PhotoBlock provides user-friendly visual single sign-on for websites and blockchains

Photo + Emojis + OAuth + Blockchain = PhotoBlock

How PhotoBlock Works?

PhotoBlock works with a photo you provide (any JPEG will do) and your personal emoji sequence called an EmojiKey. The photo is transformed into a downloadable PhotoBlock file with embedded accounts for Web, Bitcoin and Ethereum (the three platforms currently supported). You can then use your PhotoBlock with your EmojiKey to unlock and access the accounts anywhere PhotoBlock is integrated.

PhotoBlock can be added to any dapp or website by a developer in just a few minutes, making it easy for users to authenticate and access the dapp/website without the hassle of usernames, passwords, private keys, mnemonic passphrases and generally everything that users dislike. Developers can focus on building awesome apps for their users — PhotoBlock does the rest!
