Dan joined the Ethereum Foundation in April 2021 to help with testing infrastructure. A strong believer in client diversity, Dan is interested in creating shared testing tools that can reduce complexity across client teams, helping accelerate Ethereum development and resilience.

In this workshop you can find a bug in an EIP implementation on a test network!

The Ethereum Foundation Testing Team oversees cross-client execution specification testing, which is critical to avoid consensus issues at the smart-contract execution level.

You'll implement tests for a new EIP from scratch using the ethereum/execution-spec-tests framework and execute them on a local test network with a faulty client. Anyone attending has the chance to find the issue and break the network!

Hunt the Bug, Save the Chain: Uncovering Bugs in EIP Implementations

We'll give an overview of Ethereum Execution Spec Tests (EEST), the new Python framework used since Shanghai to generate test vectors for Ethereum Virtual Machine (EVM) implementations. By generating tests programmatically this modular framework allows test cases to be readily parametrized and dynamically executed against clients on live networks. It tightly integrates with the Ethereum Execution Layer Specification (EELS) and could potentially be used across the L2 EVM ecosystem.
