The Blockchain-based Service Network (BSN) is a non-cryptocurrency blockchain infrastructure that enables a distributed cloud environment within existing private or public clouds for mainstream businesses or institutions to build and manage distributed applications.[1] The BSN was founded in 2018 under the lead of the State Information Center of China, a government think tank under the National Development and Reform Commission, and was officially launched in 2019. Other founding members include China Mobile, China UnionPay, and Red Date Technology Limited.[2] The BSN’s primary function is to provide a set of DLT-based cloud environment software[3], supporting traditional cloud service providers, data centers, and businesses in setting up private or public[4] distributed networks and thus simplifying the adoption of blockchain technology for their users.[5][2]
On April 25, 2020[6], The Blockchain-based Service Network (BSN) was announced for commercial use, categorized into Chinese and International operations.[7] On June 29, 2022, the BSN-DDC Network surpassed Ethereum’s transaction volume (938,166 transactions) within a 24-hour period (974,517 transactions).[8] In September 2022, the BSN Spartan Network, the equivalent of BSN-DDC outside Mainland China, was officially launched in Hong Kong with initial adopters including HSBC, Prenetics, and FUJIFILM Business Innovation Hong Kong.[9]
The Blockchain-based Service Network functions as an infrastructure network rather than a standalone blockchain protocol, integrating dozens of independent blockchain frameworks.[10][11] The BSN establishes a foundational cloud environment supporting the deployment of distributed Multi-Party Systems, or Public IT Systems[12], which allows developers on these platforms to use shared computing resources rather than installing a full set of cloud services or computing infrastructure. [13][14]
The technology stack of the Blockchain-based Service Network includes both Enterprise BSN and Public BSN. The latter operates under two distinct governance frameworks for Mainland China and international users.
The technology stack of the Blockchain-based Service Network (BSN)
Enterprise BSN
Enterprise BSN is an enterprise-level software platform integrated into public cloud, private cloud, or intranet for enterprises and institutions to embed a blockchain-based environment into their existing systems.[15] While traditional cloud environments handle centralized private IT systems, Enterprise BSN, working in parallel, manages distributed Multi-Party Systems or Public IT Systems to establish a private network where developers can design, deploy, and manage the lifecycle of blockchain applications.[16]
Enterprise BSN's environment can manage cross-cloud, cross-framework, and cross-application virtual machines and resources directly on top of OpenStack.[17] The platform integrates permissioned frameworks like Hyperledger Fabric and FISCO BCOS and public blockchains such as Ethereum and EOS as operating systems.[18]
Public BSN
BSN-DDC Network
The BSN-DDC comprises over ten Open Permissioned Blockchains (OPBs), adapted from public chain blueprints such as Ethereum to align with Chinese regulatory frameworks.[19] The network operates exclusively in Mainland China and adopts Distributed Digital Certificate technology, a “Chinese version of NFT,” as the certification and distributed database technology that can be applied in business or government scenarios where digital proof is required.[20] The data center software of the BSN-DDC Network mandates permissions and KYC procedures.[21] Examples include Xi'an Qujiang Cultural Tourism and Chongqing News's Shangyou News, both of which have established DDC platforms on the BSN-DDC Network to promote local culture and tourism industries.[22]
BSN-Spartan Network
The BSN Spartan Network is a public infrastructure network built on the BSN Spartan data centers, which functions as the gateway to the network and is open-source, free, and KYC-free[23][24], operating exclusively outside Mainland China[25]. The BSN Spartan Network integrates several Non-Cryptocurrency Public Chains (NC Chains), which are non-crypto hard forks derived from their original public chains.[2] The network is developed to support the adoption of blockchain for mainstream enterprises without exposure to the volatility and regulatory uncertainty of the cryptocurrency market.[26]
Bifurcated Operation
According to the United States–China Economic and Security Review Commission’s investigation, the BSN architecture is bifurcated between Chinese and international users.[1] BSN China operates under the guidance of the BSN Development Association (BSNDA), which is backed by Chinese government-linked entities and major state-owned enterprises [27]and uses cloud infrastructure from China Mobile, China Telecom, and Baidu AI Cloud[28]. The BSN Spartan Network functions independently under the BSN Foundation based in Singapore, and uses Amazon Web Services[18] and other commercial cloud service providers in Hong Kong, USA, and Europe[28]. In November 2023, five founding members of the BSN Foundation were announced in Singapore: Blockdaemon, GFT Technologies, TOKO, Zeeve, and Red Date Technology, with membership from the USA, Europe, and Asia.[29]
Despite the separation of the Chinese vs international businesses, BSN's Chinese origins have elicited apprehension from some in the global community.[30] These concerns are reminiscent of challenges faced by companies such as TikTok vs DouYin.[31] On Nov 8, 2023, a U.S. bill[32], titled the Creating Legal Accountability for Rogue Innovators and Technology (CLARITY) Act, proposed to outlaw federal agencies from using the Blockchain-based Service Network (BSN) and its IT infrastructure service Spartan Network, along with the tech provider Red Date Technology over national security and privacy concerns.[33]
BSN Foundation member Red Date Technology responded to media requests for comment in a statement clarifying that BSN is a politically neutral, application-agnostic technology initiative. The Spartan Network is fully open source for code auditing and is under decentralized governance by the Singapore-based BSN Foundation. The Hong Kong-based Red Date Technology, a voting member of the Foundation, holds no special status.[26]
