智能合同语言DAML现在可以在企业区块链R3的Corda上开发应用程序

2020-7-28 12:45

 

今天,数字资产宣布其跨平台智能合同语言DAML现在可以在企业区块链R3的Corda上开发应用程序。


Digital Asset最近宣布了一项来自VMware的投资,VMware从Salesforce、三星(Samsung)和IBM等大公司获得了1.5亿美元的总投资。它还拥有大量资本市场支持者,包括澳大利亚证券交易所ASX、花旗、DTCC、摩根大通和高盛。


DAML是为业务工作流设计的,已经与其他主要的区块链合作,如Hyperledger Fabric, Sawtooth和Besu, VMware区块链以及亚马逊的QLDB和多个数据库。尽管DAML语言是开源的,但是集成通常不是。


Corda之前集成了DAML作为一个原型,但后来转向了生产版本,今天它宣布智力和DataArt将成为集成伙伴。这个集成同时适用于开源和企业版本的Corda。到目前为止,Corda的所有智能合同应用程序都是用Java或Kotlin编写的。


DAML的主要好处之一是可以使用几乎任何许可的分布式账本技术(DLT)开发应用程序,并且区块链或DLT平台可以在以后进行切换,而不需要更改应用程序。正如今天早些时候报道的,Digital Asset的目标是使DAML能够跨区块链协议实现可互操作的应用程序。


“DAML是我们所见过的为企业开发分布式应用程序的最简单和最健壮的方法,”智库副总裁Thomas Bohner说。公司在金融领域拥有众多客户,如Belfius、Capital One、KBC、SWIFT、Euroclear和ASX。为基于Corda的贸易融资平台Contour和DAML提供对Hyperledger面料的集成支持。此外,它还有催化剂区块链平台,可以快速部署区块链。


DAML的应用程序开发方法不考虑账本,这使得跨多个平台构建、部署、更改和共享新服务变得更加容易。互操作性是至关重要的,而DAML为我们提供了机会,为一个急需的互联商业环境铺平了道路,”DataArt的Denis Baranov说。


当被问及为什么Digital Asset选择这些集成合作伙伴时,他们的回答是,这些是客户提到的希望采用Corda和DAML的公司。


数字资产首席技术官Shaul Kfir在接受Ledger Insights采访时补充了R3。“我很喜欢R3的架构决策,他们有很好的用户基础,”Kfir说。“我们从使用DAML和Corda的客户那里得到了非常积极的早期反馈。以Corda作为基础设施,以DAML作为运行应用的方式,这是一个非常强大的组合。”


在Corda上的DAML目前已经为开发人员提供了产品版本,预计将在第三季度发布,企业特性将在2020年底发布。

 

Today Digital Asset announced that its cross-platform smart contract language DAML is now available for developing applications on enterprise blockchain R3’s Corda.

Digital Asset recently announced an investment from VMware, which added to its total funding of more than $150 million from big names such as Salesforce, Samsung and IBM. It also has plenty of capital markets backers, including Australian Securities Exchange ASX, Citi, DTCC, JP Morgan and Goldman Sachs. 

DAML is designed for business workflow and already works with other major blockchains such as Hyperledger Fabric, Sawtooth and BesuVMware Blockchain as well as Amazon’s QLDB and multiple databases. Although the DAML language is open source, the integrations generally are not.

Corda was previously integrated with DAML as a prototype but has since moved towards a production version, and today it was announced IntellectEU and DataArt will be integration partners. The integration is both for the open source and enterprise versions of Corda. Until now all smart contract applications for Corda were written in Java or Kotlin.

One of the major benefits of DAML is an application can be developed using almost any permissioned distributed ledger technology (DLT), and the blockchain or DLT platform can be switched later without needing to change the application. As reported earlier today, Digital Asset aims to make DAML enable interoperable applications across blockchain protocols. 

“DAML is the easiest and most robust way to develop distributed applications for businesses that we have seen,” said Thomas Bohner, VP IntellectEU. The company has numerous clients in the finance sector, such as Belfius, Capital One, KBC, SWIFT, Euroclear and ASX. It is providing integration support for Corda based trade finance platform Contour and DAML for Hyperledger Fabric. Additionally, it has its Catalyst Blockchain Platform for speedy blockchain deployment.

“DAML’s ledger-agnostic approach to application development makes it easier to build, deploy, change and share new services across multiple platforms. Interoperability is paramount and DAML affords us that opportunity, paving the way towards a much-needed interconnected business environment,” said Denis Baranov of DataArt.

When asked why Digital Asset chose these integration partners, the response was that these were the firms mentioned by clients that wanted to adopt Corda with DAML.

Digital Asset CTO Shaul Kfir complemented R3 when Ledger Insights spoke to him. “I’m a fan of the architecture decisions of R3 and they have a good user base,” said Kfir. “We hear early feedback from customers who are using DAML and Corda (which) is very positive. It’s a very powerful mix to have Corda as the infrastructure and DAML as the way of running apps.”

DAML on Corda is currently available for developers with a production version expected in Q3 and enterprise features by the end of 2020.
