Embodiment Construction

[0020] 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.

[0021] like figure 1 As shown, the data organization and storage method based on Java smart contract of the present invention comprises the following steps:

[0022] S1: Decouple the nested collection or mapping data into a column cluster table. In the column cluster table, each column is each meta field of the object, and the columns with association or similar relationship are integrated into a column cluster. The data in each row corresponds to an entire object, and each cell in each row is the attribute value of each meta field of the entire object;

[0023] S2: Erase the type information of the objec...

Abstract

The invention discloses a data organization and storage method based on a Java smart contract. According to the method, a data organization and storage method is realized on the basis of a new data organization structure column cluster table, and a complex mapping and set nested structure is converted into the column cluster table, so that the problem of too slow serialization and deserializationis avoided, the contract execution speed is increased, the atomicity of data access is enhanced, and visualization is facilitated.

Description

technical field [0001] The invention relates to the storage field of blockchain data, in particular to a data organization and storage method based on Java smart contracts. Background technique [0002] Blockchain is a new type of decentralized distributed storage technology, which can safely store digital currency transactions or other information data that needs to be stored, and can ensure that information cannot be forged and tampered. Transactions on the blockchain The confirmation is completed by all nodes on the blockchain, and its consistency is guaranteed by the consensus algorithm. A public ledger is maintained on the blockchain, and the public ledger is visible to any node on the storage block. [0003] The term smart contract was proposed by Nick Szabo, an interdisciplinary legal scholar. His definition of a smart contract is "a smart contract is a set of commitments defined in digital form, including agreements on which contract participants can execute these co...
