What is IPFS InterPlanetary File System? » Moralis » The Web3 Development Workflow

The gateway transmits the specified file once that content has been located. This indicates that the updated copy of the file gets saved alongside the old one. IPFS works as a distributed file system, and the principle of updating ensures that the file system remains immutable. Rather than using address-based routing, which requires you to identify where the data is stored and offer a precise URL for it. Web3 has been rapidly scaling over the past 18 months, integrating with a wide range of browsers, projects and ecosystems, with the declared tenets of privacy, anti-censorship, decentralization and ownership. IPFS is not as smooth and easy to use as standard websites, but like a lot of Web3 platforms right now, that should improve over time—particularly as native link support comes to more web browsers. There’s also a service called Unstoppable Domains that provides easier-to-remember URLs to point to IPFS content, and more browsers are starting to support those as well. As of August 2021, IPFS claims to have 2 million unique weekly users, some 200,000 network nodes, and about 125TB worth of gateway traffic per week. As a good example, if your NFT on the blockchain points to a normal link, that link can break, vanish and stop working or serve an entirely different content in the future.

Are IPFS files permanent?

Filecoin, or IPFS on the blockchain

This is probably more robust than a random web server run by some random software project hosted in AWS, but it is by no means permanent. Lots of blockchains have gone defunct in the past, and there is no reason to think that Filecoin is an exception.

DApps can range from digital asset exchanges, games, and social media platforms. Now that we have established how the data is structured and linked together using IPFS, we must also discover how the system can locate data. To find data within the network, IPFS utilizes something called Distributed Hash Tables or DHTs. A hash table is a structure that maps keys to different values, but the hash tables in IPFS are distributed; what does this mean? The fact that the hash table is distributed means that it is split across all the nodes in the network. Then to locate the content you are after, you ask the peers in the system. We have established a basic understanding of “what is IPFS”, as well as what content-based addressing is and how it functions. However, the description above still leaves some questions unanswered, such as how the system stores files in the data structures. To bridge the gap between hash-linked data structures, IPFS includes something they call InterPlanetary Linked Data projects. IPLD translates the hash-linked data between different distributed systems to enable synergies.

These networks are democratized through the use of consensus mechanisms. The AXEL network uses Masternodes to perform transactions and achieve consensus. Since these Masternodes are owned and operated independently, the network’s power and control are governed by the network, not by an individual or a corporation. IPFS is the perfect complement to a decentralized network as it is an open-source file storage and management operating system designed to enable interoperability across networks and domains. By combining these two powerful technologies, true decentralization of network resources and control can begin to grow. That means, if Wikipedia utilized IPFS to store its content, it would be stored across a distributed network instead of a central server. And as long as at least one of the nodes storing a particular page is online, users will be able to access that page by entering the link to it. The web as we know it today is controlled by centralized servers and accessed by location-based addressing. With that comes potential issues in the chance that a server is hacked, or if it happens to crash.

What is the difference between IPFS and blockchain?

While blockchain shares a ledger with its nodes, IPFS is a peer to peer file-sharing system that hashes files (similar to the way blockchain hashes transactions), and then allows users to search for files based on those hashes.

The “Explore” icon opens a screen that lets you browse through different types of information stored within IPFS and its Merkle forest. To change to a different screen, click one of the icons in the left-hand sidebar. The “Files” screen lets you see the files you’ve imported into IPFS. You can use the blue “Import” button to search for files or folders on your computer that you want to import into IPFS. Of course, all of this depends on a sufficient number of nodes being on and available, and with enough pinned and cached data. The IPStorm botnet, first detected in June 2019, uses IPFS so it can hide its command-and-control amongst the flow of legitimate data on the IPFS network. Security researchers had worked out previously the theoretical possibility of using IPFS as a botnet command-and-control system. Please consider expanding the lead to provide an accessible overview of all important aspects of the article. To export or read the file data out of the UnixFS graph, perform an in-order traversal, emitting the data contained in each of the leaves. Rabin chunking will chunk the input data using Rabin fingerprinting to determine the boundaries between chunks.

IPFS is becoming an industry standard in blockchain projects because of its flexibility and security. With the rise of non-fungible tokens , IPFS has become an important tool for NFT marketplaces to store information about the works they publish. At the beginning of the article you learned that content added to your node via the ipfs add command or its HTTP equivalent is pinned by default. To replicate content, you must take your node online, join the p2p network, and pin the specific CID from another node. You will learn how to do this further in the tutorial and find out what happens in the background. By default, it will create a folder and store all the data in ~/.ipfs You can tweak this by configuring the IPFS_PATH ENV variable. When you think about developing a decentralized application, a blockchain like Ethereum probably comes to mind. It is an ambitious plan to make the internet more free, open, secure, and high-performance.

