Intro

Ethereum uses a consensus protocol called Proof-of-work (PoW).

This allows the nodes of the Ethereum network to:
- agree on the state of the recorded info in the blockchain
- prevents some economic attacks.

In the future, it will be replaced with Proof-of-Stack.

Ethereum Networks thread.

Key concept: Ethereum is not a network, but a protocol that can be implemented to create different networks.

The most famous, mainnet (used for Ether, the cryptocurrency), is one of them.

What's the difference between Public and Private networks?

Intro

Ethereum is a protocol: there are many independent networks that implement this protocol

Networks are different Eth environments to:
- develop
- testing
- prod

Your account will work across the different networks but your balance/transaction history won't carry over.

🔲Ethereum Nodes as a Service thread.

Yesterday we have seen how to spin up your won node.

But what if we don't have time to do that, or we want to rely on an existing infrastructure?

Many different services exist that can do this for us.

Let's see this in 1 min.

Intro

Running your own Ethereum node can be challenging.

This is especially true if you are new to the Web3 world.

Node services run optimized node infrastructures, so you can focus on developing the app itself.

⚠Node services should NEVER store your private keys/info.

🔲DECENTRALIZED STORAGE thread

Many of us have an idea of ​​what a database is, but how do we behave when dealing with Ethereum?

We can use something called Decentralized Storage (dStorage for frens)

The good news is that Ethereum itself can be used as a DB.

but ...

dStorage systems are p2p network of user-operators who hold just a portion of the overall data.

By doing so, they create a resilient file storage sharing system.

Two options.

dStorages can be:
- in a blockchain-based app.
- in a p2p network.

I've dealt with a lot of negative comments in my life.

When I was a coach I had people yelling at me who didn't agree with my choices.

That's why IDGAF on a comment written by an anonymous user who hides behind a keyboard.

But someone does.

So I wrote 6 things FOR YOU.

↓
1- Never take it personally:

Think they:

- had a bad day,
- just broke up.
- lost their job.
- had their car stolen
- had their house burned down

But don't take this as a direct attack on YOU. it's not about what you have done.
2- Responding is usually more harmful than ignoring.

This does not mean that we must passively accept any accusation, but probably answering it will only fuel discussions.

Also, there are people who like to argue all day long.
That's their hobby.

Block explorers are like a search engine for a blockchain.

They provide insight into every blockchain's aspect, by enabling to search for real-time and historical information about a blockchain, for example:
