 All right. Hello, everybody. Welcome to the Hyperledger special interest group for healthcare. My name is Ray Dogum. I'm the chair of this group and typically we talk about industry updates, developments, anything that's related to healthcare and blockchain and also for Hyperledger as well. So welcome. If there's anybody on here who's new and would like to introduce themselves, I would just like to remind you that the recordings here are posted on YouTube. So be careful what you say, I guess, especially if it's related to anything confidential from your company. Would anyone like to introduce themselves today? Does anyone have any announcements for the membership here related to the last few weeks or any job openings or questions, any interests? What would you like to get out of this? Okay. In that case, I'm going to dive into the upcoming events for this month next month and the rest of the year. So in August 29th in Stanford, there's the science of blockchain event. You can access that here. And by the way, this agenda is posted for everyone. It is a public agenda. And it's also posted in the YouTube description so you can find that link there. An important event actually coming up is the 2022 Hyperledger Global Forum. And we do have a discount code if you are interested in attending. It is on September 12th through the 14th. There are a number of different panels, keynotes, discussions that are happening, and a few of them are related to healthcare as well. I just pointed them out here. The health 3.0, how a DeFi-enabled tokenized data economy will reinvent healthcare and put patients first. That's one event by Heather Flannery from Equidium Health. There's a demo called Achieving Pharma Supply Chain Resilience with Blockchain with Daniel Leverick and Zoolog from Zoolog Pharma. There's a panel discussion called Best Practices from Leading Healthcare and Life Sciences Blockchain Production Deployments and Advanced Research Investigations with Sophia Lopez, Eddo Kyle Culver from Synaptic Health Alliance and Flora Nanda from Pfizer as well as Alan Bachman from CVS. So that should be a really interesting one. Is anyone here planning to attend the conference, the Hyperledger Global Forum next month? It's closed by me, but unfortunately I'm in another engagement at the moment and I can't get the time off, which is a shame because there's a few of those plus some of the other events I'd have liked to go into. Thanks, Sid, for sharing that. Is it live? I know stuff is put up on the Hyperledger channel afterwards. There's no live non-in-person option is there or is there some of these? I think there might be a live option for attendees. I'll have a look again and I can check afterwards. Sure, yeah, and that's a good question next time. Next meeting, I can, if there is a link or if they are planning to livestream it, I can let the team, I'll let the membership know as well. Cool, cool, thanks. Yeah, thanks for asking. September 15th, the Converge to X Symposium in Austin, Texas will also be going on. This is a pretty good event as well. I think this is like the 5th, 4th or 5th year that they're doing, 6th year here. So definitely check that out, especially if you're in Texas, Austin. September 23rd and 24th, the D-Side Boston group is getting together for an event as well in Boston. That should be an interesting one. On November 13th through the 16th, there's a health event, HLTH. Health, I think this is H-T-L-H 2022, so you can check that out. HLTH, yeah. Okay. Any other events people are looking forward to going to? They wanted to include on this list? Yes, hello Ray. This is Wendy Charles. I wanted to add that the Government Blockchain Association is hosting a conference in Washington, D.C. at the end of September, September 29 and 30. And it's about blockchain and infrastructure, so mainly like enterprise level implementations. And the goal is for to discuss building blockchain for government. And like many of our friends will be attending and speaking and happy to see Heather Flannery and Frank Ricotta on a panel together to share updates. Excellent. Thanks for sharing that in the chat as well. Appreciate that. Oh, sorry that I was scurrying. My camera was covered. Good morning everyone. Hey, Wendy. Good to see you. All right. Jumping into industry news articles and interesting projects. These are a few articles I did find over the last couple of weeks. If there are others that you would like to share as well, just add them into the chat and we can discuss them too. The first one here is from Vice News titled Tiktok's parent company bought a bunch of hospitals for one and a half billion dollars. I thought this was pretty interesting because as we know, Tiktok has grown significantly in the last few years and has created a cultural phenomenon really with video short video. So for them to purchase hospitals, I thought was a little surprising, especially this many hospitals. This is apparently the biggest deal, a biggest purchase made since Beijing's anti-monopoly crackdown on tech companies. As you may know, the parent company is called Byte Dance. They have full ownership of the women's and children's hospitals and cities from Beijing to Shenzhen. Bloomberg reported. So, I don't know how this will impact their business model or what they plan to do with it. It's interesting to see a lot of tech companies. It's not just Tiktok, but Amazon and other tech companies are really getting to the healthcare space. It's a short article, but I just wanted to bring this up. Any thoughts on this one? And I don't know if they're working on any blockchain developments or protocols, but I wouldn't be surprised if they one day talk about that. Here on a SOFO security blog, I saw that Slack admits to leaking hashed passwords for five years. I thought this was quite alarming. Slack, so from 2017 to 2022, Slack said that the data sent to the recipients of invitations included the senders hashed password. So here, just let me take a