Cardano Founder Warns of Quantum Computing Risks

The Big Picture: Key Points

  • Cardano founder Charles Hoskinson has raised concerns about the pace of quantum computing development and its potential effects on Bitcoin security.
  • DARPA is involved in a structured program assessing quantum computing progress, with 11 companies participating, including IBM and Quantinuum.
  • Blockchain developers are studying post-quantum upgrades as part of long-term planning, with proposals such as BIP-360 and BIP-361 aiming to improve Bitcoin's security.

The development of quantum computing is progressing at a rapid pace, and Cardano founder Charles Hoskinson has warned that the risks associated with it may arrive sooner than expected. This warning comes as global research programs continue to test the capabilities of quantum hardware and encryption limits. DARPA, in particular, has involved 11 companies, including IBM and Quantinuum, in a structured program to assess quantum computing progress.

The program uses a three-stage evaluation model to determine whether functional quantum machines could emerge by 2033. This timeline is crucial, as it will help determine 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, which will clarify whether quantum computing remains a distant issue or a nearer concern.

Quantum Computing Risks and Bitcoin Security

Charles Hoskinson stated that

The quantum threat is real and it’s coming much faster than everybody is anticipating
. This warning is echoed by Ethereum developer Justin Drake, who has indicated that there is a measurable possibility of cryptographic risks emerging around 2032, linked to ongoing progress in quantum computing research and hardware development. Bitcoin's security currently depends on elliptic curve digital signatures, which are still considered secure under existing computing power.

However, 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. Nevertheless, the potential risks are being taken seriously, and developers are exploring proposals such as BIP-360 and BIP-361 to improve Bitcoin's security. BIP-360 focuses on post-quantum signature support, while BIP-361 proposes a phased migration away from legacy address formats.

Blockchain Response and Preparation Efforts

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.

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.
