QUANTUM ALLIANCE just launched — a consortium of 9 orgs (Quantus, Keystone, Hacken, etc.) building standardized frameworks to assess $BTC's resistance against quantum computing attacks.
The threat model: ~6.04M $BTC sitting in older address formats (P2PK) could theoretically be vulnerable once quantum computers hit sufficient qubit counts + error correction thresholds. Right now, no existing quantum system comes close to breaking ECDSA (secp256k1), but the alliance is prepping evaluation standards before that window closes.
This is less about immediate risk, more about future-proofing cryptographic assumptions. If you're holding $BTC in legacy addresses, migrating to SegWit/Taproot reduces attack surface by not exposing public keys until spend time.
