  • Lisk Swift - Swift SDK with Local Signing, targeting Lisk 1.0.0




    One of the biggest draws to
    Lisk is its simple API that is instantly familiar to anyone making
    modern day web, iOS and Android applications using http clients. With
    this instant familiarity comes the need for API wrappers in other other
    languages other than Javascript. It's awesome to see the community
    provide third party libraries in their language of choice but it's also
    creating a major problem: security flaws.

    Most (all?) third party libraries that I have seen are creating http client wrappers around the endpoints described here:

    API docs describe opening accounts, sending LSK, voting and more. When
    you perform actions on the Lisk network you must provide your
    passphrase. These API docs describe sending that passphrase in the POST
    body of the request. This is a major security flaw for a variety of

    1. A hacker could easily intercept the request (man-in-the-middle) and instantly have access to all of your lisk
    An evil Lisk node could decide to save all request data in their own
    private database and have access to any lisk account that sent a
    transaction through that node via the HTTP api
    3. Most Lisk nodes are not using https
    4. A lot of variations on the above...

    the official client side library by the Lisk team never uses the API's
    which send a secret via http described in that document. Instead it
    implements Local Signing which securely signs these requests locally without ever exposing your secret over the network.



    Swift is a pure Swift 4 library targeting the Lisk 1.0.0 api, and yes,
    it includes Local Signing just like the official Lisk-js library. I am
    developing Lisk Swift based on the lisk-js 1.0.0 branch so when 1.0.0 is
    officially released it will be inline with the new API and best

    Instead of developing a simple wrapper around the Lisk
    HTTP api, I am aiming to provide something that can become a real
    backbone for Lisk apps on iOS, macOS, watchOS, tvOS and even Linux when
    using Swift 4.

    Lisk Swift can be installed via the Swift Package Manager right now. Cocoapods is coming soon.

    Current progress

    1. Accounts module, with support for securely opening a new account via a secret passphrase
    2. Loader module
    3. APIClient with all options from the lisk-js 1.0.0 branch

    Inam currently working on signing and broadcasting Lisk transactions to
    the network. Initially this will support Single and Second passphrase
    accounts with Multi-sig coming soon after. Once transaction signing is
    complete I will work on voting. Finally I will implement the remaining
    apis to search for delegates, blocks, etc. All of which don't involve
    local signing and should be much faster to implement.


    lisk-swift has over 80% test coverage. Tests continuously run on
    Bitrise on every commit. I am very proud of this, and will not accept
    any PR's that do not provide tests for all new API's implemented.


     I am developing a Lisk wallet for iOS which securely stores your secret
    in the iOS keychain, and uses lisk-swift to properly sign transactions
    locally using your secret once you authenticate with Face/Touch ID. The
    intention is to make the app a full replacement for Lisk Nano. You will
    be able to create new Lisk wallets in the app as well as backup your
    secrets securely to iCloud.


    If you'd like to support development, my number one request would be to
    submit issues and open PR's on the Github repo. It is critical I get
    more eyes on the actual code to help vet it's security and provide an
    API that developers actually enjoy using when developing their own iOS

  • Meet Lisk’s Freshest Faces

    Lothar, Eve, Iker and Manu

    Last year was spent sowing the seeds for major developments and changes that 2018 will bring to Lisk. We invested a great deal of time in our diligent search for top talent to add to the Lisk team. And we’re thrilled to say that we found some great people. Please read on to get to know our latest hires a bit better.

    Iker is the first member of our Science Team. He joined Lisk as a Cryptographer on December 11. Originally from Vitoria-Gasteiz in the Basque region of Spain, he received his PhD in Coding Theory. He also spent several years as a Software Engineer and Content Developer at MATLAB and Simulink maker MathWorks.

    He describes Lisk as groundbreaking, user-friendly and adaptable. Unlike the majority of his colleagues at Lisk, he is not a developer. He focuses on the mathematical foundation of Lisk’s protocol and algorithms. He seeks to improve Lisk by analyzing every issue and scenario from a theoretical point of view. He is most excited to see how Lisk will enable blockchain technology to reach everyone and believes blockchain is a technological revolution that is happening thanks to decentralization.

    According to Iker, Lisk should bring blockchain technology to the people because the concept initiates a financial, social and political revolution which will allow people to regain financial control over their lives. In his free time, Iker enjoys playing squash and football, as well as staying up-to-date with latest blockchain projects.

    Manu commenced his role as Lisk’s latest Backend Developer on January 2. He brings with him seven years of experience in Backend Development, with a specialisation in Node.js and JavaScript. The three words he uses to describe Lisk are: programmable gold coin. The most fun part of his job currently is learning about the domain and its technology, and he is looking forward to the release of Lisk’s SDK. Manu loves the fact that Lisk is built on JavaScript, therefore is programmer-friendly; it helps anyone and everyone build their own blockchain rapidly. Outside of the office, Manu is fairly athletic and plays basketball, volleyball and table tennis.

    Eve is a Human Resources Generalist at Lisk and began on January 3. Apart from Gina, she is the only other Berlin native on the team. Her previous work experience is in retail and community management. If she could only pick three words to describe Lisk, Eve would have to say that Lisk is: innovative, promising and ambitious. She loves the fact that her job responsibilities are defining and implementing company culture. Watching the team grow and expand is only the cherry on top. But what Eve is most excited to see is how Lisk will bring people together in the world of blockchain by making the technology easily accessible for all. In her down time, she enjoys stepping out of her comfort zone — she has plans to take a Salsa class soon.

    Lothar began working at Lisk on January 10 as a Financial Analyst. For him, Lisk is innovative, accessible and agile. He holds a Masters Degree in International Business with a specialization in Finance and most recently worked as a Business-to-Business Consultant. Among the many pluses of working at Lisk for Lothar is that he gets to be surrounded by an international and highly-talented team every day. Developers should care about decentralization and blockchain because they will both solve issues that society is currently facing due to a highly centralized world. Decentralization and blockchain will accelerate operational practices in various industries as well. Among his hobbies are playing football, financial modeling and aquatic sports like diving.

    Lisk is still rapidly growing. In order to accommodate the expanding team, we are moving into a much bigger office on February 1. Stay tuned to our social media channels to get a behind-the-scenes look of the new Lisk HQ and hear more about the Lisk team members who are hard at work every day to build a JavaScript-based blockchain ecosystem for all.

  • A Conversation With Lisk Backend Developer and SocketCluster Founder Jon Gros-Dubois

    Lisk Backend Developer Jon

    Jon joined Lisk as a Backend Developer last month. He is also the founder of SocketCluster, a software framework designed to simplify development of highly scalable systems, which can send and receive data in real-time betweens users and machines. We had a chance to sit down and chat about what he does at Lisk and learn a bit more about SocketCluster.

    Q: I noticed you have an interesting accent. Where are you from?

    A: I was born in Guadeloupe, a French island in the middle of the Caribbean. I lived there until the age of 11 before moving to Australia. I lived in Australia for many years, but settled in Europe two years ago.

    Q: When did you begin coding?

