BSN IPFs (interstellar file system) private network introduction, functions, architecture and characteristics, access instructions

Today, , With information technology 、 The Internet is increasingly developed , The way of human communication and cooperation has undergone disruptive changes . Whether it's numbers , Or words 、 picture 、 music 、 video , Can be obtained from the Internet , You can master all this with a little finger . information technology 、 The Internet has greatly facilitated our production 、 life .

One side , We are enjoying Internet dividends . On the other hand , After decades of development , Once we were proud of the Internet technology has also exposed many drawbacks . When we open a web page , I often meet Caton 、 Data has been tampered with , Even if the file is deleted , Not to mention the problem of data leakage . In addition, the cost is high , Unstable service . Today, more and more attention is paid to the value of data , This problem is particularly serious .

Is there a technology , Low cost 、 Store our data efficiently , Safe and stable 、 Never lose , Of course, privacy protection is essential .

The answer is yes , This is it. IPFS（ Interstellar file system ） technology . Compared with traditional centralized storage technology , Based on decentralization IPFS Technology has low cost 、 high efficiency 、 Security 、 Privacy 、 Permanent and other advantages .

The present , Blockchain is a disruptive and innovative technology , It has great application potential in all walks of life . But due to high storage costs 、TPS Limit , The full data link obviously has no reality and price advantage . Large file hashes are chained , The original document is written in IPFS Storage ,IPFS Technology can be said to be the perfect complement of blockchain .

2021 year 1 month ,BSN IPFS Service private network commercial release , It is BSN be based on IPFS A private network built by distributed file services , For application development IPFS Service gateway of common native service interface . It has high efficiency 、 compliance 、 Obvious price advantage and many other advantages .

that ,IPFS What is it ？IPFS What is the function of ？ How about its architecture and features ？Filecoin What's the matter ？ How to access BSN in IPFS Private network services ？

1. What is? IPFS

understand IPFS, Understand first HTTP.HTTP（ Hypertext transfer protocol HyperText Transfer Protocol,Http） Used in Internet Send and receive messages on . It is designed for hypertext transmission 、 be based on TCP/IP Implementation of application layer protocol .

The data transmitted by this protocol can be in the form of ordinary text 、 Hypertext 、 Audio 、 Video and so on . The user to use http:// or https:// Links to web pages 、 Images 、 The spreadsheet 、 Data sets or tweets , Users identify content by its location , This is location addressing . The link points to web Identifier of a specific location on , It corresponds to web A specific server or server group somewhere on , The person who controls the position controls the content .

Corresponding to location addressing ,IPFS（InterPlanetary File System, Interstellar file system ） It's a content-based addressing 、 Distributed 、 New hypermedia transmission protocol . The principle is to replace the address based on domain name with the address based on content , In other words, what users are looking for is not an address, but a content stored in a certain place , It aims to make the network faster 、 More secure 、 More open .

2.IPFS The function of

Why IPFS？

as everyone knows , The Internet is built on HTTP Agreement on the . But with the progress of the Internet ,HTTP Gradually show its shortcomings .

HTTP Very central , Users rely on a few service providers , Low efficiency and high cost ;W e b Files are often deleted ; Centralized service providers are extremely vulnerable to attack , For the normal operation of the server , Need to adopt all kinds of expensive security solutions , The cost of prevention is getting higher . These three points have become HTTP Insurmountable problems .

contrast HTTP,IPFS Nature is distributed 、 Point to point architecture , No longer rely on backbone and centralized servers .IPFS Divide the file into many small pieces , Stored on many nodes . When downloading , Many nodes can provide download services at the same time , Faster .

second ,IPFS Optimized storage space , Sustainable data preservation .IPFS Store the data by establishing hash and de duplication for the data content . stay IPFS in , The same data will be in IPFS Filtering in the network , This reduces the cost of storage space .IPFS It provides a way for sustainable storage of Internet data , It also provides the function of data historical version tracing .

Third , Based on decentralization IPFS More secure , Born to resist DDOS（ Distributed denial of service attacks ）.

