Removes the remaining facade re-exports from `consensus/types`.
I have left `graffiti` as I think it has some utility so am leaning towards keeping it in the final API design.

Remove `service_name` from `TaskExecutor`
Co-Authored-By: Abhivansh <31abhivanshj@gmail.com>
There are certain crates which we re-export within `types` which creates a fragmented DevEx, where there are various ways to import the same crates.
```rust
// consensus/types/src/lib.rs
pub use bls::{
AggregatePublicKey, AggregateSignature, Error as BlsError, Keypair, PUBLIC_KEY_BYTES_LEN,
PublicKey, PublicKeyBytes, SIGNATURE_BYTES_LEN, SecretKey, Signature, SignatureBytes,
get_withdrawal_credentials,
};
pub use context_deserialize::{ContextDeserialize, context_deserialize};
pub use fixed_bytes::FixedBytesExtended;
pub use milhouse::{self, List, Vector};
pub use ssz_types::{BitList, BitVector, FixedVector, VariableList, typenum, typenum::Unsigned};
pub use superstruct::superstruct;
```
This PR removes these re-exports and makes it explicit that these types are imported from a non-`consensus/types` crate.

Previously, we had a pinned version of `alloy` to fix some crate compatibility issues we encountered during the migration away from `ethers`. Now that the migration is complete we should remove the pin. This also updates alloy crates to their latest versions.

This pull request introduces workflows and updates to ensure reproducible builds for the Lighthouse project. It adds two GitHub Actions workflows for building and testing reproducible Docker images and binaries, updates the `Makefile` to streamline reproducible build configurations, and modifies the `Dockerfile.reproducible` to align with the new build process. Additionally, it removes the `reproducible` profile from `Cargo.toml`.
### New GitHub Actions Workflows:
* [`.github/workflows/docker-reproducible.yml`](diffhunk://#diff-222af23bee616920b04f5b92a83eb5106fce08abd885cd3a3b15b8beb5e789c3R1-R145): Adds a workflow to build and push reproducible multi-architecture Docker images for releases, including support for dry runs without pushing an image.
### Build Configuration Updates:
* [`Makefile`](diffhunk://#diff-76ed074a9305c04054cdebb9e9aad2d818052b07091de1f20cad0bbac34ffb52L85-R143): Refactors reproducible build targets, centralizes environment variables for reproducibility, and updates Docker build arguments for `x86_64` and `aarch64` architectures.
* [`Dockerfile.reproducible`](diffhunk://#diff-587298ff141278ce3be7c54a559f9f31472cc5b384e285e2105b3dee319ba31dL1-R24): Updates the base Rust image to version 1.86, removes hardcoded reproducibility settings, and delegates build logic to the `Makefile`.
* Switch to using jemalloc-sys from Debian repos instead of building it from source. A Debian version is [reproducible](https://tests.reproducible-builds.org/debian/rb-pkg/trixie/amd64/jemalloc.html) which is [hard to achieve](https://github.com/NixOS/nixpkgs/issues/380852) if you build it from source.
### Profile Removal:
* [`Cargo.toml`](diffhunk://#diff-2e9d962a08321605940b5a657135052fbcef87b5e360662bb527c96d9a615542L289-L295): Removes the `reproducible` profile, simplifying build configurations and relying on external tooling for reproducibility.

#6022
Migrate the `execution_engine_integration` tests to the `alloy` ecosystem. This removes the last remaining `ethers` dependencies
Co-Authored-By: Mac L <mjladson@pm.me>
Another good candidate for publishing separately from Lighthouse is `sensitive_url` as it's a general utility crate and not related to Ethereum. This PR prepares it to be spun out into its own crate.
I've made the `full` field on `SensitiveUrl` private and instead provided an explicit getter called `.expose_full()`. It's a bit ugly for the diff but I prefer the explicit nature of the getter.
I've also added some extra tests and doc strings along with feature gating `Serialize` and `Deserialize` implementations behind the `serde` feature.

`beacon-chain-tests` is now regularly taking 1h+ on CI since Fulu fork was added.
This PR attemtpts to reduce the test time by bringing down the number of blobs generated in tests - instead of generating 0..max_blobs, the generator now generates 0..1 blobs by default, and this can be modified by setting `harness.execution_block_generator.set_min_blob_count(n)`.
Note: The blobs are pre-generated and doesn't require too much CPU to generate however processing a larger number of them on the beacon chain does take a lot of time.
This PR also include a few other small improvements
- Our slowest test (`chain_segment_varying_chunk_size`) runs 3x faster in Fulu just by reusing chain segments
- Avoid re-running fork specific tests on all forks
- Fix a bunch of tests that depends on the harness's existing random blob generation, which is fragile
beacon chain test time on test machine is **~2x** faster:
### `unstable`
```
Summary [ 751.586s] 291 tests run: 291 passed (13 slow), 0 skipped
```
### this branch
```
Summary [ 373.792s] 291 tests run: 291 passed (2 slow), 0 skipped
```
The next set of tests to optimise is the ones that use [`get_chain_segment`](77a9af96de/beacon_node/beacon_chain/tests/block_verification.rs (L45)), as it by default build 320 blocks with supernode - an easy optimisation would be to build these blocks with cgc = 8 for tests that only require fullnodes.

