An AirGap Layer refers to a security approach used to protect sensitive information and digital assets, specifically cryptocurrencies. This method involves isolating critical systems or devices from internet connectivity, reducing the risk of unauthorized access or cyberattacks.In practice, an AirGap Layer means keeping a wallet, which stores digital currencies, on a standalone device that is never connected to the internet. This isolation helps safeguard private keys and sensitive data from hacking attempts and malware.When transactions need to be made, details can be securely transferred through other means, such as USB drives or QR codes. This ensures that although the air-gapped device hasn’t been compromised, users can still manage their assets safely.Overall, using an AirGap Layer significantly enhances security, making it a popular choice among individuals and organizations that prioritize the protection of their digital assets.
