all: devnet 3 by jwasinger · Pull Request #33930 · ethereum/go-ethereum

jwasinger · 2026-03-02T23:27:04Z

Contains changes required for devnet 3. The BAL changes are in a branch here and build on several open PRs:

Other EIPs in devnet 3 with open PRs have been squashed into single commits and included on this branch:

EIPs missing from this branch:

EIP-8159: eth/71 - Block Access List Exchange (no implementation of it yet)

There's some new failing spec tests introduced in the 7928 changes. I am looking into them.

jwasinger · 2026-03-03T20:51:01Z

There's currently a lot of tests failing. Likely, some the failures are related to 8037, but I have yet to deep dive into them.

eth70 is ready to be merged :)

jwasinger · 2026-03-05T01:45:06Z

I rebased this because 7778 was merged. I also merged the eth 70 changes in here.

@MariusVanDerWijden I stripped the outdated 8037 changes from this branch.

If we are post-amsterdam, we need to exclude this from the regular gas. I am attempting to integrate #33648 in to this branch, which should make this change.

+			// When the calldata floor exceeds actual gas used, any
+			// remaining state gas must also be consumed
+			targetRemaining := (st.initialGas.RegularGas + st.initialGas.StateGas) - floorDataGas


can we get into a situation where targetRemaining > params.MaxTxGasLimit? If the tx gas limit is high, and the gas used low, the state gas might be vastly larger than floorDataGas.

CopyHeader copies all pointer-typed header fields (WithdrawalsHash, RequestsHash, SlotNumber, etc.) but was missing the deep copy for BlockAccessListHash added by EIP-7928. This caused the BAL hash to be silently shared between the original and the copy, leading to potential data races and incorrect nil-checks on copied headers.

Adds support for returning `blockAccessListHash` in the RPC block header response. This change includes `blockAccessListHash` in `RPCMarshalHeader` when `head.BlockAccessListHash` is not nil, aligning the RPC output with the Header struct which already contains this field.

* add method on StateReaderTracker to clear the accumulated reads * don't factor the BAL size into the payload size during construction in the miner * simplify miner code for constructing payloads-with-BALs via the use of aformentioned StateReaderTracker clear method * clean up the configuration of the BAL execution mode based on the preset flag specified

## Summary - The BAL refactoring in 5808d21 removed the line `env.header.GasUsed = env.gasPool.Used()` from `applyTransaction()`, causing all geth-proposed blocks to have `GasUsed=0` in the header - Every other client rejects these blocks during validation, so geth can never successfully propose on the network - Restores the single line that was present in upstream master ## Test plan - [x] Verified line exists in upstream/master at miner/worker.go:409 - [x] Confirmed all 34 geth-proposed blocks on a 4-client devnet had `GasUsed=0` via `debug_getBadBlocks` on besu - [ ] Build local image and verify geth proposals are accepted in a multi-client Kurtosis network

… made some changes to the --bal.executionmode flag

Rename `balHash` to `blockAccessListHash` in json encoding of block header. Fix miner panic when attempting to create pre-amsterdam blocks.

@MariusVanDerWijden I pushed a fix to an issue found by @qu0b . PTAL at 566992d and if it looks okay to you, we can add it to the 8037 branch.

Oops. Those fixes broke some tests. Reverted them until I can get them working

…with access lists Co-authored-by: spencer <spencer.tb@ethereum.org>

To check whether a transaction can be applied, we validate that `blockGasLimit > txGasLimit + (cumulativeRegularGasUsed + cumulativeStateGasUsed)`. However, the check should only be applied to the bottleneck resource, i.e. `blockGasLimit > max(txRegularGasUsed+cumulativeRegularGasUsed, txStateGasUsed+ cumulativeStateGasUsed)`. The changes here break multiple tests. I am trying to determine why. --------- Co-authored-by: qu0b <stefan@starflinger.eu>

…mapper

The BAL reader tracker captures access list reads at the reader level. When statedb has an account cached the BAL tracker is not informed of the access. This is ok during the lifetime of a transaction because you only need to record the access the first time. It is also ok during the lifetime of a block because BAL reads are block-level (same as statedb caches). Where I think the issue can rise is in the miner. Namely when building a block, if the miner picks up a tx which fails, it drops it and picks up another tx to include. There might be some edge case here where the failed tx which is not included poisons the cache and a future block which is included omits an account because it wasn't aware of the access.

Fixes the collision bugs and create gas ordering

 func (ch codeChange) revert(s *StateDB) {
-	s.getStateObject(ch.account).setCode(crypto.Keccak256Hash(ch.prevCode), ch.prevCode)
+	s.getStateObject(ch.account).SetCode(crypto.Keccak256Hash(ch.prevCode), ch.prevCode)


Appears to be a bug. SetCode will add a code change to the journal, which is not what we want here.

Wire up slotnum for `testing_buildBlockV1` for `bal-devnet-3` branch We are experimenting testing block building through hive via EELS (PR [here](ethereum/execution-specs#2679)). This is the only change needed to test against `bal-devnet-3` - missing slotnum.

…s, surface more metrics including prefetcher time (#34892) Adapts some of the changes from #34861 . Some other metrics which are recorded manually during execution in that PR, but can be deduced from the BAL are TBD. I've added two bal feature flags: * `--bal.prefetchworkers <uint>`: this tunes the number of concurrent go-routines that will be used to perform state fetching tasks by the BAL prefetcher. Default is `runtime.NumCPUs`, the current behavior in `bal-devnet-3`. * `--bal.blockingprefetch`: If set, state prefetching will block the execution of transactions and state root update. --------- Co-authored-by: CPerezz <cperezz19@pm.me>

…plumbing that gets the values to the blockchain config when instantiating for main command

A first attempt to get the entire slow_blocks to be BAL&parallel-exec-aware. - Sequential-path output is unchanged; the `bal` JSON field is `omitempty`. - All new types are pure-data snapshots (value receivers, no shared mutation), so they're safe to copy across goroutine boundaries in the parallel pipeline. --------- Co-authored-by: Jared Wasinger <j-wasinger@hotmail.com>
