Controling paid access to digital data is hard because once access is given it can easily be copied. Angor uses very simple concepts in bitcoin script (timelock and multisig) to achieve the gradual release of funds to founders, and we leverage taproot for a more efficient way of doing that. But Angor uses base layer, I would assume pay for digital consumption doesn't need to use base layer because it is probably sending smaller amounts, which means L2 is an option, and you have more complex smart contracts in L2. Do you have a more specific idea in mind?
