A proposed upgrade aimed at protecting Bitcoin from future quantum computing threats has sparked a heated debate about the network’s ability to adapt. BIP-361, created by Jameson Lopp and several co-authors, suggests restricting spending from legacy Bitcoin addresses after about three years and rendering unmigrated coins permanently unusable after an additional two years.
Key Facts About BIP-361 and Quantum Risks
As of March 1, 2026, over 34% of Bitcoin had exposed public keys on-chain, making those coins vulnerable if quantum computers become powerful enough to break current cryptographic defenses. The existing recovery frameworks only cover wallets based on the BIP-32 standard, leaving around 1.1 million BTC, believed to be owned by Satoshi Nakamoto, outside their scope.
The urgency to address these vulnerabilities comes amid growing concerns over Bitcoin’s resilience to technological advances. However, the focus has shifted from purely cryptographic challenges to governance issues: can Bitcoin’s community, known for resisting changes, agree on critical upgrades before a quantum threat fully materializes?
Industry Voices on Bitcoin’s Governance Challenges
Charles Hoskinson, co-founder of Cardano, recently highlighted this governance dilemma during an appearance on The Starting Block podcast. He argued that Bitcoin’s strength in immutability also limits its ability to evolve swiftly, calling it "frozen in time." Hoskinson pointed out that without a clear mechanism to coordinate changes, Bitcoin may struggle to respond to quantum risks effectively.
In contrast, Cardano’s more flexible governance model allows for on-chain voting and coordinated upgrades. For instance, Cardano’s network recently rejected a funding proposal through delegate voting, exemplifying its capacity for collective decision-making. Bitcoin, lacking such formalized voting structures, is now facing pressure to navigate this issue.
BIP-361 proposes a phased migration plan that would compel users to move coins off vulnerable legacy addresses within specified timeframes. The debate around its adoption reflects broader questions about Bitcoin’s future-proofing and governance dynamics.
