Cryptocurrency Hashing Algorithms Explained 2024
Each cryptocurrency uses its specific encryption algorithm. The mining equipment decrypts, ensuring the functioning of the blockchain, processing transactions, and receiving rewards in the form of coins of a particular cryptocurrency.
Without further ado, let’s dive into the world of crypto hash functions.
What Does Hashing Algorithm Mean?
A digital currency is encrypted using a set of particular cryptographic principles and procedures known as cryptocurrency algorithms. The algorithm of a certain coin is decrypted by miners using specialized equipment. This procedure entails locating a hash.
A new block is created in the blockchain as soon as the proper hash is discovered. This block contains data about transactions, the hash of the previous block, the amount that the miner received, and other details.

A collection of random data is transformed into ordered, systematic information through the decryption (also known as coin mining) process, which is then stored in the blockchain.
Several hundred cryptocurrency algorithms exist today.
Certain algorithms are more widely utilized and use https://www.simplilearn.com/tutorials/cyber-security-tutorial/sha-256-algorithm for a variety of cryptocurrencies (blockchains). For example, SHA-256, Scrypt, Ethash, X11, Lyra2Z, Equihash, and RandomX are the most widely used algorithms. Below, we’ll go over each of these.
SHA-256
The Bitcoin code has made the secure encryption technique SHA-256 more well-known. The Bitcoin algorithm creates a 256-bit hash, or a string of 256 bits, and SHA stands for Secure Hash Algorithm. For SHA-256 based coins, the hash rate is measured in gigahash per second (GH/s).
The creation of a block takes six to ten minutes. The SHA-256 algorithm was created in 2001 by the US National Security Agency. It belongs to the SHA algorithm family.
Currently, it is the only cryptocurrency algorithm in this family that has successfully passed the test for resilience to attacks like collision detection and inverse image detection, and it offers a clear solution for cryptocurrency security.
SHA-256 is extensively utilized in a number of different technologies in addition to cryptocurrency. For instance, the way SHA-256-based security protocols like TLS, SSL, PGP, and SSH function.
When Bitcoin was still relatively unknown in 2009, mining was done on regular PCs that used a central processor to do calculations. More potent graphics processors were later used. However, Bitcoin is currently incredibly popular.
Script
Scrypt is a mining algorithm for cryptocurrencies. In a blockchain that uses Scrypt, blocks are created in roughly 30 seconds.
Megahash per second (MH/s) is the unit of measurement for hashrate. Because of the cryptocurrency Litecoin, Scrypt gained popularity.
What is Litecoin (LTC) cryptocurrency about?
It quickly became evident when the Scrypt algorithm was developed that it is relatively simple to monopolize bitcoin mining since the SHA-256 function’s simplicity makes it possible to automate the mining process.
Because Scrypt requires more resources for computational activities, its primary goal was to make the block generation technique more complex.
While the power consumption and processing power needs are significantly lower than in the case of SHA-256, the amount of RAM is very important. At first, Scrypt-based coins were extracted using central and graphic processors.
But the algorithm was unable to withstand mining companies, and the first ASIC for Scrypt coins was developed in 2014. The following coins are based on the Scrypt mining algorithm:
- Litecoin (LTC)
- Dogecoin (DOGE)
- Syscoin (SYS),
- Viacoin (VIA),
- Redcoin (RED).
RandomX
RandomX is a proof-of-work method designed to work best on general-purpose processors (CPUs) and graphics cards (GPUs).
The innovation’s primary function is to load the device memory and execute various code segments in a random order.
RandomX makes use of a virtual machine that executes applications using a unique set of instructions. It is possible to quickly translate these programs into processor code.
Consequently, the Blake2b cryptographic hash function is used to merge the output of the performed programs into a 256-bit result. Both CPU and GPU mining are supported by Random X (AMD and Nvidia).
On RandomX, the majority of 2011 CPU types from AMD and Intel should operate rather well, as should visual cards with at least 2 GB of RAM.
Because they lack the time to dynamically change their circuitry, standard FPGAs are unable to operate on RandomX. By simulating the CPU, more effective models can mine on this technique.
But compared to the same CPUs, FPGAs will be far less efficient. Coins that make advantage of RandomX: Quantum Resistant Ledger (QRL) Monero (XMR).
