㈠ What are TaiChiChain (TaiChiChain) board members?

The board of directors is composed of a group of board members voted by shareholders. The responsibilities of the board members are to set System operating parameters. These include:
1) Transfer and transaction fees;
2) Blockchain parameters, such as block size, block generation interval;
3) Recommendation and freezing/unfreezing parameters, For example, reward cashback ratio and freezing time, etc.
Note: The Board of Directors only sets system operating parameters and cannot directly influence the "witnesses" to package and produce blocks.
The Board of Directors currently has 11 member seats. To become a member of the Board of Directors, you need to become a member first (anyone can become a member through a wallet command). Then, votes can be canvassed, and the top 11 committee members with the highest number of votes can become council members.
You can think of TaiChiChain as an ecosystem. It is a complete closed-loop system. The entire system does not distinguish between national boundaries. In it, the top 11 users in the world based on TCC currency holdings will become members of the council. His The right is to vote to modify the parameters and some rules of the system, which can be understood as a company's board of directors.
The board members of TaiChiChain are not fixed and are updated in real time. When you sell TCC and you are not enough to rank in the top 11 in the world, you will be replaced by other users.

㈢ Re-understanding the blockchain: Enlightenments brought by more than 1,550 application cases

Author: Ran Wei

(This article is excerpted from "2021 Global Area Blockchain Application Market Report")

When we talk about blockchain, anyone who knows something about blockchain can more or less express some of their own opinions on related topics. . For example: from the perspective of technical system, blockchain is a new application of computer technology such as distributed data storage, point-to-point transmission, consensus mechanism, encryption algorithm; from the perspective of functional attributes, blockchain is decentralized, non-tamperable, and full-process. Features such as leaving traces, traceability, collective maintenance, openness and transparency.

Looking back at the history of blockchain, there is no way around Bitcoin. On January 3, 2009, the Bitcoin genesis block with serial number 0 was born. A few days later, on January 9, 2009, Bitcoin block number 1 was born. When two blocks are connected, the blockchain is "born."

The inventor of Bitcoin, whose pseudonym is "Satoshi Nakamoto", may find it difficult to imagine: In the past 12 years, with Bitcoin as the center, a huge "cryptocurrency family" has spread all over the world. The financial market set off a "big wave" that continues to this day. During this period, innovation and risks related to cryptocurrency are intertwined, progress and bubbles coexist, and pursuit and criticism coexist, and it drives government departments of various countries to continuously improve the monetary and financial systems, social governance and supervision systems.

At the same time, the blockchain that accompanies Bitcoin is also evolving rapidly, and has long gone beyond the scope of "Bitcoin's underlying technology" and has been applied to every corner of social and economic development.

So, what mechanism does blockchain work through? What are its advantages compared to traditional technologies and models? What is its application effect? In the "2021 Global Blockchain Application Market Report" jointly released by Capital Lab and Yuanwang Think Tank, we tried to provide a certain basis for the above issues through research on more than 1,550 application cases around the world in 2020 and the first quarter of 2021. Empirical answers. At the same time, based on the study of these cases, we can establish a new understanding of blockchain: blockchain is trust, blockchain is sharing, blockchain is transaction, blockchain is substitution, and blockchain is efficiency.

In the Bitcoin creation paper "Bitcoin: A Peer-to-Peer Electronic Currency System", "Satoshi Nakamoto" repeatedly emphasized that Bitcoin has the characteristics of not relying on a "trusted third party". That is the characteristic of “decentralization”.

On the other hand, the underlying technology of Bitcoin, the blockchain, is precisely designed for "trust." In other words, reshaping "trust" in the digital era is the most basic function of the blockchain, but this trust consists of trust between people and between legal entities.Converted into trust between machines, between blocks, and between nodes. Interestingly, the subsequent “smart contract” function has further strengthened this trust through its integration with the blockchain.

