example

[0128] In the establishment of the blockchain for financial field activities, there are two existing examples of banks and securities financial institutions. The types of bank transactions include deposit business, loan business, loan business, securities investment business, bank card business, guarantee business, and electronic banking. The types of securities transactions include stock transactions, bond transactions, fund transactions, and transactions of other financial derivatives. Bank A is the head office, bank B and bank C are branches, securities A is the head office, securities B and securities C are branch offices. When building a complex chain structure blockchain, the types of transactions to be carried out by banks and securities are counted and numbered, and two transaction type index tables are established. According to the identity, behavior, transaction capital source, amount, frequency, flow, nature, etc. of bank and securities customers, it complies with t...

Abstract

The invention discloses a financial big data-oriented multi-way tree structure block chain integrated optimization storage method. The method comprises the following steps of 1, constructing a multi-way tree structure block chain integrated optimization model; 2, constructing a private chain block based on a Merkle tree; 3, constructing an alliance chain block based on a Merkle Pattercia tree; and4, establishing a communication consensus mechanism of the block chain. By means of the method, the multi-way tree structure block chain integrated optimization storage method oriented to financial big data is provided, and compared with an existing storage method, the storage efficiency, expenditure and other aspects are obviously improved; and during query, the query efficiency and accuracy arealso remarkably improved, and the application requirements in the current big data era are met.

Description

technical field [0001] The invention belongs to the field of block chain data storage, in particular to the design of a block chain storage system, in particular to the design of a multi-fork tree structure block chain integrated optimization storage system oriented to financial big data. Background technique [0002] Blockchain is a new computing paradigm and collaboration model that can establish trust at low cost in an untrusted competitive environment. Due to its characteristics of high storage density, tamper-proof, and traceability, applications based on blockchain technology are becoming more and more widely. The blockchain stores data by adding blocks, and the data is stored on a single chain, but with the expansion of time and transaction data, it is easy to cause data expansion, which may lead to a decrease in storage and query efficiency. At the same time, the single-chain storage mode cannot realize associative storage or regular storage in complex or classified...
