Post-quantum Bitcoin wallet don add Q-Day protection

Post-Quantum Bitcoin wallet Quip wey Postquant Labs build wan protect Bitcoin ownership from di “Q-Day” threat wen quantum computers fit break elliptic-curve cryptography. Di Quip wallet dey use Layer 2 design wit Arch Network and WOTS+ one-time signatures. WOTS+ na post-quantum and e avoid elliptic-curve maths wey Shor’s algorithm fit eventually break. Postquant Labs talk say dis one dey deliver near-instant protection without changing Bitcoin core protocol. Di project don enter security-audit phase, dem don release code early for community review. Dem describe di approach as Bitcoin-native: Arch Network contracts fit interact wit mainnet without bridges or wrapped assets. Traders suppose note say dis launch land for middle of competing Bitcoin developer proposals. BIP-361 go phase out quantum-vulnerable addresses on fixed five-year schedule, and auto-freeze coins wey no migrate (numbers wey people dey mention: ~5.6M long-dormant coins and ~1M BTC wey dem link to Satoshi). Critics dey argue say e fit risk violating permissionless ownership. Separately, Paul Sztorc eCash hard-fork idea go add quantum resistance via sidechain. Project Eleven estimate about 6.9M BTC fit dey at risk because public keys dey visible on-chain. Postquant Labs CEO talk say protocol upgrades fit take 5–10 years, so dis post-quantum Bitcoin wallet path na faster alternative—though results go depend on audit outcomes and adoption.
