"The meta universe is established only when data becomes an asset." Xiao Feng said.

Second, the meta universe is not just AR and VR. At present, many businesses have launched cool meta universe concepts. In these schemes, it seems that the virtual world entering with VR glasses is meta universe. In Xiao Feng's view, the underlying logic of the meta universe is a digital asset that can confirm the right. The world constructed by Ar and VR can become the carrier of digital people, but they cannot be said to be the meta universe.

Third, the meta universe does not take the flow mode. How the metauniverse develops, the most important thing to observe is the blockchain. According to Xiao Feng's observation, blockchain can be described as "every user is true love", and the business conversion rate is very high. That's why a blockchain enterprise with only one tenth of some apps per month can have a valuation close to the latter. Therefore, he judged that metauniverse will not follow the traffic mode.

"The meta universe will have new playing methods and new models. To layout the meta universe, you might as well start with building the structure of the meta universe." Xiao Feng said.

Jia Bo, chairman of Dobe group, said that the "Bund yuan universe center" space will regularly hold theme salons every week to share industry trends, cutting-edge products and cutting-edge technologies, so as to build it into a "new highland" of the meta universe era with wisdom collision and agitation, so as to help yuan universe better connect with industrial forces and release its economic value.

On the same day, Dobe group, Wanxiang blockchain laboratory and Shanghai Teddy were signing a memorandum of strategic cooperation. The three parties will continue to make efforts to pool talents and technologies in yuancosmic related industries, set up yuancosmic investment fund, and regularly hold yuancosmic concept exhibition and theme scene experience activities in yuancosmic center on the Bund. It is reported that the three parties will also jointly hold the first Shanghai Yuan universe Expo within this year.

Based on Ethereum ecology, to improve performance within the limit of "Impossible Triangle", the current path has been clear. The first is layer1, that is, other public chains share the data pressure of Ethereum.

One of the main trends in 2021 is the increase in the use of many layer 1. This field is currently dominated by Solana, avalanche, Terra and binance smart chain. Each chain has a growing ecosystem with a value of more than $10 billion.

The second is layer2, which is based on the Ethereum main network, but transfers the settlement to the layer 2 network to improve efficiency. This is also the direction that Ethereum is working on. Layer2 is often called rollups because they "summarize" or bundle transactions before sending updated transaction data back to Ethereum and execute them in a new environment.

As for the most critical data verification link of blockchain, layer2 currently has two technical solutions, one is called "optimal rollups" and the other is called "ZK rollups". Both technical routes have teams developing corresponding networks and ecological support, such as arbitrum of "optimal rollups" and dydx of "ZK rollups".

Between layer1 and layer2, there is another scheme called "side chain", which is partially compatible with Ethereum main network, but does not belong to layer2. They are specially used to deal with the excess capacity of Ethereum, rather than compete with the whole Ethereum, and host Ethereum applications in a complementary manner.

In 2021, a side chain named "polygon" attracted people's attention. At present, polygon's side chain is an industry leader with a value of nearly $5 billion. Its ecology has deployed more than 100 defi and game applications, including the most mainstream AAVE and sushiswap.

Cross chain bridge

Starting from the most active users of defi, according to the statistics of defi Lama, the lock up volume of defi on Ethereum has exceeded US $100 billion, and other public chains such as BSC, Solana and avalanche have also attracted nearly US $49 billion, becoming a very active financial scene.

Although many public chains have large-scale data, different chains are like data islands, and assets on different chains cannot be freely exchanged. In addition, many emerging public chains are not as developed as Ethereum and lack many infrastructure, such as stability currency, NFT games and so on.

Therefore, assets in other chains need to be introduced into their own public chains through cross chains. In the current common cross chain methods, in addition to cross chain withdrawal in centralized institutions such as exchange wallets, the most common is various decentralized cross chain asset bridges.

For the cross chain bridge, the most important issue is how to reach a consensus, which is largely related to the safety of investors' managed assets. At present, the cross chain bridge of centralized exchange is the most convenient cross chain bridge for users, but the cross chain bridge of centralized exchange has the problem of single point of failure, In addition, the current cross chain bridge is still gradually developing in the direction of unmanaged, in order to further ensure the asset security of users.

DAO

The full name of Dao is "decentralized autonomous organization", i.e. "decentralized autonomous organization", which is an organizational form trying to get rid of the traditional bureaucratic management mode and complete independent operation with blockchain technology.

