Ethereum’s developers have decided to postponed the network’s much-anticipated hard fork after a smart contract auditor flagged a potential vulnerability in the upgrade.
ChainSecurity notes that “as an unwanted side effect, this enables reentrancy attacks” for “certain Solidity smart contracts.”
The developers have responded by announcing – via the official Ethereum Reddit page and Twitter
[SECURITY ALERT] #Constantinople upgrade is temporarily postponed out of caution following a consensus decision by #Ethereum developers, security professionals and other community members. (Via Ethereum’s Twitter)
