I’ll aim to fire this off at around 1300 UTC, so ~8 hours away from now.
Plan is:
- mine a few normal blocks with nTime in the future so that inquisition miners defer creating new blocks and engaging in a race with the attack blocks
- mine the six attack blocks in a row, allowing them to propagate
- call invalidateblock on the first attack block, and restart my inquisition miner to eventually produce a more-work chain than the attack blocks
I expect mining the attack blocks will take ~10 minutes, and presumably propagation across the signet network will be somewhat slow (due to no compact block benefit, slow validation, and inquisition 29.2 nodes rejecting the block). There’s also a chance the network will partition somewhat, with inquisition 29.2 nodes disconnecting from peers that advertise child blocks built on the earlier attack blocks that inq nodes have already rejected.
Presumably it will take about an hour for the attack blocks to be reorged out (ie, for the inquistion miners to mine 7 blocks).
