Systems and methods for providing data privacy in a private distributed ledger

A method for providing data privacy in a private distributed ledger, comprising:

• receiving, by a node in a distributed ledger network, a block comprising a first transaction and a second transaction written to the distributed ledger;
• determining, by a node computer processor, that the first transaction is a private transaction;
• communicating, by the node computer processor, a node public key and a transaction hash digest for the first transaction to a transaction key manager for the node;
• receiving, by the node computer processor, an encrypted transaction payload for the first transaction;
• decrypting, by the node computer processor, the encrypted transaction payload, the transaction payload comprising contract code associated with the first transaction;
• executing, by the node computer processor, the contract code associated with the first transaction;
• determining, by the node computer processor, that the node is not a party to the second transaction;
• and
• skipping, by the node computer processor, execution of contract code associated with the second transaction;
• wherein the node computer processor determines that the first transaction or second transaction is a private transaction based on a sentinel byte associated with first or second transaction.
