Update the blogposts on the new homepage

[Dominik1999]

The blog posts need some new graphical elements. We should use the simple Excalidraw style for it.
Also, since the product and its vision have evolved, we might want to adjust the language in the posts.

Here is the source code https://github.com/0xPolygonMiden/miden-homepage/tree/master/src/components/blogPosts

Adding below the cover images for each blogpost:

1. Ethereum Extended

2. A new transaction model:

3. How every asset is native:

4. Privacy scales better:

5. State model:

Thanks for the suggestions! Maybe let's take some inspiration on our slides here. For most topics we already have graphics, maybe we can reuse them. However, I don't think we need a cover graphic, but graphics that make it easier to read the text. For example, in this blogpost (https://polygon.technology/blog/polygon-miden-ethereum-extended), there is a graphic about the different transaction modes. We again need such a graphic, without it the reader doesn't understand the text.

About 1:
It would be cool to show in the picture how we extend Ethereum. At the moment, it looks more like what you can do on Ethereum. So, we make Ethereum more scalable and more private.

About 2:
I don't get the picture completely. Are those three transactions? For transactions, we normally use this picture:

Maybe we can do a simpler version of it. The core differentiator / new transaction model is that a transaction is only executed against a single account.

About 3:
I don't understand how this graphic shows that assets are native. I am also unsure to show that in a simple graphic.

About 4:
Maybe we can use something like this graphic?

About 5:
I think in Miden the state doesn't get smaller. But again not sure how to show it properly

Ignoring the cover pictures and only posting the pictures that go into the middle of the posts; kept the content in all of them as it is in the original and only followed a same consitsent styling:

2.3

2.4

Nice, thanks for the update! I think we can use most of them already. But we are not there yet.

A couple of comments:

On 2.2. and 2.3:

• Can you make the boxes a bit smaller or the font bigger?
• Also for 2.2. in the box right below there should be Acct1' to indicate it is the same account in a new state.
• Also the arrows look a bit weird, can you maybe use the thicker arrows?
• Can you make the Account box and the note box differently? (We use a diamond for a transaction, a rounded square for an account and a normal square for a note (like a banknote).

On 2.4:

• That looks a bit weird (it also already looked weird in the original version. Can you try to come up with something better? (e.g., the notes look like real dollar notes, but we have tx as a subtext). There is a slide that explains this

On 4.1:
I think you used your Miden logo, which looks cool. But can you remove that until we agreed to use it? Also why is one account in color and the other is not? And again, please use the shapes described under (On 2.2 and 2.3).

On 5.1:
5.1 and 1.1. is the same thing, right? Can you use the same picture then?

On 5.2:
Can you indicate that the note hash and the nullified hash are two different hashes. You can do that by writing out the structure of the hash (note hash = hash(data1, data2, ...), nullified = hash(data2, data1).

You can find the definition of those in our docs.
