To generate the md5 hash "1a4f182a05210f17ed1397abf900d3ee" I've used three common lowercase English words (rank ≤1000), one username of some Manifold user, and their userId. For example, the following string matches my constraints: "if MayMeta then use saz6JvvXt2Woe0iXUTBz3KqCQ863", but produces a wrong md5 hash: "51fd8fbb0e0a26e3461b0f7c4bcc0095". The relative order of the 3 words, the username, and the userId is not defined. The string matches the following regular expression: ^\w+(?: \w+){4}$

Whoever provides a justified upper bound on how fast the "1a4f182a05210f17ed1397abf900d3ee" md5 hash can be cracked on a modern CPU using the constraints I provided will receive a Ṁ50 manalink from me. Bonus Ṁ50 if they list reasonable assumptions that can lower this upper bound at least 1000-fold.

Whoever first cracks this md5 hash and posts the source string in the comments will receive a Ṁ500 manalink from me.

If this hash is cracked before August 31st, 2023, 23:59:59 UTC then this market will resolve YES, otherwise NO.

* This is a puzzle market, created to raise awareness of md5 hash cracking techniques. I am not sharing the source string with anyone, and it doesn't exist anywhere on the internet. I myself will not bet on this market.
