Millions of Bitcoin stored in addresses with exposed public keys now risk becoming easy targets once capable quantum computers emerge. Cardano co-founder Charles Hoskinson capitalized on this moment to warn that Bitcoin could be dethroned from the top spot if its governance fails to agree on a transition to a quantum-resistant system.
In an interview with The Starting Block aired on July 24, 2026, Hoskinson described Bitcoin’s current network structure as frozen in time. He noted that major changes on the network move far too slowly because they require consensus from too many factions with competing interests, ranging from developers, miners, and node operators to millions of everyday users.
Yet behind the sharp criticism, an irony is unfolding in his own backyard.
Diverging Paths to Secure the Network
Bitcoin has long relied on elliptic curve cryptography - specifically the ECDSA and Schnorr models - to validate every coin transfer. On paper, quantum computing machines have the capability to dissect public keys already recorded on the ledger and reverse-engineer the code to gain access to private keys. Millions of BTC sitting in early addresses fall into the most vulnerable zone.
Mitigation efforts are not nonexistent. The U.S. standards agency, NIST, recently established a suite of new algorithms specifically designed to counter quantum attacks. Bitcoin Optech developers have also prepared the BIP 361 proposal, detailing a roadmap to transition away from ECDSA and Schnorr. The migration path has been mapped out, and they are now waiting for the community to agree on a replacement system.
On the other hand, Hoskinson continues to argue that Cardano’s formal decision-making model offers a more definitive way forward for such a critical transition. The ADA network recently completed its transition of power to the community via the Plomin hard fork upgrade in early January 2025. The network positions itself as a spiritual successor to Bitcoin by retaining a fixed supply cap, while introducing smart contract functionality and tiered governance. Its new rules allow coin holders to cast votes directly or delegate them to representatives, balanced alongside the power of stake pool operators and a constitutional committee.
The Founder’s Plan Backfires
That claim of high-level readiness, however, remains unproven in practice. In fact, the Cardano network currently lacks quantum defenses as well, with its team still in the phase of evaluating technical designs to schedule an upgrade.
Instead of demonstrating a smooth approval process, the system Hoskinson designed has stalled his own plans. A series of events throughout 2026 revealed that elected representatives openly challenged several proposals from Hoskinson and development firm Input Output. Among the key documents rejected by the community was a research proposal on quantum-resistant cryptography and the Ouroboros Leios upgrade model.
This delegate pushback also targeted Hoskinson’s claim that Cardano’s network throughput would surge 60-fold following the Leios upgrade. The community was well aware that the projection was merely the founder’s personal estimate, rather than definitive data from real-world testing. Hoskinson may be right about Bitcoin’s slow pace of progress, but his own coin holders are now teaching a vital lesson: even an organized voting system is useless if the founder fails to convince his own community.
