漫话比特币

in #bitcoin6 years ago

比特币挖矿是干什么?要挖掘机吗?

挖矿是猜数字游戏,实质相当于银行的记账与清算当然还有其他功能。
通过激励人们通过工作获取比特币记账权从而比特币奖励

竞争代替了冲突,

币的发行有规则每四年减半

记账员的激励矿工得到增发币和交易费用。

实现坚不可摧的账本,想篡改账本要把历史上的挖矿重来一遍,这是任何人、组织、国家无法完成的任务。难度会随挖矿参与者计算能力多少自动调节控制发行量。 早在2013年7月,比特币全网算力已经达到世界前500强超级计算机算力之和的20倍

矿池无法控制矿工,矿工利益与矿池不一致

电力(而且大部分情况是弃电)转变为数字黄金。
