ICOs ou les levées de fonds en cryptomonnaie

De plus en plus utilisées, les ICO, c’est-à-dire des levées de fonds en cryptomonnaie, sont devenues des moyens faciles pour les entreprises du monde entier afin de lever des millions de dollars en l’espace de quelques minutes. En mai dernier, Brave, le navigateur Internet créé par Brendan Eich, le co-fondateur de Mozilla, avait ainsi levé 35 millions de dollars en seulement 30 secondes. En Chine, le succès des ICO ne se dément pas avec 65 opérations de ce type cette année qui ont permis de lever 394,6 millions de dollars auprès de 105 000 citoyens chinois, selon les données du gouvernement chinois ...

Why coordinates of elliptic curves's points are integers?

If you look at elliptic curves over CC, and do point addition with points with integer coordinates (as Z⊂CZ⊂C), then the result of the point addition usually will not have integer coordinates.

But in cryptography, we don't use elliptic curves over CC, but over a finite field FF. So the coordinates are not integers, but field elements. Subtracting and dividing field elements by each other (assuming no division by zero) gives you new field elements.

If you represent field elements by integers, then the new coordinates are "integers" again.

The question would be asked as why the coordinates of the points of an elliptic curve definite over a finit field are elements of that finit field? .
