 Good morning everyone. My name is Teebo Scheffer. I'm an engineer at provenance. So we're a software company maybe some of you heard of us already. We're based in London in the UK and basically to sum it up the kind of the vision behind provenance is that every great product should come with provenance and what that means is towards trustworthy information and accessible information about the origin and the journey and the impact of that product and basically the way that we deliver on this vision is that we provide a platform for businesses to be more transparent and share data across the supply chain and as well as with consumers so that's both an access for businesses to share with also consumer app that consumer can access to learn more about the supply chain and the great products that are being made So one aspect of this platform has to do with storytelling because we believe that just disclosing how you make your products and the craft that's put into them is already a good going the right direction in terms of transparency but obviously what I'm going to be presenting today is more of a the verifiable aspects of what we what the platform allows So we Almost everything we do at provenance around that is linked to the to the concept of verifiable claim So I'm sure many of you are familiar with the The concept of an identity framework So there's been a few presentation at Defconn already on that and there are many initiatives going on the concept that individuals could control Their identity and once they control their identity make claims about themselves and then have those claims Being verified by third parties or different verification methods So for example, you could want to prove that you are over a certain age to access a particular service And then you can have that verified by let's say a bank or or a peer-to-peer Verification method the important point here is that a claim and a verification are two different things and that In what we do we try to keep the verification method as generic as possible so that People can integrate their own verification methods with the system And as you can see what we are trying to do is taking this concept of verifiable claims On individuals and bring that to the supply chain. I means to businesses and their products So first let's let's look at businesses. What what type of claims could a business could a business Make so one example that you could have is that as a business you want to claim That you're independent or that you're a family owned and in this case The way to verify that could be for example to link to your business registration That's exposed by the government especially in the UK. There's companies house that exposes this information And that can act as a verification that you are for example not owned by another bigger company You could have other verification methods that could be linked that could be based on Consumers vetting for the businesses that they know in the same way in the same kind of way that Tripadvisor or Yelp functions Of course not all verification methods are equal and they provide different levels of trust And different levels of confidence on the veracity of the claim Another type of claim that that's that's really common in supply chains is that of certification And in this field what we what we did is working with the social station Which is the the first which is the biggest Organic search fire in the UK and working with them to bring their certification to the digital age So what what what does that mean? What's I think we need a bit of context around what a Certification process looks like today for a sustainability Certification so basically as a business if you want to be certified organic you're going to apply for a certification Obviously pay a fee Which can be quite expensive sometimes for small businesses Then you're going to be audited by an independent Auditor and if all if all goes well You're going to be awarded a certification what that means in terms of data is that there's just another record In the solar association database that keeps track of all certifications And the way as a business you are going to be able to prove that is through PDF that is sent to you. It's basically a certificate of organic So when you're going to be transacting with your business partners and you need to prove to them that your search for it organic You end up moving back and forth PDFs in the supply chain From the point of view of the consumer the interaction that the consumer would have with a sustainability Certification most of the time is either through just a logo on pack Or it's going to be a static JPEG on a website for example So that's where we saw some opportunities to make that better and make it more interactive and and interoperable So what we did is connecting the solar association Certification database to the Ethereum blockchain so that directly on the Ethereum blockchain You could check the status of any certification for any Licensee of the soil Association Creating a kind of a digital version of that certification The outcome of this project was that we created material Both for point of sale so in the form of connected labels that you that consumers can Can scan either by NFC or in QR codes and we're very excited that NFC is now being supported by by the new version of iOS So that consumers can access directly is to this information at the point of sale and When it comes to digital space, we created embeds that Brands that were certified organic can integrate in their online store So that consumers again can access and verify the status of the certification on top of that the fact that We provided those tools to kind of augment the certification allowed to raise awareness on what the certification actually means and what it stands for Because we believe that just just a logo on pack is not enough to convey What the audit process was and and what actually the compliance look looks like So moving from businesses what we're trying to do is also to Have verifiable claims on products So when when you think about a product one verifiable claim that you could have is for example that it's free of a particular allergen and a way to verify that Could be either by normal audits, but also increasingly and and it's getting cheaper Through things like DNA testing that we're also looking at but in this context We saw that a very useful tool to prove claims about products was that of