“A failure to understand proof of work is a failure to understand Bitcoin.” – Jack Mallers, BTC Prague Proof of Work is the mechanism that makes Bitcoin trustworthy. Here’s how it works in simple terms: 🔹 Thousands of computers worldwide race to solve a mathematical puzzle. 🔹 The winner adds the next “block” of transactions to Bitcoin’s ledger. 🔹 This process requires energy, which makes cheating extremely costly. 🔹 The system automatically adjusts so blocks are added about every 10 minutes. The result? A network that no one can control, no government can censor, and no single company can shut down. That’s why Proof of Work isn’t just a feature of Bitcoin — it’s the very reason Bitcoin works.
