Okay you are now live and welcome everybody to Hyperledger Meetup. I'd like to introduce the speakers today who will be speaking about fabric private chain code so for that take it away please. All right thank you David for for hosting us actually all right uh-huh so you I think you see also the that screen that we try to make it a little bit smaller so can someone say that you still see my screen yes awesome okay all right let's talk about fabric private chain code so I'm super happy that we have the chance today to share this exciting project with you um so this is the project is called fabric private chain code we are a hyperledger project I mean for providing a new feature for fabric with the subtitle confidentiality confidential chain code execution for hyperledger fabric using Intel SGX so today we are three speakers so it's me Marcus I'm with IBM Research in Zurich then we have Maria with Home Lending Pell and then we have also Bruno from Intel Labs and I suggest that we should start with the motivating so why why does this project exist okay and I use that some words maybe here maybe even smaller great okay so I hope that the audience is familiar with blockchain technology and that even we have people here on the call who are familiar with hyperledger fabric I think that's also the chance to check if this can be an interactive session so I would suggest if someone is familiar with hyperledger fabric please hit a plus in the chat channel and see if we have some people here actively listening awesome I see pluses that's amazing all right okay so even more pluses awesome so I guess I mean since you know hyperledger fabric I don't know maybe you have already thought about privacy sensitive use cases on hyperledger fabric so what do I mean with sensitive use cases so there I mean we know that blockchain technology is is nice for very different applications in particular for the verifiability aspect which is provided by blockchain however there are use cases which come with certain security requirements in particular privacy requirements let's take a few examples here what I mean was that think about a sealed auction there we understand that in the sealed auction or a secret auction the the bit secrecy should be maintained during the auction and in the end an auctioneer reveals the winner of an auction very similar e-voting right so we understand that in the e-voting scheme or in the general voting scheme we submit our ballot and this ballot should maintain the secrecy right and nobody should ever learn what was my particular vote but also health care use cases where for instance genomic data analytics is happening there we also have a quite good understanding that those genomic data is very sensitive data because it allows to identify humans right it helps to identify people and in a supply chain use case where multiple organization they would like to exchange assets for some value for some money right but certain contracts should not be revealed in particular people are not really interested in let's say revealing the price they paid for a certain asset to competitor for instance right so luckily luckily fabric already comes with a bunch of privacy mechanisms built in so for instance we can have channels some of you may already know the concept of a channel so we can actually split the blockchain and multiple blockchains and only participate let people participate in the channel who need to participate for instance in the supply chain we could say okay only the two organizations which are interact with a contract they are on that particular channel that excludes automatically competitors from that channel and from the details of that contract a second mechanism is private data collections for instance I think there was talk about that here on this meetup I think in November so there we learned a little bit more what that means however the recap the basic idea is that we use the letter the blockchain only to store hashes of the data we are exchanging or using in our smart contract and the real data goes between the organizations through the data through the data collections in some way of offline communication direct communication and then the third thing is transient fields which allows us to add data to transaction without adding it to the transaction that means we can submit data to the smart contract to the chain code without this data ending up in the transaction itself which is then later committed to the blockchain or stored on the blockchain however all these mechanisms they have a problem and this is the data visibility at the endorsing peers and the respective organizations so what do I mean with that so think about that in hyperlative fabric there are endorsing peers executing or running a smart contract computing a result then sending it back to the clients and then a transaction is generated and submitted to the network however these endorsing peers they execute a smart contract and in order to execute they need all the data if we now take our voting as an example back here even if the the ballots are in some way encrypted they need to be decrypted at some point by the smart contract processing them and then there's some computation who actually won the election that means that the endorsing peer from a securities perspective has access to the clear data if we now imagine that the government would run such an endorsing peer then we could say well maybe this is not a good idea right depending on if you trust your government or not but I mean this is just an example okay and so in order to overcome now this problem of data visibility we introduce what we call fabric private chain code which is a framework to build deploy and run private chain codes on hyperlative fabric so fabric private chain code accommodates blockchain use cases with strong privacy requirements for instance those examples I just gave and it does it by executing the chain code or the smart contract by using hardware based trusted execution technology like Intel SGX and by using that trusted execution technology we basically get three security properties for our application which uses fabric private chain code but the first one is confidential compute which means that all the transaction and the letter contains only encrypted data the second is verifiable operations where transactions can be or are verified through a mechanism called attestation which is something provided by the trusted execution environment I will come to that also in a second and the third property is data misuse prevention because with this technology it allows us to bind the data we are using in our transaction to the intended chain code okay let me quickly talk about Intel SGX so the idea of Intel SGX is that you take your little piece of code you would like to protect in a certain way and put it in a container or an Intel SGX speak often called Enclave which helps you to reduce the trusted compute base at TBC that means that if my application runs in such an Enclave then we only need to trust of course the trusted execution technology but only the the actual application running inside such an Enclave when you think about the traditional way how the trust model in fabric or any other application works is that we have our application and fabric this means our peer or fabric peer which executes a chain code and this relies on the operating system it relies on the trust of the operating system and the operating system relies on the trust on the hypervisor on the and the hypervisor on the hardware and so on so if we now I mean do a computation in that model we just need to trust the entire box the entire machine that the execution of the chain code is correct and that nobody steals my data with introducing Intel SGX this picture changes a little bit what you can see here on the right side and it changes in a way that we take now our chain code or a smart contract put it in an so-called Enclave which is protected by the hardware itself this changes our security model in a way that we do not need to trust the peer anymore but we only rely on the hardware or the trust in the hardware and the application itself and by using this technology now we get essentially let's say three basic security properties the first one is confidentiality that means that only the Enclave sees the data which it processes so that means that the peer for instance cannot look inside the memory of the Enclave for instance and extract certain secrets the second is integrity where the hardware ensures that the intended application in our case the chain code is executed as intended and the third property is verifiability which links to the property I've mentioned before the hardware-based attestation which allows a third party to ask the application running inside the Enclave hey application are you running inside a trusted execution technology and what are you exactly and that process of attestation will then produce a proof that it executes a certain application or chain code inside a proper hardware-based trusted execution environment like an Enclave so with this understanding now or this brief understanding what Intel SGX is I think we can look in how we're using this actually I mean I think you get the rough idea now we're running our chain code our smart contract inside SGX for more details on SGX I would definitely recommend to look on the documentation on the Intel website if you want to learn more about that Marcus there is a related question in the chat Indira Jit is asking Intel stops its SGX with its processors right would it affect this function so huh okay so I can answer that or do you want to answer this I guess I can answer the first part maybe you can follow up so Indira Jit I guess you're referring to the unavailability of SGX on some client processors and well that's the case but SGX is still available on on server processors particularly on on Ice Lake for example where you can have larger Enclave size so you get more performance so in SGX is available Marcus yes I mean I can try to answer the second part of the question would this affect this function and yes so if the processor does not is SGX capable then we cannot use it in that case right that's definitely a risk however I think it's it's very interesting because there are I mean other uh TEE trusted execution environment vendors which provide similar technology right now we fabric private chain code focuses on Intel SGX