What exactly is blockchain? Many people can't explain it clearly!
Bitcoin produces a block every 10 minutes on average. Since switching to proof of stake, Ethereum produces a block every 12-second slot.
“Decentralization” means that no single institution controls the ledger. The protocol rules are written in code and carried out collectively by many nodes.
