TechFlow reports that on March 26, according to Cointelegraph, Nic Carter, Founding Partner at Castle Island Ventures, recently stated that Bitcoin developers are progressing slowly on quantum-resistant upgrades, whereas Ethereum has elevated post-quantum cryptography migration to its top strategic priority and established a roadmap targeting completion by 2029.
Nic Carter noted that the elliptic curve cryptography (ECC) widely adopted across blockchains today faces potential cryptanalytic threats from quantum computers: “Whether it’s three years or ten, the era of ECC is coming to an end.” Networks must therefore embed cryptographic agility into their foundational architectures.
On Ethereum’s side, co-founder Vitalik Buterin proposed a quantum-resistance roadmap in February this year, covering comprehensive upgrades to validator signatures, data storage, accounts, and proof mechanisms. Earlier research by ARK Invest indicated that approximately one-third of BTC is exposed to quantum threats—though it characterized this as a “long-term risk.”
Nic Carter believes that if the Bitcoin community fails to advance such upgrades promptly, the ETH/BTC exchange rate trend will gradually reflect the divergence in strategic priorities between the two networks.
