A

Hello everyone,, a very warm welcome to the second file.

A

Coin: virtual community meetup., my name is emily and I'm a.

A

Member of the file coin- ecosystem team., we're so excited.

A

To have you here today we have a very wonderful lineup of speakers in store talking about some of the amazing projects.

A

That they are building on file coin.. Our presenters will be answering questions via our community slack channel,, which.

A

Can be found on the meetup comm page that you registered through.

A

In the what we are about, section. additionally,, if you.

A

Would like to stay up to date on the latest file, coin news and events,. Please subscribe to our newsletter as well as our filing.

A

Youtube channel, which are both linked in the meetup.com page.

A

Now, let's get started. first up, we have nick d'andrea, head of.

A

Engineering at truffle truffle is a software engineering tool.

A

For building smart contract based decentralized.

A

Applications. nick will be telling us about truffle preserve a new command for bridging the gap between your.

A

Decentralized applications front end and the entire world.

B

Hi, everyone., so I'm nick,, I lead engineering for truffle.

B

And I'm excited to show off a new feature that we're adding to.

B

Truffle today called truffle preserve, or truffle preserves,.

B

Because they're delicious. and the feature is still kind of.

B

Experimental, but we're really excited about it., so I figured.

B

We'd get it to you as soon as we can,, so you can start playing with it. so,. What truffle preserve is, is a command that.

B

Adds support for a workflow that hasn't really been in truffle before.. If you, members of the audience have used truffle.

B

Before you know that it handles things like compiling smart contracts,, it handles testing your smart contracts,. It has a.

B

Built in solidity debugger,, but there was never really a good.

B

Answer for how do you take your front end your dap front, end and.

B

Get that on to a decentralized network. and I've been a big fan.

B

Of ipfs for a long time and filecoin is now you know, with the.

B

Work that filecoin's been doing,, it's really becoming possible to put your dap front end on ipfs. and then, when.

B

Everyone stops seeding, your, your front end,. You can go to.

B

File coin and get it again and put it back on ipfs., and so that.

B

I think really completes that workflow., and so we built.

B

Truffle preserve to kind of showcase this workflow and let.

B

You take advantage of it., so we published this on a disk tag., so.

B

If you want to try this at home,, you'll have to do npm, install dash g truffle, app reserves., and you can also,. I put together an.

B

Example, box: you can once you have truffle app preserves.

B

Installed, you can run truffle, unbox, preserve, dash, example. and.

B

I'll show you what that looks like., but the features that we.

B

Include. to get started with this initial kind of.

B

Experimental releases we support preserving ipfs, preserving to.

B

File coin and I'm calling it a feature that this is pluggable.

B

Because I really hope that these aren't the only two.

B

Capabilities, right?, like even among just ipfs. and file coin,,.

B

Like, might think, oh,. I want to pin my content ipfs or oh,. I.

B

Want to interact with the ethereum name service, to give my.

B

Ipfs hash, a name., and so I'm really excited about. What's to.

B

Come there. and I hope that, you know,, the community comes up.

B

With use cases that I haven't, thought of. so to show this off,.

B

I have a demo prepared for you, all., and I just wanted to start.

B

By saying that, there's one prereq that I found really.

B

Useful, and that's power, gate. power gate provides this local.

B

Net mode, and it's really easy to set up you just follow these.

B

Instructions., and so I have that running, already. and that's kind.

B

Of what I'm going to be doing so I'll start and I'll just run.

B

B

We'll get it installed.

B

On box preserve in sample.

B

And this is pretty much an empty truffle project. there's some.

B

Directories that you'll see they're empty., but I have this.

B

App directory and that's what I'm calling my, my front, end.

B

And so that's what I'm going to be preserving today., so I can do.

B

That. well, first, let's learn about truffle reserve. truffle.

B

Has a built in help system, so it can be handy if you want to.

B

Learn about all the options., so right now the options we support are dash dash and by and I'll get into that in a bit. and then.

B

Dash dash ipfs and dash dash file coin., so you can see,. I can.

B

Use that I'll start with ipfs. I'm going to save my dap front.

B

End ipfs., and this just took the contents of that directory and.

B

It put them in the power gate, local network, that's running.,.

B

It's not talking to anything else, like no other ipfs nodes.

B

On the real ipfs network. but,, you know, it's pretty quick to.

B

Get started., but I wanted to show more than that. so here,.

