There is a whitepaper https://bismuth.cz/whitepaper.pdf with a primer on Hypernodes - Far from Dash Masternodes. I'd like to see precisely what is supposed to be "copied" from them.
Native Tokens are a core feature of Bismuth and not a clone of ETH tokens. Bismuth execution model is also very, very different from Eth. The "Hack with Bis" repository https://github.com/bismuthfoundation/Hack-with-BIS gives more insight on that subject.
Like explained in the release post - for those actually reading our announces - HYFI is a native token on Bis chain, rewarding owners of Hypernodes - in addition of the main BIS reward. It has nothing to do with scammy DeFi tokens on ETH chain. It's the basis of a fidelity program.
