Ethereum 2.0 implementation updates 4Q2018/Prysmatic Labs: Implementing Ethereum 2.0 Today

The sharding implementation updates 4Q2018, mainly on Python side. // Sharding and layer-1 scalability are perhaps the most important, forward-thinking changes that Ethereum 2.0 will implement. Ever since the inception of the Sharding FAQ by Vitalik, both the foundation’s research team and the community have actively engaged in bringing ideas together into a solid specification and road ahead for the future of Ethereum. This task will focus around the ins-and-outs of building the high-level Ethereum 2.0’s Casper & Sharding spec into granular code by one of the main sharding implementation teams, Prysmatic Labs. We will analyze caveats we ran into when designing Ethereum 2.0 while the research is still in flux. Ethereum 2.0 encompasses a lot more than software upgrades, as it gives developers the opportunity to pave a path with better design capabilities, a better open source contribution ecosystem through documentations, and a more modular, pluggable set of tools built to last the test of time. We assembled organically as a team to build this out, and we aim to give back to the community from what we have learned so far in terms of building on a volatile research spes, attracting open source talent, mitigating technical debt, and why transparency and public work are important.

SWARM Team Update
Swarm aims to be the native data storage and content distribution infrastructure layer of the "Web 3.0".Since our last update at Devcon3 in Cancun, Swarm has seen major progress in its codebase. The long awaited network rewrite has been completed and several new features have been merged. In this talk members of the Swarm Team will present quick updates. For example, here are some of the updates we'd touch upon: -Encryption - Since the 0.3 release Swarm supports native encryption on the chunk level. Daniel will present a quick overview. -Access Control Trees - newly introduced in Swarm is the support for Access Control Trees. This feature increases the utility of Swarm to a wide range of use cases. Elad will sketch the main features. -Swarm Light Client - The requirements and limitations of the mobile phone present unique challenges for Swarm and we have begun to address them with the Swarm Light Client. Attila will give an update on this project. -PSS - The PSS protocol has matured significantly since last year. Lois will give the update. -Spam prevention in Swarm - new ideas for countering a flood of bad data. (dani & Aron) -Databases in Swarm (Viktor)

Rollups, Shards & Fractals: The Dream of Atomically Composable Horizontal Scaling
Rollups allow blockchain to scale vertically, while preserving their trust properties. But what do we do when we reach the limits of vertical scalability? It might also be desirable to accomodate multiple rollups with different operating rules, virtual machines, or security trade-offs. Horizontal scaling solves these issues, but doesn't allow atomic composability. In this talk, we review approaches to horizontal scalability & ways to get as close to atomic composability as possible.

The Mauve Revolution
Proof of stake and sharding present two of the biggest upcoming milestones in the ongoing development of the Ethereum protocol. Proof of stake offers the promise to greatly reduce the cost of consensus and increase security guarantees, while sharding presents an approach to allow on-chain scaling to tens of thousands of transactions per second while still retaining a network that can, if needed, run on nothing but a sufficiently large set of consumer laptops. The Casper approach to proof of stake also introduces a number of novel concepts, including consensus-by-bet and fork choice by value-at-loss.

P2P Networking in Ethereum 2.0
Sharding and Casper promise to greatly improve performance, sustainability, and security of the Ethereum blockchain. Alongside a novel and much-discussed consensus protocol, they also entail fundamental changes to the requirements and constraints imposed on the peer-to-peer (p2p) networking layer. In this talk we report on ongoing research as well as the current implementation state of the latter. We begin by defining key qualitative and quantative properties the network should have. Then we discuss several options for both node discovery and gossip protocols, comparing their performance on the basis of simulationresults. Finally, we give an update on the current state and future developments of protocol implementations.

Raiden Network: Getting to a production ready payment channel network
The Raiden Network is the payment channel network for Ethereum aiming to help scale Ethereum payment and all Dapps that utilize Ethereum for payments and rely on no on-chain side effects of the payments. There will be a small explanation of what is payment channels and a payment channel network, an explanation of the raiden network protocol and a demo of using Raiden (hopefully by then live on the mainnet). We will close with future plans, expansion of the protocol and showcasing potential applications.

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.

Less Gas, More Fun: Optimising Smart Contracts through Yul
Due to the relative simplicity of the Ethereum Virtual Machine, it is possible to perform heavy analyses in order to optimize bytecode. The jump operations are a main obstacle for this, because they might require a preservation of all basic blocks in the worst case. To overcome this, Solidity's new optimizer operates on an intermediate language called Yul, which is close to EVM bytecode (and also wasm) but abstracts jump operations through real function calls. Each of the many optimizing operations are simple local equivalence transforms whose effects can be inspected at any time and which in combination should be both more reliable and efficient than the classic optimizer.

FunFair Technologies' Fate Channels: Lessons learned Implementing State Channels
Jeremy Longley, CTO of FunFair Technologies, will offer a post-mortem on the delivery of their own version of state channels, Fate Channels, to Mainnet. There have been significant challenges along the way, and there's likely to be many more to come as their use scales up. Having deployed a flexible and creative approach, Jeremy will outline how others can bypass these challenges and embrace state channels as best they can.
