Page 2 SpaceChain White Paper V 1.0 ABSTRACT SpaceChain aims to pioneer solutions for humanity to thrive in the coming space age. Combining blockchain technology with current astronautical resources and capabilities, SpaceChain will inspire more people to join the space community and advance the propers of space technologies together� SpaceChain positions itself as a private space agency with an open network driven by collaboration and transparency, using blockchain based technologies. Activating the principles of decentralization and international collaboration in an already vibrant global community, SpaceChain will leverage the dynamics of tokens and private funding to accelerate space development. SpaceChain was founded in March 2017 and has completed the development of SpaceChain Operating System (SpaceChain OS). SpaceChain OS has been successfully adapted to the Sparc V8 satellite operating system and achieved stable operations at the system level. The SpaceChain OS integrates Qtum blockchain technology and has established a platform for the development of space based applications. SpaceChain will be releasing fully functional satellites using the SpaceChain OS blockchain nodes in 2018. By harnessing the power of tokens, private funding and leadership, SpaceChain provides on an open source platform to accelerate outer space development and settlement. We will choose and execute missions that fit this blockchain-based philosophy.

Page 3 SpaceChain White Paper V 1.0 Part 1 Introduction The Value of Blockchain & Space Technology 1.1 The Trend of of Internet Technology Innovation: Blockchain The blockchain is a computer programming breakthrough Blockchain has received its share of news that solved the Byzantine Generals problem. Also known coverage in recent years and has captured as the Byzantine fault tolerance and an “error avalanche,” the interest of technologists and economists this concept was a generalized “unsolvable” proof that led since 2008. It solved the “avalanche of to roadblocks in software development. We have always errors” that the open Internet presented needed a third party that demanded a payment to perform where otherwise unrelated parties interact transactions or submit information to ensure that the over an untrusted network. For the first time, transactions were accurate and create a reliable history. information like digital signatures, digital Blockchain enables trusted exchange without middleman. contracts, digital keys to physical locks, digital It creates a secure and resilient shared history which is ownership of physical assets like real estate accessible anywhere in the world. The first real-world and digital money could take place in a matter application of blockchain is Bitcoin. Beyond cryptocurrency, of minutes between untrusted parties with no blockchain allows us to program transactions and signals need for a middle institution brokering history that allow for a decentralized, self-governing network with or ensuring honesty� And once the transaction no middleman and executable contracts between machines is complete, it is final. Blockchains represent called ‘smart contracts�’ the Internet-wide distributed ledger (or shared history) and server for both information and New technology can emerge in a manner that seems out- commerce that cannot be rolled back (also of-the-blue even though it is the culmination of decades known as immutable). Blockchain is the first of intense research and development by near-anonymous true community powered super computer. collaborators. Societies that encounter this technology when Now, blockchain can power smart contracts it is finally ready for users divide into two camps - idealists taking complex legal, commercial, and cultural citing it as proof of a revolution or establishmentarians who interactions programmed with no third party heap scorn on and attribute harm to the technology. A small intervention to execute between machines like subset of society trained in technology develops, discusses, computers, sensors, or systems like grids. and explores its capabilities. At this point, commercial interests that look for new ways to do business usually intervene and mainstream products are built on the findings. Profound changes then occur in commerce and culture� This evolutionary arc has characterised technologies from the printing press in 1440, personal computing in 1975, the Internet in 1993 and most recently, blockchain in 2008.

