I've read enough smart contract licensing terms to know that "you retain ownership" and "you retain meaningful control" are not the same sentence.
OpenLedger's Datanet lets contributors encode licensing terms directly into smart contracts. Which buyers can access your data, under what conditions, for what permitted uses. The architecture is more sophisticated than a simple upload and sell model and I give it credit for that.
What I kept circling back to was enforcement. A smart contract can restrict who purchases a license. It cannot stop a buyer from using the data outside the agreed terms once they have it. The license lives on chain. The data doesn't.
That gap between what the contract says and what the buyer actually does with your data exists in every licensing system ever built.
Blockchain doesn't close it. It just makes the terms more legible.
