Blockchain transaction execution is described. The blockchain includes a first node and a second node, the first node includes a trusted execution environment (TEE). The first node executes a first transaction in the TEE to obtain a first execution read-write set of the first transaction, and signs the first execution read-write set by using a private key in the TEE to obtain a first signature, where the first execution read-write set includes a first execution read set and a first execution write set. The first execution read-write set and the first signature is sent to the second node. The second node verifies the first signature by using a public key corresponding to the private key, verifies the first execution read set after the verification on the first signature succeeds, and stores the first execution write set as an execution write set of the first transaction when the verification succeeds.

Approaches disclosed herein provide digital payment processing that integrates cryptocurrency transactions with traditional banking systems through the use of, for example, blockchain technology in a streamlined digital payment process. As an example, a digital payment processing system may integrate cryptocurrency with exchanges and banking systems via APIs. Such integration allows for the determination and use of real-time exchange rates, as well as almost immediate transfer of funds between cryptocurrency and fiat (traditional) or other such currency. By automating the exchange process and connecting directly to financial institutions for instant fiat settlement, such approaches can effectively avoid the usual delays of blockchain (or other distributed ledger-based) confirmations. Such a system may also utilize other technologies for facilitating a faster transaction process, such as off-chain solutions or layer-2 scaling solutions.
