Ethereum Constantinople Hard Fork to Come in Mid-January, Based on Dev’s New Agreement

Once activated, the upgrade is supposed to fundamentally change the Ethereum blockchain, with the synchronous nodes update to the entire system.

Launched on July 30, 2015, Ethereum is now the third biggest cryptocurrency by market cap at around $9.7 billion and is trading at $95.88 as of press time, according to data from CoinMarketCap.
