Hi. In October, I announced that our government would be conducting a review of the Professional Reliance Model. Under this model, qualified professionals, licensed biologists, registered foresters, technicians, engineers, conduct oversight of companies both in the planning stages of projects and the operation of them to ensure that provincial laws and regulations are followed. They effectively oversee the public interest on our behalf. It's important that the public is assured that there's proper government oversight and that all of these systems are working well to ensure that the public's environmental, safety and other interests are maintained. We're consulting with stakeholders, we're consulting with the societies themselves that govern these professionals, and we're looking for input from the public. So I thank you in advance for your participation in this review through this website.


stuff's worth some money for a long time before that one time. Now this is not a very long one because somebody taking all this this wood out.  Just come in and get what they want to probably do it at night.  Guessing this is uh the washroom. Really cool. So there's another one for you. I'll see if I can get a picture of the front. I'll walk around the front and see how grown up it is. Monkey and Bruno waiting on us. We're wanting to come here to check there's a window I kind of pointed out of. Guys but I mean there's not really much interesting there. I'm going to get some more abandoned places. Oh starting me on YouTube was abandoned houses and abandoned structures so I need to get back into that keep with my roots you know of my YouTube channel and still keep you know doing the other stuff that way. I don't want to open up another channel because I wanted to be all under one channel that way there's something for everybody.

Hi, I'm Dr. Olyth Selvan, Consulant Heptologist and Chairman of Division of Liver Transplantation, Manipal Hospital's Bangalore. It's very important to screen pregnant mothers for hepatitis B because that can be easily prevented in the newborn child. You have to check for HBSAG, which is blood test, which is specific for hepatitis B, and then find if the mother has got active infection. If the mother has got active infection, she needs to be given medications to decrease the virus in the blood. And also the newborn child has to be given both active and passive immunization to prevent HB infection for the kid.


Welcome to my journey to 10,000 YouTube subscribers. Hello, I don't really know how to do interest for the series out because usually for vlogs, I do like a montage of what's happening in the video and for these it's like, camera on, let's go. But anyway, my cat is not happy with me talking to you guys right now. He's like walking away. Oh, he's so cute. Now he's scratching my tongue with it. Anyways, hi, my name is Nika. If you're new here, please make sure you subscribe. I'm currently on a journey to 10,000 YouTube subscribers and this is my February, March update. Wait, it's gonna be April. I guess this is my April update. I feel like March really flew by and I had so many ideas that I wanted to do but I didn't really do and you know, a lot was happening. So let's just get right into my analytics and then I can kind of tell you guys like kind of what was happening and going on for me. Let's get into it. Okay, so for the month of March, I got 8,837 views. I'm still like really excited about that even though it is less than February. February, I just had such a good month. But 8,000 is still a lot better than what I usually get. Usually I'm around like 4,000. So nearly twice of the numbers that I'm usually used to seeing and I'm at 129.9 watch time hours and then plus 39 subscribers which still like, usually I get like 30 subscribers a month. So I'm still very happy with those metrics. I think my numbers are going down because I was consistently posting two videos a week in January and February, like two long form videos. And this month I just haven't been able to do that because I've really, really, really been focusing on getting my apartment series kind of ready. And so that's just been me editing a lot but then not posting it. So I've been posting basically one video a month or a week from March, except for this week. I'll post two videos because I'm gonna post one today and then I'll post this one on Friday. But yeah, I have not been posting as many videos as I would like but I think it's gonna pay off in the end because my apartment series is coming and apartment videos always do really well on my channel. What else? So let's go to the monetization. So in terms of subscribers, I'm now at 584. I'm very happy with that. My goal I think was 600 or 610. Let me double check. 210 and then my watch time goal was 1170 and then my view goal was 100,000. That did not happen. But it's okay. Like when you're trying something new and growing a community, I think what social media is really beautiful about teaching is like, it's okay to fail. It's okay to not hit your goals but take a moment to look. You're still growing and you're always growing. Like I just hit 1,111 followers on Instagram and I'm really happy about that because it's like for a while I was stuck at like like under a thousand and then suddenly I just, you know, things kind of just started clicking. So I'm really happy with my growth even though I didn't meet my goals because I feel like I'm still, I'm still, you know making my way, making my way. I thought my goal was like 1,100. I was like, I could kind of still hit that, but it wasn't. So I did not meet my goal, but that's fine. I would have to put my views. 80,910, that's pretty good. Definitely not 100,000. Y'all, I was, I was really, really feeling my oats in February. Oh my God. I'm happy with the growth that I have. And I do think that next month, I'm not gonna say the apartment series is gonna come out next month because who knows? I've been working on that for so long, but I do, I finally saved enough money for an iPad. And so next month, one of my really big goals to learn and like kind of work, like how to make my thumbnails and procreate, which is honestly the reason why I'm getting an iPad and I'm really excited because generally my click-through rates on my video thumbnails are just low. And so I'm like, if I can make better quality thumbnails then everything else should start flowing, right? So right now I just use Canva to make my thumbnails and because Canva's so popular and they have all these YouTube like thumbnail templates, I just think I'm getting lost in the sauce. I think once I'm able to get procreate and then like literally just draw and make my own like illustrations and thumbnails and stuff like that, I will see a little bit of uptick there. But is there anything else I want to say? Oh, I have to make a new goal obviously. Also during the month of March, my SD card ran out of video like memory. So I had to wait a couple of days to get a new SD card in the mail. And so like things were just like not, it wasn't gonna happen for me. But I think it's fine because I honestly like, I feel like there could be a little bit of seasonality in YouTube and I honestly, I really think that my apartment series is gonna pay off. I'm like, I'm gonna bust it. But yeah, it's due in April. I do want to try that long form book video as well. I'm finished, stranger, stranger things. Oh my God, what is it called? Oh, I finished the silent pageant and now I'm doing the maidens, which is pretty good. But I also feel like I need to go back to like nice romance novels because it's taken me a long time to get through the maidens. But my goals for April, I think I wanna maybe keep the same goal and just do 110 subscribers, watch time, 100, 170 views, let's do 100,000. I honestly think it's possible now because I'm closer now than ever. So we'll see. Let me know if you guys like these types of videos. And then I'm also doing a series on TikTok. That's similar, just like my analytics for TikTok. And then I also, well, I don't really do it on Instagram because I don't think anyone cares on Instagram. But if you guys wanna see my Instagram, it's up to you. Please let me know in the comments below.  I actually need to meet with my academic advisor about it because it's honestly gonna be a project for school, but also for me and my like content creation business. So we'll see. I'm like, do I have anything else to say to you guys? Videos I wanna do. I still wanna do my long form book video. Still wanna get my apartment series out. Maybe I can do it in April, but I just don't wanna make any promises. I have, ooh, I have gotten like pretty decently. I added them, like the rough cut is done. I just need to pair them with music and then add like the captions and transitions and do an intro. So honestly, I should be able to finish like all four of them in April. We'll see. I really think it's gonna help my channel, but I don't even wanna launch them right away because I do wanna take some time to practice creating thumbnails with appropriate. Let me get my iPad. I'm rambling now, but I hope this was an entertaining video for you guys. My name is Nika. Make sure you subscribe. I make videos about like New York City life, graduate student life, all the above like spirituality, mindfulness, yoga. I am a yoga instructor. So thank you so, so much for watching. I love ya and make sure you subscribe. I'll see you in the next video.

Ooh, are those new balls? BC Fairies, is that new ball? They're fully electric, right? Oh, no, wait. Ah, yes. A planned plan. The most planning of plans.


