## Proposed Changes
Adds support for the [Toledo](https://github.com/protolambda/toledo) dev-net.
```bash
lighthouse --testnet toledo bn --http
```
This is for development only, we do not recommend users to join this testnet.
## Additional Info
- ~~Blocked on #1862~~
The remote signer relies on the `types` and `crypto/bls` crates from Lighthouse. Moreover, a number of tests of the remote signer consumption of LH leverages this very signer, making any important update a potential dependency nightmare.

## Issue Addressed
Closes#1842
## Proposed Changes
Due to the lies told to us by VPS providers about what CPU features they support, we are forced to check for the availability of CPU features like ADX by just _running code and seeing if it crashes_. The prominent warning should hopefully help users who have truly incompatible CPUs work out what is going on, while not burdening users of cheap VPSs.
## Issue Addressed
Closes#1504Closes#1505
Replaces #1703Closes#1707
## Proposed Changes
* Update BLST and Milagro to versions compatible with BLSv4 spec
* Update Lighthouse to spec v1.0.0-rc.0, and update EF test vectors
* Use the v1.0.0 constants for `MainnetEthSpec`.
* Rename `InteropEthSpec` -> `V012LegacyEthSpec`
* Change all constants to suit the mainnet `v0.12.3` specification (i.e., Medalla).
* Deprecate the `--spec` flag for the `lighthouse` binary
* This value is now obtained from the `config_name` field of the `YamlConfig`.
* Built in testnet YAML files have been updated.
* Ignore the `--spec` value, if supplied, log a warning that it will be deprecated
* `lcli` still has the spec flag, that's fine because it's dev tooling.
* Remove the `E: EthSpec` from `YamlConfig`
* This means we need to deser the genesis `BeaconState` on-demand, but this is fine.
* Swap the old "minimal", "mainnet" strings over to the new `EthSpecId` enum.
* Always require a `CONFIG_NAME` field in `YamlConfig` (it used to have a default).
## Additional Info
Lots of breaking changes, do not merge! ~~We will likely need a Lighthouse v0.4.0 branch, and possibly a long-term v0.3.0 branch to keep Medalla alive~~.

## Proposed Changes
- Implements a HTTP API for the validator client.
- Creates EIP-2335 keystores with an empty `description` field, instead of a missing `description` field. Adds option to set name.
- Be more graceful with setups without any validators (yet)
- Remove an error log when there are no validators.
- Create the `validator` dir if it doesn't exist.
- Allow building a `ValidatorDir` without a withdrawal keystore (required for the API method where we only post a voting keystore).
- Add optional `description` field to `validator_definitions.yml`
## TODO
- [x] Signature header, as per https://github.com/sigp/lighthouse/issues/1269#issuecomment-649879855
- [x] Return validator descriptions
- [x] Return deposit data
- [x] Respect the mnemonic offset
- [x] Check that mnemonic can derive returned keys
- [x] Be strict about non-localhost
- [x] Allow graceful start without any validators (+ create validator dir)
- [x] Docs final pass
- [x] Swap to EIP-2335 description field.
- [x] Fix Zerioze TODO in VC api types.
- [x] Zeroize secp256k1 key
## Endpoints

## Issue Addressed
Implements support for importing and exporting the slashing protection DB interchange format described here:
https://hackmd.io/@sproul/Bk0Y0qdGD
Also closes#1584
## Proposed Changes
* [x] Support for serializing and deserializing the format
* [x] Support for importing and exporting Lighthouse's database
* [x] CLI commands to invoke import and export
* [x] Export to minimal format (required when a minimal format has been previously imported)
* [x] Tests for export to minimal (utilising mixed importing and attestation signing?)
* [x] Tests for import/export of complete format, and import of minimal format
* [x] ~~Prevent attestations with sources less than our max source (Danny's suggestion). Required for the fake attestation that we put in for the minimal format to block attestations from source 0.~~
* [x] Add the concept of a "low watermark" for compatibility with the minimal format
Bonus!
* [x] A fix to a potentially nasty bug involving validators getting re-registered each time the validator client ran! Thankfully, the ordering of keys meant that the validator IDs used for attestations and blocks remained stable -- otherwise we could have had some slashings on our hands! 😱
* [x] Tests to confirm that this bug is indeed vanquished
Closes#1487Closes#1427
Directory restructure in accordance with #1487. Also has temporary migration code to move the old directories into new structure.
Also extracts all default directory names and utility functions into a `directory` crate to avoid repetitio.
~Since `validator_definition.yaml` stores absolute paths, users will have to manually change the keystore paths or delete the file to get the validators picked up by the vc.~. `validator_definition.yaml` is migrated as well from the default directories.

