Recently, there was a lot of talk about ASIC, Ethereum, video cards (GPU), AMD and Intel, all in the same breath and all in relations to Ethereum mining. What kicked this off was because Bitmain recently announced they will launch the AntMiner E3, sometime later this year, which is meant for mining on the Ethereum blockchain. This supposedly has caused dissatisfaction within the Ethereum mining community based on speculations of what the impact of introducing ASIC miners will be.
The majority of people who are not invested in either the mining process, hold ETH or any other digital currency that runs on the Ethereum blockchain, they might be asking themselves how this impacts them, and should they even care about it? Well, it is a good question! And unfortunately not one we can answer, but by giving you more information on the various subjects, you might just be able to do that yourself. Just for clarification, this will not be an in-depth technical article.
What is mining, and what is a miner?
First of all, mining only applies to blockchains that as part of its consensus protocol use Proof of Work (PoW) to create and validate a block. A blockchain that i.e. uses Proof of Stake (PoS) as part of its consensus protocol cannot be mined upon. There are other types of consensus protocols out there and even variations of the mentioned protocols ? we will not cover those in this article though.
In simple words, mining is the process of creating a block, its cryptographic hash value and show that you actually put some effort into creating the block ? hence Proof of Work. Very simplified put Proof of Work, or PoW, is done by creating a block?s cryptographic hash value which has to be less than the previous block?s cryptographic hash value. So a miner is a hardware which is used to calculate the cryptographic hash value. We will take a look at the hardware in the next part of this article.
Miners compete with each other to be the first one to create new blocks. This translates into the faster you can calculate the cryptographic hash value the more likely you are to be the first one to complete the task and receive the block reward, ?if any?, and the transaction fee. ?If any? is because currently miners will receive a block reward, but in the future, they will have to rely solely on transaction fees.
The block reward consist of a fixed amount of coins which is taken from a pool the creators reserved for use as an incentive to make it financially attractive to mine on their blockchain ? you may have heard people talk about block reward subsidy, which refers to this pool of coins. These coins were not released to the public but will be released through the block rewards ? hence the term mining. The block reward decrease in regular intervals set forth by the creator of the blockchain, until all the coins are released ? at which point the only financial incentive for mining will be the transaction fees.
But for now miners get a subsidized block reward, and we are talking big money here. At the time of writing this article, the ETH block reward was almost $1800 per block translating into the total block reward payout for the last 24hours was just over $10.6 million US dollars, according to bitinfocharts.com.
As mentioned earlier, computing power is everything when it comes to completing the task of generating a new block and be able to claim the block reward. While solo mining is possible it makes more sense to pool resources with other miners as it not only increases the total combined hash rate* but also increase your chances of claiming a part of the block reward. This is why you have a number of mining pools that are either run by a group of individuals or mining corporations.
*Hash rate is measured in X Hash per second, where X can be Mega, Giga, Tera and so on. I.e. Mega hash per second is written as MH/s.
The need for speed, literally speaking
So let?s look at the hardware part and the differences between a CPU (Central Processing Unit), GPU (Graphics Processing Unit) and ASIC (Application Specific Integrated Circuit).
The Ethereum blockchain probably has the best ratio of ?easy? to mine to profitability, which makes it attractive to mine at home on conventional off-the-shelf hardware such as a CPU or GPU.
Even though CPU?s today are both powerful and fast enough for computing complex cryptographic algorithms they are not necessarily ideal for the task.
The best way to describe why is to compare it to someone with attention deficit, on speed. I know this was not the nicest way, but my point is that it was designed as a multi-purpose-decision-making device that cannot focus and finish one task at the time ? and you wouldn?t want that either as it would mean you?d have to sit and wait for it to complete its current task before it would move on to the next.
Instead, it will be all over the place to keep all the processes running on your computer alive, which slows the hash rate down ? and again there is a sense of urgency involved if you want to have any hopes of being able to lay claim to a block reward.
With the GPU it gets better. GPU?s today are more broadly designed which allows them to accelerate certain computational workloads. Architecturally GPU?s have more cores than CPU?s which means that it has the potential of accelerating some software by 100x, and still be more power and cost efficient than a CPU. Though the GPU was not exclusively designed to calculate cryptographic hashes, it has the focus the CPU is lagging making it a better choice in achieving a higher hash rate.
This is why there has been a huge rush on video cards for quite some time. This has translated into the price on video cards has gone up in an effort to try and slow consumption for mining purposes, because it hurt availability to the ones that it was intended for, the video gaming community. The most ?tragic? part of this story is that both mining and video gaming popularity picked up at almost the same time, causing this huge rise in demand for video cards.
