[ANN] Metadisk - Blockchain Based File Sharing - Powered by Storj May 14, 2014, 05:59:45 PM

Last edit: May 25, 2014, 02:04:46 PM by super3 #1 What is Metadisk?



Metadisk is the first storage focused blockchain-distributed web application, which means that there is no central authority or entity that controls your data. Metadisk runs on top of the



How does it work?



After the file is encrypted and uploaded, a SHA-256 hashing algorithm will be applied, which produces a hash of the file that serves both as a unique identifier and a way to detect file tampering. The generated hash will then be stored in a block chain entry. Metadisk communicates with the Storj network to find available storage resources, then transfers the encrypted file to three (3) separate locations. This 3-time storage complies with the cloud storage redundancy standard. Because all data that enters the network is encrypted, malicious nodes and thieves cannot open, copy or modify files, because they do not have access to the decryption keys for them.



The current functions and specifications that Metadisk offers are just a small prototype of Storj. Metadisk allows us to experiment with many methods and algorithms, while still providing user security, privacy, scalability, and cost savings over many current cloud storage systems.
