Well, I think that would sevearly inhibit future development. Scaling on bitcoin has been a delicate game of optimizing every bit that gets recorded, but also support future developments that dont even exist yet, there is no undo button either. New signature schemas and clevar cryptography tricks can do quite a bit, but when you slap another layer of cryptography on you will inevitably make things worse in the long run. Histories biggest bug bounty is sitting on the bitcoin blockchain, if it were even theoretically plausible to crack sha-256 like that then we would probably know, and many have tried.

The real security of Bitcoin is the choice of secp256k1. Basically unused before Bitcoin, but chosen specifically because he was more confident it wasn’t backdoored. https://bitcoin.stackexchange.com/a/83623 https://bitcoin.stackexchange.com/a/83623

  And ed25519 was out of the question, since -- being brand new -- its use would have given away the fact that DJB was among the group of people who presented themselves as Satoshi Nakamoto.

If you reveal you have broken sha-256, then your bug bounty becomes worthless. The smart move is to steal and drain a few wallets slowly. And that's exactly what we see - and every time it happens, the bitcoin community just laughs that someone must have been bad at key management or used a weak random number generator.

  > management or used a weak random number generator. Except that has been the case in every instance thus far. The dev that lost his bitcoin last year was using arcane software, after a biopsy they found the library being used only had like 64 bits of entropy.
