  Pact: Smart Contracts You Can Take To The Bank Douglas Beardsley
  The revolutionary idea of putting computer programs in a blockchain to create smart contracts has opened up a whole new world of possibilities. But, these programs have very different characteristics from other software. This talk explores these differences, some of the challenges that have been encountered, and then discusses how Kadena is solving these problems with its smart contract language Pact.

  Distributed Trust Design Dr. Johan Pouwelse
  We now have the ability to create trust with software, as shown by Ebay, AirBnB, and Uber. Delft University of Technology is home to the oldest research group creating online trust at scale with real people. A total of 1.8 million people have installed our Tribler software over the years. It offers a Youtube-like experience with Bittorrent support, Tor-like anonymous tunnels, and our own bandwidth token economy. In August 2007 we launched a primitive distributed ledger together with Harvard University for "bandwidth-as-a-currency". It provides an incentive to donate seeding bandwidth or Tor-like relays. We have expanded upon this initial operational system ever since. Our system is based on trust, instead of crypto puzzles. Our IETF standard outlines "Trustchain" in detail. Trust and trustworthy identities are essential. We worked for years on the problem of fake identities and we will go live with the first government-backed self-sovereign identity after the summer. We want to generalize the various isolated profit-driven communities which try to build trust, to form a public utility. Our audacious ambition is to establish a new scientific field, we call Distributed Trust Design. Distributed Trust Design provides a coherent framework to transform mutually non-trusting people into trustworthy online communities of arbitrary size, that have a process for democratic decision-making, the ability to punish those who freeride on the community or are dishonest in order to manage a marketplace, govern a resource sustainably, schedule activities, or achieve a common purpose in general.

  Making Enterprise Blockchain a Reality Joost Volker
  After all the experimentation with blockchain in prior years, are the enterprises ready to go live? What do enterprises need to succeed with blockchain projects, and how is Oracle responding? We’ll share a number of these examples from real world enterprises, and explain how they are re-engineering their business processes to raise the level of trust through the use of permissioned blockchain technology integrated with identity management and role-based access control. We’ll also look at what challenges companies are working to address, and how blockchain technology is evolving to bring greater performance and plug-n-play integration capabilities to meet the needs of the enterprise.

  Managing confidential data on a public blockchain. Draltan Marin
  We present a real-life use case for proxy re-encryption in the context of the Unicorn Bay solution. Unicorn Bay is a blockchain solution for the Asset management industry where we keep track of portfolio management strategies and classic assets trading operations. These are highly strategic information for our clients and as such should remain confidential. Keeping the right balance between a fully decentralized architecture and private data requires a method for encrypting data and having access control on that data. In order to solve this issue we use proxy re-encryption.

  Scaling blockchain in depth Alexander Vlasov
  Scaling a public blockchain has been proven to be a challenge. Now everyone understands the trade off between partial data and processing locality (delegates Proof of Stake consensus) and true distributed participation (Proof of Work). Following a brilliant idea from the original Plasma whitepaper (plasma.io) BANKEX has developed its own implementation that allows to scale an asset transfer transactions to 10k transactions per second, provides customer protection and can resolve disputes automatically through the smart contract. Here an BANKEX we believe that delegation of processing to sibling chains with possibility of dispute resolution on the patent one is a right way to solve processing speed/ distribution trade off in public ledgers

  Bridging the gap between untrusting devs and trust-seeking users Yonatan Sompolinsky
  While Satoshi's achievement in designing a consensus protocol for a totally decentralized system isn't overrated, the setup of total trustlessness imposes severe limitations on its scalability. Protocols which give some authority to recognized nodes are easily more scalable and efficient; yet, this boost in performance comes at the expense of needing to trust these nodes. This trust can take vastly different forms, from trusting a single entity with the integrity of the data, to trusting it with the persistence of the state, to trusting it merely for good performance of the system. This spectrum of trust can potentially bridge the gap between developers who advocate for full decentralization and redundancy of the base platform and product managers who are interested in use cases for ordinary trusting end-users.

  Trust but verify: a missing link between IoT and a trustworthy, computationally verifiable reality Roman Shaposhnik
  Blockchain has fundamentally changed our relationship with trust. At its core, blockchain networks (and their consensus protocols) provided to us a feat of engineering that seemed impossible just a few years ago. A system can now be computationally proven trustworthy as a whole without every individual entity within that system needing to be fully trusted. Still, so far we mostly dealt with blockchain systems rooted in the virtual reality (crypto currencies, digital identities, smart contracts, etc.). This talk will briefly cover: What is a cyber-physical system and why cyber-physical systems are fundamentally different from systems rooted in virtual reality. Why cyber-physical systems require a hybrid approach to building a trustworthy, digitally verifiable "digital twins" of the physical world they are embedded in. An approach, built around using Delegated Proof-of-Stake (DPOS) Consensus blockchains coupled with trustworthy, fully disaggregated software computational enclaves, allowing for the creation of radically different kinds of oracles. The kinds of oracles that can finally provide to be the missing link connecting blockchain and smart contracts to the trustworthy, computationally verifiable reality and all of its rich information sources.

  Keynote I The Whole is Greater than the Sum of its Parts Christopher Ferris
  Hyperledger was formed with the vision of establishing a community where we could bring together the smartest minds to solve the challenges of delivering blockchain technology for the enterprise. Two and a half years later, that vision is being realized. Hyperledger's "greenhouse" is not only incubating new technologies, but is now entering into the collaboration and consolidation phase, and out of this is emerging some important new innovation.

  Beyond DAPPS, building an application protocol Christopher Georgen
  When Topl began development in early 2017, Chris and his team set out on a truly unique course for the blockchain space. Instead of trying to build the next Ethereum, a single blockchain meant to run a myriad of decentralized applications (DAPPS) or simply building a DAPP on top of someone else's blockchain, Topl set out to build one of the very few application specific blockchains. The Topl blockchain incorporates a significant but finite set of features, including prediction markets, smart contracts, supply chain integration, and identity management, all in support of a single process, socially-responsible investment into developing countries. In this talk, Chris and Topl's CTO, Jim Aman, will detail Topl's approach to the building its own application-specific blockchain, covering both the benefits and drawbacks of such a strategy.

  Workshop 3 Blockchain in Scala

  Description

  In this workshop, Nick Edmonds, CTO and Co-Founder of Topl, will introduce you to their Edda framework. Designed to be deployed as single-use public, permissionless blockchains, Edda incorporates the first implementation of the Ouroboros Genesis consensus algorithm, allows for domain specific smart contracts, and supports complex actor types and attributes. Leveraging the JVM for its cross-platform capabilities along with the built-in JavaScript runtime environment the Nashorn Engine, this framework takes advantage of the concise structure of Scala in combination with the ability to write smart contracts in JavaScript, one of the most popular programming languages in the world. A blockchain created with the Edda framework can be deployed on nearly every device, with a smart contract language most developers are already familiar with. Scala’s Akka actor model provides for a highly concurrent and distributed system, important for decentralization and speed when settling transactions within a distributed network. pattern matching, case classes, and strong typing system within Scala allow the Edda framework to easily create new tokens and digitize assets onto the blockchain. The immutability of functional programming in Scala lends itself well to abstracting data structures used to build blockchains. Abstracting core components into easy to reason models allows multiple developers or teams to quickly add new features within the framework. Through this session, you will become familiar with the motivations behind a Scala and functional-first blockchain implementation, the architecture of a single-use blockchain, and the steps needed to deploy your own specialized chain.
