SpaceChain Weekly Report (Nov 5 to 11)
This week, we’ve launched our second-generation blockchain node into space, been listed on Bittrex and updated our technical progress report.
We have liftoff! Our second-generation blockchain node has been launched into space. The node is carrying SpaceChain OS — our open-source operating system that allows it to interface with the Qtum blockchain and network — making it the first fully functioning space-based Qtum blockchain node. Watch it orbit the earth in real time!
This operating system is available to anyone, anywhere in the world, allowing a global community to access and collaborate in space. Read more here.
Blockchain node in space
- Successful launch of our blockchain node in space
Our node successfully launched at 6:57am on 25 Oct 2018. After entering the scheduled track, the platform was put into a steady state and powered on. After confirming the state of the platform, the ground station personnel began to power up the load and test the load status last week.
When the node transited, the ground station sent a telemetry packet request to the node via the UHF/VHF signal. After receiving the request, the node packed and sent the current status information of the payload back to the ground station. The information of the package includes the important state parameters of the SpaceChain OS running on the payload, as well as the hardware state information of the payload itself. These parameters are used by the ground station to determine the operational status of the load after receiving the data.
The load status data is collected after the load is turned on, and is automatically stored in the non-volatile memory chip on the load board. Even if the load is unexpectedly powered off, it can be stored for several years, ensuring that the current state or load of the load can be acquired at any time. Status information before the error.
Currently, judging from the payload status information downloaded from the platform, the blockchain node in space is running normally. No abnormality was found in the overall communication link and load power-on operation. The team will perform a full functional test for the next period of time.
- Changes and improvements to the Ethereum node
Currently the ported version of the SpaceChain OS Ethereum client hasn’t shown any abnormalities yet. The team has imported the block data of the downloaded ropsten test chain and is currently testing the basic interface through the node environment.
Our team is also thinking about adding a light synchronization mode to the ported version in order to rectify the issue of encountering an excessive amount of synchronous data when the embedded nodes are used in spacecraft or low-power devices in the future. Currently, the engineers are verifying the feasibility and evaluating the workload.
- Open-source H3 board
On the All-H3 hardware platform, the Qtum software system based on Linux will be open source, in addition to the light node Qtum-electrum system under Linux. The transplant test of the full-node Qtum has been completed, and GitHub is being updated.
