What Is ‘Double-Signing’ in PoS?

Double-signing is a malicious act where a validator signs two different blocks for the same slot or height on the blockchain. This attempts to create a fork and compromise the network's integrity.

It is a critical violation in PoS systems, and if detected, it immediately triggers the 'slashing' penalty to punish the attacker.
