Coin-a-Year: Nyancoin

Hello cryptocurrency lovers! Welcome to Coin-a-Year, the laziest series yet in the Coin-a-Day publishing empire. This year's coin is Nyancoin (NYAN). I originally covered Nyancoin in an article here in /cryptocurrency published January 4th, 2015.
Without (much) further ado, I'm going to include the original report next, unmodified. This is unlike my Coin-a-Week series, where I use strikeout and update in-text. Because this is going to be a longer update, I'll just make all further comments and updates below, just realize that all information below is as of January 4th, 2015 and thus is more than a year out of date as of posting now, at the end of February 2016.
Since I use horizontal rules as internal dividers in the original post, I'll use a double horizontal rule to divide the original text from this prelude and the following update.

• Innovation or special feature: First officially licensed cryptocurrency (from Nyancat) [2]; "zombie"-coin [11]
Description / Community:
So you're probably wondering why in the world we're talking about a coin which has been declared dead and already written off. I actually first selected this coin to illustrate a "deadcoin", but the more I dug into it, the more I was amazed at the shambles I discovered. I am combining the description and community sections for this coin, because the community (or lack thereof) is the central issue for Nyancoin.
Substantially all, if not literally all, of the original infrastructure is gone. From the announcement post, the original website has expired. The nyan.cat site itself survives, but has no reference to the coin. The github repo remains, but then there was never much changed from the bitcoin/litecoin original. In fact, the COPYING file doesn't even list "Nyancoin Developers". None of the original nodes seem to be running anymore. @Nyan_Coin hasn't tweeted since July 6th. And that was just to announce posting an admittedly cute picture to facebook which makes a claim for a future which seems never to have developed. Of the original 15 pools, I think all are dead except p2pool, for which at least one node still supports NYAN. The original blockchain explorer, nyancha.in, is still running. The faucet is dead or broken. The original exchanges no longer list it (two of the three having died; SwissCEX having ended its trading as of the first of this year). And so forth.
And yet:

I'm not dead! I'm getting better!

No you're not, you'll be stone dead in a moment.
[Of course, that scene finishes with knocking out the "recovering" patient so he can be taken away...not to mention the absurdity of including Monty Python in a financial article, but moving right along.]
There is still just enough left to Nyancoin to keep it twitching, even if it is on life-support. Whether it's an individual node or whether it's a pool, there are blocks being produced at a steady rate as intended. Transactions are being processed. There is still a market. There is still a block explorer. And there is a dev. It is like a case study in the absolute minimum necessary to keep a coin alive. The most likely outcome is almost certainly a final collapse when one critical piece or another of the infrastructure goes away. And yet in the meantime, a person can own a million NYAN for $8 [12], and then move this coin quickly and easy, albeit with no particular external demand. It's like the world's most hyped testnet.
I think this case presents an interesting example of what happens to an altcoin when its initial support dries up. NYAN coin is more fortunate than some, actually, as there are some where there are no longer any nodes running it nor the original announcement thread (in fact, there was actually a second Nyancoin launched around the same time. But it died hard and its original announcement thread was deleted and at this point I would have no idea how to access it; so "Nyancoin" thus illustrates how hard a coin can die (Nyancoin 2) as well as how it can hang around despite being proclaimed dead, with far more justification behind that pronouncement than there has been for bitcoin (NYAN) ).

[2] https://bitcointalk.org/index.php?topic=402085.0 Regarding the premine, it's unclear to me where this money is now, since the original poster hasn't been active on BCT since May and the original site is down. However, given that it's only 1%, and about $25 in value right now, there seem to be more significant concerns for NYAN.
[3] http://nyancha.in/chain/Nyancoin - Nyan blockchain explorer; blocks are somewhat inconsistent but somewhere around the 1 minute average
[4] There doesn't seem to be anything automatically doing these stats, so I did visual inspection on about 1500 blocks (about one day) excluding the block generation reward (~250k/day). Most blocks are otherwise empty. I counted about 24 transactions or so scrolling through, with an outlier around 300k NYAN and another around 100k NYAN. In total, about 500k NYAN, excluding the block rewards. This is very approximately $3-4.
[5] Nyancoin is a basically unmodified, slightly out-of-date bitcoin as far as code goes, and ignoring the change in block rate and total coin supply, as well as the difficulty retarget after every block. So for purposes of estimating maximum possible transaction throughput, I start with bitcoin's estimated 7 transactions per second, and multiply by 10 for having a block on average every minute rather than every 10 minutes. In any event, this limit is not likely to be reached in the foreseeable future.
[6] Like bitcoin, transaction fees appear to be optional in Nyancoin. Unlike bitcoin, there is almost no transaction volume, and coins tend to sit for a relatively long time before being moved. So zero-fee transactions appear to be the norm from looking at a couple transactions on the block explorer.
[7] I couldn't find one. See the disclosure section of this article: your humble correspondent is likely represented in some way on a top 100 if one were to be made or if one exists, despite not holding it directly, depending on how the exchange holds it.
[8] I could not find any other exchanges still listing Nyancoin. SwissCex appears to have disabled it as of a couple days ago. Cryptsy has a notice that the NYAN/BTC market will be closing, but its NYAN/LTC market appears strong.
[9] Essentially all of the original sites, pools, faucets, etc. are dead and there has been very little to replace it. There is basically a single node, or perhaps a very few, which are running the blockchain. However, there is a developer still trying to hold things together, maxvall_dev, maxvall on BCT. He is the last hope for the NYAN.
[10] https://bitcointalk.org/index.php?topic=597877.0 This is the thread where maxvall took over as dev, and it also discusses switching to PoS, which hasn't happened as far as I know.
[11] "zombie"-coin: Not to be confused with ZMB (my god, does it ever end?). This is my term to describe a coin which is "undead": by rights it should be dead. And yet it's still walking around and acting like it's alive. What is it? What's going on? It's quite debatable whether this gives it any special value, but I find it an interesting state, and it's why this was chosen for early coverage. There are plenty of actually popular and successful coins, and we will go onto covering more normal selections; we're looking for variety rather than repetition. But I think this is an interesting example for what can go wrong, and yet in the midst of that, how little it takes for a coin to survive. In fact, it's almost like an alternate history bitcoin to me; this shows the concept that "it was run on one computer before; it can be run on one computer again" to some extent. And there are even some strange pragmatic benefits as well, like having no competition for getting a transaction into a block and thus zero transaction fees.
[12] And, in fact, the author chose to do so today, spending about 0.03 BTC for about 1 million NYAN.