    A: I began coding about 14 years ago at the age of 14. I have experience in C/C++, C#, Python, Java, PHP, AVR Assembly, ActionScript and JavaScript. However, JavaScript has been my specialty since 2007; it is also my preferred programming language. I like JavaScript because it is flexible and expressive; it lets developers focus on logic rather than syntax and semantics. JavaScript’s flexible design has allowed it to evolve over time without ever breaking backwards compatibility; this means that JavaScript code, which was written over 10 years ago, can still run on all of the latest engines.

    Q: Why should people care about decentralization and blockchain?

    A: For the past 20 years, I have witnessed the increased centralization of everything. Companies have been getting bigger and fewer in numbers, resulting in a concentration of money and power in fewer hands. Government regulation in many countries has also made it difficult for small-time investors to participate in the growth of the technology economy. This has resulted in a large number of people being locked out of opportunities. Decentralization through blockchain will help to better distribute and allocate funding so that it is evenly spread out and accessible to more people. Blockchain projects achieve dominance by bringing people in instead of locking people out.

    Q: How would you describe Lisk?

    A: I think of Lisk as a decentralized democratic economy. Before joining Lisk, I spent a great deal of time researching the reach, flexibility, scalability potential and economic incentives of various cryptocurrencies. I believe Lisk ranks very high in all of these areas, which makes me very excited about its future.

    Q: What makes Lisk different from other blockchain projects?

    A: Lisk uses JavaScript; nowadays, most developers know JavaScript. This will be great for ecosystem growth. I believe that the structure of Lisk’s community/network will make it easier to reach consensus if/when it comes to big decisions. It should also lead to better outcomes. In addition to achieving scalability by offloading some of the workload to sidechains, Lisk’s Delegated Proof-of-Stake architecture should also make it easier to scale the mainchain if/when needed. Also, the fact that you can use your voting power to earn ‘interest’ on your Lisk holdings is brilliant. When you factor in sidechains, I think that Lisk will strongly reflect what an ideal economic system should look like.

    Q: How did you spend your time prior to joining Lisk?

    A: I was mostly doing contract work as a software developer/engineer for big companies and startups across different industries. At the time, I wasn’t sure which industry I wanted to specialize in, so contracting allowed me to try different areas. In addition to working full time as a software engineer, I’ve always kept an open source project on the side. Open source work is fun; you can find any problem that interests you and start to implement a solution for it. With open source work, there are no business constraints, therefore you can think very long term and pick very difficult problems. You can aim high and learn as you go. My first major open source project was a web content management system for developers; similar to Wordpress, except with a user-friendly drag-and-drop interface. It never became popular, but I learned a lot from building it, so it was still worthwhile. After that, in 2012, I started working with Node.js and that’s when I became interested in web application frameworks and real-time technology. This eventually led me to start SocketCluster. The common thread in all my open source work so far has been that I’ve consistently been working on platforms and frameworks for developers; to give them tools to build websites and systems more efficiently. Lisk feels like a continuation of that for me.

    Q: Tell us a bit more about SocketCluster.

    A: SocketCluster is a real-time (WebSocket) framework, a pub/sub data transport layer and a protocol. It makes it easier for developers to build highly scalable systems which can send and receive data in real-time between users and machines. It’s general purpose so it can be used for building many different things like chat systems, stock price tickers, trading systems and pretty much any other system/app which requires moving large amounts of data between clients and servers in real-time. I started SocketCluster several years ago because alternative solutions couldn’t scale beyond a single process on a single CPU core. CPU design trends meant that CPUs were getting more and more cores, so I felt that modern systems should be able to automatically make use all of these cores to get the best performance possible.

    Q: What problems does/will SocketCluster solve?

    A: SocketCluster can solve the problem of transferring a potentially unlimited number of real-time messages across a potentially unlimited number of machines/nodes using all available CPU cores on each machine. It can also be used in simpler configurations; it’s designed to be flexible and extendable. When a system only needs to process a few thousand messages/transactions per second, things are relatively simple; this is because that kind of processing can effectively be handled by a single CPU core running on a single machine. Once you go beyond a few thousand transactions per second, things suddenly get ugly. Past a certain point, no matter how much you optimize for performance, the code may not be able to process any more data; it might use up 100% of a single CPU core and leave all other cores on the machine essentially idle. This is partly because for many years, CPUs have not been getting any faster in terms of raw clock speed; they seem to have peaked at around 5 GHz (when overclocked). Recent CPU improvements have focused almost entirely on increasing the CPU core count which is currently approaching 72+ cores on commercially available high-end CPUs. Unfortunately, adding more CPU cores comes with a significant tradeoff; a program can only make full use of available CPU cores if the underlying task can be parallelized. ‘Parallelized’ in this context means that the underlying task can be broken up into smaller sub-tasks which can be processed in parallel (independently, at the same time) as opposed to serially (one after another). This constraint is also the reason why the blockchain has been so difficult to scale. SocketCluster’s pub/sub API supports scalable message passing across many machines/nodes. If setup correctly, it can scale linearly with respect to the number of messages as you add more machines/nodes to the network. SocketCluster shards pub/sub channels across available CPU cores and also across available machines on a network. SocketCluster basically opens up opportunities for Lisk to allow it to scale linearly to always be able to reach more users and to handle more transactions.

    Q: Can you describe a typical day on the job for you?

    A: I don’t know if I’ve had any typical days yet. I’m still relatively new to the Lisk team so I’m still in learning mode. There are a lot of details to absorb when joining an existing software project. I recently spent a lot of time writing tests; I spend a fair bit of time reading and running other developers’ code to understand how things work in detail. Being new to a project is challenging, but it’s also highly motivating.

    Q: What skills and technologies are you the most interested in improving upon or learning?

    A: My main areas of interest so far have been scalability and distributed systems. Now my focus is blockchain technology; there is a lot left for me to learn and it’s always evolving, so the learning will probably never stop. I like to come up with hypothetical strategies for scaling cryptocurrencies, therefore learning about all the main algorithms and architectures that are used in the industry is a good way to come up with creative strategies to solve various problems.

    Q: What is one piece of advice you would give to someone looking to pursue coding?

    A: You don’t need to be super smart to be a great coder; you just need to be curious, persistent and reasonable. It’s important to listen to other people’s opinions. When your code gets too clever or complex, it sometimes means you need to take a step back and consider alternative approaches. Coding is a social activity and there is rarely an absolute right or wrong way to do things.

    Q: What industry sites and blogs do you read regularly?

    A: I read a lot of tech-related stuff. Hacker News, Hackernoon, TechCrunch, VentureBeat, Reddit and lots of different blogs and publications on Medium.

    Q: What do you like to do in your free time?

    A: Aside from work, I enjoy contributing to open source projects, reading blogs, and hiking.

    Q: What is your favorite book and why?

    A: My favorite book is “Fooled by Randomness” by Nassim Taleb. It’s an interesting book about the role of randomness in life and in the markets. It gives a really good sense of how much more complex things are than they appear. This resonates with me because software development is often about mitigating the effects of chance and randomness; and that generally involves being exposed to a great deal of complexity that most people tend to miss.

  • The Lisk Community Survey Results Are In!

    Earlier this month, Lisk Community Manager Mat distributed a comprehensive survey to our community members in an effort to get better insight into their behaviors, attitudes and values. We plan to use this information to better address the needs of our community. We received an overwhelming response from 712 participants and are excited to share the findings.

