500'000€ Prize for Compressing Human Knowledge

This privately run and funded contest offers a 500,000-euro prize for compressing human knowledge, with payment only if a solution reflects the contest's spirit. Decompressors that secretly receive outside information are forbidden, and claims must run on the organizers' machines within reasonable space and time limits. The smallest claimable prize is 5,000 euros, and payment cannot be legally enforced. The rules may change at any time, and the prize formula will be adapted after an award.