front of Congress today. So I think it's going to be a wild day. So let's just try to do something and get out really quickly. Because the market's going to react to the Fed, but it's up this morning with NVIDIA. When we're done, we'll talk about NVIDIA. Really, really great call, you know, and I know, I know people killed it. So I just, it's something that some of you have to wrestle with, I think, and we can talk about the chart when we're done. If you're in the NVIDIA calls, I just let them run up. There's no new trades today. Okay, this is either not open or what? I don't have JWN open. So I guess we're going to Foot Locker. We got to make sure this is open. And I don't think this is open yet either. Hmm, interesting. Okay, flipping around here now to Foot Locker. But want to make sure this is open. And I just don't know. I just can't tell here. Okay, my clock is moving. I think my charts are okay. Can everybody hear me? There, now it's moving. I really want to do something new today, Jackie. I like these gaps. I do. I don't think this is open yet, though. This is just, I don't know. A, I don't know if it's open. And B, if it is, it just went all the way down to 29. Well, this is really strange. I guess it is open. It's already going. Oh, that is really weird. Didn't do it. Wasn't sure if it's open. Drop more than a dollar. There it goes. That's it. We didn't do it. I couldn't determine if it was open. So I'm flipping over to JWN. Oh, that was really weird. That's a kind of a shame. Okay, stopping this is going to be 1950. It's going to be wide. Let's do 50 by 50, JWN. Footlocker's done. It was open. It went. It fell. Didn't do it. It just looked too strange. 50 by 50. Let's do 60 by 50. JWN. Forget Footlocker. It's already gone. 60 by 50. Let's do 60 by 30. 60 by 30, JWN. Tighter. We had done that. We would have been done for the day. That was just really weird. I don't know. Did anybody do it? I couldn't determine if it was open. It wasn't moving. The volume was too thin. Maybe I was too cautious, but 60 is valid here. 60 by 30, JWN short. It was weird. Don't do this till it hits either. This is definitely open now, but we're going to get some today, I think. Do it. Do it right now. It's valid. 30 is the stop. Here we go. We're not going to miss this one. 18 and a break and a flush and we're out and we're done. The Fed's going to talk today. I have no idea what he says. He's probably going to not say anything new, but the market's going to react. So you can bet your booty on that and how it reacts. I don't know. Nor do I care. I'm not in the market. The market may not do anything actually until the Fed talks. They not do anything at all. All right. Where are we? This is definitely open now, but the trade went. All right. Here we are. We're in this. If you didn't do it, you could still do it. It stops 1930. It's really not bad. All we're trying to do is get it down for one push here and have a quick, fast morning and done. Didn't want to do any continuations today. Didn't want to do anything except that something was new. Thomas is in the Divinia Call. You can get out right here or you can wait. You've got to watch that. We'll talk about it when we're done. And there's nothing to discuss with the market because the market is going to wait until the Fed. Here we go. One more push through the number. Here we go and here we go. Here we go. JWN. JWN. JWN down. Here we go. JWN. Well, you should be in the target option, but I didn't want to day trade that today. Here we go. JWN. 1917. Penny by penny by penny. You can take it out right here if you want. Come on. Just go. Hand of the button here. JWN.  Here we go. Any second. Any second. Come on.  Good, good, good, good. More knee. And again, this probably still goes. Probably goes to 1775. Probably breaks. Probably keeps going. Excellent. Wonderful. Beautiful legs in here. Again, if you want to get it down, it's probably going to go to 17 something because I think it breaks 18. That was close enough. Again, don't want to suffer through a rally back. Here it goes. It's going to break 18. Is anyone still in it? I think I had a good exit here on this though. Here. Boo. There it goes. It's good. There. Boom. It just did it. Is anyone still in it? Anyone, anyone at all? Allison's out. It's going to try to break 90. It's going to try. Thomas is out. Gerard is out. I think I had a really good exit in that one bar. Not knowing where it could bounce.


If the first thing you notice about San Gregorio training area is the desolate terrain, dry heat and dust that gets everywhere, you're not alone. And that's the point.  This Spanish soldier is a four-time veteran of Afghanistan. If that weren't enough, he's on the unit bomb squad and he says he's had to diffuse his share of bad situations. Today he's got the attention of Spanish troops preparing for a possible upcoming deployment. He shares everything he can with them because this may be his one chance to train with them all year. The training is going on here is the Spanish are doing their annual engineer training event where they're bringing representatives from every engineering unit across their army. Brandon Cave is a U.S. Army major with the Joint Multinational Readiness Center and what these Spanish engineers are preparing for, he's seen up close. I'm here to observe the training events and then just make recommendations to them and how we can always make training better and just to kind of share TTPs with the Spanish and gain information and all of them as well. I find that you learn just as much from them every time you work with them as they learn from us. So it's always a privilege to work with them and it's always interesting what you learn. They've been over these drills more times than they can count because when the time comes they may only get one shot. It's better to learn here than learn in Afghanistan. Much as it resembles where they're headed, the desert here can only teach them so much. The rest they'll have to learn from each other. Just the future warfare and the next conflict I'm going to bet I'll have Spanish stand beside me, I'll have NATO members stand beside me and other members from ISAF will probably be right there with us. So it's just the future warfare in my mind. For U.S. Army Europe, Jesse Granger, San Gregoria training area, Spain.


So my beautiful people I am back with another outer ring video and today guys i bring you seven amazing weapons you don't want to miss. How's it going guys my name is DP Jane if you do enjoy the video leaving a like it really helps out and if you like what you see and want to see more be sure to subscribe and turn those notifications on so you never miss a video. Okay so today I bring you seven amazing weapons well six and a half weapons shall we say even so that that one and a half or that half even is incredible and you must get it okay so let's just get straight into it and the best thing about this is and the way i'm going to arrange these videos is i try and group these up so they're more or less in the exact same area so we ain't going from north to south to east to west going all over the place so you can in general grab all these while you're doing this so yes I hope you enjoy and let's get straight into it guys and start with the Lord Sworn Greatsword so this is probably the one that's out of the way kind of but not too drastic whatsoever so upon when you first enter the open world you want to come to the gate front ruins where you can see me out on the map right here now there are those uh great sites either side of these so you can trigger them while you're here as well but it is guys look more or less as simple as going behind this one wagon and simply taking out this dude this would be from the west side grace so yeah just come from there take out this dude and simply open up the chest guys and there you have it the Lord Sworn Greatsword and well it's as simple as that okay so from here on in we are actually traveling basically south from where we are right now we're going to end up at the bottom at the map but you want to grab all these while you're here if you haven't already so this weapon here right now we have the great api i believe that's pronounced i'm not even sure but it's a heavy thrusting sword and it looks absolutely incredible so you can see where i'm out on the map right here you just want to come to this simple spot now what i'll say is there are quite a few enemies here but you can basically kite them away so if you jump on your mount and do exactly what i do you should actually be free to actually just jump down and grab the chest so you'll see what i do actually run past them jump on top of this kind of like old building whatever it is or ruins i don't even know because the only dude here you want to really stress about is the guy on horseback that's it because with him and his big fat sword it just it just does serious damage so you can see i run past the so uh the chest so then i come up this way and what happens here is guys you can see the one the one guy on the horse so which is out you may as well grab this thing on top of the roof right here guys take this guy out too he's relatively straightforward to kill shouldn't do anything serious to you don't you take him out you grab this right here which is a royale scroll i'm not sure what that's for yet then simply guys just jump down and quickly grab the chest jump back on your mount and get the heck out of there but yeah guys it is as simple as that okay so now we're heading even further south guys and now we're going to get the morning star which is a hammer but it's a badass looking hammer like a ball with spikes on it on the end of a stick which you know just hurts so from the same actual grace we just went to the last weapon from he just went ahead south so from here guys just jump on your mount and follow the path i take to the bridge of sacrifice ignore all enemies just follow the path i do and it is as simple as that i catch you guys back in a quick second okay so once you get to the weeping peninsula did that say i'm not even sure um you'll come to the wagon you can see it right there in front of you now here you want to obviously crash walk you want to go to that stealth mode so you don't want to be picked up by any of these