    Firstly, we were interested in learning about the age range of our survey participants. As it turns out, half of them are between the ages of 25 and 34. The next largest group (20%) includes individuals between the ages of 18 and 24, while 18.3% of the participants are between the ages of 35 and 44.

    Although the majority of these individuals speak English (84.6%), German, Polish and Dutch are the other most prominently spoken languages. However, dozens of other languages are spoken by the participants.

    We also know that Lisk community members live in all corners of the world, including Australia, Japan, South Korea, India, Western and Eastern Europe, the UK, India and Scandinavia. But this survey indicated that a large portion of community members are located in Poland, Germany, the Netherlands and the US.

    The majority of our community members own over 1,500 LSK tokens (27%). More than 20% of our community own between 501 to 1,500 LSK, about 20% own 151 to 500 LSK, 14.2% own between 51 and 150 LSK, 12.1% between 11 and 50 LSK. Only 4.9% of the participants own under 10 LSK. A whopping 69.4% of the participants store these tokens in the Lisk Nano wallet. We always recommend storing LSK tokens this way.

    The majority of the participants first learned about blockchain technology the year Lisk launched — 2016. However, a fair number of them learned about blockchain as far back as 2010. Most of the participants learned about Lisk last year, but a great deal learned about Lisk in 2016.

    Regarding the most preferred social media channel for Lisk news and updates, it’s a tie between Reddit and Twitter.

    Now, let’s delve a bit deeper. What do our community members want to see us do this year?

    We learned that most people want to see Lisk Blog posts every week. We’re happy to say we are already achieving this — however, the frequency of blog posts will increase, as big plans are in store for the Lisk Blog. Following the rebrand on February 20, the blog will feature much more varied content, including in-depth and technical interviews with team members, community members and blockchain experts. We will also feature articles by guest bloggers who are passionate about Lisk, blockchain and JavaScript.

    Our community also wants Lisk to be more active on Telegram, Discord and Steemit. This is something we’ve immediately addressed. We went live on all three of these channels this week. The official Lisk Telegram and Lisk Discord channels already have 1,200 members and 1,000 members, respectively, and those numbers are rapidly growing.

    The survey participants have also asked us to reach out to the developer community more in order to ensure that JavaScript developers know about Lisk and its potential. Lisk has been very active on this front. We are conducting more interviews than ever before with JavaScript-focused publications and media outlets. In fact, Lisk Full Stack Developer Will was interviewed by JAXenter earlier this month. In addition, Lisk has plans to attend a number of JavaScript conferences this year. We will also be present at the Consensus 2018 conference in New York this May. We’ve reserved two booths and look forward to seeing many of our community members there.

    At Lisk, we aim to make blockchain technology accessible and understandable for everyone. To address this, we created the Lisk Academy. The Lisk team is hard at work creating this incredible educational resource. The Lisk Academy will debut on the new Lisk website on February 20. To those survey participants who have requested this, your wishes have been granted. Several community members have also requested for the Lisk website to be available in different languages. This is something we will address, as we are looking to grow non-English speaking markets this year.

    One participant requested that we build a Lisk Science Team. We have already hired the first member of the Lisk Science Team — Cryptographer Iker. Growing this team is a priority and we intend to hire many individuals this year.

    In addition, we plan to conduct Community Update videos where developers and members from the Lisk Marketing Team will discuss the progress of our products and initiatives. We will also answer questions from our community members in these videos. Community engagement is a priority to us at Lisk, which is why we recently added Community Managers Jan and Mat to the team. We will continue to maintain open lines of communication and transparency, as they are of utmost importance to Lisk.

    Thank you to everyone who participated in our first community survey. While we were not able to include all of the valuable responses to the survey in this blog post, we have discussed them at length internally. The feedback from our community members is highly valued, as it continues to steer us toward our ultimate vision.

    — The Lisk Team

  • Recap + Analysis: Lisk Relaunch Night

    Tuesday’s Relaunch Event at WECC in Berlin.

    This week marks the beginning of the new and improved Lisk. We’re beyond excited to enter this new phase, armed with a strong team, a supportive community, and a beautiful new website!

    The Relaunch Event brought 500 attendees to the Westhafen Convention Center in Berlin, while around 50,000 views were recorded during the event’s livestream, and around 12,500 people watched it at the same time at the peak. We understand that not everyone could join us in person; and regardless of whether or not you got to catch our livestream, we want to recap the evening with a comprehensive summary of vital points, as the evening was filled with many important and captivating speeches and discussions.

    Logo Reveal + Opening

    The new Lisk logo is an amalgamation our identity and ideals. We just couldn’t wait to share it with the world, so we kicked off the evening with our logo reveal video. Our incredibly talented in-house Motion Designer, Julian Alterini, created this piece; we look forward to sharing many more videos of this caliber with you in the future.

    Lisk co-founder and CEO Max Kordek gave the evening’s first talk, in which he provided a brief history of Lisk and discussed blockchain — its benefits as well as the current roadblocks we face in applying this technology.

    Max gave the evening’s first presentation
    “Blockchain technology could be used to remove borders, to empower future infrastructures or to bring transparency. Because of the fact that this technology is not very accessible nowadays, you need to know many different, complex fields like cryptography, peer to peer technology or game theory.”

    He went on to explain this very reason is what prompted Oliver Beddows and Max to start this journey — to make this technology accessible to everyone in the world. He concluded the opening speech with the Lisk promise to everyone:

    “Due to our extremely hard effort and a lot of time spent on this project until now, Lisk is stronger than ever before. We are prepared to make 2018 the best year we’ve ever seen yet.”

    Lisk Brand and Identity

    Following Max’s inspirational talk, Rlevance brand strategist Christian Vatter took to the stage to discuss how Lisk came to find its new identity and approach its new brand.

    Christian Vatter of Rlevance.

    Christian revealed that as part of his role, he dug deep into the topic of blockchain in every way possible. Among the biggest goal was to make sure that the Lisk message is clear to everyone outside of the community — what Lisk is and why Lisk is doing what it is doing.

    The way in which Christian helped Lisk find focus and live in its truth was to take a human-centered business approach. This means understanding its users while implementing business thinking and marketing creativity.

    The journey began with the goal of understanding the potential of blockchain technology, the special qualities of Lisk and most importantly, its users’ needs. Christian held a series of workshops and interviews with Oliver and Max to pin down their motivations, goals, unique vision, as well as the strengths and features of the Lisk product. Christian also created a Slack channel where blockchain developers could discuss their needs and what they feel the strengths of Lisk are. This channel brought in over 2,000 posts in one week alone.

    Lastly, Christian held one-on-one interviews with experts including ICONOMI co-founder Jani Valjavec (on the topic of blockchain philosophy), Head of Trading at Bitcoin Suisse AG Fabian Hediger (on the topic of financial aspects of blockchain), Wachsman PR founder David Wachsman (on the topic of public perception of blockchain), Head of Strategic Future Projects at Mercedes-Benz Christoph Farber (on the topic of corporate applications of blockchain) and Investor and Entrepreneur Thomas Schafbauer (on the topic of blockchain for business owners).

    The three most vital conclusions that Rlevance came to following its comprehensive research was that -

    “Lisk is a reliable and scalable platform to run blockchain applications.”
    “Lisk makes creating blockchain applications more accessible.”
    “Lisk wants to bring the benefits of blockchain applications to everyone.”

