BlackRock, the largest asset management firm globally, has recently shared its perspective on the ongoing conversation regarding crypto and quantum computing—expressing unexpected optimism.
In its latest publication, Quantum Computing and Blockchains, the firm, which oversees more than $15 trillion in assets, stated that transitioning current cryptographic methods to be quantum-resistant is significantly simpler than developing a capable quantum computer that could compromise existing encryption.
“From our perspective, the migration to post-quantum standards for cryptocurrencies is feasible from a technical viewpoint; however, the real challenge lies in effective coordination and execution within the community,” the report indicated.
Members of the crypto community are voicing concerns regarding potential future advancements in quantum computing that may threaten Bitcoin’s encryption. Some developers have already begun efforts to prepare for a world beyond quantum threats by experimenting with quantum-resistant signatures on active sidechains.
While quantum computers are in existence, they currently make errors, and a machine that can effectively breach Bitcoin’s cryptography has yet to be developed. Presently, Bitcoin represents the most extensive computing network available.
BlackRock has invested in this domain, having launched Bitcoin and Ethereum exchange-traded funds (ETFs) in 2024. Their Bitcoin fund achieved the most successful debut in ETF history.
CEO Larry Fink has described Bitcoin as “digital gold” and an “international asset,” emphasizing how cryptocurrencies could facilitate the tokenization of various assets.

Insights from BlackRock on Bitcoin
The report elaborated that while technical solutions are available to safeguard Bitcoin from quantum threats, the challenge of coordination remains due to the cryptocurrency’s decentralized and consensus-oriented nature.
BlackRock added that approximately 35% of the circulating Bitcoin supply might be at risk from specific attack vectors due to exposed public keys, and between 11% to 19% could be irretrievably lost, regardless of any migration measures.
Alongside major players like Coinbase, Fidelity Digital Assets, and Block, BlackRock announced a Bitcoin Security Consortium focused on providing funding to engineers for their open-source contributions, particularly regarding proposals like BIP-360.
Though BlackRock acknowledged BIP-360 as a credible component of a larger solution, it did not label it as the final answer. The firm maintains that Bitcoin and other cryptocurrencies hold a distinct potential advantage.
“In conclusion, upgrading existing cryptographic frameworks (including those for Bitcoin, Ethereum, and others) to quantum-safe standards is certainly less complex than constructing a capable quantum computer, given the current stage of quantum computing advancements,” the report asserts.
“Therefore, the defensive position retains a significant edge at this moment.”
