Which Layer 2 approach is for you?

Here we will paint an overview of Layer 2s for developers deciding to build their own chains, scale Ethereum, or make a transition to Layer 2.

Why do you need to consider this?🤔

Different applications need different levels of security, decentralization, or scalability. Based on their demands there are at the moment different approaches to moving into blockchain-based platforms. 🌐

Take non-financial platforms such as gaming 🎮 or social media 📱, for instance:

These realms thrive on decentralization, yet their security needs are not one-size-fits-all. Consider the diverse facets of a social media app:

  • Critical functions like registering usernames 🔐 and recovering accounts demand robust security, ideally managed through a rollup.

  • On the other hand, everyday actions like posting 💬 or voting 👍 can afford a lighter security touch.

Why?

Because the stakes are different. If a glitch in the chain makes a post vanish, it's a minor hiccup 😕.

But if the same glitch locks you out of your account, it's a crisis 🚨.

This nuanced approach to security ensures that each aspect of the app receives the attention it deserves, balancing efficiency with safety.

Vitalik summed it up efficiently using the following scale:

What to expect?

We will discuss each Layer 2 solution with examples and ups and downs and guide you to more in-depth resources regarding each of them 📚.

We will have a special focus on transaction cost 💰, and the applications of these Layer 2 options, to help you with your decision-making 🤝.
