## Proposed Changes
This is mostly a UX improvement.
Currently, when recursively finding keystores, we only ignore keystores with same path.This leads to potential issues while copying datadirs (e.g. copying datadir to a new ssd with more storage). After copying new datadir and starting the vc, we will discover the copied keystores as new keystores and add it to the definitions file leading to duplicate entries.
This PR avoids duplicate keystores being discovered as new keystore by checking for duplicate pubkeys as well.
## Issue Addressed

addresses some of #1712
unblocks #2076

## Proposed Changes
- Updates all the dependencies mentioned in #2129, except for web3. They haven't merged their tokio 1.0 update because they are waiting on some dependencies of their own. Since we only use web3 in tests, I think updating it in a separate issue is fine. If they are able to merge soon though, I can update in this PR.
- Updates `tokio_util` to 0.6.2 and `bytes` to 1.0.1.
- We haven't made a discv5 release since merging tokio 1.0 updates so I'm using a commit rather than release atm. **Edit:** I think we should merge an update of `tokio_util` to 0.6.2 into discv5 before this release because it has panic fixes in `DelayQueue` --> PR in discv5: https://github.com/sigp/discv5/pull/58
## Additional Info
tokio 1.0 changes that required some changes in lighthouse:
- `interval.next().await.is_some()` -> `interval.tick().await`
- `sleep` future is now `!Unpin` -> https://github.com/tokio-rs/tokio/issues/3028
- `try_recv` has been temporarily removed from `mpsc` -> https://github.com/tokio-rs/tokio/issues/3350
- stream features have moved to `tokio-stream` and `broadcast::Receiver::into_stream()` has been temporarily removed -> `https://github.com/tokio-rs/tokio/issues/2870
- I've copied over the `BroadcastStream` wrapper from this PR, but can update to use `tokio-stream` once it's merged https://github.com/tokio-rs/tokio/pull/3384

## Proposed Changes
Adds some metrics to track delays regarding:
- LH processing of blocks
- delays receiving blocks from other nodes.
## Additional Info

## Issue Addressed
- Resolves#2064
## Proposed Changes
Adds a `ValidatorMonitor` struct which provides additional logging and Grafana metrics for specific validators.
Use `lighthouse bn --validator-monitor` to automatically enable monitoring for any validator that hits the [subnet subscription](https://ethereum.github.io/eth2.0-APIs/#/Validator/prepareBeaconCommitteeSubnet) HTTP API endpoint.
Also, use `lighthouse bn --validator-monitor-pubkeys` to supply a list of validators which will always be monitored.
See the new docs included in this PR for more info.
## TODO
- [x] Track validator balance, `slashed` status, etc.
- [x] ~~Register slashings in current epoch, not offense epoch~~
- [ ] Publish Grafana dashboard, update TODO link in docs
- [x] ~~#2130 is merged into this branch, resolve that~~
## Issue Addressed
NA
## Proposed Changes
Copied from #2083, changes the config milliseconds_per_slot to seconds_per_slot to avoid errors when slot duration is not a multiple of a second. To avoid deserializing old serialized data (with milliseconds instead of seconds) the Serialize and Deserialize derive got removed from the Spec struct (isn't currently used anyway).
This PR replaces #2083 for the purpose of fixing a merge conflict without requiring the input of @blacktemplar.

## Issue Addressed
`test_dht_persistence` failing
## Proposed Changes
Bind `NetworkService::start` to an underscore prefixed variable rather than `_`. `_` was causing it to be dropped immediately
This was failing 5/100 times before this update, but I haven't been able to get it to fail after updating it

## Issue Addressed
Fixes#2141
Remove [tempdir](https://docs.rs/tempdir/0.3.7/tempdir/) in favor of [tempfile](https://docs.rs/tempfile/3.1.0/tempfile/).
## Proposed Changes
`tempfile` has a slightly different api that makes creating temp folders with a name prefix a chore (`tempdir::TempDir::new("toto")` => `tempfile::Builder::new().prefix("toto").tempdir()`).
So I removed temp folder name prefix where I deemed it not useful.
Otherwise, the functionality is the same.
## Issue Addressed
Catching up to a recently merged API spec PR: https://github.com/ethereum/eth2.0-APIs/pull/119
## Proposed Changes
- Return an SSZ beacon state on `/eth/v1/debug/beacon/states/{stateId}` when passed this header: `accept: application/octet-stream`.
- requests to this endpoint with no `accept` header or an `accept` header and a value of `application/json` or `*/*` , or will result in a JSON response

## Proposed Changes
This follows on from @blacktemplar's work in #2018.
- Allows the VC to connect to multiple BN for redundancy.
- Update the simulator so some nodes always need to rely on their fallback.
- Adds some extra deprecation warnings for `--eth1-endpoint`
- Pass `SignatureBytes` as a reference instead of by value.

