Distributed Ledger Workgroup

Business Intelligence, timeliness and efficiency are important to MLS participants.  Whereas the RESO Web API provides a signaling mechanism and the RESO Data Dictionary provides elemental definition, lifecycle events allow information to be consumed in a more natural form.  The purpose of the RESO Distributed Ledger Workgroup is to identify and document property lifecycle events. These events could be recorded in a distributed ledger by the industry participants to support accountability, provide instant notifications and identify rules/patterns that are valuable to real estate professionals. The catalog will use RESO Data Dictionary fields wherever possible and utilizes the RESO Web API wherever possible. The Workgroup will work closely with other RESO workgroups to maintain alignment with their work.