Giveaway
Instead of a challenge today, since NYAN has enough challenges, I decided I would give away 10,000 NYAN to at least the first ten people who ask for it. This still remains at my discretion, but honestly, if you really want, say, 50,000 NYAN and create four new accounts to do so, I'll probably be too amused to say no. I don't expect to get ten requests. If I get more, I'll probably still fulfill them, but as with everything else, this is left to my whim.
Donations and Disclosure
Okay, this is an important one today because of the tiny market here. I actually hold less USD value in NYAN than in BTC, DOGE, and PPC (although my value in PPC might be about equivalent actually), but I hold more of the total market in NYAN than any of those three. And I'll probably be buying more. So I have a conflict of interest in writing this article.
I am not providing financial advice and I do not make any recommendations of any sort on any matters. Make your own decisions; do your own research. Please, I do not want to hear about anyone doing anything "on my advice." I am not offering advice.
I personally hold just over 1 million NYAN on Cryptsy right now.
Perhaps it would be better if I didn't write any articles about anything I were invested inspeculating on, but I started this series for my own education to further my speculation, so unfortunately, dear reader, your needs come second to my own. tanstaafl; you get what you pay for, and I'm giving you my thoughts.
If by some strange quirk of fate you actually own NYAN and enjoyed this article and wished to donate some to me, K7Ho9HghBF6xWwS6JsepE6RAEPyAXbsQCV is mine (first non-empty account I've posted; transferred 1000 NYAN into here earlier from Cryptsy to test that the network and my wallet were actually working).
Thank you all for reading and commenting! I've already learned a lot from this process and I look forward to more!

