Ipfs is a global, P2P point-multipoint distributed storage protocol, which can connect all the same file system, the traditional Internet protocol HTTP is mainly searching for domain addresses, while ipfs is searching for content addresses, the emergence of ipfs beyond the http protocol, the future of the Internet may be ipfs trend.
About storage:
Storage is actually the storage of data, the development of the Internet is very rapid, the arrival of the 5G era, nothing more than to bring more tests, 5G technology, big data, the arrival of artificial intelligence and the Internet of Things, their operation, when it comes to the data, the accumulation of historical data and real-time data to show a huge amount of data, the storage of these data has become a big problem. The original storage can no longer meet the needs of the current data, these data need to be stored and circulated. So, like Ali cloud began to develop data cloud 10 years ago, because Ma Yun saw the future of the magnitude of data storage, the magnitude of this data will continue to grow with the further growth of the technology, some of the world's current well-known data cloud such as Amazon cloud, Ali cloud, Huawei cloud, Tencent cloud, etc. can not meet the world's growing demand. So the world, need bigger and better more secure storage cloud.
Storage is divided into DAS (direct storage), centralized storage, distributed storage three.
DAS: It is mainly storage and computing connection with scalability and less flexibility. Centralized storage: it is rich in device types, mainly through the external P/FC network interconnection, with scalability; by the controller capacity constraints, limited scalability, belonging to the petabyte level; equipment to the life cycle when the need to replace, in the data migration time-consuming need to consume energy. Distributed storage: distributed storage is mainly used on a large scale in the Internet, it pursues scalability and low cost, after entering the traditional enterprise market, began to build the enterprise-class storage capacity, distributed storage is scalable, relatively easy to operate and maintain, on-line fast.
Distributed storage refers to a unique type of system framework, which consists of a group of computer nodes that communicate through the Internet and coordinate their work in order to accomplish the same task as the ****, which exists to solve the problem of inexpensive, ordinary machines to complete the computation and storage problems that individual computers are unable to complete. It is mainly to utilize more machines to complete more data calculation and storage. Simply put, it is like a car pulling goods, for example, the car is a machine, the goods are data, before a car transportation of goods is limited in number, the need to change the larger trucks, and now you want to pull more goods can be used directly with the train, pulling more goods will be added directly to the carriages, each carriages have the power to do, so there is no need to worry about pulling the goods. Distributed storage principle is the same as this. Storage after decades of development, derived from a variety of storage products to meet a variety of different needs of enterprise applications. In this era of digitalization, the core of storage must be customer-oriented, data-centric, and advocate the concept of data-on-demand services.
ipfs "distributed storage" has two very important two cornerstones: storage and distributed. ipfs distributed storage features are mainly permanent, decentralized preservation and *** enjoy the file (blockchain mode of storage). Peer-to-peer distributed: P2P peer-to-peer storage of a wide variety of different data. Versioning: Files can be traced back to their modification history. Content Addressing: Generating a separate hash value to identify a file by its content, rather than by the location where the file is stored. For example, if we are looking for a person, in the era when there were no telephones, we would look for the person by their location, and would need to look for all the possible places that the person could be. And now, we are through the content to find the location of the way, just search for the name of this person can find this person, saving time and through the location of the search is to meet the malicious information, encountered a dangerous and lead to their own information, network, money and so on are threatened. It will be the same content of the file in the system backup unique, saving the system storage space (blockchain mode). ipfs distributed storage simply means that the data is decentralized storage to multiple data storage servers.
About Filecion miners:
I believe that many people nowadays are no strangers to virtual currencies, and many people are playing with bitcoin, which is a kind of virtual currency, and these virtual currencies need to be mined with a miner to obtain them. The way of mining has graphics card mining, CPU mining, etc. Knowing the way of mining, the principle of mining, in order to better mine the virtual currency. So what does Filecoin mining mean?
In order to protect the implementation of the IPFS project, there is to prevent all IPFS nodes will not be because the operator maliciously carry out data deletion or shut down the node, resulting in the storage user can not get the data digital display of the shortcomings. Therefore, the emergence of Filecoin, Filecoin using the reward and punishment mechanism, through the protection of the normal operation of the node to obtain Filecoin rewards, if there is a malicious deletion of data and shut down the node Filecoin. the emergence of Filecoin to protect the normal operation of the IPFS network, to maintain the order of the network, those who violated the IPFS network normal will be Those who violate the normal IPFS network will be fined and confiscated all the Filecoin rewards. In general, under normal circumstances, this situation will not occur, through the normal operation of the node can be obtained Filecoin rewards, as long as there is a corresponding reward, almost all people will comply with the network order.
In the early days of Filecoin, just like Bitcoin, everyone is actively participating in Filecoin miners, hoping to become a member of the link in the earliest days, everyone's idea is the same, thinking that the sooner you enter, the more you dig, the more you make, like the early drop drivers, everyone has earned, because there are a lot of incentives, and Filecoin also has a lot of reward policy. So, IPFS hard disk miner is not yet much popular in the market, and it is critical to choose a good miner early on.
