Two blockchain branches two real Societies

        The attention to blockchain varies from group to group. For example, the enthusiasm of capital and mining machine manufacturers for digital currency, the vision of the development community for a decentralized world, and the expectations of industry and service providers for alliance chain and encryption technology. From the perspective of technology development and practice, blockchain is integrating with Internet of things, artificial intelligence and other technologies in different ways, connecting with business logic, institutional rules and other mechanisms, enriching the digital economy and empowering the real industry. In the future, the digital twins of the physical world will gradually improve one by one, and these two worlds together constitute the future real society. This society represents the broad public opinion, efficient resource allocation and sustainable energy-saving development. We call it "smart society".
        The advantageous characteristics of blockchain transparency, traceability and tamper resistance can provide technical support for widely involved social governance and maintain the fairness, transparency and rationality of social operations. For example, the bitcoin system (blockchain 1.0) refers to the organization and operation of human society and introduces a consensus mechanism. Consensus is a typical sociological concept. On the basis of 1.0, Ethereum (blockchain 2.0) has added smart contracts, that is, transaction contracts in the computer world, so as to expand the application of blockchain from digital currency and digital payment to other financial and non-financial fields. Blockchain is not a technology. It is the integration of P2P dynamic networking, distributed accounting, consensus algorithm and other technologies.
        Distributed structure is the core and basic framework feature of blockchain. Decentralized data storage makes data safer and more reliable, and provides practical and feasible solutions for trusted data property verification and extensive digital collaboration. Governance architecture is the top-level design of blockchain. As far as the public chain is concerned, tokens, governance rules and contract mechanisms have given it free networking and a high degree of autonomy. These things are constantly improving, trying to build an online kingdom of "common ownership, co construction, CO governance and sharing", and bring money, productivity and consumers to this kingdom. Secondly, at the operational level, consensus algorithms such as POW and POS and constraint incentive mechanisms not only ensure the fairness of task and resource allocation, but also comply with the principle of incentive compatibility, which is conducive to attracting external computing power; The use and payment design of "highway payment station" avoids the abuse of infrastructure and is an important cornerstone of market economy.
        In addition, anti inflation arrangements, exchanges, consumer tokens, etc. have created a positive thrust for the value anchoring of tokens and the attraction of public chains. Once there is a real digital ecosystem, the public chain platform is a more real Kingdom than the game world, or it can be called "online platform organization" first. From this point, we can understand why the price fluctuation of bitcoin, which lacks industrial support, is unstable. Now it is more like the stock of an enterprise than the national currency. At present, the public chain is in the early stage of development, with hot technology and cold application, and "killer" applications have not yet appeared. However, thanks to the technological proving ground of globalization such as Ethereum, blockchain technology has become increasingly mature, and the road from virtual to real is gradually clear.
        Blockchain projects connecting the real economy are increasing year by year. For example, the charity bitgive announced that it would apply blockchain technology to establish an open and transparent donation platform, and the use of donations would be fully open to donors and the public; Ujomusic, a music platform, has established a music copyright management platform with the help of blockchain, so that creators and consumers can establish direct contact; The municipal government of Lugo, Spain, has established an open and fair voting system by using blockchain. The independent implementation of blockchain technology has made the Ethereum platform smell the crisis. In November, 2019, the founder announced the official launch of Ethereum 2.0, replacing the main force of high energy consumption POW with a more efficient POS consensus, and introducing the fragmentation and multi consensus mechanism, trying to improve the problems of low processing capacity and poor expansibility.
        In the future, blockchain must learn from each other. Blockchain will participate in digital transformation as an integral part of credit system, it system and digital infrastructure, or one of the main technical supports. Alliance chain is a branch of blockchain derived from the deficiency of public chain. Before introducing the alliance chain, let's first look at the main problems of the public chain:& bull; Efficiency is sacrificed for fairness. The consensus mechanism better guarantees the principle of fairness, but greatly reduces the processing speed and cannot meet the medium and high frequency trading scenarios in real society& bull; Decentralized diseconomy. POW consensus algorithm brings huge computing power abuse and power consumption, and distributed accounting takes up too much storage resources.