B

I'll show you. inside the truffle config, I've set up an.

B

Environment and in fira graciously exposes their ipfs.

B

Endpoints to the world., and so I'm going to take advantage of that. and we'll do truffle preserve.

B

This full screen. and I'm going to specify ip fs and I'm going to specify that I.

B

Want to use the fira environment.

B

And the hashes are going to be the same., but now it's actually.

B

Been saved to another node on the network, one, that other.

B

People can access., and so let's see if that works.

B

Well, does I just deployed a decentralized application.

B

So let's try file coin and I have to apologize the demo gods.

B

Were not happy with me today., so I'm unable to actually preserve.

B

This app,, I just saved ipfs., so I have a separate directory that.

B

Is behaving and the file coin, if you're not familiar with the.

B

Fire file coin workflow,, if you want to initiate a storage deal,.

B

To save something to file when you first save it ipfs, so the.

B

File coin support what it does first, of course, is it. It saves.

B

Time. pfs captures the cd and then it uses that cd for the.

B

Storage deal. yeah, there we go., so what has just happened is we.

B

Uploaded the directory stuff to ipfs,, we captured the root cd.

B

And then we negotiated a storage deal to my local file coin.

B

Network to ensure that this data will be available for retrieval.

B

Later., so right now, that's mostly serving as a backup,.

B

Because it's not like the public internet can go and,. You know,.

B

Type in a url for a file called url because,, you know,, you have.

B

To pay retrieval deals in addition to storage deals,, but.

B

This data is backed up and then you can go and look up. The storage deal by cd on your own, like when you need it, or you.

B

Can do a retrieval deal for that content later.? The initial.

B

Plugins that I've that we've put together are well just truffle.

B

Preserve fs to actually read from disk. in the future,, maybe.

B

We would, you know,, maybe you want to load data from.

B

Elsewhere,, not just local files., and so we wanted to keep that.

B

Open for,, you know, other use cases.. Then we have the truffle.

B

Preserved ipfs plugin and the truffle preserve to file coin.

B

Plugin. but as I mentioned, we're really, you know, I,, I'm.

B

Particularly interested in the ipfs pinning dns workflow that a.

B

Lot of dap developers are using today. and so expect that to.

B

Come shortly. but these are all written as plugins,. So there's.

B

Nothing special about them, except the truffle at the beginning.. But if you wanted to make your own plugin,, you can.

B

Just add it to your truffle config or have other users add your plugin to their truffle config, and it should just work out of the box., so I have for now. If you have any questions,, I.

B

Guess reach out in the phil events channel in the powerpoint slack.. Thank you very much,. Ron.

A

Thanks, nick., that's very exciting,, like nick said,. If you.

A

Have any questions for him or the travel team,, then please.

A

Remember to pop them in the file point and then slack channel., so.

A

Next up, we have jonathan schwartz. jonathan is the co.

A

Founder of open work, labs, a product based studio based in.

A

Brooklyn that builds tools to improve the way that people.

A

Share, organize and archive their work. he's going to teach.

A

Us a bit about openwork labs is glyph, a web wallet that is.

A

Built on file coin.

A

go ahead,, jonathan.

C

Thank you, in addition to helping people share their work,.

C

One thing that I'm particularly interested in is like making it.

C

Really easy to get up the learning curve for web three.

C

Technologies. and so a lot of the products that we'd like to.

C

Build. ideally,, they feel like web 2.0,, like all this sort of.

C

Familiar user experiences, and under the hood are using some of.

C

These more technical things that are going on and today, one.

C

Thing that I thought would be cool, like,, it's also kind of hard for me for some of these meetups, because I don't always.

C

Know where everyone's at, technically. so an assumption.

C

Today is like,, I'm just gonna pretend like a lot of people.

C

Know very little and make it so that when you leave,, you know.

C

How to get started just playing around with file point through some of the tools that we've built.? We have this one brand.

C

Called glyph. and it's like, it's kind of confusing, because.

C

It's changed a little bit, but like glyph is this umbrella term.

C

That we're using for all the little tools that we're building for the file coin and ipfs ecosystem. and so today, I'll.

C

Show you two, here is the wallet now, obviously,. Like I said,. We.

C

Want to make things feel like web two.. There's a certain like when you when it comes to wallets that are sort of like.

C

Self custody,, meaning the user themselves, are in control of.

