Project
Hyperledger Besu
Current Plans
- Migration to Java 17
In the 22.7.x cycle Besu will move to Java 17 as the required JVM. - Paris Upgrade
Paris will ship when it's ready, but final preparations are at hand. - 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 work stream to specifically focus on developer experience, allowing prioritization of issues alongside feature work.
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

Functional improvements included in these releases:
London Hard Fork - Launched on August 5th
The team has been preparing Hyperledger Besu to be compatible with the next Ethereum hard fork, London. The London Hard Fork included:
- EIP-1559: Fee market change for ETH 1.0 chain
- EIP-3198: BASEFEE opcode
- EIP-3529: Reduction in refunds
- EIP-3541: Reject new contracts starting with the 0xEF byte
- EIP-3554: Difficulty Bomb Delay to December 1st 2021

Many of the maintainers have been focusing on continuing mainnet compatibility work and adding cross-client support for GoQuorum within the Besu codebase. Specifically, the team was dedicated towards the London Hard Fork. Significant contributions have come from Hedera Hashgraph, who are working on integrating the Besu EVM into future releases of Hedera's network. Hedera's focus is on performance and utility.
Current Plans
- 21.10.0 Release: The project team remains currently working towards its 21.10.0 Release, scheduled for October 2021. The 21.10.0 Release is expected to include the following features:
- Performance improvements to prepare for the Merge
- Optimistic Besu: The team will be exploring different options for supporting use of the Besu EVM for Optimistic Rollups
- Permissioning features will be extended to include more granular account permissioning for different transaction and interaction types.
- EVM Library: the core EVM component will be separated as a stand alone library, suitable for use outside of an integrated mainnet client.
- Eth 1 to Eth 2 Merge: Some of the Besu team is participating in a Eth1 and Eth2 contributor meet-up the week of October 2nd to discuss in detail the plans for the Eth 1 to Eth2 Merge, which moves Ethereum from Proof of Work to Proof of Stake. We anticipate this body of work to take up a significant amount of the team's time in the coming months.
- Grace Hopper Open Source Day: The Besu project is participating in the Grace Hopper Open Source Day and we are excited to share our project with new joiners there.
- Community Engagement: Similar previous quarters, Besu is also continuing to engage with its community and grow the diversity and decentralization of its maintainer and contributor base. We have added about 15 new good first issues so we encourage the community to give them a try.

Functional improvements in these releases include:
Berlin Network Upgrade - Released
The team completed work to ensure Hyperledger Besu was compatible with the Ethereum hard fork, Berlin, which occurred on April 15th. The Berlin Network upgrade included several improvements to the Ethereum mainnet, such as the addition of subroutines to the EVM, the introduction of “transaction envelopes”; which make it easier for Ethereum to support several different kinds of transactions, and changes in gas costs to increase the security of the network.
London Hard Fork - Scheduled for July 14th
The team has been preparing Hyperledger Besu to be compatible with the next Ethereum hard fork, London. The London Hard Fork includes:
- EIP-1559: Fee market change for ETH 1.0 chain
- EIP-3198: BASEFEE opcode
- EIP-3529: Reduction in refunds
- EIP-3541: Reject new contracts starting with the 0xEF byte
