Venture capital investor Tim Draper argued in a statement on social media on June 9 that quantum computers pose a more imminent threat to the traditional banking system than Bitcoin. Draper argued that fiat deposits held in banks are more fragile than Bitcoin assets.
Criticisms of banking infrastructure
According to Draper, traditional financial institutions do not operate with a monolithic system. In contrast, it relies on a lot of old and interconnected infrastructure built over decades. This fragmented structure, ranging from customer transactions to interbank reconciliation networks, creates a separate security risk at each point.
Tim Draper stated that quantum computers will break banks long before they reach blockchain, while traditional financial institutions remain more vulnerable due to their old infrastructure.
One of the risk models that stood out in the news was the “collect now, solve later” approach. Cyber attackers can store the encrypted data captured today for a long time and aim to decipher these records when sufficiently powerful quantum systems come into play. This situation may create irreversible consequences, especially for banks; because it may not be possible to completely protect data once copied.
Mini dictionary: Collect now, decode later approach refers to storing encrypted data that cannot be broken today in order to be decrypted with stronger systems in the future. In quantum threat discussions, this method is seen as a significant risk, especially for financial and corporate data that must remain confidential for a long time.
Draper said Bitcoin has a different architecture here. He argued that since transactions in the Bitcoin network are kept on an open ledger, there are no secret data stores like in banks, which eliminates one of the main quantum-based attack surfaces. As an investor known for his pro-Bitcoin outbursts for a long time, Draper had previously reiterated his $ 250,000 prediction for Bitcoin.
Prominent difficulties on the Bitcoin side
Draper suggested that even in the worst-case scenario, the Bitcoin network has the opportunity to recover. He stated that participants operating full nodes keep a full copy of the blockchain, so the network can be returned to the last block deemed secure.
Draper stated that even if there is a problem in the blockchain, full node operators can return the network to the last secure block and the network can continue to operate.
However, security experts emphasize that this approach is not easy to implement. Casa’s Director of Security, Jameson Lopp, warned that it could take around 10 years for the Bitcoin network to transition to quantum-resistant cryptography. Casa is known as a company that offers custody and security solutions to Bitcoin users.
The news also pointed out that the main difference between banks and Bitcoin is in the governance model. Banks can apply security updates more quickly under the direction of regulators. In Bitcoin, consensus must be reached on a global scale between developers, miners and node operators. For this reason, the absence of a central decision-making mechanism, on the one hand, stands out as the basic principle of the system, and on the other hand, it is considered as an element that can slow down technical transformations.
Official institutions started to determine the calendar
The US National Security Agency was also among the institutions that took steps to transition to quantum-resistant technologies. It was reported that the agency wants these technologies to be adopted in national security systems by January 2027. Although this calendar does not directly cover all financial institutions, it shows that public authorities are taking the issue seriously.
It is not yet clear whether banks can make the necessary updates within critical periods and how quickly the Bitcoin community can achieve a similar scale of consensus. The discussion reveals that the potential impact of quantum computers is not limited to crypto assets, but is addressed as a broader financial infrastructure issue.
