China moves blockchain and AI filings to one national portal

The platform, at beian.cac.gov.cn, replaces the former Internet Information Service Algorithm Filing System and Blockchain Information Service Filing Management System, the CAC said. The domain had already served as the official address for algorithm filings since a February 2022 notice; that system opened in March 2022. The new announcement describes a shared administrative portal, but does not set out changes to the requirements for individual services.

China’s Blockchain Information Service Management Provisions, effective since February 2019, apply to public information services delivered through websites or applications using blockchain technology. Providers must file within 10 working days of starting a service, giving details including the service name and category, delivery format, application field and server address. Changes to a service or website address must be reported within five working days. Providers must begin cancellation procedures 30 working days before ending a service. Authorities have 20 working days to register complete filings or explain why incomplete submissions cannot be registered.

The rules also require registered providers to display their filing numbers and periodically check their information. A CAC explanation issued in January 2019 describes related obligations: authenticating users’ real identities, managing content security, publishing platform rules and agreements, and responding to unlawful activity or content. New products, applications and functions require safety assessments under applicable rules. Providers must keep backups for at least six months and supply them when law enforcement authorities lawfully request them.

Crypto-related business restrictions are set out separately. A February 2026 notice from the People’s Bank of China and seven other authorities prohibits virtual currency exchange, token financing and other specified financial activities. It also bars business registration names and scopes from using terms such as “virtual currency,” “crypto assets,” “stablecoin” and “RWA.” The Nov. 9 portal announcement does not introduce those restrictions. The separate notice also bars overseas organizations and individuals from illegally providing virtual currency services to mainland entities, and prohibits domestic real-world asset tokenization except for authorized activity through designated financial infrastructure.
