This can include hardware wallets, encryption methods, and secure backup practices.Exchanges need to implement strong protocols to prevent hacks and data breaches. This includes measures like cold storage for funds, regular audits, and two-factor authentication for users.Overall, Full-Stack Security emphasizes that every layer of a cryptocurrency system must be secured, as vulnerabilities in any part can lead to significant risks. By applying robust security practices at each level, the integrity and trustworthiness of the system can be maintained, ultimately enhancing user confidence and adoption.
