//首先在nep5基础上将账户分为两个部分
//一个部分是saving
//saving 有一个产生块的标记
//一个部分是cash
//当你收到一笔转账，他算在cash里面
//当你花费一笔钱，先扣cash，扣完再扣saving
//余额是saving 和 cash 的总和
//cash 如何转换为为saving
//通过claim 指令
//claim指令 将领奖并且把所有的余额转换为saving，产生块标记为当前块
//*claim指令
//claim指令取得已经公布的奖励，仅有自己的saving的block <奖励的startblock 才可以领奖
//领奖后全部资产+领到的资产变成saving状态
//消耗池
//所有花费掉的资产进入消耗池，等候公布奖励
//公布奖励
//将现有奖励从消耗池中取出，变成一个奖励，奖励规定只有savingblock <startblock 才可以领取。
//根据 消耗池数量/总发行数量 确定一个领奖比例。
//将同时保持五个公布奖励。
//当公布第六个奖励时，第一个奖励被删除，并将他的余额丢入消耗池
//*检查奖励指令
//程序约定好公布奖励的block间隔，当有人检查奖励并且奖励的block间隔已经大于等于程序设置，则公布奖励。
//用户可以用检查奖励指令获知最近的五个奖励，以此可以推算，如果领奖自己可以获取多少收益。
//增加两条指令
//checkpool*检查奖励
//claim*领取奖励
//可循环分配资产
//最终确定加四个接口（暂定名Nep5.1）
//检查奖励，只读（everyone）
