Let’s talk about Byzantine fault tolerance.
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.
To be honest, I hadn’t paid attention to this before either: when holding large amounts of assets on a chain with very few validators, you need to realize that a handful of nodes colluding could sway the ledger.
$ATOM is the native coin of Cosmos Hub, a chain that uses a Byzantine fault-tolerant consensus mechanism. Currently 1.703.
If you’re unfamiliar with something, best to steer clear for now. Start by practicing with a small amount.