because it fits clearly in our security model because we are interested in protecting a chain code application other TEE technologies like AMD SEV they are or they aim to protect entire virtual machines which is which are much bigger than just the chain code this this is just maybe to give you an intuition why we are using Intel SGX here but our in in general I would say our architecture which we have not talked about yet but it's also applicable to other TEE technologies other than Intel SGX but with this let's have a look at the architecture so this gives you again just a rough a rough overview or brief overview on what fabric private chain code looks like so what you can see here on this graphic is I mean the basic components of a standard fabric network I mean we have a bunch of peers we have an ordering service and we have a client or client applications which all together interact and allows us to to run applications on top of the blockchain from the previous slide we already got the idea okay that now the chain code runs inside an enclave which isolated from the execution from the the endorsing peer and through that hardware mechanism all the memory content of that of that chain code or of that application is actually protected from the peer so and this is the first let's call it the big change the second big changes that we are injecting a little bit of additional logic in the deployment phase of a chain code where initially a consortium which runs or wants to use a chain code together they agree on something called a chain code definition and in the chain code definition we now include what we call mr enclave which is a unique identifier of the application or the chain code running inside the enclave and this vehicle we are using to enforce that only the expected chain code protected by sgx is is used during the lifetime of the smart contact or the chain code Marcus we have two questions one is Luciano who's asking what would be the advantage of isolating chain code from the peer so I I hoped I was already answering that question and directly with my motivation slide so the idea is that I mean in a block or the general thing in a blockchain system is that a smart contract is executed by multiple participants so if so I I'm working for IBM if IBM runs a peer I can trust that organization to do a proper execution however we know that in February we can specify an endorsement policy which says okay this chain code needs to be executed at multiple organizations but what if I do not trust one of those other organizations entirely so I would reveal my sensitive data to that organization let me bring back that example of an often often of a voting if the government runs a voting system it runs a peer right I would send my encrypted ballot to that peer of the government and the government needs to decrypt the peer in some way okay let's not talk about I don't know multi-party computation homomorphic encryption things like that that's a target to that but so the the key point is that you maybe maybe there are also situations where you trust the organization but you maybe do not trust the the host where this peers actually hosted I mean maybe that peers I don't know hosted and on a malicious cloud provider so there are definitely some cases where you are not fully trusting a peer I hope that answers that that question a little bit and then sorry yes only one more question to compliment the the other one so this enclave from Intel is something centralized where the chain code leaves well it's it's not centralized in that sense so every peer would run an enclave and every enclave I mean an enclave belongs to the peer in the end of the of the day but I mean as I explained we have a different trust relationship here but I mean the the thing is that we should still have the opportunity to send our our transaction to multiple peers multiple enclaves to do that I don't know if you're already familiar with fabric private chain code and then saw something different so there is so we have some implementation limitations at the moment that our current prototype only supports a single enclave per chain code but I mean this is an implementation issue not a conceptual issue I see any other related question to that I think it's very nice when people are asking the questions instead of typing them Adam and Marcus Adam made a question says how do you make sure that the code is run in SGX hardware and not in some kind of emulation layer yes so for that there exists this mechanism called attestation what I what I was also mentioning before which which let the hardware produce a cryptographic proof which you can verify later and that actually plays together with the with the identifier of the actual chain code as defined in the chain code definition using that hash of the application the mr enclave and with this cryptographic proof you received from the chain code you can verify that and ensure that this was not generated by an emulator layer for instance there are of course SGX simulation modes which I mean which cannot provide such a proof but then there exists a fake proof which you can clearly see that yeah this is a fake proof this this does not run in a protected environment it's not secure but maybe it's still usable useful for developing purpose all right um any other questions no not for now at least on the chat all right so let me now finish this slide and then I will give to Bruno so um two more things so as I already said so now we have protected or isolated the chain code from the peer and in order now to communicate we also need to establish let's say I call it a secure channel between the the actual application and the chain code through the peer that means that fabric private chain code gives you a mechanism um in form of the fpc client SDK which you can use in your application which is responsible for exactly doing that so it's responsible for encrypting and authenticating all the transaction inputs in a way that only the chain code inside the enclave can decrypt and then use that data and the same actually happens for all the data which is stored on the letter or in particular on the word state you know that a chain code can access the word state by performing get state and put state operations and there the fpc chain code makes sure that this data which is stored outside the enclave on the word state is encrypted in a way that only the chain code uh inside the enclave can later decrypt and access the data and clear again all right and I hope now we have an an understanding so what we can do with fabric private chain code and with this I would like to give to Bruno um to talk about a particular use case in the in the healthcare area uh and let's let's see how this is useful to use all right so Bruno do you want to take over the share screen yes hopefully you can see my screen so we still see powerpoint not the full screen version right there we go okay so let me discuss this use case on healthcare and particularly on um clinical trials that we developed with um uh with our partners at soft thread a startup that deals with um works in healthcare uh so be brief background on clinical trials uh well probably you are a little familiar with this um so these are um this is clinical research that is performed to assess the safety and efficacy of drugs and treatments for for people and this use case was interesting for us because there because there are several individuals and parties that participate in these um clinical trials and in the end there are lots of regulations and the data to be protected and of course you need some means to um automate all the procedures and making sure that um security is preserved now let me uh quickly go through some peculiar aspects of these um clinical trials so as I said there are multiple parties and to make a simplified picture you can see that there are at least four you have an institutional review board that takes into consideration and approves proposals for clinical trials for investigators you have subjects that provide the data that has to be um eventually analyzed uh the investigators conduct the trial and maybe some experimenters will um take care of actually analyzing the data in order to um get to a result now there could also be multiple institutions uh but just to keep things simple right now let's just deal with a with a single one which is um already complicated enough enough now since you have to deal with the um patient data uh then uh there are some regulatory compliance to um to deal with uh like for example you always have to make sure that you maintain the the safety of the participants or in the US for example you have these hyper rules or regulations which mandate that the data is treated according to some standards like it that it always has to be protected there must be access control you have to preserve the integrity and always encrypted it must be always encrypted when you um when you store it somewhere so there are several um objectives that must be met in order to comply with this clinical trial with with the with the regulations and one thing that it's not showing the figure uh is the auditing capabilities so uh there is another party usually um public department that takes care of um auditing these clinical trials to check post facto uh whether something has happened and then uh take some countermeasures maybe something that was happened like in data treatments in that case some fines will be issued so what are the the challenges in these clinical trials um well the big question here is to out how to automate and secure them now let me point out that we're not talking about um automating and securing um the physical collection of data from patients or blood samples or anything like that here we're talking about digital data in how to automate and secure um its analysis now of course if you are able to automate these procedures well um you reduce time you save some and you save some cost now for data management and and regulatory compliance things get more um more complicated simply because you again you have multiple parties to deal with and you have to understand where do you place trust whether you place that in the uh in on the individual or on the institution and how can you um better reduce uh the um trust boundaries in order to um improve security in these cases just one second okay uh so the usual um so the first question that comes up is how do we solve