Proof of Stake vs Proof of Work: what's the difference and which is better?
Proof of Work (PoW) and Proof of Stake (PoS) are the two primary consensus mechanisms that secure blockchain networks. PoW, used by Bitcoin, relies on computational power and energy-intensive mining to validate transactions. PoS, used by Ethereum, selects validators based on the amount of cryptocurrency they stake as collateral. PoW offers proven security but high energy consumption, while PoS is far more energy-efficient and scalable but has a shorter track record. The choice isn't about which is universally better, but which is better suited for a network's specific goals regarding security, decentralization, and sustainability.