Identity coding and authentication are the first steps to achieve the above-mentioned trust mechanism, and the distributed identity (Decentralized Identity, DID) system is the core of it. With DID applications, everyone from individuals to organizations to IoT devices, from physical items to virtual products, can be given digital "identities" and achieve trusted interactions. It is precisely because of this that blockchain-based certificate storage, empowerment, verification, circulation, and transactions can be realized, and only then can blockchain be implemented in various industries.

Application cases from around the world show that new trust mechanisms provide new rules and motivation for social and economic operations:

l China is comprehensively promoting blockchain electronic certificates Applications such as "one fish, one code", "one fruit, one code", "one tea, one code" and other applications are driving the global Anti-counterfeiting traceability of agricultural products and upgrading of food safety systems;

l Through the combination of blockchain, big data, and artificial intelligence, the credit "portrait" of an enterprise is more accurate and can be obtained faster and more accurately. Lower-cost financing services;

l Charitable charity organizations have put charity funds "on the chain" to form a more transparent and standardized charity tracking and management system;

l Relevant cities in China have launched a blockchain-based gas cylinder product traceability management system, and the credibility of the source of gas cylinder file information and the level of gas cylinder safety management have been greatly improved;

l Germany is developing its distributed energy resources Assets establishes a digital registration system based on identity authentication to promote the development and trading of renewable energy and cope with the arrival of the digital energy era...

Among the three types of blockchain (public chain, alliance chain, private chain), alliance chain has been the most widely used. In addition to considerations of technical performance, operational efficiency, operability, expected results, etc., this is mainly because all parties in the alliance already have a certain foundation of trust. This also shows from another perspective that in blockchain applications beyond cryptocurrencies such as Bitcoin, "multi-centering" rather than complete "decentralization" is a more realistic option.

In addition, it is undeniable that unlike the proof-of-work mechanism that Bitcoin “mining” relies on, the blockchain cannot completely ensure the integrity of the on-chain data from the source in the actual application process. Authenticity. In other words, a certain alliance member or node may provide false data intentionally or unintentionally. However, with the help of the characteristics of blockchain such as non-tampering, traceability, and multi-party consensus, the alliance can deal with counterfeitingIdentify and punish accordingly, such as "kicking" the fake members out of the node. Therefore, in a sense, blockchain-based trust largely establishes alliance members’ awe for the authenticity of data and deters data fraud.

If "trust" is the foundation of blockchain applications, data sharing is the core of blockchain applications. Without data sharing, there will be no cooperation, and the practical application of blockchain will be impossible.

l The State Administration of Foreign Exchange's "Cross-border Financial Blockchain Service Platform" pilot has been fully launched, promoting foreign trade exports through information exchange between foreign exchange bureaus, taxation, banks and enterprise-related market entities. Business development;

l The "Insurance/Claims Alliance Chain" jointly established by 11 insurance companies in Taiwan has been put into operation, and each company has achieved "single application and common documents" on this platform;

l Blockchain platforms such as Contour and TradeLens are reshaping the global supply chain and providing impetus for the digital transformation of international trade through data collaboration among enterprises, financial institutions, shipping companies, terminals, customs and other institutions... .

l In China, through data collaboration, various government departments have realized "one data, one source, one source for multiple uses, one network, and full network operation";

l Through The "Judicial Chain" platform enables all types of electronic evidence to be seamlessly connected with judicial institutions such as notarization, arbitration, judicial appraisal, and courts, which improves the efficiency of the judicial system while reducing costs;

l Targeting grassroots nationwide The court's "cross-domain collaboration mechanism for trial auxiliary matters" can realize "cross-domain service and cross-domain evidence collection" between courts in different regions, effectively improving the efficiency of trial auxiliary matters and trial quality and efficiency, and reducing judicial operation costs... ….

l China's "Guangdong-Hong Kong-Macao Greater Bay Area Combination Port" project was officially launched, which can support the interconnection and interoperability of trade parties among the five major customs jurisdictions of the Greater Bay Area and become the first connected port in the Greater Bay Area , customs, logistics, enterprise, finance and other trade processes, interconnected and shared blockchain network;

l Japan's KDDI Telecom, Hitachi, Kansai Electric Power, Sekisui Construction and other large enterprises have established blocks Chain Alliance NEXCHAIN ​​to form a cross-industry real estate information sharing and management model and promote cross-industry innovation;

l The French Renault Group completed the test of its blockchain project "XCEED" for zero Sharing compliance information between component suppliers and automakers and simplifying compliance certification….

