your concept is very similar to Nano with the concept of dPOS (zero fees and almost instant transaction)
even the name of your project is very similar to the name of Nano before rebrand Raiblocks (just rai)
im just sayin no offense because many parts are very similar to Nano
but based on the Rays whitepaper, it looks like Rays uses Blockchain not DAG like Nano
i became interested in seeing future Rays developments
