## Event Driven
* Plug para validar minter signature
* Estructuras de los eventos.
* Crear el EventManager para convertir las respuestas de la base de datos a eventos.
* Layer de "Core" con las funciones.
* Crear account en base de datos y crear registro de BlockchainTx.
```elixir
def create_account(changes) do
changes
|> Accounts.create()
|> handle_response() # To create the BlockchainTx if the response is successful
end
```
* Crear asset en base de datos y crear registro de BlockchainTx.
* Crear payment en base de datos y crear registro de BlockchainTx.
* Autorizar asset en base de datos (WalletAsset) y crear registro de BlockchainTx.
* Crear el Nofitier en una migracion para el BlockchainTx.
* Modificar el listener para manejar los diferentes eventos.
