SF Scala: Dmitry Meshkov interview

hello everybody I'm Alexi crabber of the hello everybody I'm Alexi crabber of the organizer of SF Scala and also the new organizer of SF Scala and also the new metal called SF in tech and blockchain metal called SF in tech and blockchain developers and here we are their second developers and here we are their second SF in tech on location of marquita which SF in tech on location of marquita which is a payment company out of Auckland is a payment company out of Auckland it's a beautiful space as you'll see and it's a beautiful space as you'll see and here with us we have mid ramesh cove who here with us we have mid ramesh cove who is co-founder of argo platform a new is co-founder of argo platform a new platform for cryptocurrencies and also platform for cryptocurrencies and also the developer of score X location the developer of score X location implementation written scholar implementation written scholar welcome to misery yeah hi everybody so welcome to misery yeah hi everybody so the middle you just give a talk at Cesc the middle you just give a talk at Cesc conference in Berkley can you tell us conference in Berkley can you tell us what brings you to Berkley and what did what brings you to Berkley and what did you describe in your talk there yeah you describe in your talk there yeah yeah so CA C is a conference about crypt yeah so CA C is a conference about crypt economics it's a crypt Economic Security economics it's a crypt Economic Security Conference and well mainly I'm here Conference and well mainly I'm here because a lot of interesting people are because a lot of interesting people are also here as I think the main idea of also here as I think the main idea of all of this conference to make some all of this conference to make some networking and to collaborate to discuss networking and to collaborate to discuss something as far as I know it's the something as far as I know it's the first conference about economics in first conference about economics in cryptocurrencies in a topic of security cryptocurrencies in a topic of security so it's not just you know general so it's not just you know general economic speech it's more scientific economic speech it's more scientific [Music] [Music] conference and my talk there was about conference and my talk there was about our new economic model we are going to our new economic model we are going to implement it in our NGO it's still in implement it in our NGO it's still in progress so it's not a final version but progress so it's not a final version but here mine I may start a bit at at all here mine I may start a bit at at all that tell you a bit about our our NGO that tell you a bit about our our NGO platform maybe yeah so you know we we platform maybe yeah so you know we we have a score ox framework we I mean have a score ox framework we I mean me and Alex Jeremiah who created this me and Alex Jeremiah who created this framework its main idea was to implement framework its main idea was to implement some interesting features it's a model some interesting features it's a model of framework so you can implement just of framework so you can implement just one feature and have all other features one feature and have all other features for free and we cooperate it with a vhk for free and we cooperate it with a vhk company that is a research company so we company that is a research company so we have implemented quite a lot of have implemented quite a lot of prototypes for different scientific prototypes for different scientific ideas found some bottleneck there and ideas found some bottleneck there and now we decided that we have quite a lot now we decided that we have quite a lot of interesting idea that due to not to of interesting idea that due to not to be implemented in a new blockchain be implemented in a new blockchain so we are going to implement a lot of so we are going to implement a lot of different ideas that should complement different ideas that should complement each other and one part of this Erika each other and one part of this Erika platform is a economy model so for now platform is a economy model so for now it's not well discussed topic actually it's not well discussed topic actually so most of cryptocurrencies just copy so most of cryptocurrencies just copy Bitcoin stuff without any research and Bitcoin stuff without any research and update and our idea is to make every update and our idea is to make every aspect of blockchain at least a bit aspect of blockchain at least a bit better at least we should make some better at least we should make some research and choose the best parameters research and choose the best parameters here mm-hmm here mm-hmm interesting and so and also you in interesting and so and also you in addition to having this kind of advanced addition to having this kind of advanced Cal implementation you also develop this Cal implementation you also develop this efficient memory data structures right efficient memory data structures right that let you keep the state of the that let you keep the state of the yeah so you talk about our yeah so you talk about our authenticated data structure right it's authenticated data structure right it's not actually even so efficient its idea not actually even so efficient its idea is a bit different it's authenticated so is a bit different it's authenticated so you can put any data to this data you can put any data to this data structure and you can provide the proof structure and you can provide the proof for some element in this data structure for some element in this data structure that it exists in a proof but it was that it exists in a proof but it was well known