DDshare

Inspiration

DDshare aims to build Decentralized DataSharing Infrastructure. DDshare‘s mission: “To store the world's data and share it to the world." DDshare's deck link: https://hub.textile.io/ipfs/bafybeicgdjsy77vg3ilg5c5he2kxjeogqx6t3oceockm5zdb4hinvbthyy

Problems:

• Identity information is controlled by the service platform
• Centralized storage of data, controlled by centralized service providers, very insecure
• The data storage platform is too differentiated, and the life cycle may be short (burning money to death)
• The data storage platform charges fees by controlling download speed and other unreasonable behaviors
• The resource link of the data is easy to expire and lose, resulting in the data cannot be retrieved
• Data cannot be shared effectively (data is controlled centrally and cannot be shared)
• Duplicate data and excessive junk data make data acquisition difficult
• Content creators cannot transfer data to other platforms (data will be lost if the platform account is cancelled)
• Data sharing and reward economy are difficult to combine

Solution:

• All data are built on the next protocols that power the web3 (IPFS,Filecoin,Textile,NFT.storage,Web3.storage)
• Decentralized registration brought by LikeCoin
• Data generates NFT and on-chain transaction -Join ISCN to create a basic model for digital content registration -Combining NFT and LikeCoin to bring economic system to data -Establish a search index through the CC protocol and metadata of the data, and access the search engine

Our core is to store and share humanity's data . IPFS-based content addressing will be an index of data, and the metadata of data will be a secondary index of data. Everyone can obtain the data they want and share their existing data and obtain token economic rewards through sharing behaviors, and the data can be stored safely and stably for a long time. The humanity's data will have its own economic reward model. Anyone can get benefits from sharing,data interaction and can also act as a data verifier to determine the quality of the data to obtain benefits, and at the same time to maintain the data high quality.

IPFS has four main compenets:

Decentralized Registry & Decentralized storage:

• Use DID protocol to reimagined for a user-centric web
• Encrypt private data through decentralized user authentication
• Perfect cross-platform interactive experience
• Multiple reliable IPFS storage node options( NFT.storage, Web3.storage,Textile,Pinata)
• Use Filecoin for safe, durable and reliable storage and retrieval of data

Decentralized Sharing :

• Decentralized user license agreement signing
• Establish a metadata infrastructure for data
• Data sharing token economy system is established
• Data NFT trading system establishment

Decentralized Searching:

• Search by data metadata
• The search weight of the data is weighed by the metadata and the weight of the record on the chain
• Shared data can be accessed by search engines via ShareAPI
• Private data is searched through private API interface

Built With

• filecoin
• ipfs
• likecoin
• polygon
