🔨 Mining
Mining is the process of solving a complex puzzle to validate a block. The first miner to solve it adds the block and receives a reward.
🔐 Proof-of-Work (PoW)
PoW ensures security and decentralization. It requires:
Time-consuming computation

Easy verification by others

Difficulty adjusting to maintain block timing

⚠️ Energy Concern:
PoW is secure but energy-intensive. Ethereum and others are now using Proof-of-Stake to save resources.
