For PeerDAS, we need to compute cell proofs. Both ckzg and gokzg support
computing these cell proofs.
This PR does the following:
- Update the go-kzg library from "github.com/crate-crypto/go-kzg-4844"
to "github.com/crate-crypto/go-eth-kzg" which will be the new upstream
for go-kzg moving forward
- Update ckzg from v1.0.0 to v2.0.1 and switch to /v2
- Updates the trusted setup to contain the g1 points both in lagrange
and monomial form
- Expose `ComputeCells` to compute the cell proofs
This PR adds a new `--beacon.checkpoint.file` config flag to geth and
blsync which specifies a checkpoint import/export file. If a file with
an existing checkpoint is specified, it is used for initialization
instead of the hardcoded one (except when `--beacon.checkpoint` is also
specified simultaneously). Whenever the client encounters a new valid
finality update with a suitable finalized beacon block root at an epoch
boundary, it saves the block root in hex format to the checkpoint file.
When I'm running `geth import --metrics`, the metrics is different to
normal `geth --metrics`, so the grafana dashboard needs to be updated,
eg: `eth_db_chaindata_disk_read` vs `disk_read`.
So I think we should always set the name to `eth/db/chaindata` for more
convenient.

this adds 2 features to improve `geth --dev` experience.
1. we don't need to use `dev_SetFeeRecipient` to set initial coinbase
address. it was a pain.
2. we don't need to unlock keystore if we don't use it. we had it
because of clique.
Here I am adding a config option and geth flag (`--history.chain`) for
configuring history pruning. There are two options available:
- `--history.chain all` is the default and will keep all history like
before.
- `--history.chain postmerge` will configure the history cutoff point to
the merge block.
The option doesn't actually do anything right now, but we need it as a
precursor for other history pruning changes.
This implements a basic mechanism to query the node's external IP using
a STUN server. There is a built-in list of public STUN servers for convenience.
The new detection mechanism must be selected explicitly using `--nat=stun`
and is not enabled by default in Geth.
Fixes#30881

This PR modifies how the metrics library handles `Enabled`: previously,
the package `init` decided whether to serve real metrics or just
dummy-types.
This has several drawbacks:
- During pkg init, we need to determine whether metrics are enabled or
not. So we first hacked in a check if certain geth-specific
commandline-flags were enabled. Then we added a similar check for
geth-env-vars. Then we almost added a very elaborate check for
toml-config-file, plus toml parsing.
- Using "real" types and dummy types interchangeably means that
everything is hidden behind interfaces. This has a performance penalty,
and also it just adds a lot of code.
This PR removes the interface stuff, uses concrete types, and allows for
the setting of Enabled to happen later. It is still assumed that
`metrics.Enable()` is invoked early on.
The somewhat 'heavy' operations, such as ticking meters and exp-decay,
now checks the enable-flag to prevent resource leak.
The change may be large, but it's mostly pretty trivial, and from the
last time I gutted the metrics, I ensured that we have fairly good test
coverage.

