Bitcoin is lagging in quantum-resistant development,

Bitcoin Lags Ethereum in Quantum Resistance Race, Says Nic Carter

Nic Carter, founding partner at Castle Island Ventures, is sounding the alarm. In a recent post, he pointed out that Bitcoin developers are moving too slowly on quantum-resistant upgrades. Meanwhile, Ethereum has made post-quantum cryptography migration a top strategic priority, with a roadmap targeting 2029.

Here's the issue. Most blockchains today rely on elliptic curve cryptography (ECC). And that, Carter warns, faces a real threat from quantum computers down the line. "Whether it's three years or ten years, the era of ECC is coming to an end." His take? Networks need to build cryptographic agility right into their architecture.

Ethereum, for its part, is already on it. Vitalik Buterin laid out a quantum resistance roadmap back in February, covering validator signatures, data storage, accounts, and proof mechanisms.

ARK Invest previously estimated that about one-third of all bitcoin is exposed to quantum risk—though they called it a "long-term" concern. Carter's view? If the Bitcoin community doesn't get moving, the ETH/BTC ratio will eventually start to reflect that divergence in priorities.