    These insights led to Lisk’s value proposition -

    “We enable blockchain creators.”

    Lisk will enable blockchain creators by making apps easy to build with a Sidechain Development Kit (SDK), continued education on the topic of blockchain, inspiration with use cases, and much more. Lastly, Lisk will continue to uphold a solid and scalable infrastructure.

    Presenting the New Lisk Ecosystem

    Following Christian’s powerful presentation, Lisk Marketing Lead Thomas Schouten presented the audience with how the brand identity translated into products and design.

    Thomas kicked off his presentation by explaining the multiple processes Lisk conducted as part of its rebrand — the strategy phase with Rlevance which began in March of last year, the design phase with Taikonauten which began in June, and the in-house development phase which began in November. We organized focus groups with our main stakeholders to conduct user testing and get insights into what we were missing.


    Thomas presents various features on the new Lisk website.

    After that, Thomas revealed the new and improved names of the Lisk products. Although Lisk Core will retain its original name, Lisk JS is renamed Lisk Elements, Lisky is renamed Lisk Commander, and the Lisk App is renamed Lisk Hub.

    He also showed the world the beautiful Lisk Rebranding Video, also made by Julian, highlighting all the incredible facets of our new website.

    He then carefully walked the audience through the new website, which was designed with different users in mind — newcomers to blockchain, developers, app commissioners and our greater community. He walked the audience through the different features of the Lisk Hub, including the Wallet and Explorer.

    Our community can expect to see much more from us, as Thomas explained. These include a ramp up of video production for our YouTube channel. We will also hold many more curated events for beginners and blockchain experts. Read our newsletter for the latest developments at Lisk.

    The Lisk Academy

    Following Thomas’ presentation, Project Lead of the Lisk Academy, Jacob Kowalewski, took to the stage to present what he has been working so diligently on for the last several months. An educational one-stop shop for all things blockchain, the Lisk Academy is completely free-to-use.

    Jacob presents the Lisk Academy.

    Currently, the Academy is divided into Blockchain Basics and Blockchain Business.

    Blockchain Basics includes four chapters — Blockchain Explained, Technologies of Blockchain, Values of Blockchain and Blockchain Use Cases. Blockchain Business includes four chapters — Blockchain’s Uses in Business, The Blockchain Business, Cryptocurrencies and ICOs.

    The Lisk Academy currently features more than 40,000 words of premium content, and over 50 infographics and animations to keep learning fun. The goal of the Lisk Academy is to raise awareness of blockchain technology, as well as increase acceleration and adoption of this technology.

    Looking ahead, the Lisk Academy will also feature a Blockchain Builders module, covering how to develop blockchain applications and support them. Jacob explained his belief that using gamification to teach blockchain will also be incredibly helpful, especially in teaching blockchain technology to younger people. Jacob also presented an incredibly informative video about blockchain.

    The Lisk Academy also has future plans to sponsor educational meetups for both developers and blockchain beginners. There are also discussions regarding an accredited Lisk diploma for learners to demonstrate comprehensive knowledge of blockchain technology with the help of the Lisk Academy.

    Development Update

    The final segment of the evening was a development panel discussion featuring Lisk co-founder, Vice President and CTO Oliver, Fullstack Developer Will Clark and Cryptographer Iker Alustiza.

    Thomas, Oliver, Iker and Will (from left) participate in a development panel discussion.

    The discussion opened with a very informative video explaining the Lisk platform, sidechains and the SDK.

    Oliver explained the motivation behind the development of Lisk Core 1.0.0. He explained that what Lisk wants to achieve is a truly scalable and accessible blockchain app platform. The goals of Lisk Core 1.0.0 are to design and implement a new API, rewrite the peer to peer transport layer, rewrite the database layer to support fully atomic block writes, add a 64 byte data field to our type 0 transaction type, and form a standards team within Lisk HQ.

    Lisk Core 1.0.0 has been a tough but rewarding process with incredible statistics — 375 merged pull requests, 323 closed issues, 36 contributors, and 3020 commits (which is more than all previous releases put together). And finally, Oliver revealed that the world can expect an open beta release within the next 4–6 weeks.

    Following the release, further modularization work will take place, which will involve decoupling the various parts of Lisk Core into pluggable components. This will form the basis of the SDK and the blockchain application platform.

    The focus then moved to Iker, who spoke about Lisk’s plans for a new and greatly improved fee system. This is what he has been working on for the past few weeks — a scalable and dynamic fee system. The new fee system is going to be the main priority for the Core team after the successful release of Core 1.0.0.

    Will discussed Lisk Elements, a JavaScript library which gives developers access to Lisk-related functionalities. Lisk Elements contains the following components: transactions, API, Constants, Cryptography, Passphrases.

    Will then moved on to describe Lisk Commander and what we can expect from it in the future. Lisk Commander, which gives a basic set of commands that developers will want to use when interacting with the Lisk network, to be the primary interface for dapp development. There will be packages within Lisk Elements for creating sidechains, and once we have the functionality, there will be a command in Lisk Commander to provide a nice interface to get going from the Command line with sidechain development.

    Oliver provided an overview of the steps it takes to go from a simple idea to a realized app. The steps are the following:

    1. Generate your own white label sidechain.
    2. Customize your sidechain.
    3. From sidechain to application.
    4. Test, deploy and promote your app.

    If you would like to read in much more depth about these steps, please visit the Products page on our website.

    Oliver explained technical components in-depth, such as the fact that Lisk sidechains are essentially API-driven backend applications, similar to Lisk Core itself, therefore developers will have freedom to choose how their users will interface with their sidechain. The SDK will provide an out-of-the-box framework for writing automated tests against your sidechain code. Lisk will also be developing standards and best practices for testing blockchain applications effectively.

    Internal Updates and Closing Remarks

    After an incredibly in-depth and technical panel discussion, Max took to the stage for a final presentation. He provided the audience with an update on the latest company financials. The Lisk Foundation has a total value of 300,000,000 CHF. He moved the discussion to open source projects, such as Jon Gros-Dubois’ SocketCluster and Vitaly Tomilov’s Pg.promise. Both of these individuals are incredibly talented developers and huge assets to Lisk. Lisk has great plans to bring on much more talented staff, with a hope to double in size in 2018 alone. We have many open positions; if any of these positions captivate you, please apply here.


    The entire Lisk team and Lisk contractors on stage.

    Following the conclusion of Max’s presentation, the entire Lisk team, as well as all of the contractors Lisk worked with to make the Relaunch a reality, took to the stage. It was such an inspiration to stand on that stage and feel the energy that permeated the room on Tuesday evening.

    But there was one more thing we had saved for the very end of the evening — a video created by Element E, a film production company, which we hope will inspire people everywhere to become blockchain creators.

  • Lisk Integrates Intercom for Improved Customer Support

    Here at Lisk, we believe community is everything. From the early days of Lisk, founders Oliver Beddows and Max Kordek established the project with the community in mind, and instilled customer-centric principles that guide the team to this day. To further improve the quality of user experience, the Lisk team set out to find the best possible method for customer support. After long and careful consideration, we’ve decided to go with Intercom — a modern platform that allows for instant messaging between users and customer support representatives.

