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.
Syscoin is “a global network, a distributed ledger, a decentralized database and a blockchain. It is also a cryptocurrency, an altcoin, a digital currency and a tradable token.” Originally launched in late 2014 and created through a Bitcoin fork, the current version brings us to Syscoin 2.1 and has an algorithm that allows it to be merge-mined with Bitcoin. Merge mining is simply the ability for miners to simultaneously mine two different cryptocurrencies based on the same algorithm. The project attempts to remove the middleman and put money directly back into merchants/consumers hands, eliminating hefty fees currently charged by big corporations like Amazon and eBay. To facilitate near-zero fee transactions, you can use its native cryptocurrency, Syscoin (SYS), to pay for goods on the marketplace. However, you can also pay using alternate cryptocurrencies such as Bitcoin or Zcash. Syscoin is led by a team of developers and was created by its current core developer, Sebastian Schepis. According to Proof of Developer, a website that verifies, evaluates, and ranks developer teams, Syscoin received 5 stars in 2014. Blockchain Foundry maintains Syscoin as its flagship product, with a mission to “disrupt markets by leveraging the potential of blockchain technology”. In March of 2017, Blockchain Foundry partnered with the Microsoft Azure ecosystem and is one of the founding members of the Digital Identity Foundation (DIF). Other founding members of the DIF include the likes of corporate giants such as Microsoft, Accenture, ConsenSys, and more. Syscoin’s blockchain delivers faster speeds along with lower transaction fees than its predecessor, Bitcoin. It can support 750 tps, and with the upcoming masternode release, it will support more than 300,000 tps. For now, it’s one of the cheapest cryptocurrencies regarding transaction fees (behind zero-fee transaction cryptocurrencies such as NEO and NANO), even cheaper than XRP.' Some of the features highlighted on the SysCoin website includes :- 1. Buy/Selling goods on the blockchain 2. Brokerage on the blockchain 3. Issue and trade certificates on the blockchain 4.
