Arbitrum Nitro v3.1.3 Release Candidate 2

This release is available as a Docker image on Docker Hub at offchainlabs/nitro-node:v3.1.3-rc.2-4483e77

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:v3.1.3-rc.2-4483e77-validator which has the extra script /usr/local/bin/split-val-entry.sh as the entrypoint.

Arbitrum Nitro v3.1.2

This release is available as a Docker image on Docker Hub at offchainlabs/nitro-node:v3.1.2-309340a

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:v3.1.2-309340a-validator which has the extra script /usr/local/bin/split-val-entry.sh as the entrypoint.

It's important that you only run the nitro node against trusted databases. If you want to use an untrusted database, you can first remove the wasm directory if it exists (it might be inside the a folder called nitro). Otherwise, the database may have malicious unvalidated code that can result in remote code execution. This is also mitigated by running the Arbitrum Nitro node inside docker.

What's Changed

This release fixes a crash in v3.1.1 for chains imported from Arbitrum Classic, i.e. Arbitrum One. For details on the v3.1.1 release, see the v3.1.1 release notes.

Internal Highlights

• Return false if nil is passed to IsNotExistError: #2616

Full Changelog: v3.1.1...v3.1.2

Arbitrum Nitro v3.1.1

Use v3.1.2 instead

This release has an issue preventing successful startup on databases with an Arbitrum Classic message lookup table such as most Arbitrum One databases. This is fixed in v3.1.2.

Release notes

This release is available as a Docker image on Docker Hub at offchainlabs/nitro-node:v3.1.1-b26e84e

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-b26e84e-validator which has the extra script /usr/local/bin/split-val-entry.sh as the entrypoint.

If you want to use an untrusted database, you can first remove the wasm directory if it exists (it might be inside the a folder called nitro). Otherwise, the database may have malicious unvalidated code that can result in remote code execution. This is also mitigated by running the Arbitrum Nitro node inside docker.

What's Changed

This release significantly improves Stylus support including EVM-like tracing, adds support for fast confirmation, adds experimental PathDB support, improves Anytrust DAS stability, improves validator stability, adds additional metrics, and improves tracing support.

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.
• --execution.sequencer.sender-whitelist, --node.batch-poster.data-poster.replacement-times, --node.batch-poster.data-poster.blob-tx-replacement-times, --node.staker.data-poster.replacement-times, and --node.staker.data-poster.blob-tx-replacement-times were all changed from strings with commas separating their components to arrays of strings. This shouldn't affect CLI usage, but will mean that JSON configuration of these values needs to be changed from strings to arrays.
• --init.reset-to-message has been removed and replaced with --init.reorg-to-message-batch which will reorg to the batch at or before the requested message number. There's also --init.reorg-to-block-batch which takes a block number and --init.reorg-to-batch which takes a batch number.

Metrics Changes

• arb/sequencer/condtionaltx/* metrics were renamed to arb/sequencer/conditionaltx/* and arb/txprechecker/condtionaltx/* metrics were similarly renamed to arb/txprechecker/conditionaltx/* to fix typos

Experimental PathDB Support

This release adds experimental PathDB support with --execution.caching.state-scheme=path. However, this has not been thoroughly tested, and as such we don't recommend running it in production at this time, as it may have database corruption issues or produce incorrect results. It'll also require a resync with a new database.

User-facing Improvements

• Add option to enable fast confirmation: #2434
  • Try to fast confirm past nodes too: #2520
  • Disable fast confirmations by default: #2579

• Move TxLookupLimit override into ParseNode: #2481
• Check all "not found" errors (fixes default data poster config): #2532
• Fixes block hash retrieval in PopulateFeedBacklog: #2551

What's Changed

This release contains various validation fixes compared to the last beta release.

However, please note that Stylus validation is still incompatible in this version with previous databases. As a workaround, you can remove the wasm folder from your database if you're running a Stylus enabled chain (e.g. Arbitrum Sepolia).

Arbitrum Nitro v3.1.0

This release is available as a Docker image on Docker Hub at offchainlabs/nitro-node:v3.1.0-7d1d84c

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:v3.1.0-7d1d84c-validator which has the extra script /usr/local/bin/split-val-entry.sh as the entrypoint.

What's Changed

This release adds support for ArbOS 31, which is a required upgrade for Arbitrum Sepolia by Tuesday, July 23nd, 2024 13:00 ET, and should the on-chain vote pass, will be required in approximately a month for Arbitrum One and Arbitrum Nova. This release also improves the Anytrust data availability system.

Configuration Changes

• The --p2p.* options were removed, as the P2P system doesn't do anything in nitro yet and was causing incompatibilities loading Arbitrum Classic blocks.
• If you're running a batch poster, non-default Anytrust DAS signermasks are no longer supported. The signermask must now be consecutive powers of two for each signer in the keyset. If this is not the case, a new keyset must be generated to be compatible with this version's batch poster. As part of this change, the signermask field in DAS keyset backends is now ignored and no longer required.
• The Anytrust DAS local-db-storage is deprecated in this release, and will soon be removed. To migrate to the new filesystem database, use --data-availability.migrate-local-db-to-file-storage

User-facing Improvements

• Make DAS backends and keyset easier to configure, fixes: NIT-2594: #2427
• Anytrust DAS filestore trie layout migrator and expiry: #2385
• Deprecate local-db-storage, add migration opt: #2409
• Don't post a batch that would cause a reorg due to being near the layer 1 minimum block or timestamp bounds: #2411
• Support auto-detection of database engine (pebbledb vs leveldb): #2447
• Add iostat system metrics: #2398
• Metric for any das.Aggregator Store errors: #2410
• Add GAS opcode to Stylus tracing, and after producing a fake EVM GAS opcode in a trace, add a POP afterwards: #2382
• Add LOG opcodes to Stylus tracing: #2452
• Export redis-url for valnode: #2464
• Drop nitro p2p config options: #2462
  • Fix disabling P2P: #2485

ArbOS 31