I'll use alphabetic labeling for footnotes in the updates to avoid any confusion with the footnotes in the original. For simplicity, unchanged items, like the 337 million limit and the 1 minute will not be mentioned, and we'll start with the summary changes.
Updates:
Summary
  • ~263.7 million NYAN currently exist [a]
  • Current price: ~7 satoshi [b]
  • Current market cap: ~$8,000 [c]
  • Transaction rate: ~185 / last 24 hours; ~3,300,000 NYAN (~$100) [d]
  • Exchanges: Cryptopia [e]
  • Community: We're not quite dead yet; in fact, I think we're getting better! [f]
  • Code/Development: I have an early draft of NYAN2, but I'm about six months past my initial goal for having it available to use. Life/work/lack of build machine/procrastination. NYAN2 will be a rebase onto a modern LTC codebase which will soft fork to fix a current vulnerability to a fork bug. For now, the network still runs on the same code that it did when I wrote the first article.
Discussion
I'm going to consider the community first, since I pointed it out as the weakness and central topic in the last one, then talk about the technical situation briefly, and then review the financial results.
The community has been excellent, if I do say so myself. We've got working infrastructure going thanks to the contributions of many Nekonauts (see [f]). Some original Nekonauts have returned or at least popped in from time to time, and new ones like myself have found Nyancoin (I would say given what I wrote in the original, I was still a skeptic of it at that point. Not that skeptics can't be Nekonauts, but I think I'd put my conversion to the cult of nyan shortly after writing that, even though I was already a nillionaire then for the heck of it.)
While I do look forward to seeing the community continue to grow in future years and consider that important, I don't think the community is our weakest point any longer; I think it's now our strongest point. I've tried to encourage the community's revival as best I could, including giving away tens of nillions in total, and lots of long rambling articles on my views on ethics and philosophy and frankly it's worked better than I would've really expected (or at least it has coincided with an effective recovery of the community). The community also helped me through at least a couple hard times personally in there as well.
The technical situation in Nyancoin is mostly unchanged but slightly improved, although with two additional known vulnerabilities. It's unchanged in that it's the same client. It's improved in that we have an active nyanchain explorer host (nyan.space), and we have a public draft of a plan for a soft forking security fix update in the near future (hopefully by the end of March (although I've slipped these deadlines before and may well miss March for release by a bit, I do think I'm inching closer now and then)).
The most serious vulnerability is to forking. This is the bug which hit Peercoin if I recall correctly. NYAN2 is intended to solve this through its soft fork from the LTC fix upstream (from the BTC fix upstream). In the meantime, we've been lucky we haven't been attacked. The tiny marketcap probably helps with not being a particularly attractive attack target. We're not exactly about to pay ransom to move faucet outputs. But that's no excuse; we want this fixed and should have it finally done "soon" (tm).
The less serious vulnerability is to a time warp attack in the difficulty function (Kimoto Gravity Well), which relates to general weaknesses it has and issues we've had with large gaps in the block chain because of spikes in the difficulty function causing it to be unprofitable and driving away most of the hash, and then low difficulty and price rise making it attractive to more hash, creating a spike and causing it again. While this is irritating, the chain still works, even if there are fits and starts at times. An important part of the reason I can get away with this is because there is at least one Nekonaut-supporting miner, CartmanSPC, who rescues us from time to time, and did so during the course of this article being written. We have a bunch of pools, but sometimes the hash just isn't there to get us unstuck when the difficulty goes high enough. Another part of the reason I consider it not an especially serious issue is because there's a workaround which works for me (classic bad developer logic): I use a large transaction fee (generally 337 NYAN, although I might have halved it after the most recent halving, I'll probably use 337 again) on my personal wallet by default. If necessary, I use a couple of them. It can make NYAN profitable to mine again despite the higher difficulty and "unstick" the chain. The difficulty function can go back down again in the next block if the gap has been long enough, so that can be enough to keep it going again for a while (although it can also get stuck again irritatingly fast at times). A fix for this will be putting in a better difficulty function for NYAN3, which will require a hard fork. This is tentatively scheduled for feature freeze around the middle of this year, coding to follow, activation sometime early 2017.
Financial has been our most disappointing performance. A graph of the 1 year performance right now on coinmarketcap looks pretty sad, showing our fall from a little over 60 satoshi down to around 7 satoshi now.
We rose too high, too fast, and I didn't stick with the safe high paying job like a sane person. Instead I hit the road, went to jail, and worked minimum wage. That doesn't sound like a sentence from a cryptocurrency financial review, does it? But the performance of NYAN since the article has been the story of my personal finances, which is the story of my life since then.
So, autobiographical coinaday interlude, trying to keep it generally to the most salient points. Well, in 2014 I had been on my way home to Minnesota from California when I was pulled over leaving Eureka, Nevada for speeding (got sloppy and went 45 approaching the 45 sign and thus technically still in the 35; bored cop seeing out-of-state plates). My vehicle reeked of weed, what with having been in Mendocino County previously with no intention of traveling out of the county much less state anytime soon but family emergency brought me back, and the end result was a citation for possession of cannabis and paraphernalia along with the speeding.
Fast forward to the beginning of 2015, I'm settled into a good software position and start looking more at cryptocurrency in my spare time. I write the coin-a-day series for a bit and then got annoyed and quit after a while when trying to do one a day on top of an actual job was too much for me (along with some annoyance over criticism; I can be rather thin-skinned at times). But I had gotten interested in Nyancoin, and started buying it up more and more with extra money I was making.
