The national blockchain infrastructure BSN created by the National Information Center, China Mobile, China UnionPay and Beijing Red Date Technology chose DAML created by Digital Asset as the smart contract development language.

Beijing Jujube Technology and Digital Asset announced a cooperation agreement on the integration of DAML smart contract technology and the blockchain service network ( BSN ). As part of the agreement, the smart contract programming language DAML created by Digital Asset will become the standard language for writing distributed applications (DApp) in the BSN ecosystem. The two companies will start a rapid pilot work, through the interaction between Hyperledger Fabric and FISCO BCOS under WeBank’s two underlying frameworks to deploy DApps and demonstrate the process of DAML application deployment, and integrate DAML applications into In the core framework of BSN, this goal is planned to be completed by November 2020 . At the same time, it is expected that in 2021, the goal of allowing developers to use DAML for smart contract development on BSN is generally achieved.

Currently, each underlying blockchain framework has its own smart contract development language, which means that DApps developed by different underlying frameworks cannot interact normally. And BSN provides enterprises with a low-cost blockchain application deployment environment across the underlying framework. With the addition of DAML, developers will be allowed to deploy the DApp by selecting the underlying framework used during development without repeating their own smart contracts without repetitively writing their own smart contracts. The DApp can be deployed on other BSNs. Easy interaction between distributed applications.

BSN is a global blockchain infrastructure jointly initiated by China Mobile, China UnionPay and Beijing Jujube Technology by the top-level plan of the National Information Center. It aims to allow developers and enterprises to create and access a new generation more efficiently under a unified standard. Distributed application. The four sponsors started the BSN project as early as 2018, and BSN is currently China’s largest blockchain infrastructure network.

DAML is an advanced open source smart contract language and toolkit for developing DApps that cross data islands and trust boundaries. At the same time, DAML is the only smart contract technology that can run seamlessly on multiple platforms. In addition to the upcoming cooperation with BSN, DAML has integrated Vmware blockchain, Corda, Hyperledger Fabric, Sawtooth and Besu, PostgreSQL, Amazon’s QLDB and its native cloud Aurora database. Earlier this year, WeBank announced a plan to integrate DAML with FISCO BCOS. FISCO BCOS is one of the core underlying frameworks that BSN can use.

“BSN is China’s largest blockchain infrastructure project,” said Mr. Shan Zhiguang, chairman of the blockchain service network BSN Development Alliance. “From the very beginning, our goal was to break the information island of the blockchain and create a An open, interoperable and accessible ecosystem. This is an exciting moment in the history of China’s blockchain development. We are honored to integrate Digital Asset’s DAML into our ecosystem to promote the prosperity and development of BSN .”

“We are very happy that Digital Asset can support BSN,” said Ms. Tan Min, who works in China Mobile and serves as the secretary-general of the blockchain service network BSN Development Alliance. “BSN needs a unified smart contract programming language for the developer community to use, and The open source DAML smart contract technology is the perfect choice. The global mainstream companies and industry associations unanimously choose DAML smart contract technology, which left a deep impression on us.”

“BSN is a transformative measure that will shape the future of blockchain in China and even the world,” said Mr. Zhou Yu of China UnionPay. “We have high hopes for the success of the DAML pilot. The subsequent official production will become a driving force for BSN to continue. One of the important driving forces for rapid development.”

“Our purpose of creating BSN is to provide blockchain developers with a low-cost and efficient one-stop service for them to build and deploy distributed applications on the blockchain framework of their choice,” Beijing Red Date Technology CEO Mr. He Yifan said, “Nowadays, every blockchain framework has its own supported smart contract language, which makes developers sometimes a headache-once they want to deploy the application to other blockchain frameworks, they must rewrite the application. Therefore, they have to learn a variety of different technologies. By choosing DAML as BSN’s own dedicated smart contract language, our developers will get a seamless and interoperable use of a unified smart contract language between each blockchain s Choice.

“We will actively promote the integration of DAML and FISCO BCOS as part of BSN. We see an excellent opportunity to reach a broader developer community.” said Mr. Fan Ruibin, head of blockchain at WeBank.

“BSN’s vision is consistent with Digital Asset’s,” said Yuval Rooz, Digital Asset’s co-founder and CEO. “There are currently a large number of blockchain frameworks to choose from, and more frameworks will be listed in the future. Create a low Cost and interoperable tools to unify these underlying frameworks are the key to promoting the global popularization of blockchain. BSN has deployed and operated more than 130 city nodes in China, and its development is unstoppable. Through the integration with DAML, BSN will have its own Standard application programming languages ​​and advanced interoperable protocols will further realize our vision.”

Since its commercial launch in April 2020, BSN has quickly become one of the world’s largest and fastest-growing enterprise-level blockchain ecosystems. Currently, more than 1,000 blockchain applications have been deployed and used on BSN by Chinese enterprises and government agencies. More than 130 public city nodes deployed by BSN connect more than 80 cities in mainland China. At the same time, BSN has deployed 8 public city nodes worldwide. By 2021, BSN is expected to complete the adaptation of 10 permission chain frameworks and more than 50 public chain blockchain frameworks for developers around the world to use BSN at low cost.
