The Controller-NFT Upgrade Is Now Live on PaperProof

This official release update explains the live controller-NFT upgrade and the resulting control model for new and migrated PaperProof series.

It helps readers understand the practical user impact, the protocol meaning of the change, and the direction it opens for artifact-native markets.

Author: PaperProof Labs Category: Protocol Upgrade The controller-NFT upgrade is now live on PaperProof mainnet. This is one of the most important protocol upgrades PaperProof has completed so far, because it changes what artifact control means at the protocol layer. PaperProof artifacts are no longer controlled only through a legacy owner-address model. Control is now bound to a controller NFT, which means the right to operate an artifact series can exist as a transferable on-chain asset while the artifact's public identity, version history, and authorship record remain intact. This is a major structural step for the protocol. At the same time, ordinary users should still find the experience familiar: reading, publishing, browsing, and updating artifacts should continue to feel like PaperProof. The point of the upgrade is not to make users think about extra complexity. The point is to make artifact control much stronger underneath the surface....