this problem and usually the first answer is well let's use a blockchain um and this is what our partners started to um started to do uh blockchain in this case uh means that if before um forms and sensitive data were collected through um uh paper forms um for example well now they can be easily collected and distributed by using a blockchain such as um hyperledger fabric now although this works and brings some benefits um because you are really automating these procedures well things have not really changed from uh privacy or confidentiality perspective simply because before you had uh individuals uh trading uh paper forms and now you have still individual trading uh pdf forms um for example so you still trust the individuals and uh the approach that is being followed from a security perspective is a trust and verify it means that okay i'll give you my data and i trust you not to do um anything unintended and i trust that there will be some auditors uh in the background that will control what you do that will check what you do uh and with the digital data is um basically the same thing um but um uh and still you're relying on the auditors and perhaps things are even a bit worse because because by using a blockchain you're actually distributing this data to uh a multitude of parties simply because the blockchain is um uh shared uh by default although it can be permission in the case of um hyperledger fabric so how do we solve this problem in um with fpc well the idea in fpc is that uh you can reduce the privileges that you delegate to um to the parties now here i have a complicated pictures of um what happens logically uh but hopefully i can help you make sense of that so initially we had the direct interaction interactions between these parties like the subject and institutions the institution to um provide consent for data processing and also the itself or you have the institution um delegating the conduct of the trial to the investigator so the idea in fpc is to uh logically centralize um all the steps uh and the verification of the steps uh instead of an enclave but again i said logically centralized because we are building um fpc on hyperledger fabric so it's in practice it is decentralized so this enclave would essentially contain um all the implementations to um gather sensitive data from um from the subject as well as any approvals from related parties like the arp for the approval of the um of the clinical trial or the investigator to approve experiments that the experimenters are intended to run and only that and only when all the regulations are met uh and the proper checks also are um uh have been um analyzed and controlled by the enclave only in that case the enclave will take care of transferring the sensitive sensitive data from the experiment approval chain code to another experiment always inside an enclave in order to protect confidentiality so by doing this you uh reduce reliance on individual parties and actually increase trust on um automated and verifiable third party agent which is implemented inside inside the enclave which is supposed to implement all the regulations regulations and checks that will allow you to um eventually increase trust and security on data management okay so this is a picture of the demo that we actually built with um with our partners uh again I understand it's a bit intricate and big but it is a big and complicated use case indeed um all these components and and whatever we built you can find that on on our repository on on github so I will just walk you through these um these components to give you a better idea of what's going on and then I will show you a video for how it works in practice so again you can see the different parties that I showed you before so the ARB that approves the the clinical trial and the the approval of the clinical trial and the consent um part from the user these are uh have been implemented by our partners and they're based on plain hyper ledger fabric um the big challenges came when we had to deal with with secrets and manage confidential information and in that case we didn't want of course to um um to release those to all the peers on the on the fabric network and for that reason we uh wanted to rely on on fbc and so on uh hardware-based confidential executions or chain codes for for fabric so what happened here is that the subject will register some data with the experiment approval chain code and it's a registration with um with a promise in this case and the promise is that is something like promise me that you will not release the data to parties that have not been previously approved or experiments that have not previously approved so again that enclave is supposed to implement all the policies and regulations that have that have to be enforced um the investigator will take care of approving any experiment that the experimenters want to run so in this case the subject does not have any a priori knowledge um of what will be the data analytics um in um in the experiments um and uh that's reasonable because there may be different ones um that can come up and once all the approvals and the registration is um is in process then the experimental approval chain code inside the enclave can make can determine whether the um experimental data so that subject data can be provisioned to the external enclave or not um and if so it will be provided to another enclave at the experimenter side and um the data analysis will happen and it will just release the final result to the experimenter so let's go um through the video here so we implemented the uh different parties in this case particularly the data provider which is the subject an experimenter which will run the analysis and the principal investigator who has to approve the software before being used here we have some patient forms I will show you the uh what they contain that will be sensitive data um we have a diagnosed function which is the data analysis that the experimenter wants uh to run and I consult on the side that just to keep track of what's going to happen so this is the patient form is a standard pdf with sensitive information like the name of the patient, birth date, and some questions that the user has to answer like the temperature whether um now is occurred and so on and the point of this pdf form is that eventually the experimenter has to understand whether uh whether this subject has a high probability of having this nephritis of renal pelvis origin so this data will have to be analyzed okay so let's play the part of the data provider or the subject so the subject uploads the data to um now our blockchain um select some options during the upload phase what happens is that the data is encrypted first uh and the secret encryption key is registered on the um fbc chain code while the encrypted data is instead uploaded to an external database this is really uh an optimization simple because the blockchain is a an expensive database and so you don't really want to use that to upload arbitrarily large data okay once this is performed let's play the part of the experimenter the experimenter decides that he wants to run um an ml machine learning inference model over the sensitive data and to do so he decides to use this diagnose python function uh which will use the patient patient data to make the inference now the important part here is these data items visit items are the variables in the code that will contain the sensitive patient data but of course the patient data still has not been disclosed um to um to the experimenter or to this function for the analysis okay so the experimenter submits a description of this experiment together with the code to the investigators for for approval the experiment the investigators are notified that there is an experiment pending approval here three of them are alerted of the new experiment but according to the policy that we implemented a single approval is sufficient um to um for the experiment to be approved so the investigator has access to all the information about the experiment the description and particularly the code uh that is able to um to review before making a determination in this case everything is fine so the investigator goes ahead approves the experiment now the fpc chain could consider considers that as completely approved and the experimenter is ready to launch an instance of this experiment so what are you seeing here um is um an instance of the other enclave the second enclave uh the one that contains the um experimentation service uh and this enclave is the one that contains the experiment code and it's the only one that is able to um to interact and authenticate itself with the fpc chain code uh for the sake of making sure that the experiment was approved and so that this enclave is eligible to receive the sensitive patient data so there is a public key for um authentication and also for establishing a secure channel the experimenter runs the experiment receives the patient data the enclave grabs that from the external database and eventually it um is able to get the final result which is um 19 percent and this is the probability that that particular subject has um these of having these um the Fridays of Reno public's origin and again this is the only information that is uh eventually released to the experimenter um this is because it's how we implemented that uh and so the experimenter did not have access to um any patient data so we were able to preserve the confidentiality from uh from when the data was initially provided to um the experiment approval chain code to the fpc chain code up to when it was um eventually analyzed without ever releasing that okay so this concludes the experiment um the use case we have um two questions one is from Neo who says in this use case does the subject need to hold a private key for transaction signature if yes may I know where is the pk held and does the intel sgx have access to subject private key may I know if um if it performs inside sgx uh okay so uh yes to both um yes to both and uh the the reason is simple the subject has to um of course authenticate itself um in these um in these procedures uh in the end it's a client contacting um an fpc um an fpc chain code and since this is based on fabric well we have a fabric client and a fabric chain code um in the background so for the sake of authentication yes uh and those keys are held um locally at the subject side uh and they