What to Consider When Evaluating Decentralized Identity?

Decentralized identity is emerging as a specialized segment within Identity and Access Management (IAM), driven by blockchain development and growing public demand for stronger user control over personally identifiable information (PII). Traditional enterprise identity management creates structural risks: organizations become custodians of large “honeypots” of user data that attract attacks, while users cope with too many accounts by reusing passwords, compounding security weaknesses. The rapid growth of uniquely identified IoT devices further worsens siloed identity data and stresses existing models. Alongside technical pressures, public sentiment is shifting toward user-centric and self-sovereign identity, where individuals own and control their identity attributes.

Decentralized identity solutions focus primarily on identity proofing and secure storage/sharing of credentials. In enterprise environments, they can complement Identity Governance & Administration (IGA) and access management for employees, partners, customers, and IoT by enabling verified credential attestations to be reused across organizations while maintaining user ownership. Although these systems often assume continued reliance on traditional access management and lifecycle practices (including federation), they can also present an alternative to federated identity.

Selecting a solution requires defining a clear enterprise use case, with common targets including identity management, customer onboarding, reusable KYC, risk-adaptive passwordless MFA, and privacy-preserving proof of age. Key functional capabilities include verifiable credentials, selective disclosure (including zero-knowledge proofs and pairwise identifiers), smart contracts that govern roles and interactions, APIs, and integrated/reusable KYC support. Adoption also depends on emerging interoperability standards (W3C DIDs/Verifiable Credentials, DIF, RWOT DID Auth, Open Badges) and an honest assessment of maturity, integration complexity, scalability tradeoffs, and evolving security threats.

• Decentralized identity emerged in response to blockchain technologies and increasing demand for user control over PII.
• Enterprises that manage customer accounts must store and manage user data, creating large, high-value attack targets.
• Password reuse is a common user behavior that creates security weaknesses in digital identity management.
• The increase of uniquely identified IoT devices exacerbates the problem of siloed identity data.
• Decentralized identity solutions typically address identity proofing and the secure storing and sharing of identity credentials.
• Verifiable credentials are intended to be cryptographically secured and tamper-proof, aligning with emerging W3C standards.
• Zero-knowledge proofs can prove an identity characteristic without disclosing the underlying information.
• Pairwise identifiers are relationship-specific identifiers unique to a particular user–third-party relationship.
• Emerging decentralized identity standards include W3C DIDs/Verifiable Credentials, DIF Universal Resolver/Identity Hubs, RWOT DID Auth, and Open Badges.
• Storing PII on-chain is described as an immediate red flag; only a hash of encrypted PII should be stored on-chain.

• “Decentralized identity is a sub-category of traditional Identity and Access Management (IAM) solutions that has emerged in response to the development of blockchain technologies and to public demand for more control over personally identifiable information (PII) data.”
• “This yields two difficulties: first, enterprises are saddled with a honeypot of data – a vulnerability that must be protected – and users seek out ways to simplify their many accounts by reusing passwords.”
• “Decentralized identity solutions serve to create a different infrastructure for managing digital identity that returns control of PII data to the individual owner.”
• “As a niche technology, decentralized identity solutions are developed with the assumption that their users will also rely on traditional Access Management and Lifecycle Management processes, such as federation.”
• “It is necessary to have a clear understanding of your own enterprise’s identity needs before identifying possible solutions.”
• “The ability to choose which identity information to share is a powerful selling point for decentralized identity solutions.”
• “Smart contracts are software that self-deploys when certain conditions are met, and are often used in conjunction with blockchain infrastructures.”
• “The challenge remains that these are emerging standards, with the technologies, their capabilities, and thus their interoperability needs continually developing.”
• “Decentralized identity is visionary, and attempts to address the lack of an identity layer built inherently into digital interactions.”
• “Whether or not you choose to adopt a blockchain solution, these concerns do exist and should be addressed in the way you manage enterprise IAM.”