before us but in addition we well known before us but in addition we can provide the proof of modification so can provide the proof of modification so we have some value see now a data we have some value see now a data structure and you can provide the proof structure and you can provide the proof you changed this value to a new value you changed this value to a new value and you changed nothing miles so it's a and you changed nothing miles so it's a symmetric design there is a proven and symmetric design there is a proven and there is a verifier and proved accretes there is a verifier and proved accretes proofs that he updates some well using proofs that he updates some well using his data structure and the only thing his data structure and the only thing where if I should keep in his local where if I should keep in his local storage is just 32 bytes of hash hash of storage is just 32 bytes of hash hash of this data structure he can verify this data structure he can verify everything without any trust to anybody everything without any trust to anybody and that's extremely important for and that's extremely important for untrusted distributed blockchains untrusted distributed blockchains systems like a Bitcoin because this list systems like a Bitcoin because this list data structure it's possible to provide data structure it's possible to provide the proof for example that transaction the proof for example that transaction is correct that the sender actually have is correct that the sender actually have this money so the one of our ideas of this money so the one of our ideas of occupied from is to create a symmetric occupied from is to create a symmetric design to provide proofs for everything design to provide proofs for everything and us verify can download just a small and us verify can download just a small small piece of data to your mobile phone small piece of data to your mobile phone like 100 kilobytes and you can verify like 100 kilobytes and you can verify everything without any trust to to everything without any trust to to anyone interesting interesting and you anyone interesting interesting and you mentioned I think you mentioned another mentioned I think you mentioned another number like one hundred eighty two number like one hundred eighty two gigabytes which is the total Qi bytes gigabytes which is the total Qi bytes you're right kilobytes okay your voice you're right kilobytes okay your voice is different okay so you don't need you is different okay so you don't need you basically don't need the whole basically don't need the whole blockchain that's yeah yeah only needs blockchain that's yeah yeah only needs from the whole block chain that is a few from the whole block chain that is a few hundred kilobytes you all right sorry so hundred kilobytes you all right sorry so all you need is just this small piece all you need is just this small piece one hundred kilobytes it's it's very one hundred kilobytes it's it's very small actually you can download it on small actually you can download it on your mobile phone it's less than any your mobile phone it's less than any code and you can start work with this code and you can start work with this blockchain without any trust that is blockchain without any trust that is absolutely new feature now because in absolutely new feature now because in existing block chains it's impossible to existing block chains it's impossible to do such as hey you should download quite do such as hey you should download quite a lot of data mmm to start a lot of data mmm to start transaction creation for example in transaction creation for example in Bitcoin or he theorem and actually this Bitcoin or he theorem and actually this leads to wallet centralization a lot of leads to wallet centralization a lot of users don't like to download this big users don't like to download this big data set to the devices they prefer to data set to the devices they prefer to use web wallets they they think that use web wallets they they think that it's okay to trust this web wallet the it's okay to trust this web wallet the developers but sometimes this leads to developers but sometimes this leads to big steals we have an example from a big steals we have an example from a theorem classic when the most popular theorem classic when the most popular web wallet was compromised and the web wallet was compromised and the attackers stilled a lot of private keys attackers stilled a lot of private keys a lot of money and actually he can steal a lot of money and actually he can steal money and show you as if you still have money and show you as if you still have this money on your balance so you open this money on your balance so you open the balance you see 50 theorem on your the balance you see 50 theorem on your balance but actually you don't have balance but actually you don't have right because it's just a web interface right because it's just a web interface that shows you something but you can that shows you something but you can check that it's also correct information check that it's also correct information interesting this is great so so so I'm interesting this is great so so so I'm curious right like so you guys published curious right like so you guys published the research paper of this and so the research paper of this and so anybody can take an implement so well I anybody can take an implement so well I can curse folks at the conference can curse folks at the conference percent like they're gonna use the this percent like they're gonna use the this data structures right so so I mean how data structures right so so I mean how does this space work right first of all does this space work right first of all the