Proof of Work vs sFUEL
There are a number of key uses cases that can use or even require Proof of Work.
One of the most important components of any application is onboarding. Proof of Work enables applications to remove the need to purchase gas entirely by allowing transactions to be sent without a gas token. Meaning that a PoW script can be ran once with the sole purpose of attaining sFUEL. Upon distribution, the user can utilize the application.
|Proof of Work does not currently work with Metamask. An anonymous (or random) signer should be used. This opens up the door for invisible onboarding as no clicks are required by the user.|
sFUEL should be used for most actions related to speed. As the Proof of Work method requires computationally intensive work, it is not always immediate. sFUEL should be used as much as possible to enable seamless user experiences.
