Embodiment 1

[0047] see figure 1 , the present invention is a high-value data uplink system based on a blockchain oracle, including a node statistics module, a screening and sorting module, a memory allocation module, an uplink analysis module, and an uplink update module;

[0048] In this embodiment, according to the unstored memory and stored memory of several sub-nodes on the blockchain, the memory availability rate of several sub-nodes is obtained and several sub-nodes are screened to obtain nodes to be linked, so that the stored memory usage More sub-nodes do not upload high-value data to the chain; classify several nodes to be chained according to the storage average value of the unstored memory, so that different sizes of unstored memory can store different high-value data; according to The memory division ratio divides the unstored memory, so that high-value data and other data can be stored separately in the unstored memory without affecting each other; different data in the infor...

Embodiment 2

[0079] see figure 2 , a high-value data on-chain method based on blockchain oracles, including:

[0080] Obtain the storage information on the block chain, the storage information includes the first storage data and the second storage data, the first storage data includes the unstored memory of several sub-nodes; the second storage data includes the stored memory of several sub-nodes, the The storage information is sent to the central node.

[0081] According to the unstored memory and the stored memory, the memory availability rate of several child nodes is obtained, and the child nodes corresponding to the memory availability rate not less than the preset standard availability rate are marked as nodes to be linked; The memory availability is sorted in descending order to obtain the sorted set of the first node.

[0082] According to the first storage data in the storage information, the storage mean value of the unstored memory is obtained, and the difference between the ...

Abstract

The invention discloses a high-value data uplink system based on a block chain oracle machine, which belongs to the technical field of block chains and comprises a node statistics module, a screening and sorting module, a memory allocation module, an uplink analysis module and an uplink updating module. The method comprises steps of acquiring storage information on the block chain, acquiring memory availability rates of a plurality of child nodes according to unstored memory and stored memory in the storage information, and acquiring to-be-linked nodes and a first node sorting set according to the memory availability rates; obtaining a storage mean value according to first storage data in the storage information, and obtaining a second node sorting set and a division sorting set through the storage mean value; the invention further discloses a high-value data uplink method based on the block chain oracle machine. The method and the device are used for solving the technical problem that high-value data cannot be reasonably linked according to memory use conditions of a plurality of child nodes in an existing scheme.

Description

technical field [0001] The invention relates to the technical field of block chains, in particular to a high-value data chaining system and method based on block chain oracles. Background technique [0002] The oracle machine is like a third-party data agent in the blockchain world. When a smart contract on the blockchain has data interaction requirements, the main thing the oracle machine does is to process the requests provided by the smart contract in the blockchain. , to transfer some information and data outside the chain to the chain. [0003] When the existing blockchain data is uploaded to the chain, there is no reasonable screening and classification based on the memory usage of several sub-nodes on the blockchain, so that high-value data with different storage cannot be stored on the chain reasonably, resulting in high-value The effect of data on-chain is not good. Contents of the invention [0004] The purpose of the present invention is to provide a high-valu...
