Good morning everyone. I hope you are fine and you have a very nice Breakfast, so I think we can start yes first of all I also Thank my colleague Professor Padobani to ask me to come here. These are beautiful places in ICTP It is very prominent very famous, you know all over the world It is dream every scientist to be one times in ICTP Campus and you are here and they have many many many many activities not only medical physics Professor Padobani and his friend Bhattuchi they introduced medical physics. We are lucky enough that we have medical physics in ICTP I ask him maybe the capital of medical physics all over the world and you please Develop it thank Thank you very much. Yes The professor my colleagues and gunter introduced me. I am long time here like you From the developing country and I have a experience in Germany Little bit in Europe and of course in developing country in our society of medical physics in Germany We have a tax group. It's called medical physics in developing country. So we support not only in Bangladesh I was in Africa even in South America. So all over the world points anybody want to arrange that Something similar in your country then maybe in European level We can visit them on many many people. They want to do that. So we have a very short time I must also Maintain my time. So you have learnt many things in last three days I think you know from their propation also the medical physics medical physics is a new subject I think in the new subject not so new but in developing country new subject We are fighting against cancer, but at the same time we are fighting for our positions our salary So when everything we are fighting parallel So we are a very we should be a strong foot in the in the earth and try to find Not only in the hospital, but also in the government level. So you have a huge tax to do So your subject is not so easy, but it is challenging. I hope we are strong enough to do All the things parallel so that actually at the end there is a good help for the disease patient cancer patient. So here three dimensional conformal therapy. It is actually Important tools I know from many countries even in Germany most of the hospital they do the conformal conformal radiotherapy and in some places Also I am RT in German even They do not like to introduce I am RT because is a many problems there even the Insurance do not pay for that did not pay for the I am RT, but now they pay also for I am RT So I am RT is actually increasing every day today So Yeah, I think you have seen this from IA everybody. I do not actually explain the tax of medical physics Medical physicist you know more or less everybody it started from the construction of the bunker up to the up to the Treatment of the patient. Yes, this is all the tax for you. What I want to mention here actually Here you see the these are the partners in the hospital. Actually you have radiation oncologist and technicians some countries like America. They are telling radiation therapies They are technician so the three person in a group and team and it is your duty to work together Only when you work together, then you have a good quality assurance Yeah They feel sees the work when alone they have some quality control, but not the quality assurance Yeah, not the outcome of the passion. So please do a very close contact with them Yes, not only sitting your dark room with some Computer treatment planning, but you always go to the positioning and other cases where you have a close contact the Hospital authority especially the medical doctor knows every day passion passion Added in the meeting not somewhere in dosimetry summer treatment plan Nobody knows what you're doing and you are afraid because nobody knows or nobody respect you But they do not actually know what you are doing. That's why the patient passion Close is very important for you. Yes so this is a teamwork and Teamwork is very important. I'm telling the full quality assurance. This is all to the chain, you know From the professor Hartman what I want to say here actually the 3d amazing here started Everything there you have many many modalities. So we can actually Find the tumor very well. Yes, so we can also Contour is very well So you can escalate it that can you can clue you can actually Hire the dose. Yes in earlier time the dose is limited by the tolerance of the Organic reeks, but when you have a very good contour and you define the PTV very well then you can Increase the doses so the outcome is very nice. So this is actually not only the treatment planning But 3d amazing is a actually very important and and here is at the education of medical doctors is very necessary Because most of the medical doctors they know to draw to control the from the city But the other modalities they should learn it. It's not the same. Yeah, therefore the education of Colleges even the medical physicists. Yes, we know the anatomian physiology not only physics mathematics and electronics Anatomian physically I used to have my Anatomian physiology book in my in my bags because it is not actually the subject for us But we should master of the subject. Yeah, we know the language of medical doctors I cannot say please the tumor is just in the Backbone like this I talk about the anatomy with the medical doctor so long you are not serious with the anatomian physiology They do not talk with you and so you are just so therefore it is important to know the anatomian physiology Yes, most of the people forget the things is the mathematics and physics. It is my subject. No, no It is medical physics not the basic physics Well, you see here actually in these cases, you know everything and up to the Dosimetric verification and position. This is also very important. Yeah, I will explain next Our the positioning the passion here. This is very very important you have always Work with this tomography tomograph city Lineaxilators simulator and treatment planning the four are the main equipments and All the places the passion had exactly same position. Yes, you have When there is a position change then you have not correct Treatment so it is your duty It's a very very good duty to place the passion to a right position The next hour I will explain when you have a very good position with immobilization devices then you can reduce the boundary of PTV When you reduce the boundary of PTV a small PTV what you have done you have actually saved the healthy healthy Tissues and so You you do not damage the Passion you increase the dose so through the immobilization and position You can do a lot Don't think about only the very good algorithm and calculation and Everything dosimetry is every important, you know, I do not explain Dosimetry everything is but the positioning is very very when we forget sometimes we do not cooperate with the technician or Radition oncologist, please go and always think about the positioning you understand the whole chain So that you can understand this position is right or not and every time there is a Image and you compare with this maybe once in a week When you think it is more than you can do that for the positioning is very very important That is just important like the calculation and dosimetry and treatment plan so here is the objectives everybody knows destruction of tumor and little Effect and revival of tumor and this is actually the avoidance of treatment effect You know this treatment loss of function restriction of quality life.  It is not given in actually ICRO 50 or 60 or 62, but every medical physics all over the world use this table or similar table Because it is actually the limitation of tolerant doses is given in this and see here is the Different organ and how much this organ the organ at ricks is actually You irradiate one. So when you irradiate a Part of the organ you can increase the dose and when the limitation of dose is higher Then you have the easy tax to do the plan Yes, therefore actually this table is you give you the Criteria to save the different organs Yeah, it is actually from the imami and you can find all the literature I do not explain more when you have question I can go through the table And you see here actually also very important from the medical physicist of course the radiation oncologist you know in the there is some Orgon and serial organ and this is a parallel organ. Yes, and your case on serial organ like Spinal cold yeah, then it is actually your tax is very high your responsibility very I do not Do any burden in this serial organ then you actually the function is disorder But instead of that when a parallel organ just like a light here in this room I can choose one light because parallel connection for others, but when you have a Christmas Christmas light when you see one then everything is dark That's actually the series. Yeah, everybody knowing physics, especially electro techniques How this and it is not difficult sometimes to know in who is case is parallel who is case is actually serial but the medical oncologist and Pathologists they know they also take care about this, but you understand also very important because some hospital The medical physics is the draw also