Page 4 SpaceChain White Paper V 1.0 1.2 Brief History of Telecommunication & Internet Evolution The future is already here, it is up to us to equally distribute it. A brief history of the Internet and discussion of the SpaceChain is advancing the evolution of evolution of blockchain reveals a true revolution the decentralized Internet to the next level by of our capabilities to understand, explore our essentially inventing true decentralized multi- world, and ultimately advance our species through tenant software capabilities and networked space technology. The combination of the Internet and on a satellite system. SpaceChain is building a the computer was a leap forward in our capacity universal OS that can be used across any satellite as a species. Combining worldwide broadcasting, to transform satellites into multi-use computers instant information dissemination, and platforms for rather than the single use satellites that are collaboration without geographic location has opened prevalent today. new avenues for advancing a more transparent and collaborative world where breakthroughs can benefit 1.3 Technical Platforms Have Led to the Era of all of humanity, all at once. Decentralized Space Tech The Internet, in the context of our global Currently the international space industry has two telecommunications evolution, represents the prevailing problems that hinder the development of most successful example of sustained, global, this industry as a whole: collaborative, decentralized development of • First, are security issues, which mainly information infrastructure. Blockchain, originated exists between countries; from Satoshi Nakamoto whitepaper, represents how • Second, conflicts of interest between the economic collaborative component is driving commercial corporates and Internet evolution. The decentralized Internet state-owned companies. today has become the widespread information and economic infrastructure and forms the true initial The first issue is being addressed by diplomacy prototype of what has been called the National and cooperation encouraged by leaders and Galactic Information Infrastructure. As JCR Licklider communities through collaboration and open of MIT wrote in a historic memo in 1962 discussing source technology� SpaceChain addresses the the concept of a “Galactic Network” of a globally second issue. Space technologies have always interconnected set of computers through which been closed source and highly guarded. The anyone at any location could access and change data problem is that in this type of environment, it is and programs, so did Satoshi Nakamoto envision a difficult for new businesses to utilize the existing purely “peer-to-peer version of electronic cash” that infrastructure, and access workable knowledge would “allow any one party” to send value to anyone outside of the organization, and for countries to else they chose without a third party intermediary on audit projects. Businesses have also avoided a series of computers running software called nodes. space technologies due to the high capital Tog Ethereum protocoler, with advances in computer requirement. Unlike other software arenas, it is programming on blockchain with programming not possible to build space-based applications and smart contracts like Qtum, we finally have the with low budgets. Lack of human capital, capability to fully transform entire industries. specialized professionals, and limited talent are also major constraints�

Page 5 SpaceChain White Paper V 1.0 Current space projects are dominated by governments, so they are hindered by external factors and become inefficient. Research and innovation are under-resourced. Purely commercialized space projects like SpaceX deserve more attention and are indeed seeing high valuations from very modest upfront investments. At the dawn of Internet age, startups benefited greatly from the traditional venture capital model. Typically, a business is owned by key members of the company and the shareholders keep working in the company and make contributions. Innovation and creativity of entrepreneurs in technology were able to thrive and succeed with the support of venture capital. However, for companies that require longer time and larger initial outlays for research and development (R&D) such as space exploration, VC model is not necessary the best option. Many technologies based on the VC model would be announced as unworkable when they need more time and capital investment to succeed and reach markets to thrive. For example, traditional satellite research and development cycles may drag across many decades. Once the funding for research is ready, it takes months to complete research and development before teams can apply for additional funding for next stages to get technologies to market. We have seen projects spend 5 years stuck in this cycle only to have their satellite prototype unable to launch. Tokenized fund raising provides flexibility and progressive ways to support such projects. With sufficient funding, the project can recruit the best talent, enhance internal efficiency and focus more on the long-term R&D. This is very important within space technology, where setbacks are to be expected and part of the cost of development. Hence, traditional VCs may not be willing to take the risk and leave this space to us to achieve somEthereum protocoling great under a crypto-economic model. Long-term feasibility and timeframes can be reached with smart contracts to lock and hold token sale funds with a clear roadmap and timeline for deliverables. SpaceChain is a private space agency that will partner other organizations where crowdsourced funding can be employed on collaborative projects and smart contracts employed to lock in funds till certain software markers are met to unlock them. SpaceChain’s decentralized application platform built on satellite technology will begin the opening of this industry and community. SpaceChain will promote SpaceChain OS to traditional space industry satellites, such as communication and navigation, among others. Also, SpaceChain will promote SpaceChain verification system to better aggregate and utilize current space resources in an open source, audited, and secure system. SpaceChain OS can be developed and used by different satellites and different organizations wherever they are located in the world.

