Consensus V20

This release signifies a WASM fraud proof consensus version, and is not a good version to run a node on

WAVM Module Root: 0x8b104a2e80ac6165dc58b9048de12f301d70b02a0ab51396c22b4b4b802a16a4

This consensus release supports ArbOS 20, which includes support for EIP-4844 based blob batch posting to L1 and support for Cancun execution layer changes on Arbitrum chains, such as EIP-5656 MCOPY and EIP-1153 TSTORE. For more details, see the ArbOS 20 Arbitrum DAO proposal: https://forum.arbitrum.foundation/t/aip-arbos-version-20-atlas/20957

Full Changelog: consensus-v11...consensus-v20

v2.2.4

This release is available as a Docker image on Docker Hub at offchainlabs/nitro-node:v2.2.4-8517340

What's Changed

This release fixes an issue querying Arbitrum Classic transactions and uses the current timestamp as block.timestamp for gas estimation by default.

User-facing Improvements

• Use current timestamp for "pending" block tag instead of last block timestamp, e.g. in eth_estimateGas: OffchainLabs/go-ethereum#286
• Add an option for the inbox reader to only read safe or finalized L1 blocks: #2080
• Add a CLI option for the RPC “finalized” and "safe" block to wait for the block validator to complete: #2086

Internal Highlights

• Fix ArbitrumLegacyTxData decoding: OffchainLabs/go-ethereum#288
• Pull in geth changes to parse ABI errors: #2121

Full Changelog: v2.2.3...v2.2.4

Arbitrum Nitro v2.2.3

This release is available as a Docker image on Docker Hub at offchainlabs/nitro-node:v2.2.3-17468a8

What's Changed

This release improves L3 support and fixes other miscellaneous issues.

Incompatibility with older parent chain RPCs

If you get an error similar to the following on startup:

ERROR[...] failed to get on-chain WASM module root  err="execution reverted: NO_FUNC_SIG"

That likely indicates that your parent chain execution client does not support the input field for calldata for eth_call and eth_estimateGas and needs updated. Previously, this JSON field was called data.

User-facing Improvements

• Add option to recreate missing states in archive node: #2114
• Fix getL1Confirmations on L3s: #2068
• Pause nitro node block validator validation when memory is running low: #2017
• Add support for consensus v11.1 to Dockerfile: #2091

• 4844 inbox reader: #2092 and #2115
• 4844 batch posting support: #2095
  • Disable EIP-4844 batch posting by default for now: #2110
• Support and test ArbOS 20 for development: #2108
• Add missing L1 pricing getters to ArbGasInfo in ArbOS 20: #2109
• Add ArbOS precompile method to get scheduled upgrade: #2112 and #2125

Internal Highlights

• Update go-ethereum to include upstream 1.13.3: #2083 and #2104
• Fix LookupNodeChildren for L3s: #2106
• Fix delayed sequencer finality not recognizing Arbitrum: #2085
• In delayed sequencer, check accumulator against safe block hash: #2105
• Handle long sequencer URLs and fix fetching the list of live sequencers in the sequencer coordinator manager: #2067
• Stop execution node after everything else: #2049
• Prefetch state needed for future block executions by executing them in parallel against old state: #2089
• Add a check that the database chain id matches the config: #2078
• Pass From field from dataposter to external signer: #2037
• Add metrics for relay backlog size and backlog size in bytes: #2048
• Add a metric for memory used by the replay binary WASM in JIT: #2043
• Add option to disable batch poster access lists: #2077
• Log error data when available: #2120
• Add loglevel for ephemeral errors, make data poster nonce ahead of on-chain error an ephemeral error: #2020
• Add context to fatal error messages while connecting to feed: #2082
• Hide error when getting latest confirmed block: #2063

Consensus V11.1

This release signifies a consensus version, and is not necessarily a good version to run a node on

This release is backwards compatible and not required except for use in custom chains that set a custom maximum smart contract code size limit.

WAVM Module Root: 0x68e4fe5023f792d4ef584796c84d710303a5e12ea02d6e37e2b5e9c4332507c4

This backports the following change from consensus v10.3 to consensus v11:

• Make contract size limit configurable: OffchainLabs/go-ethereum#255
