📝 Abstract
Private bidding is a process in which participants submit sealed bids, ensuring that their content remains hidden from other bidders during the bidding window. This is essential in competitive environments to ensure a fair and independent evaluation of all proposals. While (public) blockchain enables decentralized bidding and its transparency offers advantages such as public verifiability, without a Trusted Third Party (TTP), current methods struggle to verify whether a bidder is eligible. We propose a framework that leverages Self-Sovereign Identity (SSI) to address these issues by certifying the bid's eligibility and authenticity using the now-established SSI framework. To allow participants to prove they meet the requirements while keeping their bids secret, our model uses Verifiable Credentials (VCs) and cryptographic primitives such as Zero-Knowledge Proofs (ZKPs).
