Thanks to their decentralized, tamper-proof, and self-governing characteristics, smart contracts can ensure the fulfillment of contracts and the smooth progress of transactions without the need for centralized authoritative supervision. The application fields of smart contracts are wide-ranging, including finance, management, healthcare, IoT, and other traditional industries. Through smart contracts, transaction  costs can be reduced, transaction efficiency increased, trust barriers minimized, and more efficient and convenient asset management and circulation achieved."}]}],"pr":"04e22a785c72771bf1a080f3a56157d8b2692f82789e706f78fb87e7f0152c81"}
