The fetcher should not fetch transactions that are already on chain.
Until now we were only checking in the txpool, but that does not have
the old transaction. This was leading to extra fetches of transactions
that were announced by a peer but are already on chain.
Here we extend the check to the chain as well.
The upstream libray has removed the assembly-based implementation of
keccak. We need to maintain our own library to avoid a peformance
regression.

This PR fixes an issue where `evm statetest` would not verify the
post-state root hash if the test case expected an exception (e.g.
invalid transaction).
The fix involves:
1. Modifying `tests/state_test_util.go` in the `Run` method.
2. When an expected error occurs (`err != nil`), we now check if
`post.Root` is defined.
3. If defined, we recalculate the intermediate root from the current
state (which is reverted to the pre-transaction snapshot upon error).
4. We use `GetChainConfig` and `IsEIP158` to ensure the correct state
clearing rules are applied when calculating the root, avoiding
regressions on forks that require EIP-158 state clearing.
5. If the calculated root mismatches the expected root, the test now
fails.
This ensures that state tests are strictly verified against their
expected post-state, even for failure scenarios.
Fixes issue #33527

### Description
Add a new `OnStateUpdate` hook which gets invoked after state is
committed.
### Rationale
For our particular use case, we need to obtain the state size metrics at
every single block when fuly syncing from genesis. With the current
state sizer, whenever the node is stopped, the background process must
be freshly initialized. During this re-initialization, it can skip some
blocks while the node continues executing blocks, causing gaps in the
recorded metrics.
Using this state update hook allows us to customize our own data
persistence logic, and we would never skip blocks upon node restart.

This PR fixes the bug reported in #33365.
The impact of the bug is not catastrophic. After a transaction is
ultimately fetched, validation and propagation will be performed based
on the fetched body, and any response with a mismatched type is treated
as a protocol violation. An attacker could only waste the limited
portion of victim’s bandwidth at most.
However, the reasons for submitting this PR are as follows
1. Fetching a transaction announced with an arbitrary type is a weird
behavior.
2. It aligns with efforts such as EIP-8077 and #33119 to make the
fetcher smarter and reduce bandwidth waste.
Regarding the `FilterType` function, it could potentially be implemented
by modifying the Filter function's parameter itself, but I wasn’t sure
whether changing that function is acceptable, so I left it as is.
Enable blocktest to read filenames from stdin when no path argument is
provided, matching the existing statetest behavior. This allows
efficient batch processing of blockchain tests.
Usage:
- Single file: evm blocktest <path>
- Batch mode: find tests/ -name "*.json" | evm blocktest

This is broken off of #31730 to only focus on testing networks that
start with verkle at genesis.
The PR has seen a lot of work since its creation, and it now targets
creating and re-executing tests for a binary tree testnet without the
transition (so it starts at genesis). The transition tree has been moved
to its own package. It also replaces verkle with the binary tree for
this specific application.

This pr implements https://github.com/ethereum/go-ethereum/issues/32733
to make StateProcessor more customisable.
## Compatibility notes
This introduces a breaking change to users using geth EVM as a library.
The `NewStateProcessor` function now takes one parameter which has the
chainConfig embedded instead of 2 parameters.
https://github.com/ethereum/execution-spec-tests/releases/tag/v5.0.0
As of this release, execution-spec-tests also contains all state tests
that were previously in ethereum/tests. We can probably remove the tests
submodule now. However, this would mean we are missing the pre-cancun
tests. Still need to figure out how to resolve this.

In this pull request, the original `CacheConfig` has been renamed to `BlockChainConfig`.
Over time, more fields have been added to `CacheConfig` to support
blockchain configuration. Such as `ChainHistoryMode`, which clearly extends
beyond just caching concerns.
Additionally, adding new parameters to the blockchain constructor has
become increasingly complicated, since it’s initialized across multiple
places in the codebase. A natural solution is to consolidate these arguments
into a dedicated configuration struct.
As a result, the existing `CacheConfig` has been redefined as `BlockChainConfig`.
Some parameters, such as `VmConfig`, `TxLookupLimit`, and `ChainOverrides`
have been moved into `BlockChainConfig`. Besides, a few fields in `BlockChainConfig`
were renamed, specifically:
- `TrieCleanNoPrefetch` -> `NoPrefetch`
- `TrieDirtyDisabled` -> `ArchiveMode`
Notably, this change won't affect the command line flags or the toml
configuration file. It's just an internal refactoring and fully backward-compatible.