stuff that was not the block chains the stuff that was not the block chains right so we should want to compete with right so we should want to compete with and you publish your key results in open and you publish your key results in open how do you think you're gonna compete how do you think you're gonna compete what is your competitive advantage well what is your competitive advantage well first of all I should note maybe my and first of all I should note maybe my and not only my the whole idea about this not only my the whole idea about this area is that everything should be open area is that everything should be open to open source no research should be to open source no research should be open that's as far as I can see it the open that's as far as I can see it the only way in decentralized system because only way in decentralized system because it's a nonsense cryptocurrency has a it's a nonsense cryptocurrency has a closed codes because there may be some closed codes because there may be some backdoors and so on in each total backdoors and so on in each total protocol should be known some papers protocol should be known some papers should be known it's much better to have should be known it's much better to have them published on some pure them published on some pure buuuut conference like thermos for buuuut conference like thermos for example if published these have a paper example if published these have a paper about authenticated data structure about authenticated data structure financial cryptography conference we financial cryptography conference we have some feedback from interviewer and have some feedback from interviewer and it's very important for security reasons it's very important for security reasons so how the people should check that your so how the people should check that your ID is correct right there are now holes ID is correct right there are now holes here there are no problems with that and another you mentioned other guys that another you mentioned other guys that are going to implement the same stuff are going to implement the same stuff actually I like it absolutely like this actually I like it absolutely like this I mainly now blockchain industry is like I mainly now blockchain industry is like not a competition between different not a competition between different block chains I think but it's mock block chains I think but it's mock competition between block chains as as a competition between block chains as as a whole the community be to classical whole the community be to classical banks to fiat money and so on so I don't banks to fiat money and so on so I don't feel very big you know convention yeah feel very big you know convention yeah it's not a problem to have the same it's not a problem to have the same features and different block chains work features and different block chains work change collaborate and that's also what change collaborate and that's also what I like in this area because different I like in this area because different team collaborate share their experience team collaborate share their experience share ideas it's very open space to share ideas it's very open space to discuss them ideas and so on cool so you discuss them ideas and so on cool so you were a physicist were a physicist yeah so can you tell us how do we get yeah so can you tell us how do we get from physics to walk chain well actually from physics to walk chain well actually it took me few steps not just one so it took me few steps not just one so yeah I graduated from Moscow State yeah I graduated from Moscow State University from physical departments in University from physical departments in it and then I become to be a PhD student it and then I become to be a PhD student and Moscow Institute of chemical physics and Moscow Institute of chemical physics and I completed my PhD there but mainly and I completed my PhD there but mainly I was my scientific area was a computer I was my scientific area was a computer simulation so I simulation so I wrote programs I made some simulations wrote programs I made some simulations of chemical processes of chemical processes well my specialization was in a well my specialization was in a macromolecule astronomers all this stuff macromolecule astronomers all this stuff is actually quite interesting because is actually quite interesting because for example bro blockchain growth is for example bro blockchain growth is very similar to polymer growth mm-hmm so very similar to polymer growth mm-hmm so when you create a polymer is almost the when you create a polymer is almost the same as when you create block chains same as when you create block chains mm-hmm but it's not a topic here so I mm-hmm but it's not a topic here so I was a developer I was a student a PhD was a developer I was a student a PhD student and then I worked in a few just student and then I worked in a few just IT companies as a record developer and IT companies as a record developer and when I you know left my last regular job when I you know left my last regular job maybe from my previous life actually it maybe from my previous life actually it was quite boring for me all this I never was quite boring for me all this I never stayed in one place for more than a year and I decided to make some stop and to and I decided to make some stop and to research what I interesting topics away research what I interesting topics away in an area and then I decided to study in an area and then I decided to study blockchain said it was an interesting blockchain said it was an interesting topic for me but it was someone on topic for me but it was someone on background and I know I know that there background and I know I know