Optimistic Execution: Putting the Internet on Ethereum
Ethereum can serve as an arbiter of trust for the entire internet. To make this a reality we'll have to scale. Our best bet to scale is constructing a comprehensive layer 2.What do plasma, state channels, optimistic rollup, & ETH2 have in common? Optimistic execution! Or in other words, they each make inferences about future Ethereum state based on local information--think fork choice on top of a state machine. Using this concept we construct the Optimistic Virtual Machine (OVM), baking inference logic directly into wallet & application software. In this talk we discuss how the key role trust will play in the internet--from DeFi to timestamping--and how we can build the underlying infrastructure to support internet scale. These are exciting times for blockchain infrastructure. Now we just need to solve identity & UBI -- easy!
Optimism’s OP Stack
Introducing the OP Stack — a standardized tech stack for L2 chains. Introducing the Superchain vision — the inevitable unification of the distinct L2 chains into a single, horizontally scalable, super-sequenced, Superchain! The OP Stack is how we realize the Superchain vision.
Plasma Implementers Call Live!
The Plasma Implementers Call is a biweekly call which discusses the cutting edge of Plasma research. We will be doing a LIVE session! This is a great group of 9 people: Joseph Poon, Karl Floersch, Kelvin Fichter, Dan Robinson, David Knott, Xuanji Li, George Konstantopoulos, Alex Vlasov, & (if I can convince him) Vitalik! You can take a look at the YouTube channel here: https://www.youtube.com/channel/UCG2MeKuKDJRK4gFNk-dQuZQ Please subscribe! ;)
Scalable Blockchains & Asynchronous Programming
Ethereum's Vitalik Buterin presents on scalability and asynchronous programming.
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.
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.

INCUBED - A trustless incentivized decentralized remote node network
To enable smart devices of the Internet of Things to be connected to the Ethereum blockchain, an Ethereum client needs to run on hardware. While running a full-node or even a light-client on most IoT devices with low performance or restricted resources is not possible or meaningful, today's state-of-the art solution uses a remote client. By using distinct remote-nodes, the advantages of a decentralized network without being forced to trust single players are undermined and there is a risk of malfunction or attack because there is a single point of failure.With the presented Trustless Incentivized Decentralized Remote Node Network, in short INCUBED, with a stateless minimal verification client it is possible to establish a decentralized and secure network of remote-nodes, which enables trustworthy and fast access to blockchain for a large number of low-performance IoT devices.
A Better Mental Model for Rollups, Plasma, and Validating Bridges
Sidechains, Plasma, Rollups, Valdiums, AnyTrust, PoS chains, Crypto Exchanges, all have one thing in common: the bridge. This talk provides an overview on the trust assumptions, threat model, security goals and solutions associated with the humble bridge smart contract. As we will see, rollups emerged because of the scalability bottlenecks faced by Ethereum, but the product-market fit is solving the operational security issues for bridging funds from Ethereum to an off-chain system.
On the Path to a Rollup-Centric Future
It’s only been slightly over a year since Arbitrum launched as the first optimistic rollup that supported general EVM contract deployment. In that time many components have shifted, many users have migrated, and an entirely new generation of technology has shipped with Nitro. Now we look towards tackling the next set of challenges in working towards Ethereum’s rollup centric future, where using Ethereum will mean using a rollup.
