v1.3.4.1 (Capricorn)
SiaClassic 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), SiaClassic 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.
Traditional cloud storage has a number of shortcomings. Users are limited to a few big-name offerings: Google, Microsoft, Amazon. These companies have little incentive to encrypt your data or make it easy to switch services later. Their code is closed-source, and they can lock you out of your account at any time.
We believe that users should own their data. SiaClassic achieves this by replacing the traditional monolithic cloud storage provider with a blockchain and a swarm of hosts, each of which stores an encrypted fragment of your data. Since the fragments are redundant, no single host can hold your data hostage: if they jack up their price or go offline, you can simply download from a different host. In other words, trust is removed from the equation, and switching to a different host is painless. Stripped of these unfair advantages, hosts must compete solely on the quality and price of the storage they provide.
SiaClassic can serve as a replacement for personal backups, bulk archiving, content distribution, and more. For developers, SiaClassic is a low-cost alternative to Amazon S3. Storage on SiaClassic is a full order of magnitude cheaper than on S3, with comparable bandwidth, latency, and durability. SiaClassic works best for static content, especially media like videos, music, and photos.
Distributing data across many hosts automatically confers several advantages. The most obvious is that, just like BitTorrent, uploads and downloads are highly parallel. Given enough hosts, SiaClassic can saturate your bandwidth. Another advantage is that your data is spread across a wide geographic area, reducing latency and safeguarding your data against a range of attacks.
It is important to note that users have full control over which hosts they use. You can tailor your host set for minimum latency, lowest price, widest geographic coverage, or even a strict whitelist of IP addresses or public keys.
At the core of SiaClassic is a blockchain that closely resembles Bitcoin. Transactions are conducted in SiaClassiccoin, a cryptocurrency. The blockchain is what allows SiaClassic to enforce its smart contracts without relying on centralized authority. To acquire siaclassiccoins, use an exchange such as Bittrex, Yunbi, or Bisq.
To get started with SiaClassic, check out the guides below:
Usage
SiaClassic 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, siaclassicd and siaclassicc. siaclassicd is a background service, or "daemon," that runs the SiaClassic protocol and exposes an HTTP API on port 7780. siaclassicc is a command-line client that can be used to interact with siaclassicd in a user-friendly way. There is also a graphical client, SiaClassic-UI, which is the preferred way of using SiaClassic for most users. For interested developers, the siaclassicd API is documented here.
siaclassicd and siaclassicc are run via command prompt. On Windows, you can just double-
click siaclassicd.exe if you don't need to specify any command-line arguments.
Otherwise, navigate to its containing folder and click File->Open command
prompt. Then, start the siaclassicd service by entering siaclassicd and pressing Enter.
The command prompt may appear to freeze; this means siaclassicd 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 siaclassicc (in a separate command prompt) or SiaClassic-
UI to interact with siaclassicd. From here, you can send money, upload and download
files, and advertise yourself as a host.
Building From Source
To build from source, Go 1.10 must be installed
on the system. Make sure your $GOPATH is set, and then simply use go get:
go get -u gitlab.com/moderndevgroup/SiaClassic/...
This will download the SiaClassic repo to your $GOPATH/src folder and install the
siaclassicd and siaclassicc 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 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.