enemies especially that big old dirty troll under right there so what you want to do is guys just crash walk and you will have to take out one guard from behind but as soon as you kill him simply jump under back of the wagon and get that incredible looking morning star hammer okay so next up guys we have the hand blister which is another monster now the point we were just out on the map um the bridge of sacrifice just to the right hand side of it is a sight of grace which you will obviously want to trigger but it's slightly just right over the actual morning star uh but you'll see that on the screen now so from this point on the map guys just want to follow the exact route i take so pull out your mount and compass again the wagon the wagon which you actually picked up the morning star from so you should get the gist of where we're actually where that sight of grace is so compass this point guys and keep coming like not all these enemies run past them grab the shinies if you want i mean no one's going to hold it against you let's keep coming keep coming keep coming then you'll take a sharp right then what you'll have to do guys is you'll have to run up this hill take out a dude and his manky looking dog and then climb up this kind of mini tower now you will have to take out a couple of guards nothing too hard whatsoever but at the very top in that chest is it's incredible beastly hand blister so yes guys take that and enjoy it okay so next up guys we have two items just slightly further safe from the actual uh the morning star because after the morning star we went and got the hand blister now we actually took that sharp right remember now if you avoided that and come down more safe not too far you would eventually come to this grace point the castle mourn rampart and from here guys we want to make our way even further safe as you can see on the map right here now we want to enter this kind of like castley building thing but there's a massive dude standing right in front of it the ginormous baron arrow so you you'll actually see shots before you see him nine times out of ten so yeah be careful here obviously you want to avoid them as best as you can just do what i do on screen now and you should be all good though guys okay so once you get to this point people it's relatively straightforward uh you don't have to worry about the bow and arrow dude here i learned quite quickly that you can't actually shoot through here so you want to activate this um this grace not too which way is about that and from here just want to take the lift upwards and from here guys this way you have to sneak otherwise you will get attacked by a ton of enemies and you don't want that so just follow the path i take unscrew now sneak past all these dudes and eventually you will come to this room right here now just on your left behind these this wood is a chest in this chest guys is that incredible claymore sword you don't want to miss this you really don't and from this point guys we're going to grab this steel wire torch which is a upgraded torch but you can also like brief fire with it it is amazing as you'll see it on screen now so from the point of why we just got that claymore sword follow the path i take on screen now so you'll come down these steps and you want to run past these dudes guys and run straight up this ladder they will follow you up but that's all good then once you get to the top run across and jump up this ladder again and hopefully the enemies just take each other out and when there's just the same group of enemies left jump down and slay the rest of them and once you've jumped down and slayed the rest of them there's a couple of things you can collect here but the main thing guys you're being guarded by two more enemies which you will have to take out once you take these out people you are good to grab that incredible amazing steel wire torch you don't want to miss this okay so lastly people today and the seventh weapon and item for today's video is the whip now the whip is straightforward it's a whip it whips enemies it's as simple as that now to actually guide you to this one we're going to come back to that last grace we just went to and before we got the claymore and the steel wire torch so it's just literally the one at the start of this castle so come back to this guys and i'll show you the location to another grace and then to get the whip you will have to take out a couple of giant rats but they're not too hard whatsoever so come forward guys and pull the lift back down it's probably best just to if you did grab that claymore and the steel wire it's probably best just to flash travel back to this grace and just follow me follow the path i take because you do go a different direction which you get up toward the enemies are we have to sneak past them so yeah once you get to the top of the lift here guys get into that sneaky crouch mode and do what you got to do so here just come forward now you haven't got to be oh to be honest you could probably just run straight past these because you get to a point where you just jump away from them anyway so it doesn't really matter so you can see the mark the point on the map i just marked so yeah that's the way we're heading really so you can see i'm actually just looking around here because i know i know there's more secrets in this area i just i just haven't had time to explore up to my eyeballs people in videos to make and things to cover this certainly over so yeah you can see at the end here and watch this beard pumpkin head dude see the dog to start chasing me so yeah my couch stealthy walking uh didn't quite work there so i grabbed this smithing stone you'd probably want to grab that then you want to head this way like so just run past your ads run past the enemies don't even stress about them don't even stress about them and then guys you want to climb up this ladder be careful because they can't get you like that you can still chop your ass just get up here and go as fast as you can oh come on i'll wiggle him up okay so from hop here guys it's relatively straightforward where you gotta go so just follow where i go right here again avoiding all the enemies don't even stress about them don't worry about them and here guys again i think i do i grab something up here i'm pretty sure that i do i'm sure i do do i oh no no no just jump down real good that's what i do i grab the grace that's what we're doing this is the other grace instead you want to grab and from here it's relatively straightforward you just run and jump off the edge of this wall and just keep going down and following where i'm going uh don't worry you won't die you can grab this while you're here too that's the one sort of key you don't want to miss one of them you know they're very handy for opening certain pathways in dungeons and shit i'll grab that while you're here and then guys you just want to jump off this edge here onto the top of this building just run here guys just walk around it and just jump down here and then go this way here may as well in may as well just keep coming down just keep coming down eventually you'll get to this building here we have to drop for the top now you probably can grab these without fighting these rats um i just thought i'd just kill them just just to make it easier on myself i obviously want to use these beams because if you jump down from the top you're probably gonna die and let's jump down again and you'll see that they is in that corner right there so if you jump down you'll see it right at the back there there you go so i see i notice a rat clocks means like oh dinner so i take him out look cut your ones out and kill them let's run to the corner and grab it guys and it is as simple as that and that is the whip and how you get it people and there we have it guys for another video and i hope you enjoyed it if you did leave a like really helps out if you're new around here want to see more outland rings be sure to subscribe and hopefully people i will see you on that next one


Item No. SCP-4597 Object Class Euclid Special Containment Procedures SCP-4597 is contained within a standard humanoid containment cell. SCP-4597's hands are to be encased in fitted gloves filled with polymer gel No. MCN-119, refreshed daily. A plexiglass partition divides the cell between SCP-4597 and SCP-4597-A. Description SCP-4597 is a young human male suffering from dermatillomania. SCP-4597's skin possesses accelerated, if flawed, regenerative properties. Observation has shown that regeneration takes only a few minutes even when entire sheets of skin are torn away. However, due to this, large portions of SCP-4597's dermis are heavily scarred and discolored. Additionally, the dead cornea stratum lair is abnormally thick, ranging from 5 to 120 mm depending on location, with SCP-4597's lips, fingers, toes, and knees exhibiting the thickest layers. SCP-4597's dead skin is abnormally difficult to cut or pierce without the use of either metal tools, lasers, or SCP-4597's teeth or nails. It also becomes gradually thicker and more durable each time it heals. SCP-4597 partially circumvents this durability by exploiting weak points, such as ingrown hairs, new calluses, existing notches, or water softened areas in order to continue its self-destructive behaviors. The living dermis exhibits no unusual durability. Once removed from SCP-4597, the dead skin becomes animate. Dead fragments will wriggle before ultimately joining an existing sapient, a morphous pile of skin fragments in the shape of a large, currently 3 meters tall, dustmite with elongated limbs, classified SCP-4597-A, held together with dried blood or pus. During initial observation of SCP-4597 while sleeping, SCP-4597-A was seen using its mandibles to bite thinner areas of SCP-4597's skin, creating small notches and using rough edges of its skin portions to sharpen SCP-4597's fingernails. In response, current containment procedures were enacted. During separation from SCP-4597-A, SCP-4597 has exhibited signs of anxiety while its condition has slowed significantly, with large sections of skin beginning to heal and decrease in thickness. Conversely, SCP-4597-A has begun to act erratically, hitting itself against the partition repeatedly and peeling and chewing on parts of itself with its mandibles.


