The approach has gained recognition from major institutions including Google, Coinbase, and IEEE, addressing concerns that quantum algorithms like Shor's could compromise private keys on conventional ECC-based blockchains.
Solana co-founder Anatoly Yakovenko has raised concerns that artificial intelligence could potentially break post-quantum cryptography (PQC) schemes currently protecting blockchain networks. The warning highlights undiscovered vulnerabilities in PQC implementations across the industry, with Solana's Anza team publishing research on quantum-resistant migration strategies that apply broadly to Bitcoin, Ethereum, and other chains.
Paradigm has proposed a cryptographic mechanism allowing Bitcoin holders to privately prove control of their private keys before quantum computers pose a threat, potentially offering a recovery option for dormant addresses if the network eventually sunsides older cryptographic standards. The solution addresses long-term quantum computing risks without requiring immediate movement of funds.
A Paradigm researcher has proposed PACTs (Prepare Against Cryptographic Threats), a mechanism allowing long-term Bitcoin holders to safeguard their funds against potential quantum computing threats without revealing activity on-chain or moving their holdings. This 'escape hatch' addresses growing concerns about quantum computers eventually breaking Bitcoin's cryptographic security.
Analysis by XRPL validator Vet reveals that 23.16 billion XRP (27% of supply) is quantum-safe, while 76.82 billion XRP remains exposed to potential quantum computing threats. Ripple has committed to making the network fully quantum-resistant by 2028, though dormant accounts holding 3.83% of exposed XRP present an unsolvable security challenge.

This analysis highlights a critical long-term security vulnerability as quantum computing advances threaten the cryptographic protections securing blockchain networks.
Coinbase's advisory board has released a 50-page report warning that quantum computing poses a significant future threat to blockchain security, despite current systems remaining safe today. The analysis emphasizes that the cryptocurrency industry must begin developing quantum-resistant solutions immediately rather than waiting for fault-tolerant quantum computers to emerge.
MIT Digital Currency Initiative director Neha Narula has proposed a practical roadmap for making Bitcoin resistant to future quantum computing threats, advocating for an incremental approach that allows users to secure their coins immediately rather than waiting for network-wide consensus on complex issues like handling dormant addresses.
RippleX researcher Aanchal Malhotra warns that the cryptocurrency industry faces an accelerating quantum computing threat with a rapidly closing preparation window. The warning highlights the urgent need for blockchain networks to implement quantum-resistant cryptography before quantum computers become capable of breaking current encryption standards.