C

Their private information. it's kind of hard to not introduce.

C

Some new patterns along the way. so,, but that's okay.. I think I.

C

Can help explain or demystify some of these things as we go.

C

So I guess like, if you were just about to get started.

C

Entering the file coin, ecosystem, there's a lot of potential entry points. and I think it depends what you want.

C

To do, right? like that's sort of the starting point., but I.

C

Guess one one way to get involved is to start by making a.

C

File coin wallet, getting some file called some test net file.

C

Coin on that wallet, to then you can go and send it to friends.

C

And family, even though it's not worth anything yet. and then you.

C

Could play around with with this verification service as well, so that you can get better kind of like service from miners in the.

C

Network. and if that doesn't make sense now that's okay. I'll, explain: that. so, how to get a wallet.. Let's start here. this.

C

Is the glyph wallet, as you can see, there's a couple different.

C

Options for how to use this. so one,, this ledger device is a.

C

Hardware: wallet.: that's! If you're looking at the camera,.

C

That's this thing., so that's the safest, option., the other three.

C

Are insecure. and I'll explain why a little bit as well., but if.

C

You're just playing around with sort of testament file, coin, or.

C

You want to build an app, on file coin,, it's totally fine,. I.

C

Think to use these other options, I do all the time.. So let's.

C

Start with generating a new seed, phrase. and again,, here's the.

C

Warning., don't do this., I know., so I get so. Here's a seed.

C

Phrase,, which is, for I'm sure, a lot of you know,, but in case you.

C

Don't,, a seed phrase is a number of words.. These words are sort.

C

Of like pre, determined beforehand,, which ones are valid.

C

Or not, and then you kind of order them in different ways and.

C

Doing that you basically take this border of randomly.

C

Generated words. and you can derive sort of secret.

C

Information from those words that you use to make your.

C

Wallets. and so that's,, if that didn't make sense., I think.

C

That's okay, for now, it doesn't,. You don't necessarily need to know how this works in order to use it., but the.

C

Important thing to know is like,. These words are super, super.

C

Secret, like more important than your credit card number or the three digit code on the back., like I treat these for my actual.

C

Like crypto wallet as my social security number like no one.

C

Knows about them. and if I die, it's gonna be hard to find them.

C

So,, I guess for now,, I will copy these. and then we can go on to.

C

The next step, where we challenge you. but for now,, I'm going to.

C

Take a shortcut, and I'm just going to import that seed phrase.

C

Thompson number two., so I just pasted in the one I just copied.

C

From the first step. now, we're inside the wallet., so I'm.

C

Actually, on the current file, coin, test, net. and so just like,,.

C

Just like the demo gods are now on mc side,, like they weren't on.

A

My side today, either our, our block explorer,. The thing that.

C

We use to populate this transaction history wasn't working earlier today.. I don't think it's going to work. Now.

C

But that's okay., we can, we can make it work in bits and pieces,.

C

And I can explain: what's going on., so you'll notice a couple.

C

Things on the screen, here. one is that I have this account.. We.

C

Call this just our primary account,, you could call it like default, and it's this really long sort of string here and I.

C

Can show you I'll copy it, and where can I paste it so you'll.

C

See,, maybe I can paste it actually,, I can go in here and I.

C

Can paste that that string here.? So this is my full wallet.

C

Address. and again, it was generated from that really long.

C

Seed phrase of 24 words. and that seed phrase can also.

C

Generate many other addresses as well. and I can use all of.

C

These,, you can think of it as like. Your seed phrases like your.

C

Actual wallet, and then all of these individual accounts are.

C

Kind of like individual debit and credit cards almost., and so.

C

They all have their own balances. and the same seed.

C

Phrase will always produce the same number of accounts.. So if I.

C

Completely log out, and I log back in with the same seed, phrase, you'll, see the same things here, same order, same.

C

Bounces. and when I started working in crypto,, this took me.

C

Actually, a while to to understand how all this works.

C

So hopefully this is a little bit demystify for you., so I'm.

C

Going to stick with this first account and the first thing that.

C

We would probably want to do is get some flowers. and the final.

C

Point team has put together this fountain. um,. It's called this.

C

Lotus dev net faucet, where I can actually paste in my address and.

C

Send it funds. so now, you can imagine, like, I've just, I've.

C

Just gotten some final points sent to me over the network. and.

