Abstract: A method for propagating survival of cryptographic currency after inactivity over a predetermined period of time in a blockchain through the use of smart contracts includes: receiving a propagation request that includes unspent transaction output addresses, a digital signature, and a recipient address; generating a smart contract that is configured to self-execute after a predetermined period of time to initiate transfer of cryptographic currency from the output addresses to the recipient address; submitting the smart contract to a node in a blockchain network for addition to the blockchain; monitoring for new blockchain transactions involving any of the unspent transaction output addresses; generating a new smart contract to update the unspent transaction output addresses based on new blockchain transactions; and submitting the new smart contract to a node in a blockchain network after updating.

Abstract: A method for dynamic license plate renumbering includes: identifying, by a processing device of a processing server, a new plate number for a dynamic license plate; storing, by the processing server, the identified new plate number in a data entry with a vehicle identifier associated with the dynamic license plate; transmitting, by a transmitter of the processing server, the identified new plate number to the dynamic license plate; and displaying, on a display device of the dynamic license plate, the new plate number.
