Coinbase launches expert board to assess quantum computing threatBy Jeff John RobertsJeff John RobertsEditor, Finance and CryptoDown Arrow Button IconBy Jeff John RobertsJeff John RobertsEditor, Finance and CryptoDown Arrow Button IconJanuary 21, 2026, 4:15 PM ETAdd us onBitcoin is one of the world’s most battle-tested pieces of software. Launched in early 2009, the network has run continuously without being hacked, and today feels more secure than ever. There is, however, a threat on the medium-term horizon that threatens not only Bitcoin but every other type of software that relies on current encryption technology. That threat is quantum computing and, on Wednesday, Coinbase announced it has created a board of outside experts to prepare for its eventual arrival. The board includes academics from Stanford, Harvard, and the University of California with specialties in fields like computer science, cryptography and fintech. Formally known as the Coinbase Independent Advisory Board on Quantum Computing and Blockchain, it is also composed of experts in blockchain and security from the Ethereum Foundation, the DeFi platform EigenLayer and from Coinbase itself. In an interview with Fortune, Coinbase Chief Information Security Officer Jeff Lunglhofer explained how the arrival of quantum computing could defeat current encryption mechanisms, including the ones employed to protect the wallets and private keys held by Bitcoin owners. “In simple terms, modern cryptography relies on hard math problems that would take thousands of years for a modern computer to solve,” he said. “But when we have a million times the horsepower [with quantum computing], that will provide the computation power to solve them.” While the security threat of quantum computing is real, it is unlikely to be an urgent issue for at least a decade, according to Lunglhofer. His view is consistent with other experts who note that, while companies like Google and IBM have been building quantum computers for years, the current generation of these machines can only operate at a small scale and are not close to being able to crack the algorithms that protect Bitcoin and other networks. The purpose of the new Advisory Board, says Lunglhofer, is to explore the coming impact of quantum computing in a “non-hype based way.” This will include promoting efforts by the blockchain industry, which are already underway, to update Bitcoin and other networks so that they are resistant to quantum-based attacks. Currently, the Bitcoin network secures wallets by means of private keys, which are long strings of random numbers and letters that are visible to their owners, but that can only be guessed by means of an impossibly long series of trial-and-error attempts. When the quantum computing era arrives, it will be possible to guess a private key using trial-and-error. In response, Lunglhofer says, blockchain experts anticipate that Bitcoin and other networks will respond by creating larger keys and, at the same time, introducing “noise” to make the location of the key harder to detect in the first place. All of this will require blockchain networks to introduce and deploy these defensive upgrades, a process that is likely to take years. In the interim, the new Advisory Board will begin publishing research papers and issuing position statements to help the crypto industry prepare for the arrival of quantum computing. The group plans to publish its first paper, which will focus on quantum’s impact on the consensus and transaction layers of blockchain, in the next month or two. “Quantum computing is both a technological opportunity and a security challenge. By bringing together the foremost experts in the world, Coinbase is ensuring that the blockchain ecosystem is prepared, not just reactive,” said Yehuda Lindell, Head of Cryptography at Coinbase, in a statement.
