Many people think Byzantine fault tolerance is simple, but this is the part that's easy to get wrong:
Bitcoin's proof of work uses a competition for computing power to decide who produces blocks, keeping the ledger consistent when honest nodes control the majority of the computing power.
The “two-thirds” threshold means that any two votes that pass must overlap in at least some honest nodes, so two mutually contradictory results cannot both pass.
When assessing a chain's security, look at how many validators there are and whether voting power is overly concentrated in the hands of a few nodes.
$ATOM is the native coin of Cosmos Hub, a chain that uses a Byzantine fault tolerant consensus mechanism.
