Introduction to Virtual Currencies Virtual currencies, often referred to as cryptocurrencies, represent a new form of digital money. They are decentralized, meaning they are not controlled by any central authority like a government or financial institution. Fundamentals of Cryptography Cryptography plays a fundamental role in securing virtual currencies. It involves complex mathematical algorithms to encrypt and decrypt data, ensuring the integrity and confidentiality of transactions. Hashing Digital Signatures Hashing algorithms transform Digital signatures use data into unique and fixed- cryptography to ensure the length strings, known as hash authenticity and integrity of values. These hash values are digital documents or messages. used to verify the authenticity They provide a way to verify the and integrity of transactions. sender's identity and confirm that the content hasn't been tampered with. Encryption Encryption converts data into an unreadable format, making it secure during transmission or storage. This prevents unauthorized access and ensures the confidentiality of sensitive information. Understanding Digital Wallets and E-Wallets Digital wallets are software programs that store and manage virtual currencies. They act as digital containers for your cryptocurrency holdings, enabling you to send, receive, and store your assets securely. Digital Wallets E-Wallets Digital wallets are software programs that store E-wallets are digital wallets that allow users to and manage virtual currencies. They are designed store and manage electronic funds, including fiat to be secure and reliable, offering features such as currencies. They provide a convenient way to encryption and multi-signature authentication. make online payments and transactions. 1. Software wallets 1. Online wallets 2. Hardware wallets 2. Mobile wallets 3.
