- The record includes a version tag and optional fields for contact URIs, text, codes, and asking prices.
- It acts as a discovery layer, not a marketplace; negotiations and transactions remain separate and human-driven.
- Proposed by SIDN Labs to make the domain market more transparent, particularly benefiting owners who are not professional traders.
