Sia Launches Decentralized Blockchain-based Storage Platform Similar to Filecoin and StorjDecentralized cloud file hosting service operator Sia has announced the launch of an automated peer-to-peer blockchain-based collaborative cloud for data storage, allowing users to create tailored storage plans with robust security protocols. Similar to decentralized storage projects Filecoin and Storj, Sia aims to create a trustless, fault-tolerant, file storage service.
The Sia platform stores personal and user data across multiple nodes and tracked by automated smart contracts. Files are protected through a multiple-stage process and encrypted with an algorithm called Twofish.
The strength of the platform relies on its Reed-Solomon-based file distribution system. All user data is split into several pieces as it enters the Sia client, leaving very few fractures necessary to recover the original data. These pieces of sensitive user information are padded to 4 megabytes, to protect user privacy. Finally, each padded piece is encrypted using unique encryption keys in the client side.
These security protocols are designed to prevent hackers from seizing user data of the Sia platform in an event of a data breach.
“Hosts receive an encrypted blob and are not given any information about where the other pieces of the file are. Even if they found out, they would still have to crack multiple encryption keys to recover the file. Cryptographic checksums are maintained by the client that alert the user to any tampering that the hosts may have attempted,” the Sia team told Bitcoin Magazine in an interview.
According to the team, the sophisticated encryption and decentralized file distribution system of the Sia platform could be used for decentralized application development. Its API enables developers to store files of the application directly into the Sia client, allowing third-party app users to directly access their customized data storage systems without revisiting the original client.