C

Now we just kind of need to wait for it to get processed. like imagine. You send a bank payment from one person to another,.

C

Like,, sometimes if it's venmo,, it's really quick. or if you're.

C

In europe,- and you don't know what venmo is, it's kind of just like a digital way to send cash from your bank., but sometimes.

C

Wire transfers will take days. for file coin.. This usually.

C

Takes like a couple minutes, and we'll see: hopefully, eventually,.

C

My balance will pop up. it'll say, oh, there we go. so now. We.

C

Know this.. This wallet now is 55 one,, which is a lot and again,.

C

It's not actually worth anything.. This is test. net file, one and just to show you sort of a different window into.

C

The network, this random looking string is actually like the.

C

Message id or a c id., and you could plug that into a block.

C

Explorer,, like file scan here., I just pasted the url at the top.

C

Here,, that's the c id from my message. and we can like go.

C

Ahead and inspect that. and just take a look at like,. What.

C

Actually is it?, so it was at this time, which looks right.

C

According to my clock., it was from some address to the address.

C

That is on my screen: here. jq ends in jq. and just some other.

C

Information that I think just for the sake of time,, I won't go too deep, into.. So now that I have five points,, I can actually.

C

Go ahead and send it to people., so let me switch to a different.

C

Address and copy it, switch back. again,. I don't think this.

C

Is going to work. yeah,, I'm sorry,, the demo gods are like.

C

Partially on my side,, but not with this transaction table., so.

C

I'm going to send that second account,, some five points,, maybe.

C

Just five. and let's watch that happen., so here, again,. This is.

C

Working because I don't have to go into the details now., but.

C

This is kind of like a different approach to building the.

C

Transaction table, while you're already in the wallet., so at least here we can look at the transaction. again,, like you'll.

C

See similar things that you saw on file, scan, you'll, see who it.

C

Came from, to this wallet., we'll see where it went to how much it.

C

Was and transfer fee, and then we can also look at it on on the.

C

Block explorer., that's the basic wallet like it's pretty,, it's pretty straightforward. and I guess, or I shouldn't say that if you're.

C

Brand new to this, it might still be really confusing., but.

C

At least as far as wallets go,, there's not that much going on.

C

Here., it's just a way to send the file coin that you already have when it comes to receiving file. Coin. basically,, as you.

C

Probably noticed, you can just take this address and send it to.

C

Anyone and then they can plug that into their send interface.

C

And then go ahead and click send. yeah, and then you should.

C

Get the file., so it looks like that transaction went through.

C

That's good.: we can look at that file, scan and just double check.

C

That it looks like we want it to and it does. It was five file coin.. It came back successfully., so the demo gods are not to meet.

C

Today. some some things that I learned while develop because.

C

Wallet because the first couple weeks, I just really spent on.

C

Trying to understand what are the, like big security threats, here. and and there's a lot of security threats that are that.

C

Don't have to do with web based wallet applications, like.

C

Physical attacks., like if someone approaches you on the.

C

Street and ask for your phone,, which has your private key,.

C

That's that's like getting hacked.. It's not all sort of that green and black terminal. Where you lose your information.

C

Someone's in your wi fi, router. and like,, it can happen in many.

C

Different ways., but I think there are some interesting things to note about why it's insecure to actually copy and.

C

Paste things into your browser and generate seed phrases in your browser., because I urge you,, if you're thinking about.

C

Really like storing file coin somewhere,, don't don't use these.

C

C

There's a there's a bunch of reasons why? But.

C

I think the web is not considered a secure, place.

C

There's a lot of things: that, like, for example, here,. I have.

C

A number of extensions.- I don't even have that many., but some people have,, like grammerly.. They have other things that are.

C

Allowed to actually, like, put javascript into your web pages.

C

And so some things that can go wrong are like a chrome.

C

Extension could peek into your browser and start looking at.

C

Your let's say,, what's on your clipboard?, I think linkedin.

C

Actually, just got sued for sort of surveillance of the.

C

Clipboard. and if you just copied your mnemonic, and then.

C

You paste it at somewhere,. Some chrome extension could steal.

C

That from you. and it's just as easy as that. and now,, because.

C

We know that a c phrases used to generate all of these wallet.

C

Accounts, they can easily steal your money. another one is that.

C

Some of these javascript, like these chrome extensions, can inject some javascript into your page that anytime, they see a.

