A

With multiple use cases of nft, have you ever wondered of a digital receipt nft for bookkeeping? If this sounds interesting to you continue listening.

A

Welcome to p penny episode, 95 I'm Pooja ranjan wishing my fellow akiram Community a very happy 2023 in this nft special episode. Today we will talk about EIP, 5570, digital recep, non-fungible token and upcoming ethereum standard with author Sean Darcy eip-5570 is a standard track. Erc proposal documented on 1st September 2022 and currently is in draft status.

A

According to the proposal, this EIP proposes a standard schema for digital receipt of transactions.

A

Sean Darcy, the author of the proposed standard, is also a core Dev to different blockchain projects to know more about Sean and learn about eip-5570. Let me welcome him to the show. Thank you for joining us Sean.

B

How are we doing.

A

I'm doing good. Thank you. Thank you once again, Sean for joining us generally.

B

A

Generally speaking, we request our author to share a bit about their professional background, how they get into the ethereum ecosystem, and then we get into the presentation, so yeah now feel free to screen share. If you need to and yeah over to you.

B

Yeah, let's do it um so I'm here today. Talking about did you receive nfts um I have recently opened this ethereum uh protocol proposal and it is a broad level. High level schema for receipts and a good way to use them on the blockchain.

B

um A bit of background of ourself is I, am an ex accountant I up until covert times was working as tax and doing small business bookkeeping for uh Australians and then uh during covert. We got hit pretty hard, so I had some spare time spent that reviewing ethereum things, but the specifically Geth, and that ended up leading into a developer role with uh my current company oxen and on the side as well.

B

I do a lot of projects relating to accounting, um I'm the maintainer of go DB Ledger, which is a self-hosted accounting software um high level of that is.

B

It is a uh essentially if you took Geth itself ripped out the back end put in some double entry bookkeeping, and that is a whole I guess is me trying to automate the finance sort of side of things specifically for accountants um and then, as part of that I sort of realized that uh digital receipts play a core part in how we go about automating finance, and that eventually has led to this ethereum proposal, which is now up. uh It's ERC 5570.

B

uh It's currently in draft status and I am excited to talk about it, but it's uh essentially I want to talk about first before we go too much into it.

B

um About wire receipts are so important to automating the the finance industry as a whole, um and the background I sort of came was when I was working on the go DV Ledger stuff. Is you have to record your transactions in your financial software?

B

um Businesses do this every day uh they record their transactions are spent, and then they summarize that into a set of financials, which um eventually go into a tax return. It goes into a lot of places um and the classification of those transactions is often based off a receipt.

B

um If you are the person spending the money, you often know what you've spent your money on, but if you're getting someone else to classify it, you usually get like your account and choose anyone doing it. So they usually dig up a bunch of receipts to find out how to classify your transactions, um and this is what happened with me is I was trying to classify some transactions and got frustrated that my bank accounts didn't show this to me directly um and I'm like. Why?

B

Doesn't this directly exist within my bank statement and fortunately Us in the crypto uh industry have a bit of an advantage? Is we can build these things directly into blockchain, um which has led to this um ERC, so the receipts get used for a lot of places, not just in the like record keeping um when you're reimbursing people and when you're giving refunds to people.

B

You also need copies of these things um and, in general, they're, a bit of a pain to keep track of so having a digital way is always like better um and receipts are something that businesses are obligated to give um there's a bunch of legislation, specifically in Australia, it's kind of like over thirty dollars. You should be given a receipt to people, um at least in Australia.

B

This hasn't really been digitized, we're still getting physical receipts, I go to like the um the supermarket and at the end of the transaction they spit out a physical receipt. um Some businesses give you a digital copy, but.