The beacon API spec wasn't updated to use the Fulu definition of `dependent_root` for the proposer duties endpoint. No other client updated their logic, so to retain backwards compatibility the decision has been made to continue using the block root at the end of epoch `N - 1`, and introduce a new v2 endpoint down the track to use the correct dependent root.
Eth R&D discussion: https://discord.com/channels/595666850260713488/598292067260825641/1433036715848765562
Change the behaviour of the v1 endpoint back to using the last slot of `N - 1` rather than the last slot of `N - 2`. This introduces the possibility of dependent root false positives (the root can change without changing the shuffling), but causes the least compatibility issues with other clients.

Replace all instances of `VariableList::from` and `FixedVector::from` to their `try_from` variants.
While I tried to use proper error handling in most cases, there were certain situations where adding an `expect` for situations where `try_from` can trivially never fail avoided adding a lot of extra complexity.

Addresses #8218
A simplified version of #8241 for the initial release.
I've tried to minimise the logic change in this PR, although introducing the `NodeCustodyType` enum still result in quite a bit a of diff, but the actual logic change in `CustodyContext` is quite small.
The main changes are in the `CustdoyContext` struct
* ~~combining `validator_custody_count` and `current_is_supernode` fields into a single `custody_group_count_at_head` field. We persist the cgc of the initial cli values into the `custody_group_count_at_head` field and only allow for increase (same behaviour as before).~~
* I noticed the above approach caused a backward compatibility issue, I've [made a fix](15569bc085) and changed the approach slightly (which was actually what I had originally in mind):
* when initialising, only override the `validator_custody_count` value if either flag `--supernode` or `--semi-supernode` is used; otherwise leave it as the existing default `0`. Most other logic remains unchanged.
All existing validator custody unit tests are still all passing, and I've added additional tests to cover semi-supernode, and restoring `CustodyContext` from disk.
Note: I've added a `WARN` if the user attempts to switch to a `--semi-supernode` or `--supernode` - this currently has no effect, but once @eserilev column backfill is merged, we should be able to support this quite easily.
Things to test
- [x] cgc in metadata / enr
- [x] cgc in metrics
- [x] subscribed subnets
- [x] getBlobs endpoint

Anchor currently depends on `lighthouse_network` for a few types and utilities that live within. As we use our own libp2p behaviours, we actually do not use the core logic in that crate. This makes us transitively depend on a bunch of unneeded crates (even a whole separate libp2p if the versions mismatch!)
Move things we require into it's own lightweight crate.

