What is bitcoin and how they work?
***Cryptocurrency is a digital or virtual form of currency that uses cryptography for security. Unlike traditional currencies issued by governments (like the US dollar or euro), cryptocurrencies operate independently of any central authority. Here’s how they work:
1. **Decentralization**: Cryptocurrencies typically use a technology called blockchain, which is a decentralized technology spread across many computers that manage and record transactions. This decentralization ensures no single entity has control over the currency.
2. **Cryptography**: Transactions in cryptocurrencies are secured through cryptographic techniques, making it extremely difficult to counterfeit or double-spend coins.
3. **Transactions**: When someone sends cryptocurrency to another person, the transaction is broadcast to the network of computers (nodes) running the cryptocurrency's software. These nodes validate the transaction and add it to a public ledger (blockchain).
4. **Mining**: Some cryptocurrencies (like Bitcoin) use a process called mining to validate transactions. Miners use powerful computers to solve complex mathematical puzzles that verify transactions. In return for their efforts, miners are rewarded with newly created coins.
5. **Wallets**: Cryptocurrencies are stored in digital wallets, which can be software-based (online or offline) or hardware-based (physical devices). Each wallet has a unique address on the blockchain, similar to a bank account number.
6. **Value and Exchange**: Like traditional currencies, cryptocurrencies can be used to buy goods and services where accepted. Their value is determined by market demand and supply dynamics, as well as speculation.
Overall, cryptocurrencies offer a decentralized and potentially more secure way to transfer and store value, though they come with risks such as price volatility and regulatory uncertainty.