are yes they're used to um essentially um trigger transactions on on fpc uh I would also add that these public keys should also be registered with the chain codes um simply because the the fpc chain code has to um authenticate or verify that the subject uh indeed is a subject enrolled with the institution for that clinical trial now the second part of the question is uh does the enclave um use some public and private key pairs uh and the answer is um yes uh and of course yes because it has to perform some digital signature of what it's computing and also it has to authenticate itself with the with other parties because parties such as the subject has to make sure that it is um talking to a legitimate enclave so these enclaves these keys are generated by the enclave at um startup time um and they are attested through the hardware-based attestation mechanism that marcus um quickly introduced introduced before so in the end the chain of trust that you will eventually verify in order to establish trust in those keys is that you will verify the hardware the hardware will tell you that it is running a certain piece of software which is this experiment approval chain code and this piece of software will include those public keys inside inside this attestation so essentially you will refine the whole chain you establish trust in those keys and eventually you can use even the private key inside the enclave to um sign any statement other questions no the other question marcus um answered it on the chat okay so again this demo is available on um on our repository um talk to us if you need additional information about this or about how to run fpc or um order them itself and uh i will stop sharing um and maria can take over so while we're switching here the the gears uh i mean so our repository is on github it's called fabric private chain code um we also show the link later here in our slides um but i can just answer this question while we're changing things fabric private chain code just google it you will find the first first set so just to do a bit of a recap okay um this is the architecture and what are the components that we have to develop so there are two components the fpc chain code and the application that is accessing and calling that chain code right so how do you develop both of those the first one is the chain code how do i develop the chain code so the chain code you have to develop it on c plus plus this is because we are since we are running in an efficient environment um that is using sgx this is a requirement of sgx to develop in c plus plus now we have provided a shim to be able to handle a lot of the logic that is required to do the encryption decryption processing and all of that we are actually develop that shim is on top of the current fabric chain code um functionality so this is not completely different from what you can get with the uh fabric chain code the only difference is that here when you for example here you call the get state or the put state you will not have to encrypt um the uh the parameters before because uh that will be done when the when the invocation is made okay so you only have to import our shim as with any chain code you have to develop the the the invoke and this is where you would program your the chain code logic now if we move on to the client side we need um fabric provides a fabric client sdk in go so as with the chain code we develop on top of that um sdk and since the fabric um client sdk is in go we the fpc client sdk can also be in go um these this sdk manages not only the interaction that we have like here that we have a submit transaction and an evaluate transaction but also the um life cycle so all of the functionality to be able to implement deploy um a chain code into an environment okay here we can see that we get a contract we submit the contract here we can see the values again that is because the um the shim is is the one that is doing all the transformation and here we have an evaluate transaction okay and how can i say so that's the theory of how everything is done and i want to get my hands dirty how can i do that well this is our the link to our github repository where um you're going to be able to find all the things that you need and if you if you don't you can ask us or you can post it and we'll try to help you out right the important thing is also that you're going to say and um one of the first questions was intel doesn't is not um using is not um continuing with sgx and bruno said no it's not doing it with um the client uh processors so if i want to develop i don't have a big ice lake server where i can have the sg how can i do that we provide dockerize development environments that can simulate that sgx so you've got the the hardware well better for you we still do provide a dockerize development environment so you can run everything in there and make it more simple for you and if you don't doesn't matter you're going to be able to develop the same way because you're going to be using sgx simulation now in our repository we have different samples okay the the simple the simplest sample is the hello world tutorial that will help you not only develop the chain code but also develop the fabric client to be able to access and execute that chain code okay and one of the questions that was asked on youtube live was i want to add it to my network how can i do that one of our samples is hey remember the the fabric sample of the how to create a test network well we show you how to add fabric private chain code to that sample okay so it that way you okay you learn how to do with the test network you create your network we'll follow the same rules and just add the bit that we have added so that you can do that and it's not only with the test network but also with kubernetes and bruno just presented the irb demo and something that i would like to add to that is he mentioned that it is in our repository um but also that there we are using a fabric smart the fabric smart client what does this mean he showed all of the different participants so that network is not a simple network and if i'm i'm a developer and i have to set up all of those peers to run on my um laptop it's going to take me a long time okay because it's not already set up i have to do it so we pay back on top of fabric smart client that provides programmatic logic to be able to define that network and get it created and that simplifies the development process it also has uh the ability we've integrated it so from fabric smart client you can also call our utilities our chain codes and that way makes it much simpler to be able to develop a solution to whatever your problem is and i've tried to we've got two minutes left for questions i wanted to take you guys to the github repository but i think it's going to be much more useful if we open this up for any questions if if you're um on the zoom call you can open um your unmute your microphone and and and ask a question or if there's already a question in the chat we can answer it so there is a question on the chat um hubert is asking is it possible to interact with other blockchain say i want to build a smart contract on say a cerium to give some token to those uh giving uh away their data on fabric blockchain how difficult would it be to implement uh i think this is a good question i i also think this is a little bit beyond fabric private chain code um well i mean my answer is um i don't know actually um but yeah i mean you can definitely build a fabric private chain code um which can uh let's say process details of of inputs data you're also presenting to in the serums smart contract i guess but so we do not provide any functionality or any layer which makes let's say our technology is that compatible with for instance the serum i hope this answers the question at least a bit any other questions just just feel free to unmute yourself and just jump in here okay i guess it's 10 and pst at least uh i guess we can wrap up just one last question um um marcus i don't know if you want to answer it um alec dander was asking about the chain code life cycles yes absolutely so i mean with fabric private chain code we are let's say exactly following the same uh chain code lifecycle i mean you have to you have to package it you have to install it i mean deploying it you have to approve it i mean all the organizations they have to submit an approved by my org transaction and then at some point you have to uh i think it's called a commit commit uh chain code definition transaction the only thing what changes here is that as part of the chain code definition we add the unique identifier of our chain code inside the chain code definition and with the unique identifier i'm referring to that hash of the let's say the hash of the compile chain code the expected chain code so we add this to the chain code definition so this is this is one piece how it changes then we have we have a component which we call the enclave registry which is implemented as a chain code we have not talked about that yet today because this is nothing we are exposing to the users of fpc so our client sdk and um our entire framework tries to hide that component however it is crucial for security because when it is it is used when a chain code actually is started there is this process of um or there is one additional call we add to the life cycle which is called register enclave which uh you an admin of an organization using our sdk performs at a certain peer which tells the peer hey please start an instance of that fpc chain code that fpc instant then does what Bruno explained a little bit it produces uh some uh crypto keys it produces a remote attestation which proves that it runs a certain chain code and it's protected by the hardware then this attestation is sent to our enclave registry component which looks at the proof and checks that this proof contains exactly the same hash which was defined previously in the chain code definition and only if that matches then we actually allow the the enclave to be registered and to go live in the system that's one thing we have not talked about today one other minor thing is i mean this goes really into technical deploying details for fpc chain code is that we are relying on the external service functionality of a peer in order to to spawn a chain code as you know from from go chain code or javascript chain code there you normally when you install it on the peer