Bitcoin could become the first blockchain to become public when quantum computers break today’s cryptography.
Governments are already pushing quantum safety standards, and major blockchains are racing to catch up.
Sui It claims its architecture gives it an advantage as the cryptocurrency industry prepares for a post-quantum future.
Kostas Chalkias, co-founder and chief cryptographer at Mysten Labs, says that when quantum computers become powerful enough to break through current cryptographic systems, Bitcoin will be the first blockchain to be attacked.
In a recent interview on the podcast “When Shift Happens,” Chalkias pointed out that Satoshi Nakamoto’s address exposes his public key, making him an easy target.
“In my opinion, all chains should start transitioning now by 2030.” he said.
Quantum threat: When will it strike?
Ten years ago, cryptographers predicted that a quantum doomsday would arrive around 2030 to 2035. Halkias currently believes this threat will not emerge for the next 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 begun requesting support for quantum-safe algorithms. There is increasing pressure for blockchain networks to catch up.

Sui Claims superiority over Ethereum and Solana
Chalkias explained: Sui Uses the EDDSA algorithm. He argues that it is better suited for quantum security than ECDSA, which underpins Bitcoin and Ethereum.
His team also has existing Sui A single-click upgrade with post-quantum zero-knowledge proofs makes your address quantum secure. He clarified that this solution does not work for Ethereum or Bitcoin.
Currently, there are no quantum-secure blockchains in the top 40 by market capitalization. The Ethereum Foundation is funding research into this issue, and the Solana community is exploring new types of quantum-secure addresses.

Chalkias previously worked on Facebook’s Libra project and WhatsApp’s crypto payments. He has over 15 years of experience in cryptographic research.
