DAML was selected as the dedicated smart contract language for the blockchain service network BSN

The national blockchain infrastructure BSN created by the State Information Center, China Mobile, China UnionPay and Beijing Jujube Technology has chosen DAML (Unified Smart Contract) created by Digital Asset.

September 14, 2020, Beijing time - Beijing Jujube Technology and Digital Asset announced a cooperation agreement on the integration of DAML smart contract technology and Blockchain Service Network (BSN). As part of the agreement, DAML, the smart contract programming language created by Digital Asset, will become the standard language for writing distributed applications (DApps) within the BSN ecosystem. The two companies will embark on a rapid pilot project to demonstrate the process of DAML application deployment through the interoperability between DApps deployed on the two underlying frameworks of Hyperledger Fabric and WeBank's FISCO BCOS, and integrate DAML applications into In the core structure of BSN, this goal is planned to be completed by November 2020. At the same time, it is expected that the goal of enabling developers to use DAML for smart contract development on BSN will be generally achieved in 2021.

FundamentalVR, a startup in the medical metaverse, completed $20 million in financing: On August 11, FundamentalVR, a startup in the medical metaverse, announced the completion of a $20 million round of financing. This round of financing was led by EQT Life Sciences and participated by Downing Ventures. FundamentalVR's immersive simulation platform combines virtual reality (VR) and mixed reality (MR) applications to help doctors train surgery in a virtual environment. The company has developed a dedicated hardware engine and interface to support VR headsets such as Oculus Quest and HTC Vive. And MR platforms like Holo Lens and Magic Leap.

At present, each blockchain underlying framework has its own smart contract development language, which means that DApps developed by different underlying frameworks cannot interact normally. BSN provides enterprises with a low-cost blockchain application deployment environment across the underlying framework. With the addition of DAML, it will allow developers to deploy the DApp by selecting the underlying framework used for development in BSN without repeatedly writing their own smart contracts. Easy interaction between distributed applications.

ADAMoracle Global Node Network Public Beta Officially Opened: On September 13, ADAMoracle announced that it had completed the internal test and officially opened the global node network public beta. It joined forces with global wide-area nodes to conduct pressure challenge tests on the oracle network, trying to promote the improvement and development of wide-area node technology. Innovate and consolidate the ecological foundation of ADAMoracle oracle machine.

ADAMoracle, as a decentralized oracle machine that supports wide-area node price feeding, aims to build a safe, credible, accurate, sybil-proof, and self-maintaining decentralized oracle network, replacing traditional oracle machines with Turing intelligence , to create a forward-looking and innovative "everyone can participate in price feeding" oracle machine 3.0 era.

A few days ago, the ecological governance token ADAM has been launched on DODO, and the USDT/ADAM exchange has been opened, and the opening of the wide-area node network public test will promote the leapfrog development of ADAMoracle oracle ecological construction. [2021/9/13 23:21:51]

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

Adamant Capital founder: U.S. bitcoin investors may face tax problems: On the morning of August 5, Adamant Capital founder Tuur Demeester tweeted that it is difficult to hold liquid assets. Bitcoin investors in the U.S. might imagine an IRS clerk standing in their yard, holding up a large sign saying how much capital gains tax they would have to pay on the sale of their Bitcoins.

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

A breakout of this range could trigger another parabolic rally. [2020/5/19]

"BSN is the largest blockchain infrastructure project in China," said Mr. Shan Zhiguang, chairman of the BSN Development Alliance, a blockchain service network. An open, interoperable and accessible ecosystem. This is an exciting moment in the history of China's blockchain development. We are honored to be able to integrate Digital Asset's DAML into our own ecosystem to promote the prosperity and development of BSN .”

"We are very pleased that Digital Asset can support BSN," said Ms. Tan Min, who works in China Mobile and serves as the secretary-general of the BSN Development Alliance of the blockchain service network. "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. We are deeply impressed by the unanimous choice of DAML smart contract technology by mainstream companies and industry associations around the world.”

"BSN is a transformative initiative that will shape the future of China's and even the world's blockchain," said Mr. Zhou Yu of China UnionPay. One of the important drivers of rapid development."

"Our purpose in creating BSN is to provide a low-cost, efficient one-stop service for blockchain developers to build and deploy distributed applications on the blockchain framework of their choice," said Beijing Red Date Technology CEO Mr. He Yifan said, "Nowadays, each blockchain framework has its own smart contract language, which sometimes makes developers a headache—once they want to deploy applications to other blockchain frameworks, they must rewrite the application. So they have to learn a variety of different technologies.By choosing DAML as BSN's own dedicated smart contract language, our developers will have a unified smart contract language that can be used seamlessly and interoperably between each blockchain s Choice.

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

"BSN's vision is aligned with Digital Asset's," said Yuval Rooz, co-founder and CEO of Digital Asset. "There are currently many 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 Our own standard application language and advanced interoperable protocols will further realize our vision."

Since its commercial launch in April 2020, BSN has quickly become one of the largest and fastest-growing enterprise-level blockchain ecosystems in the world. At present, more than 1,000 blockchain applications have been deployed and used by Chinese enterprises and government agencies on BSN. 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 around the world. By 2021, BSN is expected to complete the adaptation of 10 permissioned chain frameworks and more than 50 public chain blockchain frameworks for developers around the world to use on BSN at low cost.
