here a few points from the Sia team:
We've really been focused on decentralization. And I mean this in the 'sovereign' or 'trustless' sense of the word. When our competitor Storj says 'it's decentralized', what they mean is that there are a couple of parties out there who most people trust, and they have the freedom to pick which one they want to trust. At great expense, you also have the ability to be one of those parties. Sia on the other hand does not force you to trust anyone. It's a lot more powerful than picking who to trust, you can just know that everything is working and that nobody can stab you in the back.
Sia hosts are high quality. To be a host on Sia, you have to put forward money that promises you will keep the data. This means that we don't get as many flaky hosts, because being a flaky host means taking your money and pouring it down the drain. This also means that we have a lot fewer hosts, but most importantly it means that your files are safer, because when you do pick a host you know that they have a strong incentive to keep your files safe.
Sia is marketplace based, where as most of our competitors are prescription based. Renters have full control over which hosts they use. Hosts are picked per-machine, instead of at the protocol level. That means that Chinese users can focus on picking hosts in China, American users can focus on American hosts, etc. Or if your application is more bandwidth intense, you can pick hosts with cheaper bandwidth costs as opposed to hosts with cheaper storage costs, etc.
Sia is really focused on security. We've had bitcoin core devs review our architecture, we've had bitcoin cryptographers read our signature code, and in general we think about security every time we make a design decision. Most people who are able to review the security of protocols like Sia tend to say that Sia has much stronger security.
What do you Steemers think of Sia-tech/storage ?
I personally got really interested in the project and I'm planning on buying more of them in the short future.
Thanks and hoping for some nice reply's
