It became known that the update Ethereum Constantinople Hard Fork, which was to begin on January 16, is postponed.
According to the official blog of Ethereum, the delay is caused by a potential security vulnerability identified by the audit company ChainSecurity on January 15th. A security bug can potentially make some Ethereum smart contracts vulnerable to a so-called “re-attack”, allowing an attacker to steal the ETH of other investors.
But it is worth noting that no Ethereum smart contracts are currently vulnerable. In fact, the BlockSecurity check of blockchain Ethereum did not find any contracts that would be vulnerable even if the update took place, but the Ethereum developers decided to reduce the risk by postponing the update.
Ethereum developer Hudson Jameson wrote the following on a blog:
Since the risk is not zero, and the amount of time required to confidently determine the risk, more than the time available before the planned update in Constantinople, it was decided to postpone the fork.
At the moment, there is no new update date for Ethereum. This is not the first time it has been postponed, because the update was originally planned to launch in November 2018, but it was postponed due to a number of errors.
