Claim 12:
13. A system for ensuring precedence for the processing of a blockchain transaction to prevent loss of cryptographic currency, comprising:
a blockchain network,
a blockchain node in the blockchain network, the blockchain node including
a memory storing 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,
a receiver receiving, 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,
a processor of the blockchain node generating a precedence blockchain transaction including the first blockchain wallet, the second blockchain wallet, and a zero or nominal transaction amount, and
a transmitter transmitting a first new block to a plurality of additional blockchain nodes in the blockchain network, the first new block including the precedence blockchain transaction, wherein

the receiver receives a confirmation message from the computing device, and
subsequent to receiving the confirmation message, the processor generates 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.
