What is mining?

Ethereum uses the proof-of-work consensus mechanism.

Mining: the process of creating a block of transactions that are added to the current Ethereum blockchain.

Ethereum miners use their time and power to:
- process transactions
- produce blocks.
Why miners?

In a decentralized system, everyone needs to agree on the order of transactions.

The production of blocks is done by miners who solve computationally difficult problems.

This is needed for security reasons and to protect from attacks
Who can become a miner?

Technically anyone.

But miners must purchase dedicated hardware to mine profitably, so not everyone can mine ETH with a profit.

To do this, they need:
- dedicated expensive hardware.
- consume energy.
Cost of mining

- HW to build and maintain a mining rig.
- Electrical cost of powering the mining rig.
- Additional support equipment (cooling system, ...).

In addition to that, there is also a cost in case you are in a mining pool group.
Mining Pools

A mining pool is a group of miners who combine their computational resources to increase the chances of:
- finding a block
- successfully mining.

There is usually a flat fee to pay for the generation of each block.

🎯Centralization VS 🌐Decentralization thread.

Do you remember NAPSTER?

If YES, sorry you are old my friend.

It was a centralized system for distributing pirated music.
Turned off the server, it stopped working.

Let's see PRO/CONS of centralized VS decentralized systems

Network

🎯Centralized
- All participants are connected to the central authority.
- Info propagates quickly.
- The central authority handles propagation.

🌐Decentralized
- Participants may be many edges away from each other.
- Information broadcasts may take a long time

10-Steps transaction mining process thread.

What are the main steps in the process of the mining of a new transaction on Ethereum?

Let's see this in 2 minutes in this thread.

Image
10 Steps:

1 Transaction signing
2 Transaction broadcast
3 Request added to mempool
4 Transaction request aggregation
5 Miner awards transaction fee
6 proof-of-work certificate
7 Block broadcast
8 Other nodes' verification
9 Mempool cleanup
10 New nodes sync

Start
1 Transaction signing

A user writes and signs a transaction request with their account using the private key.

🔲The Merge thread.

In 2022, is planned one of the most important moments for Ethereum: the Merge.

The Beacon Chain will merge into the Mainnet.

And we complain about Git conflicts.

Ethereum enthusiasts are waiting for it as Marvel fans were waiting for "Avenger Endgame".

What is the Merge?

The Mainnet currently works with the proof-of-work consensus.

The Beacon Chain, already shipped in 2020, runs in parallel using proof-of-stake.

The MERGE is when these two systems will collapse in a single one.

🔲The Beacon Chain thread.

The Beacon Chain is an exciting new feature for Ethereum.

You can think about it as a lighthouse for the Ethereum Blockchain.

It will introduce:
- staking
- shard chains

Let's see the key concepts.

Definition

The Beacon Chain is a brand-new, proof-of-stake blockchain.

You can think of the Beacon Chain as the main spine that will support the new Ethereum 2 system

It will coordinate all the concurrent actors.

🔲Shard Chains thread.

Today's thread was the most exciting one so far.

Shard chains could decide the future of the Ethereum blockchain (in a positive or negative sense).

Here are the concepts of sharding.

What is sharding?

"Sharding" is the process of splitting a DB horizontally to spread the load.

For Ethereum, sharding will create new chains (the shards)

Sharding will:
📉 reduce network congestion
📈 increase transactions per second

This is not just for scalability

🔲Proof of Stake thread.

After the proof of work thread, the proof of stake thread is a must.

This is the new consensus that will be used by Ethereum.

Many concepts will require a dedicated thread in the future

What is Proof of Stake (POS)

Users stake their ETH to become VALIDATORS.

Validators responsibilities:
- ordering transactions
- creating new blocks

Improvements:
✅more energy efficiency
✅reduced HW requirements
✅more centralization immunity
✅more nodes
✅shard chains