A

B

Most of these digital copies are barely digital anyway, they're, mostly like PDFs, that get emailed to you and stuff and even then I'm kind of like I, don't really want to give you my email address like you're, just going to expand me with marketing now, um so this is always sort of leading to like how's a better way of doing this and one of the really good things about nfts is we have this metadata section uh where we store a bunch of bunch of information um and it's a it's a very, very good place to put receipt data, so we've already got if you look at the nft metadata extension, there's sort of three Fields where you require on an aft which is named description image, and this is given everything that afts are today and my uh like proposal that I'm sort of saying is we can.

B

We can also standardize a way to give um like a receipt schema and so there's a a fairly uninteresting schema to receipts. They are literally just a date with a list of items really and it's not super exciting. The schema itself, um I've defined one in the the ERC but I, don't think it's very um exciting. To be honest, there's not too much that's interesting in there um and we we can put that directly into the nft manager um and then I'm also saying like another good spot, I think to live in.

B

There is the signature of the receipt, so the vendor, who is uh giving you the receipt, say um Walmart or something they have their own signature, so they can digitally sign um the receipts. So when you have a copy of this receipt and that digital signature matches, you know that this digital signature is legitimate, um which is good for a variety of reasons. I think I'll discuss it a little bit later, though um so the the schema is uh defined in this uh proposal, not super interesting.

B

What is interesting is we are putting it in an nft, which means we link the transaction on the blockchain directly to the transaction information.

B

um And what what does this bring to ethereum? So the first of all the one that sort of excites me? Is it automates, our record, keeping um which is again leads back to the go DB Ledger sort of stuff? Is we can have a computer to scan these receipts um if you're running a business and you're buying things the the information is right there for the computer and then they can classify things, um but it also turns out that these receipts form the basis of a lot of other projects that you can do.

B

So if you have on the blockchain links to purchase history and um other businesses can have access to that. um But then, like this there's, some discussion I have a bit later on about encrypting stuff. So it's got some privacy elements to it. But if you want refunds- and if you want um like tradings and stuff, you can have the the receipts that are living on a chain, give you all the information you need to do that automatically.

B

So when you want to process those things, there's no uh I am sending a receipt to a person who has to look at the receipt and then generates the like uh reimbursement for you. It can all be done with a click their button and a computer can do it all, um and this is all of this is all possible, because the transaction contains all the information you need for your receipt data, and then this leads to some nice things too.

B

So you can kind of visualize like your metamask wallet and if you would open that up at the moment you got a big list of your transactions and sometimes there's not a lot of detail on what is going on there, um but you would be able to have that wallet, just click straight through to transaction data.

B

um It's like why keep a box of receipts when you can just um you can just click straight through to it in your digital wallet, which I think that's probably one of the more exciting things that like visually, you can see this existing and it should it's like why. Why should you go anywhere else, but your wallet to look for transaction data like it could live straight in at a mask?

B

um So so what does a transaction look like under this proposal?

B

um So you can? You can imagine going to a a vendor's website and you're purchasing a physical good.

B

um A blockchain transaction occurs um probably transferring some some tether or usdc over to the vendor, which is you paying for the purchase and then in that same transaction the vendor would be issuing you an nft, um but it's it's not like an nft like an artwork nft. This would just be purely containing the data of the transaction, um which is, which is why nfts are pretty exciting in general, because it's a like it's a token, a unique token and that's exactly what a receipt is in this case.

B

So this this nft has a URI that points to um a domain controlled by the vendor, so they would be maintaining the database of their receipts that they're issuing um when, when they process the purchase on the website, they've upload the details to their database and then they would Point their token URI to that.

B

um So, at a later date, the or immediately if you wanted, the customer can go straight to that token.

B

Uri look at the metadata of the transaction and it would contain the receipt um and then- and then, if the signature stuff is contains um because I mentioned a couple slides back, then you can save a copy directly to your file um and you you don't need to keep a copy of that online, but, like the vendor, might just for convenience View um and this- and this is sort of where the other interesting things we can do with the receipts is um in the industry.

B

I see everything's sort of just the details of the receipt um nothing's encrypted in here, but that's not to say that um there's there's other erc's I've seen coming out that detail. How you can encrypt uh nfts in that and I did see a couple that were very interesting. At the same time, I launched uh this um ERC, so this is not built into this ERC, but I very much think that that would be the default in the future.

B

But right now it's just like the clear text, details of it um and it's a signature field. um This again, my last traceability, so in in our um in Australia. If you want to purchase to be like a valid deduction in your tax returns, you're supposed to be able to provide a receipt- and one of the things you want is the Auditors to be able to like check that it's a real receipt- and this is what the digital signature would allow is like.

B

You would open up your receipt and you'd see a signature, verify that it matches um the public key of the uh the vendor, and then the third party would know that that's a valid receipt, so it'll be uh a valid deduction in that case, um and that's built into this as well. So that's sort of exciting.

B

um I've got a list here of um other resources that are sort of built along the way. um The long form article on medium is a very uh it's a bit more. It's pretty much exactly what I've been discussing here is. It just goes into details and the technical specs as well, uh and then, on top of that, there's a GitHub repository um this digital receipts ERC, which contains some example, smart contracts um and also a web app that can actually give out a digital receipt um and that that's been hosted at receipts.

B

Dot darcyfinancial.com, an example: did you receive from that website?

B

Is that top link, um and then I've also got down the bottom of YouTube video showing how to use it, um and you can kind of see if you were to go to this um this top link here, it's actually gives you uh nft image, so it takes what is in the nft metadata already and all the infrastructure we've got built for nft art and you can physically show that receipt in a form that looks good for humans already, so it it very much like gives you both the data that computers need and also the like, uh visual aspects that humans need.

B

So it it encompasses everything and it's sort of been like pretty exciting. um I.

B

Think there's a few questions that you dive into a bit more detail for this and I um I'm pretty excited to dive into them because they seem pretty interesting. um Did you want to start with those Buddha.

A

Yeah sure, thank you so much for presentation. This was great and obviously it gives a very good high level picture of what this proposal is all about and how this will be used. Yes, we do have a few other questions which will help us dive more into it. My first question, which is I, think a question for most of the people's mind is like: why do we need an on-chain receipt like a digital receipt which say, for example, if it's a transaction detail that we get it from etheridgecan.io?

A

Couldn't that be good enough to ensure the transaction? Is there.

B

Yeah so I guess um one of one of the things: that's it well, it sort of partially isn't on chain as well, because the the nft metadata is hosted by the vendor in the end in this case, so they they would have their website um and they would have, on top of it, a link to their database of the receipts, and then the on-chain stuff is um literally just the nft, and what is contained on chain is simply just the nft database that links the ID straight to the um the token URI.

B

So the stuff that's actually kept on chain is quite minimal. um I, don't I I, like there's, been a few discussions with this come up around this and how you should or shouldn't save the uh the data here and I. Think that in general is a very interesting and probably the most um like. The most unique thing about this proposal is how the digital receipt data is stored and I. Guess in general, it's like what is this, and how is this different to digital receipts in general um is is kind of like well.

B

This is a generosity. The Json scheme is not super interesting, but the the way the data is stored is the unique stuff and I'm saying here specifically that uh the data should be stored in a database hosted by the vendor, and then that is linked to uh the blockchain transaction through an nft and that differs to I. Guess a few of the digital receipts that exist um today. I, don't think they've got much traction, but there that would be.

B

There is essentially hosted database somewhere, and you give the customer a link to that data, which is the um essentially the token URI.

B

So the it's essentially the same, but the difference here is: we've got the nft um and that allows us to trace through the blockchain uh from the transaction itself, to the digital receipt data, and that Trace is something that's super useful um and as sort of mentioned before it means. When you open up your wallet, you can click straight to it.

B

um It means when you're, trying to automate the transactions. You have 100 confidence in this receipt data linking up to that transaction uh which which, if you break that link um that there becomes an element of uncertainty.

