As you probably know, today ETH should have been implemented a new hardfork, aimed at decreasing transaction costs and increasing transaction throughput. Due to a bug discovered and disclosed a few hours before the event, the hardfork, dubbed "Constantinopole" has been postponed.

The vulnerability, a design hole called "reentrancy attack", may allow an attacker, under certain circumstances, to interact with smart contracts designed in a specific way. According to the blog post describing it, exchanges may be vulnerable to this.

ETH core developers confirmed the vulnerability and started to work on a fix, which may be announced this Friday. Until then, Constantinopole will not be rolled out.
