This success rate is 1/(2^n), and the cost of successful mining increases with the n-index. The best way to find x is to try-error, that is, randomly generate x to calculate f(x) until the result meets the requirements. I think that after a dozen years, maybe sha256 will become unsafe.įor a safe hash function, it is known that the first n bits of f(x) are 0. It is okay to choose MD5 for more than ten years.
Sha256 was chosen because it is a well-recognized hash function recognized at this stage. The song in the background is Can You Feel My Heart by Bring Me the.

In principle, f(x) must be irreversible, and the output is uniform. This is to prove a proof of workload (power consumption), making it difficult to find a proof, to consume a lot of computing resources, but verifying its should be easy.įor Bitcoin mining, the sign of successful mining is to find a string of numbers x such that the first n (binary) bits of f(x) are zero. SHA-256 is used in two parts of the Blockchain network: generate new bitcoin address and the "proof of work" algorithm used in mining. SHA-256 is designed by NSA, it's currently most used Hash algorithm.