the contour also the organ at risk yes, they do Not the PTV it is done by the radical Radiation oncologist, but the medical faces they can prepare for the draw all the organ at risk and they come and they check it and Maybe they extend it. Maybe if there's some correction, but you can do the organ at risk And here actually what I'm telling The fixing of treatment position is the first case then the patient there and we fix the patient here This is very important and the fixing the patient. You know this place should be very compatible The passion lying may be 30 sitting or 40 sitting So maybe he's a good to come and and lie there So it is very important to ask discuss. What is his position? What is this actually compatible for him and you do that here the immobilization and then also the question is of this city It is a diagnostic city or are simulator city And then there is a diagnostic city that you have only so orientation and you do this different slices and later in the simulator you mark very good, but when Simulator city then we have here actually the mark here on everything because the medical doctors here fixed And not only the central plane, but also actually the iso center Here the fix the iso center when you go to the treatment planning and you see already There is a field. There is a just an arbitrary field with the iso center and you start to do it. You do not search any Iso center In the treatment planning is also given Therefore here is actually your decision your hospital have your hospital has a conventional city or Simulator city So these are the devices in next hour. I will explain little bit more These are many many devices. Yeah Sometimes there is a combi boat. You have heard maybe some hospital the people they supply you the combi boat and the combi boat You can do all the placement but here is a Many many things and actually here the technician they have the Entrance to Choice these things. Yeah, but I think it is a better Together with the team they Choice the all the apparatus. I have no many my colleagues Even do not know who is the where the immobilization in this room. They do not know I asked them Can you see your immobilization? Oh technician, please come please? I do not know in which place and they search everywhere. So don't do that You know actually the immobilization devices is very important Biggie of positioning So here the city You you can do the city when everybody knows in city Actually also quality control here in cities very important. You have a city phantom you send them and You also put the quality control whether whether the different organs the density is correct The contouring is correct. Everything should be also quality control from your hospital It is not the machine of the radio diagnostic. It is a part of the machine Belongs to your department in the physics department or radio therapy department so Here is also the process actually City we know the city is actually be important. Why city is important treatment planning? Can I explain here? Yes, because we want to get radiation So when there is a radiation properties there then you can get also But the other model to have no radiation absorption properties so we can also take aids help and draw the Therefore city is must and city is actually on this without city we could not Plan it is the three-dimensional. You can see in organ places and the density So you can calculate the treatment planning So it is actually the tools for medical physics city without city We do not need any medical thesis with the projection radiography, so the medical doctors do at the only older time with conventional conventional Treatment, you know this yeah, but it's still then when conventional treatment you can need city may be one a one Level and you can do that Yeah, we have we have always irradiated 3d Can you irradiate patient 2d? Never Yeah The radiation come 3d and we always irradiated 3d, but we cannot calculate the 3d That's why the problem at that time and we could not also conform because we have no tools No multi-nip like this, but we have irradiated always 3d Yeah, now we have the tools to calculate 3d and also in hardware To conform the tumor and other organ see here is the contouring. Yes, I explain and you see here the contouring and And you can start in case of larynx here Just the outer contour then target volume in this case PTV everybody will please I explain later The planning treatment volume it is actually where we Calculate an organ at risk in different places according to the need of the patient and So here is the strategy for the medical doctors Sometimes the draw and the tumor you have seen and the decrease the volume and again increase the dose and so they call it Do more detected and two more suspected you see here is the actually I have taken these slides from medical doctors I think it is very nice The medical tumor mass and tumor localization tumor character with model it is needed So it is a It is a actually long and very very positive development even in Germany I am actually the witness of all the development because I came there 72 and Started my radio therapy medical physics in 78 at that time. There is no computer No water phantom nothing We do everything with hands and everything so I know the development only at the time Even in the hospital when they the head of the department is not there and the second people they have different Treatment volume. Yeah, you cannot compare even in the hospital yourself to the head of the Rational oncologist and his second man. Now, there is a very very positive in between the ICRU. They are given the correct definition how you need it and How you record it and everything clear? So all over the world We have the same philosophy So we can compare and even we can compare the outcome. So it is a very very positive development So the people are thinking the radiation oncology and medical physics. They are always developing and developing and developing so you start is at 29 and Then ICRO 50, you know this one and you use it and Of course this 62 is also very important. Actually, we cannot download such types of ICRO. You should buy this one and It is a very expensive but you can copy from anywhere and You can ICRO 82. Yeah, when you have MRT then 82 Then you use it. So here, I do not explain the 29 It is actually the old at the same time. You have seen here at the time. They have also the reference point Yeah, these are all But here is important the ICRO 50 They have the GTV Then you have CTV and you have PTV and you know everybody I think so GTV actually with the Amazing modalities you can detect the tumor and then with the microscopic Then you close the microscopic with the amazing modality and then you have the CTV and then actually the PTV very important the margin from setup of geometric Uncertainty as organ movement the both are in closes. So I tell you earlier I talk to you earlier when you have a better immobilization devices Then you can actually decrease the setup uncertainty these are These are actually the contouring and you have also many many things here inside like reference point, how can you define difference point according to the field arrangement and You can also hear the normalization Optimization you can find here If you have some question, I don't know it is too quick Okay Because one hour Finish it this but you can some question maybe it's not So the next one you have here The the ICRO 62 it is actually the new is here. Then you have the ITV It is actually a part of PTV When you differentiate this then it is easy for you to minimize the setup That's why they're doing that. Yeah, it's more differentiated more easy to after that your decision to eliminate some uncertainties and what is yes This is the question. We do not actually Criticize them, but sometimes it is not Possible because some education. Yes, there's always the continuous education is important. I know also hospital They have never seen like this here. There's been a new group even they have their national protocol When the national protocol they not consider this international protocol, they do not do that So also the national protocol should do what is the ICRO is going but I know many many hospitals in Germany Maybe you have a Media of information, please ask them do that and even here the OAR There is in this protocol. They have also like this is like the PTV for OAR Another PTV in the older protocol. They have not PTV like Yes, this is also the organophorics. They have some boundary. So here you can consider the movement and setup accuracy And what is important here the conformity index? This is also very important for the 62 So here actually the summary for all the modality and In what is actually CTV, ITV and PTV? I think I think it is I have also taken from the IAEA No Yes, not not the Panambra and not the What is this? Buildup not the buildup reason So therefore when you have the eye view in a treatment planning that you put the boundary You put the boundary The field boundary is more than the More than the PTV so that the 95 percent cover the PTV Yes, that's why you place the different leaps is