Job processing method, device and system based on block chain

Abstract

The invention discloses a job processing method, device and system based on a block chain, and the method comprises the steps: receiving job information from a block chain SDK, the job information comprising job content and job failure block height; obtaining the current block height of the block chain node; and in response to the fact that the job failure block height is greater than the currentblock height, executing an operation corresponding to the job content, and returning an operation result to the SDK. According to the invention, the consistent consensus of transaction results betweenthe blockchain nodes and between the blockchain nodes and the blockchain SDK can be ensured, so that it can be ensured that an external application end can define the transaction results in a quasi-real-time manner.

Description

technical field [0001] The present invention relates to the field of block chain network, in particular to a block chain-based job processing method, device and system. Background technique [0002] In recent years, blockchain has been mainly used in the fields of people's livelihood, urban services, cross-border payment, judicial rights protection and supply chain finance, traceability of public welfare donations, traceability of commodities, circulation of bills and invoices, cross-border payment, deposit certificates, and asset certificates. Business applications such as blockchain use blockchain as the underlying technology. In order to reduce the difficulty of applying blockchain technology for business implementation, blockchain developers will package SDK (Software Development Kit, software development kit) processing based on common functions at the bottom of blockchain, and external applications will integrate blocks in business codes. Chain SDK, the SDK exposes co...

Problems solved by technology

However, in actual production, since the time synchronization between blockchain nodes and between blockchain nodes and blockchain SDK cannot be guaranteed at all times, the following two situations may occur when setting the transaction tolerance timeout time: 1. On the blockchain node side, "current time = transaction start time + transaction Tolerance timeout time", the transaction is deemed to have timed out, and the transaction is directly considered to have failed, which has caused the blockchain SDK and blockchain nodes to fail to reach a consensus on the transaction result; the second is that some blockchain nodes "current time = transaction start time + transaction tolerance timeout" considers the transaction timeout, discards the transaction, and fails the transaction, resulting in block Unable to reach consensus among blockchain nodes
