Aeon is a mobile-friendly, lightweight privacy coin. Similar to the way that Litecoin is a lighter supplement to Bitcoin, you can look at Aeon as Monero’s little brother. The Monero community is wholly focused on privacy and anonymity for the end-user. This focus has its perks but has caused the coin to fall behind from a usability standpoint. Aeon builds upon Monero’s CryptoNote hash while adding some lightweight functionality of its own. Aeon is the lighter, faster version of Monero. Although both projects share the same underlying privacy protocol, CryptoNote, Aeon is striving to be more accessible. The project is doing so by implementing a lightweight mining algorithm, smaller blockchain, and optional anonymity. As Monero grows, Aeon could very well grow with it. While you would use Monero for transactions in which you want to assure privacy, you may find Aeon to be a suitable substitute for day-to-day exchanges in which guaranteed anonymity isn’t as important.
Myriadcoin is the first coin to implement five different Proof-of-Work hashing alrogithm in the same coin, namely Scypt, SHA256D, Qubit, Skein and Groestl. This multiple hashing algorithm serves to make mining fairer and encourage even distribution. Each algorithm has the same chance of solving the next block and has its own independent difficulty while using the same difficulty adjustment method. Each algorithm aims for a block generation time of 2.5 minutes. Any existing CPU,GPU and ASIC miners can be used to mine Myriadcoin. Over the five algorithms, a block should be found on average every 30 seconds. Every 967680 blocks, the block reward halves in order to reduce inflation. Difficulty is adjusted after every block. Myriadcoin was launched on 23 February 2014.
