The first validator in snap.Recents is shifted out and allowed to seal the block
already. However, when determining if we should slash the validator in Finalize
and FinalizeAndAssemble, we mark that first validator as unable to seal block
and don't slash this validator. This commit fixes that bug and creates a
separate helper function to check if the validator recently signed a block for
consistency in all places the check happens.
The EIP150Hash was an idea where, after the fork, we hardcoded the forked hash as an extra defensive mechanism. It wasn't really used, since forks weren't contentious and for all the various testnets and private networks it's been a hassle to have around.
This change removes that config field.

Makes clear the distinction between Finalize and FinalizedAndAssemble:
- In Finalize function, a series of state operations are applied according to consensus rules. The statedb is mutated and the root hash can be checked and compared afterwards.
This function should be used in block processing(receive afrom network and apply it locally) but not block generation.
- In FinalizeAndAssemble function, after applying state mutations, the block is also to be assembled with the latest
state root computed, updating the header.
This function should be used in block generation only.
The EmptyRootHash and EmptyCodeHash are defined everywhere in the codebase, this PR replaces all of them with unified one defined in core/types package, and also defines constants for TxRoot, WithdrawalsRoot and UncleRoot
This PR is a (superior) alternative to https://github.com/ethereum/go-ethereum/pull/26708, it handles deprecation, primarily two specific cases.
`rand.Seed` is typically used in two ways
- `rand.Seed(time.Now().UnixNano())` -- we seed it, just to be sure to get some random, and not always get the same thing on every run. This is not needed, with global seeding, so those are just removed.
- `rand.Seed(1)` this is typically done to ensure we have a stable test. If we rely on this, we need to fix up the tests to use a deterministic prng-source. A few occurrences like this has been replaced with a proper custom source.
`rand.Read` has been replaced by `crypto/rand`.`Read` in this PR.

This PR builds on #26299, but also updates the tests to the most recent version, which includes tests regarding TheMerge.
This change adds checks to the beacon consensus engine, making it more strict in validating the pre- and post-headers, and not relying on the caller to have already correctly sanitized the headers/blocks.
When new block is imported, there is no need to commit the current
work, even the new imported block is offturn and itself is inturn.
That is because when offturn block is received, the inturn block is
already later to broadcast block, deliver the later block will cause
many reorg, which is not reasonable.
And also make sure all useless work can be discarded, to avoid goroutine leak.
Currently, validator only try once to get transactions from TxPool to produce the block.
However, new transactions could arrive while the validator is committing transaction.
Validator should be allowed to add these new arrived transactions as long as
Header.Timestamp is not reached
This commit will:
** commitTransactions return with error code
** drop current mining block on new block imported
** try fillTransactions several times for the best
not use append mode to follow the GasPrice rule.
** check if there is enough time for another fillTransactions.
Right now, DelayLeftOver is used to reserve time for block finalize, not block
broadcast. And the code does not work as expected.
The general block generation could be described as:
|- fillTransactions -|- finalize a block -|- wait until the period(3s) reached -|- broadcast -|
This PR changes geth to read the eip1559 params from the chain config instead of the globals.
This way the parameters may be changed by forking the chain config code, without creating a large diff throughout the past and future usages of the parameters.