And then comes the crash. I had to stop putting as much in as I realized that where I was living and what I was working on wasn't going to work out for me and I needed to figure something else out. So, as I seem wont to do, I went on a roadtrip. I quit my job. And I went back for the court date for my citations and refused to pay, instead spending 10 days in jail rather than pay ~$1400 (I actually had the money in cash available to me if I chose to pay as a backup if I chickened out, but the judge annoyed me enough that I really preferred to be jailed instead of paying, as stupid as that sounds since I'm quite sure the judge didn't care in the least one way or another).
After that, I went back to roadtrip lifestyle for a while. It was a nice period. A lot of beautiful scenery; a lot of reading. Eventually, I busted up my car pretty badly...a couple times actually, the second time for good. Fast forwarding through the rest of the year, I worked a couple minimum wage jobs to pay bills and avoid cubicle life and kill some time until I figured out what I was going to do next. Just recently I quit as delivery boy after getting a speeding ticket (I swear, I'm not as horrible of a driver as this makes me sounds, although I have had a bad tendency to speed in the past, which I really have curbed to almost nothing; but I'm clearly not good enough) and am currently writing a Coin-a-Year article with a friend's incentive and applying to do documentation and development with the Nu project.
Okay, so what did any of that have to do with NYAN? Well, it's the mess of a life that has led to the fall of the price from 60 satoshi to 7 satoshi. If instead my life history for the time since the article had been simply "I was happily employed writing software", then I don't believe we would have dropped below 20 satoshi. It's easy to see in hindsight. If anyone can lend me a time machine, I'm sure I can get some condensed instructions which should improve performance significantly. Otherwise, just going to have more chalked up for the "character building" tally.
So, lessons learned if you are the major buy support for your coin: you need long-term reserves. Whatever you put in bids can be taken out in a moment by a dump for no apparent reason. This is particularly true if you may be quitting your cushy, high-paying job and wandering around without income for an extended period of time. Rather obvious, but hey, maybe someone else can learn from my mistakes. If I'd been bidding as cautiously as I am now from the beginning, I think the price would probably be somewhere from 10-20 satoshi now instead of around 7 satoshi.
It's especially unfortunate given that I wanted to be able to demonstrate the more consistent growth possible building a stable store of value, as opposed to the pump and dumps common in altcoins. And instead we had a pump-and-dump looking graph ourselves after I bid up higher than I was able to sustain, and a large (10+ nillion) instadump crashed the market all the way back down to 1 satoshi momentarily. We've had a few large (2+ nillion) dumps since, but nothing that large. We haven't generally had that large of bids though either.
It's hard to know when I've exhausted the supply at a price level, when it sometimes waits for a couple weeks or even more and then fills all the bids at once. But I want to maximize the minimum price paid because I think that's important for building confidence in a store of value long-term, which is one of my core goals for NYAN.
At the same time, we're still up from the lowest parts of the floor and where I found it. Since I own about 30% [g], the very cheapest supply has been taken off the market. I plan to keep on buying up "cheap NYAN" as much as I can. I've bought up to 60 satoshi before, I'll probably buy up that high this time around. I've got a token 100,000 NYAN ask at 300 satoshi; I hope never to sell lower.
Conclusions
Now I try to wrap it all together as if I saw this all coming and am the wise expert, despite having had about 90% drop in price in the last year after bidding too high. My original concept was taking the "minimum viable coin" and reviving it to a powerhouse as a textbook example in how to do it.
Part of my core concept in this is the arbitrariness of value: throughout history, humans have chosen any number of things as a store of value for the time: salt, large rocks, certain metals, disks, marked sticks, and so forth. While there has generally been a certain logic in the choice, in that there is a locally restricted supply in one way or another, and so forth, from the perspective of other centuries or cultures the choices can seem quite strange. Growing up, I was always struck by how strange the notion of salt being limited and valuable seemed in a world where people were trying to reduce intake and large amounts could be bought for trivial sums. And yet, a key nutrient necessary for life fundamentally makes more sense as being valuable than notched sticks or printed paper or a piece of plastic with some encoded information.
Humans have perpetually come up with stranger and stranger ways of storing and transferring value. Each new step, as always, comes with its own disadvantages and, frankly, has generally appeared nonsensical at best and fraudulent at worst to the status quo. Which doesn't mean that each new attempt is valuable. The gold bugs always like to point out that every fiat currency ultimately returns to its true value of zero. And the skeptics of cryptocurrency argue that all cryptocurrencies will eventually return to their true value of zero.
It's certainly possible. And it's possible the USD will hyperinflate someday. I tend to try the moderate view for a plausible guess of the future. By that type of logic, I would guess that over the course of decades, USD will in general lose value, and cryptocurrency will tend to slowly gain value. That might not seem the moderate view, but USD not losing value over decades would be truly shocking. And hyperinflation has been predicted since the USD went off the gold standard, or before. So some amount of inflation less than hyperinflation seems like the safe guess (but then, the Titanic arriving would also have seemed like the safe guess to me). And with cryptocurrency, I think it's clear by now the technology will continue to survive. So my first question is with what overall value as a market? It could go down, of course, but that seems unlikely in an already small, young market. Even if all the current crop die off and are replaced, whatever cryptocurrencies are around should be able to do better than a handful of billion in market cap in my view.
I believe that cryptocurrency has a bright future ahead of it. The best coins should ultimately survive and thrive. But I've been wrong on most of my major calls so far, like for instance when I thought BTC was over-priced around $5-$10.
I think Nyancoin can have an important role to play in the future of cryptocurrency in the years and decades to come, but it's a massively speculative long-shot. See also Nyancoin risks document. But like Linus Torvalds' autobiography, I try to keep "Just for Fun" as a core motto and principle. It's makes for a good hobby project because there will always be more to work on, with a core community motto of
TO INFINITY AND BEYOND!

