Coupled with a pure on-chain design, the DutchX doubles a price oracle and is built to enable users, bots, as well as other smart contracts to exchange tokens: no strategy for participation is needed. Trading on the DutchX, users benefit from getting a fair price for their tokens through the bundling of liquidity. Additionally, all fees levied in the exchange remain in the exchange — no value is extracted! Any decentralized application in need of exchanging tokens or integrating a price feed can make use of the DutchX. The possibilities are tremendous! The DutchX will soon be governed by a DAO. Check out https://slow.trade - a graphical user interface that lets you interact with the DutchX. Listen up and take note: During the workshop, we will first introduce the DutchX auction mechanisms and token design. We will also present a few potential DutchX use cases for developers to build on. We will then give you a hands-on walk through of the  integration steps Bring your laptop with Node JS, Docker installed and make sure to top up your Rinkeby Eth. We are looking forward to building a dApp on top of the DutchX with you. d.fusion — A Scalable, Fair Exchange Conventional centralized exchange mechanisms are innately flawed. Issues with fragmented liquidity, and arbitrage trading, and front-running have clearly demonstrated that centralized exchange mechanisms do not meet the needs of a decentralized future. Self-proclaimed ‘decentralized exchanges’ exist today, but the vast majority are solely non-custodial, that is, they don’t hold customers’ funds. Introducing d.fusion, a fully decentralized exchange that looks past these limitations. D.fusion is arbitrage-free by design, doesn’t allow systematic front-running, and can be partly operated by all participants in the network. Our amazing speakers and mentors:  Christiane Ernst, Product Manager - DutchX At Gnosis, Chris is responsible for the DutchX, an open, decentralised exchange protocol for ERC20 tokens based on the Dutch auction principle. An economist by training, Chris previously specialised in auction design. Her fields of interest also include game theory and incentive mechanisms. She strongly believes that blockchain technology will revolutionise human interaction by eliminating middlemen, and thereby decreasing transactional inefficiencies. She is a certified Swiss Tax Expert and has extensive experience in corporate tax accounting as well as transfer pricing. Felix Leupold, Software Engineer - d.fusion Felix is a software engineer with a strong passion for systems design and test driven development. While receiving his Master degree at Hasso Plattner Institute, he temporarily worked for multiple large tech companies, including Google and Facebook and participated in a global Design Thinking class at Stanford University. After graduating he joined Facebook full-time, where he built end-to-end encrypted communication for Messenger and later worked on realtime-infrastructure. At Gnosis he is building a decentralised exchange, focussing on zero knowledge proofs and off-chain scalability solutions. Angel Rodriguez, Tech Lead - DutchX Angel is a full stack software engineer at Gnosis with a passion for decentralisation. He is particularly interested in building new mechanisms to facilitate the exchange of information and value David Sato, Full Stack Engineer - DutchX David is a Software Engineer and Economist by training.

Work on Blockchain are pleased to invite you to attend our #2nd edition of our intensive one-day blockchain developer workshop focusing on Ethereum internals with Nethermind in the beautiful King’s College London Strand campus on Saturday 20th of October, 2018. We were over subscribed from our #1st advanced workshop where we had 50 registrations. Don’t wait until last minute, we have limited space so sign up early! Sponsors required! In order to keep running this workshop for free, we are looking for sponsors. Please inquire by sending an email to antonio@theblockchainconnector.com  Ethereum internal workshop with Nethermind: In this workshop you will learn how Ethereum works under the hood. If you ever wondered how EVM executes smart contracts code or how the Ethereum account data is stored in the database then this workshop is for you. We will cover a broad range of topics including block and transaction data, signatures, mining with ethash, devp2p (network protocol) and private networks. You will learn how to setup a private Ethereum network using Nethermind to run network nodes. Nethermind is an open source Ethereum client which you can use to setup blockchain in your organization. We are building a community of .NET Core developers building enterprise tools for Ethereum. Requirements: To be able to participate you will need to bring a laptop (or desktop if you prefer) with the newest version of IDE (JetBrains Rider or Visual Studio) and .NET Core 2.1 SDK installed. You can use Ubuntu, Windows or Mac OS You are expected to be fluent (or willing to be fluent) in C#. If you have only worked with .NET Framework before and not with .NET Core then do not worry – the platform is new but tools and libraries are mostly the same. This is an advanced workshop, hence you should already have a working knowledge of Ethereum and blockchain technology in general.   What will you learn? During the workshop you will setup your own private Ethereum network (and choose your own consensus protocol). You will write a smart contract in byte code and analyse its execution on your own network.   What next? If after workshop you are hungry for more you can contribute to the open source Nethermind project on github. Nethermind is still under development and there are parts of Ethereum protocol that still need to be looked at. This is a great opportunity to get a deep understanding of blockchain, Ethereum and / or .NET Core.   Would you like to experiment with Nethermind ahead of the workshop or need help installing the tools? Please drop us a line on contact@workonblockchain.com   Do not miss this FREE one-day blockchain developer workshop. This type of workshop would normally cost over £1000. We will end the day by going for drinks and dinner with the class from 18:00 near the venue.  Stay in the loop! If you’d like to stay in the loop with all the updates we are constantly shipping, go ahead and subscribe for our private mailing list at Work on Blockchain sign up page. We will be hosting multiple hackathons, coding workshops and regular technical deep dives. Stay tuned!

