View Agenda →// What are Core Developer Calls?
CDCs are public meetings where ETC client developers coordinate protocol changes. Every network fork — from Frontier (2015) through Olympia — is discussed, debated, and finalized through this process. Rejected proposals (ECIP-1049, 1051, 1098) are also documented here.
