'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.'
IOTA is a distributed ledger for the Internet of Things. The first ledger with microtransactions without fees as well as secure data transfer. Quantum proof. IOTA is a ground breaking new open-source distributed ledger that does not use a blockchain. Its innovative new quantum-proof protocol, known as the Tangle, gives rise to unique new features like zero fees, infinite scalability, fast transactions, secure data transfer and many others. IOTA is initially focused on serving as the backbone of the Internet-of-Things (IoT). IOTA is a cryptocurrency that has no transaction fees and requires no miners in order to process transactions. It does, however, require some computational power to submit a transaction, making it perfect for machines to use as a currency and distributed communication protocol for the Internet of Things “IoT”. The main purpose of IOTA is to solve some of the major problems with Blockchain technology, the main one being that the bigger the Blockchain (such as Bitcoin), the slower, more expensive, and also more restricting it is to actually transfer funds. Another issue with the Blockchain is size, as more and more Blocks are added, the longer the Blockchain gets, and therefore the less amount of computers are able to mine it. Right now BTC is over 150GB long, and so is ETH. If this size increased tenfold, very few computers would be able to mine it at all. Making them relatively centralized (the top 2 Bitcoin mining pools own about 56% of hashing power).
