The canonical archive of what bitcoin builders have tried, plus the forward-looking view of might still be worth exploring. So you can stop searching and start creating.

For motivated bitcoin builders picking their next project. For strategists mapping the arc. For researchers tracking who built what when.

The bitcoin ecosystem's open problems are visible only to people already deep inside it. New builders show up ready to ship and can't see what needs building. Returning builders waste cycles on paths the last cohort already exhausted. Strategists trying to read the arc are stuck stitching it together from twelve dead Devpost galleries.

Bitcoin Products collapses your search cost from "scroll twelve dead galleries" to "open one page, filter, decide."

Two surfaces over one data layer (three datasets):

• IDEAS.TXT: 35 forward-looking ideas, each anchored in a decade of past attempts
• PRODUCTS.TXT: 76 hackathon products read end to end plus 492 more indexed (filter UI ships next)
• SOURCES (queued): 118 hackathons indexed back to 2012, each as its own canonical entry with winners, organizers, sponsors, prize pools, and dates

Hackathons compound. Take bitcoin-as-game-rail: Bitcoin Pong (2012), Bitcoin Mages (2012), SuperMarioBits (2015), Lightning Roulette (2024), BitDoom (2025), and Space Shooter (2025). Six teams across thirteen years, each with a different angle on the same idea. That pattern is invisible when you only look at one product at a time. The archive makes it visible.

Two more ideas have drawn similar arcs across 13+ years: pay-per-use content monetization, small-merchant bitcoin acceptance. Each new generation of builders takes a fresh swing.

How you can help:

• Review the masterlist: confirm scope on rows tagged unclear, or write up a deep entry for a bitcoin-tagged breadth row.
• Submit a hackathon I missed.
• Send a correction (the project will require many).

Schema is in the README; PRs welcome.
