Скачать или смотреть DeFi's Most Devastating Exploit: Flash Loans Decoded

Imagine borrowing $200 Million with no ID, no credit score, and no collateral. This is the 12-second reality of a Flash Loan.

In this episode of The Invisible Front, we deconstruct the "Atomic Weapon" of Decentralized Finance. Flash Loans allow anyone to become a whale for a single transaction block—but this power has turned DeFi into an adversarial battlefield. We break down the mechanics of the most devastating crypto heists in history, from the $130 Million Cream Finance exploit to the $197 Million Euler Finance disaster.

By the end of this video, you will understand:

The "Time Travel" Mechanic: How hackers use "Atomicity" to erase their debt if a heist fails.
The "Glitchy ATM": A simple visualization of Re-Entrancy, the code flaw that drains liquidity pools.
Price vs. Logic Attacks: Why reliance on "Spot Price" oracles is a death sentence for protocols.

Active Defense: How new systems like FlashGuard are using "Dusting Transactions" to counter-attack hackers in the mempool before they can steal a cent.
