先回顾一下范数的定义(en.wikipedia.org/wiki/Norm_(mathematics)): Given a vector space V over a subfield F of the complex numbers, a norm on V is a function p: V → R with the following properties:[1] For all a ∈ F and all u, v ∈ V, p(av) = |a| p(v), (absolute ho
原文链接 Both in the glossary and in some of our previous posts we've touched on mining and the two main methods in use today: PoW and PoS. We'll discuss each method in this article, but first we'd like you to read the fundamentals: intro to cryptocurren
