v0.6.0

Important

This release is a hard fork. At 2026-07-28 06:00:00 UTC (1785218400000 ms) the Morph mainnet upgrades its consensus to a single high-performance sequencer.
Every node must upgrade to v0.6.0 before this time, or it will fall out of consensus.

Upgrade notes

• Start every node with --mainnet — selects the mainnet configuration and the sequencer upgrade time. Without it the node will not pick up the fork boundary.
• Configure the L1 Beacon RPC endpoint (newly required, eth namespace) via either:
  • CLI flag: --l1.beaconrpc <BEACON_RPC_URL>
  • Env var: MORPH_NODE_L1_ETH_BEACON_RPC=<BEACON_RPC_URL>

Highlights

High-Performance Sequencer — block production moves from multi-node PBFT to a single high-performance sequencer, removing per-block BFT consensus overhead for faster blocks and higher throughput. The sequencer produces blocks while all other nodes follow as full nodes and verify against L1. This release also adds a sequencer-mode metric and defaults the local devnet to the single-sequencer setup.
