The Blockchain Services Network (BSN) is emerging as a foundational layer in the global push toward decentralized digital infrastructure. Designed to streamline access to blockchain technology, BSN offers a suite of interoperable services that enhance identity management, domain resolution, asset tokenization, and system transparency. These tools are engineered not only for enterprise adoption but also to empower individuals with greater control over their digital identities and assets.
This article explores the core components of BSN, including its DID services, distributed domain systems, DDC solutions, and monitoring platforms—each playing a pivotal role in shaping a secure, unified, and user-centric Web3 ecosystem.
🔐 BSN Real-Name DID Service: Verified Identity on the Blockchain
At the heart of digital trust lies identity verification. The BSN Real-Name DID Service leverages official government infrastructure to issue verifiable digital identities. Operated in collaboration with Zhongdun Anxin (Xiamen), a subsidiary of the First Research Institute of the Ministry of Public Security, this service uses China’s CTID (Cyber Trusted Identity) system to authenticate users via real-name credentials—either "ID number + name" or enhanced with facial recognition.
Once verified, each individual receives a unique, persistent Decentralized Identifier (DID). Notably, even if the same person registers through multiple service providers, their DID remains consistent across platforms. What changes is the public key stored within the DID document—allowing different applications to use distinct cryptographic keys while maintaining identity continuity.
These public keys are published on the BSN Yan'an Chain, making them publicly accessible for encryption and signature verification. Meanwhile, private keys remain securely held by either the user or an authorized business entity. This model ensures both security and interoperability: any organization can verify transactions or encrypt data using the authenticated public key from the official DID record.

🌐 All Link DNS Service: A Unified Domain Layer for Web3
Navigating decentralized networks often means dealing with complex, chain-specific addresses. The All Link DNS Service solves this by introducing a universal domain naming system built on the BSN Yan'an Chain—a blockchain jointly governed by the National Information Center, China Academy of Information and Communications Technology (CAICT), and Zhongdun Anxin.
This distributed domain service creates a single, globally recognized namespace that works across all blockchain environments: public chains, consortium chains, and private chains alike. Users can register a domain once and use it to point to various endpoints—such as wallet addresses, smart contracts, DIDs, or accounts—on any supported chain.
Crucially, ownership control stays with the user. Through cryptographic proofs recorded on-chain, domain owners retain full authority to update mappings across networks without relying on centralized registrars. This paves the way for seamless cross-chain interactions and simplifies user experience in an increasingly fragmented blockchain landscape.
📊 Trusted Blockchain Operation Monitoring Platform
As enterprises adopt private and consortium blockchains for critical operations, ensuring system integrity becomes essential. The Trusted Blockchain Operation Monitoring Platform, co-developed by CAICT and China Mobile Design Institute, acts as a regulatory-grade oversight mechanism—akin to traditional ICP (Internet Content Provider)备案—but tailored for blockchain systems.
This platform enables real-time registration and monitoring of active blockchain networks. It records operational status, verifies data consistency, and detects unauthorized modifications such as chain reorganizations or data tampering. Organizations deploying compliant blockchains can register their nodes and have their network status independently validated.
Transparency is built-in: anyone can query the platform via its official website or through APIs available on the DDC Network to confirm whether a given blockchain is operating legitimately. This functionality strengthens auditability, supports compliance efforts, and builds confidence among stakeholders interacting with enterprise-grade distributed ledgers.
🎨 BSN Official DDC Service: Secure Digital Asset Creation
Digital assets are central to the evolution of digital economies. BSN’s Official DDC (Distributed Digital Certificate) Service provides a trusted framework for issuing non-fungible tokens (NFTs) and other digital collectibles under widely accepted standards—ERC-721 and ERC-1155.
Managed by the BSN Development Alliance, these official contracts are audited and maintained to ensure long-term reliability. Assets created through this service benefit from BSN’s endorsement, guaranteeing their security, immutability, and persistence. This backing is especially valuable for institutions seeking durable digital asset management solutions without exposure to rogue smart contracts.
Moreover, DDCs issued via BSN can move freely across participating platforms and open consortium chains within the DDC Network. For international use cases, BSN supports one-way cross-chain transfers to overseas public blockchains—enabling global reach while maintaining regulatory alignment.

🔑 BSN Private Key Custody Service: Secure Recovery Without Centralization
One of the biggest barriers to mainstream blockchain adoption is private key management. Lose your key, lose your assets—with no recovery option. To address this, BSN is developing a Private Key Custody Service anchored in its real-name DID infrastructure.
This upcoming service links custody arrangements directly to verified DIDs and distributed domain names on the Yan'an Chain. When a user authorizes a business system to store their private key, that association is cryptographically secured and tied to their verified identity.
If access is lost, users can recover or regenerate their private key using government-issued ID verification, eliminating reliance on seed phrases alone. This approach balances security with usability—mitigating risks associated with self-custody failures or centralized custodial vulnerabilities.
By integrating identity verification into key recovery, BSN introduces a novel model where convenience does not come at the expense of decentralization.
🆔 BSN-DID Service: Open Source Identity Infrastructure
Beyond real-name verification, BSN offers a broader BSN-DID Service designed for general-purpose digital identity needs. As an open-source and freely accessible infrastructure, it supports integration into any IT system requiring secure authentication.
BSN-DID enables:
- User-controlled identity management
- Cross-platform transaction signing
- Secure personal data handling
- Verifiable credentials for access control
It addresses common pain points in traditional authentication models—such as weak password security, cumbersome multi-platform logins, and lack of user data sovereignty. With BSN-DID, developers can build applications where users truly own and manage their digital footprint.
This service aligns with global trends toward self-sovereign identity (SSI), offering enterprises a compliant, scalable path into decentralized identity ecosystems.
Frequently Asked Questions (FAQ)
Q: What makes BSN’s DID service different from other digital identity solutions?
A: BSN integrates government-verified identity through China’s CTID system, ensuring high-assurance authentication while preserving decentralization via blockchain-based DID documents.
Q: Can I use my BSN-issued DDC on Ethereum or other international blockchains?
A: Yes—BSN supports one-way cross-chain migration from its DDC Network to overseas public chains like Ethereum, allowing compliant international usage.
Q: Is the All Link DNS Service compatible with existing domain names?
A: While it operates as a separate naming system, it functions similarly to traditional DNS but is optimized for blockchain addresses and cross-chain interoperability.
Q: Who can access the Trusted Blockchain Monitoring Platform?
A: The platform is publicly accessible—any individual or organization can verify registered blockchain networks via web interface or API.
Q: Will private key recovery compromise my security?
A: No—the recovery process uses multi-layered encryption and strict identity validation to prevent unauthorized access while enabling legitimate recovery.