B

It's like has the person provided the correct receipt for this transaction I need to verify that, whereas, if it's already included in the transaction itself, there's no room for it to be wrong like you can only be linked to one and that one really should if it doesn't match the details, as in like um the amount doesn't match, then you're like okay, there's something wrong here, but if it links- and it's also the correct amount, then you're very confident that that transaction data is correct and my computer scripts that I'm trying to automate um my record keeping with, can just go from there.

B

It doesn't need to make a pop-up. It doesn't need to do anything that says. Oh, please, can you double check this receipt to make sure it's right. This seems a bit weird, um whereas if you don't have that link, it kind of becomes like a please enter your receipt URL here and then it needs to verify it, which is extra steps, and it's extra friction to automating your finances and that's primarily what I was excited about is like once that's gone, it's so easy.

A

That is wonderful, I mean. Definitely it helps to find any transaction history way more easier and convenient um and yeah Easy's number one good point of of this.

A

um I would like to uh ask you this coming from The Proposal itself, the description suggests that EIP 5570 to be non-fungible token, a digital recipe for physical purchases, where the metadata represents the Json reset. Is it limited to physical purchases, or it can be an extension to digital transactions model.

B

No, it's absolutely not limited, um so you can have your services recorded here and and a bunch of other things too, like um you could be recording the receipt for refunds and stuff um I, I, guess I've said like um physical Goods here, because it's probably the place where um ethereums doesn't keep a lot of data right now um the physical transactions occur, an amount gets transferred, but like what happened on the like actual physical side is done off chain and not recorded at all so I.

B

Guess it sort of just highlights here and it uh it probably could be improved that the transaction data contains stuff that isn't on chain right now and stuff. That actually is in the physical world, um and it's simply just highlighting that it's other information, this new, that's not already on the blockchain but 100 I'd, be using this for a receipt for my accounting services. If I was issuing it as well, so um it could be any anything. There's not not at all limited to physical Goods.

A

That is good to know. Probably um we could like mention it like it could be used. In addition to it is that this could be used for physical purchases as well like. Even if the product is not from the blockchain world, not from the digital world, we can still have the nft for that yeah.

B

A

All right you did mention about you know there could be multiple usage of that. We know that nfts are unique in itself or even the author, William and troiken, who proposed the e8721, did mention about it like it's kind of deep, the ownership that is being reflected with these unique token the nft. Could you maybe uh share a few other use cases where you think this particular EIP would be useful and I? Remember you mentioned about uh a demo. Maybe if there is something from there, we would like to share.

B

um So my demo is, um it is mostly just uh showing how the physical thing it literally just gives you a form and says hi. If you'd like to use this form, um you are welcome to do it and it will generate an nft for you uh yeah. So is that one up for you? Can you see that yes, yeah.

A

B

Is literally um the demo app that's been contained in that GitHub repository um and what it ends up doing is it gives you a preview of what the receipt will look like, um and it just gives you a bunch of um fields that you can fill out and some of those are already filled out and usually, when I'm using this one, I just sort of Click generate receipt.

B

um It goes through the go early test. Network, um you have to connect your wallet. I, don't have any ethernet right now to like demonstrate it, but it will generate this receipt on an nft.

B

um But what it does is this image that's saved on. It is literally this exact one. This web app um has some behind the scenes, generates the HTML to make an image and then that image is uploaded directly to um this nft editor, which is a bit unfortunate.

B

That's something I should double check that unfortunately, um and the web app sort of just demonstrates like what it actually ends up looking like, so you actually got a physical nft given to you, and it's got the um contents of that image and it's got the Json data there.

B

um Some other uses for this sort of spring up from like. uh If, if you had links to this on chain, um the other uses that would come out of it start coming from say, like I'm, a business who has sold a bunch of products, um but I also want to issue refunds for those products.

B

um So you say: you've bought your iPhone or something and you've paid for it in uh cryptocurrency and you've got this nft receipt for it. um But, like a week later, you want to get a refund for it. So the the details that they need to process that refund already exist um and are saved in your wallet.

