How Cryptocurrency Works 1. Blockchain: Transactions are grouped into blocks and linked together in chronological order, forming a chain. Each block contains a unique code (hash) and the previous block's hash, ensuring data integrity. 2. Decentralization: Instead of a central authority, like a bank, validating transactions, multiple nodes (computers) in the network verify and agree on the validity of transactions through a consensus algorithm. 3. Cryptographic Security: Cryptocurrencies use advanced cryptographic techniques to secure transactions and control the creation of new units. Private and public keys enable secure ownership and transfer of digital assets. 4. Mining or Consensus: Depending on the cryptocurrency, consensus mechanisms vary. Bitcoin, for example, uses proof-of-work, where miners solve complex mathematical problems to validate transactions and add them to the blockchain. Other cryptocurrencies use different methods like proof-of-stake. 5. Wallets: Users...
