Every bid is encrypted using Arcium's Multi-Party Computation (MPC) network before it is submitted to Solana. The bid value is split across multiple independent Arcium nodes — no single node ever holds the complete value. Only when the auction closes do the nodes jointly compute the result, revealing only the winner and clearing price.

A Vickrey auction is a sealed-bid format where the highest bidder wins but pays the second-highest price. This incentivizes bidders to bid their true valuation rather than strategically underbidding. It's considered the gold standard for fair price discovery and is widely used in economics and mechanism design.

No. Your bid is encrypted by Arcium's MPC before it is ever written to the blockchain. What validators see is an encrypted commitment — a cryptographic hash with no readable value. Even if a validator tried to front-run your transaction, they would have nothing to act on.

Arcium's MPC protocol is designed with fault tolerance. The network uses threshold cryptography, meaning a minimum threshold of nodes must participate in decryption — but a single offline node cannot halt the auction. The protocol continues as long as the threshold is met.

BlindBid currently supports three sealed-bid formats: Vickrey (second-price), First-Price (highest bid wins and pays their bid), and Uniform-Price (used for multi-unit auctions where all winners pay the same clearing price). More formats are on the roadmap.

Yes. The smart contracts, Arcium integration layer, and frontend are all open source and available on GitHub. Anyone can audit the code, verify the cryptographic implementation, or fork the protocol for their own use.

BlindBid is currently live on Solana Devnet for testing and demonstration. Mainnet deployment is planned following a full security audit of the smart contracts and Arcium integration.
