ICANN draft rules complicate Web3 TLD integrations

ICANN’s latest draft guidelines for integrating alternative naming systems with new generic top-level domains (gTLDs) could force Web3 namespace operators to overhaul their existing registries or abandon plans to secure matching domains in the 2026 application round. The report, published this week by a technical study group, outlines requirements that may conflict with the decentralized principles of blockchain-based naming systems while adding significant operational and financial burdens for applicants.

What the draft requires

The draft report, produced by the Technical Study Group on gTLD Integrations with Alternative Naming Systems, mandates that any registry operator applying for a TLD matching an existing Web3 namespace must enforce strict synchronization between the two systems. Under the proposed rules, domains registered in the alternative root would be automatically reserved in the ICANN-managed DNS root, accessible only to the same registrant. This effectively eliminates the anonymity often touted as a core benefit of Web3 naming systems, as registrants would need to verify their identity to claim matching DNS domains.

Registry operators would also be required to maintain control over the Web3 namespace to ensure bidirectional synchronization. If a domain is suspended in either system—whether due to trademark disputes, abuse complaints, or other enforcement actions—the corresponding domain in the other system must also be suspended. This requirement could create technical and governance challenges for Web3 platforms, which often rely on decentralized ownership models that limit centralized control.

Why compliance may be costly

For Web3 namespace providers already operating alt-root systems, the draft rules present a dilemma. To comply, they would need to assert centralized control over their namespaces—a move that could alienate users who value decentralization. Additionally, the requirement to reserve domains already registered in their systems could prevent the sale of high-value names in the DNS root, reducing potential revenue. The financial and technical costs of implementing synchronization mechanisms, identity verification, and enforcement protocols may outweigh the benefits of securing a matching TLD.

The draft also raises questions about the legal and operational feasibility of suspending domains in decentralized systems. Many Web3 platforms lack the infrastructure to enforce suspensions, and retrofitting such capabilities could require significant development effort. Furthermore, the requirement to sync suspensions in both directions could create conflicts with existing governance models, particularly for platforms that prioritize user autonomy over centralized enforcement.

What’s next for applicants

With the application deadline for the 2026 gTLD round set for today, prospective registry operators have limited time to assess the draft’s implications. ICANN has urged applicants to review the report and submit comments, though it remains unclear how much weight the final recommendations will carry in the evaluation process. The draft’s emphasis on synchronization and control suggests that ICANN is prioritizing consistency between naming systems, even at the expense of flexibility for alternative platforms.

For Web3 operators, the choice may come down to accepting ICANN’s terms or forgoing the opportunity to secure a matching TLD. Those who proceed will need to navigate the Registry Services Evaluation Policy (RSEP) and potentially undergo additional technical evaluations, adding further complexity to an already competitive application process. The outcome could shape the future of integrated naming systems, determining whether Web3 and DNS roots can coexist or remain fundamentally separate.
