Abstract
An example operation may include one or more of receiving a blockchain transaction that comprises a state reference to an unspent transaction output (UTXO), determining whether the UTXO is included within a first subset of transactions on a blockchain ledger based on a zero-knowledge (ZK) proof included in the state reference, determining whether the UTXO is included within a second subset of transactions on the blockchain ledger based on a hash value included in the state reference, and in response to a determination that the UTXO is not included in either of the first and second subsets of transactions, committing the blockchain transaction including the state reference to the blockchain ledger via a blockchain peer.
