Zero-Trust Architecture is a security model based on the principle of never trusting any entity by default, whether inside or outside a network. In the realm of cryptocurrencies, this approach ensures that no single user, device, or network can be assumed safe.In practice, this means that every transaction, user, or interaction is subject to thorough verification. For example, before allowing access to funds or executing a smart contract, the system checks multiple factors such as user identity, device security, and transaction history. This model reduces the risk of fraud and unauthorized access, which are critical concerns in the use of cryptocurrencies. It also encourages strong authentication methods, such as multi-factor authentication, to bolster security measures.Overall, Zero-Trust Architecture helps create a more secure environment for cryptocurrency transactions by emphasizing continuous verification and minimizing reliance on trust.
