How long non-finality could kill Ethereum

Duration: 00:16:01

Speaker: Dapplion

Type: Talk

Expertise: Intermediate

Event: Devcon

Date: Nov 2024

After the merge, Ethereum has a finality gadget to provide an economic assurance that transactions will never be reverted. When 2/3 of the validator set are online and agree, we finalize. Otherwise, we enter a period of non-finality which can be very long, up to a few weeks. Long non-finality has never happened in Ethereum's history and could trigger a cascade of failures that will kill liveness. How can we harden the network against this? How high are the stakes?

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.

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).

EVM Object Format (EOF): Managing the Bytecode Chaos

Currently, EVM bytecode, while being powerful and simple, is lacking structure. This leads to many complexities when introducing new EIPs and maintaining backwards compatibility. In this talk, we illustrate some use cases of the EVM Object Format (EOF). Next, we provide a quick overview of the main changes introduced by the EOF and related EIPs, along with code examples. Finally, we discuss potential benefits and drawbacks that could arise with the introduction of EOF

Decentralizing access to Ethereum utilizing Ethereum's Portal Networks

Accessing Ethereum in a decentralized way has a high barrier to entry for reasons of cost (hardware), knowledge, or time. These problems cause users to rely on centralized providers. A few examples on how Ethereum's Portal Networks will tackle these centralizing forces - EIP 4444's + Portal History will allow nodes to maintain current day RPC, well saving 800GB of storage. - Portal State will allow wallets to use a decentralized backend instead of a centralized backend like Infura.

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