you tell the peer hey here's the code please um compile it package it as a docker container and then there is a docker container running at the peer our entire build framework gives you the the tools in order to create that docker container for you then this will be shipped to the peer and by using the external service or the chain code as a service mechanism the the peer is able to communicate with this docker container where now our fpc chain code is running those are let's say in in in just two minutes how the lifecycle changes but we really try to keep as as close as possible to the normal fabric lifecycle um Maria told you about the fabric samples test network if you go to that tutorial on our repository you will you will see those individual steps very well explained um in the read me you can follow them and I think then it should uh yeah everything should be clear how this is different from a normal chain code lifecycle all right I think we're over time are there are other questions there's one last question is it possible to use fpc to privately store input data on the ledger to be processed later similar to voting the votes will probably be calculated at some moment in the future absolutely so this is actually the use case for fabric private chain code the idea is that we send our data in a way that uh it is only um visible to the actual fpc chain code the fpc chain code can then store that data on the ledger in an encrypted form and at some point when you want to process this data you can trigger the chain code until and now it's the time please do something with the data the chain code gets the data decrypts it process it and without revealing it to the endorsing peer that's actually the use case of fpc right and last just to finish I want to invite anyone who likely idea and wants to help out we meet on Tuesdays you can check the the time on the calendar on the hyper ledger calendar of when our meetings are and we are open to anyone who are two new contributors so um all right David here should thank you thank you David thank you for everyone for joining and um yeah hopefully we will uh talk to you soon all right thank you guys have a good day everyone have a good day thank you bye bye bye


Welcome folks, this is Tom O'Brien of TFNN. We have five days a week, we have seven hours a day, we go 24 hours a day in the internet at tfnn.com. Always remember folks, whatever you think about, you bring about whatever. You focus on grows, hope everyone's having a great day, safe day, let's make it a great night folks. Replace fear with love, this is a great card man. The human mind is like a fertile ground where seeds are continually being planted. When you're impeccable with your word, your mind is no longer a fertile ground for the words that come from fear. Your mind is only fertile for the words that come from love. This whole world is in fear right now folks, it's a joke. Get rid of the fear, love is a lot more fun man. Guys, let's take a look at it out here, we have the Dow Industrial's down 486, Nasdaq down 335, S&Ps off 78, Gold contract down 340 at 1821 an ounce.  Right sweet crude up 225 trading at 111 dollars, 81 cents a barrel, notes and bonds. The 10-year note, down one, 116, 25, the 30s flat at 135, 10 and King dollars, King dollars on the move. King dollars up 566 ticks, trading at a price point of 104, 506. You get the Euro at 105, the yen is at 136 to 120, 136.21 and the British pound is at 121 to one US dollar. iPhone number is 877, 9276648, give us a call folks. I know what's going on in your world and the world of the S&Ps, let's take a look at them. This is a sad commentary folks because the bottom line is that this market is so weak it's incredible. So picture what we have here, okay? So what we have here is that you know, you had the big sign of strength on Friday, that was, you know, rebalancing, bottom line. You had a one day wonder, you did 98 million shares, yesterday you got above it, you failed on price, failed on volume, 66 million. The other thing that's amazing is that we're actually gonna do light volume today, you know? But what happens is this, we try to get to a higher high. So the bottom line, this is a higher high with light volume and the market lets loose, bottom line might, you know, July 4th and not July 4th looks to me like this thing's gonna go right after the lows once again. So that's on the, that's on the spies, on the queues what you have, it's not, I don't, I can't see this making the gap, that's the bottom line. And the X100, the three queues, that is the one that's calling out in spades because the three queues couldn't get to a higher high today where the queues where the S&P did. The high of yesterday on the three queues was $296.57. We got to 295.65 today, bottom line couldn't make it. And the queues are gonna have an expansion of volume. Bottom line is 54 million yesterday, you're at 49 today, we'll probably do about 79 million. And then if we get, let's just go right to the dollar because you can see that what has happened is this. You know, the dollar, so picture this folks. The dollar, let me go and bring this back because the dollar has been on a run higher, okay? For a huge amount of time, you know, we take a look at the shot, what you're gonna see, okay, going all the way back to, let's see. Yeah, January of 2021, right? The bottom line, dollar's going up, market's going up. No big deal, right? Now folks, guess what? It's a big deal. This is the, this correlation was direct. I mean, when you see this dollar, each time the dollar's going higher, bottom line, markets going lower. So, when you take a look at this dollar and we put this up, now this is where this gets dicey because it looks to me that this dollar is actually gonna go, well, it's going for, it's high right now. Let me just see, hold it. Yeah, it wants anything over the 103. Yeah, anything over the 103, man. It says it's going to 121. This thing looks like it's really gonna go to 121. And it's making more sense to me now too. And what I mean by that is this. The fastness of the move as the dollar was going higher, market going lower, right? And what we have is that we have ABC structures down. We have multiple ABC structures down on the S&P, NASDAQ, small caps. So in order to fulfill that, that's telling me the dollar's gonna go higher. Well, if the dollar goes much higher, the dollar's gonna go to 121. Dollar goes to 121, bottom line, you are gonna see some real destruction in this market. Bottom line, get ready if you wanna go to Europe to buy some euros though, because the euro will be at 87. That's how this shakes out. We pulled this off. And don't forget, our man Mr. Teddy Kegstad just started the Tiger Forex Report. Yeah, this is a great time to check it out folks. Cause I'm telling you, the dollar is moving the market. You know, up and down. That's the real bottom line. As you go over to TFNN, you're gonna see the Tiger Forex Report right in the front page. Check it out. You can be a charter member. It still comes with a third day money back guarantee. You don't like it. It doesn't do something for you. Guess what? You get your money back. So we take a look at the euro. You're gonna see the euro is at 105. Bottom line, we bring this up. And I remember this because I started the Gold Report when the dollar was 121. And the euro was 87, which is high double comprehend. But guess what? You know, you wanna go take a vacation at some point. Well, there's the, oh my God, that's 67. I don't remember that. Yeah, it was 82. 82 and two. So that was 2000. That was 2000. So I started it right there. Yeah, there it is, 83. You know, bottom line, that's what's happening. And we get this break. So the euro right now is at 105. If you get 103, bottom line, you are gonna get downtown. We go take a look at a few of the miners out here. Some of the Tigers are looking at the miners and said they're backing down with light volume. And let's go take a look at an eco-eagle first. Take a look at an eco-eagle. Yeah, it is backing down with light volume. I would, you're gonna have to be really careful here, man. Even in the gold market. Because the gold hasn't responded that like it should. Well, not like it should. There's no such thing as like it should, okay? It's responded like it's supposed to. You know, buying and selling, okay? My point is this. You have inflation raging. Gold hasn't broken down, but yet it can't catch a bit. That being said, if this dollar goes to 121, we're gonna see gold go low. Yeah, the correlation is direct. That's the real bottom line. Dow industrial is right now off of 475. We get the NASDAQ off 332. S&Ps are off 76. We have the, you know, Platinum's interesting. Platinum is having a hot, not a hot time. Platinum just, basically not only just rejected price. I like how it kinda rejected price. We'll see where the baby shakes out. But the dollar's the number to keep your eye on, folks. Check out Teddy's new Forex report. What he has in there is Forex. He has the, all the pairs. He has the dollar. He has oil and he has interest rates. You wanna know where they're at, folks. Stay right there. We'll come right back.


I figure I should come down here before I fall off. Probably the best idea. We'll give a couple more minutes. Most folks, I think, when being given the privilege of a 30-minute session, put slides out. I put slides in.  And most likely I will annoy some of you. So I apologize for that in advance. But the benefit is that what I hope the benefit is, is that this deck will actually be useful and have quite a bit more substance than we would have ordinarily been able to cover in a 30-minute presentation. So basically I'm cheating. But hopefully it is for everyone's benefit. I really tried to cut some slides out. So I've been known to quite like that. Okay. Everybody ready? Yes. Okay. Here we go. So 30 minutes to actual strategies. This has been given in various formats the first time in a 30-minute presentation. The longest in a day-long presentation recently in Texas. But the point here is really very simple. That we can do better, especially help our stakeholders and decision makers do better when we go through a normally painful process of being audited. Okay. If they still be painful, by the end of this presentation, just a prospect of it. But hopefully we won't be as fearful of it. And hopefully my slides, thing above thing, will advance. But no, I would deny it. So...


