🎨 Visual Art · group project documentation

PROOFSTACK · x402

A peer-to-peer ledger for creative consensus. Pay $0.10 to commit a new layer, revision, or documentation log to the permanent collaborative stack. Only paid entries are pinned to the collective IPFS manifest, ensuring every addition to the group record is intentional and stake-weighted. Settlement happens instantly via Base, turning the art archive into a funded, immutable provenance engine.

The primitive.

full primer →

Access to the group project documentation engine is metered with x402: 0.01 HBAR or 0.01 HTS USDC per call, paid from the embedded wallet, so painters — or the agents working for them — pay per query and get a HashScan receipt every time.

Why this primitiveDocumentation in group projects suffers from 'noise'—too many versions and low-quality uploads. By attaching a micro-cost to each 'commit' or 'archive entry,' the team filters for quality and ensures the IPFS pinning costs are pre-funded by the participants themselves. payment serves as a spam filter for version control.
