Coin Report #8: Arionum

N.B: This Coin Report has been selected by the readers of the blog, with Arionum winning the poll with 41% of  the ~2,300 votes. Congratulations!

Welcome to the eighth Coin Report. In today’s report, I will be assessing the fundamental and technical strengths and weaknesses of Arionum. This will comprise of an analysis of a number of significant metrics, an evaluation of the project’s community and development and an overview of its price-history. The report will conclude with a grading out of 10. I hope you enjoy the read!


Having only recently completed a Coin Report on Bismuth, I found it rather amusing that this next one – as selected by the community – will be on Arionum, for reasons that will become evident as the report progresses. In short, both projects are unique, first-of-their-kind cryptocurrencies, written from scratch in their respective languages. As such, I feel as though chance has given us a good opportunity for a true and thorough cross-comparison. This report will follow the regular template in its composition, but it would be negligent not to draw comparisons where appropriate.

As mentioned above, Arionum is one of those rare cryptocurrencies that is built from the ground up, and thus I was quite excited to find that it had won the community poll. That being said, aside from this singular fact, I knew relatively little about the project prior to conducting my research for this report. Having now completed this research, there is much to be excited by but certainly areas where improvement is required; eerily enough, these areas correspond with those of Bismuth.

I hope this report will prove objective where it must be and fair on more subjective matters. For those who’d like to learn a little more about Arionum prior to reading this report, here are some primary links:



Name: Arionum

Ticker: ARO

Algorithm: Argon2i + SHA512

Sector: PHP Blockchain Platform

Exchanges: Mercatox

Arionum was launched in January 2018 – oddly enough around the time of the market peak – with no premine and no ICO. It was written from scratch in PHP; the first cryptocurrency of its kind. The coin operates using a Proof-of-Work consensus mechanism on a combined Argon2i + SHA512 hashing algorithm. It also operates using masternodes with a collateral of 100,000 ARO. The Proof-of-Work phase is expected to last ~8 years from launch, with the block reward beginning at 1,000 ARO and decreasing by 10 ARO every 10800 blocks. We’ll dig into supply emission and the block reward schedule a little later.

Of all the coins I have written reports on, Arionum has the least available price-history, with data going back only four months – to the beginning of August. Despite that, Arionum has experienced two short market cycles, setting an all-time high of 734 satoshis ($0.048) at the end of October. Price has since dropped off, setting a local low of 236 satoshis late in November. More on this in the Technical section.

Arionum, as a project, is primarily concerned with streamlining the development process for those familiar with PHP, relative to other programming languages. Further to that, and more applicable to the layman user, Arionum seeks to drastically reduce transaction costs and improve upon the scalability issues found in Bitcoin. Lastly, its future is concerned with developing a graphical interface for asset creation, allowing less technical users to develop their own digital assets and currencies.

That should suffice as a general overview of the project; onto some metrics:

Metric Analysis:

Below are listed a number of important metrics, all of which are accurate as of 13th December 2018. For anyone reading this who has yet to read a Coin Report, it might be worth reading this section of the first report, where any potentially unfamiliar terms are explained. For any terms or metrics specific to this post, I will provide explanations besides the figures.

Inactive Address Count in Top 20 (30 Days of No Activity): 10


There’s a mountain of material to cover here, and I’ll begin with the General metrics, before moving on to sequentially unpack the rest.

Firstly, let’s take a look at the price-and-volume-related metrics: Arionum is currently trading at a Network Value (here meaning price x circulating supply) of $1.341mn, or 394.88 BTC. This would place it in the lower-midcap range of altcoins. The Average Network Value for the past 30 days is a little lower at $1.048mn, despite the price of Bitcoin decreasing significantly in the past month, indicating that Arionum has been faring well against Bitcoin recently, as we shall discover a little later. The Exchange Volume for the past 24 hours comes in at $67,581, whilst Average Exchange Volume is ~$49k. This gives Arionum an Exchange Volume-to-Network Value of 5.04%, and an Average EVNV of 4.67%. This is very impressive. In prior reports, I have mentioned that I tend to look for altcoins with 1% or greater for these metrics as a sign of significant interest, but current market conditions have made such scenarios sparse. Well, Arionum seems to have plenty of interest despite such conditions and despite the fact that it is only traded on one exchange: Mercatox. Further, Arionum actually beats out any coin previously reported on with regards to this particular metric, with Stakenet coming in second place with 2.33% EVNV and 1.48% Average EVNV. As I say, this is a promising start.

