracking events in the source ledger by a translation ledger operated by a plurality of translation nodes, wherein the translation ledger is a distributed Byzantine fault-tolerant ledger;
- processing, according to rules of the translation ledger, information within a source event in the source ledger to be appended to the translation ledger, the processing comprising converting at least a portion of information in the source event into a format that is more efficiently processed by a cryptographic proof system than would be processed when in a source ledger format, the processing further comprising replacing non-circuit friendly cryptographic primitives with specified circuit friendly cryptographic primitives;
- appending an output of the step of converting to the translation ledger;
- accessing, by business logic, the appended output on the translation ledger, where the business logic is a zero-knowledge exchange;
- and
- generating, by the business logic, a zero-knowledge proof certifying accordance with a set of claimed business rules,
- wherein the step of converting comprises one or more of reformatting and restructuring transaction data from a block associated with the source event in a deterministic manner, then computing a block hash of the transaction data,
- wherein correctness of an output of the step of converting is enforced by a consensus mechanism of the translation ledger.