That was good. Let's get the bill. Excuse me? Yes, sir? I can't. The check? No, I just wanted to finish writing your novel so that I can read it. Oh, I have three chapters left to write. Hey.

Would be nice for a change. Check, please. What are you doing? Checking myself. All right. Left. That's going to be a long day. Up. Down. Up. Down. Funcure. Up. Pay. Okay, Bill. You're funny. Would you like to pay my cash? No. I want to pay my tools. That'll be one stool and a half. Keep the change. Pay. See? Salt. You won't catch up on me. Or you're going to let me? No, because I'm a cruel human being. Are you mustardid? That's fine. Things up for all seasons. Just for the spring roll. Okay, you win. Turf. Hi. It's just summer. Rise this. It's automatic. This is getting really cringey. So are you going to pay? No. I'm winning, so check. Mate. Are you sure?


Hello friends. Let's discuss the following question. It says integrate the following function. The given function is x squared upon 2 plus 3 x cube whole cube. Let us now proceed on with this solution and let I be the integral x squared upon 2 plus 3 x cube whole cube dx. Now, how we see that the derivative of 2 plus 3 x cube is 9 x square which contains x square. So we put 2 plus 3 x cube equal to t. So dt by dx is equal to 9 x square. So this implies dt is equal to 9 x square dx and this implies x square dx is equal to dt by 9. Now x square into dx is dt by 9 and 2 plus 3 x cube is t. So substituting all these values in the integral, the integral i becomes 1 upon t cube dt upon 9, which is again equal to 1 by 9 integral t to the power minus 3 dt and the integral of this is 1 by 9 into t to the power minus 3 plus 1 upon minus 3 plus 1 plus c, where c is the constant of integration. So this is equal to 1 by 9 into t to the power minus 2 upon minus 2 plus c. Now t is 2 plus 3 x cube. So substitute it. We have minus 1 upon 18 2 plus 3 x cube to the power minus 2 plus c, which is again equal to minus 1 upon 18 into 2 plus 3 x cube whole square plus c. Hence the integral of the given function is minus 1 upon 18 into 2 plus 3 x cube whole square plus c. And this completes the question and the session. Bye for now. Take care and have a good day.


What is problem folks welcome to another video so uh you know I went to Florida Like last week and guess what we filmed another video and I did not film an intro or anything And I kind of noticed that and so I was like oh crap we got to film an intro right now So that's what we're doing well anyways you guys are clicking on this video You guys are probably wondering Noah where is the giveaway winners?

I've been throwing a lot I couldn't really rip it through the grass. It's a super shallow flat There's not really much room.  I think the pink fluke might do the job It's going to get through that grass, you know, so leave this approach very shallow water I think the fluke's going to get the job done. We're still going to throw this chatter bait as well But we're going to go back out there and see if we can cut some fish on these two baits Um, I think this is going to be a real it's going to be a better option than this trap Going through that grass. That's super shallow. So let's get out there.  Look at that, baby. Oh, man. Look how I ate that chatter bait That was perfect. I know exactly how to catch them now Uh, we just been out here for a few minutes cast this chatter bait out there Frickin munchin Frickin munchin that is a quality pet. It's like I'll stop you. That is that's what you call a little photo fish right there Beautiful guy. It's peeing all over the place.  Let's see if we can get back in there and catch another one Money That's a big one too God right when you stroke it Oh man, golly, man This is crazy It's a lot like Florida Look at the colors on that fish guys. That's a beautiful bass. You're bleeding a little bit I don't know why he's bleeding. I got him on top of the mouth But another pretty little bass on chatter bait nothing really big Right when you stroke it every time they just load up on that thing. They're really liking this chatter bait through that grass This is unreal unreal Guys this is like two cast later I don't know All quality I mean, look how they're eating it guys. You tell me they don't want the chatter bait right now I mean, they're just choking it This is literally and this is like one of my favorite baits a trap in the chatter bait My favorite bait to fish and to be catching them on a chatter bait right now. Oh, that's just so much fun All right, buddy. What a beautiful bass look at the colors on him. Let's get back out there He's got me in that grass. I saw his fin He's right there. See him He's got a bucket of salad on him so this is To tell you guys what i'm doing right now with this chatter bait We're ripping it through this grass out here on this flat Right when you rip it through this when they grab it and that's You got oh my god I got him Okay Look at these grassy florida fish catching some florida bass out of this grass on some chatter baits. You cannot beat that Jump I cannot believe you're sitting here texting on the phone while fish are choking a chatter bait I'll continue to catch them. I'll continue to catch these little fat florida bass on the chatter bait All right.  It's probably the most fun fishing i've had in a minute I do not get to fish a chatter bait in grass too often. All right jimbo They're all about the same size or I just can't seem to find these big females out there, but Still pretty you're choking that chatter bait All right guys, so I'm actually putting a bigger swim bait on the back of this thing. I want to see if I can catch a bigger one I don't know if that's gonna make a difference or not, but I'm kind of curious See if a bigger bass hit that bigger swim bait on the back of this chatter bait Oh god, that thing makes this thing's huge. How about to say I haven't had a bite on that big one yet But it's a little guy and he literally chokes it. I mean look at that. It was literally in the back It was throat people That's a big swim bait and look at that That's like the smallest one today.  I cannot believe god. I got slammed again guys This is insane. I'm gonna find a stacked out here The wind is so bad and I'm hoping I'm blocking all the wind It's like killing my back right now This is a huge cold front blowing in right now and these fish are just We're sitting in the right spot casting. Oh, yeah.  That's like a four pounder Are you kidding me? Guys, I just lost a four pounder.  I think I got to see him really good that last jump I guess we just gotta keep casting I guess there is some bigger fish out here Oh, I'm so mad about that.  We're like smacking these fish They are loving this big swim bait too. I feel like that's why that bigger one bit it This is insane Oh Miss that fish are stacked out here. Let's see if we can get them this time There he is got him that time They are stacked right here guys I literally caught five fish in like ten casts And they were choking this chatter bait. I literally had one on the cast before.  I'm staying in the same spot just casting around this corner where there's winds whipping We're just going to continue To be my cast out here. They are just stacked And they are really stacked around this corner feeding on a ton of bait I'm gonna cast out there because I'm trying to keep my wind to this or this wind to my back They're probably stacked right where I just casted I've yet to cast right there Let's see So many fish out here chewing always huge. Oh my god. Yes. Yes Oh, yeah Yes He ain't that big He about three pounds That is insane. You choke that chatter bait guys. Look at that one. That's the best one today.  All right jimbo. Thank you for buying buddy Biggest today you get a reward Yeah, there he is I think baby hit that big swan bait Why did you bite? I'm slipping Why did you bite?

