FREE ONE-DAY Advanced Ethereum under the hood EVM Developer Workshop

Please make sure you register on Eventbrite to attend this advanced EVM workshop: https://www.eventbrite.com/e/free-one-day-advanced-ethereum-under-the-hood-evm-developer-workshop-tickets-59168248825 About the Advanced Ethereum (EVM) Developer Workshop: This full day workshop is open for those who already have industry experience, understand the main building blocks of blockchain technology and have worked with Ethereum platform either as Solidity developers or infrastructure engineers. During the workshop, we discuss in-depth the EVM client architecture, p2p protocols, and available consensus algorithms. We look in details at properties of transactions, block headers, logs and Bloom filters. We discuss the structure of Patricia tries, discuss performance of IO, network and EVM processing. We will go through a series of coding exercises written in EVM byte code which will allow us to discuss the lowest level operations of the Ethereum decentralized computer. We access EVM memory, long term storage and execute basic calculations using the EVM opcodes and discuss the gas cost optimizations and contracts security on the way. What makes this workshop unique? Big part of the workshop is actively driven by questions from participants and so each workshop edition looks slightly different. This is a unique characteristic of a workshop where most of the participants come with specific problems to solve in their minds, looking for explanations to the most difficult topics that they encountered while self-studying Ethereum. Who can benefit from this workshop? This is an advanced technical workshop aimed at Solidity developers or infrastructure engineers. At this workshop, people around you are blockchain entrepreneurs, researchers and experienced developers. For researchers, it is a great opportunity to cover the topics outside of their focus area and exchange ideas, for developers an opportunity to look at low level optimizations and security of their contracts and decentralized apps, for entrepreneurs a chance to test whether their business ideas can be supported by the technology at the current stage. Instructor: The workshop is run by Tomasz Kajetan Stanczak, CTO and Founder from Nethermind. What you need to do prior to attending the workshop? We use the Nethermind client to execute all the Ethereum operations. Before attending the workshop, all participants are expected to build and launch a Nethermind Görli node on their machines. What is the minimum requirement to be selected for the workshop? We assume the participants to have a basic understanding of the assembly language, memory, stack, hexadecimal systems and hash functions. What next after the workshop? If after workshop you are hungry for more, you can contribute to the open source Nethermind project on Github. Nethermind is still under development and there are parts of Ethereum protocol that still need to be looked at. This is a great opportunity to further advanced your knowledge on Ethereum with further support from the Nethermind team.
