The Problem with Blockchains

Why most blockchains can't be used for real payments

Imagine This...

You just got paid. Your salary hits your account. Normally, that's privateβ€”between you, your employer, and your bank.

But what if everyone could see it?

πŸ”“ public-blockchain.log
βœ“Salary: $75,000/year
βœ“Payment: $1,200 to landlord
βœ“Balance: $8,543.21
βœ“Coffee: $4.50
βœ“Every transaction ever

All visible to everyone, forever

πŸ”’ private-normal.log
βœ—Hidden from public
βœ—Only you see details
βœ—Bank keeps it private
βœ—No one tracks you
βœ“Your financial life is yours

This is how it should be

Sounds insane, right?

That's How Most Blockchains Work

Every Bitcoin transaction is public. Every Ethereum payment is visible to the world. Forever.

πŸ“’ public-ledger.log

Anyone can view your entire financial life:

β†’0xABC... β†’ 0xDEF... $500
β†’0xABC... β†’ 0x123... $1,200
β†’0xABC... β†’ 0x456... $4.50
Current Balance: $8,543.21
Total Received: $75,000
All transaction history visible forever
⚠try it yourself

Go to any blockchain explorer (like Etherscan). Pick any wallet. You can see their entire financial life. Every transaction. Every balance. Everything.

Why this is a problem:

Companies:Can't do payroll (everyone sees salaries)
🏦
Banks:Won't use it (privacy laws)
πŸ‘€
You:Don't want finances exposed

Privacy isn't a luxury. It's a requirement.

Enter Aleo

Aleo is different. It's a blockchain where privacy is the default.
