What is Sia?

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. Sia stores tiny pieces of your files on dozens of nodes across the globe. This eliminates any single point of failure and ensures highest possible uptime, on par with other cloud storage providers.

Using the Sia blockchain, Sia creates a decentralized storage marketplace in which hosts compete for your business – this leads to the lowest possible prices, on average 1/10th the cost of current cloud storage providers. Renters pay using Siacoin, which can also be mined and traded.

Sia is open source. Over a dozen individuals have contributed to Sia’s software, and there is an active community building innovative applications on top of the Sia API. If you want to learn about what motivated Sia and its vision is, we recommend the Sia Ethos blog post by lead Sia developer David Vorick.

Download the Wallet

The only official wallets are Sia-UI and Sia Daemon, available from the Sia Apps page or the Nebulous Labs Github. One of the core developers has created an offline Sia wallet, though it is not officially supported.

There are no hardware wallets that support Sia at this time.

Do not deposit funds into Sia wallets from any other sources. No other wallet is officially supported, and there are several fake wallets that steal user funds.

For any exchange related issue, please contact the exchange you are trading on before posting here!

Exchanges occasionally experience technical issues with the Sia wallet, such as delayed or cancelled withdrawals. Always contact the exchange first in case of wallet issues. No one here can help you with your exchange account. Please note that many exchanges have long support queues and it may take a while to receive a response. If the exchange has provided you with a transaction ID, you can also try to paste that into a Sia Explorer for the status on your withdrawal.
