Panel

Improving the Ethereum Virtual Machine (EVM 1.0, 1.5, 2.0)

This panel will consist of experts with deep experience designing and building both the current iteration of the Ethereum Virtual Machine, EVM 1.0, as well as various candidates for future virtual machines including EVM 1.5 (several improvements to the existing EVM) and Ewasm (a reimagining of the Ethereum Virtual Machine built using industry-standard WebAssembly technology). These experts will discuss the history and current state of EVM 1.0, the various improvement proposals that are on the table, and the various initiatives underway today. It will also touch upon harder, more controversial questions regarding the EVM 1.5 and EVM 2.0 (Ewasm) proposals. The panel will give audience members an opportunity to learn about how and why Ethereum and its smart contracts work the way they do today, to ask questions of the experts behind this design, and to participate in the conversation about the future of Ethereum--both the low-level virtual machine and the stack of developer tooling (such as Solidity) built on top of it.

Introducing Pantheon, a Mainnet Java Client - Demo & Roadmap

This will be the launch of Pantheon, a Java client built for mainnet with an eye for meeting enterprise requirements. Having multiple, performant clients is important to the long-term viability of the Ethereum ecosystem, and enterprise adoption will draw greater resources. This will be a demo of the new client with a walk-through of our roadmap. By introducing a client in Java and building it open source, we’re hoping to draw in the massive Java community into the Ethereum ecosystem, support research and innovation led by the Ethereum Foundation, and add extensions to meet enterprise needs on privacy, permissioning, and others. We will also talk about some of our research efforts on top of Pantheon.

Nethermind - .NET Core Ethereum Client

If you are familiar with .NET and new to Ethereum programming, this workshop will teach you how to integrate .net applications or new dapps with Ethereum smart contracts using Nethereum. This programming session will guide through the creation of a standard token (ERC20 smartcontract) as well as through the creation of a .Net api definition and interaction with a smart contract (deployment, transactions, calls and events). Members of the Nethereum team will of course be there to answer any questions you may have regarding Ethereum programming and its cumulated benefits when used in the .NET context.

The Trinity Ethereum Client - A platform for blockchain applications

Trinity is a new full client for the Ethereum network. This talk will cover three main areas. First, highlighting the role that Trinity plays in the research and development of the core Ethereum protocols. Second, that once Trinity is no longer in an alpha stage that it will be a production client which you can use as core infrastructure. Last, explaining the "Plugin API" being developed for trinity as well as exploring the planned use cases we foresee it being used for.

Turbo-Geth: optimising Ethereum clients

As Ethereum network becomes gets more and more use, the load on the system grows, and the scalability becomes the primary concern. While concepts like Plasma, State Channels, and Sharding offer medium to long term solutions, client software optimisation have a potential to create enough runway in the short term. Turbo-Geth is an experiment to challenge various design choices made in major Ethereum clients and see the outcome. It is currently a fork of go-ethereum, but hopefully the insights are applicable to other client implementations too. This presentation will report on main experiments, findings, benchmarks, and the current state of Turbo-Geth project.

Year working with Geth on a production Ethereum application

AirSwap is a decentralized trading network. As Infura can attest, these applications end up making quite a few calls to Ethereum nodes. Most of the calls are simple lookup calls just checking balances. In addition, because the network supports trading there are many transferring token calls as well. This talk focuses on the evolution of AirSwap's geth infrastructure through the course of the year and how the setup has changed. We started from using Infura, to a single node, to making an in-house cluster. Along the way, we've experienced down times, slow syncs, and code issues. While, the infrastructure is bound to change as the ecosystem shifts, we'd love to share what we've learned and a bit of our setup.

Monitoring an Ethereum infrastructure

Have you ever wondered what goes on under the hood of an Ethereum node? Frankly, most people don't care. If you are, however, running production systems with multiple nodes across geographical locations, knowing what your nodes do internally is more important than you might think.It is a general fallacy to believe that a software either works, or does not. In reality, there is a whole spectrum in between. A software almost never works perfectly, rather there are quirks that may or may not affect your use case. These quirks may manifest only above a certain load or compound as time passes. The only way to build out a robust infrastructure, is to accept that your nodes are quirky. Instead of getting surprised when they break - having no idea what caused it - you must always be aware of buildups and correlations to external stimuli. This talk will present the suite of metrics that Geth exports for monitoring, highlighting why these have been added and why they might be important to you. By correlatinh your own load and use case with Geth's internals, you'll be able to gauge issues before they ever get strained enough to cause catastrophic meltdowns.

Trains, Planes and Network Upgrades: A Regular Release Cadence

How does an Ethereum Improvement Proposal (EIP) get deployed onto the Ethereum mainnet? At times it feels like an ‘80s buddy comedy, but as part of the Ethereum 1.x initiative, the process should become as predictable as a clock. In this talk, we will propose a regularly scheduled process modeled after Linux distributions and the Java platform that Ethereum could use for its future network upgrades. Frequent and regular network upgrades will remove the time pressure to submit and review EIPs, provide predictability to applications building on Ethereum and reduce the burden on core developers to begin implementing improvements that are not ready. Once a network upgrade leaves the station, another one will be coming right around the corner!