more than the PTV Here does not Not Panambra not a buildup. So you plan so that you have 95 percent in the PTV therefore your field is If your field is not equivalent not the same as PTV's boundary, it is Larger it is a linear accelerator. Don't don't think about Panambra. Yeah, it's not a gamma Cobalt-60 machine is a tiny point. So Panabra is very less. So it is not actually the problem. Yes Okay Here is actually the reality. Yes It's not like a round shape or overall shape. It is actually the reality. So I have taken also for the medical doctors This you can see they have written everything very well. It is actually the work of radiation oncologist So here then the beam modeling this tools is very very important everybody know where is in the preparation beam modeling in the TPS on the beginners you have already the physicist And here I have started the optimization criteria a field form you can you can fill form with this Satellite blocks or Here with the multi-leaf You see here the view form and very easy for the multi-leaf Coalimeters and it's not only the treatment conformal treatment But also the planning is very nice. Yeah at the time earlier time we have four leaves in always a rectangular order or Square you have no many many leaves. So it is easy to do that But the yeah, we say when the machine is very easy For the medical doctors and then very complex for the physicist. This is the vice versa Yes, so you when the medical doctor the machine is very simple then you have more more quality control. Yes, and Every country is a new roof. They have their quality control protocol. We are doing the take daily checks weekly checks Monthly checks three monthly checks And many many work is there and it should be also in Germany even Italy the control by the official every two years whether you have done everything or not so Actually developing country. I have always the I have always the experience in developing country the physics they think they think their work is to do the treatment planning it is not Yeah, your work is actually the quality control Yeah, medical doctor do not care whether you have the quality control or not. They care that you do the treatment planning So you do the treatment planning and you finished your work go at home So some countries they have no regulation at all for the quality control. So the medical physically do not do the quality control Yeah, this is actually They they harm their the harm their professions When they think that you are doing only the treatment planning Yes, so they they do not need any medical physicist They take the technician and they pay less This for them is easy So one times when you do not develop the quality control in a hospital actually you harm your profession Yeah, sometimes you are not there the technician is there Please do the treatment planning There are many co-recommendation in the IA even you come Professor for the one it may be from Italy and you you can deploy yourself don't think Like this. I have my treatment planning with medical doctor satisfied. I go at home don't do that Then you actually harmful to your profession in medical physics because you are something the people your place in the whole chain Nobody can that you can this the meeting. It is the quality control. So here the eye view as a beam form you can adjust the treatment volume like this and it is the conformal and Optimization of energy just you are telling your medical physicist, you know the actually the Parties of radiation.  So you can optimize the energy and Here is a Entry point. This is actually the daily things when there is a tumor here How the entry point look likes? Maybe here. Maybe this We need an wage or not on every your decision to choice of best angle And here you see the numbers and waiting Yeah, when you some high, you know Actually the head and neck tumor maybe sometimes in 14 or 15 fields In the direct planning So your decision always do optimization yourself. It takes long time to do a best configuration and Waiting you're changing changing changing easier for the IMRT, but in the 3d conformal just optimize yourself with your Experiences so sometimes they are a medical physicist in the hospital may be very specialized in the TPS and he can do earlier than you at the head of the Medical physics. So it is actually your experience Some hospital. They have some standard Standard tumor and they have some standard Mask they put it it and modify it. You know in this case I have four field box built and they put it this one and Then they can change it so you can do that also when here You have the optimization wages. Yeah, please use more dynamic ways Yes, because if the technician when hundred wages in the day Then it's not so easy Maybe in different angle the chains should be changes. So the dynamic wages is very important Some cases is not possible, but I think you use also the dynamic wages so here the Type of criteria I go later. Here the combination of electron and photon Yeah, you can select in which cases photon and electron and opposite field waste And here three fields and rotational irradiation in Germany. There is no rotational at all No rotational. They do not that it actually historically the rotational The insurance did not pay because I don't know one field So the medical doctor select more fields because I have more money and now is the tradition is so The do not use actually the rotational field, but we still many cases you need it Actually, I am RT. You know this rapid arc and like this but in 3d conventional rotational feet is very seldom Here a non-coplanar. Yeah, and sometimes in head and neck a uses, you know, this 3d coplanar a non-coplanar It is sometimes, you know, the actually the geometry and the fin configuration sometimes Not easy for the beginners, but when they do some plan then they understand What is the no coplanar they move their coach and the patient because the because the head of the Only in this direction not like a gamma tone at the time. They can also be like this direction So you place your coach in other directions So now is the criteria Here is the criteria from the IC RU. You see here Plus seven percent to minus five percent. It is actually the dose inside the PTB It should be maintained When sometimes it's not possible very complex then you consult with the medical doctors and he decided Maybe less than five percent Then sir, okay, I selected but not your decision. You try always as this is to do that And this is actually the condition for the PTB and organ of ricks the condition I give the once again this table. So in this table and this condition then you can fulfill the treatment plan so here actually Optimize the dose distribution when you have all are setting together then you can optimize you can normalize and you can put actually To gray in the IC RU Point and then you have the final check final plane like this It is only you know one one Level one level, but you have different so with the help of ice ice iso-dose you cannot judge this one. So there is a new methodology it is you know this This is called Dose volume histogram. So every pixel voxel, you have the dose and you see in which dose and then you draw the volume Will fulfill this condition against the dose you see here actually the PTB is very good Homogen and applied the dose and here is the other organ of ricks So you can judge very easily for medical doctors is very One minutes they can judge in which plane is better But at the older time when only one plane then I said is okay, but now is many many Scans and you cannot judge it And here actually the case I have drawn This is the ideal case, but is not realizing the practice when the PTB in 100% that is very good and actually the organ of ricks nothing Should I should I do this conformal maybe in brachytherapy or proton therapy, but it's not with the photon Electron Brachytherapy is more conformal. Yeah, you know the brachytherapy is very important. It takes again the renaissance In radio therapy it is it cost one-third of the surgery Yes in brachytherapy again one-third cost, you know from the surgery in brachytherapy one ninth is a very very cheap but The people are medical doctors sometimes not because sometimes in Varsity, so they know They need to touch the patient here. So it is extensive work But external beam is just like the beam is there. It is easy So I Suggest in developing country do more after loading. Yeah It's a very very important even some countries like India and China. They have very Manual after loading. Yeah, when the passion load is not so high then manual after loading is also very cheap Yeah, they have seen in India $1,000 there's a manual applicator for Service carcinoma it takes long time maybe 28 hours, but they are doing some health I have seen in also Africa in Tanzania They're doing like this. So it's possible But I suggest when the frequency of passion very high you have after loading remote after loading Hydro therapy And it's important. What is the radio therapy is also very? Radio therapy is also very human when you have a radio therapy there Then you have maybe in one day in the evening a