Decentralized autonomous organizations (DAO) can use blockchain based governance to achieve individual global coordination. Dao can be used for many purposes, including managing the operation and capital of blockchain projects (makerdao), managing the investment capital (the Lao), managing the use of game assets (YGG Dao), coordinating friends with benefits, or coordinating the purchase of assets (constitution Dao).

The number of Daos included in deepdao website has reached 187, with total assets under management of more than 12 billion US dollars and more than 1.6 million members. Although in the blockchain field, this is not a huge data. However, institutions including Sequoia Capital began to pay attention to this new term.

Encrypted VC transformation

The market value of cryptocurrency officially exceeded US $2 trillion in 2021 and has now reached US $2.5 trillion, an increase of 175% over the beginning of the year. With the explosive growth of market value, the financing in the field of encryption is also rising rapidly. According to statistics, in 2021, the encryption industry publicly disclosed 1529 primary market financing, with a total amount of about US $32.6 billion, a year-on-year increase of 814.2%.

However, equity financing in the field of encryption is different from other fields. Under the "vie" framework, the main capital exit channel of traditional VC is for enterprises to land in the secondary market for IPO. However, the blockchain field comes with a new financing mode ICO (prohibited in China). The key difference of this decentralized financing mode is that users can participate in the growth of the community at an earlier stage. Under the traditional venture capital mode, ordinary investors have the opportunity to share the growth dividend of the enterprise only after landing in the secondary market.

In the field of encryption, firstly, the concept of "company" has been weakened. Due to the existence of "Web3" and "Dao", communities and organizations are more mentioned. Users naturally have a sense of distrust of the centralized platform.

The hottest project in the encryption community in the past two weeks is called "opendao", which is a project imitating the head NFT trading platform "opensea". The reason why the project can be hot comes from the dissatisfaction of encryption players with "opensea". Recently, it has been reported that a new round of financing is being carried out and IPO is being prepared. The idea of "openda" is not the same as that of the current "opensea" platform, but it is not the same as that of "openda" users.

At the end of 2021, there was a debate on "Web3" in the encryption community, including Elon Musk, chairman of Tesla, and Jack Dorsey, former CEO of twitter. During the debate, they pointed the contradiction to the venture capital institutions in encryption finance and believed that VC had seized too many interests.

In 2021, an investment institution in the form of "Dao" also appeared. This organization includes highly influential and deep-rooted investors in the technology field in the community, and the performance of the projects they incubate even exceeds the achievements of some traditional VC.

Since 2020, more than 600 industrial policies related to blockchain have been issued all over the country. At present, 29 provinces and cities mentioned in the "14th five year plan" to vigorously develop blockchain technology and overall supporting implementation policies.

According to incomplete statistics, at present, there are 97000 registered blockchain related enterprises in China, which are distributed in coastal and economically developed areas. Guangdong Province has the largest number of blockchain enterprises, about 34000. At present, blockchain enterprises have spread all over the country, forming the Bohai Rim gathering area with Beijing and Shandong as the main body, the Pearl River Delta gathering area represented by Guangzhou and the Yangtze River Delta gathering area represented by Zhejiang and Jiangsu.

"From 2017 to 2020, the global compound growth rate of the blockchain industry was 73.2%, and China's compound growth rate reached 83.5%, higher than the global growth rate." Zhu Yedong introduced that at present, the blockchain industry map has formed a very perfect industrial distribution, including pan finance, government affairs, people's livelihood, certificate deposit, agreement, transportation, etc. The business and technology ecology of the whole industry chain is formed from the process, bottom chain, technical service support, bottom chain baas, privacy computing, hardware, related distributed storage and security.

There is no doubt that metauniverse and NFT have become the hottest applications of blockchain technology in 2021.

Metauniverse has reliable economic system, virtual identity and assets, strong sociality, immersive experience, open content, CO creation and other characteristics.

Zhu Yedong pointed out: "Blockchain technology provides a decentralized clearing and settlement platform. The emergence of smart contract, difi and NFT ensures the asset rights and interests and circulation of metauniverse. Games provide interactive content for metauniverse and realize traffic aggregation. Roblox has built a template for this track. The upgrade of 5g network ensures the transmission rate of information. VR and other technologies provide users with a more immersive experience, Different from market cognition, I think metauniverse is not an upgraded version of the game, but the integration of band technology (that is, the four technical pillars of building metauniverse - blockchain, game, network and display). "

NFT, which supports the mapping of meta universe virtual assets to real assets, also has explosive growth in 2021. In 2020, the top three application fields of NFT in the world are virtual world, art and games, accounting for 25%, 24% and 23% respectively. In the third quarter of 2021, the proportion of collectibles rapidly increased to 66%, art exhibitions accounted for 14% and sports accounted for 7%.

