How to Measure Support For Change

Miners can start signalling (voting) for SegWit after the first difficulty retarget after November 15th.


Mining difficulty is retargeted to maintain 10 min blocks:

At each retarget, support for segwit is measured based on previous signalling in previous 2016 blocks.
