0x: an open protocol for trustless, low friction exchange of ERC20 tokens

In the two years that have passed since the Ethereum blockchain’s genesis block, numerous decentralized applications (dApps) have created Ethereum smart contracts for peer-to-peer exchange. Rapid iteration and a lack of best practices have left the blockchain scattered with proprietary and application-specific implementations. As a result, end users are exposed to numerous smart contracts of varying quality and security, with unique configuration processes and learning curves, all of which implement the same functionality. This approach imposes unnecessary costs on the network by fragmenting end users according to the particular dApp each user happens to be using, destroying valuable network effects around liquidity. We present 0x: an open protocol and shared settlement layer for trustless, low friction exchange of ERC20 tokens.

1protocol – Virtual Ethereum Workers

1protocol is a platform that enables users with idle tokens and machines with idle computing power to collaboratively perform work for staking protocols on Ethereum such as Casper. Using 1protocol, users can trustlessly earn interest on their token holdings and machines can perform work for staking protocols without putting up stake.

A Fast and Scalable Blockchain for Enterprise Users

Almost every bank and major financial institution inChina as well as across the world is eager to revamp their computing infrastructure through blockchain. What a blockchain designed for them should look like? Is it enough to replace PoW with PBFT? What else can we do to leverage the resources enterprise users have? You will find the answers in CITA.

AION: Connecting Blockchains over a Common Fabric

Mainstream adoption of blockchain technology in the enterprise ecosystem has been impeded due to inherent limitations of scaling individual blockchain networks. We are introducing AION – a multi-tiered blockchain system designed to address some of these core challenges. Core to our hypothesis is the idea that many blockchains will be created to solve unique business challenges, within unique industries. As such, the AION Network is designed to support many custom blockchain architectures, while providing a trustless mechanism for cross-chain interoperability. By utilizing our concept of “bridges”, this multi-tiered blockchain model will allow the creation of layers of connecting blockchain networks that are able to communicate and transact among each other.

Babbage: A mechanical smart contract language

In textual programming languages it is often almost impossible to see how different parts interact and fit together. Babbage is a visual programming language that consists of simple mechanical parts that aims to be understandable even by untrained people. Since interacting components have to be physically close, modularity is already guaranteed by design. The goal of Babbage is not to make it easy to create smart contracts, but to make it possible to create smart contracts whose functionality is easy to explain and understand.

Blockchain for Humanitarian Assistance

In the past few years the humanitarian community has been increasingly adopting Cash-Based Transfers as the means to provide assistance to beneficiaries. With CBT instead of, for example, receiving in-kind food, beneficiaries receive the means to purchase their own food in the form of pre-paid bank cards, mobile money, vouchers, and bank notes. In order to enable CBT, organizations rely on financial service intermediaries that bring with them costs, risks, reduced beneficiary privacy, accountability concerns, and delays. WFP is piloting an Ethereum based blockchain project called ‘Building Blocks’ to address these issues and reduce duplication and fragmentation in the system by fostering interagency collaboration around a neutral blockchain platform.

Building an Ethereum assisted Decentralized Data Marketplace Breakout

Data has become a valuable digital currency in its own right over the past decade, but despite its utility, it remains consolidated at the hands of a few large organizations. We propose a new protocol layer for creating an open-access data marketplace. The protocol is decentralized, and allows anyone to publish data in the system in return for incentives. We will discuss the hybrid architecture of the protocol, combining Ethereum smart-contracts for managing data access and subscription, alongside an off-chain network for storing and transmitting the data. Finally, we will introduce Catalyst – the first application to make use of a decentralized marketplace of crypto-data.

Building Consumer Facing Interfaces for Trust in Supply Chains

Provenance is building a platform to make consumer product supply chains more transparent. Taking advantage of Ethereum and IPFS, we’ve been iterating through a number of pilots in different industries, from organic bacon to fair-trade coconuts to enable a simple shared and trusted way to share the proven claims behind our products e.g. organic or proof of payment of fair wages, and link that to the flow of batches of product. Throughout this journey, we have learnt a lot about industry needs, working with both small and large retailers and brands. We’ve also forged partnerships with sustainability standards e.g Soil Association organic and other data systems that we can connect to enable verification of claims and inputs for our Ethereum based app e.g. Sourcemap. User centred design is core to the work at Provenance – exploring how we can make blockchain backed data appear differently on the frontend and provide accessible links to inspect the chain. As a social enterprise largely built through grant funding and with the support of academia we are keen to share our learnings with the developer community and gauge interest in forming a group around the development of blockchain backed interfaces for trusted data sets.

