Web3 Isn’t Replacing Web2 — It’s Rewriting One Layer of It

Look at the image above, the account address is not something I created but a token that can be accessed by everyone. What exactly is blockchain, I kept wondering and names like Web 3 only confuses and makes it look like it is something that will replace the web 2 infrastructure, but it is not so. What it actually is Database and blockchain only aspires to replace the database layer of Web 2 infrastructure while the UI/UX remain like Web2 apps.

But why to move from traditional database, well it is basically because the database is public and does not require any permissions. They do not require a centralized control or access rights.

As far as I have explored its applications are mostly centered around payments, trading and financial primitive.

I am open to be challenged about my understanding and at the same time really really looking to get more noise cleared around Web3.

📦 Account = Your Database Record (Owned by You)

In Web2:

Your data lives in a database row (e.g., user profile, balance)
The company owns and controls that database

In Solana:

An account is a fundamental unit for storing state on a blockchain network
It can store:

SOL balance
Token balances
App-specific data (like profile, game state, etc.)

👉 Key shift:

In Web2 → company owns your data
In Solana → accounts are owned/controlled by programs or your key

🔑 Key Pair = Username + Password (but better)

In Web2:

You log in with username + password
The server verifies your credentials

In Solana:

A key pair =
Public key → like your username (you can share it)
Private key → like your password (must stay secret)

But here’s the key difference:

In Web2, the server stores and verifies your password
In Solana, no server exists → you prove ownership by signing messages with your private key

👉 Think of it as:

Instead of sending your password, you prove you know it without revealing it
