Developers of Geth, one of the most popular clients of Ethereum, presented a new version of the software with the included code of the upcoming hard fork Constantinople.
Go-ethereum (Geth) v1.8.20 assumes that hardfork in the main Ethereum network will take place at block 7,080,000.
Consensus regarding the block number for activating hard forks was reached last week during a regular video conference of leading Ethereum developers. According to Afri Shedona, release manager of another popular client of the network Parity, a block of 7,080,000 will be mined between January 14 and 18, 2019.
At the same time, Ethereum Foundation’s head of security noted that the new version of the go-ethereum client would contain a kind of “emergency switch” that would postpone the upgrade if something went wrong.
Originally scheduled for November, the Constantinople contains a number of changes and code optimizations designed to ease the transition to the Proof-of-Stake algorithm. In particular, they include the transfer by 18 months of the so-called “bomb of complexity”, which contributes to timely upgrades, and also suggests a decrease in the reward to miners from 3 to 2 ETH for the mined block.
