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.
Leveraging on blockchain technology, we develop a decentralized, low-cost, and private AI computing platform and also provide perfect peripheral products. The DeepBrain Chain token is traded via smart contract based on NEO, and our token is called DeepBrain Coin (DBC), and the mining node is encouraged according to the incentive system designed by the smart contract. The DeepBrain Chain is a decentralized neural network. The calculating demands of enterprises will be distributed to countless mining nodes all over the world. It will get DBC as a return when the nodes deployed computational mirror image successfully and the GAS fee each enterprise need to pay is far less than the intrinsic fee. The DeepBrain Chain is also a secure data trading platform. Both of the trading parties don’t need to worry about data leakage or reselling. Blockchain technology is used to realize the separation of data ownership and usage rights drastically. Thus, the value of data will be promoted greatly. “the Uber in AI computing”
