The Challenge

The various local and state associations are independent corporations working together to deliver programs under a Code of Ethics that is over a hundred years old. There is an existing centralized database containing members’ billing information.

Engagement information such as volunteerism, professional development and committee service is not shared. While sharing member engagement information is essential, it is difficult to get 1200 organizations to agree to contribute and relinquish control of their data to a single database.

The Solution

NAR used IBM's Hyperledger Fabric to build the REALTOR® Association Blockchain (nicknamed BlockR), a blockchain-based tool for recording and sharing information about member engagement across the nation’s realtor associations.

This is possible because Hyperledger blockchain fabric is an encoded digital ledger that is stored on multiple computers in a private network. It comprises data records, or “blocks.” Once these blocks are collected in a chain, they cannot be changed or deleted by a single actor; instead, they are verified and managed using automation and shared governance protocols.

Operational Impact
  • [Data Management - Data Accuracy]
    Ensures accuracy and security by keeping good records across all of the association's systems, working collectively, but are not depend on (or be exposed to failures in) partners’ systems.
Quantitative Benefit
  • Searching for member engagement now takes seconds, where it used to take hours of emails and phone calls. The pilot was developed by six associations and included contributed data from an additional four associations. In the week following the presentation of the pilot in March 2018, 51 associations asked to be part of it.