that there is Bitcoin is Bitcoin it is something interesting but I have it is something interesting but I have no time to study how does it work right no time to study how does it work right when I get some time I decided to when I get some time I decided to research this to understand how does it research this to understand how does it work and that's actually how I found work and that's actually how I found Scottish project and my current Kovach Scottish project and my current Kovach and co-founder of ergo plate from and co-founder of ergo plate from Alexander to promote and so I found good Alexander to promote and so I found good source cover frameworks where you can source cover frameworks where you can play and you know prototypes and play and you know prototypes and blockchain so you can easily play with blockchain so you can easily play with scour and to study blockchain on example scour and to study blockchain on example so it was quite easy for me to maybe so it was quite easy for me to maybe read some papers while read some papers while original Bitcoin paper is quite easy original Bitcoin paper is quite easy it's quite good written actually read it it's quite good written actually read it if you haven't done this yet but an if you haven't done this yet but an example it's much much more interesting example it's much much more interesting and much better and yeah now I'm turned and much better and yeah now I'm turned a half years from that point and I'm a half years from that point and I'm still interested in this area and it's still interested in this area and it's still cool and I still like it yeah it's still cool and I still like it yeah it's super exciting and so can you tell us I super exciting and so can you tell us I mean I come from the same background but mean I come from the same background but you know a lot of folks maybe I don't you know a lot of folks maybe I don't know why is it good like you know if you know why is it good like you know if you basically go to University in Russia and basically go to University in Russia and study physics why well-prepared for study physics why well-prepared for Bitcoin space what are the skills they Bitcoin space what are the skills they teach you that make it easier for you to teach you that make it easier for you to do this kind of stuff well it's not so do this kind of stuff well it's not so easy question actually but yeah you know easy question actually but yeah you know even on my first year of my education in even on my first year of my education in Moscow State University there was a Moscow State University there was a point from our from staff of universe point from our from staff of universe that there are like four hundred people that there are like four hundred people on first year actually on first year actually well now country do not need four well now country do not need four hundred physicists a year but their hundred physicists a year but their education model change they did not education model change they did not prepare four hundred physicists a year prepare four hundred physicists a year they prepare for four hundred educated they prepare for four hundred educated people a year okay so you should be able people a year okay so you should be able to learn anything that's maybe the main to learn anything that's maybe the main you know skill you get from Moscow State you know skill you get from Moscow State University in the physical Department so University in the physical Department so you are ready to learn anything you can you are ready to learn anything you can read papers you can understand how it read papers you can understand how it work without any any help I think yeah work without any any help I think yeah that was the main the main point why it that was the main the main point why it was quite easy to follow blockchain was quite easy to follow blockchain stuff and to start working in the stuff and to start working in the science they actually so I have some science they actually so I have some papers in blockchain area papers in blockchain area look not not just a developer and my look not not just a developer and my researcher also probably some math right researcher also probably some math right yeah yeah sure you need the different yeah yeah sure you need the different stuff and the math is quite important stuff and the math is quite important and actually physics is also quite and actually physics is also quite important at provide you you know some important at provide you you know some high-level overview of some intuition high-level overview of some intuition how this should barking should work and how this should barking should work and Methodism or strict no I remember this Methodism or strict no I remember this you know from you know also from physics you know from you know also from physics and math right I came in I forgot like and math right I came in I forgot like half of this or more but you know don't half of this or more but you know don't surprise me when people who got purely surprise me when people who got purely Commerce's education they print Commerce's education they print floating-point numbers with 18 floating-point numbers with 18 significant digits I'm like you know you significant digits I'm like you know you could round it to three right there could round it to three right there you've got all of the three digits and you've got all of the three digits and almost nobody does this Yeah right so almost nobody does this Yeah right so I'm like you know we don't really need I'm like you know we don't really need this because it you know it like just this because it you know it like just takes place on the screen right