-
-The activity pub defines a server-to-server federation protocol to share information between decentralized instances and will be the main komponent for the gradido community federation.
-
-At first we asume a *gradido community* as an *ActivityPub user*. A user is represented by "*actors*" via the users's accounts on servers. User's accounts on different servers corrsponds to different actors, which means community accounts on different servers corrsponds to different communities.

-
-* inbox: to get messages from the world
-* outbox: to send messages to others
-
-and are simple endpoints or just URLs, which are described in the *ActivityStream* of each *ActivityPub community*.

-### Open Decision:
-
-It has to be decided, if the Federation will work with an internal or with external ActivityPub-Server, as shown in the picture below:
-
-![FederationActivityPub](./image/FederationActivityPub.png " ")
-
-The Variant A with an internal server contains the benefit to be as independent as possible from third party service providers and will not cause additional hosting costs. But this solution will cause the additional efforts of impementing an ActivityPub-Server in the gradido application and the responsibility for this component.
-
-The Varaint B with an external server contains the benefit to reduce the implementation efforts and the responsibility for an own ActivitPub-Server. But it will cause an additional dependency to a third party service provider and the growing hosting costs.

+### Overview of Federation-Handshake
 
 At first the following diagramm gives an overview of the three stages and shows the handshake between an existing community-A and a new created community-B including the data exchange for buildup such a federated, authenticated and autorized relationship.
 
 ![FederationHyperSwarm.png](./image/FederationHyperSwarm.png)
 
+### Technical Architecture
+
+The previous described handshake will be done by several technical modules of the gradido system. The following picture gives an overview about the modules and how the communicate with each other.
+
+![img](./image/TechnicalOverview_V1-19.svg)
+
+As soon as a Gradido Community is up and running the DHT-Modul first writes the home-community-entries in the database and starts with the federation via HyperSwarm. Each community, which is configured with the configuration key GRADIDO_HUB to listen on the correct topic of the DHT will be part of the Gradido-Net-Federation. That means each DHT-Modul of each community will receive the publicKey of all connected communities. The DHT-Modul will open for each received publicKey a communication-socket with the associated community DHT-Modul. Over this open socket the connected communities exchange the data "api-version" and "url" for later direct communication between both communities. The exchanged api-version info and urls will be written in the own database.
+
+The background of this exchanged data base on the supported api-versions a community will support with its own federation-modules. Each running federation-module in a community will support exact one graphql api-version of a cross-community-communication. To reach a dedicated federation-module with the correct api-version during a cross-community-communication the url for this federation-module must be known by both communities. As shown in the picture above the graphql-client with api-version V1_0 in the left community will interact with the federation-module with api-version V1_0 on the right community. During the lifecycle of the gradido-application it will be necessary to extent the features and interfaces for the cross-community-communication. To keep a backwards compatibilty and not to force each community to always upgrade their running software version on the last api-version at the same time, it will be necessary to support several api-versions in parallel. The different running api-version modules are responsible to convert and treat the exchanged data in a correct way to ensure konsistent data in the local database of the community.
+
+The up and running Backend-Module contains a validation logic to verify the community entries from the own DHT-Module. For each announced but unverified community-entry the GraphQL-Client is used to invoke a getPublicKey-Request. Depending on the containing api-version the matching GraphQL-Client is used and the getPublicKey-Request will be send to the given URL.
+
+As soon as the federation-module of the associated community received the getPublicKey-request the own publicKey is read from database and send back in the response.
+
+The GraphQL-Client will read the publicKey of the other community from the returned response data and compare it with the data of the community-entry, which caused the getPublicKey-Request. If they match the community-entry will be updated by inserting the current timestamp in the verifiedAt-field of this community-entry.
+
+This federation and verification logic will work the whole time and can be monitored by observing the communities-table changes. The Admin-UI will contain a Page to have a look on the current state of the communities table content.
