# VDE - Dark Energy Dark Energy is the fee tender for every transaction powered by Fractal. One Dark Energy Unit is equivalent to $0.10. Dark Energy falls in the category of a cryptocurrency instead of a digital asset because it only carries a balance. Dark Matter is a fungible digital asset with full provenance and all protections provided by Fractal. Dark Matter serves as a store of value that will increase in value. Everyone knows Einstein's famous equation regarding the relationship between matter and energy. The Transference of Energy states that matter can be converted into energy and energy can be converted into matter. Dark Energy converts and materializes into Dark Matter. Transaction fees are tendered in Dark Energy. Dark Energy is converted to Dark Matter and then Hive Workers receive Dark Matter as payment for their services processing transactions. Energy permeates everything and is generally intangible, like trying to pin down an electron. It needs to transform into matter in order to have a persisted state. Dark Energy is effectively a cryptocurrency in the sense that it only carries a balance and does not have individual unique data objects. It only serves one purpose, which is an implementation of IFeeTender for processing transactions in Fractal. There's more to it, but that's a start. ##### Relevant Tags > #vfn-token
