Abstract

A system and apparatus for data confidentiality in a distributed ledger are disclosed. The system and apparatus preserve qualities of distributed ledgers, such as transparency, integrity, and redundancy, while also providing confidentiality, scalability, and security not previously available in distributed ledgers. The system includes a data confidentiality module that exploits a trusted execution environment for both transaction processing and key synchronization. The apparatus accessing the distributed ledger provides for new nodes joining the network, sending transactions to the ledger by existing nodes, securely processing the transaction using the trusted execution environment, securing transmission to the logic layer for application of business logic, reading and writing data to local storage, and reading encrypted transactions.
