I might try building this sometime soon. I think it may also serve an
educational purpose when trying to understand the whole network's behaviour.
What level of accuracy are we looking for though? Obviously we need to
fully emulate the steps of the network protocol, and we need to be able to
specify time taken for transmission/processing for each node. Do we care
about the actual contents of the messages (to be able to simulate double
spend attempts, invalid transactions and blocks, SPV node communication),
and their validation (actual signatures and proof of work)?
I imagine the latter is pretty useless, beyond specifying that the
signature/proof of work is valid/invalid.
If we could build up a set of experiments we'd like to run on it, it would
help clarify what's needed.
Off the top of my head:
- Peter Todd's miner strategy of sending blocks to only 51% of the
hashpower.
- Various network split conditions, and how aware of the split nodes would
be (and the effect of client variability).
- Testing the feasability of network race double spends, or Finney attacks.
- Various network partition scenarios.
- Tricking SPV nodes.