but a takes place on the screen right but a lot of people do that and I think that's lot of people do that and I think that's a sign right physics can teach you a lot a sign right physics can teach you a lot visual stuff right so how did you get it visual stuff right so how did you get it to scholar ye scholar actually it's also to scholar ye scholar actually it's also quite an interesting question and it's quite an interesting question and it's not so easy but before Scour I tried not so easy but before Scour I tried quite a lot of languages actually mine quite a lot of languages actually mine main language was PHP and actually well main language was PHP and actually well it's possible to write good problem it's possible to write good problem programs on PHP I understood this and my programs on PHP I understood this and my one of my jobs well it's possible one of my jobs well it's possible actually it's but well it's easy to actually it's but well it's easy to write some small script on peach pits write some small script on peach pits much it's done for this stuff it's for much it's done for this stuff it's for personal home pages right yeah and it's personal home pages right yeah and it's good for for this stuff but when you good for for this stuff but when you create some big yeah so but when you create some big yeah so but when you create some big website API application create some big website API application and so on it became much much more much difficult to use BB and once you know I was on a conference in once you know I was on a conference in Russia DEFCON conference it's about like Russia DEFCON conference it's about like web development and when I was on this web development and when I was on this conference I understood that I know conference I understood that I know everything they these people from stage everything they these people from stage talking about and I'm not just now which talking about and I'm not just now which I usually it's and so on if I feel that I usually it's and so on if I feel that I'm like close to my limits in this area I'm like close to my limits in this area and now accidentally I found a very good and now accidentally I found a very good class on Coursera from our senators key class on Coursera from our senators key okay everyone now this course yeah I okay everyone now this course yeah I remember the first day I found it remember the first day I found it usually I don't like courses on Coursera usually I don't like courses on Coursera it's very hard to me to follow all the it's very hard to me to follow all the steps and I decided to start to learn it steps and I decided to start to learn it a bit before course that to have some a bit before course that to have some you know free space if I will be busy you know free space if I will be busy and and so on and and so on and I started to watch election from a and I started to watch election from a previous course and I watched all of previous course and I watched all of them in two days so all the crucial two them in two days so all the crucial two days I was very excited days I was very excited I absolutely liked it it was impossible I absolutely liked it it was impossible to touch me from computer when I walked to touch me from computer when I walked my when I watched these videos yeah I my when I watched these videos yeah I absolutely liked it then I perform two absolutely liked it then I perform two exercises and it's where is the best exercises and it's where is the best online course I've ever seen and I online course I've ever seen and I laughed scholars as a programming laughed scholars as a programming language and I changed my job to start language and I changed my job to start ask our developer yeah and after that I ask our developer yeah and after that I left from this job at scale developer left from this job at scale developer and become developed from in a and become developed from in a blockchain area that's really really blockchain area that's really really cool so I think we're gonna be you know cool so I think we're gonna be you know about the robot so I a location in about the robot so I a location in Alaska like who you you'll give a talk Alaska like who you you'll give a talk about score X and learn more about it about score X and learn more about it but what is kind of the key reason why but what is kind of the key reason why should people do blockchain Scala why is should people do blockchain Scala why is in score X like why is it a good in score X like why is it a good or started off like you know have or started off like you know have another setup toppled speaking later another setup toppled speaking later today and it took you know score x2 is today and it took you know score x2 is the foundation you know and like you the foundation you know and like you know he just learned about the dress know he just learned about the dress like I wrote people who are rarely like I wrote people who are rarely commented but why should more people commented but why should more people choose blockchain implementation in choose blockchain implementation in Scala yeah so there are two different Scala yeah so there are two different questions first is about kawaii you know questions first is about kawaii you know it's never when it's so very very hard it's never when it's so very very hard to fig fix any bugs so if you have a to fig fix any bugs so if you have a distributed system it's almost distributed system it's almost impossible to make release in a short impossible to make release in a short period if you have a bug you you have a period if you have a bug you you have a problems right if it will be exploited problems right if it