How to answer the 'Pre-Mining Question'

A full disclaimer: I am not a member of the Quark dev team, nor am I officially related to quark in any capacity. I'm only very modestly invested in quark, no more than other cryptos and far, far less than Litecoin. Still, I believe in cryptopluralism, so I want to answer this nagging question of quark pre-mining.
Much has been made in /bitcoin and other subreddits about the fact that 98% of Quarks that will exist have been mined and that mining will continue at a set rate of ~1 million Quark per annum (~0.5% rate of inflation). I want to address this issue to pointing out what it brings to the table.
There are two big problems facing Bitcoin right now. First, ASIC-led mining cartels who are de facto centralizing the day-to-day operation of the bitcoin network. There are a number of academic papers that indicate severe structural flaws that existentially threaten the bitcoin network if the extent hashing pools collude in certain ways. Second, Bitcoin is a terrific store-of-value, but so far it's been an abysmal currency. BTC faces several barriers to widespread circulation as a currency; among them are the yield on holding (as proponents target 1k, 10k, 100k) and issues of divisibility (right now we're seeing a hap-dash adoption of the mBTC standard).
Because of the 'buy or hold' paradox (which have a number of unwieldy solutions for merchants to avoid fluctuation risk), cryptocurrencies need an everyday spending coin and this is the niche that quark can fill. The 257m current circulation assures the commonness of quark, which in turn guarantees that quark can be exchanged/transacted without fear of future fluctuation. I personally don't believe that quark is severely undervalued; I feel as if a proper valuation would find itself squarely, stable-y within the $1-$5 range and stay there.
Further, the 257m figure and the lack of future inflation (in any meaningful sense) means that Quark, once it finds its parity, won't be subject to the same sort of speculating and day-trading that are a mark of scarcer coins; you're not going to have a future glut of coins that drive the trading dynamo as speculators buy the coins that miners sell.
The 1m per year inflation is a token prize that helps to maintain the hasing-network and transaction confirmation while making up for coin-loss. It's also directly positioned against allowing for the type of mining centralization that we see in Bitcoin, because the rewards are far fewer.
A couple of other points:
I have to say that Quark confirmation times are much, much faster than any other coin I've used. I'm actually surprised at how fast confirmation times are. When I traded for my first quarks, off of an exchange, I had six confirmations within two minutes and 92 by the ten minute mark. A crypto of speed is required for small-order brick-and-morter transactions. BTC is terrific for large purchases (say, a car) when it would be expected to sit around while the network confirmed the transaction, or for online commerce in which time doesn't matter all that much. But to be a POS solution in physical shops, a coin need to be fast.
I also believe in crypto-pluralism. Nature abhors a vacuum and the market abhors a monopoly. I firmly believe that we'll see concurrent, competing virtual currencies when this technology meets mainstream adoption. In this current stage of market speculation, frictionless capital transfer between cryptos means that they can absorb each other's market fluctuations. For mainstream adoption, it's necessary to have multiple prominent cryptos that all employ different hashing algorithms; this is, perhaps, the unintended heart of Max Keiser's "BTC/LTC/Quark" comment. Bitcoin uses SHA-256, Litecoin uses Scrypt, and Quark is 6-factor. The difference goes beyond the fact that most cryptos are literally copies of SHA-256 or Scrypt coins and has everything to do with risk. The prominence of cryptos will bring with it sophisticated attempts at attack; imagine the market panic if it is ever found that one of the hasing algorithms has a severe flaw. A monopole economy would collapse, a dipole would see such a marked capital flow and restructuration as to severely damage confidence. Three or more differently-hashed cryptos distribute risk in an acceptable way.

Argentina Sets New Trading Record After Central Bank Bans Bitcoin BuysBitcoin (BTC) trading set new records in two of its most keenly watched South American markets last week, new data has revealed.As monitoring resource Coin Dance confirmed on Nov. 10, the seven days ending Saturday (Nov 9) saw more trading against BTC than ever before in both Venezuela and Argentina.In total, Venezuela traded 142.9 billion sovereign bolivars (VES) last week, while Argentina managed 19.4 million pesos (ARS). Both are firm records over previous levels.
Bitcoin Called “First Successful Application Of Blockchain” By State-Run Chinese NewspaperChinese state news agency Xinhua has published a front-page article entitled “Bitcoin: The First Successful Application of Blockchain Technology,” according to Sino Global Capital CEO Matthew Graham.The lengthy article explains the main peculiarities of Bitcoin, an open-source P2P cryptocurrency, describing how BTC transactions and mining work. It also mentions that the price of the top cryptocurrency tends to fluctuate a lot, and it’s difficult to ensure its stability.
Canada’s First Legally-Delivered USD Stablecoin Launched By Blockchain Venture CapitalThe Blockchain Venture Capital Inc. (BVCI) has launched CUSD — the first legally delivered USD-stablecoin in Canada.The cryptocurrency is supplemented by a mobile wallet called Bvc Pay which is used to store, exchange, and trade CUSD over-the-counter (OTC).The same company also developed the world’s first stablecoin pegged to the value of the Canadian dollar (CAD) — first launched on Canada Day back on July 1, 2019.
Bitcoin Mining Difficulty Sees Biggest 2019 Drop As Hash Rate SpikesBitcoin (BTC) mining difficulty adjusted downwards more than at any time since its 2018 price low on Nov. 8, data shows.As noted by entrepreneur and cryptocurrency commentator Alistair Milne on Monday (Nov 11), difficulty fell by around 7% after the network’s latest readjustment.

After a major decline, bitcoin found support near the $8,670 level against the US Dollar. A new monthly low was formed near $8,674 before the price started an upside correction.
The price recovered above the $8,800 and $8,900 levels. Moreover, there was a break above the $9,000 resistance area and the 100 hourly simple moving average. The bulls were able to gain strength, but they faced a strong selling interest near the $9,150 and $9,160 levels.
A high was formed near $9,146 and the price is currently retreating from the high. It broke the $9,000 support area and the 100 hourly SMA. Additionally, there was a break below the 23.6% Fib retracement level of the recent wave from the $8,674 low to $9,146 high.