step back and say the company admitted that it had inadvertently been oversharing personal data when users shared, when users created or revoked a shared invitation link for their workspaces. So as part of that, their senders hashed password was also sent. So it goes into what went wrong here. Slack's security advisory doesn't explain the breach very clearly saying merely that password was not visible to any Slack clients, discovering it required actively monitoring encrypted network traffic coming from Slack's servers. So it goes into the detail of what happened here, technically speaking. Have any of you used Slack before? Wendy, I think all of us have from some capacity or another video, but don't you share your experiences? I think Sid was talking. But yes, I would agree. I think many of us in the corporate world as well as for personal use have used Slack. That's why I thought this article was quite alarming. Especially if you reuse your passwords, that's especially foreign to use different passwords for different applications so that if it were to be leaked, you wouldn't be in be compromised for other accounts as well. Yeah, they sort of actively went out and if you use one of these password links, which is one of my alls I had done, they actively went out and said if you use one of these, there's a threat that's been discovered. This is how to do it. So yeah, no, it's a good one to highlight for sure. Absolutely. You know, and here was hacked. Moving on to the next article here. This is from Tech Republic building the future of healthcare in the metaverse published actually a couple days ago. So they discuss everything from article artificial intelligence to augmented reality and virtual reality and how the metaverse will evolve, including that, you know, they predict by 2030 the healthcare metaverse market will grow by 48% Kager CAGR and be worth 5.37 billion dollars. I also mentioned that many companies are driving this innovation and change, including brain lab, an override GE healthcare Siemens health and years meta platforms incorporated and video Microsoft Roblox, a game change VR and others. So certainly major companies are working on developing the future for the metaverse. They talk about how mental health is an important use case in the metaverse. And specifically they say here. This is a interesting statistics statistically more than 800,000 people kill themselves each year in the world and 45,000 of those individuals are in the US. So comparably the high percentage of veteran suicides remains unacceptable with over 6000 veteran suicides in 2019. So this company to be 3D is migrating its telehealth platforms into VR into this VR medical environment. So this is just one example of a company doing metaverse innovation. There are other examples here as well. And, you know, I think that what's interesting here is also the quality of metaverses, so many people are really working on so. And when I say quality, I mean, the visual quality, the, the graphics, the pixelation. Because companies like unity and unreal engine and these are gaming platforms. These are, these have been used for in a hardcore gamers are gaming development. So what that means is the reality of VR is becoming more and more high definition. So, and I think that will drive adoption eventually because one of the, you know, one of the challenges for VR is that the quality is not really great so it like becomes difficult to use after a while, you know, you can only last 1520 minutes in those glasses but once they improve that I think it'll, it'll change the way people adopt it. Any thoughts on that. Yes, Wendy, I just had. Well, I think it's, it's great progress. A big question I have is about licensing of healthcare providers. Do any of you know whether how they manage licensing of healthcare providers in this virtual environment and whether they an individual must declare which state they are currently residing in. And it's great, you know, to develop counseling and different interventions for people who are in need. I was just curious as to how some of the current licensing laws applied. That's a great question Wendy. And it's also similar with telehealth as well in terms of like provider licensing right. Yeah, I don't know if there's been. Anyone on the call now. I'm not sure. And I'm sure they'll have to figure that out as well but Yeah, for some of the earliest metaverse platforms, such as second life, which is one of the first, they actually had a license and a licensed clinic. And each individual to declare which state they were residing in and they're they have therapists that were licensed in many states but treat people from certain states. I would hope that as states are entering licensing compacts that there could be more progress and making like mental health services and certain types of therapy services available without. I was going to say such stringent licensing constraints but of course we want qualified people but I just wasn't sure how it's managed. Yeah and I, you know, I do recognize that after COVID things kind of changed significantly with licensing for providers. And I think it's gotten easier to get licensed in various states. However, it's still a 50 state system in the United States at least. And the idea here is the patient can only be treated by a physician in which they're currently in so if a patient isn't, you know, Florida, they have to be seen by a physician who is a Florida license provider. And of course in the metaverse it's kind of different it's kind of strange because you can be anywhere. So it's a fair point. Let's take a look at for that. It also says here blockchain technology is recognized for its security potential. The blockchain is decentralized and data is not uploaded to a server or stored in a single location. Data in the blockchain also moves through several computers or nodes is encrypted and validated and is extremely hard to hack because all computers or nodes on the network must