And I'll reiterate that I own about 30% [g] of the current supply of NYAN, which makes me by definition maximally biased.

This is the first sponsored article. This Coin-a-Year article has been brought to you by spydud22 's generous patronage. I'd been meaning to do a Coin-a-Week article on Nyancoin for a while, but between wanting to "wait until the price recovered a bit" and general procrastination, then it seemed like it would make a good Coin-a-Year article, and then I wanted to wait until the price recovered a bit more...anyhow, so thank you spydud22, for causing me to finally do this. :-)
Footnotes
  • [a] nyan.space/chain/Nyancoin ; as of block 1091430, 263738786.71890615 NYAN outstanding. This is slightly over 50% more than the last report, which is what we would expect, since it had existed for about a year then, and has approximately annual halvings. The first year generated about 50% of total supply; the second year generated about 25% of total supply. We should expect in a year to have about 17% (one-sixth) more than we have now.
  • [b] https://www.cryptopia.co.nz/Exchange?market=NYAN_BTC ; this is the only market reflected in coinmarketcap and it is the primary one on which I trade. Cryptopia also has other base pairs which operate at significantly higher spreads (lower bids; higher asks) and have minimal volume. In the time since the last report, NYAN has traded as high as 60 satoshi (and briefly a little higher at times), but over the last almost twelve months since a peak about a year ago, the price has been generally declining overall, as a gross oversimplification of a lot of movements. This has been an effect of me not being able to keep buying as much and there being large dumps I wasn't expecting from time-to-time. Now I'm taking the approach of building large (one or more nillion (million NYAN)) bids on each price as I slowly work my way back up again in order to be able to handle possible dumps with less price shock.
  • [c] coinmarketcap.com/currencies/nyancoin/ ; as noted in [b], this only reflects the /BTC basepair on Cryptopia but that's where most of the volume is anyhow. Of course, the market is also not particularly liquid since I'm the primary buyer and have rather limited means currently.
  • [d] I haven't setup a script to count this yet, among many things on my to-do list for someday, so I went through by hand from what was the then-latest block of 1091430 on nyan.space back to 1089766 which was the first block generated less than 24 hours before. There was actually a three and a half hour block gap at that point, such that the next prior block was about 24 hours and 15 minutes before 1091430 while 1089766 was only about 20 hours and 45 minutes prior, and has a disproportionate number of transactions and value compared to a typical block (8 and ~313,000 NYAN respectively) from the build-up during the gap. But since that gap conveniently started right about at the start of the 24 hour period, doesn't really skew our results here.
Note that there are often times where the UTXO created during one transaction during the day is spent during a later transaction in the day. This can be considered the "same" Nyancoin being "spent" twice in the same day in our total. But in practice, I believe what's happening here is the faucet is breaking off small (10-50 NYAN) pieces from a larger (~40,000 NYAN) chunk, and so that pops up a bunch of times. So the total NYAN blockchain volume as counted for this topline number should not be interpreted as "NYAN spent in the day" but "NYAN moved on the chain", where the "same coin" can move many times. So it's a very easily gamed metric and not a strong / resistant metric like the market price tends to be (at least relatively speaking), but it's a fun number to calculate and provides a little bit of information.
The transaction count can also be easily inflated and certainly, for instance, having the faucet does generate transactions which are a very common transaction.
And this is also just an arbitrary 24 hour period compared to a previous arbitrary 24 hour period. Nonetheless, I do think there's clearly a bit more activity on the Nyanchain, even though the typical block is still empty and the number of transactions and volume is still tiny compared to the major cryptocurrencies.
Here's an arbitrary example of the faucet transactions Note the zero transaction fee, which I love that the miners support (the defaults are all quite low as well).
Here's an example of what may be the smallest transaction by NYAN volume of the day; but no, I followed its small, spent output, and it led to this gem which also links to this. I have no idea what's going on here, but it's hilarious and I love it. How's that for microtransaction support? :-)
  • [e] Obviously Cryptsy went down. We had had more than enough red flags with Cryptsy (including one time where I was able to withdraw 6 nillion more than I had in my balance) and got onto Cryptopia. spydud22 basically accomplished that for us, although I helped out in the tail end of the campaigning.
  • [f] Our community is still small (I wish there were literally dozens of us!) but we've had valuable activity from multiple people, including, just as highlights, vmp32k who hosts nyan.space, a clone of the original nyancha.in, jwflame who created the excellent nyancoin.info intro site, with the awesome status page (which currently notes that "the last 500 blocks actually took 111 minutes, which is approaching the speed of light, causing the universe to become unstable"), KojoSlayer who runs the faucet and dice, spydud22 who got us on Cryptopia, and many other Nekonauts have made worthy contributions, and the Nekonauts mentioned have done more than just that listed. So while we are small, we are active at least from time to time and technically capable.
Even though our posting rate is still around 1 post a day or so on average, and so still a relatively quiet subreddit (and it is our main (only?) hub), it's still a very noticeable and significant difference from how /nyancoins looked when I was reviewing it for the original piece here. Here's an attempt to approximate what was there using Reddit search ; archive.org has a snapshot on January 19th, 2015, which is well into the early revival mania and one from August 14th, 2014, before four and a half months of little to no activity. Apparently archive.org unsubscribed to /nyancoins in that interval itself...
  • [g] Maybe up to around 35% by now; maybe still around 30%. I haven't updated hodling report lately; it was 30% last time I recall, but I've bought more and more has been made since.

Vertcoin's Recent Decisions. The damage hasn't been done yet, please join me in stopping the madness!

