 ## Running
 
-To start a server that runs the KarmaCoin blockchain node and provides the KarmaCoin API and verifier API, create a config file `verifier.yaml` with the authentication tokens for the service providers used by the verifier, and provide the path to the config file to the server app.

 ### Xactor Usage 
 Xactor (unlike Actix) gives us nice and clean async syntax for actor messages. However, be aware that calling an actor message from the body of the same actor's message handler, will deadlock. It is easy to spend hours on such bugs. Just factor out impl into an async fn and call it from different message handlers....
 
-### Architecture
-- Uses `xactors` (over `tokio` runtime) actors pattern. Async actors that can return responses to messages.
-- Network protocols are defined in `protobufs` language.
-- Uses `tonic` and `prost` for grpc api services.
-- Xactor used as local lib - enhanced with new features that required low-level integration such as pub/sub.
-- High-level system components are all `xactor services` - registered in the system and restarted automatically when called after they crash.
-- Store is implemented using `rocksdb`.
-
 ### Code Structure
 - `base` - shared types.
 - `crypto` - low-level crypto lib.
-- `client` - Simple client with a grpc api for code reuse in testing servers and client-to-client p2p flows.
-- `client-app` - Simple terminal client app with support to config file, cli flags and logging.
-- `db` - Adds ttl capabilities to rocksdb data stoe.
 - `server` - Server implementation.
 - `server-app` - Simple console server app.
