Wakie is an app to set an alarm and get a phone call from a random Wakie community member. This is obviously similar to wake-up calls, such as those at hotels, but with a more adventurous human twist. In fact, a human alarm clock app is a unique idea, the concept is being patented in USPTO.

DailyBooth was a photoblogging website designed for users to take a photo of themselves every day with a caption, in order to document and share their life with others, thus the slogan "your life in pictures." It was similar to social-networking websites such as Twitter in that you could follow other users and allow them to follow you in turn and get real-time updates on what other people are doing.

Mission In 2008 Satoshi Nakamoto wrote Bitcoin: A peer-to-Peer electronic Cash System, and for the first time introduced a system that would allow a pure peer-to-peer version of electronic cash to be sent directly from one party to another without going through a financial institution. The underlying ethos of Blockchain has always been to shift the balance of the economic power away from centralized organizations through proliferation of the self-powered cryptographically secure digital self-ownership. In today's world of crypto, people are faced with a multitude of choices of how, when and where to transform their economic energy into self-custodial units of value. Fair Crypto Foundation aims to empower the individual in navigating the evolving world of cryptocurrencies through understanding of the first principles of Crypto. In our view, the first principles of Crypto are self-custody, transparency, trust through consensus, and permissionless value exchange without the counterparty risk as originally envisioned by Satoshi's white paper. Through research, development and community building, we aim to create more economic freedom defined as one's ability to direct their own economic energy without hindrance of centralized control systems. Who is behind Fair Crypto Foundation? The Fair Crypto Foundation concept has been devised by @mrJackLevin, an open source technologist and an early Google Engineer (β€˜99-05) and developed by a small group of partners - professionals in computer science, communications, software and product development, marketing and investments. The Foundation's goal is to carry out its vision through education, organization and launched Blockchain Projects embodying the first principles of Crypto.
