URGENT ALL MINERS: The community is underneath assault. The assault is a computational DDoS, ie. miners and nodes have to spend a really very long time processing some blocks. That is as a result of EXTCODESIZE opcode, which has a reasonably low gasprice however which requires nodes to learn state info from disk; the assault transactions are calling this opcode roughly 50,000 instances per block. The consequence of that is that the community is vastly slowing down, however there may be NO consensus failure or reminiscence overload. We’ve got at present recognized a number of routes for a extra sustainable medium-term repair and have builders engaged on implementation.
It’s extremely reccomended to change to Parity mining. Use these settings:
–cache-size-db 1024 –gas-floor-target 1000000 –gasprice 50000000000

Should you proceed to make use of geth, use the next settings:
–cache 1024 –targetgaslimit 1000000 –gasprice 50000000000
