Technical principles | How can a group of mutually distrustful nodes agree on the same ledger?
Classic BFT protocols require the total number of nodes to be at least three times the number of malicious nodes plus one—in other words, malicious nodes must make up less than one-third of the total.
Many proof-of-stake chains combine BFT voting with staking: voting power is based on the amount staked, and validators who break the rules have their stake slashed.
$ATOM is the native coin of Cosmos Hub, a blockchain that uses a Byzantine fault-tolerant consensus mechanism.
Every reward comes with its own risks, so take a closer look at the worst-case scenarios.