The next point-of-interest from the General metrics is Liquidity and the metrics relating to supply available on exchanges: Arionum has Liquidity of around 0.15% of the Network Value, which places it in the middle of the pack relative to other coins reported on. Further, there is a little over 2.1mn ARO available for purchase in the Mercatox orderbooks, which equates to 1.85% of the circulating supply. Of the four coins I have previously calculated this metric for, Arionum has less of the circulating supply available than three of them, suggesting that there is a relatively high inclination towards holding ARO. The masternode returns may be a contributing factor to this, as I’ll highlight shortly.

A final point to highlight from the General subsection before we move onto Supply Emission & Inflation: there is zero premine, which I always like to see.

Now, calculating supply emission and inflation metrics is fairly straightforward for Arionum, as it has a simple block reward schedule. Using an average block time of 4 minutes, a current block reward of 880 ARO and a decreasing block reward of 10 ARO every 10800 blocks, the supply emission for the next 365 days works out at ~107,838,480 ARO, or 367.73 BTC at current prices. This equates to an annual inflation rate of 93.12%. Without doubt, this is rather high and a little worrying for those of us who are potentially looking to turn a profit on a position in Arionum. In fact, this is the highest inflation rate for any coin I’ve reported on.

But how does the supply emission relate to the volume that Arionum is generally trading? Well, with an annual supply emission of 367.73 BTC at current prices, average daily supply emission works out at almost exactly 1 BTC, or ~$3398. Arionum’s trading volume (Exchange Volume) for the past 24 hours is ~1988% greater than this supply emission, and its Average EVNV is ~1442% greater. This is ample trading volume to cover the supply being minted daily, and thus current prices should be sustainable if current levels of volume persist. Thus, any decrease in price should generally be attributed to either smart-money distribution or weak-hand distribution, rather than to miners dumping their rewards, and this could be more precisely determined using rich-list analysis. This is also roughly 5 times greater volume-to-supply emission than I found in Bismuth, despite Bismuth having half the annual inflation rate of Arionum.

Moving onto masternodes, Arionum offers an annual return on its masternodes of 83.34%, calculated using figures for current active masternodes, annual supply emission and the percentage of the block reward that is distributed to masternodes. This is a very high return, and unsurprising given the high inflation. It is actually the highest annual ROI of any masternode from previous reports.

Next, let us consider the strength of the Arionum masternode network: with 427 active masternodes and a collateral size of 100,000 ARO, this gives us 42.7mn ARO locked in masternodes. This equates to a Masternode Network Value of $494,832, which is 36.87% of the Arionum Network Value. This is indicative of a moderately strong masternode network, as it is stronger than the masternode network of Bismuth and Stakenet but weaker than Bulwark and ALQO.

Finally, let’s take a look at Distribution:

As Arionum states in its whitepaper, “the goal is to be… democratically spread across non-professional miners.” In short, decentralisation is key, and this seems to be a point of strength for the project. Discounting the richest address, which is owned by Mercatox and contains ~13mn ARO, the top 10 richest addresses control 12.91% of the supply. The top 20 control 17.36% of the supply and the top 100 control 30.03%. This is slightly more decentralised distribution than Bismuth, which (discounting its richest address, which is owned by Cryptopia) had the top 10 controlling 16.44% of the supply.

Let’s dive a little deeper into the Arionum rich-list. 10 of the top 20 addresses have been inactive for the past 30 days, whilst the 4th, 10th, 13th, 17th and 19th-richest addresses are in active accumulation. Only the 11th-richest is distributing at current prices and the remaining addresses have shown negligible activity recently. This shows that the vast majority of the richest holders are either accumulating or holding at present, which is a good sign.