Although the above application cases in finance, government affairs and various industries are only a few typical cases, they are enough to illustrate that: on the one hand, data sharing is an inherent requirement of blockchain applications. In terms of specific implementation, everything must start from breaking down"Data islands" and "information asymmetry" began; on the other hand, the application practice of blockchain has in turn promoted cross-level, cross-department, cross-industry, cross-region, and cross-border data sharing and unprecedented cooperation.

It can also be seen from the above cases that based on the transparency, security, trustworthiness and other characteristics of the blockchain, data sharing allows cooperation that originally seemed impossible to be achieved, and more Open innovation results; data sharing can effectively improve the operating efficiency of business systems, financial systems and social governance systems; various organizations promote their own organizational changes and process changes while sharing and cooperating with external institutions.

Based on trust and sharing, "transaction" is the most intuitive and deepest manifestation of the value of blockchain applications. Currently, blockchain is opening a new chapter in the transformation of transaction models in various industries around the world.

From a functional architecture point of view, blockchain-based transactions are by no means just a change in the transaction process, but integrate the unique functions of the blockchain, which are the key to anti-counterfeiting traceability, supply and demand docking, and warehousing. Integrated integration of blockchain applications such as logistics, payment/settlement, supply chain financing, insurance, and network security.

From the perspective of application form, blockchain-based transactions transcend the traditional concept of product or service transactions and represent the realization of the value of a wider range of data in circulation.

From the perspective of application scenarios, transactions based on blockchain involve the upgrading of the physical industry, the digital advancement of the financial industry, and the innovative application of the "token economy".

In the physical industry, take the application of agricultural blockchain as an example: on the one hand, supply chain traceability based on blockchain has become an important barrier to food safety; but on the other hand, for growers or For farmers, the supply chain traceability function is far from enough. How to help them expand the sales of agricultural products and obtain more income as much as possible is the "hard truth" for blockchain technology to continue to promote agricultural development. In other industries, the same applies.

Against the above background, new trading platforms in the global physical industry continue to emerge:

l The Indian government uses blockchain platforms to help farmers in remote areas sell agricultural products to reduce the While eliminating intermediate fees, obtain higher income;

l The Swiss company Cerealia builds a blockchain-based agricultural product trading and financing platform to promote the export of agricultural products in emerging market countries around the world;

l The world's largest independent refined sugar producer, Al Khaleej Sugar Company of the United Arab Emirates, launched DigitalSugar.io, a blockchain-based sugar product trading platform, to realize spot-based international raw sugar trading;

l Ganzhou, Jiangxi Province, launched an international timber electronic trading platform based on blockchain.The whole process of timber trading will be managed on the chain, and the timber market will be provided with full industry chain services such as supervision of cloud warehouses, logistics, finance, and insurance;

l Shandong Province has launched the Shandong Internet Chinese Medicinal Materials Trading Platform, which will Realize online integrated services of quality control, transaction, payment, settlement and supervision through blockchain and other technologies;

l Weitang Town, Xiangcheng District, Suzhou released a blockchain-based pearl online trading platform, The core parameters and test reports of pearls will be uploaded to the chain for certification, and functions such as supply chain management, trade finance, smart contracts, payment settlement, and incentive mechanisms will also be added;

l Honeywell launches aircraft zero GoDirect Trade, an online trading platform for new and second-hand parts, provides a valuable reference for large manufacturers on how to apply blockchain to parts trading and circulation...

