CESS builds a new paradigm for storage: storage space leasing

CESS, as the first blockchain network in the industry to support large-scale commercial storage, is redefining the standards of decentralized cloud storage through innovative technologies and storage services like DeOSS (Decentralized Object Storage Service), committed to providing the best solutions for the storage and retrieval of high-frequency dynamic data in Web3.

To truly realize the vision of Web3, industry pioneers are actively exploring feasible paths from different dimensions. Storage, as a core infrastructure, will lay the foundation for whether the Web3 industry can achieve large-scale adoption and explosion. CESS ensures data security, privacy, and flexibility while empowering users with permission management, allowing them to easily authorize and share their data, enabling online sharing and real-time updates, safeguarding users' data ownership, privacy rights, and value rights, bringing unprecedented advantages in data performance, storage, and management for enterprise-level commercial applications and individual users.

Therefore, CESS is not just a decentralized distributed cloud storage system, but also a decentralized cloud storage data network infrastructure and a decentralized data value interconnection network; CESS represents a new beginning, a new storage paradigm, guiding us towards a data valorization era that is safer, more efficient, and more autonomous.

In the article "CESS Builds a New Storage Paradigm: Smart Space Management," we introduced CESS's Smart Space Management, understanding CESS's advantages and innovations from the classification and efficient utilization of storage space. This article will introduce CESS's storage space leasing, continuing to deconstruct what kind of new storage paradigm CESS has built for the industry.

Storage Space Leasing

Storage space leasing is divided into commercial-grade storage and permanent storage, with the main differences reflected in the time period and usage rights. Commercial-grade storage is suitable for medium- and short-term use of space, allowing users to flexibly add, delete, query, and modify data. The minimum leasing period for commercial-grade storage is 30 days, and the space can be expanded and renewed at any time; permanent storage is suitable for long-term use, where data can only be read after being written.

Thus, the pricing and calculation methods for commercial-grade storage and permanent storage are also different, as described below:

- Commercial-grade Storage

The storage space leasing service is based on oracle dynamic pricing, using USDT as the anchor asset.

The leasing price is dynamically adjusted based on the current space occupancy rate; when the occupancy rate is low, the leasing price decreases, and when the occupancy rate is high, the leasing price increases.

Overall network space occupancy rate = Occupied space / Total verified space in the network

- Permanent Storage

The fees for permanent storage are calculated using an on-chain formula, with the basic formula being: Storage fee = File size (MB) * Network fee + Tip

The network fee is dynamically adjusted based on the current space usage rate; when the usage rate is low, the network fee decreases, and when the usage rate is high, the network fee increases.

The tip is determined by the user.

Space Leasing Process

Users with data storage needs must first access the CESS chain to obtain the current storage space prices and complete the purchase of storage space by initiating a transaction.

Once the purchase is successful, users can store data in any format in the storage space they have purchased. Users will upload data through the CESS system's API.

• To ensure data security and privacy, the client first encrypts the data before sending it, then sends the data to the cache gateway (DeOSS gateway), where the authorized gateway places a storage order on the chain on behalf of the user. Next, the chain network allocates storage nodes, and the gateway preprocesses the data, including data backup, tagging, slicing, etc., and finally stores all slices in these storage nodes.

In the CESS system, storage miners do not directly engage with users for data storage services, but only need to provide storage capacity to earn block rewards.

• When storage miners connect to the CESS network, their resources will be integrated into the CESS system's management, and the CESS blockchain network will randomly distribute data blocks to storage miners, ensuring that the amount of data stored by each miner is uniform. However, storage miners are obligated to ensure that the data stored on their nodes is complete, primarily verified through CESS Multi-Backup Recoverable Storage Proof (PoDR²) and other mechanisms to validate data integrity. If data corruption occurs, they will face severe penalties, including the deduction of the pledged CESS Tokens.

The leasing process of CESS is illustrated in the diagram below.

Comparison of Storage Service Provision Methods

As a storage service provision method of CESS, space leasing offers greater flexibility and scalability compared to the direct storage provided by Filecoin and the permanent storage offered by Arweave, empowering users with data management rights, and is suitable for short/long-term storage and permanent storage, applicable to both user data storage and large-scale commercial data storage. The specific comparison is as follows:
