Good morning Ryan,

If I modify your Sentinel Chain open-source software so that it is honest for 999 sidechain blocks, then lies and says that the 1000th block is invalid even though it actually is, what happens?

Do mainchain nodes need to download the previous 999 sidechain blocks, run the sidechain rules on them, and then validate the 1000th sidechain block itself?

Regards,