In this pull request, snapshot generation in pathdb has been ported from
the legacy state snapshot implementation. Additionally, when running in
path mode, legacy state snapshot data is now managed by the pathdb
based snapshot logic.
Note: Existing snapshot data will be re-generated, regardless of whether
it was previously fully constructed.
When we instantiate a sub-logger via
`go-ethereum/internal/testlog/logger.With`, we copy the reference to the
`bufHandler` from the parent logger. However, internally,
`go-ethereum/internal/testlog/logger.With` calls `log/slog/Logger.With`
which creates a new handler instance (via
`internal/bufHandler.WithAttrs`).
This PR modifies sub-logger instantiation to use the newly-instantiated
handler, instead of copying the reference from the parent instance. The
type cast from `slog.Handler` to `*bufHandler` in
`internal/testlog/Logger.With` is safe here because a
`internal/testlog/Logger` can only be instantiated with a `*bufHandler`
as the underlying handler type.
Note, that I've also removed a pre-existing method that broke the above
assumption. However, this method is not used in our codebase.
I'm not sure if the assumption holds for forks of geth (e.g. optimism
has modified the testlogger somewhat allowing test loggers to accept
arbitrary handler types), but it seems okay to break API compatibility
given that this is in the `internal` package.

The TestTransactionForgotten test was flaky due to real time
dependencies. This PR:
- Replaces real time with mock clock for deterministic timing control
- Adds precise state checks at timeout boundaries
- Verifies underpriced cache states and cleanup
- Improves test reliability by controlling transaction timestamps
- Adds checks for transaction re-enqueueing behavior
The changes ensure consistent test behavior without timing-related
flakiness.

This PR does a few things including:
- Remove `ContractRef` interface
- Remove `vm.AccountRef` which implements `ContractRef` interface
- Maintain the `jumpDests` struct in EVM for sharing between call frames
- Simplify the delegateCall context initialization
Here we add some more changes for live tracing API v1.1:
- Hook `OnSystemCallStartV2` was introduced with `VMContext` as parameter.
- Hook `OnBlockHashRead` was introduced.
- `GetCodeHash` was added to the state interface
- The new `WrapWithJournal` construction helps with tracking EVM reverts in the tracer.

Fixes a typo in the error message within the `fuzzCrossG2Add`
function. The panic message incorrectly references "G1 point addition
mismatch" when it should be "G2 point addition mismatch," as the
function deals with G2 points.
This doesn't affect functionality but could cause confusion during
debugging. I've updated the message to reflect the correct curve.
The total difficulty is the sum of all block difficulties from genesis
to a certain block. This value was used in PoW for deciding which chain
is heavier, and thus which chain to select. Since PoS has a different
fork selection algorithm, all blocks since the merge have a difficulty
of 0, and all total difficulties are the same for the past 2 years.
Whilst the TDs are mostly useless nowadays, there was never really a
reason to mess around removing them since they are so tiny. This
reasoning changes when we go down the path of pruned chain history. In
order to reconstruct any TD, we **must** retrieve all the headers from
chain head to genesis and then iterate all the difficulties to compute
the TD.
In a world where we completely prune past chain segments (bodies,
receipts, headers), it is not possible to reconstruct the TD at all. In
a world where we still keep chain headers and prune only the rest,
reconstructing it possible as long as we process (or download) the chain
forward from genesis, but trying to snap sync the head first and
backfill later hits the same issue, the TD becomes impossible to
calculate until genesis is backfilled.
All in all, the TD is a messy out-of-state, out-of-consensus computed
field that is overall useless nowadays, but code relying on it forces
the client into certain modes of operation and prevents other modes or
other optimizations. This PR completely nukes out the TD from the node.
It doesn't compute it, it doesn't operate on it, it's as if it didn't
even exist.
Caveats:
- Whenever we have APIs that return TD (devp2p handshake, tracer, etc.)
we return a TD of 0.
- For era files, we recompute the TD during export time (fairly quick)
to retain the format content.
- It is not possible to "verify" the merge point (i.e. with TD gone, TTD
is useless). Since we're not verifying PoW any more, just blindly trust
it, not verifying but blindly trusting the many year old merge point
seems just the same trust model.
- Our tests still need to be able to generate pre and post merge blocks,
so they need a new way to split the merge without TTD. The PR introduces
a settable ttdBlock field on the consensus object which is used by tests
as the block where originally the TTD happened. This is not needed for
live nodes, we never want to generate old blocks.
- One merge transition consensus test was disabled. With a
non-operational TD, testing how the client reacts to TTD is useless, it
cannot react.
Questions:
- Should we also drop total terminal difficulty from the genesis json?
It's a number we cannot react on any more, so maybe it would be cleaner
to get rid of even more concepts.