Blockchain and IPFS The relationship between ？

One of the functions of blockchain itself is to reach consensus among participants without centralization , Participants jointly maintain a set of account books . Its efficiency is not high . If IPFS Work together with blockchain , It can make up for the two defects of blockchain .

The first defect is the low storage efficiency of blockchain 、 The high cost . and HTTP similar ,IPFS Is based on TCP/IP Application layer protocol . Encounter large file uplink , You can use I P F S Store the file data itself , And will be the only permanent available I P F S Address is placed in blockchain .

The second defect is that traditionally, cross chain blockchain requires collaboration between various chains , It's hard to reconcile .I P F S adopt I P L D Define different distributed data structures , It can help transfer information and documents between chains .

3.IPFS Architecture and features

IPFS framework

IPFS It includes a seven tier architecture , Each layer has different functions .

IPFS characteristic — Distributed hash table (DHT)

A hash table is a data structure , It is the KEY and VALUE Correspond in some way . Use hash() Function to put a KEY Value maps to a index On , namely hash(KEY) = index. So you can put one KEY Value is the same as a index correspond . Then put it with this KEY Value corresponding VALUE Store in index In the marked storage space . such , Every time I want to find KEY The corresponding VALUE When the value of , Just do it once hash() Operation can be found .

for instance ： Books in the library will be borrowed by someone , such “ Title ” and “ The person's name ” Between the formation of KEY And VALUE The relationship between .

IPFS characteristic — Block switching protocol (BitTorrent)

It is far from enough to realize the distributed storage of data , Data also needs to be effectively exchanged between nodes , So that the whole system can operate efficiently .IPFS Agreement subject to BitTorrent Inspired by the , Data is distributed by exchanging data blocks between peer nodes .

How to encourage nodes to share data ？IPFS stay BitTorrent On the basis of , Added including credit 、 Strategy 、 The system including the bill , The new data exchange protocol based on this system is called BitSwap.

stay BitSwap Under the agreement , Sending data to other nodes can increase the credit value of nodes , Receiving data from other nodes will reduce the credit value of the node . in other words , If a node continues to share data , The probability of other nodes sending data to it will be greater and greater ; If a node only receives data and does not share data , The probability of other nodes sending data to it will be lower and lower , Until it is low enough to be ignored by other nodes .

IPFS characteristic — Self validating file system SFS

Self validating file system （Self-Certifying File System,SFS） It is to design a complete set of file system shared by the Internet , Global SFS All systems are in the same namespace . stay SFS in , Sharing files can be very simple , Just provide the file name . To achieve a globally shared file system , The biggest obstacle is how to make the server provide authentication for the client . One of the simplest ideas , All servers generate a pair of public and private keys , Then let each client use the public key to verify the security of the server , But how to make all clients get the public key of the server ？SFS Use a new solution , Embed the public key information into the file name , This is named “ Self validating file name ”. In this way, there is no need to implement key management inside the file system . The function of secret key management is added to the rules of file naming by users . Users can choose the encryption method according to their own needs .

IPFS The solution is as follows ：

NodeID = hash(node.PubKey)

Assign a variable namespace to each user , In this way : /ipns/

A user can publish an object signed with his private key under this path , such as ：

/ipns/XLF2ipQ4jD3UdeX5xp1KBgeHRhemUtaA8Vm/

When other users get objects , They can detect whether the signature matches the public key and NodeID matching , Verify the authenticity of user published objects , The acquisition of variable state is achieved .

IPFS characteristic -MerkleDAG

Merkle DAG Characteristics ：1、 Content addressing 2、 tamper-proof 3、 duplicate removal .

4.Filecoin： be based on IPFS Public chain of Technology （IPFS Public network ） project

IPFS and Filecoin They are all projects created by the protocol Laboratory ,IPFS And Filecoin The relationship between blockchain and bitcoin is somewhat similar .Filecoin The birth of is to promote through the mechanism of economic incentives IPFS The development of .Filecoin We have adopted the public chain certificate system and issued Token,Token abbreviation FIL, Total number of issues 20 Billion .

Virtual currency is just an application based on blockchain Technology , It does not represent blockchain . Just like using blockchain technology without buying bitcoin , We use IPFS Technology does not need to be purchased FIL, Not to mention compliance issues .
