If a few nodes that lie get into the network, can the other nodes still reach agreement?
Byzantine fault tolerance is a topic worth understanding.
The “two-thirds” threshold means that any two votes that pass must share some honest nodes, so two conflicting results can’t both pass.
It’s safer to steer clear of things you don’t understand and practice with small amounts first.
$ATOM is the native coin of Cosmos Hub, whose blockchain uses a Byzantine fault-tolerant consensus mechanism.
