 # Changing hardLimit is accomplished by encoding a proposed value within a block's coinbase scriptSig.

+## Absent/invalid votes are counted as votes for the current hardLimit. Votes below minimum cap (1M) are counted as 1M votes.  Votes above the maximum cap (32M) are counted as 32M votes.
 ## A new hardLimit is calculated at each difficult adjustment period (2016 blocks), and applies to the next 2016 blocks.
 ## Calculate hardLimit by examining the coinbase scriptSig votes of the previous 12,000 blocks, and taking the 20th percentile.
 ## A new hardLimit may not increase or decrease by more than 1.2x beyond the prior hardLimit.
