Ethereum Constantinople Hard-fork Announcement 2019

What is this Upcoming Ethereum hard- fork 

hard-fork is normally an update that will split a blockchain to 2 separate will cause to generate a brand new coin with new features and benefits(or improvement of current features ). we can see a few hard - forks for bitcoin such as bitcoin cash and bitcoin gold. Ethereum will fork current ethereum blockchain at block number 7,080,000. It will be near 16th or 17th January. the exact date can be varied with block time variation. A countdown timer can be seen at 

what kind of hard forks are there

Normally there are two kinds of hard forks 
  1. Non-contentious hard-forks
  2. Contentious hard-forks
Non-contentious hard-forks means most people stop running the old software(nodes) most people agree to use new features and no one will use old chain after the update. No one adds new blocks to that chain. The chain naturally slows and then dies. after these kinds of forks always old coins will die and useless. the newborn coin will bring past value and carry on with new features.
ex - ETH Homestead hard fork in 2016 

Contentious hard-forks means most of the people not stop running the old software(nodes) there are people who don’t agree with the changes being made. some people add new blocks to the old chain. The old chain also running as well as the new chain. after these kinds of forks always there will be two coins and both have some value
ex- BTC and BCH, ETH Byzantium hard fork in 2017 (ETC and ETH )

Is This Non-contentious hard-fork or Contentious hard-fork 

This is a Non-contentions hard fork so there will be two separate chains but the old chain will die immediately and the average person will not notice any changes or that there was a fork in the road. so ETH blockchain will be 99% same as before.