An alternative solution to solving these problems with the internet is the InterPlanetary File System . The IPFS is a decentralized file-sharing/storing system that functions through a P2P network. In this system, files are not stored on servers but are held by the system’s nodes and shared between them. To enable this, the system uses content-based addressing, which means that files are located based on content and not location as on the internet today. In IPFS, content is not housed in a single location but in several locations in a shared network using a distributed hash table . A user requests content based on its unique CID, IPFS retrieves that data from multiple nodes at once, and it is then delivered to the user in the most efficient way possible. This decentralized system allows bandwidth savings and improves data resilience, security, integrity, and performance. IPFS allows users to host and receive content in a manner similar to BitTorrent.


When the user accesses or downloads the file, their IPFS node caches a copy of the file, becoming another peer that can pass content forward. As with other forms of caching, content can be cleared over time (and can conversely be “pinned”) to preserve a node’s storage space. By design, IPFS is far more robust from a security standpoint than centralized storage. Every year, we see more and more news stories about massive data breaches affecting millions of lives. The problem lies in the fact that these massive data repositories are centralized. This makes them easier for hacker targets because they know all the data is stored in the same repository. So you can attack a large storage target and get massive amounts of information for your efforts. IPFS is specifically designed to support decentralized and distributed storage.

You can put IPFS CID into an NFT so that it references the data itself rather than a traditional HTTP link, which is likely to fail over time. This means as long as one copy of the CID exists on the IPFS network, it can be accessed. A self-certifying file system is a distributed file system that doesn’t need special permissions to exchange data. The data served to a user is simply authenticated by the file name, which is signed by the server. Meaning, you can securely access remote content with transparency of local storage. Maintains the quality of older web pages — Have you ever asked what happens to your websites once you pass away? If your website is dependent on centralized social networks, it may succumb to ‘link rot’ and vanish forever, taking your collections with it.

Running an IPFS node

You can read more about its origins in the paper IPFS – Content Addressed, Versioned, P2P File System. ”, we’ve found that IPFS is a distributed system for accessing and storing files. What’s more, IPFS uses a content-based addressing system, along with a long list of innovative technologies, including InterPlanetary Linked Data and Merkle Directed Acyclic Graphs. Since Internet content is stored in centralized servers, companies controlling those servers can also control the speed at which content is delivered. Nevertheless, storing all information in central servers can cause problems, like censorship and having a single point of failure. The internet is an amazing invention that has become intertwined in billions of people’s everyday lives. Everything between banking, learning, watching movies, and connecting people are done using the internet. It’s impossible to deny how the internet has become one of the most important inventions for society, but yet, it isn’t entirely perfect. Specifically, one of the problems with the current state of the internet is that it is centralized.

The “Explorer” icon opens a screen that allows you to browse different types of information stored in IPFS and its Merkle forest. Of course, this all depends on having enough nodes enabled and available, and with enough pinned and cached data. It allows us to serve user uploaded files within districts and to serve up our website source code displaying the corresponding web page. The distributed web will quickly become the fastest, most available and largest store of data on planet earth. And no one will have the ability to destroy information by shutting it down. Elon Musk’s SpaceX plans to launch a Dogecoin satellite into space this year. Geometric Energy Corporation, a partner to the mission, issued four tokens that let holders change the location, luminosity, color, and duration of advertisements displayed from the satellite. Skiff looks and behaves like any other productivity service you may be familiar with, like Google Docs. You can create new documents, edit them together with your colleagues, and generally use it just like you would any other docs program.

This is intended to lower latency, reduce bandwidth, and avoid bottlenecks caused by a single, central, server. This is a simplification of course, but it does describe the general model. To allow for scaling and to provide robustness, organizations can bring mirror servers and content delivery networks into play. But even then, there’s still a relatively small and finite number of locations that people can go to in order to access those files. The raw leaves format on IPFS where nodes output from chunking will be raw data from the file with a CID codec of ‘raw’. This is mainly configured for backward compatibility with formats that used a UnixFS Data object. This format is the default for CIDv1 created with ipfs add –cid-version 1, soon to become the global default. Why do we say “content” instead of “files” or “web pages” here? Because a content identifier can point to many different types of data, such as a single small file, a piece of a larger file, or metadata.

  • You can pay for storage on cloud storage providers that expose your data to the IPFS network and keep it permanently pinned, and there are services specifically designed to host IPFS-accessible websites.
  • That’s where your data would live locally, referenced by content addresses .
  • When the spaceship gets shot into Earth’s orbit, IPFS could use the node as a relay to further decentralize its network, which hosts things like non-custodial domain names and censorship-resistant websites.
  • Having to access your data on a server from the other part of the world might bring some time complexity to the table.

