Slasher Implementation

This is the main project folder for a slasher implementation for eth2 written in Go by Prysmatic Labs. A slasher listens for all broadcasted messages using a running beacon node in order to detect slashable attestations and block proposals. It uses the min-max-surround method by Protolambda.

The slasher requires a connection to a synced beacon node in order to listen for attestations and block proposals. To run the slasher, type:

bazel run //slasher -- \
    --datadir PATH/FOR/DB \
    --span-map-cache \
    --beacon-rpc-provider localhost:4000

The beacon node entered in beacon-rpc-provider will then receive slashings from the slasher client and send them to any requesting proposer to be put into a block. You can read more about configuration options for our slasher in our documentation portal
