Abstract
An improved computational privacy based approach is proposed to allow for a blockchain privacy enabled transaction protocol for processing distributed ledger transactions of a specially configured blockchain smart contract, the approach describing a cryptographic process, along with a corresponding apparatus and computer program products using a pair of specialized UTXO merkle tree data structures, authentication nullifiers based on zero-knowledge proofs and sets of public-private key pairs. The process includes storing a transaction amount as UTXOs into a first merkle tree data structure and confirming the transaction by claiming ownership using private tokens over the UTXOs in the first merkle tree data structure and moving the UTXOs to a second merkle tree data structure for redemption.
