Why did BSN choose six public chains, including Ethereum, EOS and Nervos, as the first integration project?

Recently, the term "National team" has been appearing on the front page of the media at home and abroad. The announcement of BSN's integration with the six major public chains has hit the social media circle for a while, and overseas media have reported it as the top news for two consecutive days.

Since last year, the pace of distribution in the blockchain field has suddenly accelerated. China has decided to take blockchain technology as a breakthrough point for independent innovation of core technologies. Then it announced the launch of central bank digital currency DCEP. In the same year, Facebook announced "Libra", a basket of stability COINS.

In this context, the subtle progress around BSN presents a curious phenomenon of greater concern abroad than at home. Why did BSN choose six public chains, including Ethereum, EOS and Nervos, as the first integration projects? What is the impact of the "BSN effect" on the competition between different countries in the blockchain field?

According to BSN's official website, the Blockchain-based Service Network (" BSN ") is a global public infrastructure Network with cross-cloud Service, cross-portal and cross-underlying framework for the deployment and operation of Blockchain applications.It was jointly launched by the State Information Center, China Mobile Communications Corporation, China UnionPay And Beijing Jujube Technology Co.

In a nutshell, BSN is responsible for creating the foundation of a building, which allows the user to develop, and the tools and foundations needed for development are provided by BSN, which helps the developer to develop more easily. It can be seen that WHAT BSN needs to do is to integrate the network and reduce the development, deployment, operation and maintenance costs of the public infrastructure network. Bsn-based developers do not need to buy a cloud service to build their own blockchain operating environment. Instead, they use the same public service and share resources together.

BSN will be officially released on October 15, 2019, with private testing completed six months later.

The launch of BSN is in line with the new infrastructure work that has been advocated by the country. According to the government work report for 2020, the new infrastructure includes information infrastructure, fusion infrastructure and innovation infrastructure. Among them, the information infrastructure contains the new technology infrastructure represented by block chain.

The emergence of BSN is a great support for small and medium-sized teams and even individuals to touch the blockchain technology and develop the infrastructure of Dapp. Although the traditional BaaS platform has largely simplified the workload of developers, its operation and maintenance costs are still high, and it is still difficult for individuals and small enterprises to use. BSN, on the other hand, solves the cost problem and is a more scalable version of BaaS.

Note: Bass, "back-end services", for Web applications and mobile application developers to provide the application links to the backend application and open the back-end cloud storage and API method, including the cloud data/file storage, account management, data collection, operation analysis, news feeds, social media integration, etc.

It is understood that BSN's operating cost is only 20% of that of traditional blockchain cloud services. With BSN, an app can be chained and started running at only 2000-3000 RMB per year, which will greatly reduce the operation and maintenance costs of blockchain developers.

BSN integrates ethereum, Nervos, EOS and other six major public chains

If BSN were merely acting as an "internal network," it might not attract attention overseas. However, in April this year, BSN revealed that it will integrate ethereum and EOS, both domestic and overseas public chain projects. In particular, on the evening of July 21, THE blockchain service network BSN announced the integration of six major public chains, including Nervos, Tezos, NEO, EOS, IRISnet and Ethereum. The decision ignited foreign media attention and began the ongoing coverage of BSN.

Starting from August 10, developers of the six blockchain platforms will be able to build AND run dApp nodes through the data storage and bandwidth of BSN's overseas data centers. The six blockchain projects are the first batch of decentralized public chains integrated by BSN, which will provide operational support on its network of three data centers located in Paris, San Francisco and Hong Kong.

After BSN announced the partners, many people began to wonder why the six major chains attracted BSN's attention and why BSN chose the partners.

The diversity of BSN in public chain cooperation

State-controlled bharat sanchar nigam Beijing red technology co., LTD., one of the sponsors what queer CEO said: "about who can be the first to be integrated and chains, we consider a lot. Besides we disclosed in April Ethereum and EOS, we decided to another international chain Tezos, and two originated in China's famous chain Nervos and even include NEO." In fact, each of the first public chain projects was unique and representative.

For example, Ethereum and EOS are currently the two most popular public chains among Dapp developers, and the number and actual usage of DAPPS created based on these two public chains are among the top of the public chain. And IRISnet had been chosen by BSN along with Chainlink as a cross-chain technology project. As an old domestic public chain, NEO also enjoys certain popularity overseas. Nervos, with its unique layered approach and support for multilingual development, is one of BSN's first collaborative chains.

Ethereum is currently a pilgrimage site for blockchain developers.

Say the lack of the etheric fang public service chain is incomplete, even now have so-called "the etheric fang killer" of the big project finally launched its own test network, provids, etheric lane under the condition of Gas costs so high, there is still no a male chain can boldly say has transcended the etheric lane position in the block chain industry. Ethereum's first-mover advantage has created a huge user base and laid a solid foundation for development. Ethereum may not be mature enough, but it has spawned a number of DAPPS and is the first choice for many decentralized application developers to deploy their products and services. Currently, the big DeFi projects (such as Uniswap, Compound, Curve, etc.) are built on Ethereum.

According to the second quarter of 2020 issued by the DappReview Dapp market report, the etheric fang DeFi project strong: DeFi total transactions grew by 403% from a year earlier; Several excellent Ethereum DeFi projects more than doubled in value in the second quarter. Meanwhile, Ethereum's total TRANSACTION volume of Dapp in Q2 of 2020 was 14.27 billion US dollars, up 334% from the same period last year (3.28 billion US dollars).

