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

ChainCatcher news, Paraguay's largest bank Ueno Bank has 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 is based on the QANplatform's quantum-resistant Layer-1 hybrid blockchain, combined with the SignQuantum signature extension, providing mathematically verifiable tamper-proof 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) and offers a replicable model for the financial industry to address the future risks of quantum computing breaches. Industry insiders say this is the world's first bank to deploy such a combination of technologies at a production scale, establishing a "quantum-safe" paradigm for financial institutions in Latin America and globally.
