NEO is a next generation smart economy platform (formerly Antshares) and China's first open source blockchain that was founded in 2014, is often known as the “Ethereum of China”. What is NEO? NEO uses a smart economy approach to implement its distributed network concept. Its main objective is to digitize assets using the decentralized network of blockchain technology and digital identity. Neo’s main aim is to be the distributed network for “smart economy”. As their website states: 'Digital Assets + Digital Identity + Smart Contract = Smart Economy.' Neo was developed by Shanghai-based blockchain R&D company “OnChain” and funded by two crowdsales: first crowdsale on October 2015 sold 17.5 million NEO tokens for $550,000 and the second crowdsale sold the remaining 22.5 million NEO tokens for $4.5 million. So why NEO? Asset digitization and identity on the NEO platform essentially creates a novel way for asset registration, issuance, and circulation. This means that tangible assets like real estate, company shares or even fiat money can be digitized and traded on the NEO network, thus giving rise to a whole new economy. Its digital identity system allows for integration between the platform and the real world economy. It has custom digital identity standards that enable the creation of electronic identity data for individuals, organizations and even entities. These electronic systems use multi-layered authentication models that include facial and voice recognition as well as fingerprints. All digital assets on the platform enjoy legal protection thanks to the use of digital certificates on its public blockchain. This, in turn, guarantees trust as the system offers an indelible and unalterable record of all entities’ holdings.
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).
