BMJ is oriented towards 5G and based on the in-depth development of the underlying technology of ipfs. Through the P2P transmission of nodes through slicing technology, it realizes the transmission of hundreds of megabytes of files in seconds. With the full activation of BMJ's distributed nodes, it realizes the effective connection of millions of devices around the world, serving the Internet Enterprises provide the cheapest and most efficient storage, network acceleration, edge computing and other services.

Project Background

Blockchain is considered to be the fifth subversive creation of the computing paradigm after personal computers, the Internet, and mobile social networks. Social productivity is computing power, means of production is data, and blockchain is the link between people and people, people and things, and things and things. In the future, human labor will be liberated, which is an era of automation. All business models will be rewritten, all values ​​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 integrated with artificial intelligence The Internet of Things, cloud computing, and big data combine to better serve human life. In December 2013, the founder of Ethereum, Vitali Buterin, proposed the Ethereum blockchain platform, applying smart contracts (smart contracts) to the blockchain, providing a broad development platform for decentralized application development, but the blockchain The imperfection of chain infrastructure still restricts the development of commercial applications.

Technical points

Transmission speed:BMJ has introduced a second transmission mechanism to improve the upload speed of data. When the data uploaded by a certain node enters 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 through the system network. In local storage, so as to achieve the effect of extremely fast transmission in seconds.
Data Exchange: The effect of data distribution is achieved by exchanging data blocks between nodes, and when the nodes are downloading data, they will also continuously upload the downloaded data blocks to the system network . At the same time, this exchange mechanism also has a warehouse to store the existing data blocks of all nodes, so as long as the hash value of the data is the same as the hash value in the want ist (want data block), you can directly Download all data blocks, not just limited to a corresponding node.
Storage structure: When BMJ stores data, in addition to storing the data in equal-sized fragments, it also adopts a special data storage structure. BMJ adopts a tree structure, which is mainly composed of nodes and links. Nodes store the relationship between data and subordinate links, and links store the Hash value of data. The linked data structure mainly consists of three parts: Name (subordinate data name), Size (subordinate data size), and Cid (subordinate data index). Under such a data structure, the hash value of the parent node is determined by the hash value of the child node, and the parent node contains the information of the child node, so when the biological data block is modified, only the modified biological data Blocks are copied and then modified, instead of copying the entire biological data, so the consumption of storage space will be greatly reduced.
