zk-FIDNA : Zero-knowledge proof based on zk-SNARKs applying omega protocol

Introduction
zk-FIDNA is a Layer 2 technology that leverages zk-SNARKs for zero-knowledge proof-based digital signatures to validate transaction data on the distributed ledger. Our cryptography research team refers to the integrated technology combining zk-FIDNA and EHETL as Privy Encryption.

• Properties of EHETL
• Perform transaction data validity checks.
• Integration with ECHC encryption.
• Ensure security strength using the omega protocol.

Fourchains cryptography research team developed a digital signature-based commitment using the Elliptic curve Homomorphic Digital Signature Algorithm (EHDSA) from our previous studies and developed the omegaProtocol, which extends the concept of polynomials to linear forms. Additionally, to further enhance the meaning of confidentiality, we adopted the concept of Anonymous Zether and named it zk-FIDNA, where FIDNA stands for Flexible Integrity Digital signature-based Non-Interactive Arguments.
