Oh no, the SEC got their mining definition from the bargain bin

1. Miners don’t solve complex equations: they're repeatedly hashing a block header using the SHA-256 algorithm until a valid hash is found

2. Not cryptographic puzzles: it's closer to a brute-force search for a hash that meets a specific difficulty target

3. The process is trial & error: a game of luck & computational power

We're getting there, but more education is needed
