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.
IONC is the official token of IONChain. It can be utilized by different participants in IONChain ecosystem. The maximum supply of IONC is 800 million. It is going to be released gradually for 20 years. After 20 years, the administrative committee elected by IONChain users using the consensus mechanism will decide whether to re-issue IONC tokens based on the amount of on-chain devices, amount of data being processed and the overall level of IONC abundance in the ecosystem. IoT devices and data access constitute the core parts of IONChain ecosystem, therefore IONC token is going to be used to reward devices and data providers. The yearly supply of IONC tokens increases along with the demand for data access. However, the upper limit is pre-set. IONC token is an indispensable part of the IONChain system as it is a single most crucial part of its ecIONChain aims to solve a wide range of the current problems of IoT networks in terms of data security, data circulation, data sharing and data transactions, thus enhancing the efficiency of the whole IoT ecosystem. IONChain introduces the concept of “One Device, One Coin, One Code” which facilitates the integration of IoT devices with the IONChain blockchain network. With the use of Edge Computing technology, it enables every device on the IoT network to be utilized as a mining machine, making every IoT device that uses IONChain subject to mining rewards. Owing to the use of blockchain technology, the data source will always be reliable and verifiable on the IONChain network. Furthermore, the value ofthe data is quantified and data transfers are fast and secured. This makes it easier for IoT standards to emerge, unlocks a plethora of new IoT application scenarios and boosts the whole industry to enter the next level of development.
