Cryptographic Mechanics

Realistic Privacy & Bidding Mechanics

Sealed decouples financial strategy from market visibility. Bidders prove solvency and lock commitments without leaking price ceilings to competitors.

1. Client-Side Solvency Check

Before entering an auction, a local ZK circuit verifies that your supported stablecoin balance satisfies the bid condition on-device, without broadcasting total net worth.

2. Hidden Commitment Escrow

Bids are hashed and locked into escrow during the active auction window. Market observers see that a commitment exists, but zero price or wallet identity data is leaked.

3. Reveal-at-Close Settlement

At auction expiry, bid amounts are revealed to calculate the highest bidder deterministically. Losing bidders then claim a full refund with a claim transaction.

Engineering Note: Honest Privacy Guarantees

The protocol uses Reveal-at-Close to guarantee verifiability without requiring a trusted intermediary. Full blind settlement via Threshold MPC is slated for future protocol iterations once distributed liveness proofs mature.

Jurisdiction-Agnostic Execution

Pluggable Logistics & Local Partners

Sealed delegates offline verification and physical delivery to accredited regional partners, keeping software infrastructure lean and legally scalable.

Mobile High-Value Goods

Handled through double-blind courier protocols (encrypted waybills with separated pickup/drop-off tokens). Integrated with regional and global couriers (DHL, local logistics partners).

Configurable Verification Holding Window (e.g. 24h)

Global Authentication Partners (Real Authentication, etc.)

Immobile Real Estate & Land

Bidding and discovery stay private until close. Legal transfer is executed by accredited local professionals (RICS in UK, NIESV/ESVARBON in NG, state-licensed appraisers in US).

Configurable Commitment Stake (e.g. 10%)

Automated Stake Slasher for Failure to Close

Multi-Country Onboarding: Launching in new regions requires configuring local stablecoin liquidity, local accredited surveyor rails, and legal compliance review.
