There's significant concern about the long term security of the Bitcoin network, since BTC rewards, which currently account for most miner revenue, keep dwindling at an exponential rate over time, and if total miner revenue gets low enough it becomes possible to exploit the bitcoin network to double-spend.
Proposed solutions to this usually involve either BTC price increasing to maintain security budget even with less rewards or an increase of onchain activity and, along with it, fees paid to miners, which has the side-effect of increasing fees for all other bitcoin users as well.
But what if there was another solution? One-shot signatures is a cryptography construction that enables the creation of public keys for which only a single signature can be generated, after which the keys self-destruct.
Now imagine every wallet stored a set of genesis UTXOs, and then when somebody paid you they would send you
