Hello Community
There may still be concerns among many investors that quantum computers could weaken existing cryptography in the future, so we are currently seeing an increase in this concern. Blockstream researchers have proposed a signature design that will maintain higher network throughput than post-quantum alternatives, and it is clear that their SHRINCS draft to secure quantum computers is still in its early stages.
Here is everything you need to know about this:
Blockstream researchers proposed SHRINCS, a post-quantum signature scheme for Bitcoin, designed to balance quantum resistance and minimize transaction throughput loss.
SHRINCS signatures start at 324 bytes and enable about three transactions per second, versus 0.36 for NIST SLH-DSA and 6.5 for current Schnorr signatures.
SHRINCS introduces one-time keys and operational complexities, remains unaudited, and would require a Bitcoin soft fork and broad consensus for adoption.
Blockstream researchers propose Bitcoin quantum-signature design to limit transaction capacity hit
