BLOCKCHAIN TRANSACTION CONTROL BASED ON PRIVATE KEY MANAGEMENT

摘要

A wallet management apparatus for blockchain transaction control based on private key management is provided. The wallet management apparatus includes a memory that stores smart contract information associated with each user of a plurality of users. The wallet management apparatus includes circuitry that receives a first request for a first transaction on a blockchain network from a first administrator device associated with a first administrator. The circuitry retrieves first token information from the first request. The first token information indicates an association between the first administrator and a first user. The circuitry validates the first administrator based on the first token information and the smart contract information. The circuitry extracts a first private key associated with a first user device of the first user based on retrieved first token information and the validation and controls the first transaction on the blockchain network based on the first private key.
