Validate _multiple_ *publishers* (aka. producers) and _multiple_ *consumers* working on the same queue, exchange messages via some AMQP message broker without any message corruption. Messages consumed should only be consumed *once*; In other words, no consumer should receive a message that has already been seen by another consumer (it's in question if this will by technically proven).
* Out of scope: [Performance](https://en.wikipedia.org/wiki/Performance_indicator) data
* Algorithm used to prove correct message exchange: Similar to many blockchains, a (simplistic) [PoW](https://en.wikipedia.org/wiki/Proof-of-work_system)
### Producer
Generate hash over the last produced PoW, last produced proof and new proof, where proof is a prime number (to further increase complexity and unpredictability, this is a random number (between fixed MIN/MAX, however, the resulting prime can be larger than MAX) and the hash starts with n number of 0s (zeros).
