Concord

Blind negotiation and sealed-bid auctions on-chain.

A Solidity protocol for private negotiation and sealed-bid auction workflows, designed to separate commitment from reveal and make settlement rules auditable.

Vision

The premise behind Concord.

Digital negotiation should preserve strategic privacy before settlement while leaving a clear, verifiable outcome afterward. Concord explores that balance through commitment-based market mechanisms.

  • Commit-and-reveal flow for sealed participant intent
  • Auditable settlement logic expressed as smart contracts
  • Clear lifecycle boundaries for bidding and resolution
  • A focused protocol surface for negotiation experiments

Private before resolution

Participants commit to an offer without immediately exposing its contents. A later reveal phase allows the protocol to verify the original commitment and resolve the negotiation fairly.

  • Sealed participant intent
  • Deterministic phase transitions
  • Verifiable reveals

Rules that can be inspected

The auction lifecycle and settlement conditions live in Solidity, making the mechanism explicit and reviewable rather than dependent on an opaque intermediary.

  • On-chain settlement
  • Auditable contract rules
  • Composable protocol foundation
