As quantum computing advances, experts warn about the threats to modern blockchain systems like Bitcoin and Ethereum. The primary dangers are related to the potential for decrypting encrypted data.
The Threat of Quantum Computing
The CEO of Naoris urges attention to the threats posed by quantum technologies, asserting that most blockchain networks rely on cryptography that could become obsolete with new quantum breakthroughs.
The 'Harvest Now, Decrypt Later' Tactic
Carvalho stresses that while the industry views the threat as a distant future, attackers are already harvesting encrypted data in hopes of decrypting it later with quantum tools.
Security Recommendations and Conclusion
Despite various initiatives like post-quantum key formats, adoption remains slow. Carvalho notes that real-world infrastructure remains vulnerable, including cloud nodes and centralized systems, regardless of how decentralized blockchain protocols claim to be.
Quantum computing presents a serious threat to existing blockchain systems. The industry must urgently find solutions to enhance security and protect against such attacks.
