No testnet this week, working towards that though asap. Data chains option B is the focus right now in terms of the simulations and working out any remaining wrinkles in that proposal. Option A has a few lingering issues in terms of speed and potential attacks. We spent over 10 weeks in option A variants and option B is now getting a lot of focus to pull it apart if we can. Simulations so far looking good and I hope we can take a lot of that work to aid production code if possible.
