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`

In few tests the returned error from `SendTransaction` is not being
checked. This PR checks the returned err in tests.
Returning errors also revealed tx in `TestCommitReturnValue` is not
actually being sent, and returns err ` only replay-protected (EIP-155)
transactions allowed over RPC`. Fixed the transaction by using the
`testTx` function.
Some chains’ network IDs use hexadecimal such as Optimism ("0xa" instead
of "10"), so when converting the string to big.Int, we cannot specify
base 10; otherwise, it will encounter errors with hexadecimal network
IDs.
* all: refactor so NewBlock(..) and WithBody(..) take a types.Body
* core: fixup comments, remove txs != receipts panic
* core/types: add empty withdrawls to body if len == 0
This change removes support for subscribing to pending logs.
"Pending logs" were always an odd feature, because it can never be fully reliable. When support for it was added many years ago, the intention was for this to be used by wallet apps to show the 'potential future token balance' of accounts, i.e. as a way of notifying the user of incoming transfers before they were mined. In order to generate the pending logs, the node must pick a subset of all public mempool transactions, execute them in the EVM, and then dispatch the resulting logs to API consumers.

* eth: get rid of miner.setEtherbase
* ethstats: remove miner and hashrate flags
* ethstats: remove miner and hashrate flags
* cmd: rename pendingBlockProducer to miner.pending.feeRecipient flag
* miner: use pendingFeeRecipient instead of etherbase
* miner: add mutex to protect the pending block
* miner: add mutex to protect the pending block
* eth: get rid of etherbase mentions
* miner: no need to lock the coinbase
* eth, miner: fix linter

* eth, miner: fix enforcing the minimum miner tip
* ethclient/simulated: fix failing test due the min tip change
* accounts/abi/bind: fix simulater gas tip issue
Given the discussions around deprecating pending (see #28623 or ethereum/execution-apis#495), we can move away from using the pending block internally, and use latest instead
* accounts, ethclient: minor tweaks on the new simulated backend
* ethclient/simulated: add an initial batch of gas options
* accounts, ethclient: remove mandatory gasLimit constructor param
* accounts, ethclient: minor option naming tweaks
This is a rewrite of the 'simulated backend', an implementation of the ethclient interfaces
which is backed by a simulated blockchain. It was getting annoying to maintain the old
version of the simulated backend feature because there was a lot of code duplication with
the main client.
The new version is built using parts that we already have: an in-memory geth node instance
running in developer mode provides the chain, while the Go API is provided by ethclient.
A backwards-compatibility wrapper is provided, but the simulated backend has also moved to
a more sensible import path: github.com/ethereum/go-ethereum/ethclient/simulated

* api/bind: Add CallOpts.BlockHash to allow calling contracts at a specific block hash.
* ethclient: Add BalanceAtHash, NonceAtHash and StorageAtHash functions
This change fixes#28355, where eth_getProof failed to return the correct codehash under certain conditions. This PR changes the logic to unconditionally look up the codehash, and also adds some more tests.
This changes the eth_getProof method implementation to re-encode the requested
storage keys, canonicalizing them in the response. For backwards-compatibility reasons,
go-ethereum accepts non-canonical hex keys. Accepting them is fine, but we should
not mirror invalid inputs into the output.
Closes#27306

ethclient accepts certain negative block number values as specifiers for the "pending",
"safe" and "finalized" block. In case of "pending", the value accepted by ethclient (-1)
did not match rpc.PendingBlockNumber (-2).
This wasn't really a problem, but other values accepted by ethclient did match the
definitions in package rpc, and it's weird to have this one special case where they don't.
To fix it, we decided to change the values of the constants rather than changing ethclient.
The constant values are not otherwise significant. This is a breaking API change, but we
believe not a dangerous one.

Adds an optional config parameter to eth_call which allows users to override block context fields (same functionality that was added to traceCall in #24871)

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 adds a way to subscribe to the _full_ pending transactions, as opposed to just being notified about hashes.
In use cases where client subscribes to newPendingTransactions and gets txhashes only to then request the actual transaction, the caller can now shortcut that flow and obtain the transactions directly.
