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 Design notes are here https://hackmd.io/@sproul/HJSEklmPL
