New Blockchain Variant Resists Quantum Cracking

Many have wondered whether the power of quantum computers could one day make it easy to crack digital encryption,  including the encryption used with conventional blockchain technology.  The Inter-American Development Bank (IDB) has joined with Cambridge Quantum and Tecnologico de Monterrey to develop a new form of blockchain that is resistant to quantum cracking.
To address this challenge, “...a post-quantum cryptography layer that protects networks and offers resistance to quantum computer attacks was developed on the LACChain Besu blockchain network, based on Ethereum technology. Transactions and communications were protected with quantum-proof keys from CQ’s IronBridge platform, which uses quantum computers to generate certified entropy.”
