Crypto : Coinbase Urges Developers to Act Against Quantum

The digital asset industry is beginning to prepare for the arrival of quantum computing. This issue, still theoretical today, is nevertheless generating significant debates within the ecosystem. In this context, Coinbase is calling on developers to accelerate the necessary technical preparations. According to its advisory board dedicated to quantum, the transition must start immediately, especially to protect major networks like Bitcoin against future risks.

In brief

• Coinbase asks blockchain developers to start immediately the transition to post-quantum security.
• The advisory board believes the industry should not wait until a quantum threat becomes imminent.
• About 7 million Bitcoins could potentially be vulnerable in old or inactive addresses.
• Several options are being studied for non-migrated funds, from asset freezing to intermediate solutions.
• Major blockchain networks, including Bitcoin and Ethereum, are already beginning to prepare their adaptation to the post-quantum era.

Crypto: Coinbase Wants to Start the Post-Quantum Transition Immediately

Coinbase’s quantum advisory board believes the crypto community must immediately begin the necessary work to migrate to systems resistant to quantum computing. Developers should not wait for a consensus to be reached on handling vulnerable or abandoned funds.

According to the Coinbase report published Thursday, the committee specifies that no quantum computer is currently capable of breaking the cryptographic mechanisms used by blockchains:

No quantum computer can currently break blockchain cryptography, but timelines remain uncertain; the crypto community must therefore start preparing now, rather than debating the exact moment the threat might materialize.

However, timelines remain difficult to predict. This is why experts believe the Crypto ecosystem must anticipate rather than react in urgency.

Created in January, this board brings together researchers from academia and industry. Its mission is to study the potential consequences of quantum computing on blockchain networks and to suggest preparation paths.

One of the main concerns involves assets whose owners will never migrate to addresses protected against future quantum capabilities. This issue could become a major topic for the entire Crypto sector in the coming years.

Bitcoin Facing the Challenge of Vulnerable Addresses

According to the report, a quantum computer powerful enough to compromise the digital signatures used by Bitcoin could appear as early as 2030. This prospect fuels discussions about measures to adopt before such a situation occurs.

The committee states that “several million bitcoins (around 7 million) are today exposed in old addresses with public keys already visible.” These funds could become potential targets if quantum advances reach a sufficient level.

Researchers specifically mention holdings associated with addresses inactive for a long time, as well as some funds attributed to Satoshi Nakamoto. Considering different types of addresses, nearly seven million bitcoins are currently considered vulnerable in the long term.

Faced with this finding, the council presents several scenarios. The first involves permanently freezing assets that have not migrated past a defined deadline. The second proposes not imposing anything on users to respect Bitcoin’s historical principles and property rights associated with held funds.

Several Solutions Studied to Protect Blockchain Networks

The report also presents intermediate approaches. Some proposals aim to limit vulnerable fund movements per block. Others suggest using alternative cryptographic mechanisms to gradually replace current signatures.

Moreover, several industry players have already begun preparing this transition. In January, the Ethereum foundation set up a team in charge of coordinating its adaptation to post-quantum security. A few weeks later, a dedicated roadmap was also presented to support this evolution.

In April, Coinbase’s advisory board highlighted that some proof-of-stake networks could be particularly exposed to future quantum attacks. The signatures used by validators indeed rely on cryptographic mechanisms that could be affected by these technological advances.

Meanwhile, the Stellar Development Foundation recently unveiled a plan to guide its users towards quantum-resistant cryptography. Meanwhile, Bitcoin developers continue their discussions on migration methods for concerned funds and on the handling of assets remaining vulnerable.

For Coinbase’s board, the priority remains clear: the crypto community must move forward now on technical aspects in the face of the quantum threat. According to its members, user assets remain secure today, but the industry should not consider the absence of an immediate threat as a reason to delay its preparation, especially for Bitcoin. In the coming months, debates should therefore focus on migration mechanisms and on balancing security, asset ownership, and network continuity.
