Haven is an untraceable cryptocurrency with a mix of standard market pricing and stable fiat value storage without an unsustainable peg or asset backing. It achieves this with a built in on-chain smart contract that controls the minting and burning of coins in a network of cryptographically unknown supply to facilitate value for users that choose to send their coins to offshore storage contracts while allowing everyone else to be exposed to the natural price movements of the currency. Offshore Storage Offshore Storage is Haven's built in smart contract/protocol that powers the stable value storage. In short, sending Haven to offshore storage (burning) records a reference on the blockchain to the current fiat value which can be restored later back into Haven by minting new coins to the tune of the current fiat value. The key use cases for offshore contracts are: Point of sales/payment gateway systems where goods can be bought with Haven and stores can immediately lock the fiat value in to protect from price fluctuations. This has the added benefit of keeping the stores business and income completely hidden on the blockchain as neither their wallet address or amounts are revealed. Storing large amount of money outside of the traditional banking system. Privacy focused cryptos are perfect for this but without a reliable way to maintain value through fluctuations the process of holding could be costly. Sending Haven offshore quite literally, makes money disappear until you want it back at which point the value remains intact. Untraceable | Hidden | Decentralized Haven uses ring signatures, ring confidential transactions and stealth addresses meaning payments cannot be tracked or linked back to any user. Wallet addresses and transaction amounts are completely obfuscated on the Haven blockchain making all activity invisible. The Haven Protocol is decentralized and open source meaning no central control over the network. Nothing is censored.
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.
