TRANSACTION EXECUTION METHODS, NODES, AND SYSTEMS IN BLOCKCHAINS

Resumen de: US2025335915A1

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.

Resumen de: US2025328876A1

Digital payment systems and methods leveraging optical tones, blockchain technology, and neuromorphic computing to enhance transaction security and flexibility are disclosed. By initiating transactions with unique optical tones generated through mobile IoT applications, payment instructions are encoded into visually encrypted signals, ensuring high security from the outset. Multi-Factor Authentication (MFA), including advanced facial recognition via Convolutional Neural Networks (CNNs), authenticates users, while Spiking Neural Networks (SNNs) process and filter the optical tones, focusing on pertinent transaction details. The system utilizes blockchain oracles and smart contracts for validating transactions and automating the execution of payment instructions, respectively. A novel aspect of this invention is the ability to generate custom payment tokens, either embedded within optical tones or as separate entities, to facilitate specific transactions. This approach not only significantly enhances the security of digital payments but also introduces unprecedented flexibility in managing financial transactions, setting spending limits, and executing recurring payments.
