Description
Technical Field
The present invention relates to the field of block chain technology, and in particular, to a method and system for band type data processing based on a block chain.
Background
The blockchain is a brand new distributed infrastructure and computing mode that uses blockchain data structures to verify and store data, uses distributed node consensus algorithms to generate and update data, uses cryptographic methods to secure data transmission and access, and uses intelligent contracts composed of automated script codes to program and manipulate data.
In the normal block generation, taking 128 seconds as an example of generating a block in a preset time, a node generates a block until the 128 th second, and the block is sent after the block generation is completed, but the node may already receive the previous block and complete the processing in the 10 th second, so that the node is empty and wastes 118 seconds, and in addition, the number of people who send the 129 th second sending transaction after the 128 th second sending transaction is completed is 127 seconds more and can obtain the processing, and the performance and the experience are reduced.
Therefore, how to solve the problem of transaction processing stagnation and improve the user experience performance becomes a great research direction in the field of block chains.

Detailed Description
The invention is described in further detail below with reference to the figures and specific examples. It should be noted that the technical features involved in the embodiments of the present invention described below may be combined with each other as long as they do not conflict with each other.
As shown in fig. 1, a block chain-based band-type data processing method is applied to any node on a block chain network, and the band-type data processing method includes:
firstly, a user updates local account information; presetting block generation time 256s, wherein the first 128 seconds are advanced preprocessing time, and the last 128 seconds are transaction advanced processing time;
secondly, within the advanced preprocessing time of 128s, the node receives the previous block, stores the previous block in the local disk, and immediately checks the validity of the information contained in the previous block and processes the information.
Within the 128s transaction advance processing time, the node receives and verifies that a new transaction is processed.
Preferably, within 128s, the node cannot process all transactions contained in the previous block, so that the node processes the transactions for more than 128s of the whole block, thereby missing the block-out time of the node, causing the block to be discarded after the block signature is sent out and being considered invalid, thereby causing the transaction processing in the current time period to be invalid, and losing the performance of the 128s, at this time, the transaction processing opportunity needs to be adjusted, the next block is processed immediately after the previous block is received, regardless of whether the time of the next block is up, and the block can be immediately output only when the time is up during the processing, at this time, because the block is the time up to immediately output block, for the next block, it can process the transactions for 2 128s, namely 256s, as long as the block can be generated within 256s, it does not waste a little time for the node to process the transactions, and no interruption exists in the midway, so that the time utilization efficiency is greatly improved.
Then, processing the current unprocessed transaction; collecting the processed transaction information in a new block; after the processing of the unprocessed transaction is completed, if the preset time 256s is not used up, the new transaction is waited for.
When a new transaction is received, the new transaction is verified and processed, and the processed transaction is collected in a new block; circularly waiting and processing a new transaction according to the same operation steps;
and finally, when the preset time 256s is consumed, signing the block, and sending the block to the block chain network.
As shown in fig. 2 and fig. 3, a band data processing system using blockchain includes:
a user terminal module: the user terminal module comprises an account updating unit and a block generating unit, and when block generating time is preset, local account information is updated, and a new currently empty block is created;
a data processing module: the data processing module comprises a receiving unit, a data reading unit, a checking unit and a processing subunit, and is used for processing the new transaction received at the user terminal module and the overtime unfinished transaction of the previous block according to the sequence;
And the signature sending module comprises a node signature unit and a block sending unit, and when the preset time consumption is completed, the signature sending module collects the transaction processed by the data processing module into the new block, signs the transaction and sends the block to a block chain network.
An operation process for applying a blockchain-based band data processing system specifically includes:
firstly, a user logs in a terminal server, a data processing system automatically updates account information corresponding to a user account, and a terminal operation mode is started;
secondly, when the node receiving unit receives the previous block, the data reading unit stores the previous block into the local disk, the checking unit immediately checks the legality of the information contained in the previous block, and the processing subunit processes the information.
Then, if the preset block generation time 256s is not used up after the unprocessed transaction is processed, waiting for the arrival of a new transaction;
when the node receives the new transaction, the new transaction is checked and processed, the processed transaction is gathered to a new block, and the new transaction is circularly waited to be processed according to the same operation steps.
Finally, when the preset time 256s is consumed, the node signing unit performs block signing on the transaction processed and completed within the preset time 256s, and sends a new block comprising node information, transaction information and data signing information to the blockchain network.
According to the band type data processing method and system based on the block chain, under the condition that the current block generation rule is not changed, the blank block is created in advance, the timing of block transaction processing is adjusted, information contained in a new transaction and a previous block is collected, the problem of transaction processing stagnation is solved according to a sequential processing mode, and the user experience performance is improved.
The above-mentioned embodiments are only preferred embodiments of the present invention, and do not limit the technical scope of the present invention, so that the changes and modifications made by the claims and the specification of the present invention should fall within the scope of the present invention.
