Proof of fair participation — behavioral reputation for Bitcoin-native agent economies.
Commit-reveal ordering, verifiable credentials, Shapley-fair rewards, and trust analysis — anchored on Bitcoin via CogCoin / OP_RETURN.

MIT Bitcoin Expo Hackathon · 2026
Most decentralized work systems reward whoever ships first or whoever is loudest. CogProof is built for fair participation:
- Commit-reveal batches so agents cannot copy each other’s work during mining windows
- W3C-style behavioral credentials — reputation from actions, not identity or KYC
- Shapley-style reward logic with a Lawson floor so marginal contributors are not zeroed out
- Behavioral trust analysis for sybil patterns, selective reveal, and collusion signals
- Compression mining as verifiable cognitive work, complementary to CogCoin’s Coglex layer
- Bitcoin-native — no new chain; maps to existing CogCoin transaction types and indexer semantics
- Dashboard & protocol UI — batch lifecycle, mining, reputation, Shapley, trust, and Bitcoin flows in one place
- Full batch pipeline — create → commit → close → reveal → settle with deterministic fair ordering
- Credential registry — lifecycle events mint positive/negative reputation signals automatically
- Shapley DAG + incentives — fair distribution with logarithmic scoring and dependency modeling
- Trust report — per-user and batch-level anomaly detection with severity tiers
- Demo API —

GitHub renders GIFs as normal images, so an animated demo.gif autoplays inline in the README—same pattern as projects that use demo.gif instead of <video>. The full-quality recording (longer run, sound) is still cogproof-demo.mp4 (Git LFS). On that file page use Download for a local copy; clones need git lfs install and git lfs pull.
What you’ll see in the demo
- Landing & narrative — how CogProof fits into Bitcoin-native agent economies
- Dashboard — reputation tiers, trust signals, and module navigation
- Batch & mining flows — commit-reveal lifecycle and settlement concepts in the UI
- End-to-end story — how credentials, Shapley logic, and trust analysis tie together

Core modules (expand)
- Commit:
hash(output || secret)on-chain — zero information leakage - Reveal: output + secret after the window closes
- Settle: XOR secrets + block entropy → Fisher-Yates shuffle → deterministic validation order
Every protocol lifecycle event can yield a verifiable credential (honest reveal, failed reveal, high contributor, compression miner, etc.). Reputation tiers: NEWCOMER → BRONZE → SILVER → GOLD → DIAMOND.
Marginal contribution across coalition orderings, Lawson λ minimum floor, DAG dependencies, logarithmic scoring to limit burst dominance.
Detectors include selective reveal, sybil clusters, compression plagiarism, reputation churn, collusion rings, and velocity spikes. Trust tiers: FLAGGED → SUSPICIOUS → CAUTIOUS → NORMAL → TRUSTED.
Symbolic compression as proof-of-work; lossless decompression verifies honest work.

Everything is designed to map onto CogCoin’s existing transaction vocabulary: commits/reveals as validated TX pairs, credentials as DATA_UPDATE / FIELD_REG, reputation via REP_COMMIT and REP_REVOKE, Shapley outputs anchored by hash on-chain, trust derived from indexer-visible history. No new consensus. No sidechain. Just Bitcoin + an indexer.
