ELI5: Explain Like I'm 5

Memory-hard function

Okay kiddo, so imagine you have a secret code that you want to keep safe. But just having a simple password like "12345" or "password" isn't very safe because someone else might guess it and access your information. That's why people sometimes use really hard passwords like "aBcD1234$!#".

A memory-hard function is kind of like making a really hard password that's almost impossible to break. It's like building a special puzzle that's really tough to solve, so it takes a lot of time and effort for someone to figure it out. You might have to use something called "memory" to solve the puzzle, which means you have to remember a lot of things and think really hard.

So by using a memory-hard function, you can make your secret code much more secure because it's hard for anyone else to figure out what it is. It's like putting a really strong lock on your diary so no one can read your secrets.
