All these talk about using computational resources to mine blocks are peas in a pod with the growing concerns for the environment. Increased computational workload leads to an increased electricity consumption.

Proof-of-Stake attempts to solve this. More on this later.

When it comes to Ethereum and transactions on the blockchain, there is a common term that comes alongside: Gas.

What exactly is gas, and why do we even need gas?

[Revontulet @ffrevontulet]

Hence, while gas may be a nuisance and a pinch to the pockets of retail investors, it is but a critical component of a running and functioning blockchain, where there are incentives to being users and miners alike.

[Revontulet @ffrevontulet]

Note: Regarding individual participants who maintain and validate the state of the blockchain,

we typically associate nodes with a Proof-of-Work consensus mechanism and validators with a Proof-of-Stake consensus mechanism.

[Revontulet @ffrevontulet]

Let's dive a little bit deeper into Ethereum.

Ethereum has a native cryptocurrency called Ether ($ETH) and the state of the blockchain is based on the Ethereum Virtual Machine (EVM), which is the state agreed upon by all participants.

[Revontulet @ffrevontulet]

Participants in the Ethereum ecosystem that maintains and validates the state of the blockchain are known as nodes.

They are the very core of decentralization and the reason why the blockchain can function as required.

[Revontulet @ffrevontulet]

Some really useful traits about the blockchain:
1. Transparent
2. Decentralized
3. Immutable

Everything operates in a free market manner based on the fact that no one single entity owns the blockchain.

I dunno … seems kinda fungible

The Sun is about to run out of hydrogen in 5 billion years, and when that happens, life on Earth will cease to exist.

Earth would not be around long enough for you to fully crack the 256-bit encrypted hash.

[Revontulet @ffrevontulet]

This is a nice visual graphic that shows what hashes are. They are generated through a hash function, where the input in our case is the elements contained within a block.

A simple change in one letter will cause an entirely different hash to be produced.

[Revontulet @ffrevontulet]

Using an upper limit on Bitcoin's current hash rate, let's say you can compute 1.6 x 10^20 hashes per second.

You would then need 3.6 x 10^56 seconds to solve for that key in the worst case scenario. Converting to years, you would need 1.2 x 10^49 years to fully do so.
