Cardano founder Charles Hoskinson has warned that quantum computing could threaten the security of cryptocurrencies before 2033. He argues that more than half of the crypto community faces a risk of quantum attacks and suggests a gradual shift to quantum‑resistant wallet addresses, citing bitcoin Improvement Proposal BIP‑361 as a possible solution.

Background

Quantum computers can solve certain mathematical problems far faster than classical machines, potentially breaking the cryptographic schemes that secure blockchain transactions. Bitcoin, ethereum, and other major coins rely on elliptic‑curve cryptography, which could become vulnerable if a sufficiently powerful quantum computer is built. The crypto industry has been exploring quantum‑resistant alternatives, but adoption has been slow due to technical and economic challenges.

What Happened

In a recent BeInCrypto Español post, Hoskinson stated that the probability of a quantum attack reaching the crypto space exceeds 50% before 2033. He highlighted BIP‑361, a Bitcoin Improvement Proposal that proposes a phased migration from current wallet addresses to new ones designed to withstand quantum attacks. The proposal would allow users to gradually move their funds to quantum‑resistant addresses, minimizing disruption. Hoskinson’s comments were echoed in a Bitcoinist article, which noted that the crypto community may need a major overhaul sooner than many anticipate.

Market & Industry Implications

Hoskinson’s warning could influence how exchanges, wallet providers, and developers prioritize quantum‑resistance. If BIP‑361 gains traction, it may prompt a shift in the Bitcoin ecosystem toward new address formats, potentially affecting backward compatibility and user experience. The prospect of a quantum threat may also accelerate investment in research on post‑quantum cryptography within the broader blockchain industry.

What to Watch

  • The status of BIP‑361: whether it receives formal support from Bitcoin Core developers and the wider community.
  • Announcements from major wallet and exchange providers about plans to adopt quantum‑resistant addresses.
  • Progress in quantum computing research, particularly milestones that could reduce the time needed to break elliptic‑curve cryptography.
