PQC Security

Post-quantum protection designed into the protocol.

AT A GLANCE

PQC protection with compact consensus data

Verify the signature, then agree on its digest.

  1. Transaction

    PQC-signed transaction

  2. PQC verification

    Validate the signature

  3. CAD / CADRoot

    Verified signature digest

  4. Block header

    Fixed-size digest record

The consensus layer uses a verified digest to limit growth from large PQC signatures.

NIST Standard-Based Quantum Resistance and Block Bloat Prevention via CAD Technology

Proactively responds to the threat of existing cryptographic systems being neutralized by quantum computers' Shor's algorithm. Secures both security and performance by integrating global standard Post-Quantum Cryptography (PQC) into the protocol and suppressing chain bloat caused by large PQC signatures using CAD technology.

Application of NIST Standard Lattice-Based PQC

Introduced the U.S. NIST standard quantum-resistant signature algorithm into the transaction and verification layers, capable of defending against ultra-high-speed computational attacks from quantum computers.

Fundamentally blocks the decryption risk of existing asymmetric keys (ECC, RSA), guaranteeing the permanent integrity of assets and key data requiring long-term preservation.

CAD(Consensus Authorization Digest) Signature Lightweighting

Records a fixed-size signature digest (CAD) in the block header to solve the issue of rapidly increasing on-chain storage caused by PQC signature data, which is significantly larger than conventional cryptography.

Prevents chain bloat by separating the consensus layer so it agrees only on the verified digest (CADRoot) rather than cumulatively storing massive original signatures in the block.

Flexible Identifier Structure Supporting Quantum Transition

Designs a version bit (PQCFork-era) within the SSI (Self Sovereign Identifier) specification to seamlessly distinguish and support legacy and quantum-resistant transition environments at the protocol level.

Provides Crypto-Agility, allowing a gradual transition to a quantum-resistant account system without service interruptions or the chaos of hard forks.

Securing Enterprise Reliability Across the Entire Blockchain Pipeline

Implements a business environment perfectly protected from future Q-Day threats by applying PQC security controls throughout the entire protocol process, from transaction generation and signature verification to block consensus data integrity.
