Blockchain-based marketplace for file storage


Sia is a decentralized cloud storage platform aimed at giving users control of their data. Data is split into hundreds of erasure coded pieces and encrypted locally, and then each piece is uploaded to a separate host. A blockchain is used to create cryptographic contracts ensuring that hosts will only get paid if they actually store the data. Out of hundreds of hosts, only a fraction are required to recover the original file.

Anybody can join the network as a host and get income from the storage they contribute. This openness allows Sia to build and take advantage of a global network of small datacenters. Combined with advanced algorithms for storing and retrieving data, Sia is poised to be a highly competitive cloud storage platform. More information about the technology can be found on our website and in the 'doc' folder of the repo.

Sia is ready for use with small sums of money and non-critical files, but until the network has a more proven track record, we advise against using it as a sole means of storing important data.
