secp256k1 is the elliptic curve used in Bitcoin’s public key cryptography. It is defined by the equation y^2 = x^3 + 7 and is based on the finite field mathematics. The “secp” in secp256k1 stands for “Standards for Efficient Cryptography” and “256” refers to the curve’s bit length. The “k1” indicates that it is the first elliptic curve proposed by Koblitz in 2000. It is widely used for generating Bitcoin addresses and performing cryptographic operations in the Bitcoin network.
secp--Standards for Efficient Cryptography(Prime field)
256--curve’s bit length
k1--it is the first elliptic curve proposed by Koblitz in 2000.
