 Today's demo from my side would be really fast because I just want to announce that we have a first draft of the hierarchical consensus spec. As you may know from previous demo days, we've finished with the first MVP of the protocol. We kind of know now what are the details and the basic end-to-end implementation of the protocol and we are working on having an alternative implementation in Rust leveraging the forest client. So we are exploring that line of work because right now everything is so HC is implemented in a fork of Lotus in Eudico and we're exploring having an alternative implementation and that's why we started this line of work of having a first draft spec. So if you go here, you'll see the description of the architecture, how all of the sub-protocols work like the checkpointing protocol, how cross-net transactions are propagated and all of the low-level models as well as some future work, like for instance, the detectable misbehavior or how collateral and slashing work. The idea is to have soon a draft of a fit that we can start discussing with the community but in the meantime, if anyone wants to read the spec, start using the MVP implementation or even like give us feedback, you see something that it doesn't make sense at all. Feel free to open a PR here in the protocol consensus lab. I don't know if to share it here in Zoom or maybe in Slack but yeah, so feel free to give us feedback right now. This just suffered a first internal review by the members of consensus lab but we are starting to spread this so that anyone can give us feedback. And I guess that's all from my side. Thank you very much. And if you have like any questions, feel free to ping me.
