Cardano founder Charles Hoskinson has raised concerns about the pace of quantum computing development and its possible effects on Bitcoin security. His comments follow ongoing global research programs that test quantum hardware capabilities and encryption limits.
DARPA and several technology companies are advancing evaluation frameworks for future systems. At the same time, blockchain developers continue to study post-quantum upgrades as part of long-term planning across crypto networks.
DARPA has involved 11 companies, including IBM and Quantinuum, in a structured program assessing quantum computing progress. The project uses a three-stage evaluation model to determine whether functional quantum machines could emerge by 2033.
The process also examines whether such machines may affect current encryption methods used in digital systems, including blockchain networks and financial infrastructure.
Researchers expect early results within 12 to 24 months to clarify whether quantum computing remains a distant issue or a nearer concern. The findings may guide planning for cryptography upgrades in multiple sectors.
Industry participants continue to monitor hardware improvements and error correction progress, which remain key factors in determining future risk levels for encryption systems.
Cardano founder Charles Hoskinson stated that quantum risk is developing faster than expected. He said, “The quantum threat is real and it’s coming much faster than everybody is anticipating”.
Ethereum developer Justin Drake has also indicated that there is a measurable possibility of cryptographic risks emerging around 2032, linked to ongoing progress in quantum computing research and hardware development across different systems.
Bitcoin security currently depends on elliptic curve digital signatures, which are still considered secure under existing computing power.
At the same time, theoretical quantum methods could weaken these protections if large-scale quantum machines are eventually developed. As of 2026, no quantum system has reached the required scale to break these cryptographic standards.
Bitcoin development discussions include proposals such as BIP-360 and BIP-361. BIP-360 focuses on post-quantum signature support while BIP-361 proposes phased migration away from legacy address formats.
Each option carries technical adjustments for wallet systems and transaction verification. Developers continue reviewing how these changes would affect long-term network stability and user migration processes.
Institutional stakeholders have been mentioned in discussions regarding potential migration effects. Concerns remain around how markets could react if older wallet structures are exposed in future scenarios. As a result, different frameworks are being discussed to limit disruption while keeping exchanges and custodial services running smoothly. Developers are still debating how fast these changes should be introduced and how wide their scope should be.
Work on broader blockchain readiness is also ongoing. Ethereum developers are upgrading systems to strengthen cryptography across accounts and consensus layers. In addition, the XRP Ledger has introduced staged plans to add quantum-resistant signatures, while Hedera already relies on hash-based cryptography that aligns with NIST standards.
These efforts are linked to global post-quantum standards such as ML-DSA and SLH-DSA which are still being reviewed across different industries.
At the same time, investors and developers are watching migration plans and security updates closely. Many users are advised to avoid reusing addresses and to follow protocol updates as they happen. Wallet providers may need to adjust their systems to support new cryptographic models. Research continues into how to improve security while keeping network performance stable across blockchain and financial systems.
