Understanding the Ethereum Blockchain Protocol
Ethereum's Vitalik Buterin presents on the intricacies of the Ethereum Blockchain Protocol.
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.
VLSMs—analyzing faulty distributed systems
Validating Labeled State transition and Message production systems (VLSMs) provide a general approach to modeling and verifying faulty distributed systems. With formal definitions of validation and equivocation, we are able to prove that for systems of validators, the impact of Byzantine components is indistinguishable from the effect of the introduction of corresponding equivocating components. All of the results presented in this talk have been formalized and checked in the Coq proof assistant
Cryptoeconomics In 30 Minutes
Vitalik gives a quick overview behind Cryptoeconomics.
Yul, eWasm, Solidity: Progress and Future Plans
Over the last months, the Yul language has matured and proved its flexibility. The Solidity team has implemented an optimizer and an eWasm dialect and is now full steam working on rewriting the Solidity code generator to produce Yul code to replace sequences of EVM instructions.The Yul optimizer now matches the old EVM optimizer and already surpasses it with features like function inlining and cross-function optimization. This is also the main reason why the new code generator can be written in a super-modular way. Furthermore, it can equally operate on EVM- and eWasm-flavoured Yul code, which is important to cope with the 256- to 64-bit translation.Through this, the Solidity compiler can now output eWasm code, which makes efficient use of 64 bit types. Furthermore, the new code generator includes automated overflow checks everywhere, again something that would have destroyed the old optimizer. Future work:We plan to use a more intricate formal system to remove redundant operations and checks based on range-relations between variables. The introduction of memory area types will help optimizing memory allocation. Finally, a super-optimizer could prove useful, since it is worth spending extra time on compilation to save gas.

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.
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).
Anatomy of an Ethereum Client
The overview of the building blocks of an Ethereum client: what any client implementation should have. A practical perspective on how Ethereum works under the hood.
