Store your data safely

A beautiful platform, called Sia (still in beta), represents one (or the only one?) of the few working platforms that allow decentralized data storage based on the blockchain. An excerpt from its forum:

Sia is an actively developed decentralized storage platform. Users all over the world contribute disk storage from their computers to form a decentralized network.

Anybody with siacoins can rent storage from hosts on Sia. This is accomplish via "smart" storage contracts stored on the  Sia blockchain. The smart contract provides a payment to the host only after the host has kept the file for a given amount of time. If the host loses the file, the host does not get paid.

(Note one of its splendid features - erasure coding - a near future must for the big data.)
