Problems solved by technology

In the existing scheme, when the chain is abnormal, it is generally processed immediately, and the data is re-uplinked immediately. Such behavior is likely to cause excessive data retry when the blockchain cannot provide services for a short time. If the service is down during the logical process, it needs to be considered after restarting to process half of the data in the previous uplink process, resulting in more complicated processing logic

Embodiment Construction

[0017] The present invention will be described in detail below with reference to the accompanying drawings and preferred embodiments, and the purpose and effect of the present invention will become clearer. It should be understood that the specific embodiments described here are only used to explain the present invention and are not intended to limit the present invention.

[0018] The information on the blockchain can ensure the credibility of the data itself due to its non-tamperable characteristics. After saving the data in the blockchain, it can prevent the record from being modified later and ensure the security of the storage. When using the blockchain to store data, it may fail to be uploaded to the chain due to network or other reasons. At this time, there needs to be a mechanism to re-uplink the failed records of the chain, so as to achieve a relatively stable network in the event of network fluctuations or other circumstances. High chain success rate.

Abstract

The invention discloses a data linking exception retry method based on a block chain. The method employs an independent scanning detection module, reduces the logic complexity and module responsibilities compared with a conventional mode of immediate retry when an exception occurs, and can prevent a part of data linking interruption and loss caused by service downtime in a conventional scheme. Through control via distributed locks, only one service in a plurality of levels of scanning detection services detects and scans records or data with data linking failure to determine whether to re-linkor not. The subsequent linking process is concurrently carried out through the linking service. so that repeated sending behaviors in a distributed lockless environment is avoided, and the overall efficiency and reliability of the linking process are improved.

Description

technical field [0001] The present invention relates to the field of blockchain-based data uplinking, in particular to a blockchain-based data uplinking exception retry method. Background technique [0002] Blockchain technology, blockchain refers to a technical solution for collectively maintaining a reliable database through decentralization and trustlessness. It is the underlying technology of digital currencies such as Bitcoin and Ethereum. In layman's terms, blockchain technology refers to a way for all people to participate in bookkeeping. The transaction confirmation on the blockchain is completed by the consensus of all nodes on the blockchain, and after the consensus is successful, it is packaged and written into the block. The blockchain maintains a public ledger for storing all transactions on the blockchain network. There is a database behind all the systems, and you can think of the database as a big ledger. Then who will keep this ledger becomes very importan...
