法国一家区块链初创公司希望将区块链技术应用在时尚奢侈品行业,他们希望帮助奢侈品牌定制的手袋和昂贵手表创造独一无二的数字身份,而且已经创造了一个类似以太坊的区块链,通过使用共识机制将有权限要素和无权限要素结合起来,构成了一个全新的概念——“权威认证(proof-of-authority

Clique - proof-of-authority> 2How many seconds should blocks take?
对于本指南,我们使用的是私有的Proof-of-Authority网络。如果想创建这样一个网络,可以阅读我们以前的帖子。
Clique - proof-of-authority > 2 How many seconds should blocks take?
在这篇文章中,我决定分享我如何使用Geth的clique共识引擎设置一个Proof-of-Authority网络。 Clique - proof-of-authority > 2 How many seconds should blocks take?

The alternative proof-of-authority mechanism significantly reduces the delay of operations.
权威证明(PoA,Proof-of-Authority) 优点:节能、快速。 缺点:略为中心化;虽然可用于公有区块链,但是通常用于私有区块链和许可区块链。
