Google has set a 2029 deadline for transitioning to post-quantum cryptography (PQC), warning that the “quantum frontier” could also be nearer than it seems.
Google mentioned Wednesday that speedy advances in quantum computing {hardware} and quantum error correction, in addition to up to date estimates of how rapidly quantum machines can break by present encryption requirements, heighten the necessity to act rapidly.
“Quantum computer systems will pose a big risk to present cryptographic requirements, significantly encryption and digital signatures,” Google mentioned, whereas additionally mentioning {that a} transition to PQC is critical for customers to make use of authentication providers securely.
That is the primary time Google has set a schedule for rolling out post-quantum options throughout its merchandise. The 2029 timeline is quicker than some business predictions for Q-Day, the purpose at which quantum computer systems can be highly effective sufficient to interrupt present public-key cryptography.
“It is our accountability to guide by instance and share our bold timeline, which we hope will present the readability and urgency wanted to speed up the digital transition not solely at Google however throughout the business.”

Google’s urgency comes as the corporate continues to develop its Willow quantum chip, the business’s strongest quantum chip with 105 qubits of computing energy.
There are additionally rising considerations that quantum computer systems might critically disrupt the crypto business by breaking the cryptographic algorithms used to guard digital belongings. Nonetheless, there may be nonetheless debate as as to whether solely crypto wallets with uncovered public keys are weak, or whether or not all cash are in danger.
Crypto networks additionally give attention to post-quantum upgrades
The Ethereum Basis on Tuesday launched a “post-quantum Ethereum” useful resource hub targeted on securing the blockchain from future quantum computing threats and securing billions of {dollars} of worth on the community.
The post-quantum staff plans to implement quantum-proof options for Ethereum on the protocol degree by 2029, adopted by options focusing on the execution layer.
In January 2025, Solana builders created a quantum-proof vault on the Solana blockchain to guard customers’ funds from quantum threats by implementing a posh hash-based signature system that generates a brand new key each time a transaction is made.
Nonetheless, to entry this characteristic, Solana customers might want to retailer their funds in a Winteritz vault slightly than a daily Solana pockets, as it isn’t a network-wide safety improve.
In the meantime, the Bitcoin ecosystem is more and more divided over what actions, if any, builders ought to take.
Blockstream CEO Adam Again, probably the most influential voices within the Bitcoin ecosystem, says quantum dangers are extensively exaggerated and will not require motion for many years.
In the meantime, safety researcher Ethan Heilman and colleagues proposed a brand new output kind for Bitcoin known as the Pay-to-Merkle route by Bitcoin Enchancment Proposal 360 (BIP-360). That is supposed to guard Bitcoin addresses from potential brief publicity quantum assaults.
Nonetheless, its implementation might take seven years, Heilman advised Cointelegraph in February.
