The CoinShares report that explains why your bitcoins are safe from supercomputers

Digital asset investment firm CoinShares revealed why quantum computing does not pose an immediate threat to Bitcoin.

The digital asset industry has been experiencing growing concern in recent months: the possibility that a supercomputer could break the cryptographic security protecting blockchain networks. However, Technical reality shows that this scenario is far from materializing.

A recent report published by CoinShares offers an updated and reassuring perspective on this topic. According to the analysis, blockchain infrastructure continues to show a strong resistance to current advances in quantum computingwhich means that users' funds remain safe.

According to the report, ideas about the danger that quantum algorithms currently pose to the crypto industry have been exaggerated. CoinShares argues that the decentralized nature of blockchain networks acts as a dynamic barrier, capable of adapting to technological changes and strengthening its own security over time.

Quantum risk remains under control

CoinShares argues that quantum computing poses a potential threat to Bitcoin It is under control and does not pose an immediate risk For the security of the crypto ecosystem. While quantum algorithms like Shor's could, in theory, break the digital signatures used by Bitcoin—based on ECDSA and Schnorr—an attack of that magnitude remains beyond the reach of current technological capabilities. The amount of computing power needed to perform that type of calculation remains unattainable, thus safeguarding the integrity of the network, the firm asserts.

Analysts also explain that the main vulnerability is associated with the public keys used to authorize transactions. Shor's algorithm could solve the mathematical problem protecting elliptic curves and thus expose private keys when they become visible. However, other areas of the Bitcoin protocol remain resilient. Grover's algorithm, for example, only reduces the effective security of SHA-256 symmetric hashes to 128 bits, a level that remains secure, as brute-force attacks continue to be impractical due to the computational cost involved.

Regarding mining, CoinShares experts acknowledge that a quantum computer could process calculations faster than a conventional machine. However, its profitability compared to ASICs is questionable, and furthermore, Bitcoin's automatic difficulty adjustment mechanism neutralizes any temporary advantage. They also emphasize that quantum computing cannot alter the maximum supply of 21 million coins or the proof-of-work system that validates the blocks, so the fundamentals of the blockchain protocol remain intact.

El report It also highlights that the real exposure of the Bitcoin network is concentrated in addresses where public keys are visible, especially in older ones. Pay-to-Public-Key (P2PK) addressesThese contain approximately 1,6 million bitcoins, representing about 8% of the total supply. However, only about 10.200 coins are stored in unspent outputs with sufficient volume to cause a market disruption in the event of a breach. The remainder, distributed across tens of thousands of small addresses, would require a disproportionate effort to crack, even with the most optimistic advances in quantum computing. 

With this, CoinShares concludes that, under these conditions, the risk is manageable and that current security measures offer effective protection to blockchain network users.

Bitcoin: evolution, security and scarcity in the quantum age

Bitcoin's strength lies not only in its current market position but also in its adaptability. CoinShares analysts argue that this resilience stems from a continuous process of technological transformation. Like Michael Saylor, CEO of MicroStrategy, they emphasize that the network's robustness and security continue to grow as its software evolves to meet new challenges, including the potential arrival of quantum computing, considered a key driver of its next phase of development.

Several experts agree that Bitcoin's open-source nature gives it a crucial advantage. Thanks to a global community of developers, the network can anticipate future threats and implement structural improvements before risks materialize. One example of this would be the eventual adoption of cryptographic standards designed to withstand the effects of quantum computing, such as the algorithm Pay to Quantum Resistant HashSuch a transition would involve a large-scale upgrade that would strengthen Bitcoin's core infrastructure and consolidate its long-term security.

However, this technological evolution could also have significant economic consequences. If the network migrates to a post-quantum environment, users would have to move their funds to new, more secure addresses. Those coins that remain on older protocols, such as those linked to inactive wallets or the first mined blocks—including those associated with the network itself—would be at risk. Satoshi Nakamoto— would become inaccessible. Their effective loss would reduce the circulating supply and deepen the scarcity of the asset, which experts like Saylor interpret as a natural purification process within the ecosystem.

The CoinShares report also clarifies that modern addresses, such as Pay-to-Public-Key-Hash (P2PKH) y Pay-to-Script-Hash (P2SH)They already incorporate measures that protect public keys after Hash functions, keeping them secure until the moment of spending. Estimates suggesting a 25% vulnerability should be understood as a temporary risk linked to specific practices, such as the reuse of addresses on exchanges. 

All these scenarios can be avoided with simple behavioral adjustments, and according to analysts, there would be technical warnings for years before real threats emerged, allowing enough time for an orderly transition to a strengthened security model.

The crypto industry is preparing for the future

Besides Bitcoin, other cryptocurrencies like Ethereum are preparing to face post-quantum security with increasingly defined strategies. 

In fact, the Ethereum Foundation has made this goal a central priority. With the creation of specialized teams, including the Post Quantum TeamIt seeks to strengthen the foundations of its network against the threats that could arise with the advancement of quantum computing. 

Researcher Justin Drake explained that the purpose of these efforts is to develop protection mechanisms capable of safeguarding transactions without compromising the efficiency or scalability of the ecosystem. These types of initiatives reflect how leading blockchains not only react to technological changes but also anticipate them, paving the way for a new encryption standard that will define the next digital era.

Meanwhile, analyses by CoinShares and various specialists confirm that the emergence of quantum computing will not bring an end to the world of cryptocurrencies. Rather, it will be a turning point. 

For experts, Bitcoin represents a living system that evolves with each technical challenge and adapts its infrastructure to the needs of the environment. Its design, based on community consensus, facilitates the incorporation of improvements that reduce exposure to vulnerabilities without altering the integrity of the protocol. 

The sum of these factors suggests that quantum technology will not be an existential risk to blockchain technology and digital assets, but rather an opportunity to strengthen their security and consolidate them as one of the most robust and resilient forms of ownership in the 21st century.
