Abstract: A single-tier blockchain-based method for document transformation and accountability is provided. Document templates relating to a transfer of real property are maintained. Each template includes a plurality of form elements each associated with a data field identifier. A subset of the document templates are collected as transaction documents for a transaction regarding the transfer of real property. 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 single tier of network nodes. The cryptographic hash of the transaction documents is committed to a blockchain copy stored by one or more of the network nodes in the single tier and the transaction documents are stored.

Abstract: A system and method for document transformation and compliance are provided. Document templates are maintained and each template includes data fields each associated with a data field identifier. Data values are received in one or more of the data fields of at least one document template. The data values are associated with the data fields into which the data values are received via the data field identifiers for those data fields. A property address is received and a set of compliance rules is identified. A subset of the document templates are retrieved as active documents for a transaction of the property based on the identified rules. The active documents are populated with those data fields that are associated with the linked data values via the data field identifiers. Compliance checking of the populated data values in the active documents is performed using a compliance rule set.

Abstract: A method for listing document transformation and recordation is provided. Documents relating to a real estate listing are identified and each document includes data fields associated with data field identifiers. A data value is received from a user in at least one of the data fields. A data model includes the data values received from the user and the data field identifiers of the data fields for which the data values are received is generated. The data fields associated with data field identifiers that match the data field identifiers of the data fields in which the data values are received are identified and populated with the data values. One or more correctness rules to be applied to the populated data fields of the documents are identified and applied to the documents by verifying that the data values populating the data fields are verified by one or more authoritative sources.

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.

Abstract: A method for listing document transformation and recordation is provided. Listing documents are selected from a library for a property listing. Data values are received via at least one of the listing documents. Relevant data fields within at least one listing document is updated with the received data values. Disclosure information regarding the property is received and further listing documents are added to the listing documents based on the disclosure information to form an active document set. Listing compliance rules are applied to the set of active documents to determine compliance. The active documents are recorded as a data block and provided to a tier of supernodes. The data block is added to a ledger of transactions via one of the supernodes. A copy of the data block is stored on each supernode. An immutable record of the data block is committed to a further tier of nodes.