Challenges Ahead for Smart Contracts

Ethereum has unleashed the power of smart contracts by creating a massively distributed, resilient, and replicated computing platform. In this talk, I will discuss the three challenges I see ahead for Ethereum, go over known techniques for addressing them, and will identify the future work that needs to be done because of the unique challenges faced by the Ethereum platform. First, we’ll talk about scale, touch upon known techniques for scaling on- and off-chain. Next, we’ll talk about program verification, what it can do, and why it is not the panacea that many people make out to be. In particular, I’ll talk about the kinds of smart contract properties that we know how to ascertain, versus the kinds of smart contract properties that we would ideally like to verify, and discuss the gap between the two. Finally, I’ll talk about the next frontier involving private data and private computation on a public blockchain, a combination thought to be impossible by some, and describe how we can achieve it with the help of secure hardware.

Dai Stablecoin

The process of developing the Dai Stablecoin System has matured significantly over the course of the last year. We innovated in the Ethereum community by being the first project to release a well-defined reference implementation, written in Haskell, for our proposed system. This effort has helped with the simplification of the system’s design, increased project efficiency, and has attracted the attention of formal verificiation specialists who now want to focus on Maker. It is becoming more and more likely that Maker will be the first non-trivial decentralized application to be formally verified before launch. In this proposed presentation, I would like to talk about the usefulness of rigorous specification and external reference implementations for the benefit of other Ethereum projects.

Data is the Missing Link

Thomson Reuters distributes 2.5m financial instrument price updates per second; data that is used to price over $3tn in assets each day. Blockchains rely on trusted sources of data and trusted mechanisms for data delivery, without which many of the use cases for smart contracts cannot be realized. This presentation will cover a range of active use cases that include Thomson Reuters data on people, organizations and tradable instruments being applied within financial services as well as other industries such as commodities and energy. It will introduce the complexities of having data as part of your value proposition, and look at current and future approaches for data commercialization on blockchains and DLTs. All of these key learnings have been developed through the use of the Thomson Reuters oracle, BlockOne IQ, that was designed specifically for Ethereum.

KEVM: Overview and Progress Report

Since the IC3 Crypto Boot Camp, we have been extending the KEVM semantics in several directions. At the time, we only supported the VMTests from the Ethereum Test Suite, it was somewhat difficult to write properties and proofs about programs in EVM, and EVM-PRIME was a simple demonstrative toy language. This session will cover the progress so far in addressing these issues, as well as our goals and intentions for the semantics moving forward. In particular, we are focused on providing tools to ease the process of writing and proving specifications about programs written in high-level languages. Everett Hildenbrandt is a CS PhD student at University of Illinois Urbana-Champaign studying formal methods and programming languages. He is focused on improving the scalability of symbolic reasoning for applications in both distributed and physical systems. In the context of blockchain systems, he is interested in formalizing the semantics of both the underlying languages used and the consensus protocols. To this end, he recently led the KEVM project which developed an executable mathematical model of the EVM in the K Framework.

Mind the Gap: Application-driven evaluation of Smart Contract languages

How can we quantify the expressiveness of smart contract programming languages? In this talk I’ll present research conducted over the past two years that answers this question with an application driven approach. We take several well-known applications as case studies (a random coin flipping gadget, fair off-chain multiparty computations, and payment channel networks), and attempt to implement them in both Bitcoin script (UTXO-based) and in Ethereum (contract-based). In each setting, we find that the UTXO-based framework requires additional asymptotic overhead compared to Ethereum (either time, computing power, or locked-up collateral). These case studies can therefore serve as a benchmark suite for evaluating new languages as well.

Pluggable crypto for Ethereum nodes: Masterchain experience

Ethereum has a few subsystems which use cryptography in their core functionality: 1. Transaction processing system, 2. P2P node communication, 3. EVM (Ethereum Virtual Machine), 4. Mining. So far all these systems use only one crypto library but they use it in different ways. We have developed an extra crypto-layer, which makes crypto to work as an additional abstract layer. The extra-crypto layer is completely transparent for all ethereum logic. It allows to switch crypto-algorithms to use in Ethereum.

Scalable Onchain Verification for Authenticated Data Feeds and Offchain Computations

Ethereum smart contracts live like in a walled garden and they cannot fetch offchain data by themselves. One approach to securely feed offchain data into smart contracts is to provide attestation-backed data authenticity proofs that anybody can verify to ensure that the data-transport-layer is safe. By leveraging some new techniques, it is possible to do an effective onchain verification: the smart contract receiving the data can easily verify its authenticity onchain at a negligible cost and with a minimum amount of data.

