Open Source DLT Momentum Accelerates

The number of open source distributed ledger project continues to increase. Here’s a quick roundup of what’s out there, or coming soon.

OK, I guess there is Bitcoin and Ethereum in the permissionless world. Also, of note are:

• Fabric — Incubated by the Linux Foundation’s Hyperledger Project. It is based on significant early contributions from IBM and Digital Asset Holdings.
• Sawtooth Lake — Also incubated by the Hyperledger Project, it was submitted by Intel. It was originally developed to explore scalability, security, and privacy issues.
• Corda — Developed by R3 CEV, it will be submitted to the Hyperledger Project on November 30.
• Quorum — Developed by JPMorgan Chase, it is a fork of Ethereum but suitable for both permissionless and permissioned blockchains. JPMC says it plans to open source it.
• Chain Core Developer Edition — an open source version of its enterprise blockchain product. It can be run on a test network operated by Chain, Microsoft and IC3.
• Iroha — another distributed ledger being incubated by the Hyperledger Project, Iroha was developed by Japan’s Soramitsu and is targeted at C++ developers and mobile applications.

​Also, Digital Asset Holdings is planning to open source its Digital Asset Markup Language (DAML) for smart contracts, and is also suggesting that its Global Synchronization Log — a component of its own distributed ledger platform — might find a use within one or more of the Hyperledger Project’s developments.