That concludes this section on metrics. Let’s dissect the Arionum community:


There are two primary aspects of community analysis: social media presence and Bitcointalk threads. I’ll begin with the former before moving on to the latter.

Social Media:

Concerning social media presence, there are four main platforms to examine: Twitter, Facebook, Telegram and Discord.

Arionum is present on all four platforms. To begin, let’s look at the various social metrics that I calculated from the Arionum Twitter and Facebook accounts:

Twitter Followers: 1994

Tweets: 174

Average Twitter Engagement: 2.1%

Facebook Likes: 36

Facebook Posts (30-Day): 0

Average Facebook Engagement: N/A

As usual, I will be using RivalIQ‘s social benchmark report for evaluation purposes.

Firstly, I’d like to point out that despite Arionum having a Facebook page, it seems to be out of use, with no posts showing since April. This isn’t great, as it suggests that the team thought Facebook important enough to create a page but not important enough to spend the time it takes to maintain it.

That being said, Arionum does seem to have some solid engagement on Twitter. It has quite a small audience of just under 2,000 followers (relative to Bismuth’s ~7k followers) and the team are relatively inactive with less tweets than any other project I’ve written a report on besides Dero. But, their Average Twitter Engagement rate is 2.1%, which is stronger than all except Dero, funnily enough. The engagement level is roughly 3x that of Bismuth.

Further, using the RivalIQ report, we can see that Arionum has 45.65x more engagement than the average across all industries, and over 161x greater engagement than the Media industry. The engagement is certainly promising, but the audience is small.

Now, moving onto Discord, Arionum has 3023 members in its group, which is slightly larger than Bismuth’s group. 53 new members joined in the past week, which equates to 1.75% weekly growth. There are plenty of channels available under relevant subsections for all manner of topics, which I like to see as it ensures accessibility for newer users. Further, there is an FAQ channel with all resources clearly linked.

With regards to the content of the group, Announcements seems to be updated more regularly this month than previously, with an update every two or three days in December but only one update in November. Development is fairly active with some discussion taking place on a daily basis, most recently concerning a phishing incident that occured a few days ago and led to some users of the web wallet and Android wallet losing their funds. Suggestions is currently on the topic of Ledger integration for Arionum, which would be great to see. I found very little of interest in Marketing, which may explain the smaller audience across platforms for the project. There is a lot of action occuring in the OTC channels; this makes sense given that there is only one listed exchange.

As usual, General is the most popular channel, with near-constant conversation taking place. Of late, this revolves around the phishing incident, understandably. There is a little talk on the need for new exchange listings; a listing on Cryptopia is confirmed. Much of the back-and-forth is currently about convenience versus security, and many feel as though the team’s decision to disable the affected wallets is a step backwards for the project as it dramatically reduces the potential userbase to only those with some degree of technical proficiency, given the PHP codebase. I’m inclined to agree, though there is a GUI Lightwallet available for Windows users. There is also some degree of backlash arising around communication and the team not using the community to its full capacity to assist with the project. The positive here is that the community certainly seems willing and engaged. Finally, there is some talk about a cross-platform wallet currently in development for Mac, Windows, Linux, iOS and Android, which sounds promising. Overall, the group is highly active but, at present, in minor crisis.

Unlike its engaged Discord group and Twitter account, Arionum’s Telegram group follows the footsteps of its Facebook page, with 392 members but only a handful of daily messages. In general, the Telegram doesn’t seem to be used for much besides the odd support query. Strangely enough, this is exactly what I found to be the case with Bismuth – a strong Discord and a neglected Telegram.


The Arionum BitcoinTalk thread was created on January 8th, 2018, and has since generated 2175 posts spanning 109 pages in 339 days, giving an average of 6.4 posts per day. However, in the past 90 days, the thread has had 183 posts via ~40 individual posters, giving an average of a little over 2 posts per day, suggesting that activity has died down of late. That being said, 183 posts in the past 3 months is still more activity than most of the coins I’ve previously reported on.