B

So the refund could be done in literally one step by a computer, and then it would issue you the box or something that you would need to return it, um and- and this is opposed to saying like right now, if you wanted to get a refund for some object, you usually have to go to a person, a retailer. You say: here's my box um and here's a copy of my receipt.

B

I did this a couple weeks ago and it's broken um and and if they're, maybe on top of it, maybe there's a web form to do. First of all, where you upload those things um and I guess like a human, would review them behind scenes, I'm, not fully sure how they work in real life. But this is a step toward automating all that, because the data is already available and it's already verified that it came from the vendor and it's already verified that it went to you.

B

It went into your blockchain, so you can prove that you're, the person that received it.

B

um So it's it's stuff like that that when we've got this data available, um businesses and projects can sort of Leverage that data existing and they can start doing interesting things and the refund is a good one. um Like again, I've come from it from I want to automate my record keeping side of things um and I'm sure. There's plenty more I've had a couple. People reach out about projects um I, don't want to spoil their beans too much but yeah. It's um it's a lot of data that we we sort of want on chain.

B

Like you can imagine, a transaction has like two sides of it: one is giving money, uh the other is giving like a good or service to the customer, and we represent currently only one side of that transaction in the blockchain itself. Right now, which is the funds being transferred and I'm saying, we should also contain the details of the goods or services being exchanged.

B

um There is a privacy element there, which is why I guess in future that I'll be linking this with another EIP that like encrypts at all um but yeah. Your transaction should contain both sides of this transaction and then, once that does available, we can.

B

We can start doing more interesting things and leveraging that data in the same way that once we have access to the transaction, ethereum transaction containing, like the amounts of stuff, a digital, um a digital blockchain's, a lot better than physical cash, I guess is there's a lot of it in just having that. We've already seen that um it's the same here with the receipts as we start leveraging that digital side of things and existing of chain- and we can build interesting things on top of it.

A

That is quite interesting and you brought two important points when it comes to digital recep or the receipt on blockchain. One is the encryption part that the security privacy and the other one is uh the storage part you did mention about security and privacy there would there could be another eib which they linked with this um I would be curious to hear your thoughts about the storage part.

A

um I. Remember mentioning I. Remember you mentioning about putting minimal data on chain. So what is the proposed method of storing yeah.

B

Yeah, um so the storage is and and I very much think that this is. um This is a topic that, like a lot of people, have um opinions about and like there's definitely was a lot of discussion about how you should store it. um I am pretty confident in saying that the better way to do it is the same way we do nft metadata, um which is, which is the data stored off chain, but the link to it exists on chain. So we have our.

B

uh The nft contract only really contains the the single database that links to the address um and then off chain. We store on a database that is controlled by the vendor, so in this web app here um the back end. Also, when you click generate, um it adds that receipt to its backend um and then the nft Dada is viewed via the token URI on the smart contract, so I I think that is by far the most efficient way of doing this.

B

um There is some discussion there about what happens if the vendor deletes that information, which which sort of is the same discussion as what happens if a an artwork nft project deletes their database um and the the I guess my sort of thoughts on that is.

B

If, if we have a signature on the receipt, so the receipt's data is signed, you can digitally copy that and save it to your own database at the time of purchase, um which I guess is like the modern equivalent of taking a photo of your physical receipt um and then keeping that in a safe place anyway, because you'll receipt in the real world like a physical printed out, one gets damaged. They've got those Sun exposed sort of like paper that turns blue.

B

If you leave it out too long so like they get damaged after a certain time and they disappear and yeah you end up wanting to use the digital copy that you've made rather than the original and here's the same. It's kind of like you would just copy the data directly into your own into a file into a database.

B

um In my case, I'd say: go DB Ledger! Should be the one that records it as the data, um and you should have the software doing it directly um and then, after a certain point, receipts sort of stop needing to exist anyway, um like a transaction, that's over seven years old uh in Australia, you don't even need it for the ATO, it's too old, it's um no one really cares about it, so you're not going to get questioned about it, it's after a certain point, so it's kind of like if the if the data disappears.

