Sia is a new decentralized cloud storage platform that radically alters the landscape of cloud storage. By leveraging smart contracts, client-side encryption, and sophisticated redundancy (via Reed-Solomon codes), Sia allows users to safely store their data with hosts that they do not know or trust. The result is a cloud storage marketplace where hosts compete to offer the best service at the lowest price. And since there is no barrier to entry for hosts, anyone with spare storage capacity can join the network and start making money.
 
 Sia splits apart, encrypts, and distributes your files across a decentralized network. Since you hold the keys, you own your data. No outside company can access or control your files, unlike traditional cloud storage providers.

Gin is a web framework written in Go (Golang). It features a martini-like API with much better performance, up to 40 times faster thanks to httprouter. If you need performance and good productivity, you will love You can add global, per-group, and per-route middlewares, thousands of nested groups, nice JSON validation and rendering. And the performance will be still great. Gin uses httprouter internally, the fastest HTTP router for Golang. Httprouter was created by Julien Schmidt and it’s based in a Radix Tree algorithm.
 
It has very good middleware support, A incoming HTTP request can be handled by a chain of middlewares and the final action. For example: Logger, Authorization, GZIP and finally post a message in the DB.
 
Gin can catch a panic occurred during a HTTP request and recover it. This way, your server will be always available.
