NFT "non-homogeneous pass"The nature of NFT determines the uniqueness of NFT.People's pursuit of "uniqueness", "differentiation", and "uniqueness" has accelerated the arrival of the NFT boom.The vulnerability of NFT storage infrastructure has long foreshadowed that NFT andFilecoinThe inevitability of union and the broadness of prospects.Why are NFTs different?
Perhaps, many people have doubts, what exactly is NFT? Why is NFT "non-homogeneous"?
All of this has to start with the source of NFT.At present, most of the tokens we have seen, such as stable coins such as USDT and DAI, and DeFi tokens such as LEND, YFI, SNX, and UNI, are all created and issued on the ERC-20 of Ethereum.The tokens created on Ethereum's ERC-20 are all homogeneous. For example, based on ERC-20 USDT, the 12 USDT in your hand is the same as the 12 USDT in my hand.NFTs are different
The bottom layer of NFT is based on Ethereum ERC-721 and ERC-1155. The tokens created based on ERC-721 and ERC-1155 have their own characteristics and value, and cannot be unified.ERC-721 is a common standard for creating NFTs. ERC-721 allows the creation of contracts with distinguishable tokens with different properties. A common example is "CryptoKitties", which is a game that allows the collection and breeding of virtual kittens, but each CryptoKitties has a different color, a different breed, and a different generation, so the price of each cat is also different.ERC-1155 is used in the next step of creating NFT. The ERC-1155 standard allows developers to freely define homogeneous and non-homogeneous tokens and specify the quantity. For example, in many games such as "World of Warcraft", players can hold non-homogeneous items (such as swords, shields, armor) and homogeneous items (such as gold or arrows) at the same time. They are the same, but the defense and attack capabilities of non-homogeneous items are different.Three major problems with NFT
NFT is part of the blockchain and powered by blockchain technology, but it does not mean that NFT is perfect. In fact, many NFTs are vulnerable to damage and even manipulation."Non-genuine" risk: The artist's work is sold without his consent. According to the artist Derek Laufman, someone sold his artwork in the form of NFT on Rarible by forging his personal information. Generally speaking, in order to ensure the authenticity of artworks, people need to verify the NFT smart contract on the blockchain browser Etherscan, however, there are many NFT projects that have not completed this necessary verification, which means that there may be related Counterfeit Products.
Traditional storage "ownership" disputes: The reason why NFT can be sought after is that NFT represents ownership. However, most NFT projects use traditional centralized storage methods, which means that these NFTs are open to storage service providers and can be changed at will, which means that under the background of centralized storage, The NFT project itself is fragile, and even according to Twitter users, the NFT project has problems such as rug-pull.
The "permanence of time" of traditional storage cannot be guaranteed: We all know that traditional centralized storage cannot guarantee the permanence and sustainability of the website. On average, the lifespan of the website is between 2 and 5 years, and NFT is stored in On the traditional cloud storage network, if the company that owns the server goes bankrupt, the NFT will also disappear.
When people buy NFT, what they buy is the real ownership of NFT. Only true ownership can have scarcity and uniqueness, and can satisfy people's psychological pleasure and pride after purchasing. Therefore, most people do not pay for the artwork itself, but for its "uniqueness".
How does Filecoin help NFTs?
First of all, we need to understand that it is not that NFT projects stubbornly want to store data in traditional data centers, but because there is a certain limit to the size of data directly stored on the blockchain. For example, the data stored in Bitcoin, which has been issued for ten years, is a drop in the bucket compared to Filecoin.However, IPFS is a hypermedia transmission protocol based on content addressing, versioning, and point-to-point. It is a P2P distributed file system. the Internet.Filecoin is the only incentive layer of the IPFS network. In less than half a year and less than a year since the mainnet was launched, the Filecoin network has stored nearly 5EiB of data.Compared with HTTP, IPFS and Filecoin focus more on speed and security, and can be used to store NFT assets.Filecoin realizes distributed data storage for buyers and creators, while IPFS replaces traditional https:// address addressing with content, and content is confirmed by encrypted hash instead of address. IPFS even helps creators mint and store NFTs with a simple command-line application of Minty.Therefore, in theory, Filecoin and IPFS can lead the safe storage of NFT.In fact, Filecoin launched a free NFT distributed storage solution to help NFT become better with practical actions.According to the official Filecoin blog, Filecoin has launched a free NFT distributed storage solution - NFT.Storage.NFT.Storage, a service created by Protocol Labs and Pinata for NFT data storage, enables developers to utilize content and decentralized storage to protect NFT assets and related metadata, and ensure that all NFTs follow best practices and can long visit.To put it simply, NFT.storage utilizes the elasticity and persistence of IPFS and protocol currencies to allow developers to store NFT data on a distributed network, and the conversion process becomes simple, safe and free! With just a few lines of code, anyone can maintain persistent storage of NFTs via IPFS and Filecoin.In general, Filecoin can provide a persistent protocol layer through cryptographic proofs to ensure the persistence and durability of NFT data. Currently based on Filecoin, NFT can realize long-term distributed data storage, connect storage transactions and retrieval transactions, and preserve the security, accessibility and uniqueness of NFT data for a long time.The combination of the two fields of NFT and Filecoin is expected to jointly accelerate the implementation of the blockchain and a new round of explosion!
