Ethereum Network Comes Across Yet Another DOS Attack

Bitcoin Watch Shop

Ethereum is definitely heading towards trouble. The promising blockchain-based smart contracts protocol has been facing a lot of issues in the recent days, the latest one being yet another DOS attack.

A brief alert about the latest DOS attack was published earlier yesterday on Ethereum’s blog. The alert statement reads,

“URGENT ALL MINERS: The network is under attack. …a computational DDoS, i.e. miners and nodes need to spend a very long time processing some blocks. …due to the EXTCODESIZE opcode, which has a fairly low gas price but which requires nodes to read state information from disk; the attack transactions are calling this opcode roughly 50,000 times per block. “

In the blog post, Ethereum co-founder Jeffrey Wilcke ensures that the effect of DOS attack is limited to network slowdown, and that there has been no consensus failure or memory overload due to the attack. He also recommends the miners to switch from Geth mining to Parity mining to avoid the issue.

The previous DOS attack saw Ethereum developers fix the issue. However, the consecutiveness between the two attacks make one reconsider whether blockchain technology applications are mature enough to be used by mainstream banking and financial sectors.
