# CESS Feb 2024 Monthly Technical Report By [CESS_Network](https://paragraph.com/@cess-network) · 2024-03-04 --- **CESS Introduction** ===================== [**CESS**](https://cess.cloud/) **(Cumulus Encrypted Storage System) is a blockchain powered decentralized storage and content delivery network (CDN) infrastructure for Web3.** Users and creators alike use the platform for on-chain data sharing, whilst builders can develop and deploy DApps. Offering the most optimal Web3 solution for storing and retrieving high-frequency dynamic data, CESS reshapes the value distribution and circulation of data assets whilst ensuring data sovereignty and user privacy. By utilizing **a decentralized physical infrastructure network (DePIN) model,** CESS drives mass deployment of network nodes globally through incentives. CESS network consists of four layers: **Blockchain Layer, Distributed Storage Resource Layer , Distributed Content Delivery Layer, and Application Layer.** [**CESS**](https://www.cess.cloud/)’s R²S consensus mechanism coordinates the network resources and network load, guarantees data security and integrity through proprietary technologies with data ownership protection, technologies such as Proof of Data Reduplication and Recovery (PoDR²), Multi-format Data Rights Confirmation (MDRC), and decentralized proxy re-encryption. [CESS](https://www.cess.cloud/) aims to be the first decentralized storage network that supports large-scale commercial applications. [CESS](https://www.cess.cloud/) is also compatible with EVM and WASM, and the underlying development framework Substrate is also friendly to cross-chain applications. Its technology stack can support most Web3 applications and the development needs of enterprise-level applications. **Important Technological Deliveries** ====================================== **Blockchain Network:** ======================= _Current testnet:_ [_v0.7.6_](https://github.com/CESSProject/cess/releases/tag/v0.7.6) _consists of consensus and storage nodes._ **_Consensus node_** _maintain the world state of the_ [_CESS_](http://www.cess.cloud/) _network (by CESS Node) and serve as the “data authentication station” (by TEE Worker)._ **_Storage node_** _provide verifiable storage space and serve as the “data storage pool” in the CESS network._ **Consensus Nodes \[**[**v0.7.7**](https://github.com/CESSProject/cess/releases/tag/v0.7.7)**\]** * Fixed the issue of CESS Node failing to issue mining rewards to storage nodes. * Completed the online upgrade of CESS Node, increasing the maximum number of random challenge penalties. * Optimized the TEE Worker handover security mechanism, improving the Ceseal program upgrade process. * Optimized the TEE Worker active file preprocessing process, significantly improving data transmission efficiency and stability. * Fixed the issue of CESS Node benchmark testing tool errors. * Refactored the whitelist module of the Ceseal program to prevent registration of untrusted TEE Workers. * Fixed the issue of the Ceseal program failing to hand over shared keys. * Fixed the issue of TEE Worker being blocked when calculating Tag, causing all services to be unusable. * Improved TEE Worker chain registration function, adding checks for security parameters such as timestamps and expiration times. * Fixed the issue of uncleaned registration information on the chain after TEE Worker exits. * Completed the writing and testing of benchmark cases for each pallet of CESS Node 0.7.6 version. * Fixed the issue of TEE Worker failing to verify user active file Tag signatures. * Adjusted the idle space proof algorithm parameters to increase system security by increasing idle space authentication difficulty. * Adjusted details such as node penalty mechanism and exit mechanism in the economic model to make it more practical. * Fixed the issue of CESS Node being unable to effectively verify the tagging results of user active files. **Storage Nodes \[**[**v0.7.10**](https://github.com/CESSProject/cess-bucket/releases/tag/v0.7.10)**\]** * Fixed the issue of random challenge failure due to incomplete tag calculation during file recovery. * Fixed the issue of ineffective execution of appending pledge command. * Fixed the issue of ineffective mining reward claim command. * Fixed the issue of requiring installation of GLIBC\_v2.32 and GLIBC\_v2.34 at runtime. * Added the function to obtain shared keys. Keys can be reobtained when lost. * Fixed the issue of being unable to identify whether the TEE Worker endpoint is invalid. * Fixed the issue of inability to work normally after failing to obtain shared keys. * Upgraded the way of passing data to TEE Worker to streaming transmission, improving bandwidth resource utilization. * Improved the startup process to automatically pledge when the signing account is the same as the pledging account. [_CESS_](https://www.cess.cloud/) _is a blockchain powered decentralized storage and content delivery network (CDN) infrastructure for Web3. By utilizing a decentralized physical infrastructure network (DePIN) model, CESS drives mass deployment of network nodes globally through incentives. The first of its kind, decentralized object storage services (DeOSS) by_ [_CESS_](https://www.cess.cloud/) _has significantly contributed to the gradual enrichment and flourishing of the product ecosystem within the_ [_CESS_](https://www.cess.cloud/) _network, online file sharing tool (DeShare), and public chain snapshot storage services have been incubated. The developments for this month are as follows:_ **Decentralized Object Storage Service (**[**DeOSS**](https://github.com/CESSProject/DeOSS/releases/tag/v0.3.2)**)** * Completed the development of the js-sdk Metamask wallet front-end version, supporting operation in the browser. * Fixed the issue of inability to work normally due to disk fullness. * Added the function of querying TEE Worker endpoints in go-sdk. * Completed the development of the js-sdk Metamask wallet transfer tool, supporting payment of CESS tokens through Metamask. * Completed the update of go-sdk to adapt to the latest CESS chain API. * Completed a large number of file upload stress tests. **Blockchain Explorer (**[**Substats**](https://substats.cess.cloud/)**)** * Implemented the function of parsing blocks in the background and writing them into the database. * Completed the construction of the background service framework and routing table configuration. * Modified the decimal places of TECESS tokens to 18 digits. * Fixed the issue of data overflow caused by declaring excessive storage space. * Completed the establishment of storage node-related information tables in the new version of the background database. **CESS Website (**[**cess.cloud**](https://cess.cloud/)**)** * Updated the layout and responsive styles of the Events/News page on the official website, improving page display details. * Added status filtering function on the Events page. * Added blog forwarding function on the official website Blog page. **Technical Documentation and References** ========================================== GitHub: [https://github.com/CESSProject](https://github.com/CESSProject) WiKi: [https://docs.cess.cloud/core/](https://docs.cess.cloud/core/) CIPs: [https://github.com/CESSProject/CIPs](https://github.com/CESSProject/CIPs) **Join us** =========== [**CESS website**](https://www.cess.cloud/) **|** [**Twitter**](https://twitter.com/CESS_Storage) **|** [**Telegram**](https://t.me/CESS_Storage_official) **|** [**Discord**](https://discord.gg/UDZaBaDhcv) **|** [**Github**](https://github.com/CESSProject) **|** [**Medium**](https://medium.com/@CESS_LAB) **|** [**LinkedIn**](https://www.linkedin.com/company/cumulus-encrypted-storage-system) **|** [**Instagra**](https://www.instagram.com/cess_storage/?utm_source=ig_web_button_share_sheet&igshid=OGQ5ZDc2ODk2ZA%3D%3D)**m｜**[**YouTube**](https://www.youtube.com/@cess_storage2312) --- *Originally published on [CESS_Network](https://paragraph.com/@cess-network/cess-feb-2024-monthly-technical-report)*
