SmartLLM: A New Oracle System for Smart Contracts Calling Large Language Models

Trustworthy oracles are an essential component of blockchain technology, providing a mechanism for blockchain applications to access data from the real world and verify it on-chain. With the continuous development of blockchain technology, trustworthy oracles have become one of the hot research topics in the blockchain industry. This article reviews the current research status and challenges of trustworthy oracles, summarizing the major research progress in the oracle field in recent years from aspects such as architecture and key technologies. Based on this, we propose a system architecture called SmartLLM that allows smart contracts to call large language models based on a trustworthy oracle mechanism. There are two types of architectures: one is chain-native, and the other is a combination of on-chain and off-chain. This architecture provides technical support for smart contracts to use large language models, enriching the use cases of smart contracts.
