### Interop Layer engineering plan

#### Smartcontracts for aggregation layer (Jesus)

* Working on it, expected by 15th dec.
* Audit pending. We don't know if we can include this at the end of the current sigp audit or we need to run a new audit only for this

#### Circtuis for the aggregation layer (Roger)

* Done. Testing phase
 
#### New aggregator ( CDK Team? )

* Pending to start

As Jordi described we're going to have new stages that would happen before the final aggregation. For that we need to modify our current aggregator and/or create a new aggregator for the new stages. We would need also a new GPRC to communicate all the componentes.

#### New proverc for aggregation

* Pending to start

We need to adapt our current prover to make it compatible with the new circuits and also make some simplifications in order to reduce the memory requierments of it. We also need a new GPRC compatible with the new aggregator.

#### Stateless proverc

* Pending to start 

Is expected by the end of the year, it consists of being able to generate proofs without direct connection to the database, passing all the necessary elements from the database to the prover.
