太空链07.24-07.30工作总结

太空区块链节点

SPACE NODES

本周团队主要工作如下：

太空节点与平台通信链路测试完成

团队与搭载平台团队共同完成了节点整体通信链路的测试工作。目前通信链路中各节点数据收发、请求响应一切正常。后续准备开始与搭载平台的整体测试。

注：节点载荷与搭载平台之间的通信链路测试成功表示载荷与平台已经具备集成测试的条件。

太空节点应用软件开发基本完成

团队完成了太空区块链节点基本版业务软件开发工作，能够响应地面发出的交易签名、下发数据命令以及节点健康状态的基本遥测数据请求。整体运行稳定，未出现异常。接下来，团队将对其进行迭代，加入新的功能和更多的安全机制。

注：本次，SpaceChain基金会将利用太空节点在区块链安全传输中的应用。

开源软件系统

SPACECHAIN OS

本周团队主要工作如下：

虚拟机软件问题修复

本周，团队在调试中发现虚拟机在运行Qtum钱包软件请求退出时出行log文件异常，经过排查，确定为数据文件与虚拟机文件系统不匹配造成的。目前团队正在对问题进行修复。

注：SpaceChain OS在3月就完成了全部的开源工作，已经支持Qtum的应用。目前团队正在不断完善与改进，主要针对即将开展的太空节点的应用方向，正在持续改进和优化，致力于为社区提供最优质的代码和支持。

开源硬件系统

SPACECHAIN HARDWARE

目前，团队正在研发基于H3的可支持Space Chain OS的开源硬件系统。本周主要工作如下：

基于H3开发板的应用研发

H3开发板Qt界面编程工作仍在进行中，截至本周已完成界面逻辑设计，提交一个可以评估的初样。

显示屏点外设基本成型，目前已经可以做到10帧的刷屏速率，满足功能要求。

Qt接口的测试实验通过，下一步进行Qtum主要功能的测试和界面编程。

注：H3开发板的基本功能已经实现，正在准备相关开源事宜。同时，团队正在基于此开发板探索一些基本应用。

SPC Weekly Report (July 23 – 29, 2018)

Our team has several tech and community updates. Check it out.

TECHNOLOGY PROGRESS:

Space Nodes

Finished testing of the overall communication link between space nodes and OS platform

Currently, each node in the communication link can receive data and respond to requests. Soon, we will start integration testing of both the node and the OS platform.

Note: The successful test of the communication link between the node load and the platform indicates that the load and the platform already meet the conditions for an integration test.

Finished development on the basic version of the space node software

Now, the node is able to respond to transaction signatures, data commands, and basic telemetry data requests for node health status issued by the ground station.

The overall operation was successful with no abnormalities occurring. Following this, our team will continue iterating by adding new features and more security mechanisms.

Note: This time, we will utilize space nodes in the secure transmission of blockchains.

Open Source Software System SpaceChain OS

Virtual Machine Software Fix

This week, our team found that during debugging, a log file appeared abnormal when the virtual machine requested to exit the Qtum wallet software. After investigating further, we determined that the reason for this abnormality was due to a mismatch between the data file and virtual machine file system. Our team is currently working on a fix for this issue.

SpaceChain Hardware

Currently, our team is developing the H3-based open source system that supports SpaceChain OS. This will be mainly what we're working on this week:

Research and development of the H3 development board-based application

Currently working on the programming of the H3 development board Qt interface. Up until this week, the logical interface design has been finalized, and an initial sample has been submitted.

The peripheral of the display point is formed with the 10 frame screen refreshing rate, which satisfies the functional requirements.

Testing of the Qt interface port has been completed successfully. The next step will be working on the interface programming and testing of Qtum main functions.
