Bitcoin and blockchain, while closely related, represent distinct concepts; Bitcoin is a decentralized cryptocurrency created in 2009 by an anonymous entity known as Satoshi Nakamoto, while blockchain is the underlying technology that supports it. Bitcoin was the first cryptocurrency and remains the most widely used, allowing transactions without the need for intermediaries such as banks. It is acquired through services or a complex mining process and exchanged for fiat currency via cryptocurrency platforms. On the other hand, blockchain serves as a distributed public ledger that securely records transactions without central authority intervention, made possible by decentralized peer-to-peer networks that verify and document exchanges. The technology's ability to facilitate secure, rapid, and low-cost global transactions has led to its consideration for various applications beyond finance, including e-voting and fraud prevention. Interest from major companies and financial institutions highlights a promising future for both Bitcoin and blockchain technologies.