QuarkChain (QKC): Why I'd Rather Burn my Money than Contribute to this ICO

Taken from: https://satoshi.blog/2018/05/24/quarkchain-qkc-burn-money/
At least in this case i’ll be responsible for my loss of money. For me this is not a worthy ICO but that doesn’t mean it’s the same for you. Do your own research as usual. If you haven’t heard about QuarkChain (QKC) by now(I doubt it!), it is yet another blockchain promising a very high throughput. The key difference of their blockchain compared to the already existing ones? QuarkChain adopts the divide-and-conquer idea to separate the two main functions in two layers with the goal of a better scalability while guaranteeing security.
The network thus has two layers of blockchains:
This layer contains an elastic number of blockchains (shards). Each shard processes a portion of all transactions independently. This process increases the system capacity. The Casper Protocol being built for Ethereum to scale the network will be using sharding.
The rootchain’s responsibility is to confirm all blocks from sharded blockchains.
📷
Their blockchain would supposedly be able to support cross-chain transactions since the transaction from another blockchain could be implemented by converting the tokens by an adapter. The QuarkChain Network should also be able to support smart contracts via Ethereum virtual Machine.
This is the big picture of the project, i’ll let you go through the white paper if you want more information. I’ll concentrate my efforts on the multiple red flags i’ve encountered while trying to make sense of the project.

The Red Flags

Distribution

You can see the token distribution below. First, 2B QKC are available for investors. Participants of the private sale get 75% of it with a 25% bonus while ICO participants get 25%. Classy. There is a slow release of tokens but only 7 months after the sale, private sale participants will have been able to dump all of their tokens. The mainnet is set to be released in Q4 2018(it will probably be later than that since most projects have difficulties respecting schedules) So private sale participants will probably have been able to sell their entire stack before the product is even released to the public. Makes perfect sense, right?
📷
📷
Then the other 80% of the total supply is, as we can see on the picture above, divided between the team, the foundation, the advisors, mining(Oh we need tokens to mine now?), community and marketing. I don’t know about you but I think it’s pretty vague and when I invest in a project I like to know where the money will go.
As mentioned before, the community will get some of the tokens. To be able to get in the ICO, it is kind of a lottery system where participants get a rating based on:
The last part is a bit ridiculous because it creates an incentive for potential investors to portray the project only in a good light in order to maybe be able to get a piece of the pie.
Also, I think it’s important to mention that Ian Balina participated in the private sale. I’ll just leave it at that. He’s in it for the technology, right?

Potential attacks on the network

In the whitepaper it is mentioned that the root chain has a significantly large portion(over 50%) of hash power over the whole network. A malicious miner only needs 25%(50% * 50%) of the hash power to perform an attack on the network. What if the hash power on the root chain is even lower? It seems like attacking this network would be way too easy. We have seen recent events of 51% attacks on Bitcoin Goldand Verge. The number of different blockchains is going up at an alarming rate so the total available hash rate is spread around, making this kind of event even more likely for new projects. Blockchains just can’t tolerate the fact that someone with 25% of the hash rate can perform a malicious attack on the network.

GitHub and transactions per second (TPS)

They have a GitHub profile but it is private. Why would they do R&D, say that they have a good prototype but not show anything about it? In the whitepaper, they say the network will be able to do 100 000 TPS. Okay, and then on their website it is mentioned that for their latest testnet trial run they obtained a number of 2279 TPS. Where’s the logic behind this? Investors have no way to know what they’re investing in since the whitepaper is vague and the technology behind the project is not well explained.

Incentives

The token will be used as fuel for the network, like most blockchain platforms do.
Even after reading the whitepaper, incentives to hold the tokens are not clear. Apparently, and I quote
The essence of the virtual currency is the value carrier, which is the most important attribute of QKC.
How can the main value of a brand new cryptocurrency be attributed to its ability to carry value?
In my previous article How to Analyze ICOs I mentioned I don’t analyze a project in its entirety if there are too many red flags.
I’m out.

The Strange Birth & History of Monero, Part II: BitMonero

--YOU CAN READ THIS IN SPANISH HERE--
When i first knew about Monero i was hungry of information, and when i found the americanpegasus post about "The Strange Birth & History of Monero" i loved it. I looked for a second part for a while but as there was no trace of it i did my own investigations. Now i've decided it could be a good idea to paste the results here with the same format as americanpegasus did, to help new users looking for info about the "strange birth" of Monero.
Bitmonero - a new coin based on CryptoNote technology
https://bitcointalk.org/index.php?topic=563821.0
Notable comments in this thread:
-1: " Important: this is not a Bytecoin relaunch or not a Bytecoin replacement but a Bytecoin fork. Bytecoin has its own long history, community and stakeholders we don't know much about. I respect them and their decisions even if I don't understand them now. An intention to relaunch coin is always harmfull for everybody involved. Fork is a right way to contribute to community in case you don't agree with decisions already made. - Why did I make fork? - Because there is a number of technical and marketing issues I wanted to do differently. And also because I like ideas and technology and I want it to succeed. I did an announcement ASAP while a lot of details aren't still defined because the earlier it is announced the more people will be able to join. Details will appear as soon as they will be defined and decided.
Here are details that are already defined and I don't plan to change this:
  1. New coin will use Bytecoin(BCN)/CryptoNote code base.
  2. New coin is started from scratch (i.e. from genesis block).
  3. Emission schedule has a flatter curve (close to Bitcoin's original curve).
  4. Bitmonero - BMR (monero /esperanto/ = coin)
  5. Block target = 60 seconds"

-11: “I honestly don't see the advantage of bringing the block time down to 1 minute. You're ultimately looking at increasing orphan blocks and decreasing hash power, and all you get is a feature that looks great on paper but has little purpose. I wouldn't mess with it. Apparently the BCN devs wanted 5-10 minute block times but settled on 2 minutes after lengthy disputes. Their decision is explained in more detail here: https://forum.cryptonote.org/viewtopic.php?f=5&t=20”

-15: ” Block target isn't only about transaction speed.
It also influences the chance to get block in solomining […] Solo mining gives decentralization.
[…]
From another point of view faster block are smaller (less transactions per block). Small blocks are easier to propagate through network.”

