This penalty triggers when a validator signs two different blocks at the same time (i.e. attempts a double spend attack). If double-signing is detected, then the violating validator will be penalized with:
Burned FRA: burn 5% of FRA staked at validator
- i.e. if validator staked 100 tokens, then 5 FRA will be burned
This penalty triggers when a validator is offline. Since the availability of validators to contribute to voting is critical to securing a PoS blockchain, unreliable validators must be punished when they fall below the performance. For every missing block, 0.00001% of FRA staked at validator will be burned.
- i.e. if validator staked 100000 tokens, then 1 FRA will be burned when this validator miss one block.
