Original title: China's Blockchain Infrastructure to Extend Global Reach With Six Public Chains

Key points:

• BSN, a blockchain service network supported at the Chinese state level, has cooperated with 6 public chains including Tezos, NEO, Nervos, EOS, IRISnet and Ethereum.

• Beginning on August 10th, developers on these six public chains will be able to use data storage and bandwidth from BSN overseas data centers to build DApps and run nodes.

• Global users will access China's enterprise chain and financial data through the cross-chain structure of the network and the partnership with China UnionPay.

The Chinese name of BSN is Blockchain-based Service Network (Blockchain-based Service Network, hereinafter referred to as Service Network or BSN), which is a cross-cloud service, cross-portal, and cross-bottom framework for deploying and running a global public foundation for blockchain applications The facility network is jointly initiated by China State Information Center (SIC), China Mobile Communications Corporation, China UnionPay Co., Ltd., and Beijing Jujube Technology Co., Ltd. The Internet is formed by connecting cloud resources and data centers of all parties through the TCP/IP protocol, and BSN is formed by connecting cloud resources and data centers belonging to all parties through a set of blockchain protocols. Belonging to any single organization is public infrastructure.

The Chinese government-backed blockchain infrastructure will open its services globally on Aug. 10 for developers of decentralized applications (DApps) around the world.

The move is part of China's plan to become an infrastructure provider for blockchain companies, similar to China's strategic deployment in other major emerging technologies such as 5G and artificial intelligence.

At present, China's global blockchain strategy is still going smoothly.

The global version of BSN has integrated its data center with six public chains, namely Tezos, NEO, Nervos, Cosmos’ IRISnet, Ethereum and EOS. Developers on these public chains can use the data storage, bandwidth and other resources provided by BSN to run nodes and applications.

The cheap services provided by BSN, the interoperability with other Chinese enterprise blockchains, and the advantage of obtaining financial data from China UnionPay will benefit these public chains, because it is difficult for foreign blockchain companies to obtain and process such data.

He Yifan, CEO of Beijing Jujube Technology Co., Ltd., one of the founding companies of BSN, said, “This is a milestone, because BSN is the first state-backed blockchain infrastructure to enter the world by integrating with major public chains. developer community."

Launched in April, the project is led by the State Information Center of China (SIC) and supported by China Mobile and China UnionPay, as well as Jujube Technology, which designed the technical framework of the BSN.

SIC is a public agency under the National Development and Reform Commission (NDRC), the top economic planning agency of the Chinese government. The agency has been one of the main architects of China's national information security policy and monitors and processes macroeconomic data for policymakers.

He Yifan said that these six blockchain projects are BSN's first batch of decentralized public blockchains, which can run on its network of three data centers across Paris, San Francisco and Hong Kong.

He said: "We have thought a lot about which public chain can be the first to be integrated." He Yifan also mentioned, "In addition to the Ethereum and EOS we disclosed in April, we also decided to join another A public chain Tezos, and two well-known projects NEO and Nervos launched in China.”

Blockchain Cloud Service

Lu Guoning, co-founder of Nervos, said that BSN can provide blockchain developers with tailor-made infrastructure services, noting that projects need to run nodes on this architecture to run.

"Essentially, blockchain companies are using BSN's standardized internet services, rather than adapting their own technical frameworks to use such services," Lu said.

The standardized development environment saves developers a lot of time and money, Lu said.

In this regard, Cao Haili, the founder of the IRISnet Foundation, believes, “For example, verification nodes require high-level security protection to prevent nodes from being subjected to Distributed Denial of Service (DDoS) attacks (one of the most common network attacks, making users unable to use the network) )."

The BSN will hide these complex security functions in the course of its operations. Cao said that in the future, developers can use BSN to run nodes just like cloud services, and developers can search for the name of the blockchain and hold its private key to build a DApp or run a node.

If developers make less than 2,000 requests to BSN nodes per day, they will enjoy free services on BSN. Jujube’s He Yifan claims that for DApp developers, BSN will be more cost-effective and stable than other networks.

Blockchain projects have free nodes, but once a DApp loses connection to a node, they become unstable and difficult to track. Many DApps purchase services from Amazon Web Services (AWS) and build their own nodes in data centers.

The disadvantage of this is that the cost is too high. For example, for a single node on a network like Alibaba Cloud, developers must pay tens of thousands of dollars in human resource costs every year to maintain the node.

APIs

Although BSN only contains six public chains, users will have more than a dozen options to choose from after linking with BSN nodes.

All six public chains will be allocated to mainnet and testnet nodes, through which developers can first run their applications on the testnet and discover potential problems to ensure smooth and unimpeded real operation.

While all chains can connect to nodes through their native application programming interfaces (APIs), Ethereum and EOS developers can opt for API services provided by third-party blockchain middleware company dfuse.

For Ethereum and EOS, there will be Mainnet nodes, testnet nodes, and dfuse nodes, with their own special API structures attached to the nodes.

Founded in 2018, dfuse is a Montreal, Canada-based company that initially provided API services for EOS-based applications and later expanded to projects on Ethereum.

Alexandre Bourget, co-founder and chief technology officer of dfuse, said: "BSN has taken a fancy to our scalability. dfuse has been built on a public chain that can handle 5,000 to 10,000 burst transactions per second and It has passed the stress test and is ready to deal with the next 10 times and 100 times the current volume of the industry."

One network, two systems

Developers can build DApps on the six public chains of the BSN global version, but domestic policies tend to restrict public chains that have issued tokens.

Da Hongfei, founder of NEO, said: "The Chinese government and regulators are very cautious about distributed public chains, and try not to get involved in anything related to public chains. But BSN has a clear commercial purpose and is supported by entities with government background. Enterprise support, including public chain systems, so this is very interesting.”

Da Hongfei said that like ByteDance behind TikTok, the international version of the app does not necessarily comply with Chinese regulations, but the local regulations of the country where it is located, and BSN embodies a common pragmatic approach for Chinese companies to go global.

BSN can serve as a channel for non-Chinese blockchain companies to enter the Chinese blockchain community.

Developers outside of China can use many Chinese enterprise blockchains to build their DApps, Da Hongfei said.

Hubertus Thonhauser, Chairman of the Council of the Tezos Foundation, said: "We are delighted that Tezos has joined the queue of public blockchains, which will enable companies and software developers to build blockchain-based blockchains in China and around the world. applications providing the base layer. Participation in the BSN is an important step for the Tezos project on the path to widespread institutional adoption.”
