PAX Gold (PAXG) is an asset-backed token where one token represents one fine troy ounce of a London Good Delivery gold bar, stored in professional vault facilities. Anyone who owns PAXG has ownership rights to that gold under the custody of Paxos Trust Company. Since PAXG represents physical gold, its value is tied directly to the real-time market value of that physical gold. PAXG gives customers the benefits of actual physical ownership of specific gold bars with the speed and mobility of a digital asset. Customers are able to have fractional ownership of physical bars. On the Paxos platform, customers can convert their tokens to allocated gold, unallocated gold, or fiat currency (and vice versa) quickly and efficiently, reducing their exposure to settlement risk. PAXG is also available for trading on Paxos’ itBit exchange. PAXG will also be available on other crypto-asset exchanges, wallets, lending platforms and elsewhere within the crypto ecosystem. At any time, PAXG holders can lookup the serial number, value and physical characteristics of their vaulted gold just by entering their Ethereum wallet address on the PAXG lookup tool on Paxos.com/paxgold.
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.
