Designed for banks. Built for what's next.

The challenge is twofold. They must defend against a redefined threat landscape shaped by quantum computing -- while adapting to a rapidly decentralizing digital world.

CryptoCode is built for this transition.

Encrypted from end to end. Fully owned by the bank.

CryptoCode is deployed as a dedicated, bank-operated system. Banks retain complete control over the software and infrastructure, eliminating the need for data sharing with third parties and significantly reducing risk. Whether they opt to utilize their existing network or build a new one with us, the bank will own the entire system and retain full copyrights. This model empowers banks to implement their own policies and customize parameters to meet regulatory compliance, ensuring seamless transition into decentralized world.

Designed for real-world deployment, our system supports high-performance encrypted computations, seamless integration with existing infrastructure, and a modular design to accommodate future upgrades and evolving integration needs.

Key Benefits:

• Long-Term Security with Post-Quantum Cryptography (PQC) to safeguard against emerging quantum threats.
• Adjustable Privacy is made possible by Fully Homomorphic Encryption (FHE) and offers customizable confidentiality to align with specific operational and regulatory needs.
• Advanced Zero-Knowledge Protocols deliver verifiable accuracy—without ever revealing sensitive data.
• High-Speed Cryptography designed for speed and scale.

Private Decentralized Network Architecture

The system runs on a private decentralized network operated by the bank(s) or a consortium of trusted parties. It offers:

• Full node control by the bank
• Policy-driven governance
• Integration with the bank’s existing digital infrastructure

Confidential Account Model

Balances are stored in an encrypted accounts. All transactions modify the account balances without decryption:

• User A encrypts the amount to be sent
• Generates a transaction including ZK proofs of validity
• Broadcasts the encrypted transaction
• Validators check the proofs, update encrypted balances
• No party (except the bank) can decrypt transaction content

Bank-Controlled Key Management

• The bank (or the consortium) is the trusted authority
• Encryption and signature keys are established and managed by the bank
• The bank has exclusive decryption rights -- ensuring auditability and regulatory compliance
• Customers interact pseudonymously (via public keys) on the network

Designed for Regulatory Compliance

Our system is built to support and enforce banking policy requirements, including:

• Auditable access: banks can decrypt any transaction if needed
• Custom rulesets: institutions can define validation logic and data retention policies
• Data visibility boundaries: transactions remain confidential to users and visible only to the bank
• Encrypted records: data at rest and in motion is always encrypted

This gives banks the flexibility to meet both national regulations and internal audit standards -- without compromising on confidentiality or future readiness.

Proven Building Blocks

• Successfully deployed in a prior (non-PQ) system used by an overseas banking consortium
• While existing solutions are constrained to either 32-bit or 64-bit encryption, our system operates without such limitations, offering flexible and robust support across the spectrum.
• Now combining FHE + ZK with practical performance targets for institutional use

Fully Homomorphic Encryption

At the core of our platform is the BFV encryption scheme, enabling all operations to be performed directly on encrypted data.

• Post-quantum secure (lattice-based cryptography)
• No decryption needed during computation
• Supports plaintext of any length, ensuring seamless handling of real-world financial amounts while maintaining optimal efficiency

Our implementation already supports efficient encrypted value processing with performance suitable for enterprise-scale applications.
