## 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
