1. What is the Bitcoin blockchain?
The Bitcoin blockchain is a public digital ledger that records all Bitcoin transactions securely and transparently without any central authority.
2. How does Bitcoin ensure security and prevent fraud?
Bitcoin uses cryptography, digital signatures, and a process called proof-of-work, which makes altering or faking transactions nearly impossible.
3. What is Bitcoin mining?
Bitcoin mining is the process in which powerful computers solve complex puzzles to validate transactions and add new blocks to the blockchain, earning Bitcoin as a reward.
4. Can Bitcoin transactions be changed or deleted?
No. Once a transaction is confirmed and added to the blockchain, it becomes a permanent part of the public record and cannot be altered or removed.
5. Why is Bitcoin called a digital currency?
Bitcoin is called a digital currency because it exists only online, is not issued by any government, and can be transferred globally without traditional banks.
