Visa builds blockchain-based trusted execution environment 21 hours ago by Miranda Wood Today, Visa has published a paper claiming to describe the first trusted execution environment (TEE) which allows fair, policy-compliant computation. A TEE partitions off some of a processor so it can work on sensitive data and keep it safe. Unlike other TEEs, however, LucidiTEE can protect against bad actors manipulating outputs by using a shared ledger of computation history. In testing, permissioned blockchains, including Hyperledger, were used as the ledger. The paper from Visa’s researchers introduced LucidiTEE as: “the first system to enable multiple parties to jointly compute on large-scale private data, while guaranteeing policy-compliance even when the input providers are offline, and fairness to all output recipients.” TEEs, such as Intel SGX, are good at enabling efficient and secure computations on large encrypted datasets. But even though...
