What if Bitcoin was reimagined today, under modern cryptographic assumptions, using a principled minimalist architecture designed for long-term auditability and zero-trust adversarial environments?
You could probably replace secp256k1 with technology that is more quantum resistant. Of course it doesn’t come without sacrifices. There will be some performances deficit as keys may be too large which makes transactions slow. It wouldn’t be compatible either with a lot of existing wallets we are used to
My question is how would it do in the marker? It can be marketed as future bitcoin ir better bitcoin addressing the concerns of many but will it be as successful as bitcoin? Maybe, maybe not. The reimagined bitcoin would have to start from scratch again while bitcoin remains to keep surviving. A reimagined bitcoin will just be another altcoin and not an exact copy of bitcoin.