will be exploited so you might fix your own node but there so you might fix your own node but there are other notes on other area and you are other notes on other area and you need the majority of nodes to be updated need the majority of nodes to be updated you okay you can connect them but anyway you okay you can connect them but anyway you have mineral-rich of nodes and you you have mineral-rich of nodes and you do not want to have a chain split do not want to have a chain split because if you make any changes to codes because if you make any changes to codes it may lead to change split if you have it may lead to change split if you have a bug this my links this may lead to a a bug this my links this may lead to a situation when part of your part of this situation when part of your part of this nodes and cryptocurrency follow one nodes and cryptocurrency follow one chain and they accept this transaction chain and they accept this transaction and another part did not accept these and another part did not accept these transactions they burn each other and transactions they burn each other and you have actually two different chains you have actually two different chains and so in in blockchain area securities and so in in blockchain area securities the the first topic absolutely the first the the first topic absolutely the first topic and you should write as accurate topic and you should write as accurate code as possible well Scala is quite a code as possible well Scala is quite a good choice for for this reasons good choice for for this reasons it's at least and I'll have static types it's at least and I'll have static types is not good types it have some is not good types it have some functional features at least the a you functional features at least the a you may write it in a different style so may write it in a different style so from my point of view it's for example from my point of view it's for example much better than C and C bar plus that much better than C and C bar plus that is still very popular in is still very popular in cryptocurrencies area mainly because cryptocurrencies area mainly because bitcoin is written in C language those bitcoin is written in C language those mines yeah yeah it's very difficult to mines yeah yeah it's very difficult to follow this course it's not even a C++ follow this course it's not even a C++ just to see some assembler and it's just to see some assembler and it's actually but yeah it's very if it was actually but yeah it's very if it was difficult to follow this secrets in difficult to follow this secrets in Bitcoin and it's quite you know Bitcoin and it's quite you know well-known property the more code of well-known property the more code of lines you have more box you have yes lines you have more box you have yes it's it's not a strict property but it's it's not a strict property but actually it works and so my point here actually it works and so my point here is that it's much better to spend more is that it's much better to spend more time for development so maybe even but time for development so maybe even but but but make more stable product with Oh but but make more stable product with Oh as possible box yeah that's like a few as possible box yeah that's like a few lines of code right let's go I think the lines of code right let's go I think the toppled mentioned is in the block you toppled mentioned is in the block you guys have 4,000 lines yeah but well you guys have 4,000 lines yeah but well you know it's not a property fall for all of know it's not a property fall for all of block chains it's possible to to write block chains it's possible to to write different implementations yes yeah but different implementations yes yeah but score rocks yeah it's very very small score rocks yeah it's very very small and our idea is to keep everything and our idea is to keep everything simple to be able to overview all the simple to be able to overview all the codes in your mind to keep it all and codes in your mind to keep it all and you mind like to understand the main you mind like to understand the main patterns architecture and so on patterns architecture and so on so yeah now we come to the second so yeah now we come to the second questions about quarks why why should questions about quarks why why should they actually use curves so skirts was they actually use curves so skirts was created for prototyping actually it's created for prototyping actually it's its main idea when it was created was to its main idea when it was created was to allow people to prototype some parts of allow people to prototype some parts of blockchain and we worked with large gain blockchain and we worked with large gain we implemented quite a lot of scientific we implemented quite a lot of scientific papers found problems with them because papers found problems with them because unfortunately it's quite a common unfortunately it's quite a common situation there is a gap between you situation there is a gap between you know know research and between to your theory and research and between to your theory and practice so we have academic researchers practice so we have academic researchers that may produce very good papers that may produce very good papers provably secure and so on but practice provably secure and so on but practice you can find that then impractical at you can find that then impractical at all its it's impossible to implement it all its it's impossible to implement it in the current step there is some in the current step there is some assumption that network is synchronous assumption that network is synchronous and you can spend the same tiny amount and you can spend the same tiny amount of