Proof of Work (PoW) Meaning: What Does Proof of Work (PoW) Mean in Crypto?
Definition
Consensus mechanism requiring miners to solve complex mathematical puzzles
PoW, used by Bitcoin, ensures security through computational expense but faces criticism for environmental impact; it has proven resilient against attacks for over 16 years. Technical Details: Bitcoin Target Time: 10 minutes per block. Difficulty Adjustment: Every 2016 blocks (~2 weeks). Hash Algorithm: SHA-256 double hash. Security Analysis: 51% attack cost for Bitcoin: >$15 billion in hardware + ongoing electricity costs.