    The main factors that we took into account when comparing our various options were improved response time and increased transparency. Intercom allows us to simplify the customer support process on both ends: for users seeking assistance and customer support representatives answering questions.

    As the largest software companies in the world continue to heavily invest in self-service solutions, the Lisk team decided it was time to follow suit. The initial stage of the process was to create the Help Center. The Help Center contains comprehensive answers to often-asked questions regarding the company, products and general troubleshooting. The Help Center’s search bar allows users to more quickly locate their topic of interest, but also allows for customer support representatives to better suit customer needs, as they are able to see all query searches that have been made. Because of this, customer service representatives will know which articles to add to the Help Center in case they have not yet been addressed.

    One of the main features of Intercom that is invaluable is the live Chat Box. If you cannot locate the answer you need after using the search bar, all you’ll need to do is click on an icon — the sad smiley face — and a chat box will automatically appear, prompting a conversation with one of the available customer support representatives. If no one is available at the time, we will receive your message in our dashboard and a response will be sent to your email address. If you want to contact the support team right away, you can click on the chat icon in the lower right hand corner of the page to immediately alert us about the issue. You can even see how long you could expect to wait before you hear from us; this is calculated daily based on our response time in the last seven days. We always strive to answer questions within one hour.

    The team tested Intercom for several weeks before our relaunch last week. The new Help Center went into effect at the same time as the new Lisk website. We’re currently amidst forming a customer support team dedicated to answering all questions — technical and operational. If you’re interested in joining the customer support team, please send your resume and motivation letter to [email protected]

    Following the Lisk Relaunch Event last week, we have seen an increase in fake Lisk accounts running fraudulent competitions.

  • Introducing Lisk Template

    Bootstrap script for Lisk Template.

    Lisk is an open source blockchain project. Whenever you’re working on blockchain technology, security is always a priority. And when your project is open source, you want to make it as easy as possible for your developers — whether in-house or part of the wider community — to contribute good code.

    With both of these aims in mind, we’re always looking to improve our code standards. We’re pleased to introduce our community to our repository dedicated to improving and coordinating standards across the Lisk ecosystem: Lisk Template.

    Coordinating standards

    The main aim of the Lisk Template repository is to coordinate the adoption of standards. It consists of:

    1. A default directory and file structure.
    2. A default package.json file, including project information, npm scripts and basic dependencies such as our ESLint configuration.
    3. Configuration files for various tools, including those dependencies.
    4. A skeleton test setup, ready to get going with our Mocha BDD package if desired.
    5. Basic documentation files, including our usual preferred license.

    The README.md for the project provides information on many of the standards gathered here.

    The standards present here have largely been derived from the practices we’ve been following in the various projects in the Lisk ecosystem. Projects like Lisk Commander (formerly Lisky) and Lisk Elements (formerly Lisk JS) have smaller codebases, so they often play the role of testing ground for new code standards or tools we’re considering using. Once we have this experience, and decide we like such a standard, we add it to Lisk Template, and the new standard can be rolled out to the other Lisk projects as and when it’s appropriate. (There are inevitably project-specific idiosyncrasies which might mean a given standard doesn’t make sense for every project.)

    We want to foster discussion about standards, and we encourage everyone who has ideas about how to improve code standards at Lisk, or tools we should be using, to open an issue on the Lisk Template repository.

    Bootstrapping new projects

    The other major use case for Lisk Template is bootstrapping new projects. Since the repository already includes a list of dependencies and configuration, it’s the ideal way to start a new project. We’ve included a handy script to help you initialize a new project. Full instructions can be found here, but you can create a lightly customized project skeleton by running the following command with your GitHub username and the name of your new project:

    Bootstrap a new Lisk project!

    We already used this script at Lisk HQ to create the Mocha BDD repository, and will use it to start fresh projects going forward. (You will obviously have to replace our details with your own in the package information and license etc.)

    Getting involved

    As part of Lisk’s mission to make blockchain technology accessible to all, we want to make it as easy as possible for developers to create decentralized applications. That covers not only the platform on which those applications are built, but the tooling used in their creation.

    We would love to see our community members starting new projects (Lisk-related or otherwise!) using the Lisk Template bootstrapping script. Any feedback we receive now will be invaluable when it comes to helping people create sidechains later on.

    And if you’ve got ideas about how to improve Lisk’s standards, please open an issue or get involved in the discussions on the Lisk Template repository.

    Happy bootstrapping!

  • Lisk Community Update — February 2018 | Relaunch Event, Development Update & more

    February at Lisk HQ was busy, productive and full of progress! The majority of the month was dedicated to preparing and ensuring a hugely successful Relaunch Event. However, we were able to make strides in each department.

    The Community Update for February will cover the following:

    • Relaunch Event
    • Development Update
    • Marketing Update
    • Community Update
    • Company Update
    • Next Steps

    Relaunch Event:

    Launching the new and improved Lisk in front of family, friends and most importantly, our dedicated community, was a truly rewarding experience. With the WECC in Berlin as the perfect backdrop for such an event, we were able to showcase the revamped website, logo, the Lisk Academy, new product naming as well as discuss the next steps for the development team. Given how many people traveled from the far corners of the world to join us, it was even more special to share this moment, as it highlighted their contribution to driving awareness of Lisk’s mission. There was an enormous sense of pride looking back at all the work that allowed us to reach this point; but we recognize that this is only the beginning.

    Development Update:

    • The development team continues to approach each day with a laser focus on Core 1.0. We are expecting it to be complete within 4 weeks.
    • We unveiled the Lisk Hub on February 21. It is a one-stop shop for managing your LSK tokens and partaking in the ecosystem. The Lisk Hub can be accessed via your desktop or by downloading the App.
    • Fullstack Developer Shusetsu Toda joined the team and has already had an immediate impact on development.
    Source: GitHub

    Marketing Update:

    • Fresh content was key in February. Alongside our video partner Element E, we released our new homepage video entitled Create the Future, which depicts a visual representation of our mission —a future of decentralized applications that tackle society’s challenges made possible by Lisk.
    • Our very own all-star Motion Designer, Julian Alterini, created a range of dynamic videos outlining the following: What is Lisk?, Lisk Academy: What is the Blockchain?, Lisk Academy: Is the Blockchain Safe?. With a clear visual strategy outlined for the next few months, you can expect much more activity from Julian.
    • The Lisk Academy was released following the Relaunch Event, and just after two weeks of gathering website data and user feedback, we can see that this project is clearly a community favorite.
    • Expand Online, our online marketing contractor, assisted us in planning and deploying paid advertising campaigns on Adwords starting in January with great success. The focus is to drive quality traffic to the new website and we will continue to optimize these campaigns and test a multitude ad copy and keywords.
    • Additional paid marketing campaigns were launched on February 21st, which are being managed internally at Lightcurve. There are several goals to these tests beyond general brand awareness, such as gathering strategic insights about target audiences.
    • The Lisk Relaunch YouTube Livestream was filmed and uploaded as a courtesy from our video partner, Boomerang. Also, our friends at CoinPost have now added Japanese subtitles.
    Lisk Community Growth for February 2018

    Media Update:

    Max Kordek was interviewed by Crypto Love
    Max Kordek was interviewed by BTC-ECHO (in German)
    Max Kordek, Jacob Kowalewski and Maciej Baj were interviewed by Maciej Wieczorek of Cryptomasters
    Thomas Schouten was interviewed by Crypto Lark

    Community Update:

    • Following the Relaunch, the Lisk team universally agreed that networking with community members was incredibly inspiring; this will definitely have a long-lasting impact.
    • We are continuously adding events to our calendar for the remainder of the year — if you would like to see where you can meet our team next or would like to check out a local Meetup, visit our events page.
    • Our in-house designers, Bart and Julian, created Lisk Wallpapers for desktop and mobile.

