① What technology development is needed for blockchain

What technology development is needed for blockchain:
1. Blockchain theory: Blockchain developers must understand Being familiar with the theoretical knowledge of blockchain is the most basic requirement for a blockchain developer. The content includes blockchain network architecture, decentralization and other related application technologies. Expanding technical theory is mastery of Ethereum development.
2. Smart contract: Smart contract is a string of codes that blockchain developers need to write in blockchain programming language. It is a trust mechanism developed after imagining logic according to different scenarios, aiming to eliminate the intervention of third parties. Create an efficient and high-trust blockchain network. Blockchain developers need to realize automatic execution of this string of code, and the operation effect is irreversible.
3. Cryptography: Many blockchain application scenarios have high encryption, and point-to-point encryption mode is a characteristic of cryptography. By studying cryptography, blockchain developers understand encryption concepts such as wallets, keys, and a wide range of encryption and decryption technologies
4. Distributed architecture: Blockchain developers must understand the functions of distributed architecture and networks . Decentralized network is the foundation of the blockchain architecture. The transmission of information in the blockchain network must follow a decentralized approach so that everyone can enjoy the same network rights.

② What is the Metaverse and what are its core technologies

The Metaverse mainly has the following core technologies: First, extended reality technology, including VR and AR; second, digital twins can The real world is mirrored into the virtual world, and the third is to use blockchain to build an economic system. The metaverse cannot simply be equated to video games, nor can it be equated to the virtual world. It is a creative play, open exploration and connection with reality.

With the explosion of the concept of the Metaverse, virtual digital humans have once again become the focus of public attention. Recently, A-Soul, the leading domestic virtual idol group developed by ByteDance and operated by Lehua Entertainment, caused a chain reaction due to the suspension of its members, bringing the virtual idol industry and its ecology to the attention of all walks of life again. With the fermentation of the idol group A-Soul incident, other virtual people who are one of the investments of the Byte family have also been pushed to the forefront.

It is understood that at the beginning of this year, ByteDance invested in "Li Weike", "Li Weike" and the team behind it: Hangzhou Li Weike Technology Co., Ltd. has also received much attention from the industry and media. focus on. Recently, Hangzhou Li Weike Technology Co., Ltd. launched two new virtual human characters: Lingxia and Xiaoke. The company stated that the new characters, together with Li Weike, will eventually be implemented in AR glasses products.

③ Technical innovation of CNFS

With the popularity of words such as "blockchain", "NFT" and "metaverse", some people have fallen into the trap of desperately seizing the opportunity to get rich. Amidst the craze, another group of solid people are focusing on the underlying technology. At this time, distributed storage entered their field of vision. There are already some distributed storage technologies, so are there any more efficient and secure ones?What about storage method? CNFS came into being.

CNFS (Container Net File System) is a distributed file system with an integrated protocol stack. It was founded by the CNFS Protocol Laboratory in 2019 with the goal of creating a more open, fast and secure Internet. . CNFS connects all computing devices to the same file system to achieve a globally unified all-powerful storage system.

"Hot" data distributed storage technology is one of the most core technologies. Hot data is a commercial high-frequency data flow requirement. Compared with ordinary cold data, hot data has higher reading and writing frequency and greater demand for bandwidth resources. Different from the append information mode, every read and write to CNFS is a new data entry. This ensures higher utilization of unit storage and better income for miners. In this way, CNFS allows storage hardware resources distributed around the world to be effectively shared. CNFS realizes the ultimate goal of sharing storage resources and allowing the value of data to be truly realized, thus opening up a golden era of national storage mining. In actual tests, high-frequency storage of hot data can bring miners several times more revenue than static data storage.

Not only that, CNFS allows NFT to better exert its permanence and sustainability. NFT has uniqueness and non-interchangeability that homogenous tokens do not have, but it also has some storage disadvantages. Since large files cannot be stored on the chain, pictures, videos and other files corresponding to NFT can only be stored off-chain, and only the hash value data of these files are stored on the blockchain.

Although WEB3.0 can use a decentralized approach to maintain information consistency. WEB3.0 interacts with information on the website in real time with information on other websites, and integrates and uses the data to achieve information synchronization, but it still does not solve the problem of on-chain storage.

CNFS can make use of "hot" data distributed storage technology with the help of WEB3.0, cloud computing, blockchain, and IT core technologies to create a fragmented and scalable distributed database. , the data is completely and permanently stored on the chain.

Having written this, some people may be thinking, what’s the use of just saving? NFT is not safe at all, even Jay Chou’s NFT can be stolen. NFT cannot develop further without solving its own security risks. Of course, CNFS has also considered the issues that everyone is considering. At the data security level, CNFS has been transformed for metadata nodes to enhance the system’s defense capabilities. At the same time, the function of traceability analysis of attack paths has been added, and the best defense has been carried out by enhancing self-protection and active attacks to isolate factors that may cause risks. It achieves absolute security on the chain while saving the data on the chain.Complete. Through CNFS's distributed storage technology and protective measures, it will be possible to achieve the accessibility and uniqueness of stored NFT data, and realize long-term distributed data storage, retrieval and docking storage transactions.

CNFS serves as The distributed network protocol stack has not stopped at its current achievements and is still exploring potential application areas, such as distributed medical care, distributed new energy, distributed Internet of Things, etc. The goal of CNFS is to activate more application scenarios, and then play a practical role in more fields.
