Those of you who know what public-key cryptography is may have already heard of ECC , ECDH or ECDSA . The first is an acronym for Elliptic Curve Cryptography, the others are names for algorithms based on it.
Could an IBM mainframe from the 1960s mine Bitcoin? The idea seemed crazy, so I decided to find out. I implemented the Bitcoin hash algorith...
In the previous post , we have seen how elliptic curves over the real numbers can be used to define a group. Specifically, we have defined a rule for point addition : given three aligned points, their sum is zero ($P + Q + R = 0$). We have derived a geometric method and an algebraic method for computing point…
A tale of differing visions
The responses of many to my post on Bitcoin reveal a powerful tendency to underestimate the ill-effects of deflation on a social economy. This tendency to underestimate deflation’s deleterious impact matters beyond debates on Bitcoin per se. For example, in Europe the incapacity of the European Central Bank (ECB) to…