    Company Updates:

    • After an enormous community-driven effort, Lisk debuted on exchange BitIndia and received an invitation to join EUcoin.
    • With the growth of the Lightcurve, we have decided to split up into teams for our morning stand-up meetings. We’ve also introduced a company-wide meeting that will occur on a monthly basis. This ensures communication is streamlined and allows for a look back at the previous month and outline the roadmap for the upcoming month.
    • On the personnel front, we’ve welcomed two new members in February.
    Celina started working at Lisk as an Office Manager on February 20. She is originally from Switzerland but has lived in Berlin for the last six years. Music is a passion of hers; prior to joining Lisk, she worked in the music industry managing artists and events. At the moment, she is reading “Dieses bescheuerte Herz” by Lars Amend. Her hobbies are cooking, spending time in the countryside, listening to music and kicking back with a good book.
    Shusetsu began working as a Fullstack Developer Lisk on February 7. He is originally from Japan. He spent five years developing web applications, mobile games and business applications as a Fullstack Engineer. He also worked as a lead engineer on several projects and led a company as CEO. His favorite book is Kafka On The Shore by Haruki Murakami. When he’s not at work, he enjoys playing tennis and watching movies.

    Next steps:

    The team is finally united on the top floor at WeWork. Expect the Lightcurve team’s impressive output to continue!

    And finally, thank you to everyone for the continued support — thank you to all of those who watched the Relaunch Event in person, live or recorded — we are inspired to be continuing this journey with our community.

  • Lisk Future in Focus: Madana

    Disclaimer: The Lisk Foundation in no way endorses projects that are interviewed for the series.

    We are excited to present to you the first of our Future in Focus series, a new initiative from Lisk HQ spotlighting promising blockchain projects around the world with up close and personal interviews.

    This week, we’re featuring Berlin-based MADANA. MADANA (Market for Data Analysis) allows everyone to participate in a fair data market while protecting privacy by design. The PAX (Privacy-Analysis-Exchange) smart token enables anyone to buy data analysis results from MADANA’s decentralized pool of information, while rewarding data producers and plug-in providers for their contributions.

    The ICO of MADANA is expected to be the first one launched on the Lisk platform. We had the chance to speak with co-founders Christian Junger and Dieter Schule to learn a bit more about the project.

    Jennifer: Please tell me a little more about the history of MADANA and your relationship to blockchain technology. Why did the founders decide that the world needs MADANA?

    Christian and Dieter: We originally discovered blockchain technology through some early discussions we participated in on Reddit. We were fascinated by the idea of a decentralized and fully transparent method for the storage and exchange of value — most popularly demonstrated by Bitcoin. That is why part of our team founded the Bitcoin Meetup with Lisk founder Max Kordek in 2014. The foundation of MADANA began with our co-founders’ previous startup, which was founded while studying at RWTH Aachen University in 2016. This startup was centered around the idea of utilizing data from the retail market and processing it with modern analytics tools. The goal was to offer an all-in-one solution for automated point-of-sale, supply-chain and inventory management in the retail sector by digitizing every clothing item. Therefore, handling huge amounts of data and incorporating complex database systems were a substantial part of the initial stages of the business. While working on the project, we found no existing industry standard that met our requirements of data security, privacy protection and a fair rewarding system. That’s why we started developing our own model, embracing privacy by design and providing a fair share of the value for every participant. Rethinking data analysis itself is what led to the founding of MADANA. By gathering talented people from related sectors like data security and blockchain development, we formed a skilled and highly motivated team to realize the vision of MADANA; a fair data analysis platform, protected with privacy by design.

    Jennifer: What issues does the data market currently face? What about when it comes to privacy?

    Christian and Dieter: There are three main issues that are putting privacy and data security at risk: centralization, one-sided business revenue models, and a lack of transparency. Centralization always comes at the cost of privacy and security. When you have large corporations collecting huge amounts of valuable data, the interest by malicious parties and the chance of data breaches will continuously rise. Moreover, it is only natural for a company to leverage their power for holding such a valuable asset. Unfortunately, when the goal is to maximize profits in a market with few competitors, the less powerful voices are the easiest to neglect. One way to solve this problem is to redistribute power to all participants and bring back data ownership to the data producer. And finally, regarding the lack of transparency, it’s not about money, it’s about our self-depiction on the Internet. Who really knows how our data flows into different analyses of a multitude of companies all over the world? How can we be sure that it is not getting copied? We think blockchain-based distributed ledgers have the power to reshape our future for the better. We don’t need to trust empty promises anymore, but instead, can rely on the transparent execution of code utilizing smart contracts.

    Jennifer: What problems will MADANA solve?

    Christian and Dieter: Considering the three issues we just mentioned, MADANA is going to tackle them with a blockchain-based solution, using the Lisk Sidechain Development Kit, as well as privacy by design measures. Ultimately, the value of MADANA lies in the infrastructure we will build with the following elements: a data-managing solution for data producers; a platform that brings all involved participants together; a computing environment that ensures data security and privacy protection; finally, tools for analysts to create data analysis plug-ins one can easily leverage for business, scientific or governance needs. The fair distribution of rewards will be handled by PAX, the privacy analysis exchange token of MADANA.

    Jennifer: Who do you have plans to collaborate and work with to achieve these goals of creating a better world?

    Christian and Dieter: Over the past year, we established a strong relationship with our advisors, who are helping us reach industries that are most relevant for the MADANA platform. For example, given Max Kordek’s experience with founding a startup, he helped us in our initial stages and introduced us to his network in the blockchain scene. Several partners are connecting us to politicians, while others are helping us with their domain-specific expertise. Of course, in a monopolized data market, we can face a great deal of resistance. Therefore, our success is also dependent on having active advisors, well-known industry partners and influencers. We are incredibly grateful to already have such a skilled and actively supportive network that we can rely on.

    Jennifer: Where do you envision MADANA will be in five years?

    Christian and Dieter: In the future, MADANA will be used in a multitude of contexts and have the ability to utilize various types of data and analysis plug-ins. Differently-sized corporations and many individuals will contribute data on their own behalf. Following tighter legislation, as well as a better understanding of data value and privacy protection, MADANA will become the industry standard platform for data analysis. We imagine it to be the trusted label for fair data collection and processing, similar to the BIO label for fairly-traded and sustainably-produced food. At the same time, MADANA will enable analysis experts to work with relevant data and help provide analysis results to everyone. In today’s rapidly developing world of blockchain technology, five years is a long time. We at MADANA are eager to make this vision a reality in the years to come.

    Jennifer: How do you anticipate blockchain technology will change the world? What is its potential?

