According to @cas_abbe, Algorand has executed live quantum-secure transactions on mainnet, confirming real-world deployment rather than a roadmap item, which is directly relevant to ALGO fundamental analysis and security-driven trading theses, source: Cas Abbé (X post, Dec 9, 2025). The source states Algorand protects chain history with quantum-secure signatures and now supports creating new accounts and transactions in a quantum‑resistant way, source: Cas Abbé (X post, Dec 9, 2025). Falcon is identified as the selected post‑quantum digital signature standard by NIST, reinforcing the credibility of the chosen primitive for Algorand’s implementation, source: NIST Post‑Quantum Cryptography standardization program. The source characterizes Algorand as ahead of other chains on quantum security, positioning ALGO with a distinct security narrative that traders can factor into comparative chain analysis, source: Cas Abbé (X post, Dec 9, 2025).
