A new startup called Revealer is on a mission to create sound backup solutions for cryptocurrency mnemonic phrases and seeds. Just recently the company launched its first product dubbed ‘Revealer Zero’ – a small card system that visually encrypts and decrypts digital currency seed phrases or any alpha-numerical secret.Revealer Zero is a new product created by Tiago Romagnani Silveira that allows users to print and store cryptocurrency backups in a visually encrypted manner. The secret can be decrypted optically “without a computer or any special knowledge,” explains the company. Basically, each Revealer has a unique code with 128 bits of entropy encoded in hex format, while the last three digits represent a checksum. Entropy is the ‘randomness’ found in a computer’s operating system which is utilized in many types of computational cryptography like creating public and private key pairs.
“The version number indicates the dimension of the revealer, the 128 bits of entropy are used as random seed to generate the noise that is encoded on the card — The checksum offers some protection against a typing mistake,” explains the company’s website.