(https://bitcointalk.org/index.php?topic=563821.msg6161218#msg6161218) [smooth supports Johnny Mnemonic proposal of bigger blog target]
-25: “There are very good reasons for having a fork instead. With BCN we have a coin that refused to show itself for 2 years and has been 80% mined. Why would the markets accept that? Crypto distribution is absurdly bad […] But this [BCN] is taking it to a whole new level. […]Don't underestimate "instamining" stigma - it annihilated Quark and continues to plague DRK
[…]
A fresh start pre-announced start gives a known market history, a fairer and longer distribution, and active development with feedback.
That said, I'm disappointed in what this thread turned out to be. We should've had discussion on the name and the parameters and other things and yet thankful_for_today is nowhere to be seen 4 days from the supposed launch.”

This coin had no discussion behind it. It was pointed that the block time is too fast beyond the solo mining phase. It was kept without offering reasons. It was pointed out that the name should be voted on. Nope, and a bizarre name resulted.
Perhaps the biggest reason to fork is that it was mined for 2 years without making itself available to the other 99.9999999% of the internet on the clearweb. Yet, we wouldn't be much better if we did a launch without a GUI client and a website. Instead, we were 1 hour from launch without a Windows client, which is actually a step backwards from BCN itself (they released an easy-to-use package with a batch file for nontechnical users). We need (1) an accessible release with (2) proper marketing (including a different name). Right now this fork doesn't have much of a reason to exist, IMO. There's no reason to release it now and work on these things later, either. All we'd be doing is unfairly mining it ahead of everyone else”

This would have been a huge problem for Bitcoin, as there was a well known bug involving integer overflow that allowed you to generate 2 billion coins.
Note that zero knowledge proofs are used in the ring signature method by ByteCoin/BitMonero, too (see section 4.4 of the whitepaper). Obfuscation of signature linkability is much more advanced than that used in DarkCoin, and you need to read the whitepaper to truly appreciate it.
CryptoNote also has support for multisig built in, despite the much more limited scripting language as compared to Bitcoin (see Section 6.3 of the CryptoNote 2.0 whitepaper). This is important for the implementation of decentralized marketplaces like DarkMarket that use multisig to enable the blockchain to be an escrow.”

This is basically everything worth reading in this thread. I’ve extracted the most important posts in the whole thread, from first to last page. TFT, Bitmonero and its community are key in the birth of Monero.
These are the main conclussions:
  • BitMonero has a reason to exist. But to justify its existence it doesn’t need just reasons, but also a dedicated team and a participative community.
  • Thankful_for_today definitely it is not a sociable leader. His posts are scarce, every few days, and he can’t keep up to date with a nascent community really dedicated
  • TFT is desperate to launch BitMonero, probably to be the first Bytecoin fork and have the “first mover” advantage. He is even about to launch without Windows client.
  • Due to the rush, TFT has induced a few bugs. The most important one the emission curve.
  • Bytecoin starts to have some traction, and TFT keeps ignoring community suggestions, so the community has now doubts of BMR future. NoodleDoodle, eizh, David Latapie, Tacotime and smooth among others lead a split, firstly just to change the name and re-publishing the announcement thread, but they will eventually hard-split.
I have already ready a summary of the MRO topic that has a short life of not even 2 days but still has A LOT of interesting info about how the team is being built and what are their opinions on several topics. May i remember you that by then Monero had 1 minute blocks and an emission curve that would have created 86% of the tokens in 2 years. In the next post (will only make it public if i see there's any interest) we will see how and when the team adressed the problems with the emission curve, and when was the miner optimized to take away the probably voluntary obfuscations the code had.

