Developers confirm that Ethereum will go through two hard forks this week

• The developers of Ethereum have confirmed that they will go through two hard forks – Constantinople and St. Petersburg – this week.
• Constantinople was delayed last month because of security vulnerability issues.

The developers of Ethereum have confirmed that the two hard forks, Constantinople and St. Petersburg, are scheduled to take place this week. According to their announcement:

“The Ethereum network will be undergoing a scheduled upgrade at block number 7,280,000, which is predicted to occur on Thursday, February 28, 2019. The exact date is subject to change depending on block times between now and then and could be activated 1-2 days before or after.”

Constantinople is one of the most anticipated hard forks of Ethereum which will implement five different Ethereum Improvement Proposals (EIPs). However, this upgrade was delayed after a security vulnerability was discovered. Joanes Espanol, CTO of blockchain analytics company Amberdata, explained the vulnerability to CoinDesk:

“Imagine that my contract has a function which makes a call to another contract”¦ If I’m a hacker and I’m able to trigger function a while the previous function was still executing, I might be able to withdraw funds.”
