NEO (NEOUSD) formerly known as Antshares (ANS), was successfully re-branded as NEO. This open source blockchain platform is also known as 'Chinese Ether'.
The NEO crypto platform was released on the 17th of October, 2016. As of now, around 50 million coins have been issued, and this number grows by 15 million coins per year. From the 1st of August, 2017, the limit rose to 100 million coins. It should be specially noted that NEO has partnered with large corporations such as Microsoft (Microsoft Azure) and Alibaba (Ali Cloud). This will significantly aid its profile and popularity.
The major difference between NEO and Ether is that you need to know Solidity to take part in Ether development, while NEO supports all well-known programming languages, with more developers being able to work with it.
