Filecoin will launch an EVM-compatible Filecoin virtual machine in phases, and the first phase version will be launched in the fourth quarter of 2021 2021-11-12 Filecoin will launch the Filecoin Virtual Machine (FVM) to introduce the programmability of smart contracts to the Filecoin network. The native code language of FVM is WASM (WebAssembly), which enables Web2 developers to invest in the development of Web3 faster. In addition, FVM will first achieve EVM (Ethereum Virtual Machine) compatibility, and Solidity developers can use Filecoin faster Deploy smart contracts. FVM will be launched in phases. The first phase is expected to launch non-programmable FVM on the Filecoin mainnet in the fourth quarter of 2021, which will only run system actors. The second phase introduces protocol forks (the first quarter of 2022), and introduces preparatory adjustments before developers can program, including gas mechanism and structural adjustments. The next two phases will introduce programmability, redesign the system role and deeper protocol changes to make it easier to program the system role, which is expected to be completed in the second quarter of 2022.

1. New Track of Filecoin Mining With the advent of the era of 5G, the Internet of things and big data, human data is growing rapidly at the rate of doubling every 18 months. The need to store these data, remove duplicate data and search has become increasingly important. A large market of several trillion dollars has been formed, which requires a safe, reliable and huge infrastructure. At present, the most advanced and leading technology in this track is IPFS or Filecoin, which overcomes most of the weaknesses of data storage technologies such as a centralized database in the past. In particular, it provides data security to blockchain distributed nodes and achieves the self-control of data producers. Therefore, IPFS is known as the "file system that will never disappear". The main network of Filecoin has been launched for three months, and the data stored on the whole network has exceeded 2EB, equivalent to 200 Google data. Filecoin is a star project in the coin circle in 2020. According to the data from BlockVC, there are at least 200 to 300 Filecoin miner sellers in China, and the sales volume of several leading manufacturers even exceeds 1 billion yuan. The cost of the mining machine was blown to about 100000 yuan.

Ⅰ. Mining Structure Interpretation of Filecoin Similar to bitcoin, Filecoin miners compete with each other to mine and create blocks. Compared with bitcoin, Filecoin's mining ability is directly related to active storage. The system aims to create an incentive structure for miners to accumulate as much storage space as possible so that they in turn rent the storage space to customers. The storage and retrieval of data on Filecoin protocol are directly related to the mining mechanism of the whole system. Filecoin aims to adapt to a decentralized and verifiable market structure, which has two main components: the retrieval market and the storage market. The retrieval market exists under the chain, while the storage market is based on the chain.

1. Filecoin network The Filecoin network is a distributed peer-to-peer network consisting of Filecoin nodes participating in different ways. Peers communicate through secure channels, they are used to distribute information to the network, transfer data between them, and discover other peers, maintaining a well-connected swarm where information such as blocks and messages is available even in thousands of In the case of rapid flow of peer participation.

In recent years, some challenges faced by cloud based storage providers have become increasingly tough. These difficulties include lack of trust, unreliable security, limited connectivity, poor scalability, and excessive reliance on centralized providers. For example, system hacking and accidental data loss are common problems in the existing cloud storage ecosystem. Filecoin proposes solutions to these problems. As a cloud-based distributed storage network (DSN) based on InterPlanetary File System (IPFS), it interacts with Ethereum blockchain and uses its unique utility token FIL.

The Internet is constantly iterating and upgrading, and I believe that almost everyone has heard of the concept of Web3.0. Web3.0 is a very old topic. Since 2006, the term Web3.0 has received more and more attention and is also the focus of more and more controversies. This phenomenon has continued so far. Yesterday, Brewster, the founder of Internet Archive, and Brewster, founder of Internet Archive, and Marta, Chairman of the Filecoin Foundation, co-hosted Forkast's podcast, and discussed in depth how they use decentralized networks for Future users retain the Internet and think about Web 3.0. Co-hosted Forkast's podcasts, and discussed in depth how they use decentralized networks to preserve the Internet for future users, as well as their thinking on Web 3.0.

As the rewards of the FIL mainnet continue to decrease, the daily currency production this month has been revised to 0.027 FIL. Please understand that the number of coins produced by the product will be revised at the beginning of each month.

Blockchain technology will not only thoroughly change the financial or healthcare industry but also completely change many aspects of business, government and even our personal life. The problem is that there is too much speculation and misunderstanding. It is hoped that everyone can understand the basic knowledge of what blockchains are and how they work, even without a priori necessary technical knowledge.
