In the last article, Sanlin wrote about how the mainstream NFT digital collection IP in Europe and the United States – Boring Ape became popular all over the world. A friend left a message saying that he did not understand it very well. This article will take the opportunity to introduce the domestic NFT market and help you clarify the meaning of several hot words in the blockchain field.
Sanlin will clarify the concepts of blockchain, NFT, Web3 and meta universe in the first half of the article, and introduce some mainstream platforms of domestic digital collections and their future development prospects in the second half of the article. The article will try to reduce the technical description as much as possible, and try to explain these nouns in more popular language.
The Financial Breakfast Science and Technology column will continue to focus on cutting-edge technology, continue to track the latest developments in the blockchain field for everyone, and bring industry analysis. Welcome to continue to pay attention. If readers are interested in science and technology topics, they can also leave a message in the comment area, and we will select some for interpretation in the subsequent columns. Without much talk, the text is open.
Blockchain as the underlying technology
Before introducing all concepts, it is necessary to put the blockchain first. As the underlying infrastructure of NFT, Web3 and the Metauniverse, the general explanation for the composition of the blockchain system is that the blockchain is composed of data layer, network layer, consensus layer, incentive layer, contract layer and application layer. The technical foundation is open source, and the data is open to all.
However, this explanation does not seem very easy to understand. To facilitate understanding, Sanlin tries to simplify it. We can regard blockchain, a huge database system, as a world map:
There are blocks of land on the world map, and the blockchain database can also be divided into blocks;
Suppose that a small number of people live on each land, corresponding to a certain amount of information in each block;
Land and land are connected by sea, and blocks are connected by servers (called nodes);
Without the connection point of the ocean, the land and water cycle cannot be completed and the world cannot operate; Similarly, without these servers, there would be no place to store and circulate the information on the block.
At this point, the composition of the blockchain can be roughly simplified as: data+server. As long as we are willing, individuals/organizations/enterprises/even countries can theoretically store all data in such a database as blockchain. So why do we want to store the existing data on the blockchain? Based on what advantages do countries vigorously develop blockchain technology? How can blockchain be applied in the future?
Based on the introduction at the beginning, we already know that the blockchain database is connected by servers. It is not difficult to understand that in the world of Web 2.0 (the Internet protocol currently used), computers and mobile phones are connected based on servers. The difference is:
The existing network protocol is to partition massive data and store it in different servers. If part of it is lost, the data will be incomplete and easy to tamper with; While all information of the blockchain system has complete records in each server, data synchronization, equal status of each node, damaged data loss of one node, and complete viewing of other nodes.
Not only to prevent loss, but also because the information of the blockchain database can be shared synchronously at each node, it is very difficult for a single node to fabricate or tamper with information, and it is futile to tamper with one of the massive servers in the world.
Based on such storage and consensus mechanism, the future application scenarios of blockchain are highly anticipated. For example, for data storage in financial industries such as banks, insurance companies, equity registration and stock exchanges, blockchain technology can be used to improve risk resistance. For example, government departments with national information, such as public management, energy and transportation departments, can use blockchain technology to enhance data processing and government work efficiency.
In addition to these application scenarios, a series of technologies have been extended based on blockchain, and industry boundaries are also expanding. NFT, Web3, and the meta universe can all be seen as derivatives of blockchain, the underlying technical architecture.
NFT, Web3, Metauniverse
The full name of NFT is non homogenous token. Cryptocurrencies can be divided into two types: homogeneous tokens and non homogenous tokens. The former means that tokens can be traded with equal value. For example, if you have 100 pieces of USD, each piece has the same value, and non homogenous tokens means that we have 100 pieces of notes, but these 100 pieces of notes are different in length and value, which is called non homogenous tokens.
In the NFT field, there are no two identical tokens, just as there are no two identical eggs in the world. We cannot say that this NFT is of high value, and that NFT is of low value. Van Gogh’s works have no market earlier, but we cannot say that it is of no value.
