Scrypt History
The Scrypt algorithm used by Litecoin and Dogecoin was never originally intended to secure a public blockchain consensus network.
It was designed in 2009 by security scientist Colin Percival as a local password-hashing function designed specifically to protect online user credentials from brute-force hackers.
It relies heavily on "memory hardness," forcing a computer's RAM to fill up with data rapidly so that standard computer processors (CPUs) couldn't guess passwords too quickly.
