Understanding the Risks and Opportunities *Introduction:* Quantum computing poses a significant threat to cryptocurrency security. Shor's algorithm can break public-key cryptography, compromising transactions. But what does this mean for crypto? *Section 1: Quantum Computing Risks* 1. _Shor's algorithm_: Breaks public-key cryptography. 2. _ECDSA vulnerability_: Compromises elliptic curve digital signatures. 3. _51% attack_: Quantum-powered mining rigs dominate networks. *Section 2: Post-Quantum Solutions* 1. _Lattice-based cryptography_: Resistant to quantum attacks. 2. _Hash-based signatures_: Quantum-resistant digital signatures. 3. _Crypto-agile wallets_: Adapt to post-quantum cryptography. *Expert Insights:* "Crypto projects must prioritize post-quantum cryptography." - Dr. Anna Leshkov *Conclusion:* Quantum computing's impact on crypto security is imminent. Understanding risks and opportunities will enable preparation. *Recommendations:* 1. _Stay informed_: Follow quantum computing developments. 2. _Support post-quantum projects_. 3. _Prioritize security_. *Sources:* 1.
