SiaPrime does not run on S3. Our network is made up of individuals and datacenters contributing storage to a network of decentralized storage nodes. Because there is a lot of spare storage in the world, we are capitalizing assets already paid for. At the same time, there is a lot of overhead built into the S3 pricing model. Several traditional cloud companies significantly undercut AWS prices today. With our decentralized storage product, you get the best of all worlds; great pricing, a fully S3 compatible infrastructure and decentralization to protect your data from centralized breach/failpoints. Nobody can censor your data because it is sharded via erasure coding and always encrypted at the client before upload to the network. Using EC means any 10 hosts out of 30 can restore your data making the service far more secure than traditional centralized cloud services. Plus, we do on-premise and hybrid implementations that allow IT admins to decentralize files throughout the enterprise to save money.

Our product "works" today in a very basic version (not yet S3 compatible). We expect to have a shipping version by end of 2019 for business customers.
