Solidus Identity
Solidus Identity vs walt.id
walt.id gives you a full OID4VC issuer/wallet/verifier stack to run yourself. Solidus gives you the same standards plus the network and the KYC issuer already running underneath.
Solidus is a public testnet: no mainnet, no token, no external audit, and no paying customer. Every claim below is checkable; none of them are a substitute for the certifications an incumbent already holds.
What walt.id does better
- 45,000+ developers, per walt.id's own claim — Solidus has no published developer-adoption number to set against it.
- Named enterprise deployments: Accenture, IBM, Mastercard, Air NZ, and EU institutions, per the brief.
- A 20-million-citizen production rollout in Thailand — a national-scale reference Solidus cannot match today.
- A free, zero-cost OSS core has already won a real share of developer mindshare in the SSI space, per the brief.
Where Solidus is different
- did:solidus is registered in the W3C DID Method Registry and resolves on a live testnet — walt.id has no L1 or chain-anchored trust of its own, per the brief.
- Native KYC issuance via verify.solidus.network in the same stack, which the walt.id brief does not credit it with.
- Apache-2.0 protocol access without walt.id's gated Cloud tier for the hosted path.
