The Ethereum Foundation has announced that 2019 has identified a vulnerability in the system that could cripple Ethereum’s core network. According to the foundation, these problems have been fixed with the Berlin update.
to the the report Calling the vulnerability “catastrophic”, Ethereum Foundation Coin Telegraph said in a post that the network had existed since the launch of the Berlin Hard Fork.
According to the Ethereum Foundation, the Berlin Update enabled the network to overcome this major health threat.
The report states that the problem was once mentioned unintentionally and erroneously and has remained a mystery ever since. Following the launch of the Berlin Update, Ethereum developers concluded that the threat was small enough to be written about. In the Ethereum report we read:
It is important for the community to be given the opportunity to understand the reasons behind the changes that are adversely affecting their user experience.
The Ethereum Foundation refers to the increase in transaction fees and the restriction of return on investment as these bad user experiences.
The Ethereum Foundation also mentions the Merkel Patricia tree used in the Ethereum system. This system conceptually puts Ethereum transactions side by side. With the growth of the Ethereum network, fees were increased to combat Distributed Service Prohibition (DDoS) attacks. One of these plans was the Ethereum 1884 improvement plan, which had many ramifications.
In 2019, Hubert Ritzdorf, Matthias Egli and Daniel Perez, members of the Ethereum Security Research Team, sought to exploit the vulnerability created after the updates. This was done using constant requests for Merkel tree information and could increase block generation time by up to one minute. Shortly afterwards, a report was released indicating that as Ethereum’s network grew, the delay in block generation could increase, and could be used as a potential tool for Didas attacks.
After several improvement plans that were not accepted by the Ethereum community in 2020, Vitalik Butrin and Martin Swende presented the 2929 and 2930 improvement plans. The plan increased fees for specific transactions to prevent Didas attacks. The improvement plans were implemented on the network during the Berlin Update last month. According to reports, these plans reduce the likelihood of such attacks by up to 50%.
Ethereum is not the only network that takes such a liberal approach to these vulnerabilities.
In September 2020, Braydond Fuller and Javed Khan published a study on the high vulnerability of bitcoin network solutions such as Lightning. Although it was estimated that 50% of ninety bitcoins were exposed to such attacks, the authors did not identify any such attacks.
