Everything You Need To Know About The Constantinople Hard Fork

 Ethereum  Constantinople Hard Fork is in just two days with the official fork  date being the 16th of January 2019. This fork is sure considered to be a  major event not only for those into Ethereum network but also for the  crypto community generally. ChangeNOW,  a leading non-custodial cryptocurrency exchange, is getting ready for  the upgrade together with Ethereum community and is explaining the  basics of Constantinople in the series of articles.First  of all, it is important to talk about hard forks. We went through some  tough ones recently — starting with the epic massacre of the Bitcoin  Cash Hash War and ending with two of the supposed Ethereum chain splits  actually robbing the users.Well,  no matter what happens, it is not the reason to feel threatened. Hard  forks are dramatic events in blockchain life, but they are surely  necessary for future development.To  start with the basics, a hard fork is a radical upgrade of a taken  network that creates a literal fork (two versions of one  blockchain) — one of the branches is running on a newer version and the  other utilises the older. Usually, it happens that the nodes using the  older version all gradually upgrade and the “old-school” chain dies out.Sometimes,  though, a split happens and two coins are derived from the single  blockchain (like it happened to Bitcoin Cash, for instance).Constantinople  is not going to bring us more coins but will be the beginning of PoS  transition and technical development of Ethereum network.
