Q: Elliptic Curve how to calculate y value

John PhamI have been reading the book Mastering Bitcoin written by Andreas. It was the process of compressing public keys that hurt my mind. Specifically, a public key after being generated from a private key fundamentally comprises the resulting coordination of x and y. The book said that since y value c...

Q: Is it possible to compute the y-coordinate of a point on SECP256K1, given only the x-coordinate

aafuleiGiven an x-coordiante of a point on the SECP256K1 curve, is it possible to calculate the corresponding y-coorindate? (Assuming the point is a verifying public key that complies with the Bitcoin standards.) I am new to the cryptographic realm so please forgive me if the question is naive. From wha...
