Why should I trust my device to subspace?

Subspace reserves some space on your devices hard drive and installs a database program.  The database is like an excel spreadsheet and is used to store data needed to run apps.  Apps that use subspace will spread their data across multiple devices on the network.  These devices will then serve that data back to the app as needed.  This is one part of what a server in a data center does.

Data includes things likes text, numbers, or small files.  It could be a user profile, a blog article, or product data for an online store. If you do not wish to host random data, you may choose to host only your own or your friends data.

All data stored on the subspace network is encrypted with the private key of the data owner.  Only the data owner holds the private key.  Private keys are also used to create unforgeable digital signatures to verify the authenticity of the data.  In this way data can be stored amongst a group of users who do not have to trust each other, while ensuring the data will remain private and may not be tampered with.

No.  Android and iOS will not let apps share data unless you as the user explicitly give it permission to do so.  The subspace app does not ask you to share data with other apps.  Subspace can only read and write data from empty space that you give it access to.  This is backed by several industry standard cryptographic proofs and techniques that are built into the subspace protocol.

No.  The app can only access data stored on the subspace network.  Even if a hacker were able to gain access to your private subspace data, it would be useless to them, since all of the data is encrypted with your private key.  The only way a hacker can gain access to your private key is if you give it to them by sharing it over an non-secure channel like text or email.  

What kind of devices can use subspace?

You can install subspace on as many devices as you like.  Just understand that a large number of subspace devices could impact the performance of your home WiFi network.  You can also link multiple devices under the same account, through a master wallet.

Yes.  It is recommended that you install the subspace app on your primary phone (but not run it) so that you can manage all of your host devices from a single account.  Simply decline the usage contract step when the app loads and then scan the QR code for each host device to link the wallets together.

You could run subspace on your primary phone but it is not recommended.  In order to earn the full contract reward your device needs to have power and internet connectivity 24/7.  Doing this with your primary phone could impact your data plan and battery performance.

Not at this time, though we are working a subspace desktop app that runs on a Windows, Mac, and Linux computer.

At this time there is not a server implementation of subspace, but that could change in the future.  There would be no advantage to doing this since subspace balances the data between all devices on the network equally, so a server would not be able to store any more data than a phone or tablet.

Apps built with subspace can run in a web browser, mobile device, desktop application, or on a server.  No special browser or chrome plugin is required to make this work, just a single open-source javascript library.  

How do rewards work on the subspace network?

Subspace credits are digital tokens that are used as a medium of exchange on the subspace network.  Subspace application developers use credits to purchase storage contracts for their applications and these credits are distributed to the owners of host devices over the life of the contract.  Subspace credits are divisible up one billion times each, with the smallest unit being a quanta or ‘quant’ for short.  A quant is roughly equivalent to one byte of disk storage.

Subspace credits are not an imaginary or arbitrary store of value.  They are backed by the physical hardware that exists on the subspace network.  The total supply of subspace credits is proportional to the total number of devices and amount of storage that has been allocated.  Every time a new user installs the subspace app and agrees to a storage contract, new subspace credits are created and placed into the subspace reserve.  

Subspace credits are secured by the subspace wallet, which is built into the subspace mobile app.  You can think of the wallet like a bank account that you have complete control over.  When you install the app it generates a unique set of public and private keys.  These keys are used to sign and encrypt data you store on the network, and to send and accept subspace credits.  Your public key can safely be shared with anyone, but your private key is only stored on the device and should never be shared with anyone.  Your private key is a very long set of random characters and letters that is practically impossible to guess.  The private key acts like a pin number for a debit card, without you cannot authorize any transactions for the wallet. 

The easiest way to get subspace credits is to install the subspace app on a device and earn credits for hosting data.  Early users of the app will also receive an initial reward of subspace credits, based on their cohort.  As subspace credits are created by new hosts they are held in reserve in the subspace vault.  Users or app developers who need credits for storage contracts can exchange US dollars for subspace credits from the vault, on the subspace exchange, run by the subspace consortium.  Subspace credits may also be freely exchanged between any user or developer who has a subspace wallet. 

No.  Subspace is a protocol for running decentralized applications.  It is more similar to something like BitTorrent, DAT, SSB, or IPFS, which are just new and improved versions of programs like Napster, Kazza, and Morpheus.  Part of the protocol includes a ledger that is used to track the balance of credits for all participants on the network.  Credits are not meant to be used as an everday currency (like US Dollars) or a speculative store of value (like financial instruments).  Instead they are a token or digital coupon that can be used for very specific purpose, to store data on the subspace network

The storage rate for subspace varies based on the total amount of storage on the network and how much is available at any given time.  In other words, the cost of storage is based on supply and demand.  Initially one subspace credit will be equivalent to 1 GB / month of storage and convert to .25 USD per credit.  At this rate, a storage contract for 128 GB of data over one month would return 128 credits by the end of the month, which would be worth $32 USD.  The minimum storage contract of 10 GB of data would yield 10 credits or $2.50 over the course of a month.  While subspace credits do have real world value and may be exchanged for USD, it is better to think of them as tokens that allow you securely store your own personal data.

Subspace credits are used to reserve storage contracts on the subspace network.  This allows developers to power their applications and users to own their data.  For example, instead of paying $10 a month for Google Drive, you can spend 10 credits a month to store your data on the network.  Subspace credits may be exchanged for USD or crypto-currencies on the subspace exchange.  You may also use the subspace wallet to send and receive credits to anyone on the network who has a wallet.

No.  We plan to bootstrap the subspace network at a natural pace in step with the needs of our users and app developers.  We have no intention to artificially increase the price through speculation or create tokens out of thin air that are not backed by anything.

What are the costs of using subspace?

Very little, but It depends on what kind of device you have.  The average smartphone will consume 3 to 5 watts of electricity when plugged in.  This comes out to around 3 kilowatt-hours per month.  The average cost per kilowatt-hour in the United States is 15 cents.  So it would cost you less than 75 cents a month to leave your smartphone plugged in all the time. 

Subspace does use your phones resources continuously, so it will impact battery life.  How much depends on how many network requests it receives.  It is not recommended to run subspace on a device for long periods of time (greater than four hours) that is not plugged in.

It depends on your usage contract, but not by default.  Some users may choose to install subspace on their primary phone and use cellular data if they have an unlimited data plan, though this is not recommended.  The default contract will only run the app when connected over WiFi.

No, it is absolutely free.  In fact, you will get paid in for hosting data on the network.  As long your device stays connected throughout the life of the storage contract, you will receive the full contract reward for being a host.  Service disruptions which degrade the performance of the network will result in partial contract rewards, proportional to the amount of downtime.
