Abstract

The embodiment of the invention provides a method for processing a service charge service through a block chain, a smart contract is deployed in the block chain, the method is executed by any node in a block chain network, the method comprises the following steps: obtaining a first transaction calling the smart contract, wherein the first transaction is submitted by a buyer client and comprises a buyer identifier, a commodity payment and a first commodity type as input parameters; and executing the smart contract based on the first transaction, thereby querying a first rate according to the first commodity type, calculating a service charge based on the first rate and the payment of the commodity, and deducting assets equal to the payment of the commodity and the service charge from an account corresponding to the buyer identifier in a block chain.

Description

technical field [0001] One or more embodiments of this specification relate to the field of computer technology, and in particular to a method and device for processing fee business through blockchain. Background technique [0002] At present, while the blockchain is receiving a lot of attention and application, smart contracts based on blockchain technology are also receiving widespread attention because of their advantages of high efficiency, transparency, and decentralized execution. For example, Ethereum provides an open source blockchain underlying system, which allows developers to develop various blockchain applications and write smart contracts by providing many interfaces. [0003] However, the scope of application of existing smart contracts is limited to the virtual world, and cannot cover real contracts in real scenarios in the real world, nor can it solve the problem of charging fees in real environments. For example, in the field of e-commerce, e-commerce plat...
