If adopted, the system would allow chess players to independently manage their identity and credentials across all chess platforms and organizations with a single decentralized ID, and one login credential for everywhere they play. They could then easily "port" their identity, achievements, records of play, rankings, and rewards across online chess platforms, as well as seamlessly from the digital world to in-person games and tournaments. This provides them with a much easier way to prove their identity, no matter their status or documentation; it would also reduce tournament application times significantly. Chess organizations would then be able to welcome even more players to their competitions, including those who have built their chess career solely online, as well as players who have previously only competed in tournaments held by other organizations.
