Abstract
A method for delivering encrypted data through a blockchain with limited transferability includes: receiving, by a receiver of a blockchain node, a transfer submission including at least a transfer token, a recipient address, and an encrypted data message; determining, by a processor of the blockchain node, a number of past transfers for the transfer token in a blockchain associated with a blockchain network that includes the blockchain node; validating, by the processor of the blockchain node, that the transfer token is eligible for an additional transfer based on at least the number of past transfers; generating, by the processor of the blockchain node, a blockchain data value including at least the encrypted data message, the transfer token, and the recipient address; and transmitting, by a transmitter of the blockchain node, the generated blockchain data value to one or more additional nodes included in the blockchain network.