C

File point looking address,, they can change it. and they could.

C

Just swap in their address., so when you click that receive button,, you're, actually like, sending your friend, the wrong.

C

Address. and you didn't even have any idea., and I guess that.

C

That can happen in a number of different ways., but I would, I.

C

Would urge you to only stick with these things for testing.

C

And development. and then, when it comes to actual use. there.

C

Are there are many more secure ways to go about doing this. in.

C

The interest of time, I wanted to get more into that,, but I.

C

Think I only have five or so minutes., so I want to talk quickly about file coin verification., and so this is a.

C

An app that we put together, that's still a work in progress.

C

it's,, it's it is working in parts, and you could you could.

B

Use it, but I think it's better to give you an appetite of why.

C

This is important. and then maybe in like a week or so you.

C

Could jump back on and get verified storage., so the fog.

C

Coin team wants to do a good job of incentivizing mining miners.

C

To store real data in the network., so essentially, like,.

C

This is a definitely a simplification., but if you, as a.

C

Human, have verified your file coin address,, so we could go.

C

Back,, hang on,. Let me go back to the wallet really quick and plug back in my seed phrase and get my address.. So this is my address.

C

So this is my address.. If I prove to the verification service that.

C

This is my address,, and all I have to do is link to my github.

C

Then paste in this address,, then that address will have eight.

C

Gigabytes worth of what's called verified date like a verified.

C

Data allowance. and so miners in the network, who are actually.

C

Responsible for, for storing the data,, they will be rewarded for.

C

Storing data that is considered, verified or has come from an.

C

Address that's verified with a data allowance., so I heard.

C

Myself say that and it sounds kind of confusing., so I'm just going to say that one more time,, if, if you successfully verify.

C

Your file coin, address, you'll you'll, get a data allowance of.

C

Eight gigabytes and any storage deal that you make on the.

C

Network with the with that address up to eight gigabytes.

C

Worth of deals that will be considered, verified and miners.

A

Will actually go out of their way to make better deals for you.

C

Remember, like, file- coin storage is an open.. It's like an.

C

Open market, right?, so you can find the best deals, and then go.

C

And ask to agree on a on a price at a time. and then from there,.

C

You've actually, you've actually, like stored your data with a miner., and so miners are incentivized to give better.

C

Terms,, whether that's cheaper storage, faster, like that there's.

C

Potentially many different reasons or ways that a miner.

C

Could incentivize you to go with them because they want your.

C

Verified data., but this is basically a way to get real data.

C

Into the network quickly during launch. and once it's,, I will.

C

Like, hopefully, next time we do this,, the demo will be a little.

C

Bit smoother and the test net will, like our nodes, will be able.

C

To to work through some of the hiccups., but for now, this is.

C

Sort of all I can show you, but you can read more about it. Here.

C

I love actually like in the file help., I'm sure, there's a lot of.

C

Questions., if you, if you are interested,, definitely go to.

C

This site and read it over because I like I want to do a.

C

Better job addressing those questions actually on the site anyway,, so it's really helpful. If you ask any questions.

A

Okay, so next we're joined by terry chad born from provo.

A

School. so proto school is an educational community that.

A

Teaches decentralized web protocols and tools through online tutorials and local events. today, terry will be.

A

Giving us a live demo of the latest tutorial featuring file.

A

D

So for those who haven't been introduced to proto school before,, it's exactly as emily and described, it's a community.

D

Project that tries to make d web easier to get started with so.

D

Trying to provide beginner friendly tutorials and events.

D

Based on those tutorials., so let's take a quick look at the tutorials first,, so pretty dot school is our website. and if.

D

You click on this tutorials tab,. You can see all of our content.

D

And one of the things we do in an effort to meet people's needs.

D

Is we have this option to quickly hide our javascript.

D

Coding challenges., if you're someone who is not a developer,.

D

And that content is not right for you,. You can hit this toggle.

D

Right here, you'll see that we have our different types of.

D

Content clearly labeled here for you., so now we're adding more.

D

And more of these multiple choice: quizzes. we have javascript coding challenges,, particularly on ipfs courses.,.

D

But one of the features we just introduced today is a course.

D

Filter., so you can now look at specifically the content. That's.

D

Related to ipfs or the content related to file coin,, which is.

D

Relevant for all of you. and at the moment, we don't have coding.

D

Challenges on the file coin., so all of this is going to be accessible, regardless of your level of coding, experience. and.