one day in the afternoon Take it free for the poor people, but you can do it chemotherapy or surgery because chemotherapy everybody need the medicine But when one half days free for the poor people They have the aid of radio therapy So here three treatment planning other three treatment planning for the same patient I select it maybe this red one. That is the best one So here is different types of different types of the treatment planning everywhere you can possible the treatment planning and Here is a very good tools the DRR, you know from the from the projection radiography You can from the cities you made the projection Radiography when you have projection radiography, then you can compare with simulator at the same times in field control All the three can you compare when they are very very Concise then you have a best position So these tools is always you do that and send from TPS to the treatment planning system and the simulator Yes Please here here the all the DRR so Then when the DRR there you can simulate the patient once again when there is no city simulator normal simulator You can simulate and see whether the Positioning is okay, and the field control verification is everything, okay, and here's the information system Here you sent not only the treatment planning, but also the DRR here once again and then again positioning the passion in the linear accelerator room once again and Then you do a image field control Here this is actually the image for control with a piece Or some film pot inside the treatment planning room, and actually this is important the DRR simulation and verification when the three three boards all the three are Fit together then you have the best situation. So and then the radio therapy Here in the whole process you have the random uncertainty and the systematic uncertainties have here list of all the Uncertainties here is the list of all the uncertainties and it should be removed through different mechanism and through different prequations and We'll explain the next hour this whole the uncertainty how can we move it through the verification through the immobilization? Through the control of those and everything so that you can minimize All the uncertainties. So you have a very successful radio therapy what you can And what is important also for you? This is a park system and most of you they have the park system Achieve and you sent everything to there because in you know the all the documents on radio therapy you should Have for 30 years Here in Germany when somebody after 10 or 20 years come and maybe ask you have bad treatment for my grandfather So you should be you should actually prove it is it is everything is okay. So 30 years the Achieve you in the Radio therapy and 10 years for on x-ray diagnostic So here all the documents You send there some hospital have their own Packs for the radio therapy department. I suggest actually every radio threat department their own packs Otherwise, there is a central packs in the radiology department and you should have your place there And you have a good cooperation with the technician of the radiologist. Maybe you have your password to go there freely and control your data yes, so it is actually the matter of Organization, but I have a small Department with their own park system. It's also good. You can Care yourself But the pack system is very easy the one of the question the medical faces Yeah, your taxes very heavy actually. Yeah, when you have the pack system when the new system come You actually convert all the data from the old system to the new system Yeah, the vendor always throw no problem. We are doing this. We supply you the Software that one after the Sold it. Yes You cannot change this. I have sometimes is a band and now the DVD and we can read the old one So how can you preserve 30 years? So actually your duty to continuous check up the third 30 years Otherwise you are she bit and after that is you cannot read it So these are all the literatures. I have used of course my experience in hospital I have finished this Financial now your question or your comments Please do that Maybe we have two or three minutes Feel free and do that. Yeah, there is no foolish question only foolish answer Yes Actually I see TV 95% I see TV is the same to yes You have a documents then you have no response we do are going to the documents but do better than the document that is allowed about not Yeah, yeah, please Yes No, no Any question, please or anyway comments on three feel free Very short time we cover everything and here is the director Maybe in the interval we can discuss more details Yeah, you have free here. You are here. No family. No girlfriends. Nothing. You are here only to do the medical physics Yeah, thank you for your attention We'll see


The second talk. The second talk in this session is Locals Concentrant MVC, Combining DMR, and Obvious Transport by Kamheiji, Peter Shior, and you are also showing your access and your own role as a speaker. Thank you. So yeah, this is James Worm with a colleague from Miami University, Peter, who is also in the room. Yeah. So first I'm going to introduce voice MVC because maybe most of the people in the room are more interested in the Obvious Run stuff. So I will go smoothly from JAL Scramble Circuits to DMR, which is a multi-party version of JAL. And then I will speak about the results in our paper. First, we have a transformation from any MVC protocol or binary circuits to DMR Bravo Circuits, so we will continue in France. Then we realize also about some robustness property of this carving in DMR, and finally we have an instantiation of this compiler using the MVC. So multi-party computation, the classical example, is that you have this set of parties, they are millionaires, so who is the richest? So if we have some trusted party, this problem would be solved very easily because the parties just have to tell this trust person how much money they have, then when the trusted party has all of this, she can compute, though Alice is the richest here, she has built everybody. So here there are no problems at all, even if you have music-having parties because they are just outsourcing all this computation to the trusted party. But now the real world is sometimes not so nice, so when we don't have this trusted party we have some interactive algorithm, this is our MVC protocol, and now the problems we face is that, yeah, we have these malicious parties taking part in the MVC protocol, and they might not follow what you want them to. And the way we want to capture security is by saying that this is indistinguishable from the first case. So there are so many flavors of multi-party computation and this talk we will focus on Boolean circuits. We will also work on this offline online setting or pre-processing online setting, because the parties can use some correct randomness independent of inputs, you put all the heavy work there and once you have that you have a very efficient online phase. The adversarial is static which means that it's going to corrupt the parties at the beginning of the protocol, malicious which means that they can deviate however they want, and we assume also that it's always majority. Yeah, in this setting what we want to do is bounce and we want concrete efficiency. So if we start with the classic construction of Giao for two-party computation you have found some bof they have some inputs 1, 2 and they want to compute some circuit C on them. So Alice would gargle this circuit C this some encryption of the circuit which is going to send to bof then both parties are going to engage in this input encoding protocol both bits encoded inputs and with that he can evaluate the circuit and then just send back the result to Alice. So this is in the SEMS case and here what happens is that from these encoded inputs and the circuit both cannot learn about the inputs of Alice. Alice doesn't know anything about both inputs apart from the result of the computation. Now in BMR things are pretty similar the parties also are going to gargle some circuit together that they are going to encode their respective inputs private inputs and once they have this they can locally evaluate this gargle circuit that they have produced. Now we also have some problems if we compare with Giao. So in Giao we have just one party doing the gargle but this is not the case here we cannot trust any single party we are in this situation with this setting and we need to do these steps of gargling and encoding using an experimental MPC protocol and the good thing though is that we can gargle all of the gates in parallel so this is how we are going to get constant gargle. So that is the hardest step out of this gargle and input encoding the hard bit is how to gargle the gates and this is what we are going to focus on for the rest of the talk for the next minutes So these are the costs of gargling a single gate in BMR since it was proposed in 1990 so the first proposal was required a lot of zero edge proofs for some some random generators this then was a bit overlooked until 2015 when Lidl did the gargling using the speech protocol which required a