In 2010, at block 74638, a flaw in the Bitcoin code allowed a transaction to create over 184 billion bitcoins due to an integer overflow of an int64 data type.

Integer overflow occurs when a number exceeds the maximum value that can be stored in a data type, causing it to wrap around. For example, an int8 can store values from -128 to 127, so adding 1 to 127 causes it to overflow and wrap around to -128.

Let's simulate a int8 overflow. By clicking on this window, you can increment the click counter. Try to exploit the overflow to get the counter to 0 and unlock the secret image.