D

You'll see that, for each of these courses. is we've included.

D

Not only things that are directly on target for that project,, but also sort of underlying concepts that we find important. so for example, with file coin,, it's really important to understand what content addressing is.. So you could look.

D

At our decentralized data structures tutorial to learn about that, and then move into this one on verifying storage on file, coin. and now,, I need to undo everything you just heard.

D

About verification from jonathan,, because I'm talking about something completely different: here,, not about verified clients and sort of getting the checkmark next to.

D

Your name like you would in twitter. but instead, looking at.

D

The ways that you as a storage client know can be sure, can.

D

Verify that the miner that you're storing your data, with,.

D

Is actually storing it. so on the d web, one of the big.

D

Challenges that we face is we're working with peers, who we don't.

D

Know we're not storing our data with a company where we know.

D

Their reputation already. so there's this issue of trust and.

D

Concern. addressing helps with that., but in file coin,. We have.

D

Incentive mechanisms, and proofs and consensus mechanisms that.

D

Help us to do that., so this new tutorial that came out last week.

D

Is about those verification, methods and how, why you should.

A

Trust that your data is actually being stored by the miner. and.

D

What happens if their computer, fails, and they're no longer.

D

Storing your data. so, each of these lessons,, it has, you know,,.

D

An introduction to a new concept, and then a multiple.

D

Choice, quiz. and you'll get a little feedback on each of these.

D

If you get it wrong, the first time to kind of help guide you in the right, direction. and you'll, also notice throughout proto school, that you can go back to the table of contents.

D

For your lesson and see where you stand,, we can see that we've already finished lesson one, and walk through all of the lessons.

D

Prior to school, tutorials are meant to be consumed in order.

D

So it's not like a documentation site where you're going to have a great experience. jumping into a specific article,. This is.

D

Really ordered content. so always start on lesson one and go to school, get through to the end., but I just want to call out that we do have resources pages on on each of these.. So this is.

D

A good place to go and get either like,. What's the next thing you might want to learn?, or where can you go to dig a little bit deeper into the content here.? And if you do finish toriel on the pro school site,, we would love your feedback.. So we have quick little smiley face surveys. and.

D

Then all of our tutorials on pro school are also available to be.

D

Taught at events. so for example, tomorrow, ipfs africa is.

D

Hosting an event where their content for that event works.

D

With our decentralized data structures tutorial., so our events tab here will show you upcoming events.. There are also.

A

Past events, just you can see like the groups near you, learn.

D

More about them, you'll find links to the groups that host those events.

D

and if you want to learn how to host an event,, we have the host tab here for you., so feel free to reach out to me for more information about that. In fill, events today. and the other.

D

Thing I just want to call out for anyone who who has been playing around with frodo school, but wants to stay.

D

Updated, we do have a newsletter now., so we, we email, sparingly.

D

But if we launch a new tutorial, or a really important new.

D

Feature,, we would send you a note. and if you are interested in hosting events,, then I recommend checking this box right, here. and then we'll also send you any new materials that.

D

We put out for people who do want to lead events. so feel.

D

Free to use that I hope people enjoy exploring proto school.

D

and I'm super excited that we now have the outline content to.

D

Offer you., so I will drop a couple of links in the filaments.

D

Channel that you can use to get either to this course or to the file coin content. and if you've ever played around here- and you know, someone who say is interested in ipfs, but not coding,. This url is changing as you go., so you can always copy.

D

That url and send someone just the filtered list of things you think might they might be excited about.

A

Awesome. thanks, terry. I've heard rumors that proto school.

A

Team is working on some new awesome, vulcan content., so.

A

Definitely subscribe and you know, sign up for those.

A

Newsletters,, so you can be the first one to view those. and if.

A

You've got any questions,, please direct them to terry in the.

A

Events, room slack. and last,, but most certainly not least,. We.

A

Have been been around and co founder of small data industries, then founded small data industries out of a desire.

A

To bring the expertise and capabilities of the world's best.

A

Museums to broader artwork, art, world ecosystem., today, ben will.

A

Tell us about how he and his team are approaching digital.

A

Preservation, storage through the starling project.

E

Awesome. thanks so much, emily.. So for those of you who saw me.

E

Speaking, ready layer one,, this will be kind of like a little.

E

Update., and for those of you who haven't, and haven't.

