IBE-IBE: Intent-Based Execution through Identity-Based Encryption and Auctions
Abstract
This paper introduces a decentralized and leaderless sealed bid auction model for dynamic pricing of intents across blockchain networks. We leverage Multi-Party Computation (MPC) and Identity-Based Encryption (IBE) to improve pricing while ensuring fairness and decentralization. By addressing the vulnerabilities of current centralized or static pricing mechanisms, our approach fosters transparent, secure, and competitive price discovery. We further enhance the confidentiality of intents through Multi-Party Computation (MPC), Fully Homomorphic Encryption (FHE), and Trusted Execution Environments (TEE). Our novel methodology mitigates the risks of frontrunning and centralization while preserving the rapid settlement times essential to decentralized finance (DeFi).
