🤔 Ethereum explained

The Daily Squeeze is usually charts, drama, regulations, gossip, and all that jazz.

But it's Back to Basics Week, which means we're slowing things down and explaining the stuff that powers basically everything in crypto.

Today's topic: Ethereum - the chain that turned crypto from "internet money" into "internet apps."

Let's clear this up right away: Ethereum is not just a cryptocurrency.

Yes, it has a coin (ETH).

But Ethereum's real purpose is being a decentralized platform where anyone can build applications without a company, server, or central authority running the show.

If Bitcoin answered the question,

👉 "What if money didn't need banks?"

Ethereum followed up with,

👉 "What if apps didn't need companies?"

Here's the core idea:

Ethereum is a blockchain that lets developers write smart contracts - pieces of code that automatically run when certain conditions are met. No middleman. No manual approval.

Once those contracts are live, they can't be changed or shut down by a single party.

That's the magic (and sometimes the chaos).

Here's how that plays out in practice:

Ethereum runs on a network of computers called nodes. These nodes all store the blockchain and agree on what's happening - who sent what, which contracts ran, and in what order.

When you do anything on Ethereum (swap tokens, mint an NFT, vote in a DAO, etc.), you're interacting with a smart contract. The network processes that action, records it permanently, and moves on.

That processing requires resources - and that's where ETH comes in.

ETH is Ethereum's native asset and is used to pay for transactions and computation (aka gas).

So ETH isn't just money - it's the fuel that keeps Ethereum running.

To keep this system secure, Ethereum relies on validators.

Validators lock up (stake) ETH as collateral and help verify transactions and smart contract activity.

👉 If they follow the rules, they earn ETH rewards.

👉 If they try to cheat, they can lose part of their stake.

This setup makes attacking the network expensive and aligns incentives so it's in everyone's best interest to play fair - all without a central authority in charge.

At this point, the difference between Ethereum and Bitcoin becomes clear.

👉 Bitcoin is intentionally limited. It focuses on being secure, predictable, and good at one thing: digital money.

👉 Ethereum is intentionally flexible. It's designed to be programmable.

Same foundation (blockchain). Very different goals.

And because Ethereum is programmable, entire ecosystems grew on top of it. This is where:

👉 decentralized finance (lending, borrowing, trading without banks),

👉 NFTs and on-chain ownership,

👉 blockchain games,

👉 DAOs run by smart contracts,

👉 and thousands of tokens

... all took off.

Ethereum became the default place to build in crypto.

Of course… it's not perfect.

Ethereum's biggest pain points:

👉 High gas fees: when lots of people use the network, fees can spike;

👉 Scalability: the base layer can only handle so much at once;

👉 Smart contract risk: code bugs can (and have) caused major losses.

A lot of Ethereum's upgrades and Layer-2 solutions exist specifically to fix these issues.

Bottom line:

Ethereum isn't just a coin - it's a platform. A programmable blockchain that lets developers build apps, organizations, and financial systems without a central authority calling the shots.

👉 Bitcoin showed the world decentralized money was possible.

👉 Ethereum showed the world decentralized everything else might be too.
