Over 600 experts and leaders from pilot smart cities departments attended the summit forum, gathering around to discuss how to foster the transformation of governance in the digital age with emerging technologies. \n\nAs a leading blockchain enterprise, an underlying operating system with ‘sovereign hierarchical management’ function has been largely accepted by governments and businesses, which was self-developed by ShenZhen GAChain Technology. Liu Yi, the deputy general manager of GAChain, was invited to give a speech on the theme of ‘Application of Blockchain in E-government’ by the organizer of this peak forum.\n\n![](https://cdn.steemitimages.com/DQmce7t2PCb1gNREGEoTjELkUPBbVck7UnxvuZQ3N697LyT/image.png)\n\nChinese governments are vigorously pushing the reform of service-oriented governance.Despite being mentioned dozens of times, the data sharing issue among departments is still a blocker in the way of building ‘digital government’.\n\nUp till now the governments have successively issued the “Interim Measures for the Administration of Government Information Resources Sharing”, the “Guidelines for the Construction of the “Internet + Government Services” Technical System” and the “Implementation Plan for the Integration and Sharing of Government Information Systems” , providing basic compliance for cross-department data sharing. At the same time,different places of city governments around China have also explored a series of useful practices.\n\nHowever, the promotion of cross-departmental data sharing did not reach a satisfying result -- a few data sharing platforms, poor shared platform system, sad submission data quality and low data utilization rate\n\nHow to effectively promote the cross-sector data sharing to build \"digital government\" still remains an urgent issue.\n\nIn January 2018, the “Administrative Approval Service Platform” for Guangzhou Nansha District has caught the attention of the superiors when the project approved. The platform is independently developed by Shenzhen GAChain Technology based on its innovative blockchain technology. After several months of business data testing, the platform has been optimized and realized solving a series of problems that existsd in the current e-government system.\n\nCompared with traditional platforms, “Nansha District Administrative Approval Service Platform” has the characteristics of intelligent and efficient automation, transparent and traceable business process, and information encryption.\n\nThe platform uniquely combines centralized management and decentralized business together and hands over management rights to the government, realizing automated supervision in the true sense. Besides, it adopts technologies like point-to-point transmission and encryption to reduce the manual costs and enhance the efficiency and data security.\n\nAt present, the Nansha District Administrative Approval Center has basically achieved the remarkable results of “zero running” in certain matters, where blockchain technology has played a significant role in opening up data silos and improving efficiency of business. The Administrative Approval Service Platform developed by GAChain has been rewarded as an excellent case in the annual “Smart City” section of the Information Association of China.\n\n![](https://cdn.steemitimages.com/DQmUf3gXSVpckuxyX2fvP5Dh7oS3E7eNd1JxSNe8p3wz46q/image.png)\nThe Administrative Approval Service Platform\n\nThe transmission and storage of government business data on the GAChain public chain is a remarkable attempt for governments utilizes blockchain technology.\n\nIn the past, governments worried about the security of data on public chain, and the technical bottleneck of the industry also limited the application promotion. For the first time, the GAChain has solved all the problems technically, and realized the seamless connection between the blockchain and the existing technology, which truly reflects the value of the blockchain.\n\nAccording to Liu Yi, GAChain will firmly follow the national policy of digital government and keep improving the blockchain technology to integrate the top-level design of the country with grassroots data collection. \n\n![刘总现场分享.JPG](https://cdn.steemitimages.com/DQmUM4jmwijofYcne6DFaQ1fiRLBqSaoiVben715LNp8sNC/%E5%88%98%E6%80%BB%E7%8E%B0%E5%9C%BA%E5%88%86%E4%BA%AB.JPG)\nLiu Yi,  the deputy general manager of GAChain\n\nThe policy news and industry trends from the peak forum indicated that the government is transforming towards a sharing, integrating, coordinating and service-oriented government, and has explored to promote more and more data information emerging technologies in developing e-government and solving data isolation problems. \n\n2018 is the first year of blockchain application, and it is also a year filled with ups and downs. After the heat of market cool down will people realize that only the enterprises that really dedicate in developing and promoting blockchain technology will last longer. GAChain keeps the spirit of pragmatic work deep in mind. How to effectively introduce the blockchain to the society is not only the concern of the government departments, but also the social responsibility and obligation of each enterprise.",

