Introduction

Blockchain Technology has revolutionized various industries by providing a secure and transparent way to record and verify transactions. However one of the challenges faced by traditional blockchains is the centralized storage of data, which can lead to single point of failure and increased vulnerability to censorship. In this blog we will discuss into the integration of Interplanetary with blockchain system, exploring the potential benefits of decentralized file storage and the impact on the future of blockchain technology.

What is IPFS?

The InterPlanetary File System (IPFS) is a protocol, hypermedia and file sharing peer to peer network for storing and sharing data in a distributed file system. IPFS uses content addressing to uniquely identify each file in a global namespace connecting IPFS hosts. Unlike traditional file systems that let you rely on centralized server, IPFS uses a decentralized network of nodes to store and retrieve content. Each piece of content on IPFS is identified by a unique cryptographic hash, making it immutable and resistant to tampering.

IPFS and Blockchain

Blockchain is a decentralized peer-to-peer network that provides immutability and thus, is the best choice to support traceability of data on a distributed file system like IPFS.

IPFS and blockchains share a similar structure and work well together. To understand it well, imagine it like IPFS would connect all different blockchain quite like how the internet connects all websites. It might as well act like a backbone structure for the new web. Like we link one page to another using a link, a link can be placed in Ethereum in order to link to some other network.

Hence, the future of IPFS and blockchain is quite closely related and they might be integrated to generate a consolidated engine of decentralised finance and applications.

Application of IPFS in Blockchain

InterPlanetary File System (IPFS) finds several valuable applications within the realm of blockchain technology, enhancing aspects such as data storage, content distribution, and overall system resilience. Here are some key applications of IPFS in the blockchain space:

1. Decentralized File Storage:

• Use Case: Blockchain networks generate a significant amount of data, including transactions and smart contract details. Storing this data on a decentralized file system like IPFS ensures that it is distributed across a network of nodes rather than relying on a central server.
• Benefits: Improved data integrity, reduced vulnerability to single points of failure, and enhanced censorship resistance.

2. Immutable Content Addressing:

• Use Case: Content addressing in IPFS assigns a unique cryptographic hash to each piece of content. Blockchain projects can use this feature to create tamper-resistant references to documents, ensuring that the content remains immutable over time.
• Benefits: Enhanced security, tamper resistance, and the ability to verify the integrity of stored content.

3. Decentralized Applications (DApps):

• Use Case: DApps often require storage for various assets, such as images, videos, and other media. IPFS can be integrated into DApps to provide a decentralized and distributed storage solution for these assets.
• Benefits: Increased resilience, improved scalability, and reduced dependence on centralized servers.

4. Interoperability Between Blockchains:

• Use Case: Different blockchain networks can utilize IPFS as a common protocol for decentralized file storage, fostering interoperability. This enables the seamless sharing and retrieval of data between disparate blockchain ecosystems.
• Benefits: Facilitates collaboration between blockchain projects, promotes data sharing, and supports a more interconnected blockchain landscape.

5. Content Distribution Networks (CDNs):

• Use Case: IPFS can be employed as a decentralized CDN for distributing content, such as media files, across a network of nodes. This is particularly useful for blockchain-based projects that require efficient and decentralized content delivery.
• Benefits: Improved speed, reduced latency, and a more efficient distribution of content across the network.

6. Immutable Timestamping:

• Use Case: IPFS can be utilized to create immutable timestamps for documents and data stored on the blockchain. This timestamping ensures a transparent and verifiable record of when specific information was added to the IPFS network.
• Benefits: Enhanced transparency, traceability, and auditability of data changes over time.

7. Supply Chain Management:

• Use Case: Integrating IPFS into blockchain-based supply chain solutions ensures that relevant documents, certifications, and transaction details are securely stored and easily retrievable in a decentralized manner.
• Benefits: Improved transparency, traceability, and resistance to data manipulation within the supply chain.

8. Peer-to-Peer Transactions:

• Use Case: IPFS can facilitate peer-to-peer transactions by allowing users to exchange files directly without relying on a centralized intermediary. This is particularly relevant in scenarios where parties need to share large datasets securely.
• Benefits: Direct and secure file exchange, reduced dependence on centralized servers.

In summary, the integration of IPFS in blockchain systems enhances data storage, content distribution, and overall system robustness, contributing to the development of more resilient and decentralized applications across various industries.

How does The IPFS work

In the decentralized web powered by IPFS, all connected computers, called nodes, form a network where data is stored and shared. Nodes can store information and make it available to anyone who asks for it.

When someone requests a file or webpage, a copy of that file gets saved on their own node. As more people request the same data, more copies are created and stored across various nodes. Future requests for the same file can be handled by any node, or a combination of nodes, that already has a copy of the file. This way, the responsibility of delivering the data is spread out among many nodes.

This decentralized approach requires a new kind of web address. Instead of using an address that points directly to the location of the data (like a specific URL), the decentralized web relies on content-based routing. In simple terms, you don’t need to know where the data is stored; you just request what you want, and the system finds and brings it to you. Because the data is distributed across different computers, they can all contribute pieces of the data to your computer simultaneously, similar to how files are downloaded in a torrent. This method aims to make the process faster, use less internet bandwidth, and avoid potential issues caused by relying on a single central server.

IPFS is a Content Based Addressing

IPFS Object
A Link structure has three data fields:

• Name — the name of the Link.
• Hash— the hash of the linked IPFS object.
• Size — the cumulative size of the linked IPFS object

IPFS objects are normally referred to by their Base58 encoded hash.

Exemple: IPFS object with hash
f1bf8e4c64f4ec2fb3a1fa3aa08f96bf1bca25532c128644c5a96768cf0bee05

As we can see in the above image, photo will be converted into a binary file, then using IPFS technology this binary file will be split into different chunks.
Each chunk has its own Hash called CID(Content Identifier).
USE CASES

The use of IPFS has improved the current technology sector, and many companies are using it in their use cases. Netflix, Opera or Chrome are some company that rely on this technology. It is not only because data is stored in distributed manner but It also optimizes and improve the operation of processes on internet.

• End of “servers” hosting websites. All content will be delivered from IPFS and data will be pulled directly from the blockchain.
• End of web registrations to obtain accounts. Your private key will grant permission and access to your identity to websites / providers.
• Direct communication with other people without intermediaries. Truly secure, private and uncensored communication applications.
• Social networks where your information is only available to those to whom you give permission.

Within these use cases, we can highlight several companies that are implementing them effectively:

• Cloudflare, runs a distributed web gateway to speed up and secure access to IPFS without the need for a local node.
• Microsoft ION, The digital identity system is built on Bitcoin and IPFS and its objective is to build a technology that allows creating a secure and scalable digital identity system at a global level.
• Brave, the search engine uses Origin Protocol and IPFS to host its decentralized merchandise store.
• Opera para Android has default support for IPFS, allowing mobile users to navigate ipfs: // links to access data on the IPFS network.
• Wikipedia uso IPFS They have developed a mirror of their website, which allows them to access Wikipedia from jurisdictions where it is censored.

Conclusion

IPFS plays a vital role in enhancing the capabilities of blockchain systems by providing decentralized and efficient file storage. Its content addressing mechanism aligns well with the principles of blockchain, fostering immutability, decentralization, and efficient data retrieval. As the technology continues to evolve, the synergy between IPFS and blockchain is likely to drive innovative solutions in various domains.
