KEEP slashing

[pdyraga]

For a bonded ECDSA keep we should slash the minimum stake of KEEP of all signers (no attributability) in case of a fraudulent signature. Where a fraudulent signature is a valid but not requested one.

@Shadowfiend What is the incentive in tBTC for someone to report a signature fraud? Do we expect Keep to provide this incentive?

[Shadowfiend]

Fraud reporters get any remainder from the liquidation auction. The deposit owner is also incentivized to report fraud to get compensated for the ostensible theft of their BTC. A fraud reporter can basically get the whole ETH bond in case of provable misbehavior with some quick contract code.

Nice to hear, thanks. In this case, we'll just slash and don't care about tattletale reward.