E

Participated in the file coin developer little meetups,. This.

E

Will be all new. so welcome., so small data industries is a lab.

E

Based in brooklyn. and our mission is to safeguard the.

E

Permanence and integrity of the world's artistic record., and so.

E

We do this by working with cultural heritage, institutions,.

E

Artists, studios, nonprofits and art collections on everything,.

E

Consulting and services for art,, conservation,, digital.

E

Preservation, information systems. and we have been lucky.

E

Enough to work with institutions all over the world to do this work., so within our world of cultural heritage, institutions,.

E

There are pretty serious standards for digital.

E

Preservation. they actually come from the space data community,.

E

Which is pretty cool., but there are literal iso standards for.

E

This kind of stuff., so it's something that you know, in.

E

Cultural heritage people are thinking about and have been thinking about for decades, in terms of how to rigorously.

E

Establish whether or not you're doing a good job of stewarding.

E

Tissue. information. unfortunately,, despite this,.

E

Many of these institutions really struggled to meet the most rudimentary requirements., so this data is a little old at.

E

This point., we just did a new survey and we're in the process.

E

Of updating this., but two years ago, we did a survey of 75.

E

Different cultural institutions. and we found that a fair amount.

E

Of them had no geographic redundancy for their digital.

E

Storage for preservation., so meaning everything was stored in one physical location.. So if anything happened there, it would be gone. and in terms of so there's a term a term in.

E

Digital preservation that we use called fixity., you can think of.

E

It as authenticity., so it's the provable nature that a file.

E

Hasn't changed over the course of time. and digital preservation. People typically use a checksum like a sha, or mt.

E

Five., and so this and redundancy are the two most basic.

E

Requirements and we found that only a quarter of the respondents who took our survey actually are doing any kind of.

E

Fixity., so not only do a lot of people not have redundancy, a.

E

Lot of people really have no way of proving if their data,, you.

E

Know, hasn't been maliciously modified if it's been deleted. If.

E

It's been accidentally corrupted., and so we really.

E

Believe in the potential of file coin, to empower the world's.

E

Cultural heritage institutions to meet these really complex, requirements, through, you know,, collaborative and cooperative.

E

Communities. so we like to say his sterling is file coins.

E

Killer app.- and we say this because we're really, really,.

E

Really focused on the end users, who know nothing about.

E

Decentralized storage, we're really focused on the people who.

E

They just need to store digital information for a very long time.

E

And they need to be able to prove that it's authentic. and.

E

They will do this by any means necessary, but they're, probably pretty unfamiliar with all of the concepts from decentralized storage and don't necessarily want about them.

E

So starling has been a really collaborative project., and so we.

E

The initial development was done in partnership with a firm called post light. and our key stakeholders. were the usc shoah.

E

Foundation. of course, we've been deeply collaborative.

E

Protocol labs. shout out to moscow,. I saw us on the call.

E

And the latest developments in starling that we'll be looking.

E

At today, were developed by the team at digital mob., so.

E

Certainly consists of two components. there's a restful api, and a interactive command line interface.. So whether you.

E

Want to build like an electron app on top of the api, or if you.

E

Just want to kind of manually source, some stuff, or maybe do some cron jobs or something like that. The command line would be for you.. So what does it do? basically,? It does it for you.

E

Would want to do with file coin from the you know, highest.

E

Level,, storing files and folders, downloading files, kind.

E

Of monitoring your activity in terms of like what data is being.

E

Replicated to miners,, seeing what ceiling and whatnot,.

E

Listing your files,, seeing what you have stored in the network, and auditing the integrity of your files, checking in on those.

E

Really, really valuable proofs., so we abstract away from all the.

E

Deal negotiation, any kind of deal stage failures, it just.

E

Automatically retries finds finds better deals, file.

E

Chunking., so you can store files that are one terabyte. If you.

E

Want to, for instance, and we are doing also file level.

E

Encryption. because the stakeholders that we work with,.

E

You know, the can't have people accessing their data because a.

E

It might be illegal due to copyright, or it just might be,.

E

Something very, very valuable., and even if the the miner only.

E

Has a piece of it,: they only have a chunk of it. that still.

E

Wouldn't be acceptable to many stakeholders., so I just wanted.

E

To give you a quick little tour through the command line interface and show you what it looks, like., so the store command.

