Why did Filecoin become a hot spot in the blockchain and technology circles before the mainnet went live ? Do dozens of encrypted digital currency platforms have FIL futures listed? First, this has a great relationship with the 2017 ICO attracting the participation of top global investment institutions including Sequoia Capital; second, the famous PL official laboratory members of the project's physical landing technology IPFS are also very important. A distributed network designed to store the most important information of human society. As a revolutionary project of next-generation Internet transmission technology, it gathers high-tech industries such as big data industry, blockchain, data storage, cloud computing, edge computing, artificial intelligence, and the Internet. The most cutting-edge technology will naturally become a public chain with global consensus from the day the mainnet goes online on October 15, 2020. Filecoin is known as the blockchain 3.0 version after Bitcoin and Ethereum, and is the largest in the next 20 years. One of wealth opportunities.
1. How did IPFS come from?
It was founded by Protocol Labs in 2014. Because of the founder Juan's solid technology and grand blueprint, Y Combinator, a start-up business incubator, favors him.
A few years later, the Protocol Lab issued Filecoin, an incentive-layer blockchain project supporting the IPFS protocol. According to data, from the birth of the project to June 2017, IPFS network providers have stored more than 5 billion unique content files and data Continue to grow.

2. What is the current status of IPFS/Filecoin?
After seven years of development, the IPFS storage network has now grown into a global distributed storage option, and the Filecoin blockchain main network was officially launched on October 15, 2020.
At present, my country's blockchain and digital asset industry has always paid great attention to the progress of IPFS technology and ecology!
3. Is a distributed storage solution important?
Of course it is important.
The blockchain itself is a technology that integrates distributed storage, asymmetric encryption, and based on consensus algorithms. The distributed storage solution based on blockchain technology and the BT protocol are technically similar in that they both perform storage of the files to be stored. Fragment, and store the fragments on each node. In this solution, due to the characteristics of blockchain technology for data encryption and privacy protection, and the immutability brought by decentralization, it perfectly surpasses centralized servers.
Most importantly, many scholars believe that IPFS is the highest development form of blockchain.
4. Why is the current HTTP protocol behind?
The disadvantages of HTTP are as follows:
Inefficient structure: The structure of HTTP only allows the client and server to request and serve a single Web element at a time. This is why some web pages with multiple web elements require longer loading times than other web pages. Although HTTP can effectively move smaller files, in a world where users generate large amounts of data islands every day, HTTP has become increasingly inefficient and expensive.
Centralized network: Because Web elements and data are requested from a single host server, it makes these central servers vulnerable to DDOS attacks and data attacks. These centralized networks allow themselves to accept government or agency scrutiny. In 2017, the Spanish government responded to the Catalan independence referendum and reviewed multiple websites and apps related to the referendum.
5. Why is the future IPFS sufficiently advanced?
The IPFS model creatively avoids the shortcomings of HTTP:
Efficient structure: On IPFS, each node can provide content to the node peer or request content from the node peer. The more nodes on the network, the more efficient the data transmission. The client on IPFS does not request one Web element at a time to complete a web page, but requests multiple Web elements from multiple nodes.
Distributed network: The nodes on IPFS are allocated and have equal power, instead of a single server farm to store and transmit data. If a node is attacked or shut down, data can still be retrieved from other nodes on the network. The distributed network reduces the attack surface of censorship. In response to the Spanish government's censorship, the Catalan government used IPFS to upload previously banned websites and open them to the public.
6. What are the contents of the IPFS protocol stack?
Identity: The IPFS node receives a NodeId, which is a cryptographic hash of its public key. NodeId can help identify nodes in the IPFS network. When nodes connect, they exchange public keys and check whether the encrypted hash matches the public key. If they match, the connection is established; if not, the node is disconnected.
Network: IPFS helps manage the connection of peer nodes on its network, and provides transmission, reliability, connectivity, integrity and authenticity functions.
Routing: IPFS uses DSHT based on S/Kademlia and Coral to route information between peers.
Exchange: IPFS uses the exchange function BitSwap inspired by BitTorrent to exchange data between nodes.
Objects: IPFS objects contain data and links to other objects. IPFS uses Merkle directed acyclic graphs to obtain data fragments to efficiently compile the entire file.
File: IPFS can model the hierarchical architecture of the control file system based on the Merkle directed acyclic graph.
Naming: IPNS allows users to create readable links to their content.
7. What are the applications of IPFS?
According to statistics, in 2019, the IPFS public network has increased by 30 times. Google Chrome, Firefox, D.Tube, IPWB, Ethereum, Origin, etc. have joined the IPFS network. Today, IPFS is growing at a rate of 2.5EB/day , To store valid data for the world.
Developers continue to contribute to the open source protocol, users continue to upload files to IPFS, and dApp developers continue to use their network to store data. In just over four years, IPFS has established itself as a key infrastructure for the decentralized Web. At present, many mature applications have been implemented based on IPFS, including OpenBazaar store, Brave browser, Peerpad collaborative editor, etc.
8. What is the income of Filecoin?
Filecoin stimulates the long-term operation of nodes through storage, retrieval, and block rewards to better serve the entire network ecosystem. The total issuance of FIL is 2 billion pieces, miner rewards account for 70%, agreement laboratory receives 15%, public and private investors account for 10%, and the foundation retains 5% for ecological development.
Filecoin's issuance speed is divided into three parts: miners reward 50% issuance within six years; foundation and protocol laboratory will be linearly released within six years; investors will be distributed within one year.
9. Two market introductions of Filecoin
Storage market: The Filecoin storage market is a verifiable market that is verified by the blockchain network. In the Filecoin storage market, customers put forward the demand for storing data, and the storage supplier provides storage miners with their storage space. Storage is not a one-time service, it needs the stability and continuity of the storage party. The storage party can get rewards in three ways: transaction fees; block rewards; network transaction acceleration fees. Transaction fees and network transaction acceleration fees are paid in advance by customers, and block rewards are generated by the system.
Retrieval market: The Filecoin retrieval market is an off-chain market, which provides data required for customer retrieval, and retrieval services are provided by the retrieval party. The search party does not participate in the block generation process, and directly obtains the corresponding service fee from the client. The data source of the retrieval party can be from other clients, storage parties or IPFS network.
10. Introduction to the IPFS Ecological Picture
As the network launched in 2015 and completed a huge financing in 2017, the IPFS and Filecoin network will finally enter a new chapter in the launch of the main network this year. In the past few years, the blockchain and digital asset industry has developed a prosperous ecosystem around IPFS and Filecoin.
Have you remembered the above ten knowledge points? Seeing this, I believe that many friends have already felt the power of IPFS and smelled the huge business opportunities hidden in it.
What is an opportunity? When Baidu had Baidu Cloud, Alibaba had Alibaba Cloud, and Tencent had Tencent Cloud, this is the opportunity that technology presents and investors should see.
The current IPFS and its incentive layer Filecoin project broaden your technological vision and realize your wealth and freedom. It is an opportunity in opportunity!
