They are based on the Ethereum platform and use Ether as fuel. Unlike traditional contracts, smart contracts eliminate the possibility of intermediary  participation, thereby improving transaction efficiency and security. Smart contracts have a wide range of applications, including finance, logistics, insurance, gaming, and more. Through smart contracts, we can develop decentralized applications (DApps) to provide users with more convenient and secure services."}]}],"pr":"cc98de65c1339729b3a429722c8cb52456cffe7b7a7dc82aa2a5f5065a0a2ac5"}
