The super promise died with crypto, now you have to add no backsies. My site uses No Backsies Proofs (NBPs) which are encrypted to prove that all my super promises are backed by a no backsie which is stored in the no backsie vault in Antarctica.
this is why my startup is launching backsies rollups for the blob, with null-effect prebacksies. this way everyone can be assured that any backsies issued are technically equivalent to just not making the original agreement! if you can discover a post-agreement backsie within the availability period of 0 days, and we can confirm it, we'll pay you $2,000 no backsies. so we have a market incentive not to lie to you. it's very efficient
I would feel more comfortable if your super promises were all on a blockchain, and we made No Backsie NFTs so people could clearly see these were legitimate and bid on them.
Later on moxie ends up writing a quick review of NBPs
> Instead of storing the data on-chain, NBPs instead contain a URL that points to the data. What surprised me about the standards was that there’s no hash commitment for the data located at the URL. Looking at many of the NBPs on popular marketplaces being sold for tens, hundreds, or millions of dollars, that URL often just points to some VPS running Apache somewhere. Anyone with access to that machine, anyone who buys that domain name in the future, or anyone who compromises that machine can change the image, title, description, etc for the NBP to whatever they’d like at any time (regardless of whether or not they “own” the token). There’s nothing in the NBP spec that tells you what the image “should” be, or even allows you to confirm whether something is the “correct” image.
