Abstract
A method of securing media-based transactions and contracts on a distributed ledger network comprising receiving a first media file, obtaining a fingerprint of the first media file, generating a non-cryptographic hash value for the fingerprint of the first media file, generating a block for the distributed ledger network comprising a block header comprising previous hash, a state root hash, a receipts root hash, and a transaction list root hash, defining block header hashes, recording the non-cryptographic fingerprint hash value for the fingerprint of the first media file to the block and recording the block to the distributed ledger network.
