Abstract
A single-tier blockchain-based method for document transformation and accountability via different node types is provided. Document templates relating to a transfer of real property are maintained. Each template includes form elements each associated with a data field identifier. A subset of the document templates are collected as transaction documents for a transaction of a real property transfer. The form elements of the transaction documents are populated with received data values via the data field identifiers of the form elements. Compliance checking is performed on the populated data values of the transaction documents. A cryptographic hash of the transaction documents is provided to a network of nodes, which includes nodes that store different types of data related to the transaction documents. The cryptographic hash of the transaction documents is committed to a blockchain stored by one or more of the nodes in the network.
