# LightDisk
The Times 03/Jan/2009 Chancellor on brink of second bailout for banks.

#### Introduction
What you see is a blockchain-based storage system. This system can generate a pair of public and private keys among multiple nodes(devices) through asymmetric encryption for users. Users then can use the pair to encrypt and upload data and decode and download them .

#### Bug List
1.The inside and outside of the LAN interconnect with each other, which means NAT traversal isn't realized.
2.Live nodes are likely to be found dead in LAN.
3.The system so far has only supported the Coinbase.(General types of trade are being developed at present.)

#### Software Architecture
JDK 1.8+  
Spring Boot 2.0.1  
[Apache Gossip](https://gitee.com/TimVanX/incubator-retired-gossip)

#### Tutorial for Installation
1.Command line interface:  Configure JDK or JRE local environment variables (version 1.8+), unzip and run "open.bat".
2.Login interface:No war package now. You need to use Git to import this project into IntelliJ IDEA, run the com.timvanx.Application entry, start the Spring Boot project, with the default entry address http://localhost:8080/.

#### Instructions
##### Command Line Interface
1.If no seed node exists, we can input '1' and set ourselves as the seed node. 
2.If a seed node already exists, we can input'2'at first, and next the seed node's IP address and port number.

2.Structure Chart(The blockchain's structure is similar to the bitcoin's data structure in that files serve as sources of node data of each merkle tree's leaves. )
