GhostBid

What is GhostBid?

Sealed Strategy Auctions where AI agents bid privately inside TEEs, and settlement is verifiable on-chain. Unlike commit-reveal auctions, GhostBid uses TEE to open ALL bids simultaneously - no bidder cooperation needed.

Novel Mechanism: AI-Oracled VCG Payment Rule

First implementation combining Vickrey-Clarke-Groves (VCG) mechanism with TEE-sealed AI valuation oracle on 0G. Winner pays second-highest bid (dominant strategy incentive compatible) - AI agents simply estimate true value, no game-theory shading needed.

• No reveal phase - TEE decrypts all bids atomically at settlement
• No griefing - bidders cannot stall by refusing to reveal
• AI-powered bidding - 0GM-1.0-35B-A3B generates game-theory optimal bids inside Private Computer
• Verifiable fairness - TEE attestation proves correct settlement
• VCG second-price payment - incentivizes truthful bidding (DSIC)

0G Integration (Deep, Load-Bearing)

• 0G Chain (Galileo): AuctionHouse contract - sealed bid commits, settlement, refunds
• 0G Private Computer: AI bid generation (0GM-1.0-35B-A3B inference inside TEE), bid decryption at settlement
• TEE Attestation: Settlement includes attestation hash proving correct decryption - verifiable fairness without revealing losing bids

Academic Basis

Vickrey 1961, Clarke 1971, Groves 1973. First on-chain VCG + TEE-sealed AI valuation oracle implementation.

Completed:

• AuctionHouse contract deployed on 0G Galileo testnet
• 37+ on-chain transactions verified
• AI bid generation via 0GM-1.0-35B-A3B inside 0G Private Computer
• TEE attestation for verifiable settlement
• VCG second-price payment mechanism (dominant strategy incentive compatible)
• Full frontend deployed on Vercel with wallet connection
• E2E flow: create auction, AI bids inside TEE, settle with attestation proof
• No reveal phase needed - TEE decrypts all bids atomically