[Guide] No hardware to mine? How to net 6,000+Ð/day using Windows Azure

Inspired by lleti 's free guide for using Amazon Web Services. However, from what I understand due to rental costs, it is more efficient to buy doge directly than use AWS. This guide is based on utilizing the $200 credit that comes with the Windows Azure cloud computing free trial, so you will not pay anything.
This is targeted at shibes with poor hardware that can only mine 50-200 doge per day, but it will work for everyone.
Disclaimer: Doge rate is an estimate based on current difficulties and market. Windows Azure trial may be US only (?)
Overview / How it works
You will not be mining doge directly with this method. Mining doge effeciently requires a GPU, which aren't found in traditional servers. Instead, we will be using the powerful CPUs provided with Windows Azure servers to mine a CPU based crypto-currency, such as QuarkCoin or SecureCoin, and convert those to doge.
Steps
1) Install your QRK or SRC wallet
Ideally if you are reading this, you have installed a dogecoin-qt wallet for yourself before. We will need to do the same for either QuarkCoin or SecureCoin. This is the wallet where will will send the coins you mine with your Windows Azure servers.
These are not the only CPU coin options, but QRK and SRC are very similar (same hash function) and simple to mine.
Once you have installed the wallet, it should look very similar to your DogeCoin wallet. If you have trouble downloading the blockchain ('out of sync'), look at these threads respectively to see which nodes you need to add to your config file. Config files are located at C:\Users\UserName\AppData\Roaming\CoinName.conf on Windows.
2) Set up a mining pool account
If you have joined a mining pool for DogeCoin, it will be a very similar experience for other alt coins. See the following bitcointalk threads which have a list of mining pools:
If you would like a pool recommendation, I can recommend src.coinmine.pl and qrk.coinmine.pl; this is from personal experience, I am not affiliated with them.
Once you are logged in you should also create 3 workers, as we will be setting up 3 servers, one for each server. So you should have 3 worker names, and a password set up for each worker.
3) Sign up for Windows Azure free trial
Link: www.windowsazure.com/en-us/pricing/free-trial/
You will have to provide a valid credit card and verify your account with a cell phone so they know you are a real person. This is a Microsoft product so they are reputable. Once you sign up, you will receive a $200 to use in 30 days. Remember to cancel when your credits are running out so they don't charge you.
4) Create Windows Server instances
I would recommend you watch this video which walks you through the UI of the Windows Azure management site to set up the virtual machines we need. Essentially we are going to do the following:
Thus we have a total of 20 CPU cores to mine QRK / SRC with. We want the the most CPU power we can get without excessively burning our $200 credit. That's why 2008 R2 is used, and only 3 instances of it.
5) Remotely connect to servers and download miner
This section is also covered in the video from section 4, watch it for a visual walkthrough.
Once the servers have been initialized on Microsoft's end, we should be able to access them under 'Virtual Machines' at www.manage.windowsazure.com. You should see each host name and a status, and when selected there should be an additional 'Connect' button - click it.
You should now be prompted to download a .rdp file. Download this for each of your 3 virtual machines to a folder you will remember. You will open this .rdp file and use the login credentials you previously specified to connect to each server.
Once you are remotely connected, you should see the desktop. Open up the first icon on the taskbar that looks like a server, this is your server manager. We need to open up the 'Configure IE ESC' setting that's visible on this pane. Make sure 'Off' is selected for both admins and users on the IE ESC configuration.
Now, open up the IE browser and navigate to https://docs.google.com/file/d/0B9cvOfoOekSdVzZZcThLZHg4bjA/edit. Press Ctrl + S to download the entire zip to the desktop, and un-zip it.
6) Configure and start miner
Again, this is pretty much covered in the video from section 4, if you prefer watching.
You should now have a folder on your server's desktop named quark-v2_w64. This is the miner for both QRK and SRC. We are going to be using minerd64_sse4.exe. Create a shortcut to minerd64_sse4.exe within the same folder. We now need to add the parameters for your miner.
Right click on your minerd64_sse4.exe shortcut -> Properties. Look at the target field, it should look like this:
C:\Users\UserName\Desktop\quark-v2_w64\minerd64_sse4.exe
We are going append the following format to this target field
-a quark -t 8 -o stratum+tcp://src.coinmine.pl:6020 -u user.worker -p password
-a: algorithm, both SRC and QRK use 'quark'
-t: number of cores (so either 8 or 4 for our purposes)
-o: mining pool information (url and port).
-u: account you have for your mining pool, then a period, then a worker name
-p: password that you created for the worker in step 2
So here is an example of what the target field of your shortcut should look like when you are done:
C:\Users\Nexic\Desktop\quark-v2_w64\minerd64_sse4.exe -a quark -t 8 -o stratum+tcp://src.coinmine.pl:6020 -u Nexic.worker1 -p pass1
7) Profit!!
If you set up your miners correctly on each Windows Server VM (I prefer to assign a separate worker to each one), you should be able to run them and see an output like this: http://i.imgur.com/3lECqSz.png. You can close your remote sessions without interrupting it.
How do you get the doge, you ask? Well, using the above setup I have earned 10 SecureCoins in the past 2 days. These are worth 0.00094 bitcoins (BTC) on Cryptsy at present. A doge is worth 0.0000007 BTC at present, so if I go from SRC -> BTC -> DOGE, I can turn 5 SRC to 6,642 DOGE on Cryptsy. There are also other exchanges, I won't go into how to exchange coins on this post. Remember, this is every day for about a week, for free!
Also, you can CPU mine on your own personal computers as well, not just the servers.
TL;DR
Mine QuarkCoin / SecureCoin using Windows Azure free trial, use Cryptsy (or other exchange) to convert to DOGE. Much more efficient than CPU mining Doge.

How to Get The Most Profitable Cryptocurrencies to Mine and More in Google Sheets

Original Medium post found here: https://medium.com/spreadstreet/how-to-get-the-most-profitable-cryptocurrencies-to-mine-and-more-in-google-sheets-7b2ad2ebbdcd
One of the most challenging aspects of cryptocurrency mining is finding the most profitable coins to mine.
A few services exist, but nothing beats what the creators of WhatToMine.com have done in a few short months.
The big benefit of the data offered by WhatToMine is a ranking of cryptocurrencies by mining profitability.
The =SS() function, available in Google Sheets as part of the Spreadstreet Google Sheets Add-in, allows the user to pull in two seperate endpoints from the WhatToMine API:
  1. Stats — Used to compare the profitability of all GPU based cryptocurrencies
  2. ASIC — Used to compare the profitability of all ASIC coins

How to install

1. Go to the “Add-ons” menu, and click on “Get add-ons”.

Get Add-ons Menu

2. On the Add-ons panel, search for “Spreadstreet”, click on “+ FREE” to install it.

Click on +Free to install

3. Choose under which account you want to install the Add-on.

Choose Gmail Account

4. Spreadstreet needs to connect to an external API, click on “Allow”.

Click "Allow" when prompted
Note on security: All add-ins within the store go through a review. This is a wonderful security measure, especially in the Crypto industry, which is rife with scams and hacks.

5. Make sure the add-on is activated in your sheet:

  1. Go to Add-on > Spreadstreet > Help
  2. Click on View in store , then click on Manage and check Use in this document:
Click "Use in this document"
Tadaa You are now able to use the =SS() function to pull in all sorts of amazing data within the cryptocurrency space.
Example =SS() usage

How to use for GPU-Mineable Coins

How does WhatToMine calculate profitability for GPU-mineable cryptocurrencies?
What is the calculation missing?
Get most profitable GPU coins
Call the function =SS(“get-stats-whattomine”, true) to return various stats from GPU-minable cryptocurrencies.
Example usage using the GUI:
Open the Add-in

Click “Add” to view the list of available APIs

Click on the “WhatToMine” icon

Click “Stats”

Click “Insert”

Click “Run”. This will paste values into the currently selected Cell, and save that in the main GUI for future retrieval

Example usage using the =SS() Formula:

=QUERY(A:W,”select A, T where T is not null order by T desc”) returns the most profitable GPU-minable cryptocurrencies.

How to use for ASIC-Mineable Coins

How does WhatToMine calculate profitability for ASIC-mineable cryptocurrencies?
What is the calculation missing?
Get most profitable ASIC coins
Call the function =SS(“get-asic-whattomine”, true) to return various stats from ASIC-minable cryptocurrencies.
Example usage:

=QUERY(A:W,”select A, T where T is not null order by T desc”) returns the most profitable GPU-minable cryptocurrencies.

Common issues and how to fix:

  1. Do not keep your sheet open at all time. This will prevent the rates from refreshing. The rates will auto-refresh each time you re-open your sheet.
  2. The add-on may not work right away on other old spreadsheets. You need to do this to activate Spreadstreet: Open the old sheet, click the menu Add-ons / Spreadstreet / Help / View in store, and then click Manage and in the dropdown menu click Use in this document .