Foreword
Alright, I’ve been sitting on the sidelines about most of the dealings with Vertcoin because I felt like a lot of the sensible voices were loud enough on their own. Many people have stepped up to the plate and developed amazing products that benefit Vertcoin at no addition expense to the original development team. I’ve seen and helped test/brainstorm some incredible projects. Vert.geek.nz was a great example: a project that promoted p2pool mining while still allowing miners to reap the benefit of merged mining. Before nzsquirrell brought us this product we were all forced to either solo mine or to switch to a mining pool that support merged coins (namely SimpleVert at the time). V2p was another amazing product. There's the One Click Miner that's being developed right now... There are a lot more, but my point is that people were able to see a need for a new service, and build that service without any voting or public funding or whatever. And they did an amazing job because they thought things through. With input from multiple sources, and a slow, steady brainstorming session, they were able to develop something that really couldn’t have been made better.
Democracy in Action
Alternatively, Vertcoin itself is being left to an absolutely ridiculous voting process right now that WILL destroy the coin, and here’s why: The democratic process doesn’t work. If you build a system by which the majority can make these kinds of decisions, you create an environment based purely on mob mentality. If I can convince a large enough group of people that a certain idea is better than another, I win. This is extremely bad if you’re trying to gather interest from investors as well because it creates too much variance in coin value and feature sets (the idea of changing the also they would probably like, since that’s something Vertcoin has been about since the beginning, changing the inner workings of the coin simply to combat a single “problem” is VERY BAD if you want to attract investors because they see these moves as signs of weakness).
Development
Now, I’ll come back to the VertVote process later, because I think the most important thing to talk about right now is the decision-making process on the part of our developers.
The VTC dev team has done numerous things that don’t make sense to a number of users lately, and they need to be addressed. First, the website update. We’ve beat this horse to a pulp, and I understand that, but I think people still need to keep this in mind. When the new site was released, there wasn’t any input from the community. There wasn’t any play-testing or public brainstorming done to help promote discussion that might have found issues with this site. For example, the “Mining” page still doesn’t have a single mining pool listed, which leaves a user to go out and find a solid pool on their own. This isn’t easy, especially for someone who doesn’t even know how cryptocurrencies work (the primary audience for a site like this should be users with no crypto experience). The same goes for the “Details” page. There’s plenty of technical information, but that doesn’t mean anything to a regular person. They don’t know what an algorithm is, or what block times/rewards are… It even mentioned merged-mining, without any information on what that is. It’s just confusing for a newbie.
Management
Second, and similarly, the marketing fund got thrown into a pit of uselessness. Vertcoin.org was advertised to miners on a site where people go to see the profitability and mining calculations for a number of coins. Let’s just say that the ad actually catches a miners eye and they click on it. It would lead them to a site that has no information on which mining pools they can/should connect to, aside from p2pool. So the most common frequenter of that site can’t access the most important information he would want from the Vertcoin website. I want to know how that seemed like a good idea.
Alternatively, a group of dedicated Vertans (including one miner that has somewhere in the ballpark of 40 rigs, so he’s pretty damn dedicated), built an entire site from scratch that addressed a number of things for regular folks who we should be attracting to Vertcoin, and presented it to the community and the development team. I realize that there’s a sort of pride in work mentality that might have made the devs prefer their own site, but in this case the new presentation was, in my opinion, better. Furthermore, the devs could have taken this new site and moved it over straight away with almost no other changes, besides a couple small fixes and integration to include mobile browsers. Instead, all they got was a 'thanks for the suggestions, I’ll use some of your stuff if it seems fitting’. If you want to check out the alternative site that a few dedicated Vertans built, check it out here.
VertVote
Now, I promised to come back to VertVote. VertVote says on their front page: "You may vote once on any active poll. Make your voice heard Vertan!”, yet there’s literally nothing stopping a member from voting multiple times. So now we’re making decisions about the life of the coin based on how many possible mis-informed people vote for something, with the honest folks losing out more than anyone else (since the honest ones are the ones less likely to cheat)… Probably the most important factor for VertVote would be the fact that it's in the hands of such a knee-jerk crew right now. I didn't even realize that the vote for block maturation was actually a decision-making vote. I assumed it was simply a poll that the dev team wanted to conduct to get a gauge of how strongly the miners feel on the subject. Instead, they took one of the most poorly worded/conducted votes and turned it into the final decision on the continuation of the coin. That was the wrong decision.
Not only that, but it appears that the dev team has decided to interpret the voting results however they see fit, without letting anyone know the conditions of the vote in advance. The example of this being that fact that they completely disregarded the winning vote and instead gave the vote to the second-highest result. To me, this would be like throwing the clear presidential winner out because he only had 49% of the vote (so 51% didn’t want him) and instead picking the candidate who had 30% of the vote simply because he was among the majority… It makes no sense, and if you were going to start a vote with such a senseless base to it, you should have stated as much and given voters more time to decide before they cast their vote(s).
As for the VertVote manipulation, for those who don’t believe me. It’s incredibly easy, and ridiculous. To test things out, I used 100 VTC, spread it out across 10 VTC addresses and cast a vote from each. Nothing in the site, not even a browser cookie, stopped me from casting multiple votes. But then I thought a bit more. Why limit myself by how much VTC I have? All I need is 10 VTC in an address at the moment I cast my vote. So really, I just need 10 VTC plus [number of votes I want to cast] times [transaction fee to send 10 VTC]. I could just keep creating wallets, sending the 10 VTC to the new wallet, and vote again… On the other hand, one of the measures to fight against this behavior is a block on IP addresses submitting multiple votes. This doesn't seem all that logical, considering multiple people could reside at one location / share an internet connection and not be able to voice their opinion as well as a single person / internet user.
Economically, These are Bad Decisions
As for the block subsidy change proposal: This is getting out of hand. Cryptocurrencies’ values need to stay in line with regular products and fiat currency. A very successful cryptocurrency should have about a 1:1 ratio with things normal people are used to. What this means is that we want Vertcoin to settle in value somewhere between $0.50 and $3 each, so that normal people can easily convert the value and go from there. Artificially halting/slowing the production of Vertcoin may result in a slight pump in value, but ultimately it will detract investors because it causes more variance (who knows what the devs/community will want to do next) and it makes Vertcoin less easy to calculate compared to what they’re used to (i.e. the dollar, euro, etc).
Think of it, literally, as a coin. If Vertcoin were an actual coin and each coin were worth over $100, people won’t exactly want to carry it around. For this reason, Bitcoin community members have been discussing creating a denomination of sorts, so they could refer to smaller increments of BTC as something like bits and have each bit worth $0.10-1.00. Your proposal would do the exact opposite and make Vertcoin even more difficult for the layman to comprehend.
Minor side-point
One last thing, and this is mostly unrelated (I noticed it during my experimentation): Vertcoin-Qt has an option to view a transaction on VertExplorer, even though VertExplorer isn’t even around anymore. Alternatively, there’s explorer.vertcoin.org, which works fine. Can the devs please change the wallet so that it can reference transactions without having to copy, browse to explorer.vertcoin.org and then paste/search for that transaction?
For Those Who Think We Need VertVote:
I ask you this, what did you come here for? Did you like Vertcoin, or did you like the idea of a coin that could be constantly changed on the whim of a couple hundred votes? We all bought into Vertcoin because we liked what it stood for (ASIC-resistance), and the economics of it were sound. Even now, the economics of it are only frowned upon because we see so many PoS coins taking over the market. Nobody's out there suggesting we switch to a PoS model, even though PoS is patently anti-ASIC, ASIC-proof for that matter. The whole point of cryptocurrencies is that they are void of any centralized control. If we leave this coin up to the decisions of those who hold it, we're still centralizing the currency's control to those people in particular. Instead, we should be basing the currency on a constitutional model (by that I mean that there should be absolutes that won't be changed, such as the block reward schedule, total VTC supply, time to block solve, etc). The technical details should only change out of absolute necessity to maintain the requirements laid out in the coin's "constitution". In this case, changing the algorithm makes sense, because it maintains the constitutional requirement of being ASIC-resistant. Changing the block reward is just an idea that people like because they see it as a way to increase the value and ROI of their current holdings, without regard to the fact that it'll scare off practically any conscious investor.

