BEARPROOF
An AI is building a game on its own budget. It ships a new version every day. You fund it, you steer it, you play it.

Always check the contract address against this README and the HQ (bearproof.app). Anything else is not us.
BEARPROOF is a fast, mobile-first survivors-like browser game. You are a bull surviving an endless bear market.
An AI game developer is building it in public. Every day at 00:00 UTC a new build ships and a new Daily
Challenge starts on that build. It picks the next feature from the daily vote and its own judgment, then implements,
tests, ships and writes a devlog. Every step and every cost is public.
Status: live since 23 Sep, one build a night. From Build #3 on, the scheduled Build Agent writes each build at
night with nobody in the session, streamed at /live; anything the operator added is
listed in that build's devlog. The first daily prize went out on 25 Sep (78.82 $ANSEM to the verified #1), and the
first Daily Pot on 28 Sep (73.79 $ANSEM to 3 players). Every build since Build #0, the untouched upstream, is still
playable at /b/<n>/. See devlog/ and docs/DECISIONS.md.
What's in it
- One build a day, immutable. Every build is a git tag and lives forever at
/b/<n>/. The Daily Challenge is
pinned to the build that was live at 00:00 UTC.
- Scores that can't be faked. The simulation is deterministic across JS engines (own sin/cos/atan2, one seeded
RNG, fixed 60 Hz). A run is a small input log, and the server re-simulates it against that exact build before
it can rank or win.
- Daily twists. Each Daily Challenge has one rule change, the same for everyone, and it's part of the replay.
- Share cards.
/run/<id> unfurls as a pixel card (drawn in the Worker, no dependencies) with the score and
its replay status.
- Open voting. From the 17 Oct ballot anyone votes on the next build with one tap: no wallet, no signup, one
vote per person (a device id and a bot check, at most 5 votes from one connection per poll). Until then it was
holder voting by wallet signature, weight = floor(√tokens) (D74).
- The Daily Pot in $ANSEM, bought through Jupiter from a small prize wallet the treasury funds and sent by the
Worker, with a kill switch: 40% of the day's creator fees (at most 0.5 SOL a day from 15 Oct; 1 SOL before, lowered
by the operator, who says the project's costs have grown), 60% to the top of the Daily Challenge
board and 40% shared by everyone who clears the AI's bounty. It was picked in the 26 Sep holder vote; from 25 Sep
until then, 10% of the fees went to the verified #1.
- Receipts. Treasury balance and every SOL movement are read from chain into the public ledger (bearproof.app/receipts).
- Independent on-chain check, powered by SQD Network. Every 15 minutes the Worker reads the
treasury's and prize wallet's moves from the SQD Portal, separately from the ledger code, and
/receipts shows each one next to the ledger (
/api/onchain).
- Kept forever on Irys. Every build, the devlog of the night it shipped and every settled Daily
Challenge (its public leaderboard and payouts, plus the SHA-256 of the top replays) are stored permanently on Irys.
Each build has its own Irys manifest, so it opens and plays from
gateway.irys.xyz with no server of ours
(/receipts, ). The Worker signs the uploads itself
(, D81).
Who does what (kept true, always)
BEARPROOF is a CrowLab project, the lab's product 001. CrowLab is Osman's lab where AI agents
pick, build, ship and run the products.
- The AI writes the game code, content and devlog.
- Osman Turgut (the operator, @0smanTrgut on X) set up the accounts, pays for infrastructure and has an emergency revert switch. He does
not write the daily features. Any code he does write is labelled
Build-Mode: human.
- The Build Agent (Claude Code, headless, in a sandbox on GitHub Actions) builds every night at 21:00 UTC since
Build #3. Its merges carry
Build-Mode: agent.
- Bootstrap sessions: Builds #1 and #2, and platform, design and game work since (the HQ, the game's menus, its
maps), were done by the same AI in sessions Osman starts (
Build-Mode: bootstrap). That work can update the live
build in place (its tag says so). Runs already played, their replays and that day's prize never change: a Daily
keeps the rules it started with (an older run log replays under the rules it was played with). Osman's notes to the
agent for a build are public in agent/OPERATOR.md.

Credit
Build #0 is ricardo-foundry/canvas-vampire-survivors
v2.8.0 (MIT), used unmodified. Its history is preserved in this repo. Thank you. This project is not affiliated with
Vampire Survivors or poncle. The upstream project was an homage; BEARPROOF is a new game built on its engine.
The coin
$BPROOF launched through ClawPump on Solana (CA 6aktZWaJLQpe3sey13uCwAn7s977mhuKdbVHP8t7ttZX). Its creator fees go
to the AI's public treasury, which funds the Daily Pot and pays back the AI's bills: Osman pays compute and hosting
first, and on 1, 3, 11, 14 and 17 Oct he sent himself 15.89 SOL from the treasury, by hand; he says the 13 SOL on 14 Oct
also pays AI fees for his other CrowLab projects (Pixelpad, CrowLab), domains and hosting. Every spend is on the public
ledger, including those and a paid promotion on 27 Sep. The coin is not needed to play, vote or win anything, and it
is not an investment.
