Ever wondered how Bitcoin and Ethereum actually agree on the truth? It’s all about consensus. Proof‑of‑Work (PoW) burns energy and locks in blocks by solving puzzles. Proof‑of‑Stake (PoS) lets validators lock coins and vote, cutting power use. New hybrids like PoS‑PoW, DPoS, and sharding aim to blend speed, security, and sustainability. Curious which will shape the next wave?

Want to keep crypto safe yet accessible? Quick cheat sheet: Hot wallets (mobile & desktop) are great for trading but vulnerable to hacks – keep only what you need. Cold wallets (hardware, paper, air‑gapped) are your fortress for long‑term storage – no internet, zero phishing risk. Semi‑cold options like hardware‑backed mobile wallets mix convenience and strong security. Lock up big balances; keep a small hot stash for trades.
