What's a URSF?
Those that run the UASF will build a chain, from a predefined activation height, that doesn't contain any large op_returns
What exactly does the URSF do? It requires that the block at...
That’s one way to do it, but would be pretty ugly.
It would be better IMO to activate using BIP8 with LOT=true. That way miners will be required to signal readiness for soft fork activation before some deadline. Blocks that don’t signal would then start being rejected. (Assuming @Luke Dashjr @Luke Dashjr will be involved with this UASF I assume this is what he’ll prefer as well.)
The URSF client should then use these same signals in the opposite way; it should start *rejecting* blocks that signal readiness.
This way you get a relatively clean split at a (more or less) predictable time.
