The crypto community has sounded the alarm about hypothetical advancements in quantum computers that could in the future be able to break Bitcoin’s cryptography. Some in the space — including Bitcoin developers — have started preparing for a post-quantum future by testing quantum-resistant signatures on live sidechains. Quantum computers do exist but make mistakes and a machine that can break Bitcoin’s cryptography currently does not exist. BlackRock has skin in the game after having debuted in 2024 spot Bitcoin and Ethereum exchange-traded funds. BlackRock boss Larry Fink has also talked of Bitcoin being “digital gold” and an “international asset” and has spoken about how crypto networks can help tokenize everything.
