To save energy I propose to provide an alternative version of so-called NFT's. Here’s the deal: If you like any of the samples, you can buy it exclusively for a set minimum price. I will send you the original NFT together with a certificate of ownership and the promise not to sell it again (just check if it disappeared from the store). You don’t have authorship or publishing rights however. Half of the proceeds will be given to a good cause, chosen by you or me, in which case it will be communicated to you.
