An online digital currency known as a cryptocurrency It is not governed by a central authority like a bank or the government, unlike conventional money. Although thousands of other cryptocurrencies exist today, Bitcoin was the first. Blockchain

Bitcoin is the first and most well-known cryptocurrency. Due to its limited availability and potential for long-term value, many consider it to be “digital gold.” Altcoins
Altcoins are merely alternative cryptocurrencies to Bitcoin. Popular examples include Ethereum, Solana, Cardano, and Litecoin. Some concentrate on speed, privacy, or scalability, while others focus on smart contracts. Wallet
A crypto wallet is where you store your digital assets. It doesn’t hold physical coins—it holds your private keys, which give you access to your crypto. Online and offline wallets can be hot or cold. Private Key
One of the most important terms to know is this one. Similar to a password, a private key gives you complete control over your cryptocurrency. If someone gets it, they can access your funds. If you lose it, your cryptocurrency could be lost forever. Address and Public Key To receive cryptocurrency, you must share a public address with other people. It’s similar to a bank account number.

It is frequently regarded as an alternative to mining that uses less energy. “Decentralized finance” or “DeFi” Financial services built without banks or other intermediaries using blockchain technology are referred to as DeFi. This includes lending, borrowing, and earning interest directly through smart contracts.
Smart Contracts Smart contracts are self-executing programs on the blockchain. The contract automatically begins when the conditions are satisfied. No middlemen.
