Cardano founder Charles Hoskinson has outlined a strategy to secure the network in a post-quantum world.

In a Feb. 20 broadcast, he emphasized the urgency of adapting blockchain systems as quantum computing advances.

Hoskinson’s comments come as he praises Microsoft’s Majorana 1 quantum chip. The Cardano founder said the technology is one of the most significant advancements in quantum computing history

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 stated that the network will introduce a proof chain that functions as an independent verification layer to prepare for this groundbreaking technology.

This additional security measure will leverage advanced cryptographic techniques, including Mithril certificates and post-quantum signatures, to maintain the integrity of past transactions.

However, Hoskinson noted that these solutions come with trade-offs, such as slower processing times and increased data requirements, which could introduce inefficiencies.

Nonetheless, he pointed out that the long-term objective is to integrate the proof chain into the main blockchain, transitioning from traditional elliptic curve cryptography to quantum-resistant alternatives.

He added that researchers are exploring new ledger models beyond the standard UTXO framework to enhance security and scalability.

Challenges and roadmap

Quantum computing is evolving rapidly, potentially outpacing cryptographic standards within the next decade.

Despite this urgency, post-quantum cryptography remains in its developmental stage, with multiple competing approaches, including hash-based and lattice-based encryption. To stay ahead of these challenges, Cardano will collaborate with industry experts and allocate significant resources to research.

Hoskinson furthered that while Cardano would prepare for this technology, the ecosystem would wait for industry-wide consensus before making significant modifications.

He noted that the quantum-resistant features could be introduced within the next few years, beginning with the proof chain, while fully adopting post-quantum security measures will take longer. However, research efforts will be a priority in the coming years to ensure the network remains resilient.

Tech giant Google took the world by storm on Monday by unveiling its quantum computing chip – Google Willow – while raising doubts on whether it can break the Bitcoin network in the future. For years, concerns have stayed that quantum computing is a threat to blockchain technology. While analyzing the prowess of Google’s computing chip, market analysts noted that it doesn’t pose any threat to the Bitcoin network in the near future.

Does Google Willow Pose A Threat to Bitcoin?

To understand this, first, we need to have a basic understanding of the Bitcoin seed phrase. A Bitcoin seed phrase is a list of 12 or 24 random words that act as a master key to a wallet. These phrases are backed by Elliptic Curve Cryptography (ECC) and hashing algorithms, creating math problems so complex that even the fastest conventional computers can’t solve them.

However, quantum computers can potentially crack these codes much faster than classical computers by solving the Discrete Logarithm Problem using algorithms like Shor’s.

Now, the current power of Google Willow computing chip is 105 qubits. Although this chip can solve computational problems in less than 5 minutes, which would otherwise take 10^25 years, it still can’t breach into the Bitcoin ecosystem.

This is because to break into the Bitcoin network and decode its encryption, it would take an estimated 1 million qubits. Even cutting-edge quantum systems today cannot tackle problems as large as those posed by Bitcoin’s ECC. However, the buzz surrounding Willow’s threat to quantum computing has already led to Bitcoin and altcoin market correction earlier today.

Future Concerns and Bitcoin’s Defense

Experts predict quantum computers could pose a realistic threat to Bitcoin in 10–20 years, depending on advancements in quantum hardware and error correction. A sufficiently powerful quantum could possibly break the BTC encryption while guessing the BTC seed phrases and its wallet key, thereby ultimately jeopardizing wallet security.

On the other hand, Bitcoin developers are actively exploring quantum-resistant cryptography, which involves creating new algorithms that even quantum computers would struggle to solve. Thus, although Google Willow is a groundbreaking chipset in the market, it is far from breaking through the Bitcoin network security at this point. However, as technology evolves, Bitcoin’s preparedness for future quantum advancements will remain a critical focus.

Market analysts noted that the Google Willow quantum chip was developed under controlled lab conditions. For it to pose a credible threat to cryptocurrency, two critical factors would need to align:

1. Affordability: Willow would need to become inexpensive enough for widespread adoption.
2. Accessibility: The technology would need to be widely available, including to malicious actors.

Currently, Bitcoin has been facing rejection at $100K levels amid huge selling pressure from long-term holders. As of press time, the BTC price is trading 1.27% down at $97,508 with a market cap of $1.929 trillion.