        • Limitations of trust. Blockchain can only trust the "own" data, and can't do anything to fake or tamper with the source end under the chain. At the same time, the public chain has no identity system, which is easy to be used as an illegal zone for money laundering and fraud. It needs to cooperate with other trust mechanisms to create a credible environment. In this context, some large institutions introduced the idea of blockchain into the reform of IT systems, and the alliance chain was born. Compared with the public chain, the alliance chain has an identity system to ensure contract privacy, which is closer to the production scene of the real society. Alliance chain is a common governance form of access system, which has three elements: trusted property registration, trusted identity authentication and trusted data nodes. It is generally designed by industry alliances or technology companies, and has the characteristics of high performance and high practicality.
        The alliance chain has channels and identity authentication facilities, so that the data seen by each type of node can be different. This is similar to the traditional enterprise level system, that is, restrict the users who enter the system and set different permissions. The controllability of the alliance chain is also better. In case of major mistakes or mistakes, it can be controlled through the alliance governance agreement. Alliance chain has become the main route of blockchain technology from virtual to real, especially in the field of multi-party cooperation in the distrust environment such as cross-border clearing and supply chain management, which provides a new way to establish a cross organizational trusted cooperation network. Because the business logic of each vertical field is different, it is bound to be a long exploration process for the public chain to build a digital society from top to bottom.
        Industrial docking based on "blockchain +" component technology integration seems to be more effective. In recent years, the development and rise of blockchain projects have formed independent chains. If they are isolated from each other and become isolated islands of information, network effects cannot be formed. Therefore, cross chain technology, which allows different chains to communicate with each other, has received high attention. In the future, more large-scale alliance chains may be established around vertical industries, and more blockchain general service platforms may be built around specific fields. What will these large alliance chains and public service platforms look like? The hyperledgerfabric architecture of the super ledger brings us imagination.
        This is an extensible architecture and a trusted blockchain platform. It is characterized by Multi Chain and multi-channel, and all participants will have known identity authentication. Multi channel function, which can realize multi service isolation. Participants can create channels (sub chains) belonging to small groups in groups. The purpose of creating channels is to limit the scope of information dissemination and associate them with a certain ledger. Each transaction is associated with a unique channel, which can clearly define which members can know the transaction. In the future, with the continuous enrichment of sub chains, this alliance chain architecture will grow into a huge distributed blockchain system with embedded authentication, and its boundary with the public chain will gradually blur.
        Blockchain can be global in the scope of trust, and the future Internet may change due to blockchain. Some technical experts pointed out that the Internet in the past few decades was unreliable, unfair and lacked a trust mechanism. Because there is no email standard introduced and the key is not taken as the default setting, there have been many security problems such as large-scale spam and ordinary user identity theft on the Internet. Moreover, the storage server is owned by a few, resulting in centralization and information monopoly. If the blockchain with built-in privacy function is introduced into the Internet or the Internet of things, more high-value data will be put on the chain and online all over the world, generating more authentic digital assets, and trusted collaboration can be carried out in a wider range.
        Like nerves, once interconnected, like the nervous system, it will bring new levels of intelligence to our social development. In the future, there must be centralized and decentralized cooperation. The advantages of public chain do not have universal and necessary value in the real scene. For example, decentralization. Facing the changeable external environment, decentralized governance will reduce the responsiveness of the organization. Another example is disintermediation. The trading rules in the real world are often complex and not closed. This means that pure blockchain applications can only be applied to simple businesses or solve relatively simple and critical links in complex businesses. Complex transactions are still inseparable from the assistance of professional intermediaries.
        At the same time, going to the intermediary means that there is no third-party credit endorsement, and the risk is difficult to transfer. The public chain will give full play to its strengths in the context of transparency and fairness. With the help of public chain technology, the sharing economy can be carried out in more fields such as transportation and services, and global charitable organizations, creative communities and certification platforms will continue to emerge. Blockchain has opened up new possibilities for a wider range of global integration and collaboration. Decentralization here does not replace centralization, but includes centralization. In the public chain, each individual is not necessarily an individual, but can be composed of centralized institutions, enterprises, and a large number of individuals. Electronic identity and privacy technology is a necessary condition for the large-scale application of blockchain, and it is also the foundation of digital society.
        It is expected that many countries will use electronic identities on the blockchain in the next decade. Both did distributed identity recognition technology and the cross chain governance layer of hierarchical design indicate that the extensive interconnection of identity management is the general trend. In the future, blockchain systems are not only interconnected, complementary, but also mutually verifiable. Social evolution is moving towards a more efficient and orderly world. Looking forward to the future, under the escort of global data governance, we are expected to usher in a widely connected, identifiable and barrier free value network. Blockchain trust and institutional trust complement each other to build a more universal and efficient global trust system.
