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?
Do you mean what if Bitcoin is copied or recreated?
If that is what you mean, then my answer is no way. Because I have seen many projects that even tried to be a competitor or replacement for Bitcoin, but in the end they failed, and that also happened to Ethereum. Come on, even for Ethereum no one has been able to try to copy its success, let alone Bitcoin, right? Of course it is.