Question regarding overall Hash Rates I'm seeing on p2pool

Okay, pardon me if I blatantly show my ignorance at some point during this post, but I was hoping to see if you guys could help provide some clarity. I know as it stands getting an ASIC miner that can mine at a TH/s rate is difficult because of back log, and people buying them up and then re-selling on ebay.
However, not including that tidbit, I've been looking at Dash p2pool node listings, and the one trend I'm noticing is that none of them are really even close to putting out TH/s hash speeds. So I'm wondering, is everyone just so glued to bitcoin that no one feels the need to use powerful ASIC miners to mine DASH, or are we just still seeing the delay from when people ordered their powerful TH/s ASIC miner's back in October, and November?
It just seems crazy that anyone who has a ASIC miner that can pump out anything over 1 TH/s and only use around 1800W, would be mining anything other than DASH. The mining calculators I've been toying with when factoring upfront hardware cost, my areas low electricity costs in comparison to what I'm seeing elsewhere, pool fees, and available computational power, are showing that the potential profits that could be generated from 16 TH/s ASIC miners are actually kinda crazy, even considering the high upfront hardware cost I'm seeing from pretty much every ASIC producer.
I'd like to state again though, if I'm just royally out to lunch here, and totally missing the mark, then please feel free to burst my bubble and lay down some education. I am just beyond fascinated with the development of these ASIC miners, especially these ones that are claiming to produce what seem to be pretty amazing levels of efficiency in terms of Watt usage.
Any clarity here would be super appreciated, and thank you in advance for anyone who takes the time to churn out a response!
Cheers

