Copying Memory in EVM, how hard can that be?
Duration: 00:08:15
Speaker: Elia Anzuoni
Type: Lightning Talk
Expertise: Intermediate
Event: Devcon
Date: Nov 2024
Memory copy operations in EVM are a useful feature, but there are different ways to do. How do they differ? Which is the best?
The options are:
MLOAD+MSTORE loop
Identity Precompile
The new MCOPY opcode
Based on concrete examples we will explain how these options differ. We will use different examples as the amount of bytes copied makes a difference. For all these options we will present gas consumption and code size.
This way we can compare the different options to copy memory and crown the ult

Reth 1.0: How did we get here and what is next?
Reth is an Ethereum Execution Layer in development since 2022, focused on contributor-friendliness, modularity and performance. In 2024, after rigorous testing and security review, Reth had its first 1.0 prod-ready release. In this talk, we review the process of shipping a state of the art & novel Ethereum node, and lay out Reth's plans for the next years.

Using Reth Execution Extensions for next generation indexing
Recently, Reth and Geth released the ExEx and live tracer features, respectively, which share similar functionalities. Both provide real-time, detailed access to chain and state events. As ExEx developers begin to persist this data and explore ways to make it accessible to users, new questions arise: how can we best serve this data to users, and what might the indexers of the future look like?

Optimizing full node costs with monitor tools
Running a full node is a fundamental component of participating in a decentralized network. However, the operational cost associated with running a full node can be prohibitively high, even for an archive node, it needs a lot of CPU/Memory and SSD disks. At our organization, we have successfully implemented a cost reduction strategy by using the pprof tool, along with grafana and prometheus in our node infrastructure.

Unpacking EOF: Applications in Developer Infrastructure and Tooling
In this talk, we will delve into the Ethereum Object Format (EOF), a pivotal component of the upcoming Pectra hard-fork, focusing on its profound implications for development infrastructure and tooling. EIP-7692 introduces a new execution environment and a structured format for executable code, bringing extensive changes to the Ethereum Virtual Machine (EVM). How will it affect developers? What will make their lives harder and what easier?

Ethereum in 25 Minutes, Version MMXVII
So what are all of the different moving parts of the Ethereum blockchain? What are uncles, how do contracts call other contracts, who runs them? What is the role of proof of work and proof of stake, and what exactly is gas? What will EIP86 do for you? Vitalik Buterin provides a 25-minute technical overview of the ethereum blockchain, start to finish, and explain many of these concepts in detail.

Exploring the Future of Account Abstraction
Discover the journey of Ethereum's Account Abstraction (AA) from inception to its current state, challenges tackled by ERC-4337, and future roadmap: modular native AA approach for L2 and L1, and EOA improvement (EIP-7702).

Native Account Abstraction in Pectra, rollups and beyond: combining EOF, EIP-7702 and RIP-7560
Account Abstraction has rightfully become one of the most discussed topics in the Ethereum ecosystem. The upcoming Pectra upgrade is set to be the first one to improve EOAs by including EIP-7702. But can EIP-7702 alone achieve "Account Abstraction"? We will discuss the challenges and benefits of EIP-7702, and break down the team's vision for achieving "complete" Native Account Abstraction with RIP-7560/EIP-7701 and how it differs from ERC-4337 + EIP-7702.

EIPs Simplified: History and Process Explained
It is planned to be an easy-to-understand session about Ethereum Improvement Proposals (EIPs). We'll explore the interesting history of EIPs and the important moments that have shaped different types and categories of proposals. Learn how EIPs go from an idea to becoming part of the Ethereum network, and see how editors help improve the standardization process. This talk is perfect for anyone who wants to learn about EIPs without getting into technical details.

Farcaster frames: building embeddable Ethereum apps
Frames are an open standard for creating embeddable, interactive apps in social media feeds and on the web. They help solve one of the hardest problems for Ethereum dapp developers: distribution. Although frames originated on Farcaster, it's now possible to build cross-platform frames that work on Farcaster, Lens, XMTP, and the open web. In this hands on workshop we'll introduce the core concepts behind frames and build a simple frame app that interacts with a smart contract.