All right, so welcome everyone to the Schubert seminar before we start today's seminar. Let me remind you about the couple of announcements. The last seminar and there's announced that we are looking for nominations for either graduate students or for postdocs who are interested to give short talks. Short talks will happen probably at the end of November beginning of December and especially the early career people that are on the job market are encouraged to to nominate to be nominated. They can self nominate somebody else third party can nominate them and so on. So please, if you if you know anyone and that person is interested in giving a talk. Please send an email to any of us. And the next seminar is going to be next Monday at the same time with Dave Anderson. And now let's start today's seminar. So Chang Long Song from State University of New York in Albany is going to tell us about the elliptic periodic module and the 3D mirror symmetry. So please take it away. Yeah, thank you. First, I want to thank the organizers for inviting me to give this talk. Yeah, so this is some talk. It's a talk about my recent work with Christian Leonard and the guvans. So, yeah, here's the rough frame so I will talk about first mentioned some background about the equivalent elliptic homology and then I will say something about the elliptic homology equivalent elliptic homology of X of a variety and then I will talk about the construction of case theory periodic module. After that I will talk about the elliptic version, and then I will talk about the materialistic operators in the case and then the main result. So first, some background about elliptic homology. So the first part is but I mean there are many motivations many reasons of considering elliptic equivalent elliptic homology the first one comes from for me actually. The first one comes from the correspondences between three different objects. So the three big circles. Okay, the first one is about our matrices. So basically they are talking about solutions of classical Young-Baxter equations. So there are three types of solutions. For example, the other one, trigonometric, and the last one are called elliptic functions. So there are solutions of Young-Baxter equations and they can be used to construct different types of quantum algebras. The first type is called Youngian. The second one is called quantized universal European algebra. The last one is called content elliptic algebra. So basically there are algebras defined by using the generating relations using our matrices. That's my understanding of this. And the second category of objects consists of contains the one dimensional commutative formal groups. There are three types. They come from I mean the ones that come from outbreak groups. There are three types. One is the additive formal group. Second one is the multiplicity formal group. And the last one is collection or the elliptic formal groups. So that's the second collection of objects. And the last one is the generalized module series having some classes. So there are three types. The first one is the equivalent commutative. The second one is the equivalent k-theory. And the last one will be the equivalent elliptic commutative. And all the three collections, they correspond to each other. So for instance, equivalent commutative, they give you the additive formal groups. And they give the rational armature which gives the Youngian. Okay, for k-theory, you have the formal group will be the multiplicative formal groups. And then they will give you the universal UMMP algebra, the quantized version. And then also this quantum elliptic algebra, they correspond to the elliptic formal groups. And they are supposed to correspond to equivalent elliptic homology. Okay, so that's the relation between the three categories or three collection of objects. And that's the one of the motivations of considering this equivalent elliptic homology. So this is a theory. So the axioms are given by Gimburg, Kaplenov, and Vaselrod. They give some list of axioms, and that's in 1996, I think that's an archive paper never published. And the first construction was given by Gronowski. Basically, the two work appear in the same time almost in the middle of 90s. And later on, Ruri and many others have studied such theory, Ruri give a general construction of equivalent elliptic homology, and using this derived algebraic junction. So, and there's a lot of more people involved, so I couldn't give the complete list. Okay. So that's the first reason of considering this equivalent elliptic homology. So the second part comes from this so-called 3D mirror symmetry. So that's some theory from physics, theoretic physics, and the mathematical statements is made more concrete or precise and rigorous by recent work of many people. So there's a lot of logic, Akonkov, Romani, Smirnov, Vachenko, and so on, and there are many more others, mostly from Akonkov school. So the statement is, so it's more like correspondence, conjunctural correspondence between different objects. So here, X is a symplectic variety, symplectic resolution, and then it said there's a mirror of this variety, we call it X shriek, that becomes a standard notation. And then there's some correspondence between the two sides. The first one is that, so both of them will have torus action, so you have a torus acting on X, you have another torus acting on X shriek. And so then they satisfy this property, that is, so if you look at this diagram, so you have considered X cross X shriek, and now if you consider W from one of the t-fix points of X in X and W shriek, a t-fix point, a t-shriek fix point, then one can consider like this embedding, and also the other embedding, then what the 3D mirror symmetry statement says is the following. So there's some line bundle over this, so this equivalent elliptical model G of X cross X shriek, you can think of this as a variety. Okay, so over this variety, you have a line bundle. Then you can consider some section, they exist on section M, so that if you pull it back, you get a section over this variety, equivalent elliptical model G of X. You can also pull back to here, to the X shriek side, you also get a rational section. And then the statement says that, first of all, the t-fix points of the two sides should be bijective to each other. So it will map W to top shriek, that's how you identify the bijection between the t-fix points. After doing that, then you can look at the pullback of the regression sections. And then they will give you the so-called elliptic stable envelope defined by Aghanagic and Okonkov. And lastly is this identity between stable envelope, you can restrict to a t-fix point V. And for the other side, you can look at stable envelope for X shriek at V shriek, and then you can restrict to W shriek. Now notice that then you have this identity between the two sides, okay. But this identity is an identity up to some normalization. So in other words, you have to normalize the stable envelope by some factors, okay. So this three gives the 3D mirror symmetry statement of Okonkov and Aghanagic. So of course one can notice that this W and this W shriek, V shriek, they are switched, okay. That's one of the properties. And also some comments about this 3D mirror symmetry statement. So it's conjectured that this X and X shriek correspond to the so-called Higgs branch and the Coulomb branch, okay. There are two concepts from physics and I believe that Higgs branch is already constructed and is relatively easy to understand in math. It's some kind of hypothetical question, I think. Sorry, I'm not familiar with that. And the other one, Coulomb branch is constructed recently by this, by three mathematicians, Riveman, Fingerberg, and the last one is Nakajima. So one yard of space. So that's just some recent work. So there are a lot of things to be studied in this area. And the other thing is, the other remark is that this 3D mirror symmetry is also related to this symplectic duality, okay. That's also some mathematical statements concerning this category O and this cultural duality. Also, I didn't mention that the stable envelope. So we're going to define it later, but for now you can think of it as some rational section over this variety, okay. And it's indexed by the fixed points. So give you any fixed point, you will have a stable, a rational section that's for the stable envelope. That's the elliptic version. There's a similar version for case theory and the chronology that's well known. Okay. So that's the second motivation that I think one should consider you can run elliptic analogy. So, before I continue with any questions. Okay. Now the third motivation that one wants to consider elliptic homology equivalent elliptic homology comes from this study of elliptic genus. This is some work done by Boris off the global and later on it was used in this super calculus by the money at Weber. So basically, one wants to consider elliptic classes for a singular variety and then it turns out that you have to consider pairs instead of just one thing singular variety. So you have to consider pairs with a real divisor. So, what is off the global, they constructed this elliptic classes for the pairs, as well as this status. So this pair is a KLT pair KLT links for power model log terminal pair. Okay. Then after you if the pair satisfy this KLT condition then you can define this elliptic classes using you can use resolutions and they prove that this definition of these classes does not depend on the choice of this resolution. So if you want to study this construction for super variety, then there's a problem because this super variety together with boundary is not KLT so you cannot just apply this Boris off the global construction. Okay. And then it was realized by the money at Weber that instead of considering the boundary of the super variety. You can choose it or shifted it by the line bundle determined by this character lender. Okay. And as long as this lender is regular. This pair will be a KLT pair, which means this Boris off the global construction can be applied. Okay, so that's why in this case you can define these classes. Of course, in this case, then you have an actual parameter coming up that is this lender. Okay, so this lender in this case is called this dynamical parameter. Actually, some people I mean or cook off and some people also call it Kayla parameter. Okay, so that's the reason why the dynamical parameter comes up. Okay, so then the elliptic case, people can quite elliptic homology with the elliptic heck algebra or elliptic the materialistic operator with dynamical parameters. Okay. And the definition of this, of course, is resolutions and the canonical resolution is this for the semester resolution that exists for any shoeboard writers. So that's how this is defined. And because for the semester resolution is constructed recursively. So then this, you know, operator, the materialistic operators are defined. Okay, so this elliptic version of the materialistic operators are defined. And because of this body softly go goes work, such the classes defined in this way does not depend on the choice of the resolution. So automatically, it will tell you that is the operator satisfy the bridge relation. Okay, and of course there's one more relation that is the, what if you take the square. So if you take the offer the square is going to be equal to one. So it behaves like a while group. Okay, any questions. So, let's continue. So that's the background about this three reasons that I think people should consider equivalent elliptic homology. So, for us, we will not use the construction here is that we use the logic modules. But before that, I should say something a