be breached simultaneously for the data to be compromised. Interesting article, very, very high level, but fair enough. Yeah, I'm going to move on from that one but I thought that was interesting to highlight. Just, just on that one way there was a, there was a, I think Oxford teamed up with the NHS in in the UK to do a sort of VR so not quite, not the metaverse but still VR for people with psychosis I dug up the link. If it's of interest. Thanks for sharing that game changer VR. Thanks for sharing that. Yeah, that's right. Yeah, but this is certainly an important space so I think there's first time I've seen this this is really cool. And obviously there's just a UK one so it's probably why you might pass by. It's fair enough. But they have done some studies on it so that's really great to see. Yeah, thanks for sharing this all included in the comments as well for anyone who's interested. Cool. And maybe one day we'll all be joining meetings through VR right that's kind of the promise behind the metaverse as well. So, engaging working environment, when we're all remote. Okay, this was an article from Politico titled artificial intelligence was supposed to transform healthcare. It hasn't rather lengthy, but I just wanted to highlight a few like grabs that I thought were interesting. So, this one is about AI funding and healthcare and how it's grown significantly, especially over the last few years here in 2021 there was $10 billion funded for digital health startups that were using AI. And 2022 is not over yet. So that's subject to change here, but it doesn't seem that it'll exceed last year's we'll see. And the FDA here it says the FDA has taken steps to develop a model for evaluating AI, but it is still an early it is still in its early days. So, to be to be seen how that evolves. The interesting thing here is that's highlighting that the AI enabled companies are becoming a larger share of digital health funding overall. So, about 35 30% of all digital health funding is going to AI enabled companies. That's pretty significant I think talks about different use cases using AI and examples here, including one from, you know, using AI and radiology at NYU, Lango and health, some of the challenges for AI. So this is interesting always. The biggest barrier to the use of AI and healthcare has to do with infrastructure. So health systems need to enable algorithm algorithms to access patient data over the last several years. Large well funded systems have invested in moving their data into the cloud, creating vast data lakes ready to be consumed by AI. But that's not easy for smaller players. And another problem is that every health system is unique in its technology and the way it treats patient that means an algorithm may not work as well everywhere. So we talked about this independent study and a widely used sepsis detection algorithm from EHR, a giant epic, we all know company epic, and it showed poor results in real world settings, suggesting where and how hospitals used AI mattered. Just throwing AI at it does not really solve problems. It's really a fine tuned precision sort of surgical application for AI. And it also mentions how that radiology is dominating in terms of FDA approved AI enabled devices. Next article here is related to the Ethereum merge. So, as we know, Ethereum is moving from proof of work to proof of stake, which is reducing its carbon footprint significantly. This is apparently happening in September. That's the plan mid September at some point. And, you know, this is something that's been in the planning process in development for essentially almost, you know, years now. So it's a huge milestone for the Ethereum community. And we will see how it ends up at this. There's so much speculation around this. But there have been many efforts to ensure that it's been tested thoroughly. So, you know, proof of stake is already working on their test nets. So anyone curious about the merge or working on the merge or have any thoughts or comments to share about the merge? Okay. Well, I'm sure it's significant. I know that hyper ledger platforms and hyper ledger tools and applications. Some of them that are connected to the Ethereum protocol will also have some changes as well so there's work to be done and managing that. And just to add to that, this is more honest. They just recently did the merge on the test net, I guess, and they are figuring how we're just working. But overall the merge does not impact any of the application development or the developer side. It's only impacting the validators, ultimately. And essentially they're moving to proof of stake. And really it's impacting the validators but they have put some controls and rules in terms of validators cannot disconnect their machines validators don't get access to their funds immediately at least for now. And then that they have to run two nodes, right? Essentially the consensus node as well as the execution node. So I think they are figuring out all these things and there is a gradual transition towards using Ethereum 2.0, which will finally become Ethereum. They'll drop the 2.0. Right. Yeah. And the, as you mentioned, the test net blockchain, Gorely was made, you know, was activated on August 10th or that transition happened. Recently. Very recently, sure. Definitely. And it seems it went okay. The test weren't flawless. Some validators went offline in each test for different reasons. Ethereum can continue to function. However, so long as most validators continue to remain online and no group of validators falls out of consensus. So there is a little bit of risk here. Yeah, there was some random news on after the merge, I think the value of Ethereum dropped below 1900, but it's still 7% up from whatever it was, you know, so I was trying to figure out out of curiosity, why did it drop? And not that it is a significant drop, but below 1900, but it's picked up back. Yeah, it's true. Yeah, a lot of good information here. From the quidium side, I