Trending Now - Google Warns Quantum Computers Could Soon Threaten Bitcoin Security
WHO:
NewsBTC - Google’s Quantum AI team published a whitepaper and blog post regarding quantum computing threats to cryptocurrencies.
Cointelegraph - Google is the organization updating estimates on quantum computing resources.
WHAT:
CoinDesk - Google’s research indicates that a quantum computer could crack Bitcoin private keys in about 9 minutes once a transaction exposes a public key, giving an attacker a 41% chance of beating Bitcoin's 10-minute confirmation window.
CoinDesk - The paper estimates that approximately 6.9 million Bitcoin, about one-third of the total supply, are in wallets where public keys have already been exposed.
CoinDesk - Google claims that quantum computers could break Bitcoin and Ethereum's cryptography with fewer than 500,000 physical qubits and roughly 1,200 logical qubits, a significant decrease from previous estimates of "millions."
CoinDesk - The research indicates that a quantum adversary could potentially steal Bitcoin mid-transaction in about 9 minutes, with a 41% chance of beating Bitcoin’s 10-minute block time.
CoinDesk - Approximately one-third of Bitcoin's supply is now modeled as potentially quantum-exposed over a long enough horizon.
CoinDesk - Google estimates that quantum circuits can be executed on a superconducting qubit CRQC with fewer than 500,000 physical qubits in a few minutes, based on standard assumptions about hardware capabilities consistent with some of Google’s flagship quantum processors.
CoinDesk - The research indicates a 20-fold reduction in the number of physical qubits required to solve ECDLP-256, now estimated at fewer than 500,000 physical qubits.
CoinDesk - A quantum adversary could potentially steal Bitcoin mid-transaction in about 9 minutes, with a 41% chance of beating Bitcoin’s 10-minute block time.
CoinDesk - Approximately 6.9 million BTC are now considered quantum-exposed due to the Taproot upgrade, which started exposing public keys on-chain by default.

(UPDATED April 1, 2026 09:18 UTC)
Google's recent research reveals that a quantum computer could crack Bitcoin private keys in about nine minutes, posing a significant threat as approximately 6.9 million Bitcoin, or one-third of the total supply, are in wallets with exposed public keys. The study indicates that a quantum adversary could potentially steal Bitcoin mid-transaction, with a 41% chance of beating Bitcoin's ten-minute confirmation window, and suggests that fewer than 500,000 physical qubits are now needed to break the cryptography of both Bitcoin and Ethereum. As a response to these findings, Google has set 2029 as an internal deadline for post-quantum migration, emphasizing the urgency for developers to address these quantum threats to ensure the security of digital currencies.

Google's recent whitepaper reveals that a quantum computer could crack Bitcoin's private keys in about nine minutes, posing a significant risk as approximately 6.9 million Bitcoin, or one-third of the total supply, are in wallets with exposed public keys. The research indicates that fewer than 500,000 physical qubits are now needed to break Bitcoin and Ethereum's cryptography, a drastic reduction from previous estimates, and Google has set 2029 as an internal deadline for transitioning to post-quantum security measures. Analysts warn that unless Bitcoin developers address these quantum threats, the cryptocurrency may struggle to reach new record highs.

A new whitepaper from Google reveals that a quantum computer could potentially crack Bitcoin private keys in about nine minutes, posing a significant threat to the cryptocurrency's security. The paper estimates that around 6.9 million Bitcoin, which is roughly one-third of the total supply, are stored in wallets with already exposed public keys, and it notes a dramatic reduction in the number of physical qubits needed to break the encryption. Google has set an internal deadline of 2029 for post-quantum migration, raising concerns among analysts who warn that Bitcoin's price may struggle to reach new record highs if developers do not address these quantum threats.

(UPDATED March 31, 2026 19:20 UTC)
Google has revealed that quantum computers could potentially break the cryptography of Bitcoin and Ethereum with significantly fewer qubits than previously thought, estimating that fewer than 500,000 physical qubits and around 1,200 logical qubits could do the job. Their research suggests that a quantum adversary could steal Bitcoin mid-transaction in about nine minutes, with a 41% chance of outpacing Bitcoin’s ten-minute block time, and they estimate that roughly one-third of Bitcoin's supply is now at risk of being quantum-exposed. Additionally, the Taproot upgrade has increased the number of quantum-exposed coins to about 6.9 million BTC, prompting Google to set 2029 as an internal deadline for post-quantum migration.

Google has revealed that a quantum adversary could potentially steal Bitcoin mid-transaction in about nine minutes, with a 41% chance of outpacing Bitcoin's ten-minute block time. Their research also shows a significant reduction in the number of physical qubits needed to solve ECDLP-256, now estimated at fewer than 500,000 qubits, while approximately 6.9 million BTC are considered quantum-exposed due to the recent Taproot upgrade. Additionally, Google has set an internal deadline of 2029 for post-quantum migration, which accelerates the timeline for what they refer to as "Q-day."

Google has announced that it estimates quantum circuits can be executed on a superconducting qubit CRQC with fewer than 500,000 physical qubits in just a few minutes, based on their advanced hardware capabilities. The tech giant has set an internal deadline of 2029 for post-quantum migration, which has raised concerns about approximately one-third of Bitcoin's supply being potentially exposed to quantum threats. Analysts warn that if Bitcoin developers do not address these quantum risks, it may be challenging for Bitcoin's price to reach new record highs.

Google's Quantum AI team has published a whitepaper and blog post detailing the potential threats that quantum computing poses to cryptocurrencies like Bitcoin and Ethereum. The research claims that with fewer than 500,000 physical qubits, a quantum adversary could break the cryptography protecting these currencies, potentially stealing Bitcoin mid-transaction in about nine minutes, especially as around 6.9 million BTC are now considered quantum-exposed due to the Taproot upgrade. Google has set an internal deadline of 2029 for post-quantum migration, highlighting the urgency of addressing these vulnerabilities in public-key cryptography.
