Two of the biggest blockchain platforms are Ethereum and NEO. Ethereum popularized the idea of “Blockchain 2.0”, or using blockchain for more than just payments by using smart contracts, or self-executing contracts made of computer code, users can not only send money to each other in a decentralized way, but also build decentralized applications (Dapps), including decentralized financial services. another one is NEO in light of Ethereum’s explosion onto the blockchain scene, other competitors quickly emerged. One of these was NEO, also known as “The Chinese Ethereum” due to its origins in China. I like most ethereum.
