 Okay, so this is about the Filecoin Lightweight to Chain Snapshots. The project abstract is produced Lightweight Snapshots, which are required by new Filecoin nodes to join Filecoin networks in less than 24 hours. It would take weeks or months to sync a new node from Genesis on main network, that was Snapshots. Snapshots are the critical part of the Filecoin ecosystem, so this is an adoption project aimed to provide guarantees by operating a HA fault tolerant service, monitoring and commit to service levels. The Snapshot service should be capable of producing Snapshots from DevNets and TechNets as well to support rapid node bootstrapping and test environments, and this project is led by Travis Perlton. Riva has been running a Snapshot service since the start of mainnet, and the outputs of our first milestone will be in line with that service, which we will produce a latest Snapshot and timestamped files stored in F3, and the NetOps service will take over for results. Our goals are to guarantee Snapshots are never older than four hours. In the meantime, to sync a Lotus node from Snapshots should be less than two hours. There should be redundancy in the Snapshot service and storage and distribution of Snapshots, and we will be reproducing Snapshots as they are currently produced and we will make sure there is monitoring and alerts for the Snapshots with runbooks. A quick overview of how we're doing it. Travis wrote the PowerPoint chain archiver service, which has a node locker service and a exporter. We're leveraging the Kubernetes cron jobs and using open source home charts that we've authored and just using Lotus. A quick overview is just that we're able to run concurrent Snapshots and guarantee that each Lotus node is only running one Snapshot at a time to avoid complications. Our progress so far, the work is done and we are now actually producing Snapshots on calibration and mainnet. If you're going to check out those Snapshots and test them, there are some links here and to get to our M1 soft launch goal, we need to complete the validation and learning and runbooks. The M1 soft launch is scheduled for July 20th. At that point, it will be for experimental use and testing and Rebus service would continue to run. M2 would be our production launch, which would be the end of Q3 2022. We'll work on increasing our confidence in those Snapshots and their correctness by having continuous validation running and improving alerting documentation and runbooks. At that point, we hope that Rebus service could begin to sunset and we'll need to coordinate with the Thoughtpoint Dev team and then as well make sure we do a lot of comms in coordination with the broader network is the Snapshot links are probably baked into a number of two links out there. I'm leaving the best for the end here. You're probably wondering of all your storing Snapshots in S3. We should be storing it in our PL Web 3 stack, which we are definitely thinking about and I want to highlight some of the challenges around this. So the Snapshots are a little under 80 gigabytes in size and are produced every two hours. So that's one terabyte of data a day. And we also expect the size to increase. So we're talking about a fairly large scale storage system to support this. And then Snapshots become less useful with time. So one feature we would like to see here is a retention period to keep our storage scale down and also to keep cost down. And I think the most important part is we have some fairly some tight goals and service levels about being able to ensure that Lotus nodes are able to bootstrap as quickly as possible. So we need to make sure that any solution that we actually land on is able to support the download throughput that will satisfy our goals. So this actually makes the Snapshot service a fairly good case study. And we are going to be checking if Kubo and Cluster would be able to satisfy those goals with benchmarking. And there's a whole list of cool tools that have come out in services that we also plan to test out. And we would love your feedback and input on this problem. And you can join us on Phil Infra and Phil Slack. And we would love to hear some of your proposals on how we could search Snapshots with our PL WebTree stack. That's the end. Thank you.
