Confidential Auctions
Confidential Auctions
Onchain auctions, ranging from traditional bids to NFT marketplace offerings, DeFi liquidations, governance decisions, and token sales, can significantly benefit from Fhenix’s confidential smart contracts. These contracts allow users to place encrypted bids, maintaining anonymity and fairness without exposing personal data or sensitive bid details. Upon the auction’s closure, only the winning bids are disclosed, an approach especially valuable for high-stake or sensitive transactions involving premium items or significant financial decisions.
Key Components:
Encrypted Bids: Bids are encrypted to ensure confidentiality and prevent exposure during the auction process. Even though bids are encrypted, the process must be transparent and verifiable to ensure that the auction is conducted fairly.
Smart Contracts: Automate the auction process, including bid submission, validation, and winner selection, while maintaining confidentiality.
Reveal Mechanism: A secure decryption method to unveil winning bids at the auction’s conclusion without compromising the integrity of the process.
Privacy-Preserving Protocols: Ensure that participants’ identities and bid amounts remain confidential throughout the auction.
Why is Encryption/
Confidentiality required?
Protecting Bidder Privacy
Encryption ensures that bid amounts and the identity of bidders remain confidential throughout the auction. This protects bidders from being targeted outside the auction environment or having competitive bids made based on their identity.
Maintaining Fairness
& Integrity
Confidentiality helps in preserving the integrity of the auction process. If bid details were publicly accessible, it could lead to front-running, collusion, or other forms of auction manipulation. Encryption ensures that all bids remain secret until the auction concludes, maintaining a level playing field for all participants.

Ensuring Regulatory Compliance
In some jurisdictions, there are strict privacy and data protection laws that require the confidentiality of personal and financial data. Encryption in onchain auctions ensures compliance with these regulations, avoiding legal repercussions for both auctioneers and bidders.
Why Fhenix?
Traditional auctions, NFT marketplaces, DeFi liquidations, and other types of onchain transactions require confidentiality to protect data and ensure complete fairness. By leveraging Fully Homomorphic Encryption (FHE) technology into auctions, it’s possible to protect bidder privacy, maintain complete fairness and integrity, and ensure regulatory compliance, all onchain and completely decentralized.
Complete Privacy Preservation: FHE enables computations on encrypted data without ever decrypting it, ensuring complete privacy preservation. Unlike TEE, where data is decrypted within a secure enclave, FHE keeps data encrypted at all stages, reducing exposure to unauthorized access or leaks.
Universal Computations & Broad Potential Applications: FHE stands out for its ability to execute virtually any computation on encrypted data, providing a universal solution for all possible confidential auction requirements. This also means that FHE can be utilized across a broader range of applications, enabling more complex and privacy-preserving applications. In contrast, existing technologies like MPC and ZK are often designed for specific types of computations or applications.
No Trusted Third Parties: Both TEEs and MPC technologies may require trusted third parties or trust setup procedures. FHE operates without needing trusted third parties, increasing security and enabling fully decentralized auctions.
Non-Interactive: Many encryption schemas such as MPC are interactive, meaning they require coordination amongst parties. This introduces complexity and inefficiencies, whereas FHE’s non-interactive nature ensures computations are streamlined.
Simplified Infrastructure: MPC requires coordination amongst multiple parties, while TEE requires extremely specialized hardware. In contrast, FHE greatly simplifies the infrastructure requirements for secure computations.
Enhanced Regulatory Compliance: With stringent data protection laws, FHE’s robust privacy-preserving feature can aid in data privacy and compliance, especially critical for onchain auctions.
