 ## Core R&D
 
-The discussion, resources and all research and development on the core protocol is fully open, free and public. Anyone can learn about it (as you are probably doing in this wiki) and further more, anyone can participate. There is no set of individuals which could push core protocol changes, the Ethereum community can raise the voice to help steer the discussion. To learn more about the core R&D shaping the protocol, read the [wiki page about it](/wiki/dev/core-development.md).

 ## Roadmap overview 
 
 While there is not a single roadmap that Ethereum development follows, we can track the current R&D efforts to map what changes are happening and might happen in the future. 
 A popular overview mapping many domains of the current core research and development is Vitalik's chart (December 2023):
