# '''startheight''' should be set to some block height in the future, approximately 30 days (or 4320 blocks) after a software release date including the soft fork. This allows for some release delays, while preventing triggers as a result of parties running pre-release software, and ensures a reasonable number of full nodes have upgraded prior to activation. It should be rounded up to the next height which begins a retarget period for simplicity.
# '''timeoutheight''' should be 1 year, or 52416 blocks (26 retarget intervals) after '''startheight'''.
# '''threshold''' should be 1916 blocks (95% of 2016), or 1512 (75%) for testnet.