linear number of modifications to gargle every gate then the year after in PCC with Lidl and SMART we have our paper doing the gargling using somewhat of an encryption we still have some overhead due to some zero edge proofs that we did for the ciphertext, so this was a quadratic overhead that is presently produced works now in this talk we just need to do a single modification in the underlying technical to gargle a gate we rely on the obvious transfer the external MPC protocol and we also achieve the VXR property I should say concurrent work by one runner-looting and cats presented in CCS is here they achieve similar results so starting smoothly how to gargle a gate with Lidl you have your truth table you have input wires U and V the parties are going to pick two random keys each wire then the encrypted truth table and permute the entries in BMR it is very similar the difference now is that basically we have n called keys of everything so instead of having two keys per wire we have two keys per party per wire we are going to do the same encrypted truth table but now instead of encrypting a single key we are encrypting n keys and we use n keys two n keys and each party knows a perfect keys for everyone once we have encryption we do the permutation so the encryption in BMR we are scared about if you want to encrypt one of the keys it is quite easy imagine you want to encrypt one of these entries so you want to encrypt one of the keys so if you want to encrypt the key for party J you are just going to mask it with this random value that you think with F and once you have encrypted one of the keys you have to encrypt the other so it is the same thing at times the good thing is that these PRFs can be computed outside of MPC world and then this becomes just a local operation you just have to do something, sorry so this is how you encrypt one of the entries and one thing to note about this is that this encryption is manipulative so if you look at it if you have the encryption of x here and you add some value y to it you get the encryption of x plus y and this is something that we are going to use for the traveling of a gate once you have your encryption of this key for value 0 we are going to add this product on the right so if you look at it you have some these are some bits on the right some secret permutation bits and you have those multiplied with some offset rj so this offset rj is what allows to have the freq sort property we define the keys for value 1 which would be the key for value 0 plus this offset and because of this that we showed before here we are going to get either the encryption of the key for value 0 if the bits on the right are 0 or the key for value 1 if that is set to 1 so how to grab a line of gates the parties are going to do some coin tossing to get these secret permutation bits once they have that they are going to compute the shares of the product that we are missing so these are bit bit products or bit stream products and once they have that and the encryption of the entries they can produce the garball gate and they can do this in parallel so bit more graphically the parties are going to use some multiplication in the Lightning BC protocol and then to do the bits in products they are going to use a correlated utility which is very efficient things there is some caveat here that we need to check consistency between these two smaller protocols so we need to make sure that the lambda values input to the correlated utility correspond to the ones but this is very efficient this is just some random combination of values and you can take the equals so yeah this is the first result this is transformation you get your favorite MPC protocol in F2 and now you can get constant problems by doing this the second result when we start proving this protocol we realize that BMR is actually quite robust and I am going to explain what I mean with robust now so the idea is that as we have all these copies of the keys of each party in the garbled circuit now if the adversary gives some input values in the circuit to a party and a party garbled the circuit send them to the adversary now we can let the adversary modify the circuit in any way he wants this in particular this modification we can capture as an additive error and now when the parties are going to evaluate the circuit they are either going to get the actual value or everything is going to result in an abort that also doesn't really get information about inputs so we are well safe and why is this the case well again if you think about this malleable encryption scheme that we had this error that the adversary can introduce can only change the output if it manages to switch the key so if I am going to party I am party jerry in order to cheat me you would have to guess my offset rj I already know it so this becomes negligible as long as R is long enough in previous works it was allowed to introduce these kind of errors in the gardening but not after seeing the carbon circuit also the reductions to the security the PRF were not very tight the whole circuit was required to be authenticated whereas in our case we just need to authenticate the smaller products third result we have is an instantiation of this gardening using 1080 so 1080 is a protocol a multi-party protocol for wind and circuits it was described in 2015 and it was also optimized recently in the concurrent work by one at all and the only thing you need to know about this is that in order to achieve marisi security they use this information ferretic max that looks like this so in order to authenticate the value x there is some key that has some values k and r where r is some global value and now we use this global value r of 1080 to be the offset that is required for Fritz we are basically solving two problems at the same time we get the active security of 1080 and the offset for Fritz we look at what we have before this is what we have for any MBC protocol for binary circuits now if we use 1080 we can basically drop all of these because we have it all right in between those people so basically one multiplication in 1080 is one global gain in the R going to the efficiency this is how it has evolved over the past years so speed CMR was something in 2015 and here when we say mascot BMR this hasn't been an actual work but you could think of doing the same thing as speed CMR but using the recent protocol of mascot which is like a more efficient part of speeds so the improvement of over the previous works was small but there was some improvement whereas now we are going basically from gigabytes to megabytes so this is the communication cost for covering the AS circuit and we have for free parties we need 15 megabytes for 10 with 67 and if you look at the most efficient wonder they would require almost 4 gigabytes for free parties or 55 for them in conclusion we have constant rounds for your favorite MVC protocol for current circuits also free the only overhead that you have is this correlated OTs so if you have a security parameter overhead if you are willing to use 1080 to get more efficiency it gets even better we have also improved the understanding of the security to the MR now we have this unauthenticated circuit that gives us a slightly better online phase and we can think of different open problems so can we further optimize the garb of the MR so as I said we have 10 copies of its key on a garbable entry so can we further reduce it because then it skates 4 times the number of parties in the parameter and also we have to build a quadratic number of PRF valuations to garbable which is not very bad for the ESNI on hardware but still doesn't do it maybe we would like to optimize how about tanyoti can we optimize tanyoti and then just wrap the improvement here or can we think of any other MVC protocol that for example exploits the parallelism we have on garbable MR can we design some efficient activity security protocol to do this that's it on my side I will take any questions thank you we have plenty thanks see you again


