What We're Building

In this section, we'll create a precompile for the MD5 hash function. By utilizing the existing Go library for this hash function, we can avoid reimplementing the algorithm in Solidity and take advantage of Go's superior efficiency.

Reference Implementation

To aid your understanding of building precompiles, we will compare each step with a reference example: a precompile for the SHA256 hash function. Both precompiles are quite similar, featuring a single function that returns the hashed value.
