Google research suggests encryption technique used by Bitcoin will be cracked by quantum computers around 2029 — search giant says quantum attacks need to be prepared for now

Google's research indicates that the encryption technique used by Bitcoin could be cracked by quantum computers around 2029, earlier than previously thought. This could have significant implications for blockchain infrastructure and cryptocurrencies. The attack on elliptic-curve cryptography (ECC) using Shor's algorithm poses a threat to the security of blockchain networks. Google suggests transitioning to Post-Quantum Encryption (PQC) to mitigate this risk, but the decentralized nature of blockchains presents challenges for implementation. Other applications like website key exchange and messaging apps are also transitioning away from ECC to PQC to enhance security against quantum attacks.