## Issue Addressed
Replaces #2091
## Proposed Changes
* Delete the uncompressed genesis states from `eth2_network_config` after they were merged accidentally in #2029.
* Tweak the build script to not overwrite `genesis.ssz` on every build, which caused spurious rebuilds.
## Proposed Changes
Run cargo update and bump version in prep for v1.0.4 release
## Additional Info
Planning to merge this commit to `unstable`, test on Pyrmont and canary nodes, then push to `stable`.
## Issue Addressed
#1992 and #1987, and also to be considered a continuation of #1751
## Proposed Changes
many changed files but most are renaming to align the code with the semantics of `--network`
- remove the `--network` default value (in clap) and instead set it after checking the `network` and `testnet-dir` flags
- move `eth2_testnet_config` crate to `eth2_network_config`
- move `Eth2TestnetConfig` to `Eth2NetworkConfig`
- move `DEFAULT_HARDCODED_TESTNET` to `DEFAULT_HARDCODED_NETWORK`
- `beacon_node`s `get_eth2_testnet_config` loads the `DEFAULT_HARDCODED_NETWORK` if there is no network nor testnet provided
- `boot_node`s config loads the config same as the `beacon_node`, it was using the configuration only for preconfigured networks (That code is ~1year old so I asume it was not intended)
- removed a one year old comment stating we should try to emulate `https://github.com/eth2-clients/eth2-testnets/tree/master/nimbus/testnet1` it looks outdated (?)
- remove `lighthouse`s `load_testnet_config` in favor of `get_eth2_network_config` to centralize that logic (It had differences)
- some spelling
## Additional Info
Both the command of #1992 and the scripts of #1987 seem to work fine, same as `bn` and `vc`
## Issue Addressed
NA
## Proposed Changes
Updates out of date dependencies.
## Additional Info
See also https://github.com/sigp/lighthouse/issues/1712 for a list of dependencies that are still out of date and the resasons.
## Issue Addressed
Resolves#1434 (this is the last major feature in the standard spec. There are only a couple of places we may be off-spec due to recent spec changes or ongoing discussion)
Partly addresses #1669
## Proposed Changes
- remove the websocket server
- remove the `TeeEventHandler` and `NullEventHandler`
- add server sent events according to the eth2 API spec

Fixes a couple of low hanging fruits.
- Fixes#2037
- `validators-dir` and `secrets-dir` flags don't really need to depend upon each other
- Fixes#2006 and Fixes#1995
Update lighthouse to version `v1.0.2`.
There are two major updates in this version:
- Updates to the task executor to tokio 0.3 and all sub-dependencies relying on core execution, including libp2p
- Update BLST
## Description
This PR updates Lighthouse to tokio 0.3. It includes a number of dependency updates and some structural changes as to how we create and spawn tasks.
This also brings with it a number of various improvements:
- Discv5 update
- Libp2p update
- Fix for recompilation issues
- Improved UPnP port mapping handling
- Futures dependency update
- Log downgrade to traces for rejecting peers when we've reached our max

## Issue Addressed
part of #1883
## Proposed Changes
Adds a new cli argument `--eth1-endpoints` that can be used instead of `--eth1-endpoint` to specify a comma-separated list of endpoints. If the first endpoint returns an error for some request the other endpoints are tried in the given order.
## Additional Info
Currently if the first endpoint fails the fallbacks are used silently (except for `try_fallback_test_endpoint` that is used in `do_update` which logs a `WARN` for each endpoint that is not reachable). A question is if we should add more logs so that the user gets warned if his main endpoint is for example just slow and sometimes hits timeouts.
## Issue Addressed
Closes#1823
## Proposed Changes
* Use OS-level file locking for validator keystores, eliminating problems with lockfiles lingering after ungraceful shutdowns (`SIGKILL`, power outage). I'm using the `fs2` crate because it's cross-platform (unlike `file-lock`), and it seems to have the most downloads on crates.io.
* Deprecate + disable `--delete-lockfiles` CLI param, it's no longer necessary
* Delete the `validator_dir::Manager`, as it was mostly dead code and was only used in the `validator list` command, which has been rewritten to read the validator definitions YAML instead.
## Additional Info
Tested on:
- [x] Linux
- [x] macOS

