CESS won the Asia-Pacific championship at the Polkadot Hackathon!

The results of the "kick-off" event of the Polkadot Global Hackathon in the Asia-Pacific region have been announced, with the project FMD-CESS submitted by the CESS Lab team winning the first prize in the "Blockchain Development" category of the Polkadot Global Hackathon Asia-Pacific region!

This first stop of the Polkadot Global Hackathon kicked off in the Asia-Pacific region (APAC) and will subsequently take place in North America, Europe, Latin America (LATAM), the Middle East, and North Africa (MENA). The competition in the Asia-Pacific region is hosted by the Web3 Foundation and Parity Technologies, organized by AngelHack, and officially opened for project submissions on October 22, closing on December 12.

The entries for this competition can be divided into three categories: Blockchain Development (building blockchain projects based on Substrate), Development Propositions (including development tools, wallets, governance, etc.), and Technical Documentation (tutorials, guides, etc. related to hackathon projects or Polkadot). CESS Lab won the first prize in the Blockchain Development category, which is also the highest prize, most rewarding, and most valuable first prize among all awards in this hackathon.

The CESS Lab's entry FMD-CESS is a data trading platform based on the decentralized cloud storage network CESS. The participating developers fully utilized CESS's advantages in data interaction efficiency and security to develop a data element market that enables peer-to-peer trusted transactions under the premise of data ownership and privacy protection in a decentralized network, aiming to become a data element trading market in the Web3 ecosystem and promote the value interconnection of data assets.

The overall system architecture is shown in the figure. There are four components, including FMD-CESS, CESS Cloud Data Network, CESS Storage Network, and Block Explorer.
· FMD-CESS (web-app): A web platform for users to upload, search, purchase, and download data, supporting various data formats and providing one-stop data trading services and public data search functions. In addition, it has implemented a data permission confirmation mechanism.

· CESS Cloud Data Network (cess-node): The CESS Cloud Data Network stores the metadata of all data uploaded by users. This layer of the network is a decentralized cloud storage network based on Substrate developed by CESS Lab, which is currently in the optimization phase and will first launch on the BSC testnet in the future.

· CESS Storage Network: A network established by storage miners and scheduling miners. When users upload data, it will be distributed to different storage miners through scheduling nodes. Similarly, when users download data, they will also obtain data from storage miners through scheduling nodes.

· Block Explorer (cess-ui-js): Custom-built for CESS, modified from polkadot-js-app, allowing users to obtain blockchain information from multiple dimensions.
The CESS Lab hackathon team consists of developers from India, Teh Sunn Liu, Yeou Sunn Liu, Jack Liu, and domestic developer Ted Zhang. Over nearly 8 weeks, the team not only completed the aforementioned development but also provided a Faucet for users to mint test tokens. During the hackathon, the team overcame numerous obstacles, especially implementing a multi-proof mechanism for decentralized storage under the Substrate framework (such as PoSt, PoRe, etc.), achieving usability before the hackathon ended. In the future, the application will continue to be maintained and developed post-hackathon, with features such as API-based data trading, design of data and transaction standards, data tracking, and risk control to be launched. Completing a relatively complex data application in blockchain during a short and intense hackathon demonstrates the strong technical capabilities of the CESS Lab development team and their expertise in data storage and related fields. In the future, CESS will undoubtedly become an essential data infrastructure for Web3.

Finally, thanks to the efforts of the development team, CESS will bring more surprises, so stay tuned!
