Berachain Balancer Upgrade #2

This upgrade to Berachain Mainnet restores some functionality to BEX.

WARNING

All node operators, whether hosting an RPC or running a validator, must upgrade their execution client to the versions below in order to continue following the chain.

INFO

Hardfork Date: Wednesday, November 12 at 16:00 GMT / 11:00 EST.

All nodes are expected to have their binaries and respective genesis files updated before this date, or risk having their node stop working.

Upgrade Details

Berachain has released standalone executables and Docker images for Linux ARM and AMD64 architectures for both Bera-Reth and Bera-Geth. All clients can be easily compiled for other systems and architectures within a few minutes; please review their respective READMEs for details.

New genesis files are required for Bera-Reth/Geth.

No configuration changes are required.

Upgrade Instructions

TIP

If you duplicate your installation to test the upgrade—which is recommended—do not copy these identity files, as this could interfere with your production node's peering:

• Bera-Reth: discovery_secret
• Bera-Geth: nodekey
• Beacon-Kit: priv_validator_key.json

WARNING

If you compile your own build, do so against the recommended release branches.

1. Stop all clients.
2. Install the recommended release version of Bera-Geth or Bera-Reth, linked below, in place.
3. Install the new Reth/Geth genesis files linked below, and verify the hash with md5sum <file>. Then:
   • Bera-Reth: Overwrite $RETH_DATA/genesis.json.
   • Bera-Geth: No additional steps are required.
4. Start all clients.

TIP

Previous instructions specified a geth init step. This is no longer necessary.

If you performed a geth init step and received a "mismatching Prague3 fork" warning, it can safely be ignored.
