A blockchain-based data processing method, apparatus and storage medium provides flexible smart contract deployment without restarting. In response to receiving a contract deployment request sent from a requesting node in a blockchain network, a contract file corresponding to the contract deployment request is acquired. The contract file is generated by performing content extension on a smart contract corresponding to the contract deployment request. Validation is performed on the contract file based on an analysis result of the contract file and a blockchain account book, wherein the validation is used to characterize performing validation on a secret key of the contract file, a content of the contract file, and a signature of a contract participant. The blockchain account book is generated by pre-executing a contract deployment transaction. In response to the contract file passing the validation, a smart contract corresponding to the contract deployment request according to the contract file is determined.

Blockchain-based data processing method and apparatus

Embodiments of the present disclosure provide a logistics information processing method and apparatus, and a device. The method includes: a blockchain node receives a locking request sent by a handheld terminal, and the locking request includes an identifier of an electronic lock on a logistics box and a waybill number of an item in the logistics box; the blockchain node acquires an unlocking key of the electronic lock corresponding to the waybill number according to the locking request, and the unlocking key is confirmed by a receiving terminal corresponding to the item; the blockchain node generates a locking instruction according to the unlocking key and the waybill number, and sends the locking instruction to the electronic lock, where the locking instruction is used to instruct the electronic lock to lock, and store the unlocking key and the waybill number. Logistics security of the item is improved.
