The Enterprise Ethereum Alliance (EEA) is a nonprofit working group whose aim is to define an open, standards-based architecture for business and enterprise use of Ethereum. Group members include many large companies from the world of software and finance, such as Microsoft, Accenture, and J.P.Morgan. The group is currently working toward defining the Ethereum Enterprise Architecture Stack, which itself will help guide the development of the EEA's overall standards-based specification.
EEA's specification will help define a standard way in which Ethereum's blockchain can be used for business purposes. However, given the opensource nature of Ethereum's codebase, adhering to EEA's specification won't necessarily be required: Ethereum's codebase can be used in any way desired.
