## Call Summary

There were clearly two groups of people in the call: Solution Developers and Core Developers.
_SolutionDevs_ are using Whisper and Whisper-Clients in their solution for corporate customers.
_CoreDevs_ are developing technology (both protocol an client).

Most of communication in the call was between these two groups.

#### Chatham House Rules
I would ask all participants to apply [Chatham House Rule](https://www.chathamhouse.org/chatham-house-rule) to all _WhiSpeG_ meetings. This is in respect to all Whisper Devs, who would not like to be exposed in public too much.

## Discussed Topics

### 1. Specification
_CoreDevs:_
Considering current state of specification as quite solid.
If SolutionDevs need better specs, they should create a PR or an Issues on specs. What is not good enough exactly?

More resources (technnical writers) to improve Specs would be appreciated.

_SolutionDevs:_
What is the current official specs that being maintained? Unclear.
It would be nice to have a spec of a quality of a good IETF level.

Looks like we are missing single source of true for Whisper spec.

### 2. Testnet

_SolutionDevs:_
Is there any testnet? We just don't know any.

_CoreDevs:_
There is a testnet. We will publish inode's addresses.

### 3. UseCases
_CoreDevs:_
ask about detailed UseCase descriptions from SolutionDevs. Whisper (like other IM protocol) has different aspects:
* P2P,
* Darkness (conversational and metadata),
* Throughput,
* Reliability.

Which of them are more important for which UseCase?

_SolutionDevs:_
UseCase descriptions can be provided.

### 4. Benchmarking and Comparison
_CoreDevs:_
UseCases provided by SolutionDevs should contains quantitative requirements.
It is hard to solve trade-offs correctly while developing protocols without quantitative requirements to be met.

There is a swarm toolset to benchmark a network. May be it could be applied to Whisper development too.

Different existing IM protocols should be evaluated and compared to each other. It helps to set better development goals.

[@Ethernian](https://ethereum-magicians.org/u/ethernian):
Comparison and Benchmarking can be carried out as part of [Comparative Studies](https://github.com/Ring-of-Ethereum-Architects/knowledge/blob/master/base/ComparativeStudies) made by [Ring of Ethereum Architects](https://github.com/Ring-of-Ethereum-Architects/knowledge) .

### 5. Miscellaneous
Meetings biweekly proposed.

[@Ethernian](https://ethereum-magicians.org/u/ethernian) will create a poll to move existing chat group from telegram to somewhere.