Ethereum is an excellent choice for the BSN network to encourage innovation: a relatively safe, viable business model and an active community (i.e., a sufficient user base, a mature technology that is widely available, and a wide range of products that are already complete and in use). With this integration with BSN, developers on the Ethereum chain will also be able to build DApp and run nodes on BSN.

It can be seen that among BSN's six partners, there are two domestic public chain projects (Nervos and NEO) and the other four overseas public chain projects (Ethereum, EOS, IRISnet and Tezos). According to the public information, BSN expects to increase the number of public chain integration to more than 10 by the end of 2020 based on user base, technical background and product conditions.

The reasons for choosing an established public network like Ethereum are obvious, but why would BSN take a look at Nervos, which has been online for less than a year?

Old public chain ideas like Ethereum fell into place and built the development framework from zero. The task of the new generation of common chains, such as Nervos, is to optimize and solve the problems found in the use of the old generation of common chains, such as scalability, security and so on.

The Nervos solution is that it takes a Layer1 + Layer2 approach as a whole. In the whole network, Layer1 CKB is the value store layer of the whole network. Based on the bitcoin consensus, it breaks through the performance limitation and increases the ability to resist selfish mining. Layer2 provides higher scalability and lower transaction costs on top of that and is responsible for network computing. This approach can effectively extend the performance of blockchain, and the design idea also conforms to the consortium chain combined with the public chain architecture proposed by BSN.

Among the six public chains in this cooperation, we can see that most of the projects adopt PoS or DPoS mechanism, and Ethereum is also in the process of moving from PoW to PoS consensus. However, Layer 1 of Nervos still adopts the PoW consensus mechanism, so as to ensure that the entire network can enjoy the most secure underlying platform, and it also becomes the only project in the first batch of cooperative public chain that still adheres to the underlying PoW consensus mechanism.

In their insistence on consensus, Nervos believes that the blockchain network that takes on the role of Layer 1 must be license-free to ensure that Layer 1 is a globally Shared, neutral facility. The PoW mechanism is exactly in line with the above concept. As long as there is mining equipment, anyone can directly invest in mining machine and electricity to participate in the protection of network security. The Eaglesong algorithm adopted by the Eaglesong algorithm is neutral to Asic, so more nodes can be involved in mining to avoid over-concentration of computing power and thus centralization. The Nervos computing power has increased from about 73.47th /s at the beginning to 11.53pH /s (1PH=1000TH), with an increase of nearly 157 times.

However, for BSN, in addition to meeting the technical requirements of the public chain, the development idea of Nervos also coincides with BSN's vision of building a global infrastructure network.

In this year's consensus conference, Nervos chief architect, said "the intelligent platform to become mainstream, contract should embrace the" traditional "developers. A new contract at intelligent platform to become mainstream, need to" traditional "developers can use any programming language they are familiar with, rather than creating a new language and forced them to use". As a global infrastructure, BSN will attract many outstanding developers from around the world.

Nervos's CKB virtual machine (CKB-VM) enables "one compile, one run, one run" (on the blockchain, a virtual machine is a smart contract environment, a complete computer system that can be completely isolated from the outside world). Simply put, in traditional Internet development environments, the popular Java-built virtual machine enables programs to be built on multiple systems with just one code write. The Java virtual machine is not suitable for a blockchain development environment that requires consistent results for all calculations.

For BSN, which wants to encourage developers to join, Nervos supports programming and writing smart contracts in multiple languages in a number of ways that coincide with BSN's promotion ideas. If the public chain is more friendly to traditional developers in terms of developing languages, it will undoubtedly greatly lower the barrier to entry for development and meet the needs of more developers.

In terms of product placement, Nervos Network announced a $30 million public fund this year to fund outside developers to build on its blockchain infrastructure. It also launched a virtual incubator called "CK Labs" to fund start-ups to develop data applications on the Nervos platform to enrich the ecosystem.

Nervos has been online for more than half a year, and the underlying framework is getting better and better, laying a solid foundation for developers to flood in and create Dapp in the future.Among the six public chains integrated by BSN, Nervos is also the only "new" project whose main network has been online for less than one year. It can be said that its development speed and stable underlying construction have played a significant role.

New opportunities for domestic public chains

Since its launch in April this year, BSN has been on a clear and highly efficient path of development. From the very beginning, it was confirmed that it would integrate Ethereum and then build a cross-chain service center with Chainlink, IRISnet and Jujube technology to realize the first step of interoperability between DAPPS in the network.

As China seeks an opening to push its own technologies or standards overseas, 5G and other technologies have been hampered in the international arena. The block chain is a preferred breakthrough for external development due to its special properties of open source of industry technology and community consensus and openness. Overseas have also observed the start and development of BSN in China. On the one hand, they pay close attention to it, either because it is a rare national power to get involved in the blockchain industry, or because they sense a sense of crisis in the rapid development of BSN.

Although there are only two domestic public chains in this integrated project, NEO, as a well-established public chain, has always kept its place in this rapidly changing market, but some innovations and progress are missing. Nervos, on the other hand, as the only a main line less than a year of the "new" chain, its development is rapid, let us see the domestic new chain of hope, in the future we hope to see more high quality domestic project, relying on the support of national policy and technology, to create a good reputation in the industry and promote the benign development of industry.
