Quantus Report Warns of Quantum Gap in Crypto Security

Quantus, a layer 1 blockchain for quantum-secure encrypted money, built with post-quantum cryptography from day one, is excited to announce State of Quantum Computing: What Crypto Can’t Afford to Ignore. A new research report is warning that quantum computing growth is compressing timelines toward a significant cryptographic risk threshold for the $2.7 trillion crypto ecosystem.

The Quantus report highlights a broadening gap between quantum abilities and the crypto industry’s preparedness across wallets, exchanges, custodians, validators, developers, and users. The given report states that crypto is passing through a period in which the risk timeline is outpacing the industry’s response mechanisms.

Older Crypto Wallets Remain Vulnerable to Quantum Cryptographic Attacks

Developments in error correction, gate fidelity, and cryptanalytic reserves estimates have minimized assumptions about the resources required to attack classical public-key systems. Major Blockchain networks are still at risk of breakage by Shor’s algorithm once quantum hardware becomes sufficiently advanced. Those blockchain networks are dependent on elliptic-curve signatures such as ECDSA and Ed25519

Public keys and historical address reuse have built a lasting attack surface across older wallets and legacy formats. Traditional internet infrastructure can update its cryptography without much action from the user. Blockchains build a heavier burden because assets are user-controlled, governance is expanded, and key material can remain uncovered indefinitely

Quantus Advances Wormhole Address Technology for Quantum-Resistant Bitcoin

Christopher Smith, CEO of Quantus, expressed his views. He said, “Crypto does not get a clean warning bell before Q-Day. If the industry waits until the threat is obvious, users will be asked to move value under pressure. The safer path is to build and migrate before that pressure arrives.” The report indicates a considerable finding regarding the scaling of a post-quantum version of Bitcoin.

A standard ECDSA transaction carries roughly 97 bytes of signature and public key. The similar transaction utilizing ML-DSA-87 carries almost 7187 bytes. That 74x increase would sharply minimize the number of transactions per block without architectural changes to Bitcoin itself. BIP 360 suggests a new post-quantum address type as one path forward.

Larger transactions strain block space, hardware wallets lack support, and unmigrated coins remain exposed. No single proposal sorts out all three. Quantus’s white paper elaborates on why architecture matters in that trade-off. Its Wormhole Addresses use Plonky2, STARK-style proof aggregation, and Poseidon2 to move verification off-chain and minimize the amortized storage cost of post-quantum transactions.

Quantum Computing Threatens Critical Blockchain Control Systems, Says Quantus

The danger comes to individual wallets. Stablecoin administration, validators, oracle networks, multisig custody systems, and governance contracts all rely on classical signatures. Negligence at these control points could harm lending markets, cross-chain liquidity, derivatives, automated market makers, and institutional custody.

Quantus names this inflection point the “Great Quantum Filter”, the moment money starts moving from vulnerable chains to quantum-secure ones. Quantus is launching with post-quantum cryptography and an architecture built for larger cryptographic payloads from day one.
