SUI claims its architecture gives it an edge as the crypto industry prepares for a post-quantum future.
Kostas Chalkias, co-founder and chief cryptographer at Mysten Labs, says Bitcoin will be the first blockchain to be attacked when quantum computers become powerful enough to break current cryptographic systems.
In a recent interview on the When Shift Happens podcast, Chalkias pointed out Satoshi Nakamoto’s addresses have exposed public keys, making them easy targets.
“In my opinion, all chains should start migrating now, until 2030,” he said.
Quantum threat: when could it strike?
Ten years ago, cryptographers predicted that quantum “doomsday” would arrive around 2030-2035. Chalkias now believes the threat will not recur for at least five years. But he added that AI could accelerate breakthroughs in quantum computing in ways no one can predict.
Government agencies such as NIST have already started requiring quantum-safe algorithm support. Pressure is increasing on blockchain networks to catch up.

SUI Says it has an edge over Ethereum and Solana
Chalkias explained that SUI uses the EDDSA algorithm. He claims it is better suited for quantum security than ECDSA, which powers Bitcoin and Ethereum.
His team also invented an algorithm that makes existence possible SUI addresses become quantum safe via a one-click upgrade using post-quantum zero knowledge proofs. He made it clear that this solution does not work for Ethereum or Bitcoin.
Currently, no quantum-safe blockchain is in the top 40 by market capitalization. The Ethereum Foundation is funding research into the problem, and the Solana community is exploring new quantum-safe address types.
Big names are already choosing SUI
Google has chosen SUI to test agent AI payments. The Greek stock market also opted for this SUI compared to other blockchains due to its flexibility for different use cases.
Chalkias previously worked on Facebook’s Libra project and WhatsApp’s encrypted payments. He has more than 15 years of experience in cryptographic research.
