After the Ethereum sinked down to $116 on Bitstamp following the news of delay in the hard fork, Ethereum core developers have proposed activating Constantinople in late February. The launch is estimated to be around the February 26, 28.
The smart contract audit firm Chain Security elaborated a security vulnerability in one of five Ethereum Improvement Proposals. The proposal will be included in the hard fork, as it relates the data storage costs (on blockchain). Following this, the decision was formalised after the core developers’ conference call on Friday morning.
The call was also designated to ensure that test networks and private networks that have already implemented the full Constantinople upgrade can easily implement a fix without rolling back any blocks.
As a result of the vulnerability, Constantinople, now set for activation next month, will not feature inclusion of the buggy EIP, which will be tested and refashioned for inclusion in a subsequent hard fork.
“My suggestions is to define two hard forks, Constantinople as it is currently and the Constantinople fix up which just disables this feature…By having two forks everyone who actually upgraded can have a second fork to actually downgrade so to speak,” explained Péter Szilágyi, the core developer.
Matthias Egli – COO of ChainSecurity – highlighted that the issue was likely not picked up by core developers when running tests on the software given that the impact is rooted in smart contract development, not necessarily “[ethereum virtual machine] core” development.
