In the movie, a brother and sister see that a Hacker can simply press a few keys to change the balance in a bank account or hack the data. But with Blockchain, it's not nearly as easy to hack as it is in the movie. Why is that? Because it's practically impossible.
🔸 Each block contains a unique digital fingerprint (Hash). Just changing a single comma in the transaction data will completely change the Hash code to another string of characters.
🔸 Blocks are tightly connected to each other. The next block contains the hash of the previous block.
If a hacker secretly changes the data in Block number 10 -> The hash of Block 10 changes.
Block 11 contains the old hash of Block 10, which will result in a mismatch error -> Block 12 is hacked -> The entire subsequent chain structure collapses like dominoes.
🔸 To successfully hack, a hacker must not only enumerate the entire chain but also synchronize this fake data on 51% of computers worldwide simultaneously. This costs significantly more than the amount of money you plan to steal. A hacker is not foolish enough to waste time and money on work that does not yield profit.
🔹 A secure blockchain is not because it has thick walls, but because its economic structure turns all attempts at fraud into a financial disaster for the attacker. Hackers are rational people; they do not attack if Costs > Profits.
If you mistakenly transferred money, you will no longer be able to intervene. Do you prefer this absolute security or the flexibility of a bank?