Zhu Yedong believes that NFT is expected to shine in the era of meta universe. NFT has unique advantages in right confirmation trading and is expected to become an important support of meta universe. In addition, NFT is expected to inject new vitality into the development of cultural and creative industries. The application modes of NFT are gradually diversified. The change of commodity service mode has changed from a single consumption attribute to a dual attribute of consumption assets. NFT will also become a self proven symbol, which is actually a digital certificate. The integration of financial attribute language NFT will become a trend in the future. NFT can be used as digital authentication of various certificates.

Zhu Yedong predicts that there will be seven trends in the development of the blockchain industry in 2022, including the further increase in the difficulty of data acquisition; Financial technology supervision and disposal will be strengthened. Whether technologies such as privacy computing and blockchain can support the improvement of data governance mechanism and strengthen data privacy protection will become a development hotspot; The banking and financial sectors further dominate the blockchain market.

In addition, with the intensification of international competition, it is urgent to have independent and controllable key technologies; Digital economy and virtual world are highly valued; Industrial enterprises' data security and privacy protection in production have become the main demands of industrial enterprises on the chain; Under the double carbon target, the green management of enterprises is moving towards high-quality development.

It should be noted that the current NSB file is an updated version of the file released earlier this year. According to the document, India hopes to develop a national blockchain platform to further use blockchains in various sectors. Therefore, meity hopes to establish a "national blockchain framework" (NBF), because a "geographically distributed national shared infrastructure" with nodes distributed all over India is necessary for the country to benefit from the blockchain on a large scale.

The document states that the national blockchain infrastructure will be used to provide blockchain as a service. It added that the development of NBF will require cooperation between academic institutions, governments, start-ups and industries. Initially, NBF will only be used in the field of e-government, and over time, it will transition to a broader use case.

The document states that it "describes the overall vision and development and implementation strategy of the national blockchain platform, covering technology stack, legal and regulatory framework, standard setting, cooperation, human resource development and potential use cases". It added that meity would work with other ministries and other stakeholders to ensure the implementation of the strategy.

Although the document provides a broad view of the Indian government's blockchain ambition, it does not set specific goals or implementation timetable. However, it serves as a guide for government and industry stakeholders. When cryptocurrency is under the regulatory cloud, it also brings vitality to India's blockchain community.

Finally, India's planned cryptocurrency bill has been included in the agenda of the current parliamentary session. Since the draft has not been published publicly, it has triggered many speculation about its possible impact. But the goal of the bill is to ban all private cryptocurrencies. The latest report shows that the government will regulate cryptocurrencies as assets rather than ban them completely, which injects a glimmer of hope into the cryptocurrency community.

Gamers can create digital assets (non homogenous tokens, also known as NFT) through the sandbox game maker, upload them to the store, and create a game experience through simple drag and drop. Then, through the advantages of real ownership, digital scarcity, profitability and interoperability brought by blockchain technology, sand will attract more encrypted and non encrypted game lovers and bring the blockchain into the mainstream game world.

For example, in the traditional insurance claim settlement, the insured must first apply for medical records from the hospital and then submit them to the insurance company. In order to verify, the insurance company has to spend time and labor cost to check with both the hospital and the insured. It takes a long time for the insured to get the claim settlement after all these procedures are completed, If the medical records are put on the blockchain, because the information stored in the blockchain can not be tampered with and mutual distrust is eliminated, the insurance company can immediately start the claim settlement, making the claim settlement more efficient and saving costs.

In the tourism industry, people now like to book hotels and flights through a third-party platform, for which additional commissions need to be paid. However, there are often situations such as no room or price increase after arriving at the hotel, where relevant parties shirk their responsibilities and some comments are fake. Based on the characteristics that cannot be tampered with, the blockchain will undoubtedly provide the best solution to these difficulties, Every user in the database can upload and obtain tourism data. Once a transaction occurs, the blockchain will record relevant information. The whole process will be more transparent and can effectively eliminate the dilemma in traditional tourism.

In addition, the application of blockchain in the whole supply chain will solve the mistrust between suppliers. In the food industry, blockchain can make the whole process of food birth transparent and effectively improve food safety.

Some people say that the invention of blockchain will be greater than the Internet. Now there is a blockchain technology frenzy all over the world. Blockchain applications have been extended to many fields such as digital finance, Internet of things, intelligent manufacturing, supply chain management and digital asset management. At present, many countries around the world are accelerating the development of blockchain technology
