Metadata put to good use.

Using pixel data from a photo combined with an EmojiKey, PhotoBlock generates a blockchain address and public key that is embedded into the photo as metadata using Adobe XMP.

Blockchain-agnostic

Any blockchain. Any context.

Designed with as few dependencies as possible, PhotoBlock is an Open Source and framework-agnostic JavaScript library. Authenticate on Web2.0 without an extension.

Secure authentication

Two-factor authentication.

PhotoBlock requires both an EmojiKey and a photo, requiring two-factor authentication without phone numbers, emails, or authentication codes.

Private key management

Private keys stay private.

PhotoBlock does not store private keys. It generates a user's private key on-demand for secure and simple authentication.
