I'd love it if we can have apps where users don't need to directly buy AR to utilise the Arweave network.
Let's say Alice wants to archive a data permanently but only has Dai[1], while Bob holds AR and willing to upload Buyer's data for a certain fee. We can have a platform where the Bob(s) could post their price (ex: 1 Dai/MB). Alice would then lock her money to an escrow[2], followed by sending her data to Bob. Upon confirming the escrow and receiving the data, Bob would upload it, and finally give Alice the Arweave link. Alice releases the escrow and it is done!
[1] Dai is a stablecoin, a dollar pegged cryptocurrency (https://makerdao.com/)
[2] A naive escrow smart contract would be something where once the sender locks their money, he/she won't be able to withdraw it and only has the option to release the money to the seller. It should be possible to use trustless escrow service like Kleros (https://kleros.io/)
There are LOTS of work to be done but that's the general idea, what do you guys think?