Lots of packages depend on eth/downloader just for the SyncMode type.
Since we have a dedicated package for eth protocol configuration, it
makes more sense to define SyncMode there, turning eth/downloader into
more of a leaf package.
This is one further step towards removing account management from
`geth`. This PR deprecates the flag `unlock`, and makes the flag moot:
unlock via geth is no longer possible.
This PR moves chain config related code (config file processing, fork
logic, network defaults) from `beacon/types` and `beacon/blsync` into
`beacon/params` while the command line flag logic of the chain config is
moved into `cmd/utils`, thereby removing the cli dependencies from
package `beacon` and its sub-packages.
This PR is a first step towards removing account management from geth,
and contains a lot of the user-facing changes.
With this PR, the `personal` namespace disappears. **Note**: `personal`
namespace has been deprecated for quite some time (since
https://github.com/ethereum/go-ethereum/pull/26390 1 year and 8 months
ago), and users who have wanted to use it has been forced to used the
flag `--rpc.enabledeprecatedpersonal`. So I think it's fairly
non-controversial to drop it at this point.
Specifically, this means:
- Account/wallet listing
-`personal.getListAccounts`
-`personal.listAccounts`
-`personal.getListWallets`
-`personal.listWallets`
- Lock/unlock
-`personal.lockAccount`
-`personal.openWallet`
-`personal.unlockAccount`
- Sign ops
-`personal.sign`
-`personal.sendTransaction`
-`personal.signTransaction`
- Imports / inits
-`personal.deriveAccount`
-`personal.importRawKey`
-`personal.initializeWallet`
-`personal.newAccount`
-`personal.unpair`
- Other:
-`personal.ecRecover`
The underlying keystores and account managent code is still in place,
which means that `geth --dev` still works as expected, so that e.g. the
example below still works:
```
> eth.sendTransaction({data:"0x6060", value: 1, from:eth.accounts[0]})
```
Also, `ethkey` and `clef` are untouched.
With the removal of `personal`, as far as I know we have no more API
methods which contain credentials, and if we want to implement
logging-capabilities of RPC ingress payload, it would be possible after
this.

Currently we have a custom TextMarshalerFlag. It's a nice idea, allowing
anything implementing text marshaller to be used as a flag. That said,
we only ever used it in one place because it's not that obvious how to
use and it needs some boilerplate on the type itself too, apart of the
heavy boilerplate got the custom flag.
All in all there's no *need* to drop this feature just now, but while
porting the cmds over to cli @v3, all other custom flags worker
perfectly, whereas this one started crashing deep inside the cli
package. The flag handling in v3 got rebuild on generics and there are a
number of new methods needed; and my guess is that maybe one of them
doesn't work like this flag currently is designed too.
We could definitely try and redesign this flag for cli v3... but all
that effort and boilerplate just to use it for 1 flag in 1 location,
seems not worth it. So for now I'm suggesting removing it and maybe
reconsider a similar feature in cli v3 with however it will work.
rebased https://github.com/ethereum/go-ethereum/pull/29766 . The
downstream branch appears to have been deleted and I don't have perms to
push to that fork.
`TerminalTotalDifficultyPassed` is removed. `TerminalTotalDifficulty`
must now be non-nil, and it is expected that networks are already
merged: we can only import PoW/Clique chains, not produce blocks on
them.

