数字资产的DAML支持中国区块链服务网络的区块链互操作性

2020-9-15 11:32

 

今天,中国区块链服务网络(BSN)的创始人之一Digital Asset和Red Date Technology宣布了将DAML智能合同语言与BSN整合的计划。此外,DAML将成为开发分散应用程序(dApps)的“独家标准”。DAML的关键特性是它可以在大多数企业区块链和以太坊上工作。但是这个声明更进一步地将DAML用于dApps, dApps可以在使用不同区块链协议的网络之间互操作。


BSN由中国国家信息中心(SIC)支持,是一个低成本、可访问的入口,最初旨在帮助个人和小企业采用区块链。有中国版和全球版。前者只支持企业区块链,最初是Hyperledger Fabric和中国的FISCO BCOS。此外,global one还集成了大量的公共区块链,包括Ethereum、EOS、Tezos、Nervos、NEO和IRISnet。


“如今,每个区块链协议都有自己内置的智能契约语言;但这对开发人员来说很困难,他们需要学习很多不同的技术才能起步,而且如果他们想部署到一个不同的区块链上,就必须彻底重写他们的应用程序。”“通过选择DAML作为BSN本身的独家智能契约语言,我们的开发人员将获得在每个区块链之间无缝地、可互操作地使用一种统一的智能契约语言的选择。”


BSN的创始成员有SIC、中国移动、中国银联和红枣科技。该网络已经在中国各地拥有130个节点。


“BSN是中国最大的区块链基础设施倡议,”国家信息中心和BSN发展协会主席单志光在关于DAML的声明中说。“从一开始,我们的目标就是打破区块链的竖井,创建一个开放的、可互操作的、所有人都可以访问的生态系统。”


几个月前,腾讯旗下的微众银行宣布将把DAML与FISCO BCOS(中国的超级账本结构)整合在一起。微众银行计划将这项工作贡献给BSN。到今年11月,将有一个在Hyperleger Fabric和FISCO BCOS之间跨网络互操作DAML应用程序的试点。该解决方案预计将于2021年全面推出。


最后一点是一个重要的区别。目前,DAML在许多区块链上运行,但在每一个案例中,智能契约都在单个网络上运行。两个月前,Digital Asset提出了使用DAML实现区块链互操作性的愿景,特别是在资本市场,这是其核心优势之一。这是关于实现与DAML的区块链互操作性的第一个商业声明。


到目前为止,DAML已经集成了VMware区块链,Corda, Hyperledger Fabric, Sawtooth和Besu(为Ethereum)以及多个数据库。


就BSN方面的互操作性而言,他们还计划使用IRISNet基于IRITA的互链服务创建一个互链通信中心,该服务使用Cosmos/IRIS SDK,这是一种更好的公共网络互操作性解决方案。

政治


与此同时,在此之前,特朗普总统最近在美国禁止了腾讯的微信。BSN中方使用微信支持,全球版使用Telegram。FISCO BCOS是由腾讯及其合作伙伴微众银行(WeBank)以及其他公司共同创立的。


从数字资产的角度分析,BSN非常适合DAML的交叉账本和互操作性的愿景。从实用主义的角度来看,这是一个巨大的胜利。数字资产并不是唯一参与BSN的美国公司。与中国移动、中国电信和百度AI云一样,谷歌云和亚马逊的AWS也托管节点。


微信禁令和英国禁止使用华为的5G几乎是同一时间。当时,我们提出了BSN是否会在某个时候出现在雷达上的问题。


从中国的角度来看,也存在一些问题。许多关于区块链的中国演讲和论文都一再提到在中国发展技术的必要性。这是开发FISCO BCOS的原因之一。对本土技术的渴望在一定程度上是对特朗普过去几年的举措的回应,也是对成为技术强国的渴望。


但谢天谢地,目前区块链还不是中美拔河的一部分,这看起来是一个很有希望的合作。

 

Today Digital Asset and Red Date Technology, one of China’s Blockchain-based Service Network (BSN) founders, announced plans to integrate the DAML smart contract language with BSN. Additionally, DAML will become the “exclusive standard” for developing decentralized applications (dApps). The key feature of DAML is that it can work on most enterprise blockchains and Ethereum. But this announcement takes it a step further using DAML for dApps that can interoperate between networks using different blockchain protocols.

Backed by the State Information Center of China (SIC), the BSN is a low-cost, accessible onramp originally targeted to aid individuals and small businesses to adopt blockchain. There is a Chinese version and a global one. The former only supports enterprise blockchains, initially Hyperledger Fabric and China’s FISCO BCOS. And the global one is additionally integrated with numerous public blockchains, including Ethereum, EOS, Tezos, Nervos, NEO and IRISnet.

“Today, each blockchain protocol has its own built in smart contract language; but that makes it difficult for developers, who need to learn many different technologies to get started, and must rewrite their application entirely if they want to deploy to a different blockchain,” said Yifan He, CEO of Red Date. “By selecting DAML as the exclusive smart contract language of the BSN itself, our developers will gain the choice of using one unifying smart contract language seamlessly and interoperably across every blockchain.”

BSN’s founding members are SIC, China Mobile, China UnionPay and Red Date Technology. The network already has 130 nodes across China.

“BSN is the largest blockchain infrastructure initiative in China,” said Zhiguang Shan, of State Information Center and Chairman of the BSN Development Association on the DAML announcement. “Since its inception, our goal has been to break down blockchain silos and create an ecosystem that is open, interoperable and accessible to all.”

A few months ago, it was announced that Tencent associate WeBank would integrate DAML with FISCO BCOS, China’s answer to Hyperledger Fabric. WeBank plans to contribute that work to BSN. By November this year, there will be a pilot for a DAML application interoperating across networks between Hyperleger Fabric and FISCO BCOS. The solution is expected to be generally available in 2021.

That last point is an important distinction. Right now, DAML runs on many blockchains, but in each case, the smart contracts function on a single network. Two months ago, Digital Asset laid out its vision of using DAML for blockchain interoperability, particularly for capital markets, one of its core strengths. This is the first commercial announcement about implementing blockchain interoperability with DAML.

So far, DAML has been integrated with VMware Blockchain, Corda, Hyperledger Fabric, Sawtooth and Besu (for Ethereum) as well as multiple databases.

In terms of interoperability on the BSN side, there are also plans to create an Interchain Communications Hub using IRISNet’s IRITA based interchain service, which uses the Cosmos/IRIS SDK, one of the better know interoperability solutions for public networks.

Politics

Meanwhile, this announcement follows President Trump’s recent ban on Tencent’s WeChat in the United States. The Chinese side of BSN uses WeChat for support, but the global version uses Telegram. And FISCO BCOS was co-founded by Tencent and its associate WeBank as well as others.

Analyzing the move from Digital Asset’s perspective, the BSN fits very neatly with DAML’s cross ledger and interoperability vision. From a pragmatic point of view, this is a big win. It’s also not as if Digital Asset is the only U.S. company involved in the BSN. Google Cloud and Amazon’s AWS also host nodes alongside China Mobile, China Telecom and Baidu AI Cloud. 

The WeChat ban was around the same time as the U.K. ban on using Huawei for 5G. At the time, we raised the question about whether the BSN might not get on the radar at some point. 

From a Chinese angle, there are also issues. Many Chinese talks and papers about blockchain repeatedly raise the need to develop technology within China. That was one of the reasons for developing FISCO BCOS. The desire for homegrown technology is partly in response to Trump’s moves over the last few years and a desire to be a technology powerhouse.

But for now, thankfully, blockchain is not part of the U.S. China tug-of-war, and this looks like a promising collaboration.
