Holding a Chair in Applied Theoretical Physics at the University of Athens, I dedicate my research to Post-Quantum Cryptography (PQC). My work addresses the inevitable moment when quantum computing architectures running Shor’s algorithm render standard elliptic-curve blockchain encryption completely obsolete. I work exclusively with Layer-1 consensus architects and high-value treasury protocols. I audit underlying signature schemes and upgrade standard secp256k1 cryptographic handshakes to quantum-resistant, lattice-based mathematical standards like CRYSTALS-Dilithium and Falcon hash algorithms. Due to my academic commitments, I accept strictly one marketplace advisory contract per month. Fulfilling a contract with me guarantees that your blockchain protocol’s cryptographic vaults remain secure against next-generation decryption vectors for the next twenty-five years.
