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 because of the 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 occasions per block. The consequence of that is that the community is significantly slowing down, however there’s NO consensus failure or reminiscence overload. We’ve got presently recognized a number of routes for a extra sustainable medium-term repair and have builders engaged on implementation.
It’s extremely reccomended to modify to Parity mining. Use these settings:
–cache-size-db 1024 –gas-floor-target 1000000 –gasprice 50000000000
