How Does Cryptocurrency Work?

At the heart of every cryptocurrency is the blockchain — a public, tamper-proof ledger of transactions. Each block contains transaction data, and once verified, it's added to the chain permanently. This transparency ensures trust in the system.

Users store their coins in crypto wallets, which can be either hot (online) or cold (offline). Transactions are verified by miners or validators, depending on whether the coin uses Proof of Work (PoW) or Proof of Stake (PoS).