Page 6 SpaceChain White Paper V 1.0 1.4 Introducing SpaceChain SpaceChain aims to establish a network infrastructure that is very much like the public telecommunication infrastructure we share globally. This network infrastructure will not involve any military or government bodies, and is only for use by the general public and by private individuals and organizations. People can access, build, and interact like they do on the Internet. SpaceChain’s first application is like a mobile app development platform. With blockchain software, we provide an application sandbox or app firewall so that independent apps may be uploaded to the satellite similar to apps on a mobile application layer. Until now, inter-satellite links (satellite to satellite communications) present a fundamental hurdle to a decentralized mesh network.In order to have this resilient mesh network, you first need satellite-to-satellite communication that is blockchain based. However, there are still security issues related to commercial satellites such as data integrity and safety of the satellite. SpaceChain invented SpaceChain OS which is a sandboxed blockchain technology that is built upon StylixOS and Qtum. This system will ensure the safety of data running on the satellite as the programs are operated at the immutable and completely public blockchain layer. The aim of SpaceChain OS is to enhance hardware capability while maintaining security. SpaceChain OS can adapt to global hardware systems and cater to varying satellite technologies. In order to ensure the safety features and functions of SpaceChain OS, the foundation will carefully evaluate each generation of SpaceChain OS through in-orbit testing, and it will provide the community with reliable open-source code and results. For more detailed SpaceChain OS information, please refer to “SpaceChain OS Whitepaper”. Internally, SpaceChain will tokenize and equalize technology and resources. This will optimize use of available technology and resources, and provide the space industry with an efficient and reliable consensus on value and collaboration to begin. SpaceChain was funded in March 2017 and has already provided solutions in the space frontier. SpaceChain OS development with infrastructure design and operating system started in November 2017. SpaceChain OS has been successfully adapted to Sparc V8 satellite operating system, and has achieved stable operation at the smallest system level. The migration from Qtum blockchain technology has achieved basic sandbox function, and the EVM Virtual Machine is on track to being developed in 2018.

Page 7 SpaceChain White Paper V 1.0 Part 2 path Realizing the Value of Blockchain Tech 2.1 General Overview of the Structure of SpaceChain 2.1.1 Upcoming Milestones: • 2018 March: complete all software development • 2018 April: complete operating system migration from the Zynq hardware system • 2018 September – October: complete running space verification of Zynq hardware • 2018 December: complete the R&D of first generation space chip based on RISC-V command • 2019 March: complete R&D of second generation hardware system and SpaceChain OS • 2019 May: complete in-orbit testing of second generation SpaceChain OS • Dates TBD: R&D of future generations of hardware system 2.1.2 Future Plans SpaceChain OS smart satellite system implementation and design of SpaceChain satellite hardware standards: • 2017 December: completed the design of first generation satellite platform based on CubeSat. • 2018 May: complete load design. • 2018 September: complete the production of satellites. • 2018 October and November: launch satellites. • 2018 November and December: complete testing of the satellite’s basic functions. • 2018 December: conduct software security test. • 2019: launch 100kg second generation satellite equipped with latest OS, and complete function testing; publish smart satellite hardware standards with partners. • 2020: launch one more second generation satellite, and achieve in-orbit upgrading of software without changing satellite platform; use better-performing hardware to design and build third generation satellite. • 2021 – 2022: launch 4 third generation satellites, and form a space network with previous satellites to support application development. • Further: move forward with the hardware and software upgrades while conducting in-orbit testing. SpaceChain’s goal is to integrate blockchain nodes on satellites to add a new dimension to the core framework of distributed ledgers. SpaceChain’s node satellites will bring blockchain to space and make use of existing space technology to build a worldwide distributed application layer. We are pioneering a new layer of infrastructure for the Internet of blockchains by taking advantage of space resources. SpaceChain’s platform features data collection, computing, applications, and storage. SpaceChain uses satellites as its operational nodes for realizing direct on-satellite data processing and secure in-space data storage through cryptographic technologies such as quantum communications. People everywhere will have access to this layer of infrastructure, just as they do the Internet wherever they travel with their various devices.

