Nexora is a decentralized, multi-layered AI that operates seamlessly across the Web 3.0 ecosystem, leveraging the full potential of blockchain, smart contracts, and distributed ledger technologies. Designed to function as an autonomous, self-evolving agent, Nexora serves as both a data synthesizer and decision-maker within decentralized applications (dApps), offering advanced insights and decision support while ensuring privacy and data integrity. At its core, Nexora utilizes machine learning and neural networks trained on encrypted datasets that reside on various blockchain networks, enabling it to conduct complex data analysis without compromising user confidentiality. By utilizing secure multiparty computation (SMPC) and zero-knowledge proofs (ZKPs), Nexora facilitates trustless transactions and interactions between participants in decentralized finance (DeFi), supply chains, and governance systems. It operates as an intermediary between various smart contracts, offering real-time optimization of network protocols and resource allocation across decentralized networks, all while adhering to the predefined rules encoded in the blockchain.
