-## gana
-
-we can not delete the gana submodul from the donau. We use the gana from the 
exchange for the error codes, but not for the signature codes.
-
-how to update gana:
-
-1. update gnu-taler-error-codes/registry.rec and 
gnu-taler-error-codes/taler_error_codes.rst (Donau error code (ec) 8600 - 8700.
-
-2. update gana in exchange
-   
-   ```bash
-   cd contrib/gana
-   git pull
-   checkout master
-   git add . # gana-bumb commit and push
-   # install exchange
-   ```
-
-## keys
-
-the keys route has two main tasks: 
-
-1. act as route and return requested keys
-
-2. sign for other routes! -> Other routes do not have access to the private 
keys!
-   
-   
-- We do not sort the keys therefore we don't need a heap. We can directly 
iterate over the donation unit map. 
-- krd_array can be deleted. Its already hashed ???
-- Put KeysResponseData into the main datastructure. It contains the etag (year 
in our case and version)
-
-## issue receipts
-
-We must ensure that the update the receipts to date of a charity and the 
receipt request are both saved in the database or thrown away. To do this, we 
need transactions. Its best practice to try a database insert 3 times to reduce 
the risk of serialization errors (if it has not worked after 3 times, the error 
is probably somewhere else).
-
-## uncrystify
-
-install uncrystify. If so you cant upload bad formated code. With uncrystify 
you can automatically format the code.

+# Meeting 29.03.2024
+
+## documentation
+
+The abstract/summary and the introduction with purpose/motivation of the 
thesis should be understandable for everyone. The rest should be understandable 
for a for a normal computer science bachelor graduate. The Abstract/Summary 
will be  interesting for ngos, foundations, tax offices that show interest in 
such a system.
+
+Michiel leenaars did agree to write a motivational foreword for our thesis. He 
had the initial idea for the DONAU project. -> Note him and the NLnet 
foundation in the acknowledgment.
+
+## upcoming meeting with tax office
+
+Short presentaion Short superficial presentation of the project 10 - 15 
minutes.
+
+Questions:
+
+- How big is the fraud? Is this a problem? How many donations were not 
recognized? What is being done about it?
+
+- How are donation receipts checked? How are larger donations checked?
+
+## issue receipts
+
+if adding the issue receipt request does not work, try jumping back to the 
function with goto. Attention clean up memory.
+
+The stored primary key hash of the issued receipts should be made from as much 
as possible -> the hash should be made from the budis, keys and the charity 
signature.
+
+## keys
+
+The cs and rs helper should have a additional row if the private key is lost 
or not.
+
+
+
+## Some thoughts
+
+An interesting attack on donau would be to smuggle in a false public key. This 
would allow the attacker to issue unlimited donation receipts.
