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. “

It is better for the Ethereum to be attacked now so that the vulnerability will be reparied when the price is low.