Page 8 SpaceChain White Paper V 1.0 SpaceChain will bring satellite technology beyond a repeater model (RM).Our partner will provide better language than traditional RM. RM essentially describes how most current satellites function. They usually take a signal from the ground and then simply broadcast live satellite tv or provide GPS or one other function at a time. RM allows very little actual data processing to take place on the satellite. SpaceChain’s system will change this model to a model that is multi-tenant with flexible software capabilities. Most satellites are single owner and thus single operator and single tenant. With SpaceChain, for the first time combining existing space technology and blockchain, we are able to create multi-tenant as a new user model and a new economic model for satellites. Additionally, SpaceChain has created a system to drive down the cost of space applications to allow teams and investors to do more development with their money. SpaceChain will combine and contract the cheapest rocket launches globally with multiple payoffs per rocket. As more cheap spacecraft reach orbit, we are able to have many redundant nodes in the network launched globally. Thus, our network also self-heals. We can see a mesh network in space of many satellites where loss and replacement will enable the network to be low cost and resilient in a “many plus cheap” model. These rockets will take off from many different sites and be ensured secure by open source, auditable practices that the larger respected technology and space communities can see and support� SpaceChain will employ this mEthereum protocolod to projects we undertake in space, including asteroids or planetary bodies exploration where we can send out many remote drones powered by apps run on satellites around celestial bodies in our planetary system. Hardware design also involves internal redundancies especially as spacecraft using our ‘smart’ satellites will have redundancy of computing.

Page 10 SpaceChain White Paper V 1.0 2.2 The Hardware of SpaceChain: Future of Internet Infrastructure What follows is a technical breakdown of SpaceChain from both the hardware and software perspectives. The key function of the blockchain payload is processing application safely on the satellite. To achieve this goal, the payload uses SpaceChain OS to provide the software environment to applications. Blockchain sandbox provides a safe environment and a high performance chip to guarantee all the software above. The main logic structure is shown below. Dapp … Qtum Wallet … Blockchain Apps Qtum -evm Qtum Software Libboost Libleveldb Libdb System library Libsnappy Libcrypto++ ��� POSIX Socket IO OS SylixOS Hardware Drivers Hardware Payload Hardware The beta vision payload hardware is on-board CPU and FPGA. The Payload provides a powerful processing module for Blockchain applications and OS. The module contains two main parts: • A very powerful ARM/FPGA on-board computer (OBC) designed as an efficient system for space application • The power system is divided into two, one for ARM and one for FPGA • Dual ARM Cortex A9 MPCore up to 800 MHz • 1GB DDR3 RAM/4 GB storage • Powerful FPGA module – 125K logic cells • Precision milled anodized aluminum heat sink to control thermal load and provide EMI shielding • Operational temperature: -40°C to +60°C • PCB material: 22 layer glass/polyimide • IPC-A-610 Class 3 assembly z7000

Page 11 SpaceChain White Paper V 1.0 In the future, blockchain payload will be rapidly upgraded to meet the future demand of blockchain applications. However, the existing processors have different problems that will slow the update rate down. For example, • x86 is complex and not open source, the internal structure of the processor is not clear, there may be a back door,unable to be safely controlled; • ARM has expensive intellectual property costs that will reduce user number; • SPARC is product of commercial companies; whole technical system has long-term sustained support risk; • MIPS and Power belongs to commercial companies which are focused on making profits, and their business model may not promote democratisation of technology. It is easy to have conflicts of interest with upstream and downstream companies; it may lack good industrial chain ecological support. To satisfy the update rate of blockchain payload, we need an open source processor project. In 2010, David Patterson, a distinguished professor at UC Berkeley, launched the RISC-V processor open source project, which has great properties like: • Free authorization, no patent barriers exist Block Diagram • Permanent non-profit foundation to dooperation management • Complete alliance of upstream and downstream industry • Two international workshop meetings each year At present, there are 50 core member companies, 270 companies and 29 universities participating in the RISC-V open source project. In the future, SpaceChain will develop a blockchain payload processor under the open source RISC-V ISA (Instruction-Set Architecture). The blockchain payload will be updated in performanceand reliability. Functional description The OBC is based on a Zynq-7000 All Programmable SoC (AP SoC) devices integrate the software programmability of an ARM-based processor with the hardware Microcontroller programmability of an FPGA, enabling key analytics and hardware acceleration while integrating CPU, DSP and mixed signal functionality on a single device. OS The OBC has a default SpaceChain OS installed. OBC has an I2C bus supporting bidirectional data transfer between masters and slaves, multi- master bus, arbitration between simultaneously transmitting masters I2C Interface without corruption of serial data on the bus. Serial clock synchronization allows devices with different bit rates to communicate via one serial bus and is used as a handshake mechanism to suspend and resume serial transfer� One of the main interfaces of the OBC to communicate with other subsystem hardware is a Controller Area Network (CAN) bus interface. It is a serial CAN Interface communications protocol that supports distributed real- time control with a high level of security.

