InvArch

InvArch is an intellectual property Layer 1 built on Substrate that runs as a Polkadot parachain, decomposing creative assets into composable on-chain components: IP Files (any digital file as an NFT), IP Sets (folder-like structures), IP Licenses (configurable copyright and commercial terms) and IP Tokens (fungible fractions anchored to a set), with an on-chain innovation funding protocol to finance creative work. It targets rights and licenses in digital content that cannot execute automatically in transactions: once license terms are written as on-chain modules, ownership, access rights and revenue distribution take effect as tokens move. Cross-chain authentication uses Polkadot's XCM cross-consensus messaging layer to return file fingerprints minted on other chains for comparison, identifying copies and misappropriation.

In the Polkadot ecosystem its canary network Tinkernet runs on Kusama for early validation of new features; the INV4 frame ships as a Rust pallet with Web3 Foundation grant support, and third-party chains can reuse the module to issue on-chain IP assets. In practice, creators assemble files into IP Sets, define licenses and issue fractions, funders participate through the on-chain innovation funding protocol, and cross-chain authentication returns fingerprints of files minted elsewhere for comparison.
