Notes

A blockchain is a ledger of blocks linked into a chain: each block’s hash includes the previous block’s prev-hash. Mining (PoW) = searching for a nonce until the hash has enough leading zeros. Edit one block → the chain breaks for all later blocks ⇒ immutable. The basis of Bitcoin & distributed finance.
