QSB: Smart Contracts, Consensus, and Quantum Cryptography

The term “quantum-secured blockchain” pertains to a sort of blockchain technology designed to withstand attacks from quantum computers. Quantum computers are a relatively modern computers meant to work with the principles of quantum physics. They can perform certain computations substantially quicker than standard systems. One of the most significant worries regarding quantum computers is the possibility that these machines would be able to break down the encryption that has been employed to safeguard blockchain networks. Blockchains that are quantum-secured adopt strategies and mechanisms that are quantum-resistant to prevent quantum computers from accessing the data or information that is stored on the network. Even though this blockchain technology is only in its infancy stage now, it is anticipated that it will be one of the future possibilities for protecting data on blockchain networks. Investigation of new forms of encryption that cannot be broken by quantum computers, such as those based on lattices, codes, and multivariate quadratic equations, is underway.
