     1  # Slasher Implementation
     2  
     3  This is the main project folder for a slasher implementation for Ethereum written in Go by [Prysmatic Labs](https://prysmaticlabs.com). A slasher listens for all broadcasted messages using a running beacon node in order to detect slashable attestations and block proposals. 
     4  It uses the [min-max-surround](https://github.com/protolambda/eth2-surround#min-max-surround) method by Protolambda.
     5  
     6  The slasher requires a connection to a synced beacon node in order to listen for attestations and block proposals. To run the slasher, type:
     7  ```
     8  bazel run //slasher -- \
     9      --datadir PATH/FOR/DB \
    10      --span-map-cache \
    11      --beacon-rpc-provider localhost:4000
    12  ```
    13  
    14  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.
