版本、投票比例、硬分叉版本投票比例限制。

隐含意思：这个版本有多少人投票，投票比例是多少，比例到达多少即代表分叉成功。

// this is work in progress
// hard forking is integrated deep within the the blockchain as almost anything can be replaced in DERO without disruption
const default_voting_window_size = 6000 // this many votes will counted
const default_vote_percent = 62         // 62 percent votes means the hard fork is locked in
