SpaceChain AMA Telegram — June 15, 2018

On June 15, the community came together to ask SpaceChain co-founder Zheng Zuo questions. We have compiled the AMA here from our SpaceChain English Community Telegram Group ( Thank you for your participation.

1. Is there any partnership in progress with big company like airbus
We are speaking to a couple of companies from U.S., UK, Israel, Singapore, New Zeeland etc. Have signed MOUs with some of them. We will be announcing it when all things are confirmed. It is exciting to see many space companies begin to get in touch with blockchain.

2. Why don’t you counter the arguement of scam(cctv) actively? many investor think that silence is the same as admiting a fault.
We have contacted the channel, and they have accepted our complaints regarding the flase statement. We have also actively contacted the police station that was mentioned on the news. They have not gotten back to us yet. There is no government officials contacted us ever. It was a falsed claim. We would rather focus on building the tech and product. However, we hear you and we will begin to be more active in the community.

3. How many engineers and marketer are in your team?
There are 20+ people working in the projects. And another 20+ engineers are contributing codes for spacechain OS.

4. Do you and advisior still have spc? no selling?
The team and Advisors have NEVER sold any SPC on exchanges. NEVER.

5. Is there any plan to join new powerful advisor?
Yes, we have just signed one of the top Economists in the industry. More information will be announed soon.

6. I heard that SpaceChain has a plan of mainnet in the future. Is that really possible? or just plan?
We are focusing on the building the SpaceChain OS that are compatible to many different public chains. We integrated with Qtum, and now working on ETH. We do not have plan to launch our mainnet at this moment, but we do want to integrate more public chains so we can have more interactions with more open source communities. However, this is a fast growing industry, we will be watching how the goes and decide what is the best route for the development of the project.

7. What is the Jeff Garzik and Tim Draper’s role for SpaceChain?
Jeff is my Co-founder and CTO. He designed our technical architecture and have been making a lot of connections and infuence for SpaceChain in both of blockchain and space industry.

Tim is our advisor and investor. We have frequent communication on things. He also did some very helpful intros in the industry. He has been very supportive and friendly to us.

8. How much duration the satellite is able to be accessed for transferring the data in the whole day? I am worried the time is too short so too hard to communicate something.
Great question. It depends on the capacity of the satellites. Most of the cubesats have limited bandwidth and it takes longer time to do upload/download. The pros of launching small satellites are: they are cheap and we can build it fast. We will have opportunities to test it out before we spend on a lot of money on building big ones.

9. Is there any plan to hold regular AMA in a month? we want to see you every month here.
I will begin to pop up in the community more often. Thanks for the support.

10. I know SpaceChain is working with China space company. Is there any partnership with China government?
We are working mainly with Commercial space companies. We are working with space companies in Singapore, U.S., Isreal, U.K. and New Zealand companies.

11. Please share with us an up to date roadmap
Great to see you here. We have uploaded the SPC OS two months ago. Now 80% of the documentation is completed. And we have received many interests to develop on our OS. If there is community member wants to test our IDE, you can go to our website ( to apply for it.

12. How are you attracting the developers to work on the SpaceChain OS platform?
We are talking to many space companies that are using traditional OS. For enterprise user, we have built partnership with 6 companies to develop applications or space craft. They all will use IDE for SpaceChain OS to make the development. Until now we have helped 3 companies to install IDE, and they have already used it in their companies. We will continue to promote it with enterprise partners.

We have also integrated Qtum on SpaceChain OS. The Qtum developers community has good awareness about us and we have received about 35 applications to test the IDE. We are also integrating ETH on SpaceChain OS, we believe once we complete that, we can also get more developers working on the platform.

We are about to start a student ambassador program that will help us gain more influence on campuses.

13. Do you know Skylon, a UK company? I heard rumors of a possible partnership.
I do not know them. Would love to get an intro.

14. Will we have masternodes?
No, no masternodes.Today, Qtum P2P nodes. Future, SpaceChain blockchain P2P nodes.

15. Any powetful marketing plan? People are getting and getting less attention about SpaceChain now.
Our new CMO, Eric, has made a very detailed marketing & community strategy for the next 2–3 years. This is AMA is a kickoff for the plan.

16. Is SpaceChain working on ETH as well?
Yes, while we stay close with the Qtum community. We are integrating ETH on SpaceChain OS. Details:

Details: SpaceChain OS development

The Ethereum homestead porting work started on the SpaceChain OS.

Ethereum Homestead is a user software developed by the Ethereum Foundation and Ethereum Research Organization that enables users to complete the creation of nodes on the local computer and perform decentralized applications on Ethereum.

The migration of Ethereum homestead consist three phases: Assessment, transplantation and testing. The software team determines the migration requirements during the assessment phase, understands and splits the homestead module architecture, grooms the homestead’s external library dependencies and determines the specific migration plan. During the migration phase, the team migrated the homestead’s modules and required external dependencies to the plan. After that, the software team will design the homestead test plan according to the requirements and test whether its function and performance meet the expected requirements.

Currently, there are many versions of Ethereum homesteads, of which the more mainstream versions are Geth (implemented by Go), Parity (implemented by Rust) and CPP-ethereum (implemented by C++). The software team was the first to port the current CPP-ethereum homestead. The software team has completed the confirmation and split of the function of the CPP-ethereum homestead’s own module last week and determined the external libraries and dependencies required by the homestead.

This week, the team started the migration of external libraries. This includes the C++ base library and the interface-dependent libraries for homestead-side service calls (including database interface libraries for data storage, network support libraries, etc.). The software team will need to analyze the functionality and underlying interfaces of these external libraries and convert them into the project’s own Makefile (the file that specifies the project compilation rules) in a dependency relationship. Some of the underlying interfaces required by external libraries are different from those supported by SpaceChain OS and need to be re-implemented before adding them to the Makefile.

At present, the basic library migration has been completed and the team is working on the implementation of some of the underlying interfaces of the homestead service support library. After completion, the overall compilation of the Ethereum migration project will begin, and the errors in the missing interfaces and compilation rule settings will be found based on the problems that have arisen.

The evaluation of other versions of homesteads is also in progress and we are in the process of updating the open source library.

This week, the team is issuing the following documents:

SPC00205 Introduction of SpaceChain OS EN V1.00

This document is the English version of the previously published SP002005 SpaceChain OS Profile CN V1.00. The team is actively carrying out translation work so that it can be more widely shared.

17: It means ETH version SPC will be launched like medibloc? I want to know if a set of cubes has a lifetime of 5 years and is not too inefficient.
Thanks for translating! Like I answered the question above, launching cubesats are great way to test the concept and technology.
