Today, new blockchain projects and cryptocurrencies are mushrooming. One of the most prominent is NEO (formerly Antshares). NEO is often referred to as the "Chinese Ethereum" or "Ethereum killer". NEO is the first decentralised, open source cryptocurrency and blockchain platform in China. Its stated goal is to be at the forefront of building a smart economy. The smart economy will always come from digital assets, digital identity and smart contracts. NEO is based on a very similar operating principle to Ethereum, but with some features that give it an edge, but which are clearly different. One of the greatest improvements is that it is compatible with multiple languages such as, Java, Kotlin, Go&Phyton. In contrast, Ethereum's support is limited to Solidity, a language developed by its own developers. If we approach it from this angle, it already attracts more developers. Wider adoption of programming languages reduces the barriers, developers don't need to learn a new language to write smart contracts or work with Neo. Another key difference is that there is no need for miners. They use accounting nodes, who are incentivised with rewards to keep the network running. In the near future, the aim is to create an ecosystem for smart contracts. The implementation of smart contracts requires a virtual machine (VM): a virtual machine that combines the beneficial features of all other currencies. For example, faster execution speed, better performance, even more complete control, support for the languages developed. NEO wallets are NEON Wallet, NEO GUI, NEO CLI, NEO Tracker, NEO Wallet, Antsy. NEO, NEO, NEO, AnS, NEO, AnS. NEO is a great project with the potential to match or even surpass Ethereum. Its biggest obstacle, and it is no small one, is the Chinese regulatory regime. After China's attempts to regulate the cryptocurrency industry and ban ICO projects, its future is somewhat uncertain. If China lifts its restrictions on ICOs, we can perhaps hope that it will become what many hope it will be and shake up the cryptocurrency market.
