Hi there!<p>In the first release&#x2F;MVP stage AKASHA will resemble a lot to Twitter&#x2F;Medium in this regard, in the sense that your published entries will be public and visible by everyone.<p>That being said, access control is on our roadmap but it is not a priority at the moment.<p>The updates are broadcasted via the Ethereum network through a smart contract that records and dispatches events associated with profiles such as new entries.<p>This way, the people that follow you on AKASHA will receive in their stream a notification letting them know that a new entry has been published and can be accessed via IPFS at hash X.