You know what's funny? I've made a lot of videos about games on the eShop worth buying and probably too many videos because I'm out of games. I've talked about them all already. I'm gonna have to look to the future. This video is filled with fun, exciting games coming to the eShop really soon. Some in just a week or so. Last weekend I went to PAX with my wife Kim and a bunch of my friends and we got to a hands-on experience with all of these games and they're so good. If you've seen my eShop series it's gonna be just like that but I'm gonna splice in a bunch of vlogging and fun that I had at PAX around each of the games that I talk about today. So this is 10 eShop games coming to Switch really soon. Actually I'm lying. It's more like 13 or 14 games. 10 just sounded better for the title but I played so much. I have so much to talk about.  I've never been to PAX East before. It is a giant convention in Boston filled with video games, indie teams, things to buy. I'm very excited. It's about a six hour drive for Kim and I. So we gotta get going early if we want to get there in time to pick up our badges. We are officially in Massachusetts. Okay we're finally in Boston and we meet up with Scoot and Fried Biscuits first. I can't wait to meet some of my favorite friends here. All right that's it. Cut. Thank you. Appreciate it. Thank you. Oh my god. Oh my god. Scootish from Twitch.tv forward slash Scootish. Wolfden. All right. Hey bingo. We gotta go get our badges before it's too late. We got like half an hour. All right and then as we're walking to PAX who do we see already walking back from PAX on the other side of the street? It's Bob and Hannah and they were also filming so it was like a double film exception from across the street. We were just going to PAX to pick up our badges. I didn't think we were going to see anything of the actual show floor but right at the front they had the Zelda Tears of the Kingdom display. Going in to PAX Nintendo said they weren't bringing anything Zelda related so just the fact that this was here was still really cool to see. I don't think I really have to tell you guys about Tears of the Kingdom. We're obviously all super excited for this to release. As soon as it drops I'm going to be live streaming it on Twitch. Probably my entire playthrough. Obviously one of the most exciting games of my life but we're here to focus on these cute indie gems coming to the eShop. So PAX is closed but we can take a look out into the empty venue and it is massive and it's just filled with these booths and games and lights. It looks insane. I haven't mentioned this yet but Kim and I've been battling a lot of anxiety and as I study I was just imagining the amount of people that might be on the floor. That didn't sit well with me but the actual sight of everything there itself was really cool. Okay it's day one and it's very packed and the fact that we're even attempting this I'm proud of us. It's packed. It's packed. I was trying to be sweet. I thought that's a joke and she made a joke. All right we've got a signing in half an hour. Let's get down there. Bob and I had to go and do a fan signing which was a ton of fun. We were stood there for like an hour and a half meeting so many people. It was technically a non-tendo fan signing although the sign did say wolf den slash non-tendo. Maybe I was just crashing his signing. I'm not sure what happened but it was so much fun getting to meet some of you guys. This whole weekend was a blast meeting people. But anyway finally our first game I beelined to one of the ones I wanted to play so badly and that was Rift of the Necro Dancer. That is the same team behind Crypt of the Necro Dancer and they even bought a huge add-on pack called Crypt of the Necro Dancer Syn... Syn... Syn... Synchrony? Am I pronouncing that correctly? So Rift is a spin-off of the Necro Dancer games which those games are notorious for their incredible soundtracks and kick-ass music. Many of us played Cadence of Hyrule and that's the same team. In fact it's a spin-off of Crypt of the Necro Dancer just reskinned with Zelda. Rift changes up the rhythm game genre and heads to a classic guitar hero-esque format and at first glance I wondered what was going to make this one special and stand out from the crowd. But right as I started playing suddenly all the pieces started to fall into place. Pun not intended because that's kind of what you do in the game. Because you don't just hit notes and beats on the timeline like you would a Katara game but you're actually attacking enemies and sometimes enemies will have extra health which makes them go back up the timeline and you need to hit them again and different enemy types behave differently. Bats will not only go back up the timeline but they'll flutter side to side quickly or skeletons will dance their little butts back up the way of the timeline. So this makes the gameplay really frantic with quick and sudden changes to the way you thought you would have to play the song but it all lands perfectly on the beat with the incredible music. It also gives me warrior wear vibes in that after each traditional battle there are rhythm-based mini games like yoga stretching or dodging attacks in a boss battle style. I had a lot of fun playing this one and I look forward to it releasing as well as the Crypt of the Necro Dancer DLC. Also while I was at their booth I went ahead and grabbed a little cadence figurine. They were like 20 bucks each. Look at this. It was like 20 bucks. It's so cool. But moving on right next to this little group of games there was one I have been dying to get my hands on and that's Wrestle Quest. I love RBGs but I'm also a massive wrestling fan. Here's a picture with me and Ethan Page from AEW. We're friends. I could message him right now and say hey you don't believe me? I said so how are you doing? Everything good? We'll say how long it takes him to reply. Anyway, Wrestle Quest. I've been keeping tabs on this one for a while. I've even been putting it in my upcoming Switch Game videos because I've been so excited. I was lucky enough to play this one at PAX with the developer watching over my shoulder. No pressure. Took like two seconds. We're besties. What I loved most about my time playing was the turn-based combat within the ring. It's a wrestle-fied JRPG but then the really nice feedback loop of using wrestling to solve one of the problems with JRPG design that you have to solve and overcome which is first order optimal strategies. As much as you have to pick the performant move you also have to put on a good show and use good variety otherwise you start getting penalized or you don't get the buffs and stuff like that. I mean you shouldn't just spam the same move over and over because just like if you're watching Adam Cole versus Kenny Omega it wouldn't be very interesting if Adam Cole just kept lowering the boom the whole match while Kenny Omega kept trying to hit the one wicking angel again and again and again and again. Although honestly that might actually be interesting. I would watch that. I would still watch that. I liked that once I selected a move I had an extra option of hitting another one if the opponent bounced off the ropes. At that point it's all done with quick time button presses and that really helps the match feel like it's flowing. There's tag teams, taunts, learning new moves of course, unlocking more wrestlers to fight with you. You can even explore outside the ring too which gives me a lot of Stardew Valley vibes with its art style. I love the art style, it's very Stardew-esque. Thank you. It's gone through like some iteration over time. The original spec for it was actually a retro project like very literally going to be on a SNES cartridge. Yeah I don't even know if we could fit the main character on a SNES cartridge now with the number of sprites that he has. With it being such a long game I'm sure there is a lot to do and so much more to explore. Would you say it's a game that anyone can play or just wrestlers can play? We've had the feedback from JRPG fans saying that they're checking out wrestling now and also wrestling fans saying that this was their first JRPG and they're checking it out now. Wow that's really cool I love that. They even allowed me to step in the wrestling ring that they had brought. This was a real wrestling ring that wrestlers were wrestling in through the weekend. I don't know what I'm supposed to do now. I just got in. I got to stand in there and wave a title around. I really regretted wearing what essentially was a prop top because every time I lifted my arms up you'd see my belly button felt a little risqué but it was fine. I had a good time. As Kim and I were walking around looking for the next games to play we started on the fan gamer booth. I love a lot of fan gamer stuff. A lot of special edition Switch games get released via fan gamer and here we had to buy this plushed bonga from Bug Snacks. It was a game that Kim and I played together and we adored it a lot. Alright but after that we turned a corner and we found two games. We actually found the Chucklefish booth and I love their games. They made Eastwood which I reviewed and I love that but they have here Wargroove 2 and Wild Frost. So Wargroove took the Switch by storm when it released in 2019. It's similar to games like Advanced Wars and the Fire Emblem series. It even won awards for best strategy game and in general was received extremely positively. I love the pixel art style, the multiplayer pvp, the co-op modes, even the campaign editing tool. This time around looks like we got Pirates and a Kraken. Then Wild Frost. I've had my eye on this Wild Frost game for a while. I love card games. I'll play any kind of card game. It looks really fun. It reminds me of Grindstone but I don't think they're related at all. I've been trying to play this all this weekend but there's been people on it the whole time but I gotta talk about it anyway. It releases in like a week or something and it looks really good. I love the art style and you guys know I'm a sucker for a good card game.  