B

After that point, there's probably no harm done and we don't want that sort of permanently clogging up the chain either. um The counter argument to that, however, are people who you reckon it should exist on chained. um Therefore, it's immutable, therefore it's permanent, which which has a lot of like uh positives.

B

um Mostly it's just like. Oh what? If someone fraudulently changes the data- um and in this case it's obviously the vendor who's um capable of doing that, but uh I guess it also sort of brings up a change of what happens if it's incorrect in the first place like what? If what if something comes up and the receipt is wrong- and it's like well now- it's locked on chain- you can't change it, which seems pretty harsh, considering like human areas, sometimes occur, um but like you can amend things.

B

So it's not too big of a deal, but then you then you're starting to add like well now I've added um but like maybe a kilobyte of information to blockchain just for a couple receipts and that that doesn't seem super a great situation to be clogging up the blockchain. With that data, it can exist off-chain. It gives you some lenience to if the vendor wants to change it because there's some mistakes um and it it gives an opportunity for the data to disappear in the future.

B

If, um if it's 15 years later, and no one really wants to look at that receipt anymore, it's probably probably Fair, um however, that it does sort of bring up that security, sort of um element uh and I guess. My response to you know what, if the vendor tries to change it and tries to be fraudulent there and I guess, my point is like they still can be fraudulent anyway, like the original transaction is created by them.

B

um I guess that's! That's kind of um it's! It's still possible in the real world like what, if someone gave you a receipt and said, oh you, you only actually purchased a chocolate bar instead of your PlayStation 5, or something like that. um It's it's like! Well, it doesn't actually benefit the business to do that in a lot of ways.

B

So the the incentives are not really aligned for a business to fraudulently create receipts for you, so I think it's a minimal sort of risk, um but whereas the bigger risk is probably errors being generated, so you want to give some forgiveness and that all leads to saying the better place to store this data is off chain and the link to the the off chain data through an nft is the best place to put it all um which, which is is sort of what this proposal contains.

A

That sounds interesting, I, don't know, but probably uh storing them, maybe on any L2 chain could also be an option, uh could be economical as well and hopefully that durability for storing it on and L2 could be higher than an off chain. Storage.

B

Yeah and that's a that's a good point too, um but it still kind of ends up plug in the L2 chain up a little bit. um It is it's. um It's a very good point, though it's um obviously I'm a big fan of the off James, so like don't clog, anyone's up and give the opportunity but yeah. This is the thing afforded by Altus. Right now is hey it's cheap and easy, and it's great.

A

Right and um uh probably there could be a standard for having integration of these L2 and mean that that would help store bigger data on the side chains, and we can have still have the transaction link on the main ship.

B

Yeah and that's a fair point too, is you could probably even store this data and it like this is the thing about um the token your RIS? It doesn't. Actually um it doesn't have an opinion on where it's stored, um so we could actually probably store a link to an L2 transaction, possibly in there and as long as it can sort of resolves to the metadata, um which sounds like an actually interesting proposals like what, if the token URI pointed to a L2 transaction like what?

B

What is the data resolved to I mean that's, probably an interesting idea in itself, um but that's a very, very good point. It's like hey. Maybe we can store it on the L2 and that resolves the database sort of situation.

A

But my next question is related to present the the system. The start. The proposal was documented in September 2022, but the discussion started early in July 2022 I mean this is generally the recommended process. When anyone wants to document any standard for ethereum blockchain, we recommend that create the discussion figure out if people are interested in that and then come up with a proposal. So that is the best thing that you have done. So. Thank you. So much for doing that. My question is um The. Proposal already received a lot of Attraction.

A

A lot of question. Answers are going on the discussion. Viewpoint The Proposal is still in track. When can we expect this in reveal and Part? B of this is how far it is from last call or maybe becoming a standard.

