Digital Asset announced the general availability of Daml 2.0, the newest version of Digital Asset’s multi-party application platform. This version makes it easier than ever to build and deploy best-in-class, multi-party applications. Daml 2.0 includes Canton, a privacy-enabled distributed ledger that is enhanced when deployed with complementary blockchains. Canton ensures strong privacy and compliance — unique among multi-party systems — while synchronizing transactions across any supported blockchain or database. For example, a Daml asset can now be safely delivered on Hyperledger Besu while the payment can be made using a different Daml asset on Hyperledger Fabric, in a single, atomic transaction.

Today, businesses are increasingly using multi-party applications to drive efficiency and innovation by automating processes and delivering new products and services. However, the lack of reliable privacy protecting platforms means that multi-party applications too often languish in the proof-of-concept phase or fall behind a walled garden — a siloed blockchain implementation with limited reach. Additional challenges exist when connecting these applications that run on different blockchains or databases, requiring complex workarounds that introduce risk and issues with data consistency and privacy. Consequently, businesses have been unable to realize the full potential of blockchain, distributed ledger technologies, and the multi-party applications that can create novel products and experiences.