E

Can handle whatever you throw at it,? If you want to storage, individual files or folders,, you just tell it to store, and it.

E

Does. and before you would have gotten to this stage, when you.

E

Were installing and configuring your your installation,, you.

E

Would have told it whether or not you want to encrypt your files. and that's just a very basic, you know, public private.

E

Key encryption protected by a password., and you would have.

E

Also told it how many redundant copies you want to store. So many.

E

People, I'm sure, will be storing only one copy because they.

E

Consider storing and file coin, to kind of be analogous to maybe.

E

Storing in glacier. you know, it's kind of like a disaster copy backup., but some people might be more heavily reliant on.

E

It. and they might want to have redundancy within the network.

E

So you can store as many redundant copies of these files.

E

As you want, as just a matter of configuration., so downloading.

E

Similarly is incredibly straightforward.: all you need is.

E

The cd and the miner id,, so you can download from a specific.

E

Given miner.- and this is a background process because it.

E

Does take some time., so this brings us to the monitors. so.

E

Pretty typical heads up display for command line tools., so it's.

E

Kind of like h top in a way.- and this gives you some information about your wallet balance. and you know how many files you have.

E

Storage network,, how many miners you're connected to, and then.

E

All of your active jobs in the queue., so these are files that.

E

Can be either sinking or sealing., but everything that is.

E

Actively being worked on by your instance. and to list your.

E

Vitals, it's just a single line command, and it spits out a csv.

E

And actually, this mock up or this isn't a mock up of the.

E

Screenshot., this screenshot actually isn't up to date., and now it looks more like this,, which is the verify command.. So.

E

As you can see, there's a little preview of the content of the.

E

Csv., so the verify command is exactly what it sounds. Like.

E

Basically., all it does is it says, takes a given cd, and it.

E

Goes to that miner and it makes sure that they haven't been slashed.. So basically, that is just to check that the proofs.

E

Have been proven recently., so that's how you know that your.

E

Content, not only exists,, but it has existed on that particular.

E

Miners storage device over a particular period of time.

E

So, what's next? we are doing a lot of community and cohort.

E

Building. we're putting this in the hands of archivists and librarians and conservators,, and you know it. Professionals in the.

E

Museum and cultural heritage sector. our next stage,. We.

E

Really want to build a graphical user interface., a lot of our key.

E

Users who we're targeting, don't really use command line, tools.

E

So now that we have the api, that should be pretty easy to build.

E

On top of that. that.- and we are continuing,, of course, do really.

E

Extensive ux research because,, you know, with with this project,, it's not even so much about the technology.. It's it's.

E

More again about how we- and I think this is similar in some.

E

Ways to what jonathan was saying: about, you know,, taking these d.

E

Web technologies and these web three technologies and making.

E

Them understandable to people who are used to web two,. You.

E

Know, in some ways,, I think, with file coin and just decentralized.

E

Technologies. in general, we're in the really early stages, where.

E

When you look back to the first, you know, computer interfaces.

E

That were point and click, you know, from xerox, parc or from.

E

Apple with macintosh, you know,, skeuomorphic design was a.

E

Necessary evil, we needed metaphors, like the trash can,.

E

For instance, or folders, and less and less, you know, or more.

E

And more, we've moved away from those kinds of metaphors., so.

E

We're in a similar place right now with these kinds of.

E

Technologies, where the I think, a lot of the hard work lies.

E

Within., how do you build trust with the user?? How do you.

E

Communicate these like really layered complex issues to them.

E

In a way, that's user friendly, easy to understand and not.

E

Overly complex., so if you want to look into this further,.

E

Here's the website for starling and the two github repos for the.

E

Seelye and the api. and yeah,, if you have any questions,, feel.

E

Free to drop a line in the slack channel that was created for.

E

A

I would like to say a huge thank you to all of our incredible.

A

Presenters for taking the time to share their expertise and.

A

Their projects with us, and for showing us what an incredible.

A

Ecosystem that we're building on top of file coin., like we said.

A

Multiple times, if you have any questions or would like to present out a future meetup and join me, and our speakers over in.

A

The file coin events channel on the community slack. also, if.

A

You'd like to stay up to date on the latest news and events,, you.

A

Can subscribe to our newsletter and the following youtube channel,, which are both linked in the meetup page,. Thank you.

A

Again for joining us- and I look forward to seeing you all again on august 11 for our next virtual meetup., bye, everyone.
