1st Generation Blockchain refers to the original blockchain technology, primarily associated with Bitcoin. Introduced in 2009 by an anonymous person or group known as Satoshi Nakamoto, it was designed to enable peer-to-peer transactions without intermediaries.The key feature of this generation is its focus on security and decentralization. Transactions are recorded on a public ledger that is immutable, meaning they cannot be altered once confirmed. This promotes transparency while maintaining user anonymity.1st Generation Blockchain is primarily transactional, allowing users to send and receive value across borders. Its simplicity has paved the way for broader adoption, making it the foundation of many other blockchain technologies.However, it has limitations, such as scalability and speed. Bitcoin’s transaction processing can be slow and costly during peak times. These constraints led to the development of newer generations, which aim to improve functionality and expand use cases beyond mere transactions.
