Important digital works increasingly move across unstable boundaries: storagelinks, social posts, repositories, preprint pages, datasets, software releases,chat archives, and application databases. These surfaces are useful, but none ofthem alone gives the work itself a neutral, durable, verifiable, and composableprotocol identity. PaperProof is a Sui-native protocol for durable digital artifacts backed byWalrus content storage. It treats a work not as a single uploaded file, but as anartifact series: a continuing object with typed versions, content commitments,official comments, likes, governance-aware parameters, canonical events, anddeveloper-facing SDKs. Recent protocol surfaces extend this model toagent-readable infrastructure: official Copilot prompts are stored as versionedPaperProof artifacts, and wallet-linked Copilot memory is discovered through alightweight on-chain registry while private memory bodies remain in MemWal andWalrus. The goal is not to replace academic archives, softwareplatforms, storage networks, social media, or community forums. The goal is togive important digital works a protocol layer beneath and beside those systems. This whitepaper explains the vision, user value, ecosystem role, developersurface, governance direction, PPRF relevance, sustainability principles,roadmap, and risks of PaperProof. Detailed object structures, error codes, andevent fields belong in the yellow paper; formal system analysis belongs in theacademic paper. This document is the ecological argument: why PaperProof shouldexist, who can build on it, and how it can grow without pretending to solve everysocial, financial, or editorial problem at launch.