Scalable Secure Scuttlebutt

secure-scuttlebutt is a secure gossip protocol with efficient data replication. This talk is about how efficient that data replication is. In the blockchain world, the first goal is global consensus – secure scuttlebutt throws this out the window, and goes for eventual consistency and local consensus, and that frees us up to get really great efficiency. Fortunately there are many useful and important things you can build without global consensus (for example, social networks, and things strapped onto social networks) and these usually benefit greatly from efficiency.

Secure Decentralized Oracles: Applying Intel SGX and TownCrier to external data, payments and off-chain computation

We will cover the need for secure and maximally decentralized oracles for Ethereum smart contracts. The focus of the presentation will be on how allowing data providers, payment providers, and various API-based services to be accessed by Ethereum smart contracts through a decentralized oracle network can greatly expand functionality, while maintaining the key security guarantees of smart contracts. We’ll focus on how TownCrier’s approach to implementing Intel SGX enables third party oracles to be provably secure, as is already being done on production using the currently live TownCrier implementation. We’ll also look at how oracle operations and off-chain computation can be written in solidity to be run entirely in an SGX Enclave, allowing provable off-chain computation and retrieval of external resources. Smart contracts need to retain a high level of security in both the network they run on, and the inputs/outputs they rely on, we aim to show how decentralized oracle networks, TownCrier’s approach to using Intel SGX for secure external access , and off-chain computation using solidity in Intel SGX can together allow smart contracts to remain secure as they access key resources outside the Ethereum network.

Securify: Not Your Grandma’s Smart Contract Verification

We present Securify (www.securify.ch), the first push-button security auditing tool for Ethereum smart contracts that is fully automated, easily extensible to new security vulnerabilities, and provides strong security guarantees. The core technical idea behind Securify is to soundly extract deep semantic information from the smart contract using automated abstract reasoning. This information is then used to ensure the absence of critical security vulnerabilities, such as reentrant calls, unprivileged storage accesses, and many others. Securify precisely analyzes real-world smart contracts within seconds, and handles any language that compiles to Ethereum bytecode.

The Blockchain Virus: Can a blockchain pay to replicate?

Full nodes provide many services to a cryptocurrency network: data forward, blockchain storage and retrieval, and some privacy and DoS protection. But as the resources consumed by a blockchain network grows, so is the node cost. Full nodes are usually altruistic, they take resources from their peers and they give back. But there is no immediate benefit to give back. This problem, which can lead to a tragedy of the commons, was early identified in the “Red Balloons” paper. Some solutions involve using master-nodes, leading to centralization risks. In this talk we’ll show how to create a fully decentralized system for rewarding full nodes that is fully autonomous, and controlled by a smart-contract.

The Colony Reputation Protocol: a verifiable, scalable reputation system

Colony relies on a broad reputation system to facilitate governance and decision making. The reputation system we are building is far more complex than anything that could be done in a smart contract alone. Instead the system overcomes scalability/gas cost limitations with off-chain computation of the reputation scores which are provable on-chain to the contract. In this talk we will describe how this off-chain calculation with on-chain verifiability is designed and game theoretically secured. We will also describe what kind of actions in a Colony will earn you reputation, and how reputation is used in our collective decision making process.

The Open Vote Network: Decentralised Internet Voting as a Smart Contract

The Open Vote Network (OV-net) is a self-tallying (and self-enforcing) e-voting protocol i.e. there are no tallying authorities – anyone can count the votes. It is also the first extensive cryptographic protocol to be implemented as a smart contract (i.e. zero knowledge proofs) that *can work* on Ethereum’s official network today. I’d like to present the protocol, the technical difficulties I faced while building it (and the gas costs before/after hardfork if feasible), and the beauty of combining both cryptographic protocols and smart contracts.

Using Ethereum for Secure Decentralized Optimization

We demonstrate how complicated optimization problems can be solved by combining decentralized optimization algorithms with an aggregation step in a smart contract. Using tools from convex optimization, we decompose difficult problems into a set of subproblems with can be computed off-blockchain, finally reaching consensus on the global optimum by passing message with the on-blockchain aggregation step. We present an example of applying this approach to optimizing power dispatch on an electricity grid, but the approach can also be used to solve other problems in machine learning, coordinating robotic agents, or coordinating economic systems.