## Proposed Changes
- Adds a HTTP server to the VC which provides Prometheus metrics.
- Moves the health metrics into the `lighthouse_metrics` crate so it can be shared between BN/VC.
- Sprinkle some metrics around the VC.
- Update the book to indicate that we now have VC metrics.
- Shifts the "waiting for genesis" logic later in the `ProductionValidatorClient::new_from_cli`
- This is worth attention during the review.
## Additional Info
- ~~`clippy` has some new lints that are failing. I'll deal with that in another PR.~~
## Issue Addressed
Boot nodes were being successfully created and publishing valid ENRs however the `eth2` field was not being saved to disk leading to a discrepancy between published ENR and disk ENR.
If the `eth2` field is known, it is now constructed in the initial ENR and saved to disk.
Previous mainnet bootnodes did not contain the `eth2` field and these have also been updated.
This is an implementation of a slasher that lives inside the BN and can be enabled via `lighthouse bn --slasher`.
Features included in this PR:
- [x] Detection of attester slashing conditions (double votes, surrounds existing, surrounded by existing)
- [x] Integration into Lighthouse's attestation verification flow
- [x] Detection of proposer slashing conditions
- [x] Extraction of attestations from blocks as they are verified
- [x] Compression of chunks
- [x] Configurable history length
- [x] Pruning of old attestations and blocks
- [x] More tests
Future work:
* Focus on a slice of history separate from the most recent N epochs (e.g. epochs `current - K` to `current - M`)
* Run out-of-process
* Ingest attestations from the chain without a resync

## Issue Addressed
- Resolves#1424
## Proposed Changes
Add a `GET lighthouse/staking` that returns 200 if the node is ready to stake (i.e., `--eth1` flag is present) or a 404 otherwise.
Whilst the VC is waiting for the genesis time to start (i.e., when the genesis state is known), check the `lighthouse/staking` endpoint and log an error if the node isn't configured for staking.
## Additional Info

## Issue Addressed

## Proposed Changes
- Caches later blocks than is required by `ETH1_FOLLOW_DISTANCE`.
- Adds logging to `warn` if the eth1 cache is insufficiently primed.
- Use `max_by_key` instead of `max_by` in `BeaconChain::Eth1Chain` since it's simpler.
- Rename `voting_period_start_timestamp` to `voting_target_timestamp` for accuracy.
## Additional Info
The reason for eating into the `ETH1_FOLLOW_DISTANCE` and caching blocks that are closer to the head is due to possibility for `SECONDS_PER_ETH1_BLOCK` to be incorrect (as is the case for the Pyrmont testnet on Goerli).
If `SECONDS_PER_ETH1_BLOCK` is too short, we'll skip back too far from the head and skip over blocks that would be valid [`is_candidate_block`](https://github.com/ethereum/eth2.0-specs/blob/v1.0.0/specs/phase0/validator.md#eth1-data) blocks. This was the case on the Pyrmont testnet and resulted in Lighthouse choosing blocks that were about 30 minutes older than is ideal.
## Issue Addressed
Closes#1889
## Proposed Changes
- Error when passwords which use invalid UTF-8 characters during encryption.
- Add some tests
## Additional Info
I've decided to error when bad characters are used to create/encrypt a keystore but think we should allow them during decryption since either the keystore was created
- with invalid UTF-8 characters (possibly by another client or someone whose password is random bytes) in which case we'd want them to be able to decrypt their keystore using the right key.
- without invalid characters then the password checksum would almost certainly fail.
Happy to add them to decryption if we want to make the decryption more trigger happy 😋 , it would only be a one line change and would tell the user which character index is causing the issue.
See https://eips.ethereum.org/EIPS/eip-2335#password-requirements
## Issue Addressed
Catching up on a few eth2 spec updates:
## Proposed Changes
- adding query params to the `GET pool/attestations` endpoint
- allowing the `POST pool/attestations` endpoint to accept an array of attestations
- batching attestation submission
- moving `epoch` from a path param to a query param in the `committees` endpoint

## Proposed Changes
Uses dynamic gossipsub scoring parameters depending on the number of active validators as specified in https://gist.github.com/blacktemplar/5c1862cb3f0e32a1a7fb0b25e79e6e2c.
## Additional Info
Although the parameters got tested on Medalla, extensive testing using simulations on larger networks is still to be done and we expect that we need to change the parameters, although this might only affect constants within the dynamic parameter framework.
## Issue Addressed

## Proposed Changes
Adds support for the [Toledo](https://github.com/protolambda/toledo) dev-net.
```bash
lighthouse --testnet toledo bn --http
