This is straight up.

In the simplest way possible without much grammar involved, they are just fees paid to miners in order to process a transaction on the blockchain.

But, I think you should take a second look on this, because I know Ethereum uses Proof-of-Stake, instead of Proof-of-Work.

If you dig deep or are already familiar with the etheruem blockchain then you'll know that the etheruem blockchain runs on the 'Proof of work' consensus mechanism which usually involves lots of computational power to process and each computer that process transactions on this blockchain are referred to as nodes.

The concept of "Wei" is actually new to me, and thanks for the insight, I have to research on it for more understanding.

Now what's a 'wei'? Well let's just say its the metric system of the etheruem blockchain and every transaction. Just like we measure meat in Kilograms and speed in meters etc. 1 eth is equal to 1 quantillion wei ( 18 zeros).

I totally agree with you, the Ethereum blockchain tends to charge high transaction fees.

Thanks once again for your publication.
I had to follow up, after you commented on my post.
I hope you don't get offended on my suggestions, we are learning together, and I am glad that as a newbie you have been able to bring out this well organized and interesting article.
Keep it up. 🤗
