工作量证明机制是什么 工作量证明(Proof of Work,简称POW)是共识机制的一种,可简单理解为一份证明,证明你做过一定量的工作,即我通过查看工作结果就能知道你完成了指定量的工作。 比特币挖矿采用的就是工作量证明机制,比特币网络通过调节计算难度,保证每次竞争记账都需要全网矿工计算约10分钟,才能算出一个满足条件的结果。该结果即“区块头”里包含的随机数。 工作量证明是指,如果矿工找到了一个满足条件的结果,我们便可以认为全网矿工完成了指定难度系数的工作量。获得记账权的几率取决于矿工工作量占比全网的比例,如果占比30%,那么获得记账权的几率也是30%。所以提高工作量占比才能提高竞争力,才能获得更多新诞生的比特币!
