Inside SafePal S1 wallet, there implements a firmware verification mechanism that identifies and authenticates every firmware that is uploaded. For each SafePal firmware version, there will be a unique ID tagged to it. This unique ID is created based on the SHA-256 algorithm, an advanced cryptographic hash function used for data authentications. (Click to learn about What is SHA-256?)
