OffchainLabs/nitro v3.1.1-rc.1

Arbitrum Nitro v3.1.1 Release Candidate 1

on GitHub

This release is available as a Docker image on Docker Hub at offchainlabs/nitro-node:v3.1.1-rc.1-75f3aaf

This Docker image specifies default flags in its entrypoint which should be replicated if you're overriding the entrypoint: /usr/local/bin/nitro --validation.wasm.allowed-wasm-module-roots /home/user/nitro-legacy/machines,/home/user/target/machines

If you're running a validator without a split validation server (this will be true of most validators), you should instead use the image offchainlabs/nitro-node:v3.1.1-rc.1-75f3aaf-validator which has the extra script /usr/local/bin/split-val-entry.sh as the entrypoint.

What's Changed

This release fixes the validator, adds a tool to convert leveldb databases to pebbledb, and adds EVM-like tracing for Stylus programs compared to the last beta release.

Configuration Changes

• --execution.tx-pre-checker.strictness now defaults to 20 instead of 0, meaning that transactions sent to the node will have some basic checks applied (e.g. nonce isn't too low, account has enough balance, maxFeePerGas is high enough, etc.) before being forwarded to the sequencer. This will help reduce issues with the sequencer rate limiting intermediate nodes due to an influx of invalid transactions.
