Just days before the launch of EOS mainnet scheduled for June 1 researchers found critical vulnerabilities in the network’s blockchain.

Through the vulnerability intruders can execute their own code on the network nodes and take control of them.

According to the company that found the problem EOS will not launch its mainnet until the vulnerability is fixed.

Surely enough the news has negatively affected the price of EOS that tanked 10%.
