What can be done to address the challenges that potential impact quantum computing may have on blockchains?

Quantum computing (utilising qubits), offers immense computational power but poses serious risks to blockchain technology. It can potentially break traditional cryptographic methods such as RSA and elliptic curve signatures, threatening blockchain security. With about 25% of Bitcoins currently vulnerable to quantum attacks, there is an urgent need for quantum-resistant cryptographic solutions. As quantum computing evolves, then adopting robust, quantum-resistant blockchain technologies is essential to safeguard the future of secure digital transactions. Professor Massimiliano Sala  warns of Q-day, a time when “quantum computers could bypass traditional encryption so threatening blockchain and Bitcoin security. Yet quantum computers could easily solve those problems that are foundational to digital signatures, thus potentially undermining the mechanisms that protect users' assets on blockchain platforms.”