On the not off-the-shelf side, we find ASICs. An ASIC is a ?dumb? chip that has been designed to do, normally, one task only ? ?dumb? refers to it will not make any decisions; it will just do the task it was programmed to do, at an extremely high speed. ASIC has been used in enterprise-grade networking equipment such as routers, switches, and firewalls for decades, to move network packets around – fast.
When the ?Next Generation Firewall (NGFW)? was introduced Fortinet, a cybersecurity company, re-tasked their ASIC to do SSL decryption ? for those who don?t know, and the paranoid, it means that you can look into, most, encrypted packets and see exactly what they contain. The point of bringing this up is not to scare the paranoid, but to highlight the use case of ASIC to solve a cryptographic task at high speed.
The reason ASIC is not an off-the-shelf product is that it has a high R&D cost, and a very limited scope of use ? also it cannot be reprogrammed once fabricated. However, it is ideal for blockchain mining especially as the block creation difficulty increase over time, adding even more emphasis on a high hash rate speed. A lower hash rate speed will result in a slower block creation thus transactions will take longer to confirm.
One downside to ASIC is that it consumes more power than a CPU and even a GPU, which translates into it generates a lot of heat. What that means in words is the fan(s) will be extremely loud ? almost like a jet taking off give or take an engine. Besides the electricity bill, the noise is a big reason for why you do not want to have an AntMiner sitting in your living room. So unless you have a well sound insulated cold spare bedroom, and no wife to complain about your AntMiner needs its own room, and your in-laws have to sleep on the couch when they visit; then you might want to look into some alternative mining options. If anyone has gotten a divorce on this account, then we would very much like to hear from you and write your story!
That AMD and Intel have been mentioned is because they are the manufactures of the GPU?s used on the video cards used for mining, and of course gaming. The odd thing here is that no one has mentioned the video card manufacturers such as ASUS, Gigabyte, MSI, and others ? or for that matter the other component manufacturers for memory modules, power supplies and so on. Why this may matter to you we will look at next.
Video card industry
So even if you are not involved in cryptocurrency, be it mining or owning it, you may still be affected if you are an investor in any of the companies involved in the process of manufacturing the GPU?s and the video cards. The boom of demand for video cards, and their price skyrocketing means more earnings for those companies ? reports indicate that the cryptocurrency mining market was worth $776million in 2017. This number excludes the other component manufacturers, so the total is well beyond the reported number. When and if the demand for video cards normalizes these earnings will drop off and most likely be reflected in the respective companies share price.
Not going into the financials here, the key takes away is that mining was a new a marked that opened up and helped drive growth for the component industry as a whole. With this market going away they need to go back and continue to grow their regular markets ? or find a way to stay in the mining market.
The upside to this is that we might see the price on video cards go down unless the industry decides that the current price level is just fine and since the consumers are used to pay the premium there is no immediate reason to lower the prices. We just have to wait and see what happens.
Ethereum (mining) community
Finally, let?s take a look at the Ethereum (mining) community to try to understand why or what is causing dissatisfaction amongst the miners and its users.
An important thing to understand about the various cryptocurrencies, the founders, and their communities is that they tend to achieve an almost cult-like status. Their supporters are devoted to the coin and almost worship the person they see as the leader of a particular coin; Ethereum is no different in this way.
A good example of this is the Ethereum hard fork, which divided into Ethereum and Ethereum Classic and saw the community divide with the users rally around the leading figures. The reason for the hard fork of Ethereum was to restore coins that had been taken from its users, but it was never meant to split the community as it did, due to disagreement within the community. Could a yet another divide and a new Ethereum coin be on the horizon, based on the call-to-action the community is suggesting?
First and foremost it seems the community just wants to stop Bitmain?s ASIC rig from entering the mining scene ? though the real question here being is it the use of ASIC they oppose or Bitmain itself? That question can only be answered by the community, so it will remain unanswered in this article.
But let?s look at one of the suggestions, make alterations to the code to render the ASIC useless. Is this a feasible solution or even possible? From a feasibility point of view, it seems like a long shot and something that will turn into a cat and mouse game. Will it even be possible to make changes that will render the rig useless without knowing how it was put together? Remember the ASIC is ?dumb? it?ll just do what it is told to do, so if something else can interpret the change and translate that into a task the ASIC can do then this option is off the table. Keep in mind Ethereum is open source, Bitmain not so much ? so it kinda leaves Bitmain with the upper hand here.
