Crate authority_round[−][src]
A blockchain engine that supports a non-instant BFT proof-of-authority.
It is recommended to use the two_thirds_majority_transition option, to defend against the
“Attack of the Clones”. Newly started networks can
set this option to 0, to use a 2/3 quorum from the beginning.
To support on-chain governance, the ValidatorSet is pluggable: Aura supports simple constant lists of validators as well as smart contract-based dynamic validator sets. Misbehavior is reported to the ValidatorSet as well, so that e.g. governance contracts can penalize or ban attacker’s nodes.
- “Benign” misbehavior are faults that can happen in normal operation, like failing to propose a block in your slot, which could be due to a temporary network outage, or wrong timestamps (due to out-of-sync clocks).
- “Malicious” reports are made only if the sender misbehaved deliberately (or due to a software bug), e.g. if they proposed multiple blocks with the same step number.