probably should know this, but I don't. The, what the impact on latency and cost and other things this anyone have a sense of what that is. The transaction fees materially drop latency improve substantially. I think the the blog actually on the Ethereum website has got the, the myths about the Ethereum merge. So there's no change in the latency or whatever it is. So the questions you're asking is documented there changing the transaction fees. It's, they have a fixed price plus a tip, and that tip gives priority to transactions, and the way the validators get compensated. There's a slight change, they still get their base, but they also get access to the tip and stuff like that. So, good question actually, you know, so I was also very curious. Yeah, I put a link to the misconceptions page in the chat as well for anyone who's interested. Yeah. Okay, thanks for the questions and feedback here. A couple educational nuggets from the last couple weeks, one is the decide an idea market saw a sub stack related to how decide can generate these idea markets without institutions. So basically, what they're trying to do is create credibility without institutions. And the way they do that is these on chain ratings, and they generate a list of people who are confident in the results of a study. So it's basically like a seems like a voting sort of mechanism, or rating really not voting. Yeah, here it says in the same in the same way sub stack is helping you shift trust in journalism away from institutions and towards individuals idea market enables credibility credibility on all topics to follow the same pattern. It won't be long until the opinion of 100 people you trust outweighs the opinion of one institution you don't. I thought that was interesting. It's also still challenging to accomplish this because it could be 100 people that, you know, we have to be able to trust that these 100 people are knowledgeable about the subject. Because the institution we can currently we can rely on them to a certain to a certain degree at least. Yeah, so I just want to put this here it's got some information on how new income streams can be developed for D size well through a rating system. And yeah, another huge piece of news that came out was related to tornado cash and us sanctions. So if you haven't heard tornado cash, which is a protocol built using a theorem smart contracts that enables users to essentially wash their Ethereum or make it so that it's hard to identify where the original Ethereum came from obfuscates the origin of those ETH through like a mixing laundering sort of protocol. And obviously, the government is not going to let this continue without trying to stop it. So what they've done is they shut down the website as well as arrest. And the Netherlands, one of the developers for tornado cash was arrested. And so now there is a huge debate between privacy, freedom of speech and protecting citizens as well on the other side. So, yeah, this is going to be something that people will be talking about for a while. I think it also has a lot to do with the blockchain community overall. In terms of censorship resistance and privacy. So, and what I've read and please correct me if I'm wrong or if anyone has any other opinions but whatever it is that tornado cash does have some legal standing to defend itself. Based on legal precedence versus the US Treasury. So we'll see what happens. The department, the US department US Treasury Department seems to be blatantly going against the prevailing law that open source software is equivalent to speech, which is protected by the First Amendment of US Constitution. So, we'll see what happens. I think the tornado cash Dow has been raising money or they've been voting on whether or not to to appeal or to sue the US Treasury. So we'll see how that all turns out. People's githubs have been suspended as well due to this. So, interesting question here is could tornado cash is hired legal team be arrested. But rest seems to be an intimidation a tactic they shot across the boat to warn other developers who write privacy oriented apps and dApps, considering that the financial action task force coordinates both anti money laundering and legislative efforts from South Korea to Panama such experience was to be expected. Anyway, this also can apply to our health data in the future, because you know essentially, if we believe our health data is also should be private. And we want to keep it that way. You know, our government's going to be okay with that. Right now our data is private until the government wants that information. For security purposes, national security purposes so yeah. And if, yeah, okay. And finally just the health on chain podcast, I published the 100th episode of the podcast where interviewed crowdfunded cures, which is a Dow, and they're helping other dows like Vita Dow and molecule develop their their models as well so check that out if you are are interested. That's all I had for today's agenda but if there's anything else that members here would like to share discuss. Did I miss any important news of the week. Are there things that you are working on that you think people should know about. Congratulations on your 100th episode. That's a huge milestone. Thank you. Thanks Wendy. Appreciate that. Yeah, it's been three or four years now been working on this podcast so I'm pretty excited to be able to get to 100. Thank you. I'm going to do it with you all listening people give me suggestions and feedback all the time. And if you this person or this company so if you feel like there's a project going on that needs some attention. I need to listen to that. All right. Well, thank you all for joining today. It's were a bit early to end but I think that's okay. Any final thoughts or questions. All right. Great. I'll stop recording here we'll join. Please join us in another two weeks for another meeting. And in the meantime, you know where to reach me. Thank you. Have a good day. Thank you.
