As I understand Andrew Chow has a patchset for height based activation of Speedy Trial, so that it would be great if people could review that to help increase the review-cycles. Personally I also somewhat prefer block-height based activation, and for myself it seems like a mild step backwards to

I'm pretty sure that the question of "is signalling still possible by the time enough miners have upgraded and are ready to start signalling?" Strongly benefits from a guaranteed number of signaling periods that height based activation offers. Especially for the short activation period of Speedy

I found the "50% chance of activating" a bit confusing of a watermark, so I asked AJ if he didn't mind producing and tabulating the 10% chance, 50% chance, and 90% chance to show the sharpness of the bounds better. Each category below shows the single-shot and repeated trial odds for the range of

I'd like to pre-register a comment that I don't think signet should be a consideration for MTP vs height, since taproot is already activated on signet, and there's no indication that ST will be used in the future (we should continue our search for the ideal activation method) Robert Spigler

So the only thing that seemed clear, using height as per bip8, it's not clear anymore. And, as usual, we're not talking about activation in general but about taproot activation, segwit activation... I won't make it to the meeting because I don't think I have much more to contribute that I haven't