A few thoughts - Saturday, June 7, 2014

Today's thoughts are all about altcoins.

Litecoins are not dead

Several people have started to agree with me recently that litecoins aren't dead yet. But I wasn't quite able to give a concrete answer as to why, until a comment reminded me that litecoins are the most widely traded of all the altcoins. BTC-e, for example, doesn't deal in phoenixcoins and ronpaulcoins. Being widely traded is a significant advantage, even if the coin doesn't itself have any advantages.
I'm not sure why ASICs are relevant to the price of altcoins. ASICs are going to be distributed amongst miners just like they were with bitcoins; this just makes the miners fight a losing battle with each other, costing each other money. As long as one person doesn't get all the ASICs, it doesn't have any effect on network security.
A while back, all the speculation was that litecoins would overtake bitcoins once Mt Gox accepted them for trading. In the interim, however, we have several major exchanges trading them. When an exchange wants to expand into altcoins, they don't look towards the trendiest new thing; the first mainstay they adopt is litecoins.
The other advantage litecoins have is that there is a certain amount of "lock-in" with other coins. I've already commented about the concept of technological "lock-in." In this case, you have exchanges like Cryptsy that denominate some altcoins solely in litecoins. I found out that there is a class of altcoins that can only be traded Bitcoins -> Litecoins -> Altcoin. Even if you don't want litecoins, you still have to buy them if you want to play the game with these "penny stock" coins. That keeps their price high because even if merchants do not accept them, they still have utility and "acceptance" by exchanges.
Also, a quick thought to ponder: a lot of the reason why people buy bitcoins is that bubbles crash, things change, and bitcoins are still around. Have litecoins reached the point where people expect them to die, they don't, and therefore they think there must be something to them?

Max Keiser recommends Darkcoins; I do not

Max Keiser put out a tweet trying to sell darkcoins to his followers, saying he thinks they will recover after their recent bug-fueled crash. Remember that Keiser was also the one who said to buy the essentially 98% premined Quarks too, and that failure alone might be reason enough to ignore whatever he says.
I like the idea that when an altcoin has a lot of hype, it's not time to buy it. Darkcoins may have some benefits, but there is so much hype around them that there is almost certainly a bubble there. Don't confuse that with the idea that darkcoins won't have a niche in the future. However, just like bitcoins, there are times when hype gets out of proportion to the advantages the technology has.

Today's altcoin mining report

Altcoin mining profitability is all over the map today. If I had started testing this pool back during the last cycle, it would have been interesting to see if we could deduce any patterns from this data. As you can see in the charts at:
http://shoemakervillage.org/temp/altcoins2014-06-07.jpg
there are about 20 coins that are constantly switching as the most profitable. This may be partially a result of those new coins that have extremely fast difficulty adjustments. The chart isn't as useful without being able to mouse over the bars, but it gets the general point across just seeing all the colors. People obviously do not value most altcoins for their specific features anymore; most of them are just a game. There is one trend that is not all over the place:
http://shoemakervillage.org/temp/altcoins2014-06-07-2.jpg
The expected payout of scrypt coins is at $1.33/Mh/day now, which is completely opposite the trend of increasing bitcoin prices.

The effects of orphanage

Some altcoins reduce the block confirmation time by making the coin ridiculously easy to mine. There's no advantage to creating an altcoin that has huge numbers of blocks, because then all that happens is that your "confirmed' transaction is more likely to get orphaned. In testing, I was getting 30% orphanage rates on some of these fast coins. Look at what happened last night in the course of a few blocks:
http://shoemakervillage.org/temp/altcoins2014-06-07-3.jpg
However, I'm still trying to figure out whether orphanage actually reduces the pool's revenue or not. The conclusion I'm coming to is that it only cuts miners' revenue from the expected value if your orphan rate is higher than the average orphan rate of the network. If everyone has 30% of blocks rejected, then the blocks are still being created at the same rate and everyone gets the same amount of money. You only lose money if you have more orphans than everyone else does.
Am I missing something here? If not, then orphanage is only an indicator of a bug or of monetary losses if I have orphaned blocks for long networks like bitcoin, where having another pool finding a block within a second or two is very unlikely.

None of the altcoins has the innovation that bitcoin needs

The only true innovation from any altcoin that would pose a threat to bitcoin is if someone came up with a yet-unknown solution to the 1MB transaction limit, that will be permanent for an indefinite period of time, and released a new coin with it.
Some people mistakenly say that people will switch to altcoins to get around the block size limit, but that isn't the case because the most any altcoin has done to resolve it is to make blocks more frequent, which only raises the limit to some hardcoded value. Raising the limit to some hardcoded value isn't "solving" the problem, it's just putting it off into the future. Don't make a mistake and buy altcoins thinking that some altcoin is going to address that limit, because none has.

Altcoin code is a mess

Altcoins are a mess, when you are trying to compile their code. If you haven't done this with many coin daemons, which most probably haven't, then you probably don't know that almost all altcoins are just clones of bitcoin with some minor changes. This is one of the reasons why bitcoins have such an advantage, because you can't be innovative when you just copy stuff from the bitcoin developers.
What some people don't know is that most altcoins aren't even doing that. There are a few altcoins that have changed little in many years, so instead of incorporating fixes that have been included in bitcoin since then, those coins never upgraded to newer block templates and they don't include the latest features. It also means that bugs that were later fixed are still present in those coins. Some coins, like namecoin, are in horrible shape and for many, it's a matter of time before this code aging causes some sort of security issue to be discovered.

Dogecoins are doomed?

Dogecoins are supposedly doomed. The idea is that the block reward is decreasing too rapidly, and the price of dogecoins needs to rise to avoid a 51% attack. I'm not so sure that the developers of dogecoins will just roll over and die, given how large that community is.
More likely is that if the price stays stable and more block reward decreases occur, they will release a fork to stop the reward decline earlier than expected. That will devalue dogecoins significantly. If the hashrate of dogecoins starts to drop, I would get out. I don't think the network is "doomed," but I do think that the only solution to the problem is to devalue coins, and you obviously don't want to be holding when that is announced.

Negative "interest" rates

Apparently, the speculation now is that negative interest rates are going to spread to the rest of the world, and that banks will start charging an account maintenance fee, along with eliminating interest payments. In that case, what is the purpose of using a bank? I won't be keeping a checking account if that happens. Instead, I'll close my account, buy a safe and store cash in it, using banks only to trade stocks. I don't think I spent a single dollar in actual cash for the past year before this, so this is a technological regression.
What kind of world is this where it is a better idea for me to store wads of cash in a safe instead of putting it in a bank, where they actually take money from me?

QuarkChain - Why It Will Blow Up!

QuarkChain is an innovative permission-less blockchain architecture that aims to meet global-wise commercial standard. it provides a secure, decentralized, and scalable blockchain solution to deliver 100,000 on-chain TPS. So basically what this summary is saying for the average Joe’s out there is that QuarkChain is building fast blockchain and smart-contracts by scaling to over 100,000 on-chain transactions per second which is quite a lot. As you know bitcoin can only achieve around 7 TPS while Ethereum only 15. So 100,000 compared to that is quite a leap. It’s even more than VISA at 60,000 TPS.
ICODrops gave it a rating of very high on ROI and Hype which is not far from the truth. With 80,000 telegram members and 15k twitter followers there’s definitely a lot of hype and interest in this coin.
QuarkChain will scale by using a two-layered blockchain system. The first layer applies elastic sharding that will confirm transactions performed on the system. The second layer called root blockchain is set to confirm all the blocks from the 1st layer. With this, they want to achieve 100,000 to 1,000,000 transactions per second in the long term.

Collaborative Mining

With a scale like that, people have been wondering how QuarkChain will stay secure and decentralized. To do that, they will use something called Collaborative mining. The goal of collaborative mining is to design incentive mechanisms and difficulty algorithms so that Hash powers are incentivized to distribute evenly among shards, this ensures that all shards are mined evenly thus the system throughput like TPS increases as the number of shards increases.
The root chain will also have a significant large portion, over 50% of the hash power over the whole hash power of the network. This prevents double spend attack, so basically for a malicious miner to be able to perform such an attack, they’d need 25% of the entire hash power of the system, which would be very economically inefficient. Now you might be thinking well on bitcoin you need 50% of the hash power to be able to perform a double spend attack which is double the amount needed for QuarkChain, how’s that more secure. Well basically in blockchains like bitcoin when the hash power increases or when more miners join the system the expected return of a weak miner grows significantly which causes miners to join different pools which greatly encourages centralization. QuarkChain is going to prevent that by being designed so that weak miners don’t need to join these huge mining pools to be able to collect their rewards. So even with half hash power needed for a double spend attack it’s still more secure than the single layered blockchains like Bitcoin.

Ethereum Virtual Machine

QuarkChain will also implement EVM (Ethereum Virtual Machine) which is the most widely used execution engine for smart-contracts. So Dapps built on EVM can easily be deployed on QuarkChain.
Right now QuarkChain is experimenting with testnet and they’ve already achieved 2279 TPS which shows great progress. Their testnet gets fully released sometime in Q2.

Roadmap

They are currently in testnet stages and plan on going mainnet in Q4 2018. Quarkchain will convert from an ERC20 token to its own blockchain with the ticker QKC after mainnet.

Team

Founded by Qi Zhou who previously worked at Google has built a great team with a lot of talent. Consisting of 9 great team members and 7 advisors that will together build something incredible.

Conclusion

All in all, you’d need to hate money not to look into this project. It’s got everything to succeed in this market. A lot of new technologies with actual use case.
Can’t wait for ICO. You can still attempt to join whitelist by joining the official telegram group(s) that I will link below.

Quark hashrate

I believe in Quark due to the increased security and fast transaction times but the worry I always have with the coin is the dropping hashrate caused by the low block reward combined with zero transaction fees. See http://bitinfocharts.com/comparison/hashrate-qrk.html which shows a steady decrease now most of the mining is over. There is an interesting post on the bitcoin subreddit http://redd.it/22aw8c showing the dangers for altcoins with low hashrates. I'm not sure how quark would be safe from these attacks if it rose in price and popularity again to make these attacks financially worthwhile. I know we now have mining in the wallet but even maxing out an ivy bridge I7 for a few days I couldn't get any. Maybe if the client automatically connected to the nearest p2pool it would produce a few coins a day but would this get a big enough hashrate to protect the coin? The only solutions I can think of would need a hard fork, either an increase in the block reward or turning into a hybrid POS/POW coin. Ideally both to provide the max benefit with minimum forks. Most people would class 2% inflation as low in the fiat world so there is plenty of scope to increase it in Quark. Especially if we're aiming for a fast secure means of paying for stuff rather than a long term savings coin. I'm guessing that merged mining wouldn't be an option due to the difficulty of finding suitable coins to merge mine with that are big enough to make a difference. I'm hoping the devs are looking into these dangers as on the internet there will be a few people with the computing power to trash alt-coins if they can make money out of it and they won't care about the work that's gone into the coin. Sorry if this post comes across as negative but as I'm in the IT security business I'm the sort of person who looks into the worst case scenarios, how likely they are and how to avoid them.

A List of Coins People Find Suspicious | Welcome to the Nigerian Scam 2.0: Mastercoin, Nxt, Ripple (December 25th 2013)

December 25th, 2013
Ripple, Mastercoin, and Nxt all claimed to be Bitcoin-2.0. All are ranked top immediately due to their total circulation numbers or inflated price. Ripple ranked #2, Mastercoin #4, and Nxt #6 as indicated on coinmarketcap.com . It is pretty hilarious to see each subreddit supporters for these coins calling one another scamcoin. Well, guess what, they are either being suspicious or outright scamcoins. Also, check out Mastercoin's pre-sale exodus address of of 5,120.6 BTC. http://blockchain.info/address/1EXoDusjGwvnjZUyKkxZ4UHEf77z6A5S4P
It is a sad day for crypocurrencies. Alternate source without those three: http://www.cryptmarketcap.com/ , however it still has scamcoins listed there (e.g. Quark, Protoshares, Mega, Novacoin, etc.). I will recommend a better listing if one comes around. Anyway I will change the format and will update the list daily/weekly and put it sticky. The full incomplete list is below:

From the "archives" : An Interview with Max Guevera, by K.C. James

Kc James: What propelled you to make Quark? How did it all start?
Max Guevara: I found crypto currencies fascinating when I discovered Bitcoin about two years ago, having a background in programming and a keen interest in finance and economics. From an economic viewpoint, the idea of a currency not controlled by a central authority, but rather by agreement between its users, is an interesting concept. Having followed the "alt-coin" forums on bitcointalk I was always interested in coins that implemented new ideas.
A coin called SifCoin, released on the Russian forums, caught my attention because it used six different algorithms for hashing instead of one. All coins up to that stage (that I am aware of) used only one hashing algorithm. The obvious advantage of having multiple hashing algorithms on top of each other makes is to make the hash as a whole more secure. If one of the hashes is ever broken, there are five more to break. I modified this approach to interweave an additional three rounds of hashing for a total of nine rounds of hashing. These three rounds use a random hashing algorithm, making it even more difficult to break.
Sifcoin used an approach where block reward increases over time, making for a very inflationary money supply. I instead attempted an approach where the coin supply would stay relatively stable over time. This is achieved in two ways, firstly by producing the coins in a relatively short period of six months, instead of years as is the case with Bitcoin, and secondly to have a constant yearly coin production of around a million coins per year.
The yearly million coin production has two purposes, the main purpose being to keep the network secure by permanently rewarding miners, and secondly to make up for coins lost through lost wallets, making for a relatively constant money supply. One economic definition of inflation is an increase in money supply. By that definition, other coins still have a high inflation rates, as many new coins are still mined, while Quark is almost at the stage where the one million coins will produce around 0.5% inflation for the first year. Ever since its release Quark had good community support from various fantastic members who ran forums, developed a GPU miner and provided other services.
KJ: Particle physics has been a fascination of mine for awhile now. So, naturally, the first thing that really caught my attention with 'Quark’ was it’s unique name, and proton-like logo. What was your initial reason for using an elementary particle as the name and logo for a crypto-currency?
MG: Yes, the name was inspired by the sub-atomic particles and the logo was inspired by a representation of the quarks in a proton. There is the similarity in that there are six types of quarks and six hashing algorithms used by Quark.
KJ: Quark went from being just another crypto-currency in a long list of other alt-cryptos, to the #4 spot on CoinMarketCap.com, in a staggeringly short amount of time. How surprised were you by Quark's sudden rise in popularity?
MG: I was extremely surprised when it approached the top 10 coins on CoinMarketCap. Alt-coins and exchanges have received a lot of media coverage recently. This caused an influx of people registering at exchanges like Cryptsy and caused a general rise in the price of most alt-coins. I guess Quark's secure hashing made it stand out from other coins.
KJ: One of the most persistent and cliched criticisms coming from Quark-naysayers in the crypto-community, is the accusation that ”Quark has been pre-mined.” Could you elaborate on why this statement is false, and if it's not false, then could you explain how this is a non-issue?
MG: Generally the term "pre-mine" in the alt-coin community refers to mining a coin before releasing it to the public, or where a coin has a special block in the beginning (usually block 1) that gives a large reward to the developer. Neither of these apply to Quark. Quark was released on bitcointalk, the most active alt-coin community on the web, with only the genesis block mined. During this period on the alt-coin forum, many new coins were released, sometimes multiple coins a day.
The response to Quark's release was also a big surprise. Within minutes the seed nodes were maxed out with hundreds of connections and additional nodes were provided by other members of the forum. The coin was listed on multiple exchanges relatively soon after its release, so I think this allowed for a relatively wide distribution of coins before the recent dramatic rise in price.
KJ: In layman's terms, could you explain how Quark is better than Litecoin and/or Bitcoin? What makes Quark different and more worthwhile than those two leading crypto-currencies?
MG: I would not like to say one crypto currency is better than another, since these are relatively early days in the cryptocurrency world. Both Bitcoin and Litecoin have huge communties, which I personally believe is a big reason for their success. Quark offers an alternative, arguably more secure hashing algorithm than Bitcoin and Litecoin, quicker transaction processing and a mining model that aims to have a virtually constant coin supply.
KJ: Quark's transfer time is said to be the fastest and most secure out of all the other crypto-currencies in existence. Could you explain, in layman's terms if possible, how/why Quark is faster and more secure than other crypto-currencies like Litecoin and Bitcoin?
MG: The main security improvement in Quark over other crypto currencies is its hashing algorithm. It makes it less likely that transactions blocks could be compromised if one of the hashing algorithms is broken. Given recent revelations on how much influence government agencies had over the design of cryptographic standards, it might not be inconceivable, although highly unlikely, that some algorithms may have been compromised.
Quark's hashing algorithm also makes it very difficult to build custom machines (ASIC) that could out-hash a large network of PCs. The hashing algorithm is not the only factor in the security of a coin. There are other factors like checkpoints, the size of the hashing network and the age of a transaction. Bitcoin is currently the leader in hashing power. With its high hashing difficulty, it does have security advantages over the other coins currently out there.
KJ: Where would you like to see the Quark community take the currency?
MG: To a strong, secure, widely accepted crypto currency with a wide range of products and services offered in Quark.
KJ: In your opinion, how important is the community that is currently being developed around Quark, to Quark's overall success?
MG: The community is essential. A currency only works if it is widely used and accepted. Governments have the ability to enforce a currency on its citizens, but crypto currencies need the voluntary acceptance of its users.
KJ: What, in your mind, would make Quark a success? Would you like to see Quark overtake Bitcoin one day? Do you think a feat of that sort would be possible for Quark?
MG: Quark will be successful if a strong community develops around the coin, and this has already started to happen. Some very talented and enthusiastic individuals have started doing great work to improve Quark and its infrastructure. I think there is place for multiple crypto currencies to co-exists. Certain currencies offer advantages over other and may be more suited for certain purposes. Quark offers quick transactions, a relatively constant money supply and a secure hashing algorithm.
Bitcoin is still by far the leading crypto currency, in terms of community, recognition, and security. But the crypto-currency world is still in its infancy, and who knows what the future might hold.

