🔧 What Is a Protocol?

A protocol is just a set of rules that tech follows.

Like how roads have traffic lights — protocols keep crypto systems running safely.

Examples:

Bitcoin protocol handles peer-to-peer money transfers.

Ethereum protocol runs smart contracts and dApps.

Filecoin protocol helps store files across many computers.

🔓 What Does “Permissionless” Mean?

No gatekeepers. No middlemen. No needing to ask permission.

You can use crypto apps without signing up, giving your data, or being approved.

“Permissionless = walk straight in like it’s your own house.”

💡 Why It Matters:

You’re in control.

Anyone, anywhere can participate — no matter their location, credit score, or status.

It creates open, fair access to finance, storage, and services.