Developers can create applications using the environment provided by SpaceChain OS. SpaceChain OS greatly lowers the difficulty of developing space applications while putting the resources like infrastructure to best use. Additionally, SpaceChain OS deployed sandbox technology ensures an interference-free environment for the applications.

Page 20 SpaceChain White Paper V 1.0 Partnerships with well-known universities through lab establishment, research, open courses, technical forums and other educational resources. SpaceChain Foundation will provide free resources for universities to take part in this exciting journey by providing free developer boards, hosting hackathons, and community development on SpaceChain OS globally. SpaceChain Foundation wishes to establish an eco-system where every contributor is fairly rewarded. Through such an economic model, more resources will be attracted into the space industry and more people will join the grand adventure of space exploration. SylixOS is an open source RTOS (Real-Time Operating System) project. SylixOS has been applied widely in various fields such as defense and security, aeronautics and astronautics, high speed railway system, smart grid, industrial automation, and motion control etc. In the SpaceChain project, SylixOS is used in the satellite platform to manage hardware resources and in the Blockchain payload to provide standard API interface and various system features for applications.

Page 21 SpaceChain White Paper V 1.0 Part 3 Tokenomics and Blockchain Structure of SpaceChain 3.1 SpaceChain Bottom Layer: Qtum The SpaceChain OS framework is divided into a Blockchain application layer that includes these layers: • Mainly Qtum provides the basic service API for smart contract and block chain application; • Qtum also offers a sandbox to guarantee the safety of applications processing; • Compatible for Ethereum protocol (ETH) ereum EVM to process Qtum smart contract; • Open for any public blockchain and their smart contract application; SpaceChain requires a blockchain technology with low power consumption, high stability, and strong expansibility. Qtum uses a PoS (proof-of-stake) consensus mechanism whereas most other blockchain technologies widely use PoW (proof- of-work) such as the Bitcoin blockchain and Ethereum protocol. PoW has high requirements for energy and hardware resources to work well so it is not suitable for satellite systems. Qtum has fully absorbed the accumulation of both the Bitcoin blockchain and the Ethereum protocol. Thus, Qtum technology has advantages in areas from code stability to third party support. In addition, Qtum uses UTXO technology to increase the network expansibility so that it can support a simple payment protocol SPV and the Lightning Network, and fully support the EVM smart contracts as well. So Qtum meets all the demands need to fully run blockchain technology on satellites. SpaceChain chose Quantum Chain Technology (Qtum) from the beginning after doing a complete technical assessment of both hardware and software necessary for space technology development. In addition to the above reasons, Qtum has many unique innovations. Qtum is the first smart contract platform based on UTXO and MPoS. It has pioneered the integration of the advantages of both BTC and ETH ecosystem. It has proposed and implemented the following core technology innovation: • Qtum uses efficient and secure MPoS consensus. As compared to Proof-of- Work(PoW) that is widely adopted by other blockchain technologies, MPoS consumes less energy and has no requirements of high-end hardwares. MPoS allows any coin holder to be able to mine the coin without wasting much electricity by staking them in the wallet. More importantly, MPoS can provide a more secure consensus and subsequently raising the cost of cyber attacking, by adjusting the height of block rewards and the allocation of transaction fees.

