Scrypt: C++ [10] PoW: One of the first cryptocurrencies to use scrypt as a hashing algorithm. 2011 Namecoin: NMC Vincent Durham [11] [12] SHA-256d: C++ [13] PoW: Also acts as an alternative, decentralized DNS. 2012 Peercoin: PPC Sunny King (pseudonym) [citation needed] SHA-256d [citation needed] C++ [14] PoW & PoS: The first cryptocurrency to ...
The scrypt function is designed to hinder such attempts by raising the resource demands of the algorithm. Specifically, the algorithm is designed to use a large amount of memory compared to other password-based KDFs, [ 6 ] making the size and the cost of a hardware implementation much more expensive, and therefore limiting the amount of ...
Litecoin was a source code fork of the Bitcoin Core client, originally differing by having a decreased block generation time (2.5 minutes), increased maximum number of coins, different hashing algorithm (scrypt, instead of SHA-256), faster difficulty retarget, and a slightly modified GUI. [citation needed]
Markus designed Dogecoin's protocol based on existing cryptocurrencies Luckycoin and Litecoin, [15] which use scrypt technology in their proof-of-work algorithm. [16] The use of scrypt means that miners cannot use SHA-256 bitcoin mining equipment, and instead must use dedicated field-programmable gate array and application-specific integrated ...

The Secure Hash Algorithms are a family of cryptographic hash functions published by the National Institute of Standards and Technology (NIST) as a U.S. Federal Information Processing Standard (FIPS), including: SHA-0: A retronym applied to the original version of the 160-bit hash function published in 1993 under the name "SHA". It was ...
It is profitable for exchanges to list low market-cap coins, despite the potential for 51 percent attacks, say two VCs from Dragonfly Capital.
Some other hashing algorithms that are used for proof-of-work include CryptoNote, Blake, SHA-3, and X11. Another method is called the proof-of-stake scheme. Proof-of-stake is a method of securing a cryptocurrency network and achieving distributed consensus through requesting users to show ownership of a certain amount of currency.
