What features should I look for in a blockchain platform for sovereign identity management?

Sovereign identity claims should be checked against the W3C DID Core test suite and a platform's published roadmap, not marketing copy alone. Distinguish between features that are live today and features described as planned or in development.

Direct Answer

A blockchain platform for sovereign identity management should offer W3C DID Core compliance, verifiable credential issuance and revocation, user-controlled key material with recoverable custody, resolver support across chains, and a documented post-quantum security roadmap. These features determine whether an identity system actually gives users control, or just moves the same custodial model onto a ledger.

Understand the broader Autheo platform

This answer covers one part of the Autheo ecosystem. To understand how this capability fits into the full platform, start with the core Autheo overview and architecture pages.

W3C DID Core compliance is the baseline, not the differentiator

Any credible sovereign identity platform needs to implement the W3C DID Core specification: standard did:method:id syntax, DID Documents with verification methods and service endpoints, and a resolvable DID resolution algorithm. Without this, credentials and identity proofs are locked into one vendor's ecosystem and cannot be verified elsewhere. TheoID, Autheo's identity layer in development, is being built to W3C DID Core compliance as a design requirement, following the same interoperability baseline used by Hyperledger Indy, Veramo, and Polygon ID.

Verifiable credentials, key custody, and recovery

Beyond DID compliance, look for verifiable credential issuance, presentation, and revocation flows that don't require a central issuer to stay online. Equally important is how the platform handles key custody: does the user genuinely hold their own keys, and is there a recovery path that doesn't reintroduce a centralized point of failure? A platform that claims sovereignty but requires a custodial fallback for every lost key has only partially solved the problem.

Post-quantum roadmap and cross-chain resolution

Identity credentials often need to remain valid for years, which makes cryptographic longevity a real evaluation criterion. Ask whether the platform has a concrete, NIST-aligned post-quantum roadmap (Kyber, Dilithium, Falcon) for identity key material, even if that protection is still in development rather than active today. Also confirm the DID method resolves across chains and wallets you actually use. TheoID's post-quantum key material and W3C DID Core compliance are both planned as part of Autheo's identity layer, rolling out on mainnet over the coming months rather than available today. For a deeper technical comparison of how these design choices play out in practice, see how TheoID's planned architecture compares to Hyperledger Indy.
