FYI, long post warning.
On December 2012, The CryptoNote whitepaper was published and was set out to create a new foundation of cryptocurrencies that would address the privacy and distribution issues that has plagued bitcoin since its inception. Unlike Bitcoin, CryptoNote's transactions cannot be traced through the blockchain that reveals who is the sender or receiver. The approximate amount of a transaction can be known, but the origin, destination, or actual amount cannot be learned. CryptoNote also uses a memory bound function named CryptoNight, which cannot be easily mined with a Application Specific Integrated Circuit (ASIC) miners. Combined with the fact that all CryptoNote currencies are not bitcoin forks, this allows a more equal form of distribution and decentralization.
Because the CryptoNote Foundation encourages developers to clone the technology, Multiple coin experimentations such as transaction confirmation time, total number of coins and proof-of-work logic are tested and developed. Because of these experiments, The CryptoNote platform are in several cryptocurrencies in various stages of development, support and usage. In this article, I will be explaining the most common CryptoNote coins and what sets each of them uniquely apart. Each of these coins will be introduced in order of their release date.
Bytecoin (BCN) - Active
Monero (XMR) - Active
DigitalNote (XDN) - Active
QuazarCoin (QCN) - InActive
FantomCoin (FCN) - InActive
The first merged mining Cryptnote coin was released in 2014 and was a very interesting experiment. The ability to mine both Fantomcoin as well as Bytecoin, Monero or even Quazarcoin shows how interconnected they can be together and allows miners to diversify their altcoin holdings without mining each coin separately. Unfortunately, the difficulty ramp increased greatly considering few people have no reason not to mine this in addition to their favorites. And just like Quazarcoin, developer communication appeared to stop at early 2015 but the community continues to quietly mine and trade. In August 2017, the DigitalNote developers hosted Fantomcoin's GUI wallet on their github depository meaning that there may be more just an illusion that this coin is dead.
Anonymous Electronic Online coiN (AEON) - Active
Not Really. Because it was an open-source project, the community rallied and carried the project forward. As time passed, AEON evolved to become a lighter and faster version of Monero. They even allow the users the option to use a traceable transfer for non-sensitive transactions that is faster and lower in fees making it ideal for mobile platforms. As user FabledWyrd stated "I believe there were people who said they would like to buy their house with Monero and their coffee with Aeon."
MonetaVerde (MCN) - Dead
DashCoin (DSH) - ?Active?
From getting it confused with DASH to the involuntary fork of Dashcoin Minergate, DashCoin is perhaps the most cryptic of cryptocurrencies. Until these confusions are resolved one by one, it would be hard to explain its value proposition when its identity itself is in question.
Infinium-8 (Inf8) - Dead
In July 2014, Infinium-8 was the latest CryptoNote coin that released to the world. Much like MonetaVerde, Infinium-8's block reward increasing together with its difficulty to mine that encouraged fairer distribution. With an infinite supply of coins, this provided miners plenty of opportunities to mine out their fortunes. However, the big difference is the lack of merge mining which is strange considering if this was a copy, it should at least bring another new feature which it does not. Unfortunately, with no exchanges willing to accept INF8 and the fear of infinite supply that could drives inflation, this coin is effectively dead as of August 2014.
Conclusion
While there were many other failed CryptoNote projects, the developers had the foresight that allowed others to easily create, modify and release their version of the ideal coin. This level of collaboration shows how some worked together, some worked apart and ideally the best of ideas will rise to the top. I hope this article shed some light on not only the CryptoNote family but also their unique value propositions. Please upvote and subscribe. Thank You!
