Proof of Work secures networks such as Bitcoin by requiring miners to solve cryptographic puzzles. The difficulty adjusts to maintain steady block production, making attacks costly because adversaries must control the majority of hashing power.
Proof of Work (PoW)
TechnologyA consensus method where miners expend computational energy to propose blocks and earn rewards.
