Claim 8:
9. A system for processing cryptographic currency transactions through user-based blockchain ledgers, comprising:
a blockchain network;
a plurality of additional nodes included in the blockchain network;
a first computing device; and
a blockchain node in the blockchain network, wherein the blockchain node is configured to
receive, from the first computing device, a new cryptographic currency transaction including (i) one or more unspent transaction outputs and (ii) a sender public key,
identify a sending blockchain associated with the sender public key, where the sending blockchain is comprised of a plurality of blocks including one or more blocks including the one or more unspent transaction outputs,
validate the sending blockchain by generating a hash value using the sending blockchain and comparing the generated hash value to a historic sender hash value associated with the sender public key, and
generate a new sender hash value by hashing a combination of the sending blockchain and the new cryptographic currency transaction.
