Blockstream's CEO told Paris Blockchain Week that Bitcoin should build quantum-resistant upgrades now through voluntary migration, opposing BIP-361's plan to freeze coins in vulnerable address formats on a five-year timeline.
Olaoluwa Osuntokun's prototype lets users prove wallet ownership without a digital signature, solving the collateral damage problem in Bitcoin's most likely response to quantum computing threats.
A paper published by BTQ Technologies calculates that using quantum computers to mine bitcoin at current difficulty would demand roughly 10 to the power of 25 watts — approaching stellar energy output — and argues the real quantum threat lies in cryptographic signatures, not mining.
The USDC issuer's Layer-1 blockchain will ship post-quantum signature support at mainnet, making it one of the first production chains to offer opt-in protection against the threat that keeps cryptographers awake at night.
The 2025 Nobel laureate and Qolab co-founder warns that elliptic curve cryptography — the backbone of Bitcoin's security — is among the easiest targets for a sufficiently powerful quantum computer, giving the network a five-to-ten-year window to prepare.
