META Storage

META Storage is a data onramp that can realize automatic storage transactions. In addition, it is also equipped with Access Control FVM and an entrance that can access the Retrieval Oracle. Meta Storage is comprised of multiple APIs, protocols, FVM smart contracts, and a visual interface. It provides a fast implementation of web3 storage solutions for DataDAO, Public Chains, DAPPs, Web2 companies, etc.

Our Goal: META Storage aims to be a user-friendly and convenient data onramp. Through our onramp, various data owners (for example, web2 enterprise users, DAPP, DATADAO or individuals) can store data in the decentralized network without consuming more resources to build storage infrastructure.

Meta Storage includes the following 5 parts: Data Onramp: Different types of data are passed through a set of APIs to form corresponding types of data channels. Data Aggregator: the ability to aggregate user submissions in a trustless decentralized manner offline. FVM-based Access Control: Give the smart contract a private key on the public blockchain, allowing the user to decide who can access their data. FVM-based auto storage: Match user data to the best SP in the fastest way. FVM-based Retrieval: Stable retrieval service under preset conditions.

What makes META Storage Unique? The METAStorage uses smart contracts on the FVM to achieve the following features: Access Control allows users to customize file retrievers For example, data owners can auction valuable content for economic benefits, and control the decryption of files through "image for image" conditions for entertainment and marketability. Auto Storage significantly improves the convenience of data owners For example, after setting expected prices, time, backups, etc. at the entrance, METAStorage ensures that the data will be quickly stored on the network according to the user's expectations. Built-in retrieval oracle allows users to receive stable retrieval services under preset conditions For example, data owners and RPs can pre-set future retrieval conditions (e.g. $0.5/G) before storing data, and RPs must fulfil their obligations when data owners retrieve data in the future META Storage can connect to various ecosystems and applications, greatly enhancing the value of data usage META Storage lowers the barrier for data owners to use web3 storage such as Filecoin/IPFS by providing a more user-friendly platform

Our storage-side API is written in golang. The front-end page is built with vue FVM contracts are written in rust. We have build 2 Fvm contracts added in our data onramp. We are to build the MetaStorage which could achieve some unique features by using smart contracts on the FVM.It's a user-friendly and convenient data onramp. MetaStorage includes 5 parts,Data Onramp, Data Aggregator,FVM-based Access Control,FVM-based auto storage,FVM-based Retrieval. It's architecture as bleow, If the user wants to upload his valuable data to the premium miner,he just need to use the storage onramp which provides both Storage API and WebUI. when the enroll factory receive the request from the storage onramp,it will register to the deal factory,data aggregator factory and access control factory.The user's data will also stored in our ipfs storage to achive hot backup,when it has stored in the miner,will be deleted in the ipfs sotrage. The deal factory will also register to the scheduler,then the scheduler will do something such as checking the expiration of deal,doing query ask,backing up data,to make sure this deal is successfully completed. The data aggregator factory will aggreate user's submissions in a trustless decentralized and offline manner. The access control factory will set up a series of authentication rules, allowing the users to decide who can access their data. If all goes well,the market will publish the deals to the best miner to seal and storage the user's valuable data then also provide the data retrieval. All this will deployed on the FVM,thus realizing the auto storage to the users in the fastest way and stable retrieval service under preset conditions.
