Who Can Turn Off Your Ethereum App? A Full-Stack Walk-Away Test

People trust apps with their work, records, and communities. When an app disappears or falls under hostile control, users can lose access and other apps built on it can break.

This talk applies a full-stack walk-away test through three chapters: interface, data, and rules. Using Ethereum File System (EFS) and other Ethereum projects as examples, we will examine how people can keep using an app, recover and reuse their data, and rely on rules that no single operator can change. We will cover runnable releases, alternative access paths, shared data formats, replaceable services, and immutable smart contracts.

Developers will leave with a practical starting point: choose one important user task, test it without the team's services or help, identify who could block it or change its rules, and improve one dependency. The goal is software that outlasts its creators and remains useful for others to build on.
