Meet in the Park: Post-Quantum Messaging
We don't just consult on post-quantum cryptography—we build production systems. Meet in the Park is our quantum-safe messaging application implementing NIST-approved ML-KEM-1024 and ML-DSA-87 algorithms in a real-world product.
From cryptographic implementation to security audits, this project demonstrates our end-to-end capability in deploying post-quantum blockchain solutions. The app has been independently security audited and is currently available for beta testing on Android.
Frequently Asked Questions
Common questions about post-quantum blockchain and our services.
What is post-quantum blockchain?
Post-quantum blockchain refers to blockchain systems that use quantum-resistant cryptographic algorithms to protect against attacks from quantum computers. This includes implementing NIST-approved algorithms like ML-KEM and ML-DSA to secure blockchain networks and digital assets against future quantum threats.
When should I migrate to post-quantum cryptography?
Organizations should begin planning post-quantum cryptography migration now. While large-scale quantum computers aren't yet available, the "harvest now, decrypt later" threat means sensitive data encrypted today could be vulnerable in the future. NIST recommends beginning migration planning by 2025-2030 for most organizations.
What services does BlockSphere provide?
BlockSphere provides two core service areas: (1) Post-Quantum Cryptography consulting including cryptographic risk assessment, migration planning, and implementation support using NIST-approved algorithms, and (2) Blockchain & Web3 development including smart contract development, security audits, and enterprise blockchain integration.
What is the "harvest now, decrypt later" threat?
The "harvest now, decrypt later" (HNDL) threat refers to adversaries collecting encrypted data today with the intention of decrypting it once quantum computers become powerful enough. This means sensitive data with long-term value, such as financial records, health data, or trade secrets, may be at risk even before quantum computers are widely available.
