Blockchain Firm Digital Asset Integrates Smart Contract Language With Hyperledger

Published at: April 16, 2019

Blockchain software firm Digital Asset will integrate their smart contract language DAML with Hyperledger Sawtooth, a modular platform for distributed ledgers. Digital Asset announced the development in a blog post on April 16.

In the post, Digital Asset revealed that it has begun working with Hyperledger members, Blockchain Technology Partners (BTP), in order to integrate the Digital Asset Modeling Language (DAML) runtime with Hyperledger Sawtooth, which is a modular platform for building, deploying, and running distributed ledgers like blockchains.

The company explained that a number of the Hyperledger Sawtooth characteristics already comply with the DAML team expectations. “Hyperledger Sawtooth’s Transaction Processor has a very flexible approach towards roles and permissions, for example, and is based on a very natural DLT network topology of fully distributed peers. DAML is based on a permissioned architecture and Hyperledger Sawtooth can be configured to be permissioned without requiring special nodes,” the post details.

DAML removes smart contracts apart from the ledger by defining an abstraction over implementation details like cryptography and data distribution, which purportedly provides a ledger model accessible through a clearly defined application programming interface (API). DAML applications can be moved from platform to platform without complex rewrites.

Digital Asset first introduced DAML in April 2016, describing it as an expressive language designed for financial institutions to model and execute agreements through distributed ledger technology (DLT). Earlier this month, Digital Asset open sourced the DAML, making it freely available under the Apache 2.0 open source license.

Subsequently, the firm partnered with major cloud computing company VMware to integrate the DAML on VMware’s blockchain platform. The development will purportedly “allow for broader reach and support as a combined offering.”

Digital Asset also announced a collaboration with the International Swaps and Derivatives Association (ISDA) to develop a new tool that can support the use of smart contracts for derivatives trading.
