'Kin is money for the digital world. It is an open micro-transaction platform used by millions of users across more than 50 consumer applications and services, making Kin the most used cryptocurrency by mainstream consumers. Kin can be sent anywhere in the world, instantly, and for free. Kin enters circulation via the Kin Rewards Engine, or ''KRE'', which rewards developers for getting their consumers to use Kin. Today people are using Kin to purchase a variety of digital goods and services and to support content creators. This offers developers a new business model that rewards the adoption of engaging experiences and free exchange of value between users, not harvesting their data and attention. That means users and developers are finally re-aligned, around a new economy in which those who generate value online are the focus, not big-data monopolies.'
Zen is a decentralized financial platform, built from scratch with the goal of providing people with a secure, scalable and useful infrastructure for creating their own financial instruments, and trading them directly without intermediaries.The Zen blockchain is secured by multiple proof-of-work algorithms, with token-holder voting on the balance between them. Multi-hash mining creates robust incentives for miners to deliver efficient, reliable security.Zen smart contracts are written and secured by a subset of the F* functional programming language, allowing users to: A) Prove the amount of resources a contract will consume and provide the necessary fees for running the contract to miners, removing the need for a “gas” based system.B) Prove their contracts meet a given specification, meaning they can prove the contract will definitely do (or not do) something given a specific set of parameters.The Zen platform comes with a built-in solution for oracles, which provide contracts with useful real world data.Finally, Zen is integrated with the Bitcoin blockchain, allowing contracts to observe and respond to native bitcoin transactions
