Project Health

Hyperledger Besu remains a strong project with a growing community network of contributors. This quarter the team has focused on the ethereum Mainnet "merge" update, Library refactoring, and Quorum and QBFT compatibility.

There were more releases this quarter than typical due to 4 separate CVEs (one Besu related, three Log4J released).  The 21.10.x line will remain "open" for security updates until 22.1.0 releases.

Overall Activity in the Past Quarter

  • EVM Library
    Work by Hedera Hashgraph has resulted into the separation of the EVM code into a stand-alone library, used by both Hedera and Hyperledger Besu.
  • QBFT
    Interoperable with GoQuorum.
    Validators can be managed via smart contracts - allowing operators to quickly change validators if there is a problem (HA).
  • Mainnet Merge Offsite
    Multiple Besu maintainers attended an offsite in Q4 with all the major consensus and execution layer clients, resulting in an initial proof of concept for the merge.
  • Privacy code hardening
    Addressing tech debt in privacy code. Consolidation of naming ("onchain" privacy deprecated in favour of "flexible" privacy).
  • EVM Performance
    Hedera has worked to roughly triple the throughput of the EVM.
  • JWT Authentication
    Added support for additional (and stronger) authentication algorithms (default was RSA).
  • Logging and Developer experience improvements
    Improvements in response to community feedback. More work to do here.

Current Plans

  • "The Merge"
    Ethereum Mainnet expects to merge the current mainnet chain into the Beacon chain in an event called "Docking" or "The Merge."  This is expected to occur in the first half of 2022. Principal work is mostly done and is expected to finish in Q1.
  • Shanghai Fork
    The first fork after The Merge is expected to add some long overdue EVM improvements, such as the Ethereum Object Format.
  • Developer experience
    Planning to add a workstream to specifically focus on developer experience, allowing prioritization of issues alongside feature work.
  • Tracing APIs
    Parity-style Tracing APIs, requested by Infura 

Maintainer Diversity

Three maintainers were moved to emeritus status due to inactivity (David Mechler, Edward Mack, and Trent Mohay).  Seven new maintainers were added (Daniel Lehrner, Diego López León, Fabio Di Fabio, Frank Li, Jiri Peinlich, Simon Dudley, Taccat Isid)

These four organizations who are maintainers include:

  • ConsenSys Quorum (FKA PegaSys)
  • ETC Cooperative
  • Hedera Hashgraph
  • Splunk 

The maintainers breakdown is:

  • 20% not currently employed by ConsenSys (6 of 29) - This is a slight improvement from prior quarters, however this includes two who have not made contributions since leaving ConsenSys. This will drop to 14% if we do not retain their participation.
