What is SpaceFuel?

Popular Questions

SpaceFuel is Space's native, asset-backed, mutual-credit currency.

SpaceFuel is a Spacechain-based currency that is a contractual service obligation, redeemable for hosting. SpaceFuel is a mutual-credit accounting system capable of performing billions of daily microtransactions. Its primary use is for Spacechain application (hApp) providers to pay Space hosts for their services.

SpaceFuel benefits:

• A completely peer-to-peer cryptocurrency.
• Optimized for high speed and minimal fees.
• Currency you earn for hosting on Space, and redeem to pay your bills.
• Completely accountable and transparent crypto-accounting, operating by known and shared rules running on every host machine.

How is SpaceFuel different?

• Mutual Credit: Unlike other cryptocurrencies which are primarily used for speculation, SpaceFuel is not tokens created from nothing. It is a double-entry crypto-accounting framework in which units are created, transferred, or destroyed at transaction time.
• Asset-Backed: SpaceFuel is backed by the computing power of hosts like you across the globe. That means it can be redeemed for a product with real utility.
• Value-Stable: The value of SpaceFuel is connected to the computing capacity of the network of hosts. This capacity evolves and changes slowly and isn't subject to huge spikes and crashes the way other speculative tokens are.
• Scalable: SpaceFuel is designed for micro-transactions, which means it needs to support millions of global value exchanges per second at fractional values. This is possible thanks to Spacechain's massively parallel design.

How can I use SpaceFuel?

• Spend it through a variety of apps and online marketplaces.
• Redeem fuel earned by hosting for other currencies to pay your bills.
• Borrow it, based on your proven hosting track record, to pay for things.

SpaceFuel marks the beginning of a new era of cryptocurrencies backed by the capacity provided by people. All of the currency supply is correlated to building and providing the computing power of the Space network. We always create that value together.

Most cryptocurrencies are modeled as digital objects tracked on a global ledger. With SpaceFuel, each user has their own ledger showing their account balance and transaction history. Each transaction requires an agreement between two people, which is then recorded on their respective ledgers and validated by peers in the network.

Mutual credit means that every credit (positive) has an equally matching debit (negative), giving a net supply of zero and a dynamic circulating supply that’s responsive to the actual market behavior of its users.

Credit limits are directly connected to a demonstrated capacity to repay a negative balance by providing hosting resources. SpaceFuel is directly redeemable for hosting services. SpaceFuel is therefore backed by computing power, a valuable modern asset.

Being asset-backed and having a dynamic supply means that SpaceFuel can be value-stable without being static or requiring a peg. SpaceFuel can optimize the market value of its units in relation to the cost of hosting, creating a steady and stable trajectory.

The agent-centric design allows for the transactions per second (TPS) to increase the more people use it, mirroring how the English language’s “words per second” increases as more people speak it. Therefore, SpaceFuel is scalable for mass adoption.

There is no mining or staking involved in earning SpaceFuel—only the useful work of web hosting. Anyone can become a host and be compensated by application providers who want their hApp served to the web.