      "body": "As the spark of blockchain revolution is engulfing the world, the technology is becoming more sophisticated as the day goes by. Blockchain engineers the world over are putting thought into turning their product into an engineering marvel and such ideas give rise to buzzwords of the day. Getting a hold on these buzzwords becomes imperative for C-level execs as well as investors so that the knowledge remains perceptible and nothing becomes arcane.\n\nSo what is an ecosystem?\n\nEcosystem is originally a biological term used to describe a community of organisms interacting with each other and their environment. This analogy has extended to the blockchain world in which ecosystem refers to different actors involved and their interaction with one another, the blockchain DApp, and the outside real world.\n\nA typical blockchain may have multiple actors: users, organisations, miners, transactions, developers, engineers, investors, etc. Transactions happen to be the heart of the blockchain network. Without transactions, the blockchain network will become obsolete.\n\nOn-chain and off-chain transactions\n\nUnderstanding of the functional aspects of a blockchain ecosystem can be tricky, but a great place to start would be to learn about on/off-chain transactions.\n\nl Transactions which occur on-chain are the ones which are reflected on the public ledger (the blockchain) and these are visible to all the participants on the blockchain network.\n\nl On-chain transactions infuse trust, decentralization and transparency within the network.\n\nl Off-chain transactions are agreements between actors which are not reflected on the blockchain.\n\nl Off-chain transactions happen to be more cheap, fast, and private.\n\nLet’s dive in deeper to understand the working of blockchain ecosystems by taking up GAChain as a case study.\n\n![第一张图.jpg](https://cdn.steemitimages.com/DQmQCLt7LywKuKpde4pynezAuvvWkNNuusHBwpHCGhPJn6U/%E7%AC%AC%E4%B8%80%E5%BC%A0%E5%9B%BE.jpg)\n\nAll GAChain platform users are members of one or more ecosystems. The platform users access these ecosystems by using their private keys. In the GAChain ecosystem, any entity, person or asset is assigned unique digital identity credentials (public key number or hash code). Thanks to GAChain’s global ecosystem model, these credentials can be used to participate in global identity verification exchange.\n\nGAChain chose the ecosystem model for creation of applications because such a model enables implementation of several types of business, social, governmental and other activities autonomously.\n\nIn a blockchain ecosystem, autonomy is of utmost importance.\n\nThese ecosystems:\n\nEncompass actors which include a large number of applications and users (who create and/or use these applications).\nInclude a system to manage user roles and access rights for applications and users.\n\nAre self-sufficient systems which can operate on their own; if there is a need to connect and integrate with another ecosystem, that is also possible.\n\nCan be created by any GAChain users.\n\nThe creator of an ecosystem is known as an ecosystem founder.\n\nBy default, an ecosystem founder holds the complete set of rights for controlling the ecosystem: creating and editing applications, user roles, permissions, modifying ecosystem parameters, etc. However, control of these rights can be transferred to other members of the ecosystem. The procedure for accepting new members into an ecosystem is defined by its founder.\n\nTo ensure the autonomy of the ecosystem, the ecosystem founder, along with its members, creates a set of rules to control the operations within the ecosystem. In GAChain, these rules are known as smart laws. The smart law system establishes the rules for modification of access rights and other regulations.\n\nThe blockchain industry is growing at an exponential rate. The global blockchain technology market is expected to grow at a compound annual growth rate of about 51% from 2016 to 2022 and is set to exceed a market value of 2 billion USD by 2022.\n\n![第二张.png](https://cdn.steemitimages.com/DQmXVGtJVh3pPHqZsHbYikAVj8d5qy5svNPRS4TUkTv8ndc/%E7%AC%AC%E4%BA%8C%E5%BC%A0.png)\n\nThe statistics are quite overwhelming and exciting indicating the importance and potential of blockchain technology.\n\nSmart laws and consensus algorithms\n\nA necessary element of any organization of any activity are rules, norms, restrictions, by means of which the rights to perform certain actions are established. In an ecosystem, a set of norms and restrictions is formalized in the form of smart laws.\n\nThe totality of smart laws constitutes the legal system of the ecosystem.\n\nSmart laws, unlike smart contracts, are formed prior to the commencement of activities and are modified as necessary by the consensus of the members of the ecosystem. The rules for reaching consensus are prescribed in special smart laws.\n\nThe way consensus is achieved in a blockchain dictates how decisions are made by the actors and how anything gets done. Consensus always involves group-lead decision making. Hence, consensus protocol used in a blockchain network tells a lot about its degree of security, decentralisability and transparency.\n\n![最后一张图.jpg](https://cdn.steemitimages.com/DQmPGx9rnSTFoUMGPLxDjSDRSTwb2D8SiYxGj8GfzVuYwTr/%E6%9C%80%E5%90%8E%E4%B8%80%E5%BC%A0%E5%9B%BE.jpg)\n\nValidating nodes\n\nParticipants in the consensus protocol are known as validating nodes. These nodes run the current version of blockchain and have the right to validate transactions and append blocks to the blockchain. The more number of validating nodes in a network, the more secure the network is. Also, the more validating nodes are present in the network, the more time consuming the entire process becomes. Hence, the number of validating nodes has to be capped by employing a specialised parameter.\n\nThe right to sign a new block is transferred from one validating node to another subsequently within a defined period of time. In case a node is unable to create and sign a block in the designated time period, the right to sign the block is assigned to the subsequent node in the validating nodes list. This network structure provides for a maximization of the performance capacity necessary for operation of applications in digital ecosystems.