Ordinals NFT, BRC20 craze is rising. In March 2023, a developer named Domodata first proposed the theory of the BRC20 standard. He proposed a standard for creating non-fungible tokens on the Bitcoin blockchain using the Ordinals protocol. Currently, BRC20 has been used to mint more than 10,000 different coins, most of which are MEME Coin. Strong narratives, community-driven and creative marketing are all considered as reasons for the spread of this craze, and NFT has once again ignited the market's enthusiasm.
According to the latest data from NFTScan, as of the end of May, more than 2 million NFT projects have been deployed on mainstream blockchain networks, 810 million NFT assets have been minted , and 2 billion on-chain records have been generated . Currently, there are 110 million The wallet address holds NFT assets.
But looking back at the development history of NFT, secure storage is still an issue that needs to be solved urgently . NFT security incidents occur frequently. Last year, Jay Chou published an article claiming that NFT worth 3 million yuan was stolen. Free Mint scams occurred frequently. BAYC’s official account was hacked...
Many project parties and NFT users can’t help but ask, how to store and hold NFT safely?
How NFTs are stored
NFT storage can be divided into on-chain and off-chain. On-chain storage means that the entire NFT, including the image and all metadata, exists on the blockchain. Off-chain storage means that the NFT content itself is not uploaded to the chain, only the NFT metadata is uploaded to the chain.
On-chain storage allows users to verify all aspects of an NFT, but few NFT projects choose this storage method because JPEG images contain large amounts of data in large NFT collections. Therefore, most NFT projects choose to store the actual images off-chain. Many well-known NFT projects such as CryptoPunks and Bored Ape Yacht Club choose off-chain storage.
Choose a decentralized storage solution
In the case of off-chain storage, the NFT's smart contract contains information pointing to some off-chain location where the actual NFT JPEG image is stored. Typically, NFT images and their metadata are stored in hashes. This hash is used to point to a centralized or decentralized storage service provider.
Examples of centralized storage services include Amazon and Google. The risk of centralized storage services is the risk of the server experiencing failure or being shut down for some reason, resulting in the owner's NFT being lost. In some cases, all the owner is left with is a simple hash that exists in the smart contract. This also explains why many projects choose to use decentralized solutions to store their NFTs.
Why is NFT safer when choosing CESS?
As the first blockchain network to support large-scale commercial storage, Cumulus Encrypted Storage System (CESS) is also a secure, efficient, open source, and scalable decentralized storage network. CESS provides the best solution for the storage and retrieval of high-frequency dynamic data in Web3. Its technical advantages provide more advanced and secure storage services for traditional static NFT and dynamic NFT (dNFT) , and has the following outstanding advantages:
Decentralized, censorship-resistant
Since CESS adopts a decentralized storage method , no single entity has the authority to shut it down, so it is impossible to review and interfere with the storage and transmission of NFT.
Distributed storage to avoid single points of failure
CESS decentralized cloud storage protects NFT storage from single points of failure due to its natural distributed architecture . Even if a node fails, other nodes can still provide NFT access services to ensure the security and availability of NFT.
Efficient, flexible and as good as centralized storage
CESS introduces a decentralized CDN layer to provide scientific and effective incentives for caching miners and retrieval miners to achieve millisecond-level data retrieval and return. While providing efficient NFT access speeds, users can quickly browse, retrieve and trade NFTs.
Copyright protection, creator friendly
A series of NFT tool projects to be deployed based on the CESS network will allow creators to mint, produce and store NFTs without users having to build and maintain servers by themselves. The multi-type data confirmation mechanism (MDRC) innovatively used by CESS allows users to truly control NFT ownership through data traceability, data maps and data similarity algorithms.
CESS provides a practical paradigm for NFT decentralized storage
CESS is currently in the testnet v0.5.3 version. The launch of the DeShare product and the decentralized streaming media platform VIDEOWN within the ecosystem allow us to see the practical paradigm of NFT decentralized storage.
Taking DeShare as an example, users use DeShare to upload data and store the data on the CESS network. There are several key operations:
File Hash is used for content addressing. After the user uses DeShare to upload any file format (image, video, audio, and text), a URL is generated. The link contains the File Hash of the data . A File Hash is a unique fingerprint of your data, a universal address that can be used to reference content regardless of how or where it is stored. Because File Hash is generated from the content itself, using File Hash to retrieve NFT data can prevent problems such as fragile links.
Flexible search. Data stored through DeShare can be retrieved and queried using File Hash in the CESS test network blockchain browser, and can also be obtained in the browser through any public CESS-Gateway.
Provable, recoverable storage. DeShare uses the CESS network for decentralized data storage and supports the storage and retrieval of NFT data. The multi-copy proof-of-recoverable storage (PoDR²) innovatively introduced by CESS generates three data copies by default and supports the recovery of damaged/lost data segments, thereby ensuring the security and integrity of the data and improving the network's disaster recovery capabilities. .
Copy proof confirms the preservation of independent backups, and space-time proof confirms the continuous storage of user data over time. Compared with the single-copy replication proof used by Filecoin (which proves that a given storage provider is storing a unique copy of the customer's original data), the multi-copy recoverable storage proof adopted by CESS combines the challenge of space-time proof to help users secure through products such as DeShare , flexibly store their NFT data, and provide best practices for NFT storage.
