...争取记账权，并获得相应的奖励，也可以将其看成是一个向记录着数字资产过往交易的账本中添加新交易的过程。这一过程属于资源密集型和困难型。 以比特币为例，在其系统中，每隔两周挖矿难度就会根据这期间开采出来的区块数量而进行调整，将出块时间维持在10分钟左右，以保证系统的平衡。而矿工想要争取到区块链的记账权，获得相应奖励，就需要不断提高自己的算力，也就是计算出正确哈希值的速度，这将消耗大量电力。 最初，每个用户都可以通过运行原始的比特币客户端，来使用CPU进行挖矿。然而，随着挖矿算力不断提升，CPU挖矿的时代已经成为过去式，随之而来的是ASIC矿机挖矿和大规模集群挖矿的时代。 当然，除了POW挖矿之外，以POS为共识机制的数字资产也同样需要挖矿。只是在 PoS机制中，增加货币供应的过程分为两个部分，交易所开发Q周顾问3II2325834一部分是根据用户持有货币的数量和时间派发利息；另一部分才是类似于POW的挖矿过程，它基于交易输入和其他一些固定数据计算哈希值，挖矿难度与交易输入的“币龄”成反比。 在POW挖矿的过程中，将消耗大量的能源，来进行哈希运算以保证工作量的公平；而POS挖矿则在一定程度上节省了能源，但其依然需要进行挖矿，在本质上并没有解决商业应用的痛点。 【Tel+86/电：I38-235I-5578】 【企鹅Q：3II-2325-834】 【地址：广东省深圳市龙华区民治大道展滔科技大厦A栋15楼 】 【】 交易所搭建,数字资产交易系统搭建，数字资产交易平台搭建，数字资产交易系统网站搭建，数字资产OTC交易平台搭建，数字资产抵押平台搭建,区块链场外OTC交易平台搭建,区块链技术运用搭建,多币种钱包搭建，数字资产场外C2C平台搭建，数字资产币币撮合交易网站搭建，币币撮合交易所搭建，企业内部直播聊...

(8)文章、话题详情，都用到了图文混排技术,使用WebView加载HTML代码,css控制样式 白天黑夜模式,js设置大图的点击时间，通过WebViewClient回调到页面。 (9后台Service控制电台、音乐的播放,电台使用API,MediaPlayer在线播放mp3。