little bit about equivalent elliptic homology. So, for that one, once you start with the point and that's the easiest case. So if you consider equivalent homology of a point, we know this is equal to the symmetric algebra of the group of chapters. And you can think of elements here as functions polynomial functions over this T's lowest star tensor C. Okay. So similarly, if you consider the case theory, it will be just the symmetric at the group ring. And again, you can consider that as functions over these colors. So here, of course, he lowest size, just free of being group. So this gives you a product of C star. So that's why if you take the spectrum, you will get a fine space. And if you take spectrum of the case theory, you will get the torus. Okay, so that's why if you consider the elliptic version, you will be looking at functions over. And there's a typo, as you put it here is an elliptic is the elliptic curve that you fix at the beginning. Okay. So, and then, if you take the spectrum, you're going to get T low star tensor E. Okay, this is the variety that we call it a. So it has morphic to E to the m is the length of the torus. So actually, I put this way, but in the remaining part, I will also always consider this spectrum. This a, as equivalent commodity of a point. So yeah, what's from now on, if I say equivalent commodity of a point or equivalent commodity of a variety. I'm talking about some IBM writing. So in the point case is just this IBM writing for general X, it will be a variety over this EM. Okay, so that's why we define this a to be this T low star tensor E, and then the dual of this ability is T up a star the group of chapters tensor with E. So the tensor is over C, okay, over the ring of integers. And that's also isomorphic to the degree zero pick up group of a. Okay. So that's why that's why it's called the dual ability. So I made another mistake. So I will just think of elliptic homology of a point as a itself. Okay. And so when we talk about elliptic classes, we are talking about some rational sections of certain line bundles over this variety and now if you consider the T fixed points, you can embed it into here and then you have pullback of elliptic classes, you can restrict to the T fixed points V. Okay, then in this case, this becomes a product of elliptic functions over the over a. So this becomes functions over this a this ability right. Yeah, also I should say that these elliptic classes of the money waiver, they also corresponds to the stable envelope of agonistic. Okay, this is stated in the money and waivers original work and I think for some cases, this identification is not written down yet. Okay. Okay. So that's the setup of this equivalent elliptic homology of varieties. So there are varieties. And so to continue, I would like to first review some part from case theory that's a classical story about case theory of Cotanium Mando. So, we know that this alpha and hack algebra. This is as a morphic to this case theory equivalent case theory of the fiber this standard variety. So this is already noted by the standard variety. And this work I should refer to rustic. Some classical work of the tool. So basically, one can identify this hack after hack algebra with this case theory of alpha of the standard variety which is a singular variety, and then it acts on case area of Cotanium Mando by convolution. Okay. And of course, you can look at the T fixed points of this Cotanium Mando, which will be projected to the wild group. So then you can go back to T fixed points case area of T fixed points. So this is called the restriction. So then inside this alpha hack algebra, that's one special element that's called the materialistic operator for case theory, usually people denote it by T alpha, alpha is a simple root. So this, the presentation of this operator can be written as this fraction plus this one plus S alpha, S alpha is the wild group action. Okay. And then you can let this, this is an element. This is a class or class in this case theory. So it will act on the case of case theory of the Cotanium Mando. And then, for instance, you can take a special element, the class corresponding to the identity points. Okay. So, then this T alpha by definition is, it belongs to this key product. Okay, that's the group ring of wild group. And this is the field of fractions of the case area of a point of course we know that this is basically this group ring. And they add this actual parameter, because of this C star action. Okay. So this work actually refer to custom kuma that's not classical work. Of course also realistic. Sorry. So, T alpha you can think of it as an element in this product of this field with this group ring, and they set by this quadratic relation T alpha square is equal to q minus one T alpha plus q. So now if you, they set vibrator region so we can define T w. Okay, after defining T w, then you can let the T w, which comes from the affine heck algebra, you can let them act on this fixed point. Sorry, this, this class that you fixed at the beginning. And then you will get some classes indexed by the by the world group. So this is the case theory stable basis for w. Okay. So case here stable basis was constructed by Molyk and our concoff and of course this case theory stable basis depends on many several parameters depends on a chamber polarization and slope. So this identity is just for one of them you have to fix some special chamber polarization slope. For example, this identity was proved by my work with Sun Jian Su and Goofang Zhao. And also, there's another story related to this that is, it's also equal to this motivation class of super cells. And construction coming from electric geometry. So that's some work of a Luffy mihasher Schumer and Sue, and also for type A, type A flag right is, that's also studied by Lemanian wiper. Sorry, Lemanian vachenko. Sorry. And I think I should also put the taros off. These three are for type A and then Luffy mihasher Schumer and Sue, they work for general Schumer right, general jima b, not just for type A. So that's the story for case theory. Okay, any questions. Okay, so as I said that's the case theory case and so basically this is called the periodic module. Okay. And for elliptic case we can start to do elliptic case and what we want to do is we want to mimic this action. And also this module and then this operator. Okay, so, so far everything I mentioned are not done by us. I mean, some of their classical and some of their recent. So now for the elliptic version, what do we do is the following. This is the concrete line bundle over this A cross a dual. So basically, this concrete line bundle will classify all the degree zero line bundles over a. Okay. So, and we look at some shift of P. This L is defined to be P tensor with all of H row. Sorry to H row tensor with all of negative two H row check. So here, H, it's an element in E that you fix at the beginning. This corresponds to the C star action so we have fixed an edge first. And this row, all of two H row. So, H row, row is an element, low is the sum of the positive rules and then divided by two. So to H row is a special element in a check. And then this all of two H row will give you a degree zero line bundle over a. And similarly this one will give you degree zero line bundle over this a check. So take the tensor and then tensor with P. That's the shift of this L. Okay. And then there are two, the well groups acts on a, because a is the T low star tensor E so well group acts on the group of collectors. So you have a well group action here which can define a well group action on a. And similarly, you have a well group action on a check. Okay, for the second one we call it w d is the initial for dynamical. We have two well group actions on a cross a check. And then we can define this as to be this w up star. V D star so D means dynamical so V D star really acts on a check w acts on a. So with these two actions you can pull back this L inverse and then you can tensor with L. This defines you a line bundle and then you can take the direct sum over all the W V in capital W. Okay, so of course, in case, in case if you repeat this construction, this bundle will be a some of it. So, because over C star in the case here case, you will be talking about over this torus and over this torus. You, this is our fine so you don't need to really worry about line bundles, but over a or over e elliptic curve that's projective variety so you cannot just. It's not our fine so you have to consider line bundles. So that's why we have this construction. So this is what we call the twisted group extra. The elliptic version of the one with dynamical parameters. Okay, so this is a line is a vector bundle over in this choreography. Shift of category of coherence shifts over a cross a check. That's a type of a cross a check. Okay, and it's also. So because of this piece, we can think of this back bundle as a algebra object in this by graded coherence shifts over across a check. So we can define a tensor product structure in this category and then this as becomes an algebra object. Okay. So this is the definition of this twisted group extra. And of course we can consider the quotient of a cross a check into the file into the wire group action. And this will give us a print an action of s on this L more precisely you have to push forward to this variety. So as to get this action. Okay, one other way to do that is use the tensor tensor structure over here. So that's what we call the, so this L is called polynomial representation. It corresponds to the, if you recall before, it corresponds to the action of this after I had captured on a T cross C star of a point. Okay, which is, which is the group ring. Sorry, it's already here. Just this one. Okay, that's called a polynomial representation. And then in the elliptic case, the polynomial representation is really the action on this line bundle L. Okay. So that's the definition of this polynomial representation and then we can talk about the periodic module. That is this one. Okay, this is to mimic the idea that for potential bundle. So what we can look at is T fixed points and that's just w. So that's why if you consider elliptic homology of these fixed points. You will be looking at elliptic homology of w which is basically direct sum of a lot of copies of a structure shift of a, but if you replace the structure shift by the line bundles. It will be this one. Okay. So the W is really to indicate the degree. So this becomes. So both of them. So this becomes a object in W graded coherence shift in a cross a check. Now for the dynamic version, you can do similar things. You can also apply the dynamic of our group action, which acts on the second component. So then this becomes an object in the coherence shift, the W graded, more precisely WD graded coherence shifts of O A cross A check. Okay. So that's the definition of this periodic module and we have an action of this S on L as I mentioned L and also we have action of S on M and action of S on M D. So the D will serve as the equivalent elliptic homology of T star G over B, where you have to replace G and B by the London's dual. Okay. Because the roles of the torus and the dual torus and the torus and the London's dual torus, they are switched. So that's the definition of this M D, the periodic module for the London's dual, and that's the periodic module for the loose system. And then with that we can start to define this, the materialistic operator in elliptic case. So for that, I'm sorry to interrupt so we usually take a few minutes break in the middle of the seminar I don't know if this is a good time to have a little break. Actually it is. Yeah, thank you for reminding me. Okay.


