The invention discloses a credible investment and financing complete dispatching file distributed large file point storage method based on a block chain, and relates to the technical field of Internet. The credible investment and financing exhaustion scheduling file distributed large file point storage method based on a block chain comprises the following steps: an investment and financing exhaustion scheduling file owner uploading locally stored large file data, and recording file uploading behaviors of all parties and structured data identifiers corresponding to files by using the block chain; wherein the large file is cut into a plurality of 256k file blocks, and the file blocks are stored in a block chain network in a distributed manner after the asymmetric secret key is encrypted; meanwhile, providing a complete node distributed cluster, ensuring that the storage service can continue to be provided after a common single node is crashed. The invention provides a large file block chain point storage method, and improves the block chain storage performance.
Description
technical field [0001] The invention belongs to the technical field of the Internet, and in particular relates to a block chain-based method for distributed large file point-like storage of credible investment and financing due diligence files. Background technique [0002] With the continuous development of blockchain technology, its application in various fields has gradually expanded. In the investment and financing process, due diligence documents have always been the most important data asset information for both investment and financing companies. Due to the complexity and variety of due diligence documents In the original environment, the storage method of large files is mostly centralized, the storage cost is high, the storage type compatibility is not strong, and the tampering is high; the mainstream blockchain Technically, the size of the data that can be stored is limited. The limitation of IPFS technology is that it is in an open source and open Internet environm...