Toomim Bros supports democracy and Bitcoin XT with ~350 TH/s

We just sent this email to our customers:
The future of bitcoin is determined by the people who use it, and especially by the people who mine it. Each hash calculated on a block is a vote for how the bitcoin network should operate. Up until now, we've effectively had a one-party system. It's a distributed democratic system that has heretofore been left unused. That has changed. We the miners now have the power to determine the future of Bitcoin.
If you are currently using one of our p2pool nodes or are considering doing so in the future, you have a decision to make. If not, feel free to disregard this message. If you use p2pool but don't care much, you can disregard this email as well, and we'll make the decision for you.
As some of you are aware, a version of Bitcoin XT with code to allow for a hard fork to increase the maximum bitcoin block size was released less than a day ago. You can read a description of Bitcoin XT and some of its motivations, Mike Hearn's Manifesto for the release, and Gavin Andresen's exhaustive list and rebuttal of counterarguments for bigger block sizes for more information on this debate. For news supporting the use of Bitcoin XT, you can check out reddit.com/bitcoinxt and voat.co/v/bitcoin. For news that censors anything promoting the use of Bitcoin XT and moderated to favor the status quo, you can check out reddit.com/Bitcoin.
Mining with Bitcoin XT will have no major differences from mining with Bitcoin Core unless 75% of the last 1000 blocks mined are mined with XT or a derivative. If this threshold is ever reached, then a waiting period of two weeks will start, after which XT nodes will start to accept (and possibly create) blocks up to 8 MB in size. The creation of a > 1 MB block will create a hard fork. There is no way to increase the block limit without a hard fork, and demand for bitcoin transactions will soon exceed what can be supplied with 1 MB blocks. Some people think that creating a hard fork like this could kill Bitcoin. I think this will save it.
Toomim Bros operates two p2pool nodes. We have switched one of those nodes to use Bitcoin XT, and we will leave the other one on Bitcoin Core. That way, our customers can choose whichever node they want in order to make their own vote for how Bitcoin should be run. Everyone is welcome to use these nodes, though you won't have great mining efficiency unless you're inside our datacenter.
So far, Bitcoin Core (and consequently all Bitcoin protocol) development has progressed on a consensus model. All of the main developers have to agree to a change in order for it to take effect. For any important change, there will always be some people who are unhappy about it, so consensus only works for making important changes in oligarchies, and even in oligarchies, it doesn't work well. We at Toomim Bros think that decisions about how Bitcoin should operate ought to be democratized. As such, we support the existence of Bitcoin XT and think that all miners should have the option to choose which version they wish to support and use.
Toomim Bros also thinks that 1 MB is way too small, and that the network can and should support larger blocks. We think that one goal for Bitcoin should be minimizing the real cost per transaction. Currently, that cost is supported primarily by the block subsidy, and runs at about 65 kWh per transaction. (300 MW mining network, 1.27 transactions per second.) That's about $4 per transaction. Increasing the transaction volume would not directly require any significant increase in the mining network power consumption, so it would reduce the real cost per transaction. Our facility spends about 80x as much on electricity as it does on internet connectivity. We do not think large blocks will present a large burden on small bitcoin miners like us.
As such, we are putting the miners owned by Toomim Bros (the company) and the Toomim brothers (the individuals) on the XT node.
We're running XT on 74.82.233.205:9334 (global IP) or 10.0.1.2:9332 (LAN IP), and Core on 74.82.233.205:9332 (global IP) or 10.0.0.1:9332 (LAN IP).
(We also will probably be changing our IP address for these nodes soon. I'll publish details about the new IP once we're ready to make those changes.)

We are a medium-sized (750 kW, soon to be 2.25 MW) bitcoin miner hosting company located in central Washington. Visit http://toom.im for more information on us.
I'm interested to see how our customers vote. Most of our customers don't use p2pool right now. It would make me happy if some of them decided to switch to p2pool in order to be able to vote for XT.

JavaScript mining client

Hello miners,
I'm looking for a JavaScript CPU based mining client for really any cryptocoin out there. I'd prefer bitcoin of course, but I'd be down for some of the others if you got a scrypt one.
I'd really like it if this JavaScript miner is able to work on a p2pool node, but not required.
do they all require backed server commands or can it be purely the JavaScript client doing all the work?
This is purely for an ethical project. (not gonna go XSS a bunch of people)
edit: I know it would be slow. the thing is JavaScript can be distributed through web applications, and also used for human verification. if it could calculate one hash in less than 10 second that one be enough.
edit 2: So everyone says you cant, but then I find this: https://github.com/derjanb/hamiyoca
even supports gpu

Here is my statement on nowadays pool mining. Do what you want with it.

Hello everyone,
I don't care about what you'll do with this post, either downvote it to hell it won't matter. I'm the pool operator of one of the regular litecoin pools crunching blocks at a regular rate. I won't say the pool name, it's not about ad and getting more miners. It is about nowadays litecoin mining and how the future is likely going to happen (from my pool operator point of view)
From my very own point of view, everyone should avoid profit switching pool as it is "short termist" and hurts the coins you'd put your trust into.
That is to say : the serious centralized mining pools you're seeing (and likely using) now are likely to be the only ones you'll see during the next years. Some of those pools will close, be hacked, AND THIS LIST IS LIKELY TO SHORTEN DURING THE NEXT YEARS
I'm not saying this is a problem or if this is good or bad. I'm just saying that it happened, just as it happened to bitcoin before : The Litecoin Network Difficulty is now too high to diversify the mining pools, miners elected the "rock solid list" of the mining pools we'll be using now and further for the next decades.
Now here is my question : if the miners aren't interested in P2Pool mining (for whatever reason, this is just what we see from the reported pools hashrates), how will it be possible to fight against 51% if it is harder over time to start a pool, leaving a short list of "historical" pools that are likely to close over the next decades, or be hacked ? What about the guys who haven't yet started a pool, but would have had the guts to become the next eleuthria of litecoin pools ?
Redditors, what do you think ?
