Abstract
A blockchain-based method for document transformation and accountability is provided. Document templates for real property transfer are maintained. Each template includes data fields. Some of the document templates are collected as transaction documents for a transaction for the property transfer. The data fields are populated with received data values. Compliance checking is performed on the populated data values. The checked transaction documents are provided to a network having a first tier of network nodes and a second tier of supernodes. One of the supernodes is selected to validate the transaction documents. The validated transaction documents are added to a ledger of transactions. A hash of the validated transaction documents is transmitted to the first tier. One of the network nodes is selected to commit the hash to a blockchain of the first tier. The hash is committed to copies of the blockchain.
