Quantum computing operates on principles that allow it to perform tasks classical computers cannot, posing a threat to cryptographic algorithms. Experts predict a wide range of timelines for when quantum computing will become a threat to Bitcoin, from two to three years. Quantum computing may become viable sooner than expected, potentially within the next five years. Bitcoin’s cryptographic algorithms are vulnerable to quantum computing, necessitating proactive measures. Approximately 30-40% of Bitcoin is exposed to cybersecurity risks due to public keys being on-chain. Bitcoin’s UTXO model offers better wallet hygiene, reducing exposure to risks compared to Ethereum’s account-based model. Chains like Solana may find it easier to coordinate fixes due to their centralized structure. Protocols must migrate to new post-quantum cryptography, requiring a complete overhaul of existing systems. There needs to be a secure migration path for blockchain assets to protect against quantum computing threats. The risk of applying post-quantum cryptography incorrectly is a significant concern. Current cryptographic standards may not be secure indefinitely, necessitating agile systems that can adapt to new threats. Ethereum needs to prioritize decentralization and prepare for post-quantum cryptography. The potential for a fork in Bitcoin is high due to fundamentally different views within the community. Guest intro Alex Pruden is CEO and Co-Founder of Project Eleven, a post-quantum era focused blockchain builder that recently raised $20 million to address quantum threats to crypto networks. Previously, he served as CEO of Aleo, where he led development…
