## Issue Addressed
Closes#1873
## Proposed Changes
Fixes the bug in slashing protection import (#1873) by pruning the database upon import.
Also expands the test generator to cover this case and a few others which are under discussion here:
https://ethereum-magicians.org/t/eip-3076-validator-client-interchange-format-slashing-protection/4883
## Additional Info
Depending on the outcome of the discussion on Eth Magicians, we can either wait for consensus before merging, or merge our preferred solution and patch things later.
## Issue Addressed
Closes#1790
## Proposed Changes
Make a new method that creates an empty transaction with `TransactionBehavior::Exclusive` to check whether the slashing protection is locked. Call this method before attempting to create or import new validator keystores.
## Additional Info

## Proposed Changes
Update the slashing protection interchange format to v5 in preparation for finalisation as part of an EIP.
Also, add some more tests and update the commit hash for https://github.com/eth2-clients/slashing-protection-interchange-tests to include the new generated tests.
It looks like the default docker image used by cross doesn't have
wget installed. This causes builds to fail. This can be fixed by
switching to curl.
## Issue Addressed
cross-compiling was broken (at least for build-aarch64)
## Proposed Changes
swap wget for curl
## Issue Addressed
- Resolves#1706
## Proposed Changes
Updates dependencies across the workspace. Any crate that was not able to be brought to the latest version is listed in #1712.
## Additional Info
NA
## 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
## Issue Addressed
NA
## Proposed Changes
- Refactor the `bls` crate to support multiple BLS "backends" (e.g., milagro, blst, etc).
- Removes some duplicate, unused code in `common/rest_types/src/validator.rs`.
- Removes the old "upgrade legacy keypairs" functionality (these were unencrypted keys that haven't been supported for a few testnets, no one should be using them anymore).
## Additional Info
Most of the files changed are just inconsequential changes to function names.
## TODO
- [x] Optimization levels
- [x] Infinity point: https://github.com/supranational/blst/issues/11
- [x] Ensure milagro *and* blst are tested via CI
- [x] What to do with unsafe code?
- [x] Test infinity point in signature sets
* Implement slashing protection
Roll-up of #588 with some conflicts resolved
* WIP improvements
* Require slot uniqueness for blocks (rather than epochs)
* Native DB support for Slot and Epoch
* Simplify surrounding/surrounded-by queries
* Implement unified slashing protection database
A single SQL database saves on open file descriptors.
* Make slashing protection concurrency safe.
Revive tests, add parallel tests.
* Some simplifications
* Auto-registration, test clean-ups
* More tests, clean-ups, hardening
* Fix comments in BLS
* Optimise bulk validator registration
* Delete outdated tests
* Use bundled SQLite in slashing protection
* Auto-register validators in simulation
* Use real signing_root in slashing protection
* Update book for --auto-register
* Refine log messages and help flags
* Correct typo in Cargo.toml authors
* Fix merge conflicts
* Safer error handling in sqlite slot/epoch
* Address review comments
* Add attestation test mutating block root
