The Ethereum network is currently undergoing a DoS attack


Posted by Jeffrey Wilcke on September 22nd, 2016.

URGENT ALL MINERS: The network is under attack. The attack is a computational DDoS, ie. miners and nodes need to spend a very long time processing some blocks. This is due to the EXTCODESIZE opcode, which has a fairly low gasprice but which requires nodes to read state information from disk; the attack transactions are calling this opcode roughly 50,000 times per block. The consequence of this is that the network is greatly slowing down, but there is NO consensus failure or memory overload. We have currently identified several routes for a more sustainable medium-term fix and have developers working on implementation.


It is highly reccomended to switch to Parity mining. Use these settings:


--cache-size-db 1024 --gas-floor-target 1000000 --gasprice 50000000000

Parity mining guides:


If you continue to use geth, use the following settings:

如果你想继续使用geth, 请使用以下配置:

–cache 1024 –targetgaslimit 1000000 –gasprice 50000000000
