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.
Mastercoin / Omni is a digital currency built on top of the Bitcoin blockchain. Its features include the development of a decentralised exchange and the implementation of smart property and savings wallet. The Master Protocol facilitates the creation and trading of smart properties and user currencies as well as other types of smart contracts. Mastercoin enables the Bitcoin eco-system to become more decentralized. The Mastercoin project was launched on 31 July 2013 with a one-month long fundraiser. Those interested in obtaining Mastercoin may send bitcoin to an 'Exodus Address' where the funds collected would be used to fund the development of Mastercoin. Around 500 people invested in Mastercoin sending roughly 5000 bitcoins to the Mastercoin project.
