Tokenized gold is rapidly emerging as one of the most promising real-world asset (RWA) use cases in digital finance. By representing ownership of physical gold through blockchain-based tokens, tokenized gold combines the stability of precious metals with the efficiency of modern financial infrastructure. As financial institutions explore tokenization, security is becoming increasingly important. Quantum-secure tokenized gold aims to protect digital ownership records against b

At the CB+DC Conference 2026, Maxwell Denega presented Quantum Chain’s vision for the future of digital money and why quantum security must become a foundational requirement for CBDCs, stablecoins and national payment systems. The presentation, titled “QAI and the Future of Digital Money: Securing CBDCs, Stablecoins and National Payment Systems,” explored how the rapid advancement of both quantum computing and artificial intelligence is beginning to reshape the security assum

Introduction Quantum computing is advancing toward the capability required to break widely used cryptographic systems. This directly impacts financial infrastructure, including blockchain networks that rely on elliptic curve cryptography. Recent research from Google provides updated estimates on the quantum resources required to break ECDLP-based systems such as secp256k1. These systems secure Bitcoin, Ethereum, and most digital asset platforms. This article examines: the cur

Max Denega, Founder and CEO, was invited to speak at an exclusive, closed-door session hosted at KPMG’s Singapore head office, attended by senior leaders across financial institutions. The focus was clear: the industry needs to evolve considering the structural security shift driven by quantum computing and AI. Max presented a unique perspective considering the integration of blockchain infrastructure with post-quantum security, which positioned Quantum Chain as a streamlined

The convergence of AI and Quantum Computing produces a structural tension: blockchain adoption is accelerating, while the underlying security model is being eroded by emerging technologies. Implications for Blockchain Infrastructure Transition The convergence of artificial intelligence (AI), quantum computing and distributed ledger technologies introduces a new class of systemic risks to digital financial infrastructure. While enterprise adoption of blockchain continues to ac

HTTPQ is a quantum-secure evolution of HTTPS. Instead of patching TLS, HTTPQ redesigns the transport trust model... Financial institutions rely on HTTPS and TLS certificates to secure payments, APIs, custody systems and financial messaging. These certificates were built on RSA and elliptic curve cryptography, which quantum computers are expected to break. Even as companies like Google introduce post-quantum updates such as Merkle Tree Certificates and ML-DSA signatures, these

The Security Assumptions of Blockchain Are Changing For more than a decade the blockchain industry has operated on a simple idea. Open protocols open code and permissionless systems create stronger networks because anyone can inspect them and improve them. Transparency was treated as security. That assumption is now being tested by two forces developing at the same time: artificial intelligence and quantum computing. AI systems can now analyze large software codebases faster

Why Your Current Blockchain Providers are at risk The security of modern blockchains rests on mathematical assumptions that are now under credible pressure from “harvest now, decrypt later” strategies. The largest networks (including Bitcoin, Ethereum and Solana) rely on elliptic curve signature systems such as ECDSA and Ed25519. These systems assume that deriving a private key from a public key is computationally infeasible. A sufficiently powerful quantum computer running S

The Risk Quantum Computing Has Over Digital Currencies Stablecoins are becoming core instruments in financial systems. They are used for settlement, treasury management, remittance, liquidity routing and on-chain capital markets. As adoption increases, the underlying security assumptions move from technical detail to systemic importance. Visualization of ECDSA, Most stablecoins today are issued on blockchains that rely on classical cryptography, particularly elliptic curve-ba
