Double Signing attack test
Since I can't find more information about how double signing will harm the network and what defensive mechanism network will have against double signing, I am going to perform a 30 minutes double signing attack on test net. Double signing could happen due to honest witness mis-configuring node, witness server compromised by evil third party or corrupted witness.
I have 3 witness accounts voted in that I can coordinate, I am going to try double signing from 1, 2, 3 witnesses using 2 separate servers (US, Asia).
Here is the plan:
The attack will last for 30 minutes, 3 phases, each will last for 10 minutes.
phase I (0-10min): 1 double signing witness (boombastic)
phase II (10-20min): 2 double signing witness (boombastic and mr.agsexplorer)
phase III (20-30min): 3 double signing witness (boombastic and mr.agsexplorer and mrs.agsexplorer)
end (30min): stop double signing
Double signing will cause fork, I want to see after all this mess, if network can recover, and I will do some transactions during the attack and see how it's gonna affect normal user operations. If you are here, you can perform normal operation and report back after the attack is finished.
bytemaster, if you see this, please do not vote out these double signing witness just yet. In real world, if some witness starts double signing, voters might not react that quickly, network should survive on its own for at least 30 minutes.
The attack will start at today 2015-09-23 18:00 (UTC), which is 20 mintues from now