In the financial industry, blockchain is promoting the digital advancement of financial transaction business in aspects such as securities trading, asset securitization, trade financing, and cross-border settlement:

l The Australian National Stock Exchange has launched ClearPay, a digital securities trading platform based on distributed ledger technology, which can provide multi-currency, real-time DVP settlement on the same day and will replace the original exchange settlement system;

l Switzerland The company Finka has launched a related securitization token investment platform based on livestock from organic pastures in Bolivia to promote the development of the local livestock industry;

l The American company Securitize has established a Japanese real estate investment platform based on digital securities , aiming to revitalize idle real estate in rural Japan and enhance the vitality of the rural economy;

l China Postal Savings Bank and China Construction Bank completed the first cross-blockchain platform forfaiting transaction, Hua Xia Bank Kunming Branch’s first Realize forfaiting resale business in the secondary market;

l Nanjing Iron and Steel completed blockchain-based iron ore transactions with Rio Tinto of Australia and Vale of Brazil respectively;
< br /> l Baosteel Co., Ltd. and Australia's Rio Tinto completed the first blockchain-based RMB cross-border settlement transaction...

Of course, while blockchain promotes the advancement of financial transaction business, dark sides such as hype, scams, money laundering, and cyber attacks related to blockchain and cryptocurrency continue to follow. How to continue to promote financial innovation while also carrying out efficient risk prevention and control and effectively cracking down on illegal crimes is an important issue that requires long-term response. From a global perspective, China has responded with clear attitudes, strict measures, and effective measures in this regard.

The transaction changes realized by the blockchain in the real industry and financial industry are only the initial stage of the blockchain changing the traditional transaction method. "Token Economy"my)" is the higher level of the "transaction" function of the blockchain.

Under the framework of the "token economy", from electronic certificates to skill certificates, from credit records to public welfare activity participation records , from social media tracks to carbon emission reduction actions, when various data become encrypted digital proofs of rights and interests, and can be circulated and exchanged, they are given the "token" function.

Regardless of the investment/speculation craze of "Non-Fungible Token (NFT)", we can already see many early applications of "token economy" around the world:

l The HotCity project supported by the Austrian government uses a crowdsourcing model combined with blockchain and gamification tokens to encourage residents to submit heating waste heat hotspots to more efficiently meet urban heating needs;

l Ford is establishing "green miles" for commercial and municipal fleets using hybrid vehicles to help improve urban air quality;

l Weibin District, Xinxiang City, Henan Province, is building on the Merchants and enterprises issue certificates through the points system to establish a new business service platform;

l Chengdu released a blockchain-based community governance product "Chain Community", where residents can participate in volunteer services and other activities Obtain "Time Bank" points from the platform and exchange them for benefits and discounts provided by community merchants;

l Electric vehicle charging network working group of the global non-profit organization "Mobile Open Blockchain Initiative" ( EVGI) launches a global standard system for decentralized car charging technology, covering Tokenized Carbon Credit (TCC) scenarios;

l Blockchain reward platform MiL.k cooperates with Korean retailers to provide Its members provide blockchain-based points management services. Members can convert existing points into local MLK tokens through the MiL.k platform, or exchange them for other third-party points...

By As can be seen from the above cases and more, the "token economy" has several distinctive features:

The "token economy" gives asset attributes and tradable attributes to a wider range of data, and through cross- Mutual trust and circulation across domains and platforms can improve the operating efficiency of the entire social and economic system;

"Token economy" is a new process of value creation and realization, which does not necessarily use currency directly. Instead of being a trading medium, it is more embodied in the exchange, mutual benefit and reconfiguration of various elements and resources;

"Token economy" is often combined with an incentive mechanism, through the exchange of "good people and good deeds", The incentives of "good companies" and "good institutions" will effectively reshape the social value system and social credit system.

Overall, the "Token Economy" will spawn new production factors, reshape production relations, and greatly liberate social productivity; the "Token Economy" represents the evolution of the "Information Internet" to the "Value Internet" , indicating the most exciting future of the digital economy; the "token economy" based on blockchain has begun to take shape, and has begun to bring continuous and visible changes to economic operations, social governance, and everyone's lifestyle. All types of institutions and individuals should be mentally and physically prepared for this change.

