Competition Rules

For the full list of rules for the Innovation Blockchain Hackathon 2019 click on the button below.


Join the hackathon on blockchain and distributed ledger technologies (DLTs) and to respond to the following core challenges:

  • New businesses: How do blockchain/DLTs challenge and transform the existing infrastructures and institutions? What new and unexpected, social, technical and business models they bring about in areas such as offer for managing data and, assets, global trade, etc.?

  • Legacy technologies and procedures: How to integrate blockchain/DLTs with existing procedural, operational, social and technical infrastructures? Can it improve the efficiency and transparency of business and governance?

  • Emerging technologies: How to integrate blockchain/DLTs with various branches and methods of AI, machine learning? How to use existing and new sources of data (IoTs, satellites, biochips etc.)?  

  • Code-enforced contracts: How can the self-executing function of blockchains/DLTs facilitate, verify, and enforce the negotiation or performance of agreements?

  • Blockchain for good: how to use the emerging technology in areas such as fighting the climate change or supporting human rights? How can blockchain/ DLT enhance consumer confidence and support more ethical and sustainable business practices?

  • Monetizing and protecting creativity, art and design: How can immutability and integration of blockchain/ DLTs help protect intellectual property? Can we use it to establish new ways of intellectual creation and dissemination?  

  • Can we create blockchains that care for human rights? Can we design ethical blockchains that fight slavery or improve climate change?    

  • What are the possibilities and limits of automation and governance over the so called “smart contracts”? How to support regulations and standards over blockchain/DLTs, improve consumer confidence and support more ethical and sustainable business practices?  

  • What is the future of creativity, art and design over blockchain/DLTs? What are some reflective and critical uses of such technologies, but also “white/black hat” misuses of such technologies?

14:00 – Participants registration

15:00 – Welcome by organisers

15:30 – Building the teams and pitching your idea

16:00 – Hacking time


A series of expert workshops will be held in the course ofJanuary and February with the purpose of preparing participants to take part in the hackathon. We will explain how Blockchain Fabric works, the legal obstacles that your innovative ideas may encounter and what is possible to build on blockchain in the current business conditions.


WS 2: Design Thinking - Validate your idea

Whenever we design a solution for users, we should use methodologies around human-centered-design. One of the proven business-ready methodologies from this area is Enterprise Design Thinking that was developed and is used by IBM. In the upcoming workshop you will get real hands-on experience of these practices. The attendees will choose if they prefer to get a model overview of the different artefacts used in Enterprise Design Thinking or if they want to build their own solution leveraging chatbot technology.


  • Understanding the user

  • Defining Persona

  • Creating an empathy map

  • Defining of scenario and needs

  • Playback

  • Creating and prioritizing Blockchain ideas/Questionstorming

Where: IBM Czech Republic, Prague

When: 17th January  2019, 10:00 - 15:00

Who: David Enc (IBM), Jan Louda (IBM), Angelika Dudová (IBM)

WS 1: Introduction to Blockchain technology with reals examples of how to build blockchain network 

Introduction to Hyperledger Fabric and understanding how it can be used in Enterprise Solutions. Another part is introduction to Hyperledger Composer which is used as development toolset and framework to make developing Blockchain applications easier.

Thanks to Composer is possibly create quickly model a simple to business network. At workshop you will define your own business network model, transactions and assets. You will create a simple contract and deploy it to a local network Fabric. Then you will test your model and view the results in a viewer of the Blockchain. Some Java script knowledge is a benefit but not required.

Where: Hub Hub, Prague

When: 10th January 2019, 17:00 - 20:00

Who: Mirek Iwachow (IBM)

Duration: approx. 2-3 hours

WS 3: Blockchain – Blockchain Legislation and New Business Models

Distributed ledger is still an emerging technology, therefore business models and services based on DLT may bump into legal obstacles. They may prove to be illegal under specific national legislations, or fall into a gray zone of missing laws, which leads to legal uncertainty discouraging investors. When designing a DLT based project it is therefore necessary to check for potential legal hurdles. The workshop will present current developments in Blockchain related regulation, with focus on potential problems in finance, transportation and logistics, and public sphere.

Where: Business Link, Prague

When: 23th January 2019, 17:00 - 20:00

Registration to presentation

Registration for those who just want to come to see the presentation of the project but do not want to participate in hackathon, challenges and competitions.


Hyperledger Fabric

Hyperledger Fabric is a permissioned blockchain infrastructure, originally contributed by IBM and Digital Asset, providing a modular architecture with a delineation of roles between the nodes in the infrastructure, execution of Smart Contracts (called "chaincode" in Fabric) and configurable consensus and membership services. A Fabric Network comprises "Peer nodes", which execute chaincode, access ledger data, endorse transactions and interface with applications. "Orderer nodes" which ensure the consistency of the blockchain and deliver the endorsed transactions to the peers of the network, and MSP services, generally implemented as a Certificate Authority, managing X.509 certificates which are used to authenticate member identity and roles.

Fabric is primarily aimed at integration projects, in which a Distributed Ledger Technology (DLT) is required, offering no user-facing services other than an SDK for Node.js, Java and Go.

Fabric supports chaincode in Go and JavaScript (via Hyperledger Composer, or natively since v1.1) out-of-the-box, and other languages such as Java by installing appropriate modules. It is therefore potentially more flexible than competitors that only support a closed Smart Contract language.


Hyperledger Composer

Hyperledger Composer is a set of collaboration tools for building blockchain business networks that make it simple and fast for business owners and developers to create smart contracts and blockchain applications to solve business problems. Built with JavaScript, leveraging modern tools including node.js, npm, CLI and popular editors, Composer offers business-centric abstractions as well as sample apps with easy to test devops processes to create robust blockchain solutions that drive alignment across business requirements with technical development.

Blockchain package management tooling contributed by IBM. Composer is a user-facing rapid prototyping tooling, running on top of Hyperledger Fabric, which allows the easy management of Assets (data stored on the blockchain), Participants (identity management, or member services) and Transactions (Chaincode, a.k.a. Smart Contracts, which operate on Assets on the behalf of a Participant). The resulting application can be exported as a package (a BNA file) which may be executed on a Hyperledger Fabric instance, with the support of a Node.js application (based on the Loopback application framework) and provide a REST interface to external applications.

Composer provides a GUI user interface "Playground" for the creation of applications and therefore represents an excellent starting point for Proof of Concept work.


Hyperledger Explorer

Hyperledger Explorer is a blockchain module and one of the Hyperledger projects hosted by The Linux Foundation. Designed to create a user-friendly Web application, Hyperledger Explorer can view, invoke, deploy or query blocks, transactions and associated data, network information (name, status, list of nodes), chain codes and transaction families, as well as any other relevant information stored in the ledger. Hyperledger Explorer was initially contributed by IBM, Intel and DTCC.
