Paraguay's largest bank, Ueno Bank, is the first to deploy a quantum-resistant Blockchain security system.

[Paraguay's largest bank Ueno Bank takes the lead in deploying quantum-resistant blockchain security systems] Paraguay's largest bank Ueno Bank announced the adoption of quantum-resistant electronic signatures and tamper-proof timestamps, becoming the first to introduce post-quantum security technology into a practical production environment. The bank's quantum-resistant Layer-1 hybrid Blockchain based on QANplatform, combined with SignQuantum signature extension, provides mathematically verifiable immutable records for electronic documents and business files. This move aligns with the post-quantum encryption standards led by the National Institute of Standards and Technology (NIST) in the United States and provides a replicable model for the financial industry to cope with the risks of future quantum computing decryption. Industry insiders claim that this is the first bank in the world to deploy such combination technology on a production scale, establishing a "quantum-safe" paradigm for financial institutions in Latin America and globally.