• Shields your privacy — Because IPFS isn’t reliant on central servers like HTTP, it makes it harder for authorities to prohibit websites like Wikipedia. Naturally, all of this is contingent on an adequate quantity of nodes being up and accessible, as well as adequate pinned and cached data. Whenever anyone asks for a file or a website, their node caches a copy of the file. As more users seek that data, there will be more cached copies available.

The InterPlanetary File System is a peer-to-peer distributed file system that provides data resilience, security, integrity, and performance by enabling content-addressed storage. In this file system, data is addressed based on content instead of location using a distributed hash table , similar to the way blockchain logs transactions. That means instead of retrieving data based on the device it resides on, it is instead assigned a unique content identifier , which provides a permanent record of that file. The InterPlanetary File System is a peer-to-peer distributed file system that provides data resilience, integrity, performance and security through enabling content-addressed storage. Within this file system, data is addressed based on content rather than location utilising a distributed hash table , in a way similar to how the blockchain logs transactions. This means that rather than retrieving data based on the device it resides on, it is given a unique content identifier , which delivers a permanent record of that file.
Companies and individuals are becoming far savvier regarding the privacy and security of their files and personal data. So they seek out more private and secure networks to facilitate the management of their data. IPFS fosters both interoperability and enhanced privacy and security. These links can be shortened to simpler names using a Domain Name System , but this introduces an external point-of-failure for content distribution.
The server is at the center, serving all the requests for access to the data that it holds. During the block of Wikipedia in Turkey, IPFS was used to create a mirror of Wikipedia, which allowed access to the content of Wikipedia despite the ban. However, that version of Wikipedia was archived and therefore static. The balanced layout creates a balanced tree of width max-width.

It’s a decentralized, peer-to-peer file-sharing network and open-source Web3 service designed to overcome centralized points of failure and censorship efforts, to ensure that the web is freely accessible to all. Larger files are split into as many IPFS objects as needed to accommodate the file. One IPFS object per file contains links to all other IPFS objects that make up that file. In the place of based on address routing where you need to know the location of the data and provide a specific URL to that data, decentralized web uses content based routing. Although global, the World Wide Web remains a centralized network. Data storage behind the internet is mostly made up of servers, physical or virtual, in massive server farms or cloud platforms. Servers are owned or leased by other companies and configured and exposed to be accessible to the outside world.
But this is not the case since the IPFS has a solution for this. To find which node/nodes that are hosting a file, the system uses what is known as a Distributed Hash Table . The table tells the users of the network which node has what data. This means that the DHT is used when trying to locate a file through the content-based addressing system.

It is “self-certifying” because data served to a client is authenticated by the file name . You can securely access remote content with the transparency of local storage. Some of the limitations are related to the low incentives to participate in the network, which leads to a small population of peers. The limited adoption makes it harder for files to be permanently available. If certain data is only hosted by a handful of nodes and all go offline, it will become inaccessible.
ipfs file system
IPFS has a peer-to-peer nature which allows users to access data independent of their connectivity or latency issues. If someone requests a file or web page, a copy of the file is cached on their node. As more and more people request this data, more and more cached copies will exist. Subsequent requests for this file can be satisfied by any node the file is on. The load of providing the data and responding to the request is gradually distributed among many nodes.

This verification is done by organizing data blocks using cryptographic hash functions. This is simply a function that takes an input and calculates a unique alphanumeric string corresponding with that input. It is easy to check that an input will result in a given hash, but incredibly difficult to guess the input from a hash. Put simply, the Inter-Planetary File System is a distributed file storage protocol allowing a network of computers to store any arbitrary information in a robust and immutable way. Each computer on the network acts as a client and a server, allowing it to route and cache network requests for other clients. IPFS is a distributed file system that seeks to connect all computing devices with the same system of files. In some ways, this is similar to the original aims of the Web, but IPFS is actually more similar to a single BitTorrent swarm exchanging Git objects.

For example, you can store all Ethereum blocks on IPFS as long as you set eth-block and eth-tx codecs and register an appropriate Decoder when working with the IPLD graph. You can follow this tutorial to learn blockchain by building one from scratch yourself if you want to learn more. The IPFS project is big (and expanding every day!), so we’ve excerpted some frequently-used links and other resources below. However, we encourage you to explore both the main IPFS GitHub org (for core implementations and other mission-critical work) and the IPFS Shipyard GitHub org, home to incubated projects by the IPFS community. If you find a vulnerability that may affect live deployments — for example, by exposing a remote execution exploit — please send your report privately to Please do not file a public issue. The IPFS project seeks to evolve the infrastructure of the Internet and the Web, with many things we’ve learned from successful systems, like Git, BitTorrent, Kademlia, Bitcoin, and many, many more. This is the sort of thing that would have come out of ARPA/DARPA, IETF, or Bell Labs in another age. IPFS is a free, open-source project with thousands of contributors.
