Binaries can be found at our website. Code for the graphical front-end can be found at the Sia-UI repo.
Sia is a new 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.
This release comes with 2 binaries, siad and siac. siad is a background service, or "daemon," that runs the Sia protocol, and siac is a client that is used to interact with siad. Siad exposes an HTTP API on 'localhost:9980' which can be used to interact with the daemon. There is a front-end program called Sia-UI which can be used to interact with the daemon in a more user-friendly way. Documentation on the API can be found in doc/API.md.
siad and siac are run via command prompt. On Windows, you can just double-
click siad.exe if you don't need to specify any command-line arguments.
Otherwise, navigate to the sia folder and click File->Open command prompt.
Then, start the siad service by entering siad and pressing Enter. The
command prompt may appear to freeze; this means siad is waiting for requests.
Windows users may see a warning from the Windows Firewall; be sure to check
both boxes ("Private networks" and "Public networks") and click "Allow
access." You can now run siac in a separate command prompt to interact with
siad. From here, you can send money, mine blocks, upload and download
files, and advertise yourself as a host.
To build from source, Go 1.6 must be installed
on the system. Then simply use go get:
go get -u github.com/NebulousLabs/Sia/...
This will download the Sia repo to your $GOPATH/src folder, and install the
siad and siac binaries in your $GOPATH/bin folder.
To stay up-to-date, run the previous go get command again. Alternatively, you
can use the Makefile provided in this repo. Run git pull origin master to
pull the latest changes, and make release-std to build the new binaries. You
can also run make test and make test-long to run the short and full test
suites, respectively. Finally, make cover will generate code coverage reports
for each package; they are stored in the cover folder and can be viewed in
your browser.

I can't add storage folders on Windows.
Currently, admin privileges are required to add storage folders on Windows. Close siad and run it from an admin command prompt. Future versions will not require admin privileges.
-
I can't connect to more than 8 peers.
Once Sia has connected to 8 peers, it will stop trying to form new connections, but it will still accept incoming connection requests (up to 128 total peers). However, if you are behind a firewall, you will not be able to accept incoming connections. You must configure your firewall to allow Sia connections by forwarding your ports. By default, Sia communicates on ports 9981 and 9982. The specific instructions for forwarding a port vary by router. For more information, consult this guide.
Sia currently has support for UPnP. While not all routers support UPnP, a majority of users should have their ports automatically forwarded by UPnP.
-
I mined a block, but I didn't receive any money.
There is a 144-block confirmation delay before you will receive siacoins from mined blocks. If you still have not received the block reward after 144 blocks, it means your block did not make it into the blockchain.

v1.0.0 represents a landmark in the development of Sia. In accordance with semver, API compatibility will not be broken until v2.0.0, which is not on the current development roadmap. In other words, developers should feel confident leveraging the siad API in their own applications. When new functionality is added, it will be added in a backwards-compatible manner. New routes may be added, and new parameters may be added to existing routes or responses, but none of the routes present in v1.0.0 will be removed, nor will any of their parameters or response fields be removed.
-
siad now supports API authentication, enabled by the
--authenticate-apiflag.
Please tell us about any problems you run into, and any features you want! The advantage of being a beta user is that your feedback will have a large impact on what we do in the next few months. Thank you!