## Issue Addressed
- Resolves#1313
## Proposed Changes
Changes the way we start the validator client and beacon node to ensure that we cleanly drop the validator keystores (which therefore ensures we cleanup their lockfiles).
Previously we were holding the validator keystores in a tokio task that was being forcefully killed (i.e., without `Drop`). Now, we hold them in a task that can gracefully handle a shutdown.
Also, switches the `--strict-lockfiles` flag to `--delete-lockfiles`. This means two things:
1. We are now strict on lockfiles by default (before we weren't).
1. There's a simple way for people delete the lockfiles if they experience a crash.
## Additional Info
I've only given the option to ignore *and* delete lockfiles, not just ignore them. I can't see a strong need for ignore-only but could easily add it, if the need arises.
I've flagged this as `api-breaking` since users that have lockfiles lingering around will be required to supply `--delete-lockfiles` next time they run.
## Issue Addressed
Resolves#1651
## Description
This supercedes #1658. Great work was done by @pawanjay176, I just needed to make a change whilst he is away.
See #1658 for a description, prior reviews and approval by @michaelsproul.
## Additional info
Ignores a rustsec advisory. This is tracked in #1669.

## Proposed Changes
Update test vectors for v0.12.3, and introduced configurable `proportional_slashing_multiplier`.
Also makes `YamlConfig` a bit safer by making every field access in `apply_to_chain_spec` explicit, and removing the `#[serde(default)]` attribute, which would instantiate missing fields to type defaults! Risky!
## Issue Addressed
#1437
## Proposed Changes
- Make the `--wallet-password` flag optional and creates an interactive prompt if not provided.
- Make the `--wallet-name` flag optional and creates an interactive prompt if not provided.
- Add a minimum password requirement of a 12 character length.
- Update the `--stdin-passwords` flag to `--stdin-inputs` because we have non-password user inputs
## Additional Info
This reverts commit 4fca306397.
Something in the BLST update is causing SIGILLs on aarch64 non-portable builds. While we debug the issue, I think it's best if we just revert the update.
## Issue Addressed
Closes#1504
Closes https://github.com/sigp/lighthouse/issues/1505
## Proposed Changes
* Update `blst` to the latest version, which is more portable and includes finer-grained compilation controls (see below).
* Detect the case where a binary has been explicitly compiled with ADX support but it's missing at runtime, and report a nicer error than `SIGILL`.
## Known Issues
* None. The previous issue with `make build-aarch64` (https://github.com/supranational/blst/issues/27), has been resolved.
## Additional Info
I think we should tweak our release process and our Docker builds so that we provide two options:
Binaries:
* `lighthouse`: compiled with `modern`/`force-adx`, for CPUs 2013 and newer
* `lighthouse-portable`: compiled with `portable` for older CPUs
Docker images:
* `sigp/lighthouse:latest`: multi-arch image with `modern` x86_64 and vanilla aarch64 binary
* `sigp/lighthouse:latest-portable`: multi-arch image with `portable` builds for x86_64 and aarch64
And relevant Docker images for the releases (as per https://github.com/sigp/lighthouse/pull/1574#issuecomment-687766141), tagged `v0.x.y` and `v0.x.y-portable`
## Issue Addressed
N/A
## Proposed Changes
- Fix a wrong command in the validator generation example.
- Replace occurrences of 'passphrase' with 'password'. This is mostly because I felt that there was a lot of mixing of the two phrases in the documentation and the actual commands which is a bit confusing. Picked 'password' everywhere because it felt more appropriate but I don't mind changing it to 'passphrase' as long it's consistent everywhere.