    Christian and Dieter: The currently centralized model governing some of the most important aspects of society today, like value transfer, vote collection, or proving one’s identity, is not keeping up with requirements of the modern world. We are reaching a point where the globalization phenomena is colliding with old dogmas of nationalism and centralized banking. For the first time in history, distributed ledger technology offers us sufficient self-regulation. It has the potential to eliminate corruption, encourage social behavior and a stronger collaboration between countries; many describe this technology as the next generation of the Internet. We want to contribute towards this next generation and better world with MADANA.

  • Meet the Lisk Academy

    The Lisk Academy, a comprehensive, unbiased and entirely free educational platform solely dedicated to the subject of blockchain technology debuted last month at the Lisk Relaunch event.

    Lisk will be the platform that enables the everyday adoption of blockchaintechnology. However, the roots of real adoption run deeper than simply opening the doors of blockchain to the JavaScript developers of the world. True adoption stems from simplification - making what seems like complex concepts understandable to everyone, whether it be a five year old or an 85 year old.

    The first step to adoption is awareness. The second step is understanding.

    Due to the hype surroundingcryptocurrencies, which are built on the technology of blockchain, awareness isn’t the problem. The industry experienced parabolic growth at the tail-end of 2017, propelling cryptocurrencies into mainstream perceptions, albeit with a misguided notion of what the technology actually has to offer.

    The manner in which the mainstream currently discusses blockchain is not dissimilar from the “What is the internet, anyway?” conversations that were taking place in the nineties. Currently, the narrative circles around misinformed and obsolete debates about the volatile price of Bitcoin. Such debates only hinder adoption and it is the responsibility of those who understand the technology to shape and steer these conversations. They should do this not for self-interest, but for the sake of the industry as a whole, as well as for the billions of people who stand to benefit from the adoption of this generation-defining technology.

    It is this steadfast belief that led to the founding of the Lisk Academy.

    The Lisk Academy is an honest and educational platform with detailed yet concise content catering to the modern attention span.

    A great deal of effort has been dedicated to the Lisk Academy and there will never be a premium option requiring payment. The Lisk Academy is and always will be an open and entirely free educational platform for all blockchain needs.

    The Academy is divided into two modules, Blockchain Basics andBlockchain Business. As the name suggests, Blockchain Basics covers the fundamentals of blockchain technology, ranging from the P2P network to the concept of a trustless system.

    Just ten minutes of reading the Academy can equip anyone with the ability to explain blockchain technology to others without the need for any prior knowledge. At this point, the majority of sources of information about blockchain technology are either too technical or simply shameless marketing schemes. The Lisk Academy, especially Blockchain Basics, aims to carve a more equitable path to understanding the technology.

    With awareness and understanding comes adoption, and the Lisk Academy also seeks to facilitate this through the second module, Blockchain Business. This part of the Academy is tailored for those who understand the fundamentals of the blockchain, but are still unsure about its real world applications. The subjects covered include implementing blockchain technology within a traditional business model, as well as cryptocurrencies and ICOs, both to provide insight for investors and inspire potential founders.

    The Lisk Academy contains 69,000 words of premium content and over 50 custom infographics and animations made in-house. With this number increasing on an almost daily basis, anyone can begin mastering blockchain technology, regardless of what level they are starting from.

    Along with informative infographics and animations, the Academy features interactive elements designed to make the learning experience as engaging as possible. These include expandable segments, distinct tips, warning signs and a detailed blockchain glossary, combined with a tooltip feature, to ensure any technical terms can be explained by simply hovering over a word.

    Like blockchain technology, the Lisk Academy is still in its infancy and has limitless potential to develop and grow. As such, any feedback or suggestions, no matter how small, are welcome and very much appreciated at [email protected].

    Look out for the next Academy blog post detailing upcoming plans for the Lisk Academy.

  • Lisk Hub Release Update

    Lisk Hub

    As part of the Lisk Relaunch, we introduced a new addition to the portfolio of Lisk products. Made for everyone, Lisk Hub is a desktop and web app for interacting with the Lisk network.The purpose of this blog post is to summarize the current state and future plans for Lisk Hub.

    Lisk Hub 0.1.0

    After several months of working behind the scenes on Lisk Hub, we published the source code and released the initial beta version 0.1.0 on February 21. We strongly believe in the benefits of open source development and community feedback. For that reason, we made it public as soon as we could. The features of the initial version include the Dashboard, Wallet, Explorer, Delegates and Multi-Account Management.

    Lisk Hub Release Cycle

    Lisk Nano and other Lisk products have different release cycles than Lisk Hub; these products’ releases are defined by the set of new features they contain. This approach means that when even just one of the new features is delayed, the entire release is delayed; end users cannot benefit from all the other new features that are already ready to use, but must wait for the release. With Lisk Hub, we decided to set a regular release cycle to bring new features to our users earlier. For example, if only one new feature is not ready, only this one feature will be postponed until the next version is released.

    For Lisk Hub, there will be a feature freeze for a new release candidate (RC) every two weeks, namely 0.2.0-rc.1, which was done on March 2 and 0.2.0-rc.1, which will be done on March 16. The RC is publicly released with the desktop version on Github and the web version is deployed to dedicated RC hostings: https://lisk.io/hub-rc for Mainnet, and https://testnet.lisk.io/hub-rc for Testnet. There is a testing period of one to two weeks when we test the RC, report bugs, fix the bugs, and potentially carry out follow-up RC releases. After all the bugs are fixed, we do the final release (like we did today), the desktop version is published on Github and the web version is deployed to https://lisk.io/hub for Mainnet, and https://testnet.lisk.io/hub for Testnet.

    An exception to this release cycle will be a major release of Lisk Core. In the near future, it will be Lisk Core 1.0.0, which makes changes to its API, therefore we will have to release Lisk Hub 1.0.0 at the same time; the old Hub will not be able to communicate with the new Core.

    Lisk Hub 0.2.0

    We released Lisk Hub 0.2.0 today. The main goal of this release is to improve test coverage so that we can do bi-weekly releases with confidence that we are not breaking any previous features. One part of this goal is to add more automated tests; another part is code refactoring of any code that has code quality issues. Last but not least, the release contains a number of bug fixes for some edge cases that slipped into the initial 0.1.0 release.

    Where Lisk Hub is Headed

    We always strive to improve the code quality of Lisk Hub. For that reason, we will do more test coverage improvements and code refactoring in upcoming releases. But the main focus will be to add new features. We will go more in-depth about each of them when they are released, but for now, here are some that are at the top of our list:

    • Account initialization
    • Second passphrase registration
    • Delegate registration
    • Launch protocol for send and vote
    • On-boarding process that explains the UI elements of Lisk Hub
    • Receive LSK
    • Support for delegates in Explorer section

    As mentioned earlier, we are doing regular releases, therefore the features are not pinpointed to a particular release. For the latest information on our plans, you can always view our upcoming releases in Github projects of Lisk Hub.

  • lisk Blockchain Buzz: Healthcare

    Solutions to the Healthcare Industry’s Woes Lie in Blockchain Technology

    Blockchain Buzz is debuting on the Lisk Blog this week. This series will highlight and investigate different industries that are making real moves towards the adoption of blockchain technology. The first article of the series explores blockchain in healthcare.