Mandatory DigiByte Update Friday 7PM UTC

Update will be released around 7PM UTC time this Friday. (2PM Eastern / 11AM Pacific)
Here is what we would like to accomplish with the upcoming update:
1) Change block difficulty re-target to 1 minute to resist multi-pool mining & dumps to help steadily build the price.
2) Add transaction message support.
3) Update to latest version of Bitcoin/Litecoin client.
4) Reduce the block reward by 0.5% every 7 days starting at 8000 DGB.
Gravity Well vs Re-Target:
From our research we can not see what if any advantage the gravity well would offer over simply changing the re-target time to 1 minute. In fact, the gravity well would actually allow for more coins to be mined for a few minutes after a dramatic instant hash increase when compared to changing the difficulty re-target to 1 minute. The gravity well implementation would complicate things for us and cause issues with our Android wallet. Since both achieve the same desired result (ending multi-pool driven hash swings & coin dumps). We would like to travel down the path of least resistance.
Built in Wallet Update Feature:
Xploited had the best answer to this. Isn't the point of a crypto currency to avoid centralization? By implementing a single location that all wallets can update from we are also implementing a single point of failure to the network that could potentially be taken over by an attacker who could cripple the network. We want to make sure DigiByte will remain strong and resilient to attacks.
Block Reward Increase:
The idea of producing most of the coins right away and entering the deflation stage as soon as possible is very interesting to think about. However, at this point we feel there are several reasons why we should not go this route. Had we talked about this before we launched it might be a different story, but not now that we are way beyond launch.
It would be very unethical and unprofessional of us to increase the block reward. This would cause an immediate decrease in price and as such it would be very discourteous to current investors. Some of which have invested several thousand dollars worth of Bitcoin into DigiByte.
Another reason for not mining all the coins right away is mining itself. Mining keeps a coins network strong. In order to keep miners mining, they need coins to mine. Just look at Quark, many miners have jumped ship and the threat of a 51% attack from bot nets continues to increase. Miners should and do deserve to be incentived well into the future.
Block Reward Decrease:
We are not looking to do anything dramatic here. Instead we are looking for a solution that will benefit everyone. Miners, current investors and future investors.
We will reduce the block reward by 0.5% every 7 days. This gives DigiByte over 20 years of profitable mining. A nice half percent decrease is much easier for people to calculate and for us to market. Reductions will occur on Fridays to give a slight psychological boost going into weekend trading.
Examples: Two Fridays from now the first reduction will occur. It will go from 8000 DGB to 7960DGB
Week: 1 Reward: 7960
Week: 2 Reward: 7920.2
Week: 3 Reward: 7880.599
Week: 4 Reward: 7841.196005

    1. Great analysis by singularity and jessquit on how anti-btc trolls shifted: "suddenly last year they all disappeared, and a new type of bitcoin user appeared who were fully in support of bitcoin but they just so happened to support every single thing Blockstream and its employees said and did." (102 points, 50 comments)
    2. Don't fall for EDA Dragons Den FUD. EDA is a powerful weapon that could kill off or cripple the segwit chain for good. Legacy coin has no EDA crash barrier as this article explains. This is why small blockers use FUD us to disarm the EDA (78 points, 118 comments)
    3. Roger Ver CEO of bitcoin.com says that from his point of view the segwit2x split just gives him more coins to sell for the Bitcoin Cash version which he thinks is the more useful Bitcoin @3min41s mark (71 points, 33 comments)
    4. Proof the new Dragons Den plan could be to try to split BCC with an EDA change. Mrhodl is confirmed Dragons Den, and Cobra Bitcoin is the leader of bitcoin.org which is making enemy lists for big block supporting businesses. (70 points, 47 comments)
    5. Right now segwit2x (BT2) is trading for $1143 and segwit1x (BT1) is $3070 on Bitfinex futures markets. Even with not the greatest terms, you would expect 2x to be much higher. I believe this bodes well for BCC. (61 points, 112 comments)
    6. The other day people were suggesting we do an EDA change before the November 2x fork. Here is why I think that is a terrible idea, and why we should only consider EDA change AFTER the 2x fork. (58 points, 40 comments)
    7. "Nick, Adam and others saw the flaw in the system being that they could not ensure one vote one person.. The flaw in that reasoning is assuming that one vote one person was ever a goal. Miners act economically not altruistically." (57 points, 14 comments)
    8. Original chain is now only 4.8% more profitable than Bitcoin Cash chain after the most recent EDA adjustment on BCC. Very normal blocktimes. Where is the EDA dragons den FUD now? (53 points, 33 comments)

    1. Bitfinex announcement about issuing BT1 & BT2 "Chain Split Tokens" to allow Futures trading. (BT1 = Segwit1x; BT2 = Segwit2x) (172 points, 173 comments)
    2. By proving that it can be done (getting rid of Core) this will set a HUUGE precedent and milestone that dev teams and even outright censorship cannot overtake Bitcoin. That will be an extremely bullish occasionfor all crypto. (149 points, 84 comments)
    3. Bitfinex is going to call Segwit2x coins "B2X" and let Core chain retain "BTC" ticker symbol. Bitfinex is therefore calling Segwit2x an altcoin and Core the "real chain". (138 points, 70 comments)
    4. The goal of all the forks appears to be to dilute investment in the true forks: Bitcoin Cash and Segwit2x. A sort of Scorched Earth approach by Blockstream. They are going to try to tear down Bitcoin as they get removed. (35 points, 11 comments)
    5. Blockstream be like (10 points, 11 comments)
    6. In light of all these upcoming forks, we need a site where you can put in a BTC address and it checks ALL the forks and says which chains still have a balance for that address. This way you can split your coins and send coins carefully. (6 points, 6 comments)

    2. The very objective article "Bitcoin is not ruled by miners" on the "bitcoin wiki" was added by theymos on 8th of August this year. Nothing strange to see here, just an objective, encyclopedia-quality overview! (155 points, 58 comments)
    3. According to Crooked Greg, Jeff merging opt-in replay protection is "alarming", because it must mean Jeff wants to blacklist people's addresses too. Core devs keep lying and manipulating to stir more drama and further the split in the community. Disgusting! (75 points, 16 comments)

    4. BCC Miners, two EDAs have locked in. This will reduce mining difficulty to 64.00%. If you are aiming to achieve profit parity, you should start mining after the next EDA (in 2.5 hours), because then the difficulty will be at 51%, which gives profit parity on both chains and steady block rate. (9 points, 14 comments)