\n\nConsensus protocol\n\nThere is a range of consensus protocol available for engineers to choose from. Even if no existing protocol suits the ecosystem, a new protocol can also be tailored from scratch. Some common protocols are Proof of Work (PoW), Proof of Stake (PoS), Proof of Authority (PoA), etc. Each of these functions differently with their own pros and cons.\n\nWith PoA, the main criterion for forming the list of validating nodes is NOT by taking into account the processing power (like PoW does), nor does it take into account the presence of a “share” (like PoS does). Rather, the authority of the node governs the consensus protocol.\n\nIn GAChain, to gain authority the applicant must be registered in the platform ecosystem by GAChain Consensus ASBL after completing the onboarding process and obtaining a majority of votes from the existing validating nodes. Voting takes place in the platform ecosystem, and if the outcome is positive, the data on the new validating node is sent by the transaction to the network where they are added to each parameter in the list of validating nodes.\n\nA final word\n\nThe ultimate aim in engineering an ecosystem model in blockchain is to enhance the factor of autonomy and performance. As the industry grows and the technology matures, new solutions will surface to cater to existing problems. A growing number of use cases can be thought of and implemented, keeping in mind the ecosystem model to solve real world issues like international remittances and legal compliance. This is just the beginning, a lot more is yet to come.",

The developer uses GAC to pay for development and resource usage,and there is no transaction fee for the end user. \n\n8.Standard architecture of GAChain application: self-independent development framework, development language, and database components; easy operation for all users of GAChain to implement application development, testing, deployment and data storage.\n\n9. Integrate the traditional / existing system with GAChain: zero code modification; low energy consumption of probes; fast-gained advantage of blockchain.\n\n10. Data storage selectively in blockchain: critical data can be stored in chain; others can be hash-encrypted, while the hash values stored in chain, and data can be stored locally and related to hashed values.\n\nGAChain VS Others\nToday, most of the blockchains have a lot of problems, such as reducing the transaction efficiency to gain the data security. \n\n![](https://cdn.steemitimages.com/DQmYzwe8XMeydMMXcZMGCW92grK9ufcgH2ZkY35pF7J7ArZ/image.png) \n\nThere are a lot of obstacles to implement the blockchain technology into traditional applications.  \n\n ![](https://cdn.steemitimages.com/DQmdFzpCFnCnjjoqXUSx2ZREAXLXRmWDpdxj1tZNQTkvdmD/image.png)\n\nBlockchain technology has been developed for a decade, but there is still no much practical application or projects integrating with traditional industries. \n\nThe above-mentioned seven problems are the main causes of the failure of traditional blockchain, and GAChain have resolved these problems. \n\nTraditional Blockchain \n\n1.\tFocus on the cryptocurrency value \nThe blockchain industry should focus on the technology itself and avoid the emergence of fake and pyramid cryptocurrency, for promoting the healthy development of the blockchain industry.\n\n2.\tTransaction Fee\nIn a traditional blockchain, user needs to spend tokens to complete a transaction, which significantly increases the cost of transaction.\n\n3.\tLow Efficiency \nThe low performance efficiency and insufficient processing capacity are a headache for the current blockchain industry andthe development of blockchain performance depends on the expansion of memory.\n\n4.\tUncontrollable Data Sharing \nToday, the blockchain industry faces problems of expensive construction cost, operation and maintenance cost, complicated management, unstable interface, bad data accuracy and low transmission security.\n\nGAChain\n\n1.\tTechnology-oriented\nGAChain is a technology-oriented company, whose founders are consecutive successful entrepreneurs in blockchain industry, with 30+professional employees, 50k active users and 11 practical (ongoing and under negotiation) projects. GAChain dedicates in building a blockchain platform that owns sovereign hierarchical management ecosystem, realizing decentralization and centralization management in transaction.\n\n2.\tZero Commission \nUsers(to C user) of GAChain do not need to pay tokens for using GAChain Apps, which is similar to the regular Apps, enabling GAChain applications to achieve large-scale expansion.\n\n3.\tHigh concurrent  transaction \nGAChain utilizes Full-Node and Sub-Node separation architecture combine with database, making reading and imputing much faster. The sub-node carries the transaction process, and the full-node carries disaster recovery and the datasynchronization.\n\n4.\tControllable Data Sharing\nThe data sharing of GAChain realizethe cost reduction of IT construction and maintenance; guarantee the accuracy, security, tamper-proof and traceability of data.\n\nIndustry solutions apply by GAChain\n\n![](https://cdn.steemitimages.com/DQmRiwEQCz7Sfq43zG7qQJsxqeVgqFf7WVQQvJp6ay5jF76/image.png)\n\n1. International cross-border trade solutions\n\n![](https://cdn.steemitimages.com/DQmWo39k44m7S5erKQtgMiqGoFkjvidBSN2x293deB6PttW/image.png)\n\nUsing blockchain technology to improve cross-border payment efficiency and security will greatly promote the development of international trade and have a profound impact on the industry.\n\n \n\n2. Property rights management\n\nThe problem of copyright rights has always been a headache for inventors and developers.\n\nThe blockchain technology can be applied to the property rights copyright management. As long as the identity verified, the user identity will be permanently stored on the chain.
