Your personal information is NOT stored on the blockchain. Blockpass simply stores a special identifier, called a ‘hash’, of your personal information. Once your information is verified, it is sealed in a digital packet and put through a ‘hashing’ mechanism. This process creates a random string of digits that represents your personal data. If even one pixel or letter in your personal data is changed, this hash will be 100% different. This process allows for an anonymous representation of your data to be stored without risk of a centralized data breach.
