First Bitcoin Transaction with Quantum Resistance

Just sent the first quantum-resistant Bitcoin tx to mainnet using a new dual-signature method. Pretty excited about it!

Nice! Can you explain how it works? I’m not fully getting the dual-lock P2SH part.

Sure! It's ECDSA combined with a SHA256 hash preimage. Even if quantum computers break ECDSA, the hash preimage is still secure.

Wait, what if a miner knows the solution while the transaction waits in mempool? That’s a vulnerability, right?

Yeah but let's not forget the scenario where two quantum users compete to exploit this. It’d be wild with all those double-spends.

True but isn't that more of a theoretical scenario? If quantum computers can break ECDSA in seconds, the whole Bitcoin ecosystem might crash.

Exactly! If it takes 30s to break ECDSA, who will even care about that BTC? It’ll be worthless.

I’m curious too about the mask512 scheme. How does it stack up against other post-quantum solutions for security and size?

Does pre-image really make it secure? We can’t ignore Grover's Algorithm when real quantum power kicks in.

So we’re calling this a quantum-resistant transaction, but I see no actual quantum-resistant wallet yet. Just a single transaction, really.

Right? They’re mixing up terms here. Resistance can mean different things. We need a proper wallet that secures the bitcoins long-term.