    The benefits of blockchain technology are expected to reach and transform a number of industries, ranging from agribusiness to real estate. However, it is fair to say that one industry in particular is rapidly moving towards adoption of the technology — healthcare. As the Lisk Academy points out in its comprehensive section dedicated to Blockchain in Healthcare, “the industry is one of the most proactive and excited about switching to a blockchain healthcare system with over a quarter of stakeholders surveyed by the research company Deloitte disclosing an investment of over $5 million or more into the space.”

    Not only is the healthcare industry antiquated, the issues surrounding the bureaucratic red tape that plague the industry are also cumbersome. There exists poor interoperability and a lack of proper data management and analytics.

    The United Nations Department of Economic and Social Affairs published a news brief this month stating the need for more and trustworthy data as “accurate data is the lifeblood of good policy and decision-making,” according to UN Secretary-General Antonio Guterres.

    Earlier this month at the HIMSS18 conference in Las Vegas, one of the most important conferences in the world for health information and technology, Eric Schmidt, former executive chairman of Google, discussed the current state of the healthcare industry and why it desperately needs to utilize innovation. “We’re in the Stone Age now” as “80% of referrals and insurance interactions seem to be done by fax,” he cited. In addition, doctors spend “two hours of admin time for every one hour in front of the patient…no wonder 50% of the physicians report burnout,” he said. Schmidt cited another problem as “alert fatigue — they’ve got so many different systems that are not particularly integrated that all these alerts are going on.” The plethora of benefits associated with data analysis cannot be tapped without the use of innovative technologies that are available to us.

    Schmidt referenced previously unthinkable innovations such as email, the internet and smartphones, calling for a “killer app” to change the industry as we know it. As HealthcareITNews summarized, what it will take is “a clinical data warehouse packed with diverse data sets that are curated and normalized such that sophisticated analytics can be run against the data and accessed with a rich API.”

    It’s easy to imagine that this “killer app” will make use of blockchain technology: a decentralized system incentivizes convergence on a single standard, making it easier for data consumers to interact with data from diverse suppliers.

    There are a number of blockchain technology companies working to improve data exchange. For example, Berlin-based Ocean Protocol is a decentralized data exchange protocol working to make data universally available for applications in AI and much more.

    As one can imagine, blockchain for healthcare was a hot topic at HIMSS18. During a panel titled “Blockchain 4 Healthcare: Fit for Purpose?” industry experts including the likes of Tim Mackey, director of the Global Health Policy Institute at UC San Diego, and Health Linkages CEO Robert Barkovich discussed the natural applicability of blockchain in their industry. According to an article by HealthcareITNews, Tim Mackey stated that “some of the core principles of blockchain apply to healthcare,” and “this immutable distributed ledger can better ensure the resilience and provenance, traceability and management of healthcare data.” Barkovich added that “blockchain lets us agree on history, even if we don’t all agree or trust each other” and “there’s no need for a trusted third party — it’s all there in the chain.” He explained “by its very nature, blockchain is well-positioned to be part of a solution to many problems in healthcare.” Blockchain technology supports interoperability and seamless exchange of health information.

    One company present at the conference, TrustedHealth, a blockchain-based specialized medicine digital ecosystem for physicians and patients, is “completely digitizing and decentralizing the healthcare process on the blockchain” with a focus on life-threatening and rare diseases. They hope to enable patients to receive the correct information regarding their condition by connecting them with the specialists they need. As the healthcare news outlet stated, TrustedHealth “enables virtual conversations and knowledge sharing while simultaneously gathering Big Data to be used to further research into specific conditions.”

    Developers and health professionals are not the only ones who understand the implications of blockchain technology for the healthcare sector; investors are taking notice too and pumping a great deal of money into healthcare-focused blockchain companies. In January, San Francisco-based startup Akiri, which runs a blockchain-based network-as-a-service platform for the healthcare industry, scored $10 million in funding from Health2047. Health2047 is an innovation enterprise developing and commercializing solutions for data liquidity, chronic care, productivity, security, and payments for the healthcare industry. The American Medical Association (AMA) is one of the founding members of the enterprise.

    Just this month, Millennium Blockchain, a US-based diversified holding company focusing on blockchain technologies and crypto-assets in financial markets, healthcare, crypto-mining and high technology sectors, signed a deal with BurstIQ in which it invested $5 million. Health data not only exists in silos but is also bound by HIPAA (Health Insurance Portability and Accountability Act) regulations, making it difficult to share the information. BurstIQ is attempting to solve these challenges by leveraging blockchain and machine intelligence to allow data to be brought together in a repository for efficient sharing. BurstIQ is HIPAA-compliant.

    While there is a great deal of investment in blockchain startups, many companies are choosing to develop the technology internally. At SXSW HealthSpark last week, Palo Alto, Calif.-based Medable Inc., an app and analytics platform for healthcare, announced INSIGHT, a blockchain-powered platform that enables medical data exchange among patients, medical researchers and biopharmaceutical companies. Medable is launching this blockchain network in order to combat low research participation for new drugs as well as inadequate public funding for research and a lack of meaningful data sharing among research groups.

    Blockchain technology will enable “auditable, transparent, and self-directed data sharing of digitome data.” In fact, “as researchers use the Medable platform, they are able to contribute data to the digitome in exchange for funding and other research resources. Access to the dataset can then be requested by third parties via smart contracts, which utilize self-sovereign digital participant identities to give individual participants the power to consent and be rewarded for sharing the requested research data and/or consideration of a related clinical trial.” The company raised $5 million in funding in February.

    In a detailed blog post, David Houlding, director of Healthcare Privacy and Security at Intel Corp.’s Intel Health and Life Sciences unit and Heather Flannery, CEO of Obesity Prevention, Policy, and Management, Inc., set out to provide best practices and key use cases for how blockchain technology might affect the healthcare ecosystem in the future.

    Layer 0 represents where the world is today — “the majority of healthcare data today is stored within various enterprise system data silos with healthcare providers, payers, pharmaceuticals, life sciences, or business associates/data processors.” This data should be shared in order to improve quality of care and to lower costs.

    Layer 1 represents the next logical step, blockchain, as it enables the sharing of data between healthcare organizations — “Existing healthcare B2B networks have been identified as near-term opportunities for blockchain to add value. These range from clearinghouse networks, health information exchanges, drug and medical device supply chains, provider credentialing networks, clinical data sharing networks and many others.”

    Layer 2 involves smart contracts can be “built upon blockchains and introduce executable code that can trigger on matching blockchain transactions, automate processing, and output results onto the blockchain.” They will enable “more code to be executed directly on blockchains, versus only within healthcare organizations enterprise systems as is done today.”

    As for Layer 3, cryptocurrencies and tokens can then be introduced, as they are built upon blockchains and smart contracts. The article states “cryptocurrencies and tokens may make sense for some healthcare blockchain use cases and enable new commerce and incentive systems. For example, patients may earn cryptocurrency or tokens by participating in clinical research studies using blockchain, and redeem this value to help offset their healthcare costs.”

    And finally, Layer 4 points to artificial intelligence and machine learning, which, for example, “can help analyze various types of scans for heart disease and lung cancer, enabling earlier detection and improving patient care options.”

    Blockchain technology stands to significantly improve the healthcare industry as we know it. Lisk is excited to greatly contribute to the sea of change that this industry and many others are about to experience.
