Top Stories This WeekEthereum’s Constantinople Hard Fork Delayed Until February After Vulnerability Found
Ethereum’s (ETH) Constantinople hard fork has been delayed until late February after smart contract audit firm ChainSecurity found a security vulnerability allowing a reentrancy attack. The security bug found would potentially let an attacker steal crypto from a smart contract on the network while requesting funds from it repeatedly while feeding it false data. In the aftermath of the discovery, Ethereum developers said that the activation would instead take place at block number 7,280.000, which is expected to be mined on Feb. 27, 2019, instead of in January. Before the bug was found, an Ethereum developer had said that the hard fork would be the least eventful in the history of Ethereum.
