Bitcoin is a decentralized digital currency, created in 2009 by an unknown person or group of people using the pseudonym Satoshi Nakamoto.
Blockchain Technology: Bitcoin transactions are recorded on a public ledger called the blockchain, which is maintained by a network of computers (nodes) through a process called mining.
Bitcoin transactions involve transferring value from one address to another, with each transaction being verified by miners and recorded on the blockchain.
Digital wallets are used to store, send, and receive bitcoins. Wallets can be hardware-based (cold wallets) or software-based (hot wallets).
