Charles Hoskinson is the Cardano founder and he has described a strategy for securing the network in an post-quantum era.
On February 20, he stressed that blockchain systems must be adapted as quantum computers advance.
Hoskinson’s comments come as he praises Microsoft’s Majorana 1 quantum chip. Cardano’s founder, John Cardano, said that the Cardano technology was one of the biggest advances in quantum computing.
Microsoft CEO Satya Nadella described the chip as small enough to fit in the palm of a hand yet capable of solving problems beyond the reach of all the world’s current computers.
Cardano’s plan for Quantum security
Hoskinson said that in order to be ready for the groundbreaking technology, the network would introduce a proof-chain that will act as an independent layer of verification.
The additional security measures will use advanced cryptographic methods, such as Mithril Certificates and Post-Quantum Signatures, in order to preserve the integrity of previous transactions.
Hoskinson pointed out that the solutions are not without their tradeoffs. These include slower processing speeds and higher data requirements.
He pointed out, though, that the ultimate goal is to incorporate the proof-chain into the main Blockchain, and to transition away from the elliptic curvature cryptography of old to alternatives resistant to quantum.
Researchers are also exploring other ledgers beyond the standard UTXO model to improve security and scalability.
Challenges and Roadmap
Quantum computing has evolved rapidly and could surpass cryptographic standards in the next decade.
Even though this is a pressing issue, there are still many competing cryptographic approaches including lattice and hash-based. Cardano is collaborating with experts in the field and investing significant resources into research to keep up.
Hoskinson said that the Cardano ecosystem, which is preparing for this new technology, will be waiting for an industry-wide consensus to make significant changes.
He said that quantum-resistant security features, starting with proof chains, could be implemented within a few years. However, the full adoption of post-quantum measures would take longer. In the future, the research effort will remain a top priority to maintain the resilience of the network.
