摘要： A system and method for oblivious information retrieval are disclosed. A particular embodiment includes: a plurality of network nodes in data communication with each other via a network, each network node having a secure processing enclave, the enclave configured to include: at least one isolated memory device, processing logic isolated from operating system (OS) calls, and a remote attestation capability; and a view node in data communication with the plurality of network nodes and a transaction ledger, the view node including an account index horizontally scaled across a plurality of computing devices, the view node further configured to receive a transaction and a corresponding account hint, to decrypt the account hint, and to add a row corresponding to the transaction and the account hint to the account index.