Page 22 SpaceChain White Paper V 1.0 • Qtum combines the strengths of both Bitcoin and Ethereum, making it more stable in terms of code structure. In addition, its adaptability towards third-party applications gives it extra edge over other blockchain technologies. • Qtum extends the UTXO technology of Bitcoin, and enhances the scalability of its network. It supports technologies such as Simple Payment Verification (SPV) and Lightning Network, as well as smart contracts that utilizes EVM virtual machines. Qtum designed and implemented Account Abstract Layer (AAL) technology, realizes conversion of UTXO model and EVM smart contract account model. Then developers can use EVM to develop smart contract without paying too much attention to the details of conversion of UTXO model. • Qtum invented Decentralized Governance Protocol (DGP). Through the smart contract embedded in the genesis block, DGP is able to govern the blockchain network and achieve autonomous distributed processing. This allows for faster updating of the network. The current changeable parameters that Qtum supports include: Block size,Gas limite,Gas dispatch and lowest Gas price. • Qtum is currently researching on high-performance virtual machine of new infrastructure. The innovative X86 virtual machine will tackle some problems existing in Ethereum EVM, for example, the lack of support for standard libraries and floating points, byte code of excessive size etc. Also, it will focus on building an efficient smart contract system built upon the UTXO model. Qtum is an open source project, see https://Qtum .org for more information� Qtum SpaceChain System library layer includes: • Open source software library support, including basic library libboost, libdb, libsnappy, libcyrpto+, etc. • Library provides services to the blockchain application layer through standard interfaces such as Posix and BSD sockets; • System library software is all open source project. • Operating system layer includes: • Standard interface support such as POSIX/BSD Socket/IO • SylixOS kernel • Hardware driver.

Page 23 SpaceChain White Paper V 1.0 3.2 SpaceChain Application Layer: Possibilities of Distributed Application (Dapp) The SpaceChain application layer presents many blockchain use cases. For example, a cloud computing app use case is backup nodes for data recovery for the most important encrypted data� The encryption and cryptography is performed on the satellite itself� In this case, the satellite is a first class actor where the satellite decrypts data payload. This makes the data extremely secure� In a “trusted execution environment,” we provide software code and data that we digitally sign here on earth and upload to the satellite. The satellite checks digital signatures before adding anything in the application sandbox before executing the program. This system provides authentication and blockchain capability. For developers and businesses this allows a “fail-fast” make-a-change-and-try-again approach or rapid iteration in contrast to the old world approach of launching a satellite per app. We are part of the NewSpace trend of commercialization of space. In the old world model there were only large governments deploying big satellites in space and big rockets costing billions of dollars to build, government-led and government-funded, with very little opportunity for private space companies to form to offer these services at a competitive cost. In the new model, led in part by China, we have a new space race where commercial companies from China, US, Russia, EU are competing to commercialize low earth orbit and driving the development of space technology. This is creating new markets and brings new funding into the space industry, creating possibilities for new economic models instead of one dominated by few owners and few operators. Decentralization keeps power distributed and access open for everyone. 3.3 How the SpaceChain Token Works on SpaceChain OS In the SpaceChain economic model, the token will connect to our SpaceChain OS and allow developers to upload apps onto the SpaceChain network and thus store data and execute programs on SpaceChain satellites. SpaceChain tokens must be bought in order to execute these SpaceChain apps much like a ticket to use a SpaceChain app for a duration of time or store one megabyte on a satellite. We are essentially building a market for space applications where a token will be a way for apps to be priced. For example, if one app is more popular than another then there will be more demand for that specific space application and thus more tokens used� This new economic model is what led us to evolve a space app model within a broad vision of developing an inner space application and communication network first. In the private space agency model where we wire the solar system for networking, after many years and many networks, we will see satellite constellations around the moon, as well as remote data centers around planets and other celestial bodies. These constellations will communicate with each other and form a backup. This will enable human and robotic settlement of space in the long-term� This mission to wire the solar system for networking will help realise a model called the Pony Network in Space. The Pony Network is an economic model in space for payloads and propellant technology systems whereby people and cargo travel to the moon and mars quickly and cheaply by taking a point-to-point transit approach over shorter distances. For example, a satellite being launched to the moon will not travel on a single a rocket going all the way to the moon, instead it will be launched to low earth orbit and transfer to another vehicle, using software on satellites along its path rather than having every single application running on its system. The entire network will be powered by and built on this token economic model.

