-The roadmap is mostly the result of years of work by researchers and developers - because the protocol is very technical - but any motivated person can participate. Ideas usually start off as discussions on a forum such as [ethresear.ch](https://github.com/ethereum/ethereum-org-website/blob/1c5502a0abaa746512323bbce0fbf1093387a724/src/content/roadmap/ethresear.ch), [Ethereum magicians](https://www.figma.com/exit?url=https%3A%2F%2Fethereum-magicians.org%2F) or the Eth R&D discord server. They may be responses to new vulnerabilities that are discovered, suggestions from organizations working in the application layer (such as dapps and exchanges) or from known frictions for end users (such as costs or transaction speeds). When these ideas mature, they can be proposed as [Ethereum Improvement Proposals](https://eips.ethereum.org/). This is all done in public so that anyone from the community can weigh in at any time.