All right, wonderful. Please note everyone that we are recording the session and we're also live streaming. So say hello to the live stream as we go there and Igor will put that onto the chat and feel free to share it on social if you want others to join us today as well. So welcome everyone. Good morning, good afternoon and good evening depending on where you are zooming in from today for our final 2021 Hyperledger in-depth hour with members webinar. And today I am happy to have Chris Cordy who is a software engineer at Splunk join us. Splunk is a monitoring and analyzing machine-generated data company and Chris will provide you an overview of Splunk as well as his role there and then go into the discussion for today. So before we get started a couple of things, housekeeping that I'd like to do first any of you who have not been to any of our Hyperledger community webinars or meetings all are welcome in our community and we are committed to creating a safe and welcoming community for all. So please adhere to the standards of the Hyperledger Code of Conduct which is on our website. And if you have any questions, please let me know ultimately be good to one another and let's be productive and constructive with one another. A couple of other housekeeping rules just like any other Hyperledger community meeting all our meetings are under our anti-trust policy and that means that participation by industry competitors, we wanna make sure that all activities are conducted under that policy. Please review the policy if you have any questions on our website. And during this webinar, if you have any questions please direct message me and I'll be happy to assist you. As a reminder, once again, the webinar is being recorded and they'll be available after the fact and you can watch any of our webinars in our Hyperledger webinar library as well as on the YouTube channel where we have hundreds, sometimes it seems a week, presentations from our special interest groups, our working groups and our meetup community which continues to grow. The slides will be available for download after the presentation you'll get an email from Zoom directly with some links to that as well. So our goal is to have these as interactive as possible. So I'd like to take you through three ways that you can communicate with us during the session. Number one is if you're familiar with the raise hand feature in Zoom, you can go ahead and raise your hand when we open up for questions and answers and we will go ahead and unmute you and you can ask your question via voice. You can also use the ask questions feature in webinar in the Zoom webinar. So click on the Q and A and ask your question there and Chris and I will get to those when we open up for the Q and A as appropriate. And last but not least, feel free to talk and comment during the session in the chat. Once again, please be respectful of others and we would be happy to address any of those and if you wanna voice chat, we can as well. So once again, this webinar is for you. We wanna make sure that you get the best out of it. So without any further ado, I'd like to pass this over to Chris Cordy who's, as I said before, a software engineer at Splunk and one of our Hyperledger fabric experts in the field. So Chris, over to you. I'll go ahead and stop sharing and you can share your slides please. Wonderful. Yep, we could see them. Awesome. So thank you for the introduction. I'm Chris Cordy and I'm gonna talk about how you can secure your Hyperledger fabric deployments using Splunk app for fabric which helps you monitor all the security and infrastructure events happening on your Hyperledger network. Okay, so this is me. I look a little bit different right now, I guess. So I'm a software engineer on Splunk's blockchain team and there I work on a few of our integrations that enable you to pull data from different blockchains like Ethereum or Hyperledger fabric. So in particular work on Splunk Connect for Ethereum and Splunk Connect for fabric and I also am very involved in adding the features for detecting different security events happening on those networks. Prior to working at Splunk, I worked at Sandia National Labs where I was a cybersecurity researcher. So I've been interested in cybersecurity research and blockchains for a long time. So why Splunk blockchain? For those who aren't familiar, Splunk is a tool that allows you to turn data into doing. There's tons of machine-generated data created by organizations, all different endpoints, network devices and it's hard to make sense of all this data. So Splunk allows you to take all that data and correlate based on time between all these different sources to be able to make intelligent decisions for your business. So in particular for blockchain, blockchains generate tons of data. Blockchains are also often complex and organizations that are using blockchains often have a lot of other, a lot of other infrastructure that they wanna monitor as well. And they're really interested in monitoring the interactions between their traditional enterprise infrastructure and the blockchain infrastructure. So Splunk can help you get visibility between all the different components in your blockchain deployments. We support many different blockchain technologies and so you can take any sort of data source and throw it into Splunk and be able to make intelligent decisions. Cool, so just as an overview of what we'll be talking about today, hyperledger fabric, I'm sure everyone here is somewhat familiar with it, it's designed to enable secure collaboration between multiple organizations with limited trust between them. So notably hyperledger fabric has a slightly different security model than public blockchains, like public permissionless blockchains like Bitcoin or other cryptocurrency, hyperledger fabric, it's permissioned. So all the parties should be known and they can be accessed and built. So these security improvements can make it, in some ways make it easier to make secure deployments and to trust that your network will be operating correctly and reducing your risk of attack. But you still need to make sure you're carefully configuring a network and monitoring it to make sure that no attacks are happening. So we're gonna review some different types of threats and then some different types of threats than hyperledger fabric networks face and discuss how to mitigate them. Okay, so first it's always good to think about what assets you're trying to protect. Obviously data would be very important to protect like the intellectual property or other sensitive data, hardware and software or applications, which is very similar to data. And make sure that your software is running correctly and isn't being manipulated. As mentioned earlier, hyperledger fabric is a permissioned blockchain. So its threats can differ from popular permissionless chains. Still some attacks are common to all distributed systems like Nile Service or consensus manipulation. Other attacks target specific components in a hyperledger fabric network, such as a membership service provider. So for the first threat, we'll look at denial of service. Nile service attacks disrupt the network's availability and any distributed system is vulnerable to some extent to these. Many different attacks can also cause denial of service and it could be difficult to proactively prevent. For mitigation, it's good to be collecting performance metrics, such as transaction throughput and latency to help detect if an attack is happening early on. Consensus manipulation is another risk on a hyperledger fabric network. So hyperledger fabric doesn't quite have the risk of 51% of attacks in the same way that Bitcoin might because it's permissionless. Still there are attacks on network consensus that you can do including denial of service and transaction reordering attacks. So we wanna make sure that the consensus component seems to be acting correctly in our hyperledger fabric deployment and a way that we can try to make sure that it's happening is we can log some threat indicators like leadership elections and transaction lances to speed up detection of any malicious behavior. Basically, we wanna make sure that the consensus elections and decisions aren't being hampered in some way by one of the parties. Another threat is MSP compromised. So in hyperledger fabric there's a membership service provider for the MSP and the MSP is able to modify access control to the network. And if it's malicious, it can deny service to parties and perform civil attacks, which is not good. So the MSP can be compromised by Rogan Cider or through PradaKeitha, which are generally gonna be pretty difficult to detect until after exploitation happens. So to mitigate this threat, you're gonna wanna follow key management access control best practices. Don't share keys, make sure all accesses are logged and then also you're gonna wanna log an alert on your MSP actions, such as the creation and revocation. And then another threat is smart contract exploitation or chain code exploitation. So the risk in hyperledger fabric for smart contract exploits is that business logic can be compromised and so can network performance. Again, we're not worried necessarily about lots of money or it's not gonna be very obvious that lots of money was stolen, like it might be encrypted currencies, but we still wanna make sure our business logic is running correctly and that our services aren't gonna be down. So in addition to just smart contracts are often written by people and people like to make mistakes when they program, including me. So in addition to some of the ordinary logic bugs you might have, you can also have errors resulting from trying to handle concurrency or a nondeterminism, which can be difficult. So mitigations for this include like all other programs, smart contracts should be designed with security in mind and at the onset. Smart contract analysis tools like the hyperledger lab chain code analyzer can help scan for vulnerabilities before you deploy your smart contract. So you can proactively know that you're not putting out a vulnerable contract. It's also recommended to request an external security audit. And then finally, like all the other threats monitoring is key here. You should monitor performance and usage of your smart contract and detect any anomalous behavior. So to distill this a little bit, here are some of the key data sources for all the threats we just talked about. So for denial of service, we have transaction throughput latency, block latency, and the number of senders of connections. I'm not gonna read this whole table, but take a moment to look at it. Notably, we see that there are different data sources that we need to grab and be able to correlate between. So we have block headers, blocks, node metrics and logs and any results from a vulnerability scanner. Additionally, there are other threats that I didn't talk about that we potentially wanna be monitoring for. On the last, we see a list of even more threats and we see all the different data sources that we might wanna collect from. New from the categories before, we see we're gonna wanna bring in some threat intelligence information, peer-to-peer and network information. Maybe we wanna call some APIs on the node and collect some client or