Blockchain-based_Service_Network
The Blockchain-based Service Network (BSN) is a backend architecture in China for developing and managing blockchain-based applications,[1] split into Chinese and International uses.[2] BSN China was established in 2018 and launched in 2020 by the State Information Center under the National Development and Reform Commission of China, China Mobile, China UnionPay(state-owned payment and settlement provider), and a technology architect.[1][3] BSN International operates under the Singapore-based BSN Foundation.[2]

The BSN integrates both private and public blockchain frameworks and cloud service providers to build the underlying development and production environment,[4][5] where enterprises, governmental bodies, and financial institutions can build Blockchain-as-a-Service Systems and blockchain applications while being compliant with China's regulations of non-cryptocurrencies.[6][7] China's state-level decentralized identifier system, China RealDID, is deployed on BSN China.[8]
As a digital infrastructure along the Belt and Road Initiative, the BSN works on interoperability across blockchain systems[9] and develops a public IT system/multi-party system concept that uses blockchain as an operating system, including permissioned and permissionless blockchain infrastructures.[10]
On November 8, 2023, BSN was listed in a US House of Representatives proposed bill aimed at preventing US federal agencies from utilizing China-developed blockchain networks or engaging with related companies due to national security concerns.[11]
