An alliance of Chinese government groups, banks, and technology companies will publicly launch the Blockchain-based Service Network (BSN) next month. It will be among the first blockchain networks to be built and maintained by a central government. Think of it like an operating system, where participants can use existing blockchain programs, or build their own bespoke tools, without having to design a framework from the ground up.
The BSN’s proponents say it will reduce the costs of doing blockchain-based business by 80 percent. By the end of 2020, they hope to have nodes in 200 Chinese cities. Eventually, they believe it could become a global standard.
“And, though China has effectively banned cryptocurrencies like Bitcoin, digital payments are wildly popular. Most people prefer to use WeChat or Alipay,” says Hong Wan, a blockchain expert from North Carolina State University.
The biggest roadblock for blockchain technology has been that setting up a platform is expensive and difficult, says Yang Xiang, the dean of the Digital Research Innovation Capability Platform at Swinburne University in Australia.
“When we look back at the development of blockchain technology, the emergence of BSN or similar solutions is inevitable,” he says.
According to a white paper published by the BSN’s founding members—which include the Chinese National Information Center, China UnionPay, China Mobile, and payroll services company Red Date—most companies can expect to spend at least US $14,000 to build, operate, and maintain a blockchain platform for one year.
The BSN will let programmers develop blockchain applications without requiring them to do so much heavy lifting. The white paper estimates it will cost businesses, on average, less than $300 to deploy an application on BSN.
Unlike Bitcoin and other so-called permissionless blockchains, where anybody can join and review the entire transaction record, applications running on the BSN will have closed membership by default. This ‘permissioned’ setup is much more amenable to businesses, which typically want to share transaction data only with trusted partners. Permissioned networks are also easier to scale, because all verifications happen in-house.
The BSN’s founders announced the platform on 15 October 2019—about a week before Chinese President Xi Jinping declared blockchain a national tech priority. Since then, individual developers and enterprise-scale engineering groups have been building and beta testing the platform. By launch time, the BSN Development Alliance says it hopes to have 100 city nodes running the platform, each with thousands of users.
The BSN Alliance hopes the platform will someday become the global standard for blockchain operations. But, China’s international partners may hesitate to join due to privacy concerns: The Chinese government will hold the BSN’s root key, which would allow it to monitor all transactions made using the platform.
