Coinbase creates expert council to protect blockchain from future quantum threats

Although quantum computing has not yet reached a stage capable of breaking current cryptographic protections, its eventual development poses a significant long-term threat to blockchain networks and financial systems. Updating networks such as Bitcoin and Ethereum to withstand such attacks will require years of coordinated planning and implementation. Recognizing the potential impact, Coinbase created an independent advisory board to assess the risks posed by this technology and develop strategies to protect blockchain infrastructure before it becomes practically viable.

Strengthening blockchain security for the quantum era

Coinbase points out that the main blockchains, including Bitcoin and Ethereum, are today based on elliptic curve cryptography, a system considered secure given current computing capabilities. But future advances in quantum computing could challenge this model and reveal vulnerabilities. To address this, the company believes that anticipated and coordinated action is essential, combining cryptographic research, multidisciplinary expertise and long-term strategic planning in order to preserve the resilience of blockchain networks as quantum technology advances.

With this in mind, a Coinbase spokesperson told Decrypt that the company is establishing the advisory board to encourage early planning within the blockchain ecosystem, support rigorous assessment of emerging evidence, and align practical measures aimed at maintaining the long-term resilience of blockchain infrastructure.

Expert panel guides blockchain readiness

The council brings together leading experts from academia and the crypto industry to provide guidance and ensure the application of diverse expertise to these complex challenges. Its members include Dahlia Malkhi, head of the Foundations of Fintech Research lab at UCSB; Justin Drake, researcher at the Ethereum Foundation; Sreeram Kannan, founder of EigenLayer; Scott Aaronson, quantum computing expert; Dan Boneh, cryptography leader at Stanford; and Yehuda Lindell, head of crypto at Coinbase.

Among board members, Scott Aaronson noted that the timeline for quantum computers to reach a level capable of compromising public key cryptography remains uncertain, which can extend over several years or even decades. He added that “What is clear is that we must already be thinking about the transition to post-quantum cryptosystems, and that we must have the ability to react to future events as they arise.“

Board objectives, expert analysis and quantum preparation

Coinbase intends for the council to play an active role in preparing blockchain networks by:

• Creating detailed reports which examine how quantum computing could affect blockchain systems and highlight key developments in this area.
• Offering practical advice to developers and organizations to strengthen defenses against potential quantum threats.
• Providing timely analysis and practical advice in response to major advances in quantum technology.

This initiative was welcomed by industry experts. Anastasia Marchenkova, a quantum researcher and advisor at BTQ, noted that Coinbase's initiative addresses growing questions about its approach to quantum computing. She noted that early engagement with quantum risks is essential for the lasting security of cryptocurrencies and that Coinbase's decision to publicly address these challenges is of particular importance in the crypto industry and beyond, particularly as banks and other financial infrastructures begin to incorporate potential quantum threats into their security strategies.

Beyond Coinbase, blockchain teams are actively developing new security measures intended to protect networks from potential quantum threats, gradually updating their systems to maintain stability. Ethereum co-founder Vitalik Buterin recommends introducing quantum-resistant cryptography early, well before quantum computing poses a real risk, while Cardano founder Charles Hoskinson warns against moving too quickly without sufficient hardware support that could affect network performance.
