The blockchain technology is the underlying framework that cryptocurrencies such as Bitcoin, Ethereum, and Litecoin run on. This technology provides a secure and transparent platform from which digital transactions can occur. The distributed ledger of the blockchain records and verifies all transactions taking place, ensuring reliable security for each transaction. This allows for decentralized networks and trustless transactions between two parties. Furthermore, the encryption methods employed by the blockchain technology help protect users’ personal information from being leaked or stolen. In summary, the blockchain technology provides the foundation for cryptocurrencies and enables them to operate securely and efficiently.
