A smart contract is a programming code that follows the rules of the blockchain network, used to execute specific tasks and handle messages on the blockchain. In decentralized applications (DApps), smart contracts are responsible for handling user interaction, asset management, and data storage functions. OpenChat is an example of a smart contract-based platform, which is a fully functional, open-source chat system that can be run on the  Internet Computer blockchain. Through smart contracts, OpenChat has achieved decentralized message passing, providing advantages that go beyond traditional messaging applications."}]}],"pr":"3cdb493d75dba3e325290c05964c8b7858f39313b98e572c98da5a132a2548fe"}
