this should work. nice and simple and pleases Chinese miners w/o giving miners in general any votes:
https://www.reddit.com/r/Bitcoin/comments/39ziy6/eli5_what_will_happen_if_there_is_a_hard_fork/cs7xe9oIf 75% of hashing power is producing up-version blocks
AND after some brave miner decides to actually produce a >1MB block.
8MB max block size (chinese miners were unhappy with 20 for not-entirely-clear reasons)
Earliest fork date 11 Jan 2016 (miners and others want sooner rather than later)
Activation when 750 of last 1,000 blocks are up-version (version 0x20000004 to be compatible with sipa's new versioning bits scheme)
2 week 'grace period' after 75% threshold reached before first >1MB block allowed to be mined
8MB cap doubles every two years (so 16MB in 2018, etc: unless there is a soft fork before then because 16MB is too much)
Not sure why limiting the date is necessary. I feel like we should be able to pull this off sooner, especially if we are backed into a corner by some kind of big rally.
