Recent research breakthroughs have intensified the debate around Bitcoin’s long-term security, with the Bitcoin Policy Institute warning that advances in quantum computing have shortened the expected timeline for necessary network upgrades. The institute, which focuses on public policy and technical analyses concerning Bitcoin, has released a new report analyzing the implications for the leading <a href="https://en.coin-turk.com/bitcoin-surges-above-86k-brings-hope-to-crypto-enthusiasts/" rel="noopener noreferrer nofollow">cryptocurrency</a>’s cryptographic foundations and the ongoing efforts to address emerging threats.

The Bitcoin Policy Institute’s report draws on two significant research papers published by Google and the California Institute of Technology. These studies challenge previous assumptions regarding the computational resources required to compromise Bitcoin’s encryption, which underpins transaction security across the network.
Traditional estimates placed the number of necessary quantum bits (qubits) at around 10 million for a practical attack using Shor’s algorithm. However, the new analysis contends that the latest discoveries have reduced that needed number to below 500,000 qubits, with some findings from Caltech and the University of California, Berkeley, suggesting it could drop even further to a range of 10,000 to 26,000 qubits for specialized systems.
The two studies took divergent approaches—one prioritizing advancements in software and the other focusing on hardware—but both concluded that the barrier for a potential quantum attack is substantially lower than previously believed. Despite these developments, the Bitcoin Policy Institute emphasized that real-world quantum processors, such as Google’s Willow chip with just over 100 qubits, remain far from the level needed to endanger Bitcoin’s cryptography.
The institute noted that while there is currently no immediate quantum threat to the protocol, these findings press the Bitcoin community to speed up preparations and maintain their focus on long-term security planning.

In response to the emerging risks, Bitcoin developers have prioritized advancing proposals such as BIP-360. The institute describes this initiative as one of the most active areas in the network’s technical work, introducing a new address format that conceals public keys during transactions, thereby reducing vulnerabilities to quantum-based attacks.
A dedicated testnet for these changes launched in March has already seen participation from over 50 miners and upwards of 100 cryptographers, reflecting the community’s proactive stance and technical consensus. The report also points to Bitcoin’s Taproot upgrade, implemented in 2021, which offers flexible features that support the integration of quantum-resistant cryptography as the network evolves.
The debate is also framed within a larger policy context. The National Institute of Standards and Technology unveiled new post-quantum cryptographic standards in 2024, offering a foundation for <a href="https://en.coin-turk.com/arthur-hayes-seizes-market-opportunities-with-swift-crypto-moves/" rel="noopener noreferrer nofollow">cryptocurrencies</a> and federal agencies to enhance future resilience. The U.S. government has assigned a 2035 deadline for its agencies to adopt quantum-safe measures and Google reportedly aims for internal readiness by 2029.
The institute observed that Bitcoin’s decentralized model presents a core challenge, as network upgrades require widespread voluntary adoption. Unlike traditional institutions, developers and miners must reach organic consensus to implement security enhancements.
Nonetheless, historical upgrades suggest that collective action is possible when incentives align across stakeholders. The report concludes that, while the quantum threat is not immediate, attention is shifting toward finding consensus on the path forward and ensuring robust security for the future.
Meanwhile, StarkWare’s Avihu Levy has proposed a new “Quantum Safe Bitcoin” method, aiming to safeguard transactions with hash-based cryptography and keep compatibility with the current network, all without requiring protocol changes.
