📝 Original message:Hi Bitcoin Developers,

There were some disagreements with speedy trial activation method recently and BIP 8 became controversial because of LOT earlier. I have tried to solve these two problems after reading some arguments for/against different activation methods by removing LOT from BIP 8 and calculating MUST_SIGNAL state based on threshold reached.

BIP draft with no code and some changes in BIP 8: https://gist.github.com/1440000bytes/5e58cad7ba9d9c1a7000d304920fe6f1

State transitions diagram:

This proposal removes lockinontimeout flag, activation never fails although MUST_SIGNAL can be longer if miners signaling does not reach the threshold. Longer period for MUST_SIGNAL state is useful for coordination if LOCKED_IN was not reached.

MUST_SIGNAL = ((100-t)/10)*2016 blocks, where t is threshold reached and blocks that fail to signal in MUST_SIGNAL phase are invalid.

Example:

- This activation method is used for a soft fork
- Only 60% miners signaled readiness and timeout height was reached
- MUST_SIGNAL phase starts and will last for 4*2016 blocks
- LOCKED_IN and ACTIVE states remain same as BIP 8
- Soft fork is activated with a delay of 2 months
