📄 Description
Adds the InfoBitcoin Bitcoin Quantum Address Checker to Resources > Web-tools (alphabetical position, before Boxentriq).
Why it's awesome: it makes the practical side of the quantum threat to ECDSA tangible. Paste a Bitcoin address and it tells you whether its public key is already visible on-chain - the precondition for a future attack with Shor's algorithm - or still protected behind a hash (P2PKH/P2WPKH never spent), with an explanation of each case (Taproot outputs, key reuse, spent addresses). 100% client-side (static HTML + JS querying the public mempool.space API from the user's browser; the address never touches a server). Free, no sign-up, available in English and Spanish. Source code: https://github.com/optimaquantum/bitcoin-quantum-checker (MIT).
