Only Cryptos

Ethereum explained

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.

Changpeng Zhao (CZ), the founder and former CEO of Binance, attended and spoke at the World Economic Forum (WEF) in Davos held from January 19 to January 23, 2026. During his appearances, he addressed topics like crypto payments adoption, meme coins, and fragmented regulations. 

Key Discussions and Initiatives
Sovereign Asset Tokenization: CZ disclosed that he is in high-level discussions with "probably a dozen governments" about using blockchain technology to tokenize state-owned assets to raise funds. He noted this could allow countries to realize financial gains first and use the funds to develop industries.
Crypto Payments and Meme Coins: He stated that crypto payments adoption has not met initial expectations and remains a non-mainstream method due to user habits and regulatory friction. He also warned that most meme coins are highly speculative assets with limited utility.
Regulation: CZ commented that global crypto regulation remains inconsistent across different countries, making a single global regulator unlikely in the near term. He suggested "regulatory passporting" as a more practical first step.
Banking Systems: He argued that the fractional reserve system is a structural weakness in traditional banking, which makes them vulnerable to liquidity crises that crypto exchanges like Binance have successfully weathered. 

Post-Sentence Status
CZ's attendance at the 2026 WEF was possible because he had completed his four-month prison sentence in September 2024 and received a presidential pardon in October 2025, which cleared his criminal record and lifted travel restrictions. The pardon also removed restrictions that might have otherwise prevented him from running certain financial ventures. While he cannot hold an executive management role at Binance permanently as part of his original plea deal, he remains the company's largest shareholder and continues to be involved in the broader crypto ecosystem through advisory roles and new projects like Giggle Academy, a non-profit education platform.
