Embodiments of the present disclosure relate to methods, devices, a computer readable storage medium and a computer program product for processing or managing a blockchain transaction. In a method for processing a blockchain transaction, a blockchain node of a blockchain for processing the blockchain transaction receives a transaction request, the transaction request indicating at least a initiator of the transaction, transaction content and a transaction recipient of the transaction. The blockchain node computes, based on the transaction content, a transaction fee for processing the transaction. The blockchain node determines whether the initiator of the transaction is a sponsored user of the transaction recipient, and determines a payment account from which the transaction fee is deducted in response to determining that the initiator of the transaction is a sponsored user of the transaction recipient. The transaction processing and management schemes as provided in the present disclosure enable ordinary users use blockchain services conveniently.

Blockchain transaction processing

Embodiments of the present disclosure relate to a method, a device, a computer readable storage medium and a computer program product for transaction processing on a blockchain. In the method, the blockchain node for processing a transaction receives a transaction request including a plurality of fields, the plurality of fields including a transaction task field including a plurality of clauses and each clause of the plurality of clauses indicating one of a plurality of tasks of the transaction. The blockchain node processes the plurality of tasks and determines that the transaction is successfully processed only in response to successfully processing all the plurality of tasks. The transaction processing as provided in the present disclosure enables multiple tasks to be processed through a single transaction procedure on the blockchain in an efficient way.

Transaction processing

The present disclosure includes IoT devices, block chain platforms, and IoT systems for recording transportation data of an object and methods of using the same. In some examples, IoT devices are one time programmed with a private key in a manufacturing process of the IoT device. In some examples, IoT devices may include at least one sensor configured to detect external environment data of an object during transportation of the object; and a processor configured to receive the data from the sensor and generate a data packet based on the data using a private key, the data packet including a unique identification number of the IoT device, the data and a signature generated according to the unique identification number and the data.

IoT devices, block chain platforms and IoT systems for recording transportation data of objects and methods of using the same

A method is disclosed for implementing trust Internet of Things (IoT) services in an IoT device and a user device. The IoT device receives from the user device an authentication request comprising a hash value, first encrypted information and second encrypted information, where the IoT device determines whether the user device is successfully authenticated based on determining the user device public key and confirming that the user device public key exists in a list of access permitted user devices of the IoT device.
