Project Health

We achieved a significant milestone this quarter with the release of Hyperledger FireFly 1.1.

This release makes it possible for FireFly users to deploy multiple blockchain applications connecting to multiple chains, including leading public blockchains like Ethereum, Polygon, Avalanche, Optimism, BNB Chain, Arbitrum, Moonbeam, Fantom and more.

Hyperledger FireFly 1.1 Highlights

  • Web3 Gateway Mode: Use Web3 Gateway Mode to connect to public blockchains including Ethereum, Polygon, Avalanche, Optimism, BNB Chain, Arbitrum, Moonbeam, and Fantom.
  • Public Blockchain Support: Leverage new tools to simplify public use cases, including FireFly Transaction Manager, FireFly Signer, and Enhanced Gateway Support.
  • Consortium Mode: Use Consortium Mode to build multi-party business networks where data needs to be agreed to and shared among the group.
  • Multi-tenant Support: Use new namespace isolation to segregate and configure API security, identity broadcasting, on-chain data indexing, and data sharing.
  • Multiple Instances of Plugins: Use several instances of each type of plugin in a single FireFly node.
  • Pluggable API Security: Enable API Security at several levels and on any service or namespace.

We've also seen an uptick in new community members this quarter participating in discussions in Discord with 87 people versus 71 the previous quarter.

Contributors are very active in the project and since June, excluding merges, we’ve had 18 authors push 513 commits to main.

There are currently 586k lines of code for Hyperledger FireFly across 19 repositories, with a total of 6.4K commits to date.
