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
