Scrypt is a hashing algorithm used as the computational foundation of many cryptocurrencies, including Litecoin, Dogecoin, and a number of others. Scrypt was originally developed as a function that demands large amounts of RAM. This approach was intended to make mining more accessible on ordinary processors and graphics cards and more resistant to specialized hardware.

The key difference between Scrypt and the classic SHA-256 algorithm is that it deliberately loads memory rather than just computing power. This made it harder to build narrowly specialized devices. Over time, however, manufacturers developed ASIC devices for Scrypt as well, which reduced the algorithm's original advantage in terms of resistance to specialized mining.

Features of the Scrypt algorithm

• Increased memory requirements during computation;
• An initial focus on CPU and GPU mining;
• Use as the foundation of several well-known cryptocurrencies;
• The emergence of specialized ASIC hardware over time.

Scrypt became an important part of cryptocurrency history as an example of an attempt to make mining more decentralized. Knowing how the algorithm works helps you better understand the differences between networks and approaches to protecting against excessive centralization of computation.
