Auroracoin is a decentralised, peer-to-peer, and secure cryptocurrency released as an alternative to the Icelandic Króna to bypass governmental restrictions associated with the national fiat currency. It was launched with the aim of becoming the ‘official’ cryptocurrency of Iceland. AUR was a pioneer in the area of country-specific cryptocurrencies. AUR was launched on the 25th of January, 2014, by an anonymous developer who went by the pseudonym of Baldur Friggjar Óðinsson. It was originally based on Litecoin, using the Scrypt algorithm with a Proof of Work mechanism, but was later updated to use a multi-algorithm architecture in 2016, forked from DigiByte. Auroracoin uses the PoW consensus mechanism, which utilises device hashing power to solve a complex mathematical problem in order to authenticate a transaction proposed to be stored in the blockchain. The difficulty of solving the problem ensures that authenticating forged transactions is very difficult unless the attacker owns an impractically large chunk of the network’s total hashing power. AUR is one of the only cryptocurrencies to use a combination of five different hashing algorithms, namely Grøstl, Qubit, scrypt, SHA-256, and Skein. While initially very popular, Auroracoin has seen little to no activity for a while, with poor marketing, and frequent dev team changes. Reasons for little growth have been various, from slow adoption in Iceland, to developers leaving and joining the project midway. However, it is expected to not go lower than the recent low, and might see a rise as AUR plans to launch a more aggressive marketing campaign in Iceland to promote the coin among the masses. Unlike most other altcoins, Auroracoin has made extensive changes to the original codebase. It has introduced security measures such as Automatic checkpointing, and protecting against known flaws present in the BTC blockchain, such as 51% block replacement attacks.
Metaverse is a leading public blockchain based in China. Designed to facilitate low-cost, convenient transfer of digitized personal data and assets with unprecedented security and privacy, Metaverse aims to revolutionize the way financial services and transactions are processed, and to improve outdated and inefficient identity verification services with a network of Digital Assets, Digital Identities, and Oracle intermediaries. Metaverse is an open-source public blockchain that provides digital assets, digital identities and Oracles as a foundational infrastructure for social and enterprise needs. Through Blockchain-as-a-Service (BaaS), we make convenient, secure digital financial services accessible to all applications at virtually no cost. Founded in 2016, Metaverse went live in February of 2017. We strongly believe that blockchain technology is the catalyst for a better future - the New Reality. The concept is building a network of smart properties and a decentralized exchange for a smart and secure infrastructure. It already has dApps like Supernova running on the mainnet, and cross-chain compatibility with ERC-20 tokens is right around the corner in the project’s development roadmap. Metaverse ETP is used to value or collateralize smart contracts on the Metaverse blockchain network. It’s also used to pay transaction/gas fees. ETP is generated through PoW mining. It’ll soon introduce a PoS model to the platform. Metaverse supports digital identities, assets, oracles, and exchanges, making it a versatile blockchain 3.0 solution. Its development ecosystem already has a gold-backed crypto trading app on the market. Many more are in development for release before 2020. ETP is tradeable on a wide array of crypto exchanges. Its current PoW model will soon be supplemented by a PoS hybrid.'