B

uh So I actually think it's ready for review and now um I was, for the most part, I had a lot of discussion on the um if magicians, farms and and then I was kind of trying to drum up some of community uh engagement, so I've been uh trying to get on Twitter I don't have a huge presence there, so it's been building that up as well trying to get some interest in it um and that was sort of like yeah September I launched CIP, and we did some back and forth and then I've had a couple months of me trying to drive my interest on Twitter for it, uh which we just had some good responses.

B

Again, it's I've still quite a small presence there. So it's as far as the like physical um proposal data. That's there at the moment, like I, have nothing to change. Really like it's ready to go change to review. I was I was just trying to give the community some more opportunity to discuss it, um particularly because the Jason schema is something I. Don't have a a strong opinion on um it's literally just like hey here's, my Common Sense idea of what the um receipt data should look like, but I guess um it's.

B

It's sort of the thing that a lot of people do have an opinion of, um especially because different jurisdictions in the world have different requirements.

B

um So I was trying to get a variety of people to say, like hey um over in over in the U.S, the there's the opportunity for multiple sales taxes um versus in Australia. We only have one sales tax that you're going to receive, so that wasn't originally built in I sort of knew that that was the case and was going to have to do that. So it's like those sort of different jurisdictions, I wanted comments from people, a big variety of people to do uh which I, which I've got a bit and I.

B

Think I've picked up a lot of um like a lot of the the different jurisdictions and how they do it. So I was throwing that net as far as I could and trying to drum up as much interest as I. Could. um However, as far as like um the actual proposal is right now, I'm, pretty ready to click, go I'm, changing it to review status, so I think I'm, probably doing that it like just got through Christmas and New Year's.

B

So it's probably um it was a bit there where I wasn't really looking at my computer either so I um I.

A

Think I'm probably gonna, do.

B

That in the next week or two and then yeah, if this, um this sort of call goes out at the same time, you're, probably watching it at the same time it's for review. So um that's probably what's going to be happening next.

A

That is good to know, and just for you to know earlier there wasn't this status called review, so people used to keep it in draft and then straight away, move it to last call now that we have review it's safer to be in the review side. So everybody, including EAP editors, knows that this is for review. It's a good thing.

A

That proposal itself got attention and we are getting a lot of questions answered going on in the chat, but moving to the right status is probably the best step to do and for last call uh there is a wait period of 14 days. So whenever the proposal is ready, you think that it is okay, fine, I'm good, with going into the panel making it a standard, you can move it to the last call.

A

It will be staying there for two weeks 14 days and then you need to make another pull request to move it to the funnel status as far as the different jurisdictions. So you mentioned um I think this is going to be a standard. Customization can be done on individuals level like wherever people want to implement this proposal. So it's good on it's good and it could be on them to do the customization on a high level. It is providing the Json schema, so that should be useful for people.

B

Yeah and that's a good point is um I think there's probably an element of different jurisdictions need like specialization anyway, so that they'll probably need sub subcategories of um the structure as well. So um it's good to know that our process I think probably what you've mentioned you've probably hit to that is um I've left it in Draft, when it should be a review like this is time for the community to be reviewing it um and that's what I've been trying to get them to do anyway.

B

So review is probably the right place for it to be right now, um there's no real changes. I need to to the structure anymore, so uh probably moving that ASAP.

A

Awesome, that's good to know in case of any issues, questions comments like uh if you want to talk to EAP editor. You are welcome to join the EAP editing office hour, a bi-weekly meeting that is organized by ethereum Caterers um generally. The agenda is available on ethereum cathered eip-ip GitHub repository, so you can propose your pull request over there and that would be taken care of.

B

Amazing awesome.

A

All right, um it's time to wrap up, is there anything else that you would like to share with the developers community.

B

uh No I I think I've um I've got my sort of everything I had written down uh into the call, so I'm very happy with what I've got there. I appreciate your time. I think this has been really productive.

A

Likewise, Sean Darcy, on behalf of ethereum Caterers I, would like to thank you for joining us on Peep and eat, and talking about EAB 5570 digital asset non-fungible tokens.
