Seb Audy, COO at AmericanFortress and Moon Pursuit Capital, argues that quantum-resistant wallets could be a decisive factor for institutional blockchain adoption because they address the long-term risk of elliptic-curve signatures being broken by a future quantum computer. He notes that institutions such as banks, pension funds and custodians may hold digital assets for decades, and the current approach of rotating keys or migrating to new addresses is impractical for positions that may not move for twenty years. Audy points to NIST’s post-quantum cryptographic standards, published in 2024, as a concrete planning reference and suggests that solutions protecting existing keys—potentially using zero-knowledge techniques—are more likely to gain traction than those requiring on-chain signature changes. He warns that larger keys and signatures could raise transaction costs, storage and performance concerns, making adoption dependent on manageable integration and auditability. 1
