The Threat of Quantum Computing

How Quantum Computing Changes Security Risks

The rapid progress in quantum computing poses a significant challenge for classical cryptography, raising deep concerns for blockchain and digital wallets. As discussed above, while smart-accounts enhance security through custom logic, their resilience depends on evolving to meet quantum-era risks.

Quantum computers utilize quantum mechanics for calculations that are infeasible for classical computers, fundamentally altering the security landscape. Their most immediate threats are:

Shor’s Algorithm: Capable of factoring large integers in polynomial time, this breaks widely used protocols (RSA, elliptic curve cryptography), undermining today’s secure communication backbone.
‘Harvest-now, decrypt-later’ scenario: Attackers may capture and store encrypted data today, then decrypt it in the future once quantum resources are sufficiently advanced.

Reliance on traditional cryptography will become unviable as quantum technology spreads. Investments and research initiatives globally highlight the urgency, with organizations like the U.S. National Institute of Standards and Technology (NIST) selecting post-quantum cryptographic algorithms for standardization—a move underscored by NIST’s official recommendations.

BMIC.ai’s focus on decentralized quantum resources offers an innovative approach by blending advanced blockchain governance with AI-driven optimization to reinforce the security infrastructure required for countering quantum threats.

Adopting post-quantum cryptography (PQC) is essential for establishing wallets resilient to quantum-era threats—a topic explored in further depth below.

Post-Quantum Cryptography and Its Necessity

The Role of PQC in Future Wallet Security

Post-quantum cryptography (PQC) has become central to the future of secure digital assets. Traditional cryptographic algorithms leveraged by blockchain transactions and online security depend on mathematical challenges now susceptible to quantum solutions like Shor’s Algorithm. PQC directly addresses these risks and is integral to building quantum-resistant wallets that align with BMIC’s vision.

PQC focuses on cryptographic systems that remain secure even against quantum computers. It leverages mathematical structures, such as:

Lattice-based problems
Code-based cryptography
Multivariate polynomial equations
Hash-based methods

Among NIST’s recognized PQC schemes are Kyber, Dilithium, and Falcon:

Kyber: A lattice-based encryption algorithm based on Learning With Errors (LWE) problem. It offers strong security with efficient, compact keys ideal for smart contracts and DeFi applications. Explore BMIC’s tokenomics for further integration roadmaps.
Dilithium: Another lattice-based solution, optimized for digital signatures with swift validation—crucial for high-frequency wallet operations.
