Technical Highlight
The Proof of Data Reduplication and Recovery (PoDR²) protocol is designed to ensure the validity and availability of stored data by challenging storage nodes regularly. To prevent data loss and maintain data integrity in any situations, such as when some storage nodes are offline or leaving the network, data fragments are stored redundantly.
The Proof of Idle Space (PoIS) is designed to verify whether storage nodes have honestly contributed available storage resources to the CESS network, which will be used to store user data. Storage nodes can also exchange their storage contributions for incentives.
The CESS network aggregates storage space contributed by storage nodes from around the world in what we call Smart Space Management. For storage nodes, the committed storage space will be flexibly allocated and used by the CESS network. For users, it makes the CESS network like cloud storage, with features of horizontal scalability, elasticity, and durability.
Unlike the storage space bidding of alternative decentralized storage protocols, CESS users only need to bid on a single price point on CESS storage. CESS middle layer has a pricing mechanism to calculate an optimized price point for storage users while balancing the incentives of storage providers.
Launch in 2024 product roadmap
CESS is compatible with IPFS standard and allows developers to integrate their dApps with an array of storage solutions that utilize IPFS. Data stored on CESS can also be addressed with cryptographic hashes, making the content immutable and tamper-resistant.
Launch in 2024 product roadmap
Proxy Re-encryption Technology (PReT) is built on top of Public Key Encryption to allow users to authorize decryption permissions to others without disclosing the data's contents. User data is also processed and accessed in Trusted Execution Environment (TEE) within the storage nodes.
Launch in 2024 product roadmap
Data indexing and Decentralized Content Delivery Network (DCDN) improve searching and download speed from user endpoints. Consensus mechanism has been iterated on top of Polkadot GRANDPA to achieve low gas fees and high transaction throughput.
Launch in future
Data ownership can be verified with Multi-format Data Rights Confirmation technology (MDRC). This protocol extracts fingerprints from all data and permanently stores them on-chain for traceability.
