Despite Hard Fork: Ethereum Blockchain still under attack

Even though yesterday’s Ethereum Hard Fork went according to plan, the Blockchain attacks continue as usual.

This time the Ethereum Blockchain was due for hard forking last Tuesday because the Blocckhain has been the target of a sustained DoS attack for a month now. After weeks full of problems with transaction processing and generating new blocks, the development team behind Ethereum has decided to change some network features. Miner and users promptly followed up and updated their clients (also known as the „hard fork“).

The smooth transition to a new transaction record was also what the developers expected, because this time the Hard Fork was just a technical change – unlike the Hard Fork to solve the DAO debacle. Here the blockchain has been rewritten.

But the developers didn’t expect the Bitcoin profit

The attackers seem to have put on another gear. They are using a probably unpredictable Bitcoin profit, which could only be fixed now.

According to Hudson Jamson of the Bitcoin profit Foundation, the developers are currently working on a solution: „We are currently working on a client update to mitigate the problem until the second hard fork. Second Hard Fork follows. Since the attackers used different attack vectors, the developers had planned two consecutive hard forks from the beginning.

The first fork served to correct the „gas price“, since the attacker or attackers used the incorrect calculation of the gas price to flood the block chain with transactions and contracts, forcing the individual nodes with CPU- or memory-heavy operations to their knees. The second fork is designed to eliminate all „spam accounts“ created by the attackers. The attackers currently create so many accounts that they clog up the entire network and cannot be dismantled.

What happens next to the Bitcoin profit?

Even after the second hard fork you are not sure how to proceed like this: Maybe the attackers will then find another gap. The wave of attacks has sparked a big discussion about how the Bitcoin profit developers can protect the network from such attacks in the short, medium and long term.

Some say the attacks are an inevitable consequence of how the Ethereum network is built – more platform functionality, unlike other blockchain networks, means a larger attack surface at the same time.

After the new wave of attacks, BitGo developer Jameson Lopp wondered how many hard forks the network would need to finally plug all the holes.

„The real problem is that there is not enough testing,“ says IBM blockchain specialist Martin Hagelstrom. „Even if the developers talk about the problems, they don’t seem to be fully aware that there is 1 billion US dollars in their network.

Other observers, however, were optimistic, including Marco Streng, CEO of Genesis Mining. He says he is impressed by what the Ethereum network has been through in recent months and how they have mastered it:

„All this is a clear sign that Ethereum will come out of this stronger than they have ever been before“.

Author’s opinion (Mark): Yes, the technology isn’t yet secure against every conceivable type of attack, and the development team behind Ethereum is trying to plug the holes. First the DAO disaster, which of course wasn’t the Ethereum Enwtickler’s fault alone, and then the ongoing DoS attack that brings the whole network to its knees. I agree with Jameson Lopp to a certain extent. The technology has obviously not been sufficiently tested for such a big undertaking. Everyone here wants to be the first and bring the best solutions onto the market. Only these should then be thought through accordingly. We’re not talking about an apple pie that can be forged here and there, but about 1 billion US dollars.“
