'DigitalNote describes itself as a decentralized Proof-of-Work(bmw512)/Proof-of-Stake(echo512) hybrid blockchain with fast, untraceable transactions and encrypted messaging features. The network is reportedly resistant to 51% attacks via its VRX v3.0 technology and it is mobile-ready with lightweight wallet functionality. A masternode network reportedly enhances untraceability and provides incentive for users to secure the network, whilst enabling fast private transactions and P2P messaging that are difficult to trace or censor. Miners and stakers are encouraged to participate via network fee payouts, facilitating consistent block generation and a fast network. DigitalNote was originally released as ''duckNote'' by an anonymous individual or group of individuals under the pseudonym ''dNote'' in 2014. Over the years more advancements were added to the protocol, with each major upgrade rebranding the name of the protocol (first ''DarkNote'' and then ultimately ''DigitalNote''). Much like Bitcoin's ''Satoshi Nakamoto'', the original founder(s) vanished in 2017, leaving the open source code to be updated by a community team who have since continued development.'
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.
