Bitcoin uses a specific elliptic curve and set of mathematical
constants, as defined in a standard called +secp256k1+, established by
the National Institute of Standards and Technology (NIST). The
+secp256k1+ curve is defined by the following function, which produces

As we saw in the section <<public_key_derivation>>, a public key is a point [.keep-together]#(x, y)# on an
elliptic curve. Because the curve expresses a mathematical function, a
elliptic curve. Because the curve expresses a mathematical mapping, a
point on the curve represents a solution to the equation and, therefore,
if we know the _x_ coordinate, we can calculate the _y_ coordinate by
solving the equation [.keep-together]#y^2^ mod p = (x^3^ + 7) mod p.# That allows us to