This pull request delivers the new version of the state history, where
the raw storage key is used instead of the hash.
Before the cancun fork, it's supported by protocol to destruct a
specific account and therefore, all the storage slot owned by it should
be wiped in the same transition.
Technically, storage wiping should be performed through storage
iteration, and only the storage key hash will be available for traversal
if the state snapshot is not available. Therefore, the storage key hash
is chosen as the identifier in the old version state history.
Fortunately, account self-destruction has been deprecated by the
protocol since the Cancun fork, and there are no empty accounts eligible
for deletion under EIP-158. Therefore, we can conclude that no storage
wiping should occur after the Cancun fork. In this case, it makes no
sense to keep using hash.
Besides, another big reason for making this change is the current format
state history is unusable if verkle is activated. Verkle tree has a
different key derivation scheme (merkle uses keccak256), the preimage of
key hash must be provided in order to make verkle rollback functional.
This pull request is a prerequisite for landing verkle.
Additionally, the raw storage key is more human-friendly for those who
want to manually check the history, even though Solidity already
performs some hashing to derive the storage location.
---
This pull request doesn't bump the database version, as I believe the
database should still be compatible if users degrade from the new geth
version to old one, the only side effect is the persistent new version
state history will be unusable.

We still need to decide how to handle non-specfic `chainId` in the JSON
encoding of authorizations. With `chainId` being a uint64, the previous
implementation just used value zero. However, it might actually be more
correct to use the value `null` for this case.
Here I am proposing two small changes to the exported API for EIP-7702:
(1) `Authorization` has a very generic name, but it is in fact only used
for one niche use case: authorizing code in a `SetCodeTx`. So I propose
calling it `SetCodeAuthorization` instead. The signing function is
renamed to `SignSetCode` instead of `SignAuth`.
(2) The signing function for authorizations should take key as the first
parameter, and the authorization second. The key will almost always be
in a variable, while the authorization can be given as a literal.
This PR implements EIP-7702: "Set EOA account code".
Specification: https://eips.ethereum.org/EIPS/eip-7702
> Add a new transaction type that adds a list of `[chain_id, address,
nonce, y_parity, r, s]` authorization tuples. For each tuple, write a
delegation designator `(0xef0100 ++ address)` to the signing account’s
code. All code reading operations must load the code pointed to by the
designator.

This pull request refactors the EVM constructor by removing the
TxContext parameter.
The EVM object is frequently overused. Ideally, only a single EVM
instance should be created and reused throughout the entire state
transition of a block, with the transaction context switched as needed
by calling evm.SetTxContext.
Unfortunately, in some parts of the code, the EVM object is repeatedly
created, resulting in unnecessary complexity. This pull request is the
first step towards gradually improving and simplifying this setup.

The [kilic](https://github.com/kilic/bls12-381) bls12381 implementation
has been archived. It shouldn't be necessary to include it as a fuzzing
target any longer.
This also adds fuzzers for G1/G2 mul that use inputs that are guaranteed
to be valid. Previously, we just did random input fuzzing for these
precompiles.
When `evm statetest --bench` is specified, benchmark the execution
similarly to `evm run`.
Also adds the ability to filter tests by name, index and fork.
