[Security Alert] Consensus was reached with Ethereum developers, experts, and community members,
and a decision was made to temporarily postpone the upgrade.
According to the Ethereum Foundation, the cause of the postponement is the discovery of a vulnerability to “re-entrancy attacks.”
This was revealed through the point raised in a blog article titled
“Constantinople enables re-entrancy attacks.”
The major Ethereum (ETH) upgrade "Constantinople" was originally scheduled for November last year, but
its postponement was announced due to trouble during testing on the testnet “Ropsten.”
