Blockchain prospers in a second mining fever long after the one that occurred in the 1840s. Assumed to be an ark carrying all the data into the brave new world, blockchain provides limited tickets that all the miners struggled to win. Ultimate resources have been wasted to involve the proof-of-work game in order to dig up bitcoins even in countries of the third world. So we strive to design another storage structure with self-destructing mechanism that can provide high-efficiency concurrency and which is more important security for all the users and all types of data. The data would vanish after expiration that could be set by the user in this structure named Bead Strand Model, and this humanitarian mechanism makes it more acceptable than blockchain by the people who concerned privacy and security in cloud environment.
