Siacoin is the first distributed storage track project with its native token SC. Different from traditional cloud storage platforms, Siacoin's stored data is encrypted distributed storage, which makes the data more reliable and effectively utilizes underused hard disks in the world, reducing costs.

SC tokens were first issued around July-August 2015, with an issue price of approximately $0.000046. The current SC token price is $0.002864, which has increased more than 60 times compared to the issuance period. The current circulation of SC is about 51.4 billion pieces, and the total market value is about 149 million US dollars.

The core of Siacoin technology is Reed Solumn encoding technology. When a file is uploaded to the client, Siacoin will cut the file into multiple copies and save 3 backups, which are stored in different hosts, thus effectively ensuring data privacy. This storage method eliminates the need for users to trust centralized companies and servers like traditional cloud storage platforms, thus having higher security.

Siacoin was initiated by David Vorick in 2013. Its project prototype is the Nimbus network. Its business model has been improved and currently supports the storage of video streaming files. However, with the development of the decentralized storage track, the development of Siacoin is not as expected, which may be due to the slow progress of the project in technology research and development and the lack of marketing promotion.