I'm calling it.   All right, buddy Barely There you go.    I love this Pretty much what i'm doing is i'm just you know throwing this bait out here and just you know Reeling it above this grass on this flat super shallow, you know when I hit grass I stroke my rod up That's usually when they hit it, you know when you're going over that grass and Throw that grass right off that bait That's when they've been hammering it usually every time you got all this wind pushing by creating this ripple on this water It's just making that bite so much better And they're just stacked out here.   I know you're behind it. Oh, yep. Oh, it's a good one Unbelievable look at that. What did I just say? Kick that grass off that bait and this big bass. He just cannot stand it He hit me literally. I didn't move my bait That's a good one too. Look at him. I never moved my bait I don't know if you guys saw that but by the time my bait hit the water He already had it in his mouth. Look at him choke it too. Guys. I didn't even move my bait I didn't move my bait. He already had it That is awesome right there. It's been back out there. See if there's another one. It's going to eat it the same way Tony my bait hit the water and he just had it in his mouth Must just I must have just nailed him Right on there's another one Oh man. Oh gosh That's a better one guys. You cannot beat this Oh man, look at this Let's get your butt up in here, baby This next cast guys You cannot beat this hit that like button guys if you're enjoying this video as much as I am Let's beam another one out there.

I always spit it like two pounds about the same as that last one That is just unbelievable.  That's pretty much three fish in four casts. Can we get can we get another one? Switch over to a small trailer My other big one is falling off. Let's see if we get more bites on it Turn my back to the wind Trying to minimize this wind noise guys by turning my back into it.  See you Jim They're either jimmy jim or jimbo or jimbob jimbob's big boy There he is. Oh man I gotta turn my back. This is so awkward Jesus man. Did he got grass?

He actually turned out to be a really cool dude. And- I'm just kidding.  Welcome back! So the NFL Combine, I spent so much time preparing for it. But some things, you can't ever say you're fully ready for. That's how the week felt for me.  I can't even hear the guy. Is he supposed to be talking? Force Big Team? I'm gonna let fate decide.  If you knew where you last saw them, they wouldn't be lost now, would they? Why does Rich Eisen get a good face scan and I look like a fucking- Talk of your next broadcast, aren't I?  Come on. I thought it was pretty good. Jesus Christ. I want to die listening to this. Maybe not your best, but tell you what, you let me wear your cleats. I'll laugh at any joke you have. I mean, seriously, I'm- Why does Rich Eisen have cleats? What's the verdict? Oh my God, Rich! We have the same size car! Perfect fit, but honestly- Okay, now I'm gonna lie. As I was editing this video, I realized how shitty and pointless this whole dialogue is, so I'm gonna skip all of it. If you're super interested in it, go play through it yourself or watch a different YouTuber. I'm sorry, I can't make you sit through this. Let's go. We got the combine. I'll be your tour guide as we meet the next crop of- We're gonna start things off with my personal favorite, the event that can break the spirit of any man. The 40-yard- Papamise! MSU Quarterback. Let's get this shmoney. Wait. What am I supposed to do?  Oh, I still ran a 446? Damn. That's not bad at all. Am I supposed to click it as soon as I see it? Is that like the thing here? I'd take a 446. I'm glad this is simple.  Is this the same button every time? Yeah, and the next one's Y, right? Oh, okay. Well, good. I got the exact same goddamn time. So it's RTXY, right? That's it? All right, sweet. That ain't bad. I can do that. I can throw bullets. Meigs. Rifle. Shmoney. Oh, out route. Got it. Got it. Shmoney.  Are you kidding? How did I...? Okay. Okay. Man, I didn't even do that. If you'd go up like that and miss this box, I'm gonna be so mad at you. Oh my god, where are you throwing Papamigues? That was not elite. 7 out of 10. I don't know, man.  I don't want you in my shot here. Why am I getting it? Who bears? Everything's great, coach. Thank you, sir. What do you mean thank you, sir?  No! No!   And I'm just getting confirmation that the pick is in. Let's take it to the podium to see who the next pick of the draft is gonna be. Oh my god. You know, everyone in my comments said don't let fate decide. Look at that smile.  Also, everyone said don't do let fate decide and here I am. Wait a second, can I actually see how good I am now? This is kind of important.  I don't want to hear you. All right, so I have Superstar X Factor development. That's dope. I'm a strong arm. Yo, why am I a strong arm though? The game asked me earlier what type of QB I wanted to be and I said I emulate Lamar Jackson, which would be scrambler, right? Or at least improviser, why am I a strong arm? I have 97th throw power? What? I have 97th throw power. What's my speed? I can't even... I have 65 speed? Is this a joke?  All right, so all I can get right now is conductor. So the big question I have for this year is will this rookie sensation succumb to the hype or will he rise to the top? Guess we'll find out soon enough after the week one games get underway. The guy could not have more obviously read that off of some shitty EA script that they handed him. Being such a high draft pick comes at a cost. Mainly, everyone expecting you to resurrect the franchise. What helped you adjust to NSO?  Where is that option? Practice hard, follow team captain, the playbook?  The playbook, sure. I must have carried my playbook with me everywhere. I must have carried my playbook together. I had to know everyone's responsibilities. It's not easy being a rookie. The excitement, the pressure, fanfare, the interviews, draft process. Plus, there's a lot of players banking on you to make them successful too.  I want to do what James Harden does. Meet teammates. I don't know if I'm supposed to be hearing this audio but I can't hear anything. It was still early days, but my teammates and I were getting to know each other. Building the bonds that would keep us strong and competitive through the coming season.   How about that? This is so annoying. It really is so annoying that they default me to strong arm. I want to be a scrambler. Even if I upgrade scrambler though, it's probably... Is it ever going to make my speed go any higher? They're on the run, they're on the short break sack. Yeah, I don't know if my speed level will go higher though. Somehow I'm at a Delaware state despite the fact that I put MSU right at the start of this. Okay. Oh, wait a second.  I can finally change the head.  I'm going to go with this one. Kind of looks like an Asian chick, but it's better than what I had. Hey, hey! It's Coach the Goat! Hey, mees. Hope you haven't forgotten your old high school coach. Hi, Leanne. I fell off some job deal with a rough meaty Dave. No doubt the guys that I can take those too. Got it from you, coach. You're stud. Aw. Alright, it's time to let me play some football. Wow, I'm playing the Lions? Wait, that's so depressing. Don't let me play the Lions. This is why I should not have let fate decide it, dude. Well, they beat us in rushing yards. Does that count for anything? Look, it's Stafford. Sorry, bro. I guess it makes sense they put us on the bears because the bears desperately need a QB. Deliver the win. You got 2,500 XP, 250 legacy. I remember that day. The game plan flowed through you, but everyone has someone they can lean on. Which teammate helped you the most? Mm. Jimmy Graham is my safety man, but Alan Robinson did have 10 touchdowns. I'm going to go Alan Robinson here. I got one skill point for that in 3,009. I don't get the progression here. 16 passing touchdowns is 2,000 XP. Okay. Are they going to tell me how I unlock these other abilities? Or are they just going to randomly unlock? Slight of hand, I unlocked. Alright, cool. And I already have conductor, and I don't have anything here. Alright, boys. I'm going to end this one off on that. I'm not 100% sure if I'll continue this series, but if you guys really like it, I will. I think the most fun part of the series is watching the silly cutscenes and making fun of them. I don't think it'll be fun to watch me put 118 points on every team I play. And then obviously get MVP, obviously get Rikki the year. But that's up to you guys. So I appreciate you watching this series. It was actually really fun. I didn't expect it to be this much fun. But hey, I love you boys. Thanks for watching as always. And I'll see you in the next video. Peace out.


