I see a lot of post about #QBTC and Honestly I don't know what it is. So I do a research about it.
Here this is what I found.
What is Quantum Bitcoin Cash?
Quantum Bitcoin Cash is the idea of upgrading Bitcoin Cash with post-quantum cryptography, so users' coins remain secure even if powerful quantum computers can break today's digital signatures.
Why is it important?
Current Bitcoin Cash uses elliptic curve cryptography (ECDSA/Schnorr), which is considered secure against today's computers. However, a sufficiently advanced quantum computer could potentially derive private keys from exposed public keys, putting some funds at risk.
Quantumroot
One of the most notable developments is Quantumroot, a proposed post-quantum vault system for Bitcoin Cash. It aims to:
Protect BCH from future quantum attacks.
Allow users to migrate funds to quantum-secure addresses.
Use standardized, hash-based cryptography rather than relying on newer experimental methods.
Benefits
🔒 Stronger long-term security
💰 Better protection for stored BCH
🚀 Helps prepare the Bitcoin Cash network for the quantum computing era
🌍 Keeps Bitcoin Cash viable as peer-to-peer electronic cash in the future.
