Many of these values are shared not just by many in the Ethereum community, but also by other blockchain communities, and even non-blockchain decentralization communities, though each community has its own unique combination of these values and how much each one is emphasized.

Open global participation: anyone in the world should be able to participate as a user, observer or developer, on a maximally equal footing. Participation should be permissionless.

Decentralization: minimize the dependence of an application on any one single actor. In particular, an application should continue working even if its core developers disappear forever.

Censorship resistance: centralized actors should not have the power to interfere with any given user's or application's ability to operate. Concerns around bad actors should be addressed at higher layers of the stack.

Auditability: anyone should be able to validate an application's logic and its ongoing operation (eg. by running a full node) to make sure that it is operating according to the rules that its developers claim it is.

Credible neutrality: base-layer infrastructure should be neutral, and in such a way that anyone can see that it is neutral even if they do not already trust the developers.

Building tools, not empires. Empires try to capture and trap the user inside a walled garden; tools do their task but otherwise interoperate with a wider open ecosystem.

Cooperative mindset: even while competing, projects within the ecosystem cooperate on shared software libraries, research, security, community building and other areas that are commonly valuable to them. Projects try to be positive-sum, both with each other and with the wider world.