Welcome to Start at School Crochet. This is Tasha. Today's tutorial, we're going to learn the half treble crochet stitch and this half treble is basically a double crochet and a half double crochet mixed together. So you can see I've done a little swatch here and I've worked in both loops of each row and you can see how it looks on both sides very similar. Steps we take to create a half treble crochet, first we're going to yarn over twice as if you were creating a treble crochet then you're going to insert your hook into this next stitch, grab your yarn and pull up a loop then you're going to yarn over and pull through two, yarn over and pull through all three loops on your hook. So you created half of a double and a full half double crochet so that's why they call it a half treble. So yarn over twice, insert your hook in the next stitch, yarn over, pull up a loop, grab your yarn, pull through two, grab it and pull through all three. Let's do it one more time and one more time for posterity. All right so that's it. If you have any questions or you'd like me to do a video tutorial for you please leave me a comment down below and I'm using Heartland by Lion Brand and I'll leave a link for this yarn down in the description. All right y'all take care and happy crocheting!


My name is Vincent Martin and I'm currently a PhD student at Georgia Tech in Human Center Computing in a classroom. Assistive technology is really wide and varied, but it's also everywhere. It's now ubiquitous.  Every last one of those smartphones and tablets have assistive technology built into them. As it is with people with all types of disabilities, people with the same disability also access information differently. For example, I'm totally blind and I primarily utilize my computers and I say that because I have five or six different computers with different operating systems and I utilize them different ways. I access a lot using a variety of screen reading programs with hardware and software based synthesizers. Other people with different disabilities may utilize various types of assistive technology differently. Words appear. Our technology for equal access. Sensory impairments. I'm Eric and I have a visual impairment called Stargarts and it's a macular degeneration which affects the center of my vision, so it makes it really hard to read fine print and see details. So I use the sides of my eyes to see more and the periphery. Zoom text The main piece of assistive technology that I use on the computer is Zoom text which is a screen magnifier that allows me to make everything on the computer screen as big or as small as I need it depending upon what I'm reading. There's also a built-in screen reader on Zoom text which I can also use to help read documents because my eyes get tired really easily. I use a closed caption TV monitor that I have on my desk that allows me to see the board and what is being projected on the board by the teacher. Hi, I'm Mike. My disability is that I am visually impaired. I can see things up close but for the way it gets blurry. I use a whole bunch of different technologies in my daily life. My smartphone works brilliantly for what I need it to. It has a whole bunch of different apps on it that will help me in my day-to-day life. I have voice stream reader which is an input app so you can switch over different types of media and it will allow it to be read aloud to me. Lyceum Lyceum to State July 19th, 2016 5 0 p.m. That's what the sign says. Scanning is very important for somebody with a visual impairment because there are a lot of printed materials in the world in general that are very not visually impaired friendly or not blind friendly. Hi, my name is Jessie and I'm a 4th year student at the University of Washington. I'm a student in informatics with a minor in diversity and I get to find my son as a staff. So as a staff technology I use on a cochlear implant which is my own position. I use an app system which I give to my professor so that I can hear the professor more directly through my cochlear implant. It's like a microphone. I do not accommodate and use almost every day is called C-A-R-T which scans for communication access real time and so what it is is capturing it and give that real time captioning that I can read the transcript on the screen while your professor is talking in real time. Words appear. Mobility impairments. Hello, my name is Cameron and I have a disability called cerebral palsy. It affects me because my legs aren't able to work as well as others and it's not as efficient. In the course of my day as a student I use technology such as Dragon and Dragon is basically a speech input system that will write for me as I speak into it and that helps me become more efficient. He wears a headset, Mike. This is an example of how I use Dragon. R-E-M sleep is when the body goes through multiple stages. The text appears on his screen. R-E-M sleep has four stages. Hello, my name is Blake. I graduated from the University of Washington Tacoma with a Bachelor of Arts in Urban Studies. I have cerebral palsy which means I cannot take notes very quickly. For me quality education includes access to instructors presentations, notes or outlines of the lectures so that I have high quality notes from class lectures and discussions. In college I used this DynaVox to communicate with my peers and professors. I used word predictive software called co-writer to speed up my typing on assignments and papers. Co-writer predicts words in a window as one is typing. My name is Teresa. I'm a high school student and after high school I plan on attending college and majoring in psychology and I was born without arms. I use a Bluetooth keyboard and a Bluetooth mouse so that I have full accessibility and I'm able to write down notes and catch everything that I need to catch in a more efficient way. Without my arms I have the keyboard and the mouse on the floor and then the monitor is just sitting on my table in my classroom. When I'm typing notes I can usually type pretty fast just because of adrenaline but I'm not fast as fast as someone with arms. My name is John. I have a student who works for me.  Hi, my name is Caleb and I am a sophomore here at the University of Washington where I am double majoring in Law Society and Justice and Disability Studies. And I want to take that and eventually become a disability rights lawyer. And I was born a congenital amputee missing three of my limbs. I use a Surface Pro 3 as one of my assistive technologies. Most people wouldn't necessarily see that as an assistive technology since it's something that many people in classes have. But for me it is an assistive technology because it's lightweight enough that I can lift it myself, which is very nice. And it has a keyboard that is smaller, which is also something that's nice for me since I do all my typing with a single hand rather than having two hands. Words appear. Learning Disabilities Hello, I'm Matthew. I have ADD. I have mild ASD and I've been diagnosed with mild Aspergers. I use co-writer. It's a word prediction program. There's six words you can choose from by hitting the number key. It's the word you select out. I would use it mostly in my classes for very important papers where I definitely would need to get the grammar correctly. Or the words correctly as well, depending because I struggle with spelling at times. Matthew pulls a wheeled bag, carries a briefcase, and wears a backpack. I am Jada. My disability is ADD and dyslexia. So with ADD I have a hard time sitting still for a long period of time. I use a document scanner. The scanner helps me by actually reading the content that is on a book instead of having read it by yourself. So with the scanner you set it up and then you launch the program that is in the computer. Then you can highlight or have it read to you. Even though I'll study them and study them and study them. She places a paper under the scanner. I tend to forget. This will help me by making it easier so that I can have the digital copy of it on the computer and have it read to me. And then I can start writing notes along with it as it's reading it to me. Just depending on your disability it really depends how you learn. I'm still definitely trying to learn about my disability a little bit more too. Words appear. Final thoughts. The one thing I would say about assistive technology is that don't be afraid to try it, especially in high school and middle school. Because there are so many different options out there and there are so many new things. That if you just stick with what you have you might not be doing it the most efficient way possible. So that when you go to college and your future careers you'll know everything that you need in the best ways to get everything done. My name is Cheryl Burgstahler and I direct accessible technology services at the University of Washington in Seattle. Our services also reach out to our branch campuses in Bothell and Tacoma. It's essential that people with disabilities have access to assistive technology but that's not the end of the story. In order for them to be effective users of technology, the technology that other people develop like websites and software and PDF files and so forth must be designed in such a way that they can use it with their assistive technology.