After the workshop, we hope our students will continue to code and explore the Ethereum platform, and in good time, we hope our students will have the opportunity to work professionally in the blockchain space. With this in mind, to help our students succeed, everyone have up to a month to ask further questions in relation to Ethereum, Solidity, Smart Contracts, Security, Privacy, Scalability etc. We have further coding sessions for our students to work on with our guidance during the one month support. Furthermore, we encourage our students to work on a personal project or form a team to create a project. Once the project is complete, we will offer our services free of charge to audit the code and provide guidance where necessary.  Right to cancel our workshop If we don't reach the minimum number of students for our workshop, we have the right to cancel and reschedule the date. We have a great line up of internationally recognised experts that will help you break into the Blockchain space.

Nick Johnson Nick Johnson is a Senior Software Engineer and has been working in the software engineering space for the past 16 years. Nick is currently working as a Software Engineer for the Ethereum Foundation and prior to this, he worked at Google for a number of years. He brings with him a wealth of knowledge and expertise in Solidity that he loves to share and will be teaching how to write and develop smart contracts during the hands-on development session, and will give students the opportunity to ask questions in relation to the Ethereum platform. Laurence Kirk After a successful career writing low latency financial applications in the City of London, Laurence was captivated by the potential of Blockchain Technology, and in particular smart contracts. Two years ago, Laurence moved to Oxford and set up Extropy.io, a consultancy working with start-ups in the UK and overseas, developing applications on the Ethereum platform. He brings with him a wealth of real world experience that he loves to share with those new to this area. Laurence hold a Physics degree from Durham University, and currently taking his MSc in Software Engineering at Oxford University. In addition to giving talks, mentoring at hackathons, and running groups about Blockchain Technology, Laurence also organise Artificial Intelligence and Data Science groups in Oxford. During the workshop, Laurence will be teaching Solidity (an object-oriented programming language for writing smart contracts) from the simplest smart contract up to interacting with a web application. The focus is very much the practical techniques that are needed when developing on Ethereum. The sessions will be very hands on, encouraging students to practice and explore Ethereum and raise any questions students might have regarding the Ethereum platform. Matthew Di Ferrante Matthew is a Software Engineer with a passion for Information Security, Cryptography, and Distributed Networks. He has worked in many different areas, from hardware, embedded and kernel programming, to data mining, analytics, and network / systems programming. He first started learning programming at 12 years old, and is completely self taught, both on the practical side of programming, and on the theoretical side of computer science, mathematics, and cryptography. Matthew was first exposed to Bitcoin in late 2010 due to his interest in information security, as Bitcoin was first mainly used on darknets/Silk Road, and got fully involved in the Blockchain space around the time Ethereum started to exist - beginning his foray while living with Vitalik Buterin and long time friend Vlad Zamfir (Creator of Ethereum's Casper Protocol) in London for a few months. Matthew currently works as a Technical Lead at Clearmatics developing Blockchain Technology for financial use cases, a member of the Ethereum Foundation Security Team and FounderlLead auditor at Zero Knowledge Labs focusing on smart contracts security auditing. In his free time, Matthew works on personal hardware projects, gives Information Security and Blockchain related talks at various events, and organise one of the largest monthly Information Security events in the North-West.

TALK TITLE: Reasoning about Trace Vulnerabilities in Ethereum Smart Contracts KEYWORDS: Ethereum, Smart Contracts, Program Analysis, Symbolic Execution ABSTRACT: Smart contracts — stateful executable objects hosted on blockchains like Ethereum — carry billions of dollars worth of coins and cannot be updated once deployed. Im my talk, I will present a systematic characterisation of a new class of trace vulnerabilities, which result from analysing multiple invocations of a contract over its lifetime. We will discuss three example properties of such trace vulnerabilities: finding contracts that either lock funds indefinitely, leak them carelessly to arbitraryusers, or can be killed by anyone. I will then describe the design and implementation of Maian, the first tool for precisely specifying and reasoning about trace properties, which employs inter-procedural symbolic analysis and concrete validator for exhibiting real exploits. From nearly one million contracts in Ethereum blockchain, Maian flagged 34,200 (2,365 distinct) contracts as vulnerable, in 10 seconds per contract. On a subset of 3,759 contracts sampled for concrete validation and manual analysis, we reproduced real exploits at a true positive rate of 89%, yielding exploits for 3,686 contracts. Amongst others, Maian also found exploits for the infamous Parity bug that indirectly locked 200 million dollars worth in Ether. This project is a joint work with Ivica Nikolić, Aashish Kolluri, Prateek Saxena, and Aquinas Hobor. SPEAKER: Ilya Sergey SHORT BIO: Dr Ilya Sergey does research in the area of programming languages, program analysis, and formal verification. In recent years, Ilya has mainly been concerned with developing scalable methods for building trustworthy concurrent and distributed software, but his earlier work was advancing the state of the art in static analysis for higher-order languages and programming language design.
