Method and system for linkage of blockchain private keys

Abstract:

A method for processing redundant blockchain transactions for linked wallets includes: storing blockchain data associated with a blockchain including a plurality of blocks, each block including a block header and blockchain data values, each data value corresponding to a processed blockchain transaction; receiving a new blockchain data value including an input transaction, recipient address, and transaction amount; confirming each input transaction based on a corresponding blockchain data value; identifying a plurality of blockchain wallets linked to the recipient address, and, for each wallet, an additional recipient address; generating a mirror blockchain data value for each linked wallet including the input transaction, transaction amount, and the additional recipient address identified for the respective linked wallet; and transmitting the new blockchain data value and each mirror blockchain data value to one or more nodes in a blockchain network associated with the blockchain.
