| Summary | 0003764: wallet needs to support /refresh operations to ensure unlinkability | ||||
| Description | When coins are partially spent, the residual value needs to be refreshed to ensure unlinkability. The wallet must thus automatically contact the mint and ask for a refresh. For this, the wallet needs to determine which denomination keys should be generated during the refresh, submit the commitment and perform the reveal operation. Keeping the intermediate state of a refresh operation in the database (so as to be able to resume nicely even in the case of a crash) is part of this report. Melting multiple old coins in one refresh operation is NOT part of this feature (this may be a feature of the protocol, but an insecure one and we should certainly not support this in the first iteration). | ||||

Implemented as of 78ea2ba5b1. We do resume from DB. The only thing not implemented is prompting the user for refresh or other options on payment failure, this is tracked by 0004735. |