You don't want to know about it. Wild Frost is a tactical roguelike deck builder where you battle your way up a mountain while building the strongest deck possible. If you've played a roguelike before you know that means if you lose you have to start again but you can use any of your rewards you earn on your run to build a stronger deck and try again and I got a really good feeling about this one. Okay so while we're walking around the PAX floor I got a tweet pop on my phone from one of my other best friends, Donkey. Okay I don't actually know Donkey but he tweeted that he was at PAX and he brought his game Animal Well. So of course I wanted to play that. It's Big Mode's first game. I also wanted to try and make Donkey so we scurried over there. Animal Well is a 2D platformer metroidvania with a dense interconnected labyrinth to explore. So yeah what really impressed me was the game didn't need constant pop-up tutorial screens or how to play guides. It was just intuitive and confident in its own game design which reminds me a lot of classic Nintendo games. The small details like light bouncing off of moving platforms or the way water droplets impact with the wells of water it really makes the game stand out visually. But yeah I didn't get to play it for too long mostly because I didn't want to take up space on too many of these games for too long but also because people started saying, it's Donkey, Donkey's over there. And I like peered over the top of the monitor and I was like oh gotta go see him. That said uh not much was said. Donkey is a man of very few words. So when's the game coming out? The game is coming out uh winter. Okay. This is the greatest game ever created. This is the only video game that you should ever play again. And then looked at me blankly kind of panicked. Told him I was a big fan. I do actually want to talk to you. I'm a big fan. So I actually have a huge fan. I've been watching your channel for a long time now. And if you're watching this donkey for the third time I'm a big fan. There's one more game that I'm scheduled in to play for Friday. It's just not at PAX itself. It's across the street in a hotel which when I found that out seemed very sketchy but Bob told me this is something that happens all the time where a lot of these indie teams are kind of flawed actual floor space. So they just rent out like a big suite in a hotel across the street and they set up there. So to make sure that I didn't get moided Kim Scoot and Biscuits came with me and we all went up to play Bread and Fred. Bread and Fred was a heavily talked about game leading up to the weekend at least with my group of friends. We all wanted to make sure we played it as it just looks like one of those games that will blow up on Twitch and YouTube when it releases. It's a two player game where you play as two penguins bound together by a very short rope. You need to work together to climb up a mountain by coordinating jumps swinging each other grappling walls and more. All right what do we do now? It is incredibly frustrating in a way that is intended and in a way I don't know if I would be able to handle for a full playthrough. But that is the point of this game. How would you describe the game to somebody that wants to play it? So do you know gameplay getting over it or jumping? Yes. So that one small slip up can cost you a lot of progress as you fall slip and slide all the way back to where you started. I think I made it a little bit more frustrating than it would have been normally is having the guy that made the game over your shoulder laughing at you constantly every time you mess up. I'm glad they were having a good time.  It actually looked a lot harder than trying to do it with two people but it was pretty funny. Making us feel very inferior when we were done he even showed us on his phone a clip of a speed runner. It was insane. It was one guy two controllers controlling both penguins. I don't even understand how the speedrunning community figures this stuff out. It's close to how we were playing. That is almost the same. It took one guy literally seconds to do something that was going to take scooter night hours. Okay I like there is one more thing we did on the show floor. We went to the Devolver digital booth which was insane. The backside of it was a full cathedral cult of the lamb candles everywhere. It was incredible. There's cult of the lamb DLC coming as well. I didn't get to play that but I love the game. I watched some gameplay of it. The other side of their booth was like an old 1950s movie theater where they were selling merch. It just looked so cool. I love the guys over there at Devolver digital. I've been working with them for a long time doing the eShop reviews and a bunch of other stuff and I even got to meet Clara, the head of PR, who gives me a lot of the codes for the games. I've been working with her for years now. Oh and then Kim and I saw Last of Us PC and that looked pretty cool. But anyway bedtime. They say Boston is the city of opportunity and today I'm creating my own. Watch this. Call that the flippy dippy. Day two baby. Okay day two Saturday. The crowds weren't too bad day one on Friday I guess because a lot of people might have been at work. Saturday people have the day off work and it was busy. When Kim and I first walked down to the floor almost immediately we had to take a step out and our anxiety bubbled over a little bit. We needed to have a breather but fortunately after the first breather we took we kind of just calmed down and then we loud right back in and we played so many games. The first one was My Time at Sandrock. My Time at Sandrock is the second game in the My Time series with the first being My Time at Porsche or Portia. I can't say words and that game was a fairly popular switch release. They're both sandbox simulation RPGs and they remind me of like a 3D Stardew Valley. They have farming, building, romanceable characters, you know that stuff. Stardew Valley stuff. Sandrock takes place on a map 40% larger than Porsche and looks to dive even deeper into the mechanics that made Porsche so popular but I didn't actually get to play My Time at Sandrock so I can't tell you much about it. The demo that they set up here was this weird in-game event. I had to scurry around and try and pick up presents falling from a blimp before other NPC characters got them. The idea was cool because when I picked up enough presents he gave me a real life stamp on a real life piece of paper and said take this to blah blah blah and you'll get a prize and I was like that's cool. Never found out where I was supposed to take the piece of paper and I never actually got to play the game. Just this weird event so I can't tell you much about it but um it's a thing. Speaking of games I didn't get to play, the same area had a ton of games that only had one stall each and I just couldn't find time to get on them but man there was one called Extremely Powerful Capybaras which I hope comes to switch because it looks like a multiplayer version of Vampire Survivors and it just looks really cute and fun and then the other ones in this area were like Goodbye World, the Courier, Blade Assault and then Gory, Cuddly Carnage. I wanted to try and sneak in here but there was a kid playing for like forever. I will say though this little guy was cracked at the game. He was making the gameplay footage look really sick and at least that I appreciated while I was filming. I don't want to talk about this game anyway because you'll see why it looks wild. I'm actually shocked that this one's coming to the Switch because visually it looks a little too impressive for the console especially with how fast-paced the action is. I would call this one a hack and slash but the devs are calling it a skate and slash where you play as an adorable murder cat in a world of extreme toys and cute corruption with loads of blood dismemberment glitter and fur. Are you convinced yet? Because I am. The world design is sick. It's like a cyberpunk apocalyptic. It's hard not to get stray vibes off of it too but that could also just be the fact that you're playing as a cat. Even the music in the trailer slaps and the gameplay damn it. Hack and slash is my favorite genre of game and you're adding a kitty into the mix? I mean my wallet is upstairs otherwise I would be pulling it out for a gag right now. And then Kim and I got some cherry shaved ice. I know it's not a video game but it tasted good and I wanted to let you know about it. You know it's funny Bob and I spent all of Friday morning at the Toxic Crusaders booth because that's where our signing was. This game's being published and developed by our YouTube MCN. This is like the people we work with and they're making a Toxic Crusaders game and we never got to play it because it was so packed. But thankfully a benefit of working with them so closely is they just sent me the game so I can still talk about it. So initially Toxic Crusaders was a Game Boy beat em up shoot em up game based on the cartoon series by the same name. But recently RetroWare managed to acquire the rights to the franchise and wanted to bring back the beat em up in a bright colorful and fun way and I gotta tell you that theme song is really catchy. After having to sit for an hour and a half during a signing and