SUI Co-Founder Warns Bitcoin and Ethereum Not Ready for Quantum Threat

Source: CryptoNewsNet Original Title: SUI Co-Founder Warns Bitcoin and Ethereum Not Ready for Quantum Threat Original Link: Kostas Chalkias, co-founder and chief cryptographer at Mysten Labs, warns that Bitcoin will be the first blockchain attacked when quantum computers become powerful enough to break current cryptographic systems.

In a recent interview, Chalkias pointed to Satoshi Nakamoto’s addresses, which have exposed public keys, making them easy targets. He emphasized that “all of the chains should start the migration now until 2030.”

Quantum Threat: When Could It Hit?

Cryptographers predicted the quantum “doom day” would arrive around 2030-2035. Chalkias now believes the threat won’t show up in the next five years, but added that AI could speed up quantum computing breakthroughs in unpredictable ways.

Government agencies like NIST have already started requiring quantum-safe algorithm support, building pressure for blockchain networks to catch up.

SUI Claims Advantage Over Major Competitors

Chalkias explained that SUI uses the EDDSA algorithm, which he claims is better suited for quantum safety than ECDSA, the algorithm powering Bitcoin and certain major public chains.

His team invented an algorithm that lets existing SUI addresses become quantum-safe through a single-click upgrade using post-quantum zero knowledge proofs. Chalkias made clear that this solution does not work for Bitcoin or other competing blockchains.

Currently, no quantum-safe blockchain sits in the top 40 by market cap. However, major foundations are funding research into the problem, and several communities are exploring new quantum-safe address types.

Growing Industry Adoption

Google selected SUI to test agentic AI payments. The Greek stock market also chose SUI over other blockchains for its flexibility across different use cases.

Chalkias previously worked on Facebook’s Libra project and WhatsApp’s encrypted payments, bringing over 15 years of experience in cryptographic research to the discussion.