Breaking changes:
- The ChainConfig was exposed to tracers via VMContext passed in
`OnTxStart`. This is unnecessary specially looking through the lens of
live tracers as chain config remains the same throughout the lifetime of
the program. It was there so that native API-invoked tracers could
access it. So instead we moved it to the constructor of API tracers.
Non-breaking:
- Change the default config of the tracers to be `{}` instead of nil.
This way an extra nil check can be avoided.
Refactoring:
- Rename `supply` struct to `supplyTracer`.
- Un-export some hook definitions.
This PR integrates witness-enabled block production, witness-creating
payload execution and stateless cross-validation into the `engine` API.
The purpose of the PR is to enable the following use-cases (for API
details, please see next section):
- Cross validating locally created blocks:
- Call `forkchoiceUpdatedWithWitness` instead of `forkchoiceUpdated` to
trigger witness creation too.
- Call `getPayload` as before to retrieve the new block and also the
above created witness.
- Call `executeStatelessPayload` against another client to
cross-validate the block.
- Cross validating locally processed blocks:
- Call `newPayloadWithWitness` instead of `newPayload` to trigger
witness creation too.
- Call `executeStatelessPayload` against another client to
cross-validate the block.
- Block production for stateless clients (local or MEV builders):
- Call `forkchoiceUpdatedWithWitness` instead of `forkchoiceUpdated` to
trigger witness creation too.
- Call `getPayload` as before to retrieve the new block and also the
above created witness.
- Propagate witnesses across the consensus libp2p network for stateless
Ethereum.
- Stateless validator validation:
- Call `executeStatelessPayload` with the propagated witness to
statelessly validate the block.
*Note, the various `WithWitness` methods could also *just be* an
additional boolean flag on the base methods, but this PR wanted to keep
the methods separate until a final consensus is reached on how to
integrate in production.*
---
The following `engine` API types are introduced:
```go
// StatelessPayloadStatusV1 is the result of a stateless payload execution.
type StatelessPayloadStatusV1 struct {
Status string `json:"status"`
StateRoot common.Hash `json:"stateRoot"`
ReceiptsRoot common.Hash `json:"receiptsRoot"`
ValidationError *string `json:"validationError"`
}
```
- Add `forkchoiceUpdatedWithWitnessV1,2,3` with same params and returns
as `forkchoiceUpdatedV1,2,3`, but triggering a stateless witness
building if block production is requested.
- Extend `getPayloadV2,3` to return `executionPayloadEnvelope` with an
additional `witness` field of type `bytes` iff created via
`forkchoiceUpdatedWithWitnessV2,3`.
- Add `newPayloadWithWitnessV1,2,3,4` with same params and returns as
`newPayloadV1,2,3,4`, but triggering a stateless witness creation during
payload execution to allow cross validating it.
- Extend `payloadStatusV1` with a `witness` field of type `bytes` if
returned by `newPayloadWithWitnessV1,2,3,4`.
- Add `executeStatelessPayloadV1,2,3,4` with same base params as
`newPayloadV1,2,3,4` and one more additional param (`witness`) of type
`bytes`. The method returns `statelessPayloadStatusV1`, which mirrors
`payloadStatusV1` but replaces `latestValidHash` with `stateRoot` and
`receiptRoot`.
This PR changes how sidechains are handled.
Before the merge, it was possible to import a chain with lower td and not set it as canonical. After the merge, we expect every chain that we get via InsertChain to be canonical. Non-canonical blocks can still be inserted
with InsertBlockWIthoutSetHead.
If during the InsertChain, the existing chain is not canonical anymore, we mark it as a sidechain and send the SideChainEvents normally.
Currently, we have 3 flags to configure blob pool. However, we don't
read these flags and set the blob pool configuration in eth config
accordingly. This commit adds a function to check if these flags are
provided and set blob pool configuration based on them.
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.
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.

Here we add a beacon chain light client for use by geth.
Geth can now be configured to run against a beacon chain API endpoint,
without pointing a CL to it. To set this up, use the `--beacon.api` flag. Information
provided by the beacon chain is verified, i.e. geth does not blindly trust the beacon
API endpoint in this mode. The root of trust are the beacon chain 'sync committees'.
The configured beacon API endpoint must provide light client data. At this time, only
Lodestar and Nimbus provide the necessary APIs.
There is also a standalone tool, cmd/blsync, which uses the beacon chain light client
to drive any EL implementation via its engine API.

This PR replaces Geth's logger package (a fork of [log15](https://github.com/inconshreveable/log15)) with an implementation using slog, a logging library included as part of the Go standard library as of Go1.21.
Main changes are as follows:
* removes any log handlers that were unused in the Geth codebase.
* Json, logfmt, and terminal formatters are now slog handlers.
* Verbosity level constants are changed to match slog constant values. Internal translation is done to make this opaque to the user and backwards compatible with existing `--verbosity` and `--vmodule` options.
* `--log.backtraceat` and `--log.debug` are removed.
The external-facing API is largely the same as the existing Geth logger. Logger method signatures remain unchanged.
A small semantic difference is that a `Handler` can only be set once per `Logger` and not changed dynamically. This just means that a new logger must be instantiated every time the handler of the root logger is changed.
----
For users of the `go-ethereum/log` module. If you were using this module for your own project, you will need to change the initialization. If you previously did
```golang
log.Root().SetHandler(log.LvlFilterHandler(log.LvlInfo, log.StreamHandler(os.Stderr, log.TerminalFormat(true))))
```
You now instead need to do
```golang
log.SetDefault(log.NewLogger(log.NewTerminalHandlerWithLevel(os.Stderr, log.LevelInfo, true)))
```
