摘要： A system and method for providing auxiliary curve cold storage are disclosed. A particular embodiment can be configured to: prepare a base cryptocurrency protocol transaction in a secure transaction network including a consensus network, a ledger, and a network node in data communication with the consensus network, the ledger, and other network nodes in the secure transaction network via a data network; generate a transaction output signature (txo-sig) by signing a hash of a source transaction output (source-txo) with a certified hardware security module (HSM) private key; submit the base cryptocurrency protocol transaction and the txo-sig to the consensus network via the network node of the secure transaction network as a deposit transaction; create a ristretto point (rptxo) from a hash of an HSM public key, the source-txo, and the txo-sig; and replace the source-txo with the ristretto point (rptxo) in the ledger of the secure transaction network.

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.