front-end information. So there's lots of data coming from off-chain and on-chain and from lots of different places. And this data can, these are many different types of data. They look different, so it can be difficult to try to make a correlation, especially if you don't know what the data would look like ahead of time. So that's why we have this data to everything platform where you can take all of your logs, metrics, traces and ledger data and throw it into Splunk and be able to make informed decisions for your IT, security and observability of your networks. So how do we do this? So in particular for Hyperledger Fabric, we have the Splunk app for Hyperledger Fabric. It lets you get visibility into what's happening on your network, so you can monitor, troubleshoot, investigate and take action on your Hyperledger Fabric components across organizations in different cloud environments. And this crucially allows you to reduce your main sign of recovery because now you have all this data in one place. And then now if you're trying to get the production faster, it's a lot easier to see what's going on, understand what's happening with your development changes and then monitor whenever you make changes what the effects are. So this app can be found on Splunkface and the app is also on GitHub and you can look at it. The link is accessible through the Splunkface page. Cool. So now how do we get started with the Splunk app for Fabric? We can easily ingest all these different data types by using the following tools. So we have the Splunk Connect for Hyperledger Fabric to grab ledger and metric data from the deployment. As an example, we can use a Splunk Docker login driver or Splunk Connect for Kubernetes to send container logs to Splunk. And then finally the Splunk app for Hyperledger Fabric is what allows you to visualize this data in Splunk. And it has example dashboards for infrastructure transaction analysis and security. So if you go to this GitHub page, then you can see some example networks that you can run in Docker Compose to get started. Cool. So we would have a very simple bare bones network. We might have a somewhat similar configuration to this. We have an organization that has two tiers in order. And then we have a collector here that grabs metrics from Fabric and the containers. We can use Splunk Connect for Kubernetes to grab container logs. And we can use Fabric Logger to Splunk Connector to grab Fabric events and block data. And we can throw it out on Splunk. So if we were to do that and then take a look at what the security monitoring dashboard looks like, we see the following metrics. We see transaction latency, throughput, number of unique senders, and then a few graphs of transaction count, number of GRXPC connections, and number of TLS connections with orders. We can also see some config updates, consensus leader changes, and whether any blocks have been orphaned, which meaning here, is there any block number that was, is there any block that had a different hash for the same number on the same channel, which would be very bad. So we can see that we have denial service indicators and our consensus manipulation indicators here. So let's see an example of what this data would look like if the denial service attack were to happen. So say we had a scenario where an authorized user has their keys compromised, the user begins spamming the network with transactions, what would we expect to see? So we should probably pay attention to the transaction latency, throughput, and number of open connections. So in order to get a baseline, let's look at a normal case where a single client is sending 10 transactions per second. So this is our baseline measurement. And in the normal case, single client sending 10 transactions per second, we see the following graphs. You see transaction latency is fairly small under 200 milliseconds. We have the throughput we were hoping for, 10 transactions per second. We see a nice constant slope here and for transaction count over time. And we see that net gRPC connections open by node is staying fairly small with no gRPC connections exceeding eight. So now let's look at an adversary scenario. If we have another client who tries to open up a thousand connections at once and it's performing one query per minute, and then we would expect to see a transaction latency starts to increase, transactions for second decrease, and the number of open connections increases. Basically, we have a client that is trying to stuff as many connections as possible and not closing them, which is gonna be exhausting the number of open connections available as well as exhausting CPU cycles on whichever period is connecting to. So we see this is what some adversary, this is what the results of that would look like. We see in transaction latency that the latency has started to increase from around 180 milliseconds earlier. You see transactions per second starts to decline. You see a bend in the transaction count over time graph. And you see that the number of open connections starts to balloon. So at this point it's difficult to determine do people really like to use our service? Do we just misconfigure something or is someone actively trying to attack our network? So we can drill down on the errors to try to figure out to get a better idea of what's going on. And if we do that, we can see that these error messages are caused by TLS handshakes and IO timeouts. And because we saw a large number of open connections, we can ask Splunk to tell us what does the distribution of these GRPC messages, message subjects, what does that look like? And in this very simple case, we can search all the GRPC messages, peer subjects, and group them by subject and count them. And when we do this, we see that one subject is responsible for the vast majority of these counts. So because of that, we might be inclined to think that this certificate is compromised or that something is misconfigured and should be investigated further. So now let me see if I can show what this looks like on a dashboard. Cool, so now I wanna show this on an actual dashboard. So this is what it looks like when you first start the app. You have all these different dashboards to choose from. And as a warning, this is a Splunk and Sins where the denial of service attack is currently happening. So we might see some weird results here. So if you click on the network architecture and channels tab, yeah, okay. So it's gonna love it slower than it would otherwise. I don't know if that's, let me close the keys. Okay, the demo guides always get us. Yeah, I know. All right, so that's fine for now. There are other screenshots that show this, but we can see the number of hosts, containers, peers on a network. This gets a very holistic view of what the network looks like. Okay, so actually this is that dashboard right now. Sorry about that. So it's a number of power hosts, Docker containers, which has a peers, catch UV instances running. She's a very holistic idea of what this network looks like. And then we can go to the infrastructure, health and monitoring tab. Here we can get some system metrics and some fabric metrics. So if we see these errors, we can drill down on them and so I was showing earlier and we can see what some of these error messages look like. And we see lots of IO timeouts and connections reset by peer. And we see transactions per second is not close to 10. And transaction latency is also significantly above 200 milliseconds. Okay, and then if you're trying to drill down a little bit more, if this were a security issue, what do some of these security threat indicators look like? You can go to the analysis service indicators and we see that the situation is just getting worse. Transaction latency is increasing even more. Transactions per second is now under one. And we're seeing a significant bend in the slope of these transactions count over time. And that your perceived connections is in the thousands. But we don't see any consensus manipulation indicators firing right now, just the analysis service ones. Okay, so finally, if we wanted to see what are the sources of all these transactions, we have the sources here and we can see that this user is responsible for most of these transactions and I'm sure if I drill down a little bit more recently, we would see that this is actually more than 90% of the transactions. So we would probably wanna look into this certificate, this user and see if that has been compromised or if this is expected behavior from here. Okay, so I think that is all I wanted to show you these dashboards right now, but people can feel free to ask further questions. And then for the last couple of slides here. So yeah, we showed how you can drill down on some of these errors, how you can get a holistic view of the infrastructure and then also the security dashboards to see these particular indicators, which ones are firing, but then what can you do from there further? So once you identify, should you do a little bit of triage to identify a little bit more narrowly where the issue might be, you can integrate this information with other tools like Splunk's APM or on-call to get your real-time observability metrics and then quickly dispatch alerts to staff whenever there is a service outage that they need to look at. Splunk Enterprise Security allows you to enrich and prioritize the different notables or security events that we're seeing based on risk. So those IO timeouts that we saw can be given away and whenever those happen or if some threshold of them happen that can be seen as more risky and we can act on that. And then finally, Splunk SOAR lets you automate parts of the incident response process. If you notice some certificate or some users seems to be compromised, then you can start taking automated actions to remediate that, such as changing firewall rules to prevent access. And for an example of who is using Splunk app for Hyperledger Fabric, we have this S&P as the case study with us and it's published on the Hyperledger website. And they're using that to make sure that their data is not, they want to use Hyperledger Fabric to make sure that their data is not being tampered with and then Splunk helps them get visibility as we're trying to build on top of that. And to have the confidence that's working correctly. Okay. And that's all I had for slides. You can go to splunkdlt.com if you want to learn more about all the different Splunk apps we have and integrations we have. And at this point, anyone has any questions? Please feel free to ask. Okay, everyone. And just as a reminder and I just put it into the chat as well, there's three different ways that you can use Splunk. There's three different ways that you can answer, ask your questions of Chris. You can raise your hand if you want to do a voice call. We'd love to hear from you and it's always great to, or even make a comment if you just have a comment or you're working on a project that you want to share some information with that you think is relevant to today's discussion, please go ahead and raise your hand and we'll unmute you. You can also ask any questions that you might have via the Q&A. So just click on the Q&A in the toolbar and go ahead and ask your question. And last but not least, feel free to use the chat as