StarkWare just executed the first quantum-resistant $BTC transaction.

The catch? Regular nodes refused to relay it.

So the method isn't network-wide valid yet.

This is the gap between "technically possible" and "actually adopted."

Quantum resistance is coming, but Bitcoin's consensus layer isn't ready to enforce it. Node operators need to upgrade, or these txs stay isolated.

Worth watching if you're long-term bullish on BTC surviving post-quantum threats.
