Run a Slasher using prysm.sh
General
The slasher's purpose is to find malicious validators in the Ethereum 2.0 network and report slashable offenses to the beacon-node.
How does the slasher work?
The slasher is its own entity but requires a beacon-node to receive attestations.
To find malicious activity by validators, the slashers iterates through all received attestations until a slashable offense is found. Found slashings are broadcasted to the network and the next block proposer adds the proof to the block. The block proposer get the reward for slashing - not the whistleblower(=Slasher).
Run a slasher
Make sure your beacon-node is in sync.
If you need to run a beacon-node and validator, here is a guide for Windows and here for macOS.
Step 1.
Drag and drop the prysm.sh file into the Terminal window and add:
slasher --datadir=$HOME/prysm
That's it!
The slasher now iterates through all attestations and sends proof to the detection service.
Debug mode enabled with
--verbosity=debugFor selfish slashing, add
--disable-broadcast-slashings to the beaconnode.
