China is developing a digital identity infrastructure that combines government-backed identity checks with blockchain-based credentials. The goal is to make identity verification more portable across platforms and support trusted data exchange. However, blockchain digital identity in China does not mean that citizens can operate entirely anonymous identities outside government oversight. The emerging model connects user-controlled credentials with authorised institutions and state-recognised verification.
What is decentralized digital identity?
Decentralized identity, called DID, is a way to represent a person, organisation or device through a unique digital identifier. Instead of every website creating a separate identity record, a user can hold credentials issued by trusted organisations and present them when needed.
A DID typically uses cryptographic keys, a digital identifier and verifiable credentials. The identifier points to a record containing public information needed to verify control. A credential may confirm a specific fact, such as a qualification, professional licence or age. A verifier checks its digital signature and validity.
How does China’s blockchain identity system work?
China’s approach combines authoritative identity verification with distributed technology. In June 2026, the Cyberspace Administration of China published a draft regulation seeking public feedback on the interoperability and mutual recognition of distributed digital identities. The proposal describes an identity built from an identifier, cryptographic keys, verifiable credentials and verifiable claims.
Under the draft, individuals and organisations could voluntarily register through an identity chain after verification by an authorised identity institution. The system would issue a DID and a real-name identity credential. Government agencies, companies, schools and other approved organisations could issue credentials confirming particular attributes. Users could then present selected credentials to service providers, which could verify authenticity through the identity infrastructure.
The proposal is a draft, not proof that every feature is already operating nationwide. It sets out a framework for common standards, trusted issuers, application providers and cross-platform recognition.
What role does China’s national blockchain network play?
China’s national blockchain network is intended to provide shared infrastructure for applications that need trusted records and coordination across organisations. The Blockchain-based Service Network, or BSN, was initiated by the National Information Center with partners including China Mobile and China UnionPay.
BSN offers infrastructure for distributed applications and has developed identity-related services. Its real-name DID service, launched in December 2023, links identity verification to a distributed identifier. The BSN model is described as allowing business-side pseudonymity while retaining real-name verification for authorised oversight.
A blockchain identity does not automatically mean that personal information is written openly to a public ledger. Systems can place verification data and cryptographic proofs on-chain while keeping sensitive information in controlled systems.
How does blockchain ID verification work?
A typical process has four stages. First, an authorised institution verifies a person’s identity using accepted documents or official records. Second, a DID and cryptographic keys are created. Third, an issuer provides a digitally signed credential, such as proof of education or an organisation’s legal status. Finally, a service provider checks the credential’s signature, issuer and validity.
Where supported, selective disclosure allows a user to reveal only the required attribute rather than an entire identity document. For example, an age check may confirm that someone is over a required threshold without displaying their date of birth. This can reduce unnecessary data collection, although the level of privacy depends on system design and implementation.
Digital identity privacy in China: what should users know?
The proposed framework says users may voluntarily apply for, hold, use and deactivate distributed identities. It also describes selective disclosure of credentials and claims. At the same time, identity issuance depends on authoritative verification, and the proposal provides for authorised institutions and oversight.
Privacy therefore depends on who holds the underlying data, what information is recorded on the blockchain, how keys are secured, and when identity tracing is legally permitted. Blockchain records can be difficult to alter, so systems should avoid placing sensitive personal details directly on-chain. Users should also understand whether an application provider stores copies of credentials or links activity across services.
What happens next?
China’s digital identity framework is still developing. The June 2026 consultation draft signals an effort to establish common rules and connect identity services across sectors such as finance, transport, customs and taxation. A separate national online identity authentication service, effective from July 2025, provides voluntary network identity credentials known as “Internet IDs” and certificates. It should not be confused with every blockchain-based DID initiative.
The challenge is ensuring interoperability, security, accountability and meaningful user choice.
For businesses, blockchain identity verification could streamline onboarding and credential checks. For individuals, the value will depend on whether credentials are portable and privacy protections are clear. China’s model is not simply decentralisation replacing government identity systems. It is an attempt to combine trusted official verification with reusable digital credentials and distributed infrastructure.
