How is flux obtained?

Could you elaborate on the process of obtaining Flux? I'm particularly interested in understanding the technicalities behind it. Is Flux mined like other cryptocurrencies, or does it have a unique mechanism for its distribution? If mining is involved, what are the requirements for miners and what are the rewards for their efforts? Additionally, are there any other methods besides mining to acquire Flux, such as purchasing it on exchanges or through staking? I'd appreciate a detailed explanation of the various ways Flux can be obtained and the associated processes.
