Claim 4:
5. A method for ensuring precedence for the processing of a blockchain transaction to prevent loss of cryptographic currency, comprising:
storing, in a memory of a blockchain node, a blockchain, wherein each block in the blockchain includes at least one blockchain data value including a reference to a sending blockchain wallet and a reference to a recipient blockchain wallet;
receiving, by a receiver of the blockchain node, from a computing device, a new blockchain transaction including a digital signature of a first blockchain wallet and a recipient address of a second blockchain wallet;
generating, by a processor of the blockchain node, a precedence blockchain transaction including the first blockchain wallet, the second blockchain wallet, and a zero or nominal transaction amount;
transmitting, by a transmitter of the blockchain node, a first new block to a plurality of additional blockchain nodes, the first new block including the precedence blockchain transaction;
receiving, by the receiver of the blockchain node, a confirmation message from the computing device;
subsequent to receiving the confirmation message, generating, by the processor of the blockchain node, a new block including at least one new blockchain data value, wherein the at least one new blockchain data value includes the new blockchain transaction.
