Blockchain-based system and method for listing document transformation and accountability

A blockchain-based method for listing document transformation and recordation, comprising:

• maintaining a library of listing documents relating to a real estate listing, each listing document comprising a plurality of data fields, wherein each data field is associated with a data field identifier and with process logic;
• identifying a set of listing documents selected from the library of listing documents for a listing of property;
• receiving from at least one user over a time period data values in at least one of the data fields of one or more of the listing documents in the set;
• dynamically updating via the process logic at least a portion of the data fields within at least one of the listing documents in the set with the received data values based on the data field identifiers associated with the data fields in which the received data values were received;
• receiving disclosure information regarding the property;
• adding further listing documents to the set of listing documents based on the received disclosure information to form a set of active listing documents;
• applying a set of listing compliance rules to the set of active listing documents to determine a compliance of the listing documents in the set with the rules;
• recording the active listing documents as a data block, further comprising:
• providing the data block to a tier of supernodes;
• adding the data block to a ledger of transactions via one of the supernodes;
• storing a copy of the data block on each of the supernodes;
• transmitting an immutable record of the data block from the supernode to a tier of network nodes;
• and
• committing the immutable record of the validated transaction documents to a blockchain of the first-tier via each of the network nodes.
