Way back we've added `common.math.BigMin` and `common.math.BigMax`.
These were kind of cute helpers, but unfortunate ones, because package
all over out codebase added dependencies to this package just to avoid
having to write out 3 lines of code.
Because of this, we've also started having package name clashes with the
stdlib `math`, which got solves even more badly by moving some helpers
over ***from*** the stdlib into our custom lib (e.g. MaxUint64). The
latter ones were nuked out in a previous PR and this PR nukes out BigMin
and BigMax, inlining them at all call sites.
As we're transitioning to uint256, if need be, we can add a min and max
to that.
This is a successor PR to #25743. This PR is based on a new iteration of
the spec: https://github.com/ethereum/execution-apis/pull/484.
`eth_multicall` takes in a list of blocks, each optionally overriding
fields like number, timestamp, etc. of a base block. Each block can
include calls. At each block users can override the state. There are
extra features, such as:
- Include ether transfers as part of the logs
- Overriding precompile codes with evm bytecode
- Redirecting accounts to another address
## Breaking changes
This PR includes the following breaking changes:
- Block override fields of eth_call and debug_traceCall have had the
following fields renamed
- `coinbase` -> `feeRecipient`
- `random` -> `prevRandao`
- `baseFee` -> `baseFeePerGas`

This PR implements changes related to
[EIP-6800](https://eips.ethereum.org/EIPS/eip-6800) and
[EIP-4762](https://eips.ethereum.org/EIPS/eip-4762) spec updates.
A TL;DR of the changes is that `Version`, `Balance`, `Nonce` and
`CodeSize` are encoded in a single leaf named `BasicData`. For more
details, see the [_Header Values_ table in
EIP-6800](https://eips.ethereum.org/EIPS/eip-6800#header-values).
The motivation for this was simplifying access event patterns, reducing
code complexity, and, as a side effect, saving gas since fewer leaf
nodes must be accessed.

It's a bit confusing to add msg.value into the balanceCheck within the conditional.
No impact on block validation since GasFeeCap is always set when processing transactions.
Here we add a Go API for running tracing plugins within the main block import process.
As an advanced user of geth, you can now create a Go file in eth/tracers/live/, and within
that file register your custom tracer implementation. Then recompile geth and select your tracer
on the command line. Hooks defined in the tracer will run whenever a block is processed.
The hook system is defined in package core/tracing. It uses a struct with callbacks, instead of
requiring an interface, for several reasons:
- We plan to keep this API stable long-term. The core/tracing hook API does not depend on
on deep geth internals.
- There are a lot of hooks, and tracers will only need some of them. Using a struct allows you
to implement only the hooks you want to actually use.
All existing tracers in eth/tracers/native have been rewritten to use the new hook system.
This change breaks compatibility with the vm.EVMLogger interface that we used to have.
If you are a user of vm.EVMLogger, please migrate to core/tracing, and sorry for breaking
your stuff. But we just couldn't have both the old and new tracing APIs coexist in the EVM.

This change makes use of uin256 to represent balance in state. It touches primarily upon statedb, stateobject and state processing, trying to avoid changes in transaction pools, core types, rpc and tracers.
The code to compute a versioned hash was duplicated a couple times, and also had a small
issue: if we ever change params.BlobTxHashVersion, it will most likely also cause changes
to the actual hash computation. So it's a bit useless to have this constant in params.
EIP-4844 adds a new transaction type for blobs. Users can submit such transactions via `eth_sendRawTransaction`. In this PR we refrain from adding support to `eth_sendTransaction` and in fact it will fail if the user passes in a blob hash.
However since the chain can handle such transactions it makes sense to allow simulating them. E.g. an L2 operator should be able to simulate submitting a rollup blob and updating the L2 state. Most methods that take in a transaction object should recognize blobs. The change boils down to adding `blobVersionedHashes` and `maxFeePerBlobGas` to `TransactionArgs`. In summary:
- `eth_sendTransaction`: will fail for blob txes
- `eth_signTransaction`: will fail for blob txes
The methods that sign txes does not, as of this PR, add support the for new EIP-4844 transaction types. Resuming the summary:
- `eth_sendRawTransaction`: can send blob txes
- `eth_fillTransaction`: will fill in a blob tx. Note: here we simply fill in normal transaction fields + possibly `maxFeePerBlobGas` when blobs are present. One can imagine a more elaborate set-up where users can submit blobs themselves and we fill in proofs and commitments and such. Left for future PRs if desired.
- `eth_call`: can simulate blob messages
- `eth_estimateGas`: blobs have no effect here. They have a separate unit of gas which is not tunable in the transaction.

This updates the reference tests to the latest version and also adds logic
to process EIP-4844 blob transactions into the state transition. We are now
passing most Cancun fork tests.
