Slashing Fees

Unavailability​

Slashing penalties are generally incurred because a node fails to successfully produce a block during its designated turn in the round-robin block-mining procedure as described in the Validator Election section.

  • If a validator node fails to mine 50 blocks in a row, the CORE token rewards the validator has accrued so far are slashed completely.
  • If they fail on the last 50 blocks of the round, they surrender everything they’ve earned.
  • If a validator fails to mine 150 blocks in a row, they surrender their share of the daily CORE token rewards, they lose 10% of the deposit made to become a validator, and they are jailed for three days, which means they aren’t eligible to be elected to the validator set.

Double Sign​

Anyone can submit a slash request on CoreChain with the evidence of Double Sign of CoreChain.

Evidence Validation​

  • Two block headers have the same height and the same parent block hash
  • Two block headers are sealed by the same validator
  • Two signatures of these two blocks must not be the same
  • The validator should be in the set of current round’s validators.

If the evidence is valid:

  1. 1,000 CORE would be slashed from the self-margined CORE of the validator
  2. The slashed validator would be jailed and barred from the network forever
  3. 500 of slashed CORE would be allocated to the submitter as a reward
  4. The rest of slashed CORE will transfer into System Reward Pool
