# dApps - Decentralized Applications

## <mark style="color:purple;">**Decentralized Applications**</mark>

PayPal, Facebook, YouTube....these are all web & mobile based apps.

We will be interacting with similar apps, except our "Log-in" will be our crypto wallet.

<mark style="color:blue;">**Q: Do I need to sign up with Email to access these decentralized apps?**</mark>

A: No, Your wallet is both your bank and your log-in.

<mark style="color:blue;">**Q: If I lose access to my wallet, do I loose access to my "account" on an app?**</mark>

A: Yup, your wallet is literally your master key. Keep it safe!

<mark style="color:blue;">**Q: Do these ask for permission to connect to my browser or physical wallet?**</mark>

A: Yup, you have to manually approve the 'log-in', and any transaction thereafter.

## <mark style="color:purple;">**Why Decentralized Apps?**</mark>

Have you ever used Wikipedia?

Now it's not a decentralized app, but the way it works, is decentralized.

Everyone in the world having the ability to edit a wikipedia page, gives it more accuracy.

This enables fact checking on a global scale, and while there can be bad actors, they are quickly dismissed during the fact-checking stage before publishing changes to the actual article.

If a 21-person company called HiFrance started a wikipedia competitor, but only those 21 employees could edit and create articles, that would be a centralized source of 'facts'.

I prefer my sources to be fact checked by the world, rather than 21 people .

**Q: Who owns a decentralized network?**

A: Everyone and no one. 🙂 Isn't that beautiful?

{% hint style="success" %}
This means people can build applications on this "globally owned" network, which can't be shut down by a pro censorship government, or by a unethical C.E.O
{% endhint %}

And this is why DeFi and decentralized apps prefer to be built on Ethereum. Ethereum is the most secure and most decentralized blockchain for building.
