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.
The VideoCoin Network is a decentralized video infrastructure platform redefining the process for creating, storing, and distributing digital video content. The project is led by the VideoCoin Development Association Ltd. (Cayman Islands). Powered by a large-scale, distributed video infrastructure, the VideoCoin Network will usher in 'the new cloud,' by marshaling underutilized computing resources from around the world to revolutionize video services with blockchain technology. The VideoCoin Network ecosystem will lower costs by deploying unused compute resources and peer-to-peer video distribution, enabling a new generation of applications via open APIs and open source-based development, with increased privacy using decentralized, end-to-end encryption. The VideoCoin Network is the first blockchain project to integrate a third party fiat payment processor, underpinned by a consortium of banks. The model is optimized to enhance the utility of the VID as a reputational staking token that powers the network and ensures that the most qualified network operators are serving customer needs.
