Ever wonder how blockchains stay secure? The answer lies in consensus mechanisms. Proof‑of‑Work powers Bitcoin with computational puzzles tied to electricity. Proof‑of‑Stake lets holders stake coins to validate blocks, cutting energy use. New hybrids like PoS‑PoW, DPoS, and BFT variants aim to blend speed, decentralization, and sustainability. Stay curious.