data through your network but it's of data through your network but it's not true actually on the other hand the not true actually on the other hand the the ROC quite a lot of implementations the ROC quite a lot of implementations in cryptocurrencies also quite ad hoc in cryptocurrencies also quite ad hoc without any base knowledge behind them without any base knowledge behind them and you know cryptography and in and you know cryptography and in cryptocurrencies it doesn't work when cryptocurrencies it doesn't work when you create something and you tell I you create something and you tell I don't see any attacks to it and that's don't see any attacks to it and that's why it's secure if you don't see any why it's secure if you don't see any attacks to eat after some time someone attacks to eat after some time someone might found them right so the approach might found them right so the approach people from cryptography use is to people from cryptography use is to provide the proof of security that any provide the proof of security that any kind of attack that are possible in some kind of attack that are possible in some assumptions for sure it's very important assumptions for sure it's very important to follow these assumptions and to follow these assumptions and understand what what are they but like understand what what are they but like in Bitcoin there is proof in some in Bitcoin there is proof in some assumptions here that if less than 50% assumptions here that if less than 50% of nodes are controlled by the adversary of nodes are controlled by the adversary they may do anything they they want they may do anything they they want absolutely anything they can't absolutely anything they can't compromise the systems right it will be compromise the systems right it will be secure and it's strong mathematical secure and it's strong mathematical proof that of security so my maybe proof that of security so my maybe advice for you if you are going to advice for you if you are going to implement any cryptocurrency don't do it implement any cryptocurrency don't do it just it that's I should mention here just it that's I should mention here might be another good cool might be another good cool some Coursera from den Banach about some Coursera from den Banach about cryptography mm-hmm it's also very very cryptography mm-hmm it's also very very good course and it's mine you know ideas good course and it's mine you know ideas don't do any crypto do not invent don't do any crypto do not invent anything right and the same you should anything right and the same you should the same approach you should implement the same approach you should implement in cryptocurrencies there are a lot of in cryptocurrencies there are a lot of implementations and usually you don't implementations and usually you don't need your own blockchain need your own blockchain for your features it's possible too for your features it's possible too aren't you aren't you Owen talking on different platforms it's Owen talking on different platforms it's possible to use any blockchain as a data possible to use any blockchain as a data base and so on base and so on so in most of cases you do not need your so in most of cases you do not need your own blockchain you don't do not need to own blockchain you don't do not need to implement it by your own just use some implement it by your own just use some existing blockchain but yeah I research existing blockchain but yeah I research them out to score access so it's simple them out to score access so it's simple and it was his idea was to prototype and it was his idea was to prototype some to prototype some scientific ideas some to prototype some scientific ideas and done quite a lot of them and now and done quite a lot of them and now it's not just prototyping framework it's not just prototyping framework because there are existing production because there are existing production implementation of nodes based on score implementation of nodes based on score ox first one I should not he is waves ox first one I should not he is waves platform it's created by our good platform it's created by our good friends actually that uses quarks of friends actually that uses quarks of basics and now it's one of the most basics and now it's one of the most popular cryptocurrencies in Russia and popular cryptocurrencies in Russia and the second production blockchain the second production blockchain implementation I should mention here is implementation I should mention here is a mightiest client for film classic it's a mightiest client for film classic it's also based on some score ox ID it's it also based on some score ox ID it's it do not forc it's not a fork of score ox do not forc it's not a fork of score ox and it do not use it directly the our and it do not use it directly the our code is a library but it's inspired by code is a library but it's inspired by score ax it took quite a lot of parts score ax it took quite a lot of parts from it and it's follows where they main from it and it's follows where they main architecture here and yeah so now we are architecture here and yeah so now we are going to implement our own products going to implement our own products blockchain elbow and based on scourge so blockchain elbow and based on scourge so it's now not just a framework for it's now not just a framework for prototyping but framework for production prototyping but framework for production block chains we hope at least what's block chains we hope at least what's super exciting so thank you much for super exciting so thank you much for sharing this and we're looking forward sharing this and we're looking forward to your mettle yeah thank you
