TL;DR: Blockchain-based identity verification shifts credentials away from centralized databases and toward decentralized record keeping, but it does not remove the governance burden around trust, portability, and key management, according to 1Kosmos. For IAM teams, the real question is which identity controls still hold when proof and storage are distributed rather than concentrated.
NHIMG editorial — based on content published by 1Kosmos: What is Blockchain Verification & Validation?
Questions worth separating out
Q: How should security teams govern blockchain-based identity verification?
A: Security teams should treat blockchain identity as a governed trust layer, not a replacement for IAM.
Q: Why do decentralized identity models still need strong lifecycle controls?
A: Decentralized identity models still need lifecycle controls because portability does not solve revocation, expiry, or accountability.
Q: What breaks when blockchain identity claims cannot be revoked quickly?
A: When blockchain identity claims cannot be revoked quickly, downstream systems may continue trusting stale assertions after access should have ended.
Practitioner guidance
- Define ledger governance before pilot adoption Document who can issue identity assertions, who can validate them, and who can revoke them across the permissioned network.
- Test revocation and expiry across relying parties Confirm that portable identity claims actually expire or withdraw cleanly in downstream systems.
- Treat key recovery as an attack surface Review device binding, backup, and recovery procedures for the credentials used in the blockchain identity flow.

Blockchain identity is not a governance shortcut. Decentralized record keeping can reduce dependence on a single identity database, but it does not replace the controls IAM teams need for issuance, revocation, and accountability. The practical issue is that trust now depends on distributed participation rules instead of a central repository. Practitioners should judge blockchain identity by whether it improves assurance and lifecycle control, not by whether it sounds more resilient.
A few things that frame the scale:
- 79% of organisations have experienced secrets leaks, with 77% of these incidents resulting in tangible damage, according to Ultimate Guide to NHIs.
- Only 5.7% of organisations have full visibility into their service accounts, which is why distributed identity models still need explicit governance and inventory discipline.
A question worth separating out:
Q: What is the difference between blockchain identity and federated identity?
A: Blockchain identity focuses on distributed record keeping and verification, while federated identity focuses on how one system trusts assertions from another. They can work together, but they solve different problems. Blockchain may change where identity evidence lives, but federation still governs how relying parties authenticate and authorize access.
