Gulden is a second-generation peer-to-peer cryptocurrency which was created to provide a secure, simple and fast method of performing financial transactions between private individuals, customers & service providers and also corporate entities. Like many recent cryptocurrencies, the primary design criteria were to improve the security and usability of the currency and its underlying transaction authorisation technology (when compared to the original cryptocurrency - Bitcoin). The purpose of these changes was to simplify use and increase its adoption as a convenient, cheap and safe form of payment. The original initiative for this currency came from Rijk Plasman with the first working implementation released on the 4th April 2014. Initially called the “Gulden coin”, this was subsequently abbreviated in October 2015 to “Gulden”. The name Gulden comes from the German and Dutch term for “gold coin” and is the Dutch name of the Dutch guilder, the pre-euro currency of the Netherlands. Gulden Coin is the currency that enables the user to pay safely, conveniently and quickly. Moreover, it is a lucrative investment opportunity at the moment, considering that since entering the market in 2016 the developers have increased to a market capital of 39,883,259 USD with about 800,000 USD. The model of making cryptocurrencies accessible to ordinary consumers in the future holds enormous potential in the fintech sector.
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.
