Validity Verification of Encrypted Transaction Amounts in Blockchain

This research suggests an authentication system for encrypted payment amounts using zero-knowledge proof and encryption algorithm, with the goal of enhancing security and trustworthiness of blockchain transactions. The system effectively processes large-scale transaction data by incorporating functional modules like data input, verification, and output in a modular system architecture. Results from experiments demonstrate that the system achieves a verification precision of 99.8% when handling transaction data sets of various sizes, with processing time increasing proportionally as the transaction size grows, indicating excellent scalability. This research offers effective options for financial transactions, supply chain management, and digital asset management, guaranteeing the security and integrity of transactions while enhancing transparency and traceability in multi-party interactions. Furthermore, by examining various usage situations, the system showcases its wide range of potential and value in practical use. This research introduces fresh technological methods for verifying security in blockchain transactions and establishes a basis for future studies and implementation.
