Networks not live yet
Correct. http://blog.viacoin.org/2014/07/14/network-launch-update.html
We are running the network but have not released the clients. This is the final stage of testing. Vialectrum network has been turned on, but since no-one has any coins yet, you can send anything. During this phase the block reward is set to zero. When we are ready to release, which looks to be soon, we'll set the zero block limit and then distribute the full node. Presale participants will see coins in their Vialectrum wallets before this happens however (shortly after the presale closes).