listen to it loop on repeat it is stuck in my brain. Help. There's seven playable characters and you can have four players beating their way through the streets at once. If you enjoyed the recently released TMNT Shredders revenge you'll probably know what you're in for here and love it just as much. Each character has their own unique moves and powers. There's comic book cutscenes featuring the voices of Team 4 Star and visually it looks right at home on an old 90s arcade machine. While we're talking about games that were on the floor that we didn't get to play but the dev was nice enough to send us the game and after the fact so I could play this one at home too, Elsie. So Elsie is actually Gerard the completionist's game. We did have him on our Nintendo podcast episode recently which was easily my favorite episode of the podcast we've ever done but anyway we talked about his game. Gerard described the game as dead sales meets Mega Man but I'd also throw in risk of rain just because of the insane amount of items and abilities you can get and stack. It's a rogue like and as you platform around destroying enemies you pick up more and more items and weapons and abilities and also you level up as you play so you can upgrade your abilities even further. At the top of your screen you'll see all the upgrades and items you've stacked and just like risk of rain it can start getting really crazy as you soup yourself up to insane levels. I also appreciate there's a parry button which lets you skip damage altogether and you can even parry while dashing if you want to dash through attacks or hazards. I'm looking forward to seeing this game finished. So quick story the Mario van they made the Mario van and now it's here at PAX and we got to go see it and the keys were in it and Scoot and I tried to open the door and we had a moment where we were like we could steal the Mario van right now. The keys are in the ignition. We're thieving we could literally just and then my standout of the weekend was Mina the Hollower. I had Celia from Yacht Club Games talking me through this one and watching over my shoulder and laughing at my failures. Celia and I have also been friends for a while. She's been on my podcast twice now talking about upcoming games like this one and it was just again awesome to meet someone that I've been working with online for so long especially in like the indie space. I had so much fun coming here and hanging out with everybody. It was so good. Sorry for the tangent. You guys have probably heard of this one already especially if you love Hollow Knight. It's Yacht Club Games next big project. So Mina the Hollower is our love letter to the Game Boy Color. It's a top down action adventure that takes inspiration for some of our favorite games like Castlevania, Bloodborne and Link's Awakening. They've really meshed all of that together in a way that really it does feel like the brainchild of all three. So for Zelda I would say it does have like similarities like when exploring the hub doing side quests and exploring the village but the combat is definitely going to be more of Castlevania and Bloodborne so you will have to strategize. You will have to make enemies aggro.  Okay for me when I think of Game Boy games I don't often think of big expansive worlds but that was the feeling I was getting while playing Mina. There are a ton of secrets around the levels and Celia kept guiding me towards them which was nice. You should try following down and see what happens. Whoa. Oh my god. You want to try something else too? Hit that wall right there. Left right there. Whoa. Oh my god. I know right? Like I you know we made it or something. Oh and Celia even told us that Switch is getting a physical release so that's some fantastic news because a lot of these indies are usually only digital but not Mina we're getting a full physical. Oh so I found Bob's clone and it was just some really nice guy who I legitimately thought was Bob as he walked past but I took a photo with him and I posted it on Twitter and like no one even realized for a long time until I revealed the truth that it wasn't actually Bob. Then I got a photo with him and Bob. It was fake Bob. It was Bob. Bob clone Bob 2. Bizarro Bob. I also didn't mention this but the first thing we actually did at Pax on day one was walk down to this booth that was selling these big mystery boxes and I spent $200 buying three mystery boxes two Zelda ones and a supernatural one for Kim. I didn't know they were going to be that expensive otherwise I would not have even got anyone near the register. We opened two of them in the hotel room and they were awful. All right we got a we got a we got something got a blankie. It's a full-size blankie. A very blurry, scratchy, smells like shoes blankie. We got a pin. I see a water bottle. Kim's excited for what is easily the lightest water bottle I have ever felt. I don't know why he's got to be mean to him. You haven't even seen him yet. Awful? Okay. A little bum bag. No. No. That is very cheap. This has definitely been a really bad idea and then the window showed this which I could already tell was horribly printed and then a book. Yeah this is fine. I have no problem with this because actually this actually feels quality. This was $60. Yeah I don't know what you did that for.  Yeah I do. So it's it's three makeup bags. Just three bags? Oh my god we were robbed. It was that bad and cheap and knockoff and awful. I didn't get to open this one because it was in Bob's room all weekend because I put it on the podcast set that we had made and I wanted to open it now. This is the Breath of the Wild Zelda Collectors box. Okay this one has a drink thing. Okay this isn't even real wood. This is plastic. If this was leather and this was wood this would be sick. Then we have a bento style snack box. Champions pin set. We've got some Zelda stickers. Yeah this one's actually okay. Oh this journal is pretty nice too. This one's definitely the best out of all like the other ones are gone. We threw the other ones away. So my $200 of value is dependent on this box right now. This is actually yeah this is like fake leather but it is actually very leathery. Yeah this is nice. This is a nice little book actually. Oh we got a pen to write in the book with and then I think the last thing is like a satchel. It feels a bit cheap but it's big and it's honestly better than any of the other bags that came with the other one. Is it worth 65-ish dollars? Heck no. But at least there's something of value in it. Okay I just need to know was there any games at packs that you saw that you... There was the dog one. Oh no not puppy. Oh my god. Puppy can you hop down please? At least say hello to everybody. Hello. And I love the dog one. I'm actually remembering just now I wanted to talk about paparazzi. Can you kind of like explain it a little? You go around and you take pictures of the dogs but the dogs they don't really walk so much as they like south park character bounce across this. That's nice. It is fun and like the different areas have like different dogs do it because one area like all the dogs are on scooters. Do you get points for taking pictures of the dogs? Yeah but there's like special missions.    Okay that's it thank you. You wanna ask Big D what she would play? No because she wasn't there. She would play paparazzi. This weekend was so much fun. Got to play so many fun games and show you guys these games that were coming. But something I didn't really get to talk about too much is we did go all together as a big group. It was really awesome. Me, Kim, Bob, Hannah, Scoot, Fried Biscuits, E, we all went and one of my favorite memories of the whole weekend was Thursday night. We had all just driven and flown and trained in but we wanted to hang out and play some Valorant. I don't talk about this much on YouTube. If you watch me on Twitch you know about it but we all play Valorant very often and we all walked over to PAX and we lined up on their crappy little setups. They weren't too bad but it was tough adjusting to them. The headphones definitely sucked. We couldn't hear a thing. We were all lined up there playing some Valorant and we lost. But it was still just a nice time you know leading up to the weekend struggling with that anxiety. Kim and I didn't think we could sit on a massive show floor like that and just play games and feel relaxed but we did and it was a really fun time and I appreciate my friends but I also appreciate all of you and I appreciate all of the indie teams that brought their games out. I'm sorry I didn't get to play all of them. I feel like I played a lot and I got to meet some really cool people and I got to tell you talking about these indies reviewing them and getting excited for them is one of my favorite things that I do here on YouTube and with my career in general. Thank you for watching the video and I'm going to go back to PAX next year. Okay bye. Play the games, buy the games, wish list the games. They're probably also all definitely on Steam if you want to play them on your Steam Deck. I'm getting dragged out of here by myself. Okay bye. See you. Bye.
