# Generator Point

The generator point, known as *G*, is a defined point on Bitcoin’s elliptic curve, secp256k1, and has x and y coordinates. In order to generate a public key, a user multiplies their private key *sk * G = P*, where *P* is the public key.

While a private key is a large number, a public key is a point with x and y coordinates. Likewise, *G* is itself a valid public key.

Like most public keys, the coordinates of the Generator Point are extremely large. Encoded in SEC format, the Generator Point can be written as 0279be667ef9dcbbac55a06295ce870b07029bfcdb2dce28d959f2815b16f81798.