a tracking system along the supply chain That's why that's we we developed a way to Track assets along supply chain and tested that in in different pilots So maybe someone in the room saw our our piece on tuna supply chain We basically Studied tuna supply a sustainable tuna supply chain over in Indonesia and basically the setup was that there there's there was a certification over in Indonesia according to sustainability Practices that was certifying specific fishermen that could That that could produce tuna that was certified So that was going great, but the problem with this was that when looking at the supply chain there were there was way more fish being sold at the end of supply chain with the certification then There was certifications being issued at the start So basically what we were trying to solve with and in this particular project was the double-spending of Search of system of the certification claims on tuna So what we built for that was an interface for fishermen to register their catch Via a batch of tuna using SMS services Because in the environment we were operating in there was even no smartphone To to use so it had to to go through SMS Those catches would be linked to the certification that the fishermen had been awarded before and then they were able to transfer ownership of this These batches down the supply chain and at each step a transfer would be a handshake between this sender and the receiver agreeing on The details about the fish so that can be a size of the batch can be the certification itself and so on Another Project that we that we did in supply chains was with co-op, which is the fifth biggest supermarket chain over in the UK and for that we extended our our system our tracking system to support more features such as supporting different units using IPFS metadata on the assets more data on the assets as well as Batching splitting of batches transformation from one asset to another To have to to allow for more flexibility in supply chains So what we did with co-op is and what is interesting in comparison with the previous Example is that we were focusing on claims of proof of origin So we were trying to prove that Some products that were sold by a co-op were actually made in the UK So that was that was a claim where we're going for and for that we went in co-op supply chain and and and obviously it was a More it had some degree of digitization So compared to the previous one where it was just normal phones. They have earpiece They have systems in supply chains So kind of the challenge and the learnings that we had through this experience is how to integrate with those with the systems and the result of that was Was that we created an interface for consumers to access the the journey of This product so in this case it was about flowers, but we also Considered all their products and we integrated that in to the co-op consumer app so that consumer can directly Discover this and explore the the journey of the products that were being sold So the next the next question that we asked was how how we can incentivize good behavior in this system because I'm sure most of you recognize that it's it's not a completely Trustless system and and they can be breaches and and and honest Players and what we recognize is that Linking this infrastructure for trust with the incentives of supply chain, especially financial incentives Could be a way To to incentivize good behavior. So kind of the MVP version of that that we Developed Recently was in the frame of a collaboration that we did with a Dutch NGO called Fairfield So in this case we were focusing on Coconut supply chains in Indonesia so again Indonesia And the claim that we were trying to prove was the fairer payments to the farmer At the first stage of the of the chain So I'm sure you're familiar with the concept of fair trade, but in this case we're trying to do it in a completely real-time way and proved on on chain so the way it happened is that We provided again an interface through SMS services because again people didn't have access to smartphones where we were operating and We were enabling farmers to register the coconuts that they had harvested and as a batch and Then some of the handshakes in the supply chain Needed a proof of payment to actually happen and the way that Happened in practice is that whenever the next actor in the chain So that was the trader that came just after the farmer that harvested requested ownership of a particular asset the The farmer would get an SMS asking them if they got a particular amount that were that they were supposed to have got because supposed to be basically an exchange and Depending on the answer that The farmer would provide to this question the transfer would complete or be rejected So in terms of the amount that was in this message that the amount was determined by Fair food with which was this NGO based on a standard of living income so dependent on Different parameters including the size of the batch of coconuts obviously and What was quite interesting in this case is that we were trying to see if we could have some impact on the supply chain itself and actually among the set of farmers that that we considered a few of them actually Answered no to the to the question from the SMS and when we when we investigated It appeared that some of the farmers were actually only being paid a small deposit on their on their harvest And actually the fact that the system was in place and and that the the transfer couldn't be completed Led to the the actual payment to be to be made in in full So it was it was a first sign that we can have an impact on how supply chains operate So obviously that's that's still Kind of a first first iteration on how we could connect this set of Claims to Fat to incentives and supply chains And what we are starting to also look at now as a next iteration of that is how we can connect our system with trade finance and insurance so that as a business any transparency that any Transparency and claims that you make that makes your product more transparent should be rewarded in terms of Better access to capital or cheaper access to insurance and so on So we're gonna be starting some projects on that and we are sure have some Announcements you to make on on that soon So yeah, that was that was pretty much what we've going what what we've been doing in in the past month and Yeah, please reach out to me. Thank you very much for your attention
