Description

Transaction record management method, system and storage medium based on block chain technology
Technical Field
The invention relates to the technical field of computer networks, in particular to a transaction record management method based on a block chain technology, a transaction record management system based on the block chain technology and a computer-readable storage medium.
Background
The Blockchain (Blockchain) is a distributed database system participated by nodes, and has the characteristics of being unchangeable and unforgeable, and can also be understood as an account book system (leader). It is an important concept of bitcoin, a copy of the complete bitcoin block chain, which records every transaction of its token (token). From this information, the value that each address has at any point in the history can be found.
A block chain is composed of a string of data blocks generated by cryptography, each block containing the hash value (hash) of the previous block, and is linked to the current block starting from a starting block (genesis block) to form the block chain. Each chunk is guaranteed to be generated after the previous chunk in time order, otherwise the hash value of the previous chunk is unknown. These characteristics make bitcoin double-blooming (double-blooming) very difficult. The block chain is a core innovation of virtual currency such as bitcoin.
One of the biggest difficulties in the technical implementation of mobile wallets is the extraction and presentation of transaction records. The block chain network transaction is greatly different from the traditional transaction, and the traditional transaction is that the current transaction takes effect immediately without intermediate node confirmation as long as the transfer is realized by two parties participating in the transaction. Once a transaction of the blockchain occurs, the transaction must be confirmed by miners on the blockchain first, and the transaction is only effective currently, and a period of time is required from the beginning of the transaction to the completion of the transaction, and the length of the period of time also has a great influence on the user experience. According to the conventional blockchain technology, each node stores all transaction records of the whole blockchain network, a huge storage space must be prepared locally, and 1T may not be enough at present. Such a backup transaction record would be substantially impossible with a mobile wallet and it is determined that the transaction record presentation for a mobile wallet would be less likely than on a stationary computer device such as a PC.
Currently, it is very inconvenient for how the transaction record information on the mobile wallet is displayed before and after the transaction is submitted to the blockchain agent node. The main proposed solutions are the following two:
the first scheme is as follows: after the transfer transaction occurs and before the miners node does not confirm the transaction, the current transaction cannot enter a specific block of the block chain, and the current transaction is not displayed on the mobile wallet until the current transaction is confirmed by the miners. The user experience is very poor, the user feels no security feeling, and the account transfer transaction display cannot be displayed in time.
And after the transfer transaction occurs, the mobile wallet reads the transaction information in the current block from the block chain network every time a block is generated from the initial block, displays the current transaction information in the transaction record list, and stores the transaction record to the mobile equipment, so that the storage space of the mobile equipment is greatly occupied, and the frequent block synchronization with the block network is carried out, so that the network flow is greatly increased, and the adverse effect is generated on the user. And when the transfer transaction occurs and no miner node confirms the transaction, the mobile wallet detects whether a new block is generated or not continuously during the period, whether the current transfer transaction is in the block or not, and only the current transaction can be cached locally at the mobile wallet terminal, so that the confirmed transaction is automatically changed after the time of the miner transaction is up.
Therefore, there is a need to provide a new transaction record management method based on blockchain technology to solve the above-mentioned problems in the prior art.
