Discussing whisper for matching askers with lenders

We currently match askers and lenders via on chain transactions like this:

-> Asker initiates a lending request via the ask method on the Base Contract

This may or may not result in a successful lending request (a call of the lend method by a lender). More often than not a transaction will be wasted and transaction fees are payed for nothing.

Now whisper comes into play. With whisper we can implement off chain matching of askers and lenders, resulting in only persisting lending requests for which a willing lender already exists.

How this is feasible and really useful for us longterm is to be discussed here, focussing on the workflow here in detail. Also a proof of concept learning the pros and cons of doing lending via whisper should be on our roadmap
