Patent ID: 11928673

Abstract:
Systems and methods for authorizing a blockchain transaction. A verification network receives a transaction request for the blockchain transaction from a payer device including a first signature generated by a first private key associated with a payer. The verification network broadcasts a verification request to verification system(s) which assess pre-agreed threshold parameters. If the parameter(s) are satisfied, at least one verification system perfects the transaction by generating a second signature using a second private key, and broadcasts the transaction to the blockchain network. If the parameter(s) are not satisfied, verification offer(s) from among the verification system(s) including the second signature(s) are used to prompt the payer device to confirm the blockchain transaction by selecting at least one of the offer(s). The verification network receives selected offer(s) from the payer device and broadcasts the transaction to the blockchain network, in accordance with the selected offer(s) and the transaction request.
