The Ethereum hard fork network, Constantinople, will occur on block 7,080,000 from January 14-18, 2019.
About Ethereum fork
Initially the fork was planned for November 2018, but it had to be postponed due to the unsuccessful launch of the test network in October. During 2018, the ETH rate dropped from $ 1,400 to $ 100, and companies using Ethereum technology began to face increasing pressure from regulators. January 2019 can hardly be called the ideal time for the fork, but the developers have no choice because of the “complexity bomb”.
What is a Ethereum complexity bomb
The complexity bomb is built into the Ethereum code in order to make the blocks much slower after passing a certain point beyond which the “Ice Age” begins, during which the production of new blocks will be stopped. Because of the bomb, developers periodically have to make forklifts of the network, as well as update the technological base of Ethereum. Constantinople will not eliminate the bomb of complexity, but only postpone its “detonation” for 18 months.
