A leading Coinbase-backed Quantum Computing and Blockchain Independent Advisory Committee releases its first position paper, warning that sufficiently powerful quantum computers could crack current blockchain encryption and trigger a need for preemptive security upgrades.

Ethereum outlines a clearer roadmap to quantum resistance, while major networks like Solana, Algorand, and Aptos are already offering or planning quantum-resistant solutions.

Aptos is highlighted as well-positioned for a post-quantum transition due to its design that stores a public key as metadata and derives an address without hashing the public key, enabling key upgrades without moving assets.

Investors are reassured that current security remains intact but should monitor evolving developments and timelines.

The report notes significant usability and operational hurdles, including migrating millions of wallets and handling inactive or lost funds that do not upgrade.

A core dilemma is deciding the fate of wallets that never upgrade—whether to freeze, revoke, or leave assets vulnerable—and the recommendation is to make such decisions public early.

Inactive or lost wallets raise questions about asset treatment during upgrades and require predefined policies.

The report includes a disclaimer that it is informational, sourced from public platforms, and not financial or legal advice.

Various transition strategies are proposed, including hybrid systems and gradual upgrades to balance security and performance.

Flexible, multi-path transition plans are urged to preserve security and speed up upgrades when needed.

The overarching message is a call to begin preparations now rather than waiting for a crisis.