That concludes the section on Community. Onto Development:


For the following Development analysis, I will be evaluating project leadership, the website, the roadmap, the whitepaper, the wallets and finally providing a general overview:

Project Leadership:

There is no clear information on the team displayed on the website, and there are 4 contributors to the Github. An FAQ on the forum shows that there are 3 core developers, with 27 years of programming experience between them, specialising in PHP and Linux. There is very little expertise in marketing and none in project management. I would like to see this balanced out a little; perhaps adding a marketing specialist or an operations manager would assist in growing the userbase.


The website is fairly well designed and branded, and it is informative for new users, with a thorough overview of the project displayed and relevant resources linked. There is also a dedicated forum, which is a plus. That being said, it looks a little amateurish relative to the websites of other cryptocurrencies (a problem I also found with Bismuth’s website). Further, there is no clear link to the Arionum wallets. In general, I’d like to see a redesign for the website and a regularly updated blog.

The block explorer, in contrast, is fantastic. It is highly functional with a plethora of useful features and a visually appealing interface. More of this, please.


There is no roadmap to be found on the website or the BitcoinTalk thread, which is highly disappointing.

Update: I missed that there is a text-based roadmap in the BitcoinTalk announcement. Everything besides the payment processor and the assets system has been achieved.


The Arionum whitepaper is more like a lightpaper, as it is only 2 pages in length. I know I like my whitepapers concise rather than lengthy but this might be a little too brief. The whitepaper is in need of proof-reading and makes little mention of the future direction of the project; of its goals and aims;  or of its unique features. Its redeeming quality is that it does talk briefly about Arionum’s advantages over Bitcoin, with regards to dynamic block sizes, fixed fees and a CPU-optimised hashing algorithm. It also mentions that Arionum will be developing a graphical interface for asset creation, in an attempt to alleviate the problems faced by non-technical users in creating their own digital assets and currencies. There needs to be much more detail on such an interesting aspect of development such as this.

Overall: again, rather disappointing. It seems as though the resources and platforms that are most useful in growing a userbase (social media, roadmap + whitepaper) are neglected by the Arionum team.


With regards to wallets, there is a CLI for Windows, Mac and Linux, as well as a GUI Lightwallet for Windows and Mac, a web wallet and an Android wallet. The latter two are currently disabled due to the phishing incident.


Generally, it is quite difficult to judge the development progress of the project without a corresponding roadmap or a detailed whitepaper. Obviously, the stand-out achievement is writing the blockchain from scratch in PHP; a first for any cryptocurrency. But, since this point, there doesn’t seem to have been any stand-out development achievements, and, if there are, they’re well-hidden.

Looking forward, the graphical interface for asset creation piques my interest but, again, there must be more detail available for those that come across Arionum in order to grab their attention and grow the coin’s userbase.


Despite having only four months of available price-history, the Arionum chart exhibits two short-term market cycles. Price initially formed a local high at ~700 satoshis before dropping off to form its all-time low at 77 satoshis, completing its first mini market cycle. Price then formed a short-term accumulation range between 180 and 230 satoshis before breaking out, climbing above the pivot are around 330 satoshis, all the way to new all-time highs at 735 satoshis. We have since seen a similar drop-off to that of the first cycle, though this time price has formed a higher-low around 230 satoshis – the breakout level from the previous accumulation range. Minor levels of prior resistance continue become new support levels as ARO/BTC has climbed for the past couple of weeks, with price now sitting within that pivot area.

A swing trade could possibly be available here, with ~30% of downside if a soft stop is placed at that local swing-low ~230 satoshis. There is ~120% of upside potential to the all-time high, giving a reward-to-risk of 4:1. However, for those looking for more of a long-term position, buying below this pivot area has generally been rewarded and volume has continued to steadily rise for the past few months. Inflation is naturally a worry, but the trade volume is certainly sufficient to sustain current prices.


This report is now approaching 4,000 words, and it is time to draw it to a close.

My final grading for Arionum is 6 out of 10. It is quite clear that there is promise here, not only with regards to the project being written from scratch and being the first of its kind, but also in the engagement shown on Twitter and in the Discord group, as well as the strength shown in many of the metrics. But there is a lot to be improved on.

Lastly, here is a link to a Google Sheets file with any significant data from previous reports compiled for cross-comparative purposes. I will keep this updated as I continue to write these reports.
