Permanence and invariance are essential parts of the irreplaceable and unique NFT industry. Market capitalization is projected to reach $710 Million by 2021. The non-fungible token market (NFT) is experiencing steady growth. These fundamental flaws in design make it impossible to provide these characteristics for NFTS that are targeted at consumers. Additionally, the increasing number of assets are minted with NFTs at-risk.
NFTs were intended to remain on the blockchain for a lifetime. Due to limited space and cost, NFTs are only stored as an ownership record. However, metadata linking original NFT content is also kept. These links can be fragile and direct users to a particular location (using HTTP protocol), instead of an asset. This implies that the linked content is susceptible to being changed or removed at any time (due to broken links, rug pulls and 404 errors) which can lead to permanent loss of original assets.
Blockchain is an excellent tool for managing minting, bookkeeping and immutable metadata across many nodes. It is also very expensive to replicate large amounts of data using blockchain. This makes it difficult to store data on the platform. This is why the launch of IPFS, or Interplanetary File System (Interplanetary File System), was necessary to store and secure off-chain NFT information.
IPFS is an IPFS that can address these issues and provide NFT data storage in a permanent and accessible manner on a decentralized network. It acts as a peer-to–peer version-controlled data system and hypermedia protocol to store, retrieve and manage the data. IPFS can identify every file in a global NFTs namespace to allow NFTs link the NFT metadata of the digital asset with its content addressing feature. IPFS is more persistent than other centralized services, such as Dropbox and Google Drive.
What is IPFS, and how can it store NFT information?
IPFS, an open-source hypermedia protocol, allows peer-to–peer (p2p), decentralized data storage through:
- Simple sharing
- Censorship Resistance
- It is easy to retrieve
IPFS makes it possible to move data throughout the network and locate what you need using its content address and advanced file versioning data structures.
These three basic steps, which are built upon each other, make up an IPFS ecosystem.
Step 1: Content Addressing via unique identification
When users upload NFT information to IPFS they get an IPFS hash, also known as aCID. CIDs can be described as unique identifiers, or addresses, of NFT data used to refer the content regardless of its location. CIDs are generated from the content. CIDs are used to refer NFT data and prevent issues such as fragile links or rug pulls.
IPFS follows certain data-structure preferences, conventions and IPLD. This IPFS address uniquely identifies content within the IPFS network. The next step is to examine how links between content can be embedded within that content address via a DAG information structure.
Step 2: Content Storage and Linking via DAGs
IPFS offers decentralized data storage options and retrieval methods to keep NFT data long-term. IPFS’s permanence layer is cryptographic and ensures long-term persistence and durability of NFT information.
IPFS uses a Merkle DAG for NFT data link. It is optimized to represent files and directories. You can structure a Merkle DAG many different ways.
IPFS first splits the file into blocks to create a Merkle DAG representation from your NFT data. The ability to split it into blocks allows for different parts of the file to be authenticated quickly and can come from different sources. Merkle DAGs provide another important feature. When you have similar files, Merkle DAGs from different sources can be used to reference the same data subset.
It makes it easier to transfer multiple versions of large datasets (such a genomics research data or weather data). This is because you can only transfer the new parts and not create completely new files each time. Merkle DAG is used to link all NFT data.
Step 3: Content retrieval via Distributed hash tables
IPFS uses a distributed haveh table to identify peers that host NFT data. A hashtable is a database of keys and values. This hashtable is distributed among peers within a distributed network. The libp2p manages connectivity and interactivity among peers.
The libp2p querying the DHT allows you to determine which peers hold each block that makes up the NFT Data. Once you’ve found the content, you will need to connect to it (NFT Data) and retrieve it.
IPFS uses Bitswap for this purpose. It establishes connections with peers to send a wish list (a list containing all blocks containing NFT data) and sends them a connection. After receiving the requested content blocks, you can verify their authenticity by hashing them and comparing their CIDs. These CIDs can also be used to deduplicate blocks.
How does Libp2p support multiplexing?
It’s not easy to establish a connection and manage its expenses. Libp2p enables multiplexing between peers with high interoperability. It also eliminates the need to establish multiple connections for different services. The DHT that libp2p provides is used to retrieve the content. After this, the user can then download it through a multiplexed link. The stack’s middle is what holds it all together, and links them with unique identifiers.