Like other new technologies, in the process of application and popularization, blockchain continues to produce substitution effects in terms of platforms, media, models, methods, etc.: physical documents are replaced by electronic documents, and credit records are replaced by electronic documents. Tokens are replaced, manual review is replaced by data verification, and the city management platform is replaced by the "city brain"...

Such substitutions have become the norm:

l Argentina’s central bank has begun a proof-of-concept for a new blockchain clearing system, which may replace the existing clearing system;< br />
l Korea Minting and Security Printing Corporation (KOMSCO) expanded its blockchain digital gift certificate business to replace paper gift certificates and achieved record revenue despite a sharp decline in the issuance of banknotes and coins. Improvement;

l Courts across China have begun to use blockchain electronic seals to replace traditional paper seals in the enforcement of real estate seizures;

l The Shanghai court system is using artificial intelligence , the adoption of new technologies such as blockchain, and explore the use of digital court trial records to replace manual court trial transcripts;

l The Japanese company SUSMED launched a "Clinical Data Monitoring System Demonstration Using Blockchain Technology" pilot, indicating that the drug Or the necessary monitoring process in clinical trials of medical equipment can be replaced by a blockchain system;

l Alipay and Wukong Car Rental have cooperated to launch a "face-swiping" car rental service, which uses blockchain technology and credit-free security mode, tourists can rent a car by simply "swiping their face" and return the vehicle through mobile operations;

l Under the new crown epidemic, local governments in China have intensively launched "non-face-to-face" vehicles that combine blockchain technology ", no contact, zero errands" government service has replaced the traditional offline service method, providing a strong guarantee for the smooth progress of remote bidding, "cloud" customs clearance, financial support, resumption of work and production, etc. during the epidemic... .

In addition, we can also see that through the use of blockchain technology, various enterprise-level services are also realizing substitution and evolution: from paper contracts to electronic contracts, to program-based, Blockchain contracts that can automatically execute smart contracts. Blockchain is pushing contract signing into the era of "chain signing"; from offline human resources companies to online human resources platforms to basicIn the blockchain human resources market, global human resources services have experienced continuous changes from the 1.0 era to the 2.0 era and then to the 3.0 era.

Generally speaking, when the blockchain "invades" various industries, it will "mercilessly" delete all unnecessary links and processes, all unnecessary manual operations, and accelerate the The era of paperless, unmanned and automated is coming.

In the process of our analysis of more than 1,550 blockchain application cases around the world, words like "improve", "accelerate", "shorten", "lower", "reduce", "save", " Words such as "save" appear frequently in front of our eyes. These words show that the improvement of efficiency is the common pursuit of all parties involved in blockchain applications and is also the most direct result of the substitution effect of blockchain.

Numerous application practices are contributing to this:

l Kenyan company Shamba Records provides blockchain traceability, transaction and financing services to farmers in the country, currently covering more than 6,000 Small farmers and helped them increase their income by at least 40%;

l TradeWaltz, a blockchain trading platform invested by NTT DATA, Mitsubishi and other companies, completed a trial run, and the results showed that the platform can reduce traditional 50% of the workload of the trade process;

l Walmart Canada has significantly reduced invoice disputes with carriers by 97% through the application of the DL Freight blockchain platform;

l The State Grid Corporation of China’s power transaction certificate traceability inquiry platform has been put into operation, automating the entire authenticity review process for registered users and saving 99% of trusted manual review time;

l COSCO Shipping Lines and Shandong Port Group Qingdao Port have cooperated to launch a blockchain paperless import and delivery model, which can save customers nearly 24 hours on average per container;

l Taizhou, Zhejiang uses "materials" The "Internet + Blockchain" recycling system solves the problem of marine pollution control. Compared with traditional processing methods, this recycling system can save 94% of labor costs and 84% of operating costs...

In summary, through the joint action of trust mechanism, sharing mechanism and transaction mechanism, blockchain has formed an obvious substitution effect, improved the operational efficiency of finance, government affairs and various industries, and will Continue to create systemic change. This change is reshaping the relationship between people and machines, people and society, and people and the environment, and clearly points to three ultimate goals: efficiency, well-being, and environmental protection.