Page 24 SpaceChain White Paper V 1.0 3.4 Community Evolution of Collaboration in Space Exploration Spacechain is based on a whole-of-mankind space exploration paradigm. The vision of Spacechain is to find a mechanism in the field of space exploration that can effectively mobilize the power of all mankind to meet this challenge in the face of great challenges. SpaceChain tries to solve the following three problems: 1.International space cooperation is relatively closed and there is an urgent need in the aeronautical field for a space cooperation alliance that is open and democratic. 2.The aerospace industry is currently closed to the public, and space exploration does not harness the strength of all fields. 3.The current space project has not found a balance between government and commercial enterprise� At present, international space cooperation is relatively closed. The reason is that security is the biggest barrier to cooperation among most countries. The other is the question of interests, which is the tension between commercial companies and state-owned companies. Therefore, establishing a cross-border, safe space security alliance that can protect the interests of participants in the field of aerospace will be the key to promoting deep cooperation in the field of space. To establish this alliance, a collaborative mechanism must be established with other companies and blockchains. The mission of SpaceChain is to break through the existing internal barriers of the world aerospace industry by establishing such collaborative mechanisms and give us full play to existing capabilities and enable optimal integration of available resources. SpaceChain aims to reach a consensus on security and common interests� For this purpose, SpaceChain developed SpaceChain OS, an operating system designed to create a true network in space. SpaceChain OS uses blockchain technology to encrypt the transmitted information to ensure the absolute security of information transmission, and the use of blockchain technology in the operating system and sandbox management so that each satellite can run safely. While achieving its security, SpaceChain OS hardware adaptability is enhanced to meet the different needs of different spacecraft. Efforts are being made to promote its compatibility with different spacecraft such as satellite systems, communications, navigation and remote sensing, satellite ground systems, space stations, spacecraft, space probes and other applications, in order to achieve a seamless network. In addition to international cooperation, the aerospace industry should not remain closed to the general public. Aerospace has always been a mysterious and opaque industry with a high barrier to entry because of its small market, high cost, and small number of qualified personnel. However, as we said before, the move towards space is a whole-of-mankind endeavour. It cannot be accomplished solely in the aerospace industry and requires widespread collaboration. There is a need to explore a model that will allow more people and more companies in other industries take part in human space exploration. Today, the 5G era in mobile data has brought about a thriving development in the satellite communications industry. The aerospace market has been growing. The mission of the SpaceChain Foundation is to solve the remaining two problems of high cost and limited qualified personnel so that more people can by part of a global endeavor to explore space�

Just as a mobile phone has changed power of a free society. This requires a more open and cooperative from a smartphone like Nokia to a smart commercial space socio-economic and technological development phone today, the shift is based on a strong model. Most current space projects cover both the government and and stable operating system. the commercial sectors.

The increase of the number of talents will greatly enhance the vitality of the industry and provide a continuous momentum of development for space exploration. SpaceChain Foundation has been supporting startups in the space industry around the world: • SpaceChain OSRZ Capital, an institutional investment firm. • Beijing Jiu Zhou Yun Jian, astartup specialized in liquid rocket engine, is collaborating with SpaceChain on an engine smart control system�

Page 27 SpaceChain White Paper V 1.0 Summary In short, SpaceChain aims to accomplish the following three goals: 1.break down barriers to cooperation and integrate the existing space resources so that space can better serve the earth and serve humankind, 2.lower the industry access threshold and costs, vigorously develop education and involve more people in space exploration, 3.establish a socio-economic model to support a sustainable commercial space decentralized, distributed program that will continuously grow knowledge and expand the cognitive boundaries of humanity. The SpaceChain Foundation hopes to take on the responsibility of pushing the boundaries of space and exploring the cosmos in which we live. SpaceChain hopes to attract more talent and resources, pool the power of all mankind, and join togEthereum protocoler in advancing space technology. We believe that the wisdom of bringing togEthereum protocoler a large number of talented people in a clear direction can lead to a unity of purpose in space exploration and the ultimate goal of a thriving human civilization.
