What is BlockSplit?

BlockSplit is a blockchain community conference organised to grow the global blockchain ecosystem.

It provided experienced members with a stage for sharing knowledge and onboarding new talents into the community. Our hands-on development workshops, development- and business-oriented presentations accelerated the growth of blockchain usage and acceptance in businesses and society.

The conference set the stage in Split, Croatia, on 27th and 28th of April 2018. The first day was reserved for full-day hands-on development workshops. On the second day, the conference is split into development oriented and business oriented track.

    8:00 - 9:00
    Workshops registration & coffee

    Each workshop starts in its own dedicated room at 9:00 am. Attendees should be there in time to set up their working stations. Information about the room will be provided on check-in. These full-day hands-on development workshops have the number of seats limited to 20 in order to maintain the quality. You can attend only one workshop. Click on the workshop name to see more details. Please come earlier to set up in time.

    Decentralized Autonomous Organizations or DAOs for short are one of the key transformative aspects of programmable blockchains. They’ve been given a bad rep because of the DAO hack in summer of 2016, but some of the most interesting projects in the crypto space are structured as DAOs. You will learn how DAOs work, how can you participate in a DAO and how to build one yourself. Please come earlier to set up in time.

    Stack: Solidity, Ethereum Rinkeby testnet, Metamask, web3.js

    Mislav Javor

    ICOs are fundraising processes that issue “shares” of a project in the form of a token to early adopters and enthusiasts in return for funding the project and getting it off the ground. We’ll run our own blockchain, build an ICO from scratch, deploy our own token and get it verified, and run a crowdfunding process. By the end of the workshop, you’ll have built a non-traditional ICO, fully deployed on the Ethereum testnet with usable tokens. Please come earlier to set up in time.

    Stack: Basic code editor (vscode, sublime text, webstorm, etc).

    Bruno Škvorc

    Centralized exchanges are great if you don’t mind the risk of losing your coins in a theft, getting expropriated by the government, locked out of your funds during a downtime or exposing your identity. Many believe these problems are the reason why decentralized exchanges or DEXes are the future. Exchanges are very profitable businesses, and here we will learn basics of building exchanges of future. Please come earlier to set up in time.

    Sulejman Sarajlija

    Scaling Ethereum can be done on many ways, one of them is via state channels. Conducting micro-transactions off-chain in trustless manner helps us to preserve blockchain’s security, but with increased efficiency. We will work on payment channel implementation in solidity, deploy it to testnet network, wire everything with web3 and make it usable in real world. Please come earlier to set up in time.

    Admir Šabanović

    Barbecue Beach Party (BBBQ) will be held on Hotel Split beach. Because of limited capacity it is exclusively available to attendees of workshops, speakers and sponsors only.

    We will expand the concept of business model canvas used by various product owners and integrate it into the blockchain ecosystem. The idea of this workshop is to give attendants a model of implementing blockchain technology into their own or their clients existing IT and Business systems with validating and locating pros and cons of such endeavor.

    Luka Klancir

    During this workshop we will introduce the basis of game theory. We will see how this applies to Blockchain systems. There will be participative experiments where participants gain or lose tokens depending of their decisions and decisions of others. Participants will compute equilibriums of various games. We will also cover mechanism design asking participants to design rules of the game.

    Open source software projects, the communities around them, and how to incentivize open source collaboration in now and in the future!

    This presentation will be an overview of some of the ways in which you can test Ethereum smart contracts. It will cover setting up a local chain for end-to-end testing, writing unit and integration tests both in Javascript and Solidity. Also briefly covered will be a novel approach to testing smart contracts using SPIN Model Checker.

    Writing correct smart contract is hard (a recent study estimated that 3% of Ethereum contracts in the wild have some sort of security vulnerability; we all know of the DAO and Parity exploits, …). There are two main reasons for this. First and foremost developing for the blockchain is quite different than what most programmers are used to. The level of concurrency is far beyond our (von Neumann) intuition and mental models. And you can’t stop and inspect running code like you can in other systems. Taken together blockchain is closer to a physical/living system than conventional software — a fact not reflected in the tools available. Compared to other domains our tooling and programming languages are somewhere between rudimentary and bad; and a far cry from where they would need to be to augment developers and help make programming for the blockchain less alien and less error prone. In this talk we will first unpack what makes programming for the blockchain hard, and what are the most common types of vulnerabilities and their causes. Then we will look at the state of art programming language research in correctness proving and programming massively concurrent systems; and how these can be applied to programming smart contracts; revisit some technologies from the past that didn’t get traction at the time, but are nevertheless worth studying; and finishing off by trying to imagine how programming for the blockchain should, and perhaps one day will, look like.

    The advent of cryptocurrencies has invited us to reexamine the nature of money. With tools capable of rapidly designing new monetary systems, we no longer have to accept fiat currency as a hegemonic measure of value. Circles is a cryptocurrency whose only form of issuance is as a universal basic income to all. This makes it a trickle-up monetary system where value creation is decentralized and transactions are facilitated through a web of trust.

    Martin Lundfall

    In this keynote we will speak about how current business model design techniques can be used for the blockchain. Design thinking, business model generation techniques, and other customer centered methodologies would be very helpful to start building blockchain applications that solve human needs, contributing to the create a wider, stronger business ecosystem.