Increase the slog-async log channel size from the default of 128 to 2048 to reduce the number of dropped logs.
## Additional Info
## Issue Addressed
Fixes#1552
## Proposed Changes
Earlier, we were always loading the hardcoded default testnet config which is a mainnet spec. So running lighthouse with `--spec` option anything other than mainnet gave errors because we tried loading a mainnet genesis spec with `minimal`/`interop` flags.
This PR fixes the order of loading such that we load the hardcoded default spec only if neither `--testnet` and `--testnet-dir` flags are present.
## Issue Addressed
NA
## Proposed Changes
Shift practically all HTTP endpoint handlers to the blocking executor (some very light tasks are left on the core executor).
## Additional Info
This PR covers the `rest_api` which will soon be refactored to suit the standard API. As such, I've cut a few corners and left some existing issues open in this patch. What I have done here should leave the API in state that is not necessary *exactly* the same, but good enough for us to run validators with. Specifically, the number of blocking workers that can be spawned is unbounded and I have not implemented a queue; this will need to be fixed when we implement the standard API.
## Issue Addressed
#1494
## Proposed Changes
- Give the TaskExecutor the sender side of a channel that a task can clone to request shutting down
- The receiver side of this channel is in environment and now we block until ctrl+c or an internal shutdown signal is received
- The swarm now informs when it has reached 0 listeners
- The network receives this message and requests the shutdown
## Discovery v5 update
In this update we remove the openssl dependency in favour of rust-crypto.
The update also removes a series of unnecessary async functions which may improve some of the issues we have been experiencing.
## Issue Addressed
N/A
## Proposed Changes
Earlier, to log to a file, the only options were to redirect stdout/stderr to a file or use json logging.
Redirecting to stdout/stderr works well but causes issues with mistakenly overwriting the file instead of appending which has resulted in loss of precious logs on multiple occasions for me.
Json logging creates a timestamped backup of the file if it already exists, but the json format itself is hugely annoying.
This PR modifies the `--logfile` option to log as it does in the terminal to a logfile.
## Issue Addressed
NA
## Proposed Changes
Adds support for using the [`cross`](https://github.com/rust-embedded/cross) project to produce cross-compiled binaries using Docker images.
Provides quite clean and simple cross-compiles cause all the complexity is hidden in Dockerfiles. It does require you to be in the `docker` group though.
## Details
- Adds shortcut commands to `Makefile`
- Ensures `reqwest` and `discv5` use vendored openssl libs (i.e., static not shared).
- Switches to a [commit](284f705964) of blst that has a renamed C function to avoid a collision with openssl (upstream issue: https://github.com/supranational/blst/issues/21).
- Updates `ring` to the latest satisfiable version, since an earlier version was causing issues with `cross`.
- Off-topic, but adds extra message about Windows support as suggested by Discord user.
## Additional Info
- ~~Blocked on #1495~~
- There are no tests in CI for this yet for a few reasons:
- I'm hesitant to add more long-running tasks.
- Short-term bitrot should be avoided since we'll use it each release.
- In the long term I think it would be good to automate binary creation on a release.
- I observed the binaries increase in size from 50mb to 52mb after these changes.
## Issue Addressed
#1483
## Proposed Changes
Upgrades the log to a critical if a listener fails. We are able to listen on many interfaces so a single instance is not critical. We should however gracefully shutdown the client if we have no listeners, although the client can still function solely on outgoing connections.
For now a critical is raised and I leave #1494 for more sophisticated handling of this.
This also updates discv5 to handle errors of binding to a UDP socket such that lighthouse is now able to handle them.
