FAIR - Federated Agreement for Independent Resolution: A Cross-Chain Decision-Making Protocol

Abstract

This paper introduces FAIR (Federated Agreement for Independent Resolution), a cross-chain protocol designed to enhance scalability, transparency, and auditability in decentralized decision-making processes. Unlike traditional blockchainbased voting systems that rely on a single global chain, FAIR leverages a federated model in which local decisions are conducted on independent blockchains and subsequently aggregated into a global result through a secure cross-chain mechanism. The protocol employs Soulbound Tokens (SBTs) and Rejectable SBTs (RejSBTs) to ensure verifiability, immutability, and explicit acceptance of results, thereby strengthening both the integrity and security of cross-chain operations. We formalize the protocol, provide smart contract implementations, and illustrate its applicability in diverse contexts such as multinational corporations, district-based elections, and decentralized autonomous organizations. FAIR demonstrates that a federated and tokenized approach to decision-making enables efficient large-scale participation while maintaining strong guarantees of trust, transparency, and robustness.
