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.
OpenChat is an open source organization founded by Google former employees. The main definition of blockchain based chat protocol Bimp. In the traditional XMPP protocol adds a digital asset can be transmitted in each IM function. BeeChat will give its full support to all OpenChat projects. BeeChat is a decentralized application that runs under the protocol framework provided by OpenChat. BeeChat uses financial incentives to bring other digital services and applications into the decentralized OpenChat ecosystem in the form of communications & wallets. The OpenChat Reward Engine will provide ChatCoin as a natural incentive for digital service providers. In addition to ensuring common ethics and legitimacy of content and transactions, the ecosystem does not impose any unnecessary restrictions or charges on monetization strategies, which in turn encourages new partners to join the initiative. BeeChat now has hundreds of millions of users around the world, and BeeChat is committed to providing full support for the development of OpenChat, and OpenChat will continue to conduct a full range of decentralized research using BeeChat's support.
