9deec69cc7 Do not verify block signature on block processing (#14820)
Verifying the block signature adds a batch and performs a full hash of
the block unnecessarily.

**What type of PR is this?**

Performance

**What does this PR do? Why is it needed?**

`PendingBalanceToWithdraw` was used to find the `bal` only to check
later if `bal` is greater than 0 or not. No need to calculate the full
balance and we could just check if `bal` is greater than 0 or not by
using an existing function `HasPendingBalanceToWithdraw`. So this should
help in reducing some unnecessary computation.

`HasPendingBalanceToWithdraw` returns immediately on first match of
non-zero instance, while `PendingBalanceToWithdraw` always iterates
through all entries to compute the sum.

8191bb5711 Construct data column sidecars from the execution layer in parallel and add metrics (#16115)
**What type of PR is this?**
Optimisation

**What does this PR do? Why is it needed?**
While constructing data column sidecars from the execution layer is very
cheap compared to reconstructing data column sidecars from data column
sidecars, it is still efficient to run this construction in parallel.

(**Reminder:** Using `getBlobsV2`, all the cell proofs are present, but
only 64 (out of 128) cells are present. Recomputing the missing cells is
cheap, while reconstruction the missing proofs is expensive.)

This PR:
- adds some metrics
- ensure the construction is done in parallel

The last commit transforms the bottom right histogram to summary, since
it makes no sense any more to have an histogram for values.

**What type of PR is this?**

**What does this PR do? Why is it needed?**

- Remove unnecessary `Copy()` call in `Eth1DataHasEnoughSupport`
- `data.Copy()` was called on every iteration of the vote counting loop,
even though `AreEth1DataEqual` only reads the data and never mutates it.
- Additionally, `Eth1DataVotes()` already returns copies of all votes,
so state is protected regardless.

Feature


**What does this PR do? Why is it needed?**

| Feature | Semi-Supernode | Supernode |
| ----------------------- | ------------------------- |
------------------------ |
| **Custody Groups** | 64 | 128 |
| **Data Columns** | 64 | 128 |
| **Storage** | ~50% | ~100% |
| **Blob Reconstruction** | Yes (via Reed-Solomon) | No reconstruction
needed |
| **Flag** | `--semi-supernode` | `--supernode` |
| **Can serve all blobs** | Yes (with reconstruction) | Yes (directly) |

**note** if your validator total effective balance results in more
custody than the semi-supernode it will override those those
requirements.

cgc=64 from @nalepae 
Pro:
- We are useful to the network
- Less disconnection likelihood
- Straight forward to implement

Con:
- We cannot revert to a full node
- We have to serve incoming RPC requests corresponding to 64 columns

26b276660f Avoid unnecessary calls to ExitInformation() (#15764)
* Avoid unnecessary calls to ExitInformation()

ExitInformation runs a loop over the whole validator set. This is needed
in case that there are slashings or exits to be processed in a block (we
could be caching or avoid this entirely post-Electra though). This PR
removes these calls on normal state transition to this function. h/t to
@terencechain for finding out this bug.

In addition, on processing withdrawal requests and registry updates, we
kept recomputing the exit information at the same time that the state is
updated and the function that updates the state already takes care of
tracking and updating the right exit information. So this PR removes the
calls to compute this exit information on a loop. Notice that this bug
has been present even before we had a function `ExitInformation()` so I
will document here to help the reviewer

Our previous behavior is to do this in a loop

```
st, err = validators.InitiateValidatorExit(ctx, st, vIdx, validators.ExitInformation(st))
```

This is a bit problematic since `ExitInformation` loops over the whole validator set to compute the exit information (and the total active balance) and then the function `InitiateValidatorExit` actually recomputes the total active balance looping again over the whole validator set and overwriting the pointer returned by `ExitInformation`.

On the other hand, the funciton `InitiateValidatorExit` does mutate the state `st` itself. So each call to `ExitInformation(st)` may actually return a different pointer.

The function ExitInformation computes as follows

```
	err := s.ReadFromEveryValidator(func(idx int, val state.ReadOnlyValidator) error {
		e := val.ExitEpoch()
		if e != farFutureEpoch {
			if e > exitInfo.HighestExitEpoch {
				exitInfo.HighestExitEpoch = e
				exitInfo.Churn = 1
			} else if e == exitInfo.HighestExitEpoch {
				exitInfo.Churn++
			}
```

So it simply increases the churn for each validator that has epoch equal to the highest exit epoch.

The function `InitiateValidatorExit` mutates this pointer in the following way

if the state is post-electra, it disregards completely this pointer and computes the highest exit epoch and updates churn inconditionally, so the pointer `exitInfo.HighestExitEpoch` will always have the right value and is not even neded to be computed before. We could even avoid the fist loop even. If the state is pre-Electra then the function itself updates correctly the exit info for the next iteration.

* Only care about exits pre-Electra

* Update beacon-chain/core/transition/transition_no_verify_sig.go

2292d955a3 PeerDAS: Implement syncing in a disjoint network (Also know as "perfect PeerDAS" network). (#15644)
* `computeIndicesByRootByPeer`: Add 1 slack epoch regarding peer head slot.

* `FetchDataColumnSidecars`: Switch mode.

Before this commit, this function returned on error as long as at least ONE requested sidecar was not retrieved.

Now, this function retrieves what it can (best effort mode) and returns an additional value which is the map of missing sidecars after running this function.

It is now the role of the caller to check this extra returned value and decide what to do in case some requested sidecars are still missing.

* `fetchOriginDataColumnSidecars`: Optimize

Before this commit, when running `fetchOriginDataColumnSidecars`, all the missing sidecars had to been retrieved in a single shot for the sidecars to be considered as available. The issue was, if for example `sync.FetchDataColumnSidecars` returned all but one sidecar, the returned sidecars were NOT saved, and on the next iteration, all the previously fetched sidecars had to be requested again (from peers.)

After this commit, we greedily save all fetched sidecars, solving this issue.

* Initial sync: Do not fetch data column sidecars before the retention period.

* Implement perfect peerdas syncing.
