For a long while, I&#x27;ve been thinking of crowdfunding bounties for solving socially valuable science and engineering problems.<p>I&#x27;ve always been inspired by examples of this through history including:<p>- Longitude Rewards (17th century): https:&#x2F;&#x2F;en.wikipedia.org&#x2F;wiki&#x2F;Longitude_rewards<p>- Orteig Prize for Trans-Atlantic Flight (1920s): https:&#x2F;&#x2F;en.wikipedia.org&#x2F;wiki&#x2F;Orteig_Prize<p>- Fermat&#x27;s Last Theorem (1800s&#x2F;1908): https:&#x2F;&#x2F;en.wikipedia.org&#x2F;wiki&#x2F;Fermat%27s_Last_Theorem#Monetary_prizes<p>- Ansari X Prize (1996): https:&#x2F;&#x2F;en.wikipedia.org&#x2F;wiki&#x2F;Ansari_X_Prize<p>- DARPA Grand Challenge (2000s): https:&#x2F;&#x2F;en.wikipedia.org&#x2F;wiki&#x2F;DARPA_Grand_Challenge<p>What specific problems would you want to donate a few dollars to see solved and that will work with prize amounts in the range $1k-$500k? What referees would you recommend to determine if the problem is &quot;solved&quot;?
Ask HN: What scientific/technical bounties with social impact would you support?
