Computer-implemented system and method to enable secure storage of large-scale blockchain through multiple storage nodes

摘要

The protocol is described, which: (i) allows storage nodes to be rewarded for maintaining a public blockchain, and (ii) the integrity of the blockchain with the help of the Proof-of-Blockchain Storage (PoBS) scheme. To confirm. This protocol provides a method of cryptographically checking whether a data file stored on a remote server is intact using a challenge-response method. This protocol is protected from man-in-the-middle attacks. Malicious peers cannot deliver a response and send a challenge to a third party who is storing data. The system is also publicly identifiable.
