(BTCWires.com) In the future, as the threat of quantum computers becomes more pronounced to the public key cryptography, there are certain changes that blockchain can implement to be quantum resistant. Projects like the QRL (Quantum Resistant Ledger) already have their implementation of a blockchain which won’t be influenced by the exponential hike in computational power of quantum computers. Quantum Resistant Ledger makes sure about the quantum resistance by ensuring that private keys are generated in a complicated way that depends on hash-based cryptography in comparison with the current public key cryptography.
This threat of quantum computing comes from the fact that quantum computing takes benefit from quantum QUBITS or Quantum Bits, that can exist in any superposition of values between 0 and 1. Therefore, it processes much more information than just 0 or 1, which is actually the limit of classical computing systems.
