We've been doing initial network and transaction tests and the results are promising, we've hit our target transaction speeds of 1750 tx/s and look to test more on an even higher stress test. Our implementation of privacy via the sub-currency and zkSNARKs has also proven to obfuscate well and is doing what we hoped.
We plan on having a testnet in mid-February for the select individuals to test and get a feel for it, we'll have more details on this soon.