Fact, Ethereum is working and testing on a hard fork. They have been working on a project named ?Casper? which will change consensus from PoW to PoS, and as mentioned at the beginning of the article PoS is not minable. Problem solved ? or is it? Well not being able to mine most definitely stops the Bitmain ASIC rig in its track right there ? along with the rest of the mining community one may add. This raises yet another question, does the community want to continue mine or are they happy about staking?
Whatever the answer may be to that question if the aim was to keep the entity Bitmain ?away? this won?t do that. Staking is the process of which you own the coin in which you want to stake, the more you own the higher your stake, read more of a trusted source you will become. On a side note, Bitmain?s profit for 2017 was somewhere between $3 to $4 billion USD, just saying.
Because there seem to be a divide around how or what to do and stop, will Ethereum end up in a D?j? vu situation with the upcoming hard fork?
Digging further around in this will not bring us closer to an answer. So let?s just conclude by saying that we may not have found an answer, but hopefully, you have a better picture of what is going on. I guess we just have to sit back and watch as the events unfold.

Inside the Mysterious World of Bitcoin’s Mempool
Blocknative’s Mempool Explorer lets you explore the transient space where Bitcoin transactions are suspended in limbo.
- Blocknative has launched its Mempool Explorer to help understand mempool data.
- Transactions pass through the mempool before they reach the Bitcoin blockchain.
- The Mempool Explorer promises to democratize access to mempool data.
But what is the mempool? It’s the gateway to Bitcoin’s blockchain and many others. Before any transaction is written on a blockchain, the information first enters the mempool. There it sits, almost in purgatory, waiting for a Godly miner to select it and inscribe it into a block—or discard it forever. But the very nature of this in-between world, which differs for each miner, has always made it challenging to analyse. And it is often exploited by bad actors with the expertise to see things the rest of us can’t.
“At a minimum, our platform represents sunrise in the Dark Forest. The alpha predators are still operating, but now everyone can monitor their actions,” Matt Cutler, CEO and co-founder of Blocknative, told Decrypt.
The main problem is that the Bitcoin mempool is built upon the shifting sands of pending Bitcoin transactions. As there is no one central source of mempool data—each miner has their own version of events—it is difficult to gather and utilize this data. This, in turn, makes it hard to take a reliable snapshot of events, and present them to developers.
“It is pre-consensus by definition. It is constantly changing—literally at a sub-second level,” said Cutler.
How the Mempool Explorer works
The Mempool Explorer tries to make sense of the pre-consensus data found in the mempool, making it accessible and easy to analyze.
In the mempool, pending transactions are ordered, fees are prioritized, and new blocks are sent to the blockchain. The Mempool Explorer examines this data and makes it available to developers. Using the Mempool Explorer, users can track pending transactions, monitor exchanges, and share mempool data with others. In other words, it is a purpose-built environment for crunching data before it hits the blockchain.
The Mempool Explorer works as a global network of nodes, all enabling the Explorer to detect and record data on the mempool in real time. The Mempool Explorer can record more than 7 billion Ethereum mempool events in just one month. That is over 2,000 events per second on a 24/7 basis.
How mempool data fights frontrunning
While mempool data is tricky to get hold of, it’s very useful for several different purposes.
One of its main, albeit shady, uses is for frontrunning. Frontrunning is a way of making trading decisions based on knowledge of future events, similar to insider trading. And traders use frontrunning to get ahead of people on decentralized exchanges, typically on the Ethereum blockchain.
Alex Svanevik, CEO at Nansen, told Decrypt, “There’s certainly demand for mempool data. Trading in traditional finance is often a latency game, and crypto is no different,”
Here’s how frontrunning works when blockchain is involved. Since blockchain data is public, someone watching the mempool can see a trade being made and then make the same trade, offering a higher transaction fee. Since miners tend to pick transactions from the mempool that have higher fees (so they make more money), this means the later transaction is more likely to get included in the block—and the person gets ahead of the trade.
Until now, only some individuals use such techniques. “Today, these techniques are the domain of a well-equipped, and well-financed, elite few. Everyone else is at best a spectator to their actions – at worse, unaware,” said Cutler. This means general people using decentralized exchanges are often subject to frontrunning—but may have no idea.
Now anyone who uses the Explorer will now be able to fight back.
“Any adversarial action that goes on chain must—just like everything else—first traverse the mempool. So our platