Bitcoin has been growing, since its inception in 2009, to gain a financial mainstream despite the constant fluctuations in its value. It is currently ranked as the most successful Crypto-Currency and decentralized payment system among the others. This success is due, to some extent, to its security, which depends mainly on the cutting-edge cryptographic innovations, such as the hashing functions, the elliptic curve digital signature (ECDSA), and the difficulty that regulates the mining process and allows the system to keep up with the increasing hash-rate. This paper provides an overview of Bitcoin difficulty and how it contributes to the security of this Crypto-Currency.
