Cellula ID (.cell) vs d.id (.bit)

The short answer Question Answer Are both on Nervos L1? Yes. Both store names as cells on Nervos CKB mainnet. .bit added RGB++ / DOBs compatibility in July 2024 so it can be managed from Bitcoin and EVM wallets, but the names still live on CKB. Is d.id still working? Yes, the registration app works. On Sep 27, 2026 it quoted a 5+ character name at $5/year and a 4-character name at $160/year. Is d.id active? Mostly quiet. The last X post was Dec 31, 2025 ("Happy New Year"). The last blog post was July 2024. The last public GitHub commit was March 17, 2026 (small fixes). No shutdown has been announced. Biggest Cellula advantages Short names 8x cheaper, 1–3 character names on sale, Lightning Address, Fiber, signed payment requests, and a post-quantum (SPHINCS+) ownership option. Biggest d.id advantages Brand recognition, many existing users and integrations, login with many non-CKB wallets, and names already tradeable as DOBs. 1. Same foundation, different design goals d.id (.bit) started in 2021 as DAS (Decentralized Account Systems), was renamed .bit in March 2022 and d.id in September 2023. It raised a $13M Series A in 2022. Its goal is a cross-chain identity : one account that people on Ethereum, BNB Chain, Polygon, TRON or Dogecoin can register and manage with the wallet they already use . Nervos makes that possible because CKB can check other chains' signatures. Cellula ID (.cell) went live on mainnet on September 21, 2026 . Its goal is a payment identity : one name that people can pay on several rails, with ownership that can outlast today's cryptography.