well if you want to make comments or ask any questions as well. So opening it up for any questions or comments that the audience might have today. Thank you, everyone, for sharing with my demo also. No, no, it was great. It was great. Chris, I have a question for you, specifically about the use cases, the use case that you mentioned, the case study that you mentioned, and maybe I don't know, Melanie, you're on the line as well and maybe you can address this. To talk a little bit about where S&P Global as their network, some of the benefits that they've seen in using Splunk. Sure, yeah. So yeah, potentially Melanie can answer this, we expand on this a little bit more, but essentially, data tampering is a very large threat that organizations face. And so that's a motivation for lots of organizations to want to use blockchains to help secure their data, especially when they're working with other organizations that they might not trust too much. So S&P, like other organizations, is interested in using blockchain for this data integrity problem. And essentially, it can be difficult because these are newer technologies to really understand what's going on. The tools aren't quite as mature as they are for regular software development stacks. And so it's very helpful for them to be able to easily have visibility into what's going on with their data to be able to see the logs and metrics for both the fabric network and the rest of their network and correlate between them. And then also to actually see the chain code events happening was also helpful. So basically, visibility and being able to understand what's actually going on with their network. But yeah, Melanie, from now, feel free to expand. Tristan did an amazing job. I think the only thing that I would add is probably the nature of the use case with S&P, which was multi-cloud and Splunk just being a partner of S&P for many decades now. And bigger than this particular use case, most of the infrastructure is automated with Splunk at S&P. The Arpillager use case that is being explored alongside with Splunk and S&P is interesting because of the complexity of the infrastructure and how Splunk easily provides a robust solution for everything monitoring and observability in that complex stack. Okay, great. And I posted the case study as well in the chat if anybody wants to go grab that during the session today. Excellent. I see a question, Chris, on the Q&A from Sinez around did you make any changes to the hyperledger fabric infrastructure or did you design the dashboards on the data? So this is pretty similar to the test network example in the hyperledger fabric docs, slightly modified. So for the chain code I'm running, there's an event that puts a message out or added X to this account. So that in the dashboard, we can see in the dashboard we can see those chain code event messages. So that's one change and not really too much more. A lot of this is just using or being able to grab the logs. So either through Splunk Kubernetes or some other connector and then hitting one of the peers endpoint, basically hitting the API on one of the peers and then fabric logger can grab chain code blocks, headers and events from there, but not too much. So the dashboards were mostly designed on the data generated from the example test network. And then in the GitHub page, you can see in the example, if you run that data being generated and put into the dashboards. So the answer is yes to both, but the dashboards are pretty accessible for if you end up changing your network further. Okay, great, thank you. So now as if you have any of the questions you can just add the additional comments onto the chat as well. Chris, I do have a question specifically, like as you think about, you know, critical KPIs that people are looking for and they should be monitoring, like what are the top things that you're seeing, your customers and the consortiums that they're putting together, wanting to monitor specifically? So, transactions for a second is probably always going to be the key one. It's very much, it gives you a good idea that something might be wrong, but obviously it doesn't quite tell you much about what might be wrong. So it's still good to know. Any hardware measurements, so like RAM or CPU utilization are also easy to collect. It can be very informative if nodes are starting to have trouble or going down.  There's no segmented parts of your network that would make it perform suboptimally. Those are the big ones. And then also, you certainly always wanna know if any of these services are spitting out errors. And those should probably propagate to errors.  So being able to grab errors out of logs is also very important. Okay. And I do have another question around, obviously all these networks are consortiums, multiple companies. It seems like in order for it to get full support of the network that every participant would need to be on the app together or is that not the case? So, you get a lot more benefit if that is the case. You do get more visibility. But even without that, you have a lot of visibility into all the present network that you're able to see as a single participant. And then also again, yeah, with correlating between all of your organizations. Existing infrastructure, but yeah, certainly the benefit can be greatly increased if you can combine information from the different organizations. And have you seen that in production, sort of different companies working together, you know, basically sharing the analytics on the network? So I've seen companies working on that, yeah. Okay, great. Any other questions? I do have one additional question, but I just wanna, before I ask that one, if anybody has any questions, once again, just put into the chat or raise your hand and just make sure nobody has their hand raised to ask questions. So I will go ahead and ask mine. So obviously today's presentation was focused on Hyperledger Fabric as one of the supported DLT platforms. Can you talk us a little bit about what other Splunk support of other blockchains, either within the Hyperledger Foundation or outside of the Hyperledger Foundation as well? Sure, so within, so we have support for Bezu as well. So yeah, Hyperledger Fabric and Bezu support for Ethereum. So if you have any Ethereum and Corda, and you can see those on the Splunk DLT page, you can look at all of our existing integrations. But yeah, definitely those are the big ones. So in the Hyperledger community, primarily Hyperledger Fabric and Hyperledger Bezu as well, for those of you who are interested in this, or Bezu as well. For those of you on the phone who aren't familiar with Hyperledger Bezu, it is an Ethereum client. It's been in the Hyperledger Foundation since 2019 and provides the ability, it's a patchy licensed Java-based Ethereum client, provides the opportunity for people to do both permissioned and public networks as well. So I encourage you to take a look at that. Any other questions, doesn't seem so. Chris, if you were doing a side-by-side with potentially other providers in the marketplace, what would you say are some of the top things that Splunk offers that maybe others in the market might not have? Yeah, so touched on a few of the reasons already. But a major one is plenty of organizations are already using Splunk for other parts of their infrastructure monitoring or for their security monitoring. So you can get a lot of added value if you're going to be using Hyperledger Fabric, or you're thinking about using Hyperledger Fabric, now that you can easily integrate that with your existing infrastructure and security monitoring tools. And then also the other integrations with on-call or SOAR that I mentioned earlier also. Great, thank you. I don't see any other questions. I noticed somebody put a link to Unblock Splunk DLT. Can you tell us a little bit about what happens when we go to that link? Sure. So that's a public dashboard that all of you can go to and which shows what the view looks like for some of our different apps and the different use cases you might use them for, others monitoring and observability, infrastructure security, and then ledger analytics. All right, and yeah, it's pretty cool. Hey, do you want to show us that since- Sure. Because if people are on the video and they don't see the link, they can't see it. That'd be great. So when you go to Unblock, that's on DLT.com, so you'll see. Shows the different use cases and shows what the view of a dashboard would look like grabbing data from. So in this example, yeah, we're grabbing data from different organizations or monitoring the health of a consortium. In this one, we're trying to, I'm not too familiar with this one, but we're trying to detect any fraud happening on the network here. And then you can drill down and do even more rich ledger analytics also. So for examples in Ethereum, Quota, Fabric, yeah. Great, okay. So Chris, I think since we don't have any more questions, I'll go ahead and wrap this up. If anybody has questions for you specifically, Chris, how do they go about getting in touch with you? Yeah, it's probably easiest to, again, touch me over LinkedIn. So people can find you on LinkedIn. And obviously if people have questions specific to the Splunk offerings, they can contact Splunk directly. Chris, I wanna thank you for today's session and for the demo. And once again, this session was recorded, so we will provide the presentation via our webinar library and everyone can download the deck as well. So we really thank you for your time. As Chris mentioned, we did recently publish a case study that Splunk was kind to work with us on with S&P Global. So highly recommend downloading that. And you can just go to hyperledger.org, learn case studies. So pull learn from the top navigation bar and then go to case studies and you can download that full case study that is available there. So once again, thank you to the Splunk team for working with the Hyperledger Foundation team and the S&P Global to get that story out. It's been great to see. So once again, I want to just let everybody know this is the last of this year's Hyperledger in-depth member webinars. But we are starting to schedule webinars for 2022 and unbelievably we're ready with almost there. And the first ones that we're gonna be doing are actually some project workshops. These are gonna be a four hour workshop series for Hyperledger Ares and Hyperledger Indy. So for those of you who are interested in learning more and getting hands on with both of those projects, Hyperledger Indy is our DLT framework that is focused on digital identity and self-sovereign identity and Hyperledger Ares is a library also focused on SSI and digital identity work. So please visit our wiki at the top of the wiki page. You can actually go and register for those events. Registration is filling up pretty quickly. There's limited seats. So if you're interested, please make sure to sign up now. So once again, we'll see everybody in 2022. Just as a reminder, we have some great content from our Global Forum this year and you can go ahead and go to our YouTube library and watch many great sessions that were conducted in June with our community. We are an open community as I mentioned. So please do get involved for those of you who are new to our community.
