KIK, a Canadian instant messaging social platform, announced the launch of its own digital currency, kin coin, which will allow users to buy a series of digital services. This digital currency called kin, like the most famous digital currency bitcoin, is based on Ethereum blockchain technology. KIK founder and CEO Ted Livingston said that KIK will become the first social media application to publicly sell digital currency. Kin is a cryptocurrency used for micro transactions in consumer applications. Millions of people earn and consume kin in an ecosystem of more than 50 applications, making it the most commonly used cryptocurrency for mainstream consumers. With just a few lines of code, developers can add kin to existing consumer applications and start a new profit model immediately. Developers are paid through the kin reward engine, which is similar to the bitcoin block reward, but it will pay developers for their users to earn and consume kin. Integrates kin's applications, including social applications, content platforms and games. Users spend kin on content, tip creators, and buy in-game items, and earn Kin by watching advertisements or filling out questionnaires. Kin is a growing small economy in the digital world, in which everyone's contribution is fairly rewarded.
