BMJ is in-depth development for 5G based on ipfs underlying technology, and uses slicing technology to transmit P2P to nodes and realizes the transmission of hundreds of mega-files in seconds. With the full launch of BMJ distributed nodes, it realizes effective links between millions of devices around the world, providing Internet companies with the cheapest and most efficient storage, network acceleration, edge computing and other services.

Project background

Blockchain is considered to be the fifth subversive Census in the computing paradigm after personal computers, the Internet, and mobile social networks. Social productivity is computing power, means of production are data, and blockchain is a group link that links people, people and things, and things. In the future, human labor will be liberated, and that is an era of automation. All business models will be rewritten, all value will be tokenized, and a series of greater collaborations such as data transactions and computing power sharing will release human creativity. At the same time, blockchain will be in line with artificial intelligence Internet of Things, cloud computing, big data, etc. to better serve human life. In December 2013, Ethereum founder Vitali Buterin proposed the Ethereum blockchain platform to apply smart contracts to blockchain, providing a broad development platform for decentralized application development, but the imperfect blockchain infrastructure still restricts the development of commercial applications.

Technical Points

Transmission Speed:BMJ introduced a second transfer mechanism to improve the upload speed of data. After the data uploaded by a certain node is placed in the system network, it can be determined whether the data exists in the network through hash value verification. If it exists in the network, the file can be copied to the uploader's local storage through the system network, thereby achieving the effect of extremely fast transmission in seconds.
Data Exchange:The data distribution effect is achieved by exchanging data blocks between nodes, and while the node downloads data, it will continue to upload the downloaded data blocks to the system network. At the same time, this exchange mechanism also has a warehouse to store data blocks that all nodes already have. Therefore, as long as the hash value of the data is the same as the hash value in want ist, the data block can be downloaded directly, not limited to the corresponding node.
Storage structure:BMJ uses a special data storage structure in addition to storing data of equal size. BMJ adopts a tree structure, mainly composed of nodes and links. The node stores the relationship between data and subordinate links, and the link stores the hash value of the data. The linked data structure mainly consists of three parts: Name (lower data name), Size (lower data size), and Cid (lower data index). In this data structure, the hash value of the parent node is determined by the hash value of the child node. The parent node contains information of the child node. Therefore, after the biological data block is modified, it is only necessary to copy the modified biological data block and then modify it, rather than copying the entire biological data, which greatly reduces the consumption of storage space.
