Hah. Here&#x27;s a diagram from a recent isogeny paper:<p><a href="https:&#x2F;&#x2F;s-media-cache-ak0.pinimg.com&#x2F;736x&#x2F;0f&#x2F;92&#x2F;7f&#x2F;0f927f795f3cfa199d474894fa781c74.jpg" rel="nofollow">https:&#x2F;&#x2F;s-media-cache-ak0.pinimg.com&#x2F;736x&#x2F;0f&#x2F;92&#x2F;7f&#x2F;0f927f795...</a><p>Isogenies are mappings between curves. So maybe one way to start getting your head around isogeny crypto is that you&#x27;re dealing in higher-order curve structures.