Addresses #7866.
Use Rayon to speed up batch KZG verification during range / backfill sync.
While I was analysing the traces, I also discovered a bug that resulted in only the first 128 columns in a chain segment batch being verified. This PR fixes it, so we might actually observe slower range sync due to more cells being KZG verified.
I've also updated the handling of batch KZG failure to only find the first invalid KZG column when verification fails as this gets very expensive during range/backfill sync.
Adds the required boilerplate code for the Gloas (Glamsterdam) hard fork. This allows PRs testing Gloas-candidate features to test fork transition.
This also includes de-duplication of post-Bellatrix readiness notifiers from #6797 (credit to @dapplion)
Re-export `context_deserialize_derive` inside of `context_deserialize` so they are both available from the same interface, which matches how popular crates (like `serde`) handle this.
This also nests both crates inside a new `context_deserialize` directory which will make it easier to eventually spin out into a different repo (if/when) we decide to do that (plus I prefer it aesthetically).
This PR fixes a bug where wrong columns could get processed immediately after a CGC increase.
Scenario:
- The node's CGC increased due to additional validators attached to it (lets say from 10 to 11)
- The new CGC is advertised and new subnets are subscribed immediately, however the change won't be effective in the data availability check until the next epoch (See [this](ab0e8870b4/beacon_node/beacon_chain/src/validator_custody.rs (L93-L99))). Data availability checker still only require 10 columns for the current epoch.
- During this time, data columns for the additional custody column (lets say column 11) may arrive via gossip as we're already subscribed to the topic, and it may be incorrectly used to satisfy the existing data availability requirement (10 columns), and result in this additional column (instead of a required one) getting persisted, resulting in database inconsistency.
Fix Clippy for recently released Rust 1.90 beta. There may be more changes required when Rust 1.89 stable is released in a few days, but possibly not 🤞
I noticed that we are serving preset values for Fulu on mainnet nodes prior to the fork. This has already gone live in v7.1.0, but should hopefully be handled in a graceful way by API consumers.
This PR _reverts_ the serving of Fulu data prior to Fulu, by serving Fulu data only if Fulu is scheduled.
Update `c-kzg` from `v1` to `v2`. My motivation here is that `alloy-consensus` now uses `c-kzg` in `v2` and this results in a conflict when using lighthouse in combination with latest alloy. I tried also to disable the `czkg` feature in alloy, but the conflict persisted.
See here for the alloy update to `c-kzg v2`: https://github.com/alloy-rs/alloy/pull/2240
Error:
```
error: failed to select a version for `c-kzg`.
...
versions that meet the requirements `^1` are: 1.0.3, 1.0.2, 1.0.0
the package `c-kzg` links to the native library `ckzg`, but it conflicts with a previous package which links to `ckzg` as well:
package `c-kzg v2.1.0`
... which satisfies dependency `c-kzg = "^2.1"` of package `alloy-consensus v0.13.0`
... which satisfies dependency `alloy-consensus = "^0.13.0"` of package ...
...
```
- Upgrade `alloy-consensus` to `0.14.0` and disable all default features
- Upgrade `c-kzg` to `v2.1.0`
- Upgrade `alloy-primitives` to `1.0.0`
- Adapt the code to the new API `c-kzg`
- There is now `NO_PRECOMPUTE` as my understand from https://github.com/ethereum/c-kzg-4844/pull/545/files we should use `0` here as `new_from_trusted_setup_no_precomp` does not precomp. But maybe it is misleading. For all other places I used `RECOMMENDED_PRECOMP_WIDTH` because `8` is matching the recommendation.
- `BYTES_PER_G1_POINT` and `BYTES_PER_G2_POINT` are no longer public in `c-kzg`
- I adapted two tests that checking for the `Attestation` bitfield size. But I could not pinpoint to what has changed and why now 8 bytes less. I would be happy about any hint, and if this is correct. I found related a PR here: https://github.com/sigp/lighthouse/pull/6915
- Use same fields names, in json, as well as `c-kzg` and `rust_eth_kzg` for `g1_monomial`, `g1_lagrange`, and `g2_monomial`
N/A
After the electra fork which includes EIP 6110, the beacon node no longer needs the eth1 bridging mechanism to include new deposits as they are provided by the EL as a `deposit_request`. So after electra + a transition period where the finalized bridge deposits pre-fork are included through the old mechanism, we no longer need the elaborate machinery we had to get deposit contract data from the execution layer.
Since holesky has already forked to electra and completed the transition period, this PR basically checks to see if removing all the eth1 related logic leads to any surprises.
Resolves#6767
This PR implements a basic version of validator custody.
- It introduces a new `CustodyContext` object which contains info regarding number of validators attached to a node and the custody count they contribute to the cgc.
- The `CustodyContext` is added in the da_checker and has methods for returning the current cgc and the number of columns to sample at head. Note that the logic for returning the cgc existed previously in the network globals.
- To estimate the number of validators attached, we use the `beacon_committee_subscriptions` endpoint. This might overestimate the number of validators actually publishing attestations from the node in the case of multi BN setups. We could also potentially use the `publish_attestations` endpoint to get a more conservative estimate at a later point.
- Anytime there's a change in the `custody_group_count` due to addition/removal of validators, the custody context should send an event on a broadcast channnel. The only subscriber for the channel exists in the network service which simply subscribes to more subnets. There can be additional subscribers in sync that will start a backfill once the cgc changes.
TODO
- [ ] **NOT REQUIRED:** Currently, the logic only handles an increase in validator count and does not handle a decrease. We should ideally unsubscribe from subnets when the cgc has decreased.
- [ ] **NOT REQUIRED:** Add a service in the `CustodyContext` that emits an event once `MIN_EPOCHS_FOR_BLOB_SIDECARS_REQUESTS ` passes after updating the current cgc. This event should be picked up by a subscriber which updates the enr and metadata.
- [x] Add more tests
Our basic sim test has been [flaky](https://github.com/sigp/lighthouse/actions/runs/15458818777/job/43515966229) for some time, and seems like it has gotten worse since electra fork was added to it in #7199.
It looks like the github runner is struggling with the load, currently it runs 7 nodes on a 4 CPU runner, which is definitely too much. We could consider moving this to run on our self hosted runner - but I think running 7 nodes is unnecessary and we can probably trim test this down.
Reduce number of basic sim test nodes from 7 (3 BN + 3 Proposer BN + 1 extra) to 4 (2 BN + 1 Proposer BN + 1 extra).
If we want to run more nodes, we'd have to consider running on self hosted runners.
This PR adds the ability to download [nightly reference tests from the consensus-specs repo](https://github.com/ethereum/consensus-specs/actions/workflows/generate_vectors.yml). This will be used by spec maintainers to ensure that there are no unexpected test failures prior to new releases. Also, we will keep track of test compliance with [this website](https://jtraglia.github.io/nyx/); eventually this will be integrated into Hive.
* A new script (`download_test_vectors.sh`) is added to handle downloads.
* The logic for downloading GitHub artifacts is a bit complex.
* Rename the variables which store test versions:
* `TESTS_TAG` to `CONSENSUS_SPECS_TEST_VERSION`.
* `BLS_TEST_TAG` to `BLS_TEST_VERSION`, for consistency.
* Delete tarballs after extracting them.
* I see no need to keep these; they just use extra disk.
* Consolidate `clean` rules into a single rule.
* Do `clean` prior to downloading/extracting tests.
* Remove `CURL` variable with GitHub token; don't need it for downloading releases.
* Do `mkdir -p` when creating directories.
* Probably more small stuff...
