Solidus Network
Solidus vs Concordium
Concordium is our closest framing rival — their tagline is almost ours. The real difference is not the pitch: it is that our method is registered in a public registry, our products are reachable, and our standards are someone else’s.
Where Solidus is different
- did:solidus is registered in the W3C DID Method Registry (PR #713, merged 2026-07-04). Concordium has no registered DID method.
- Solidus is a DIF Associate Member — the logo is on identity.foundation. Concordium is not.
- Open protocol with 7 reachable products and a public SDK on npm; Concordium is a closed protocol.
- Composition over invention: ~44 open standards, exactly one new artifact. The answer to "another identity L1?" is a bill of materials, not a claim.
