Platform for multi-party digital records using distributed ledger system

One or more non-transitory computer-readable storage media coupled to one or more processors and having instructions stored thereon which, when executed by the one or more processors, cause the one or more processors to perform operations comprising:

• providing a first transaction hash code comprising a digital representation of a digital record between a first peer and a second peer within a digital records platform,
• the digital records platform provided by the first peer as a host peer, and
• the first transaction hash code being generated based on a hash tree, and hash codes that are generated based on one or more documents underlying the digital record, hash code of the one or more documents at least partially represented as nodes on the hash tree and the first transaction hash code being a root hash of the hash tree;
• receiving one or more edits to at least one document from the second peer;
• in response to the edits to at least one document from the second peer, updating the first transaction hash code to provide:
• a second transaction hash code based on the first transaction hash code and the hash tree to reflect changes in the at least one document, the hash tree comprising hash code of the at least one document with edits being as one of the nodes on the hash tree, the hash code of the at least one document with edits being updated based on the edits, and
• a transaction hash history comprising the first transaction hash code and the second transaction hash code;
• receiving approval of the digital record from each of the first peer and the second peer;
• and
• executing a consensus protocol by a notary service of a third node to update transaction objects across the first node and the second node,
• the updating indicating that the transaction objects are consistent, and
• the executing a consensus protocol performed in response to the receiving the approval of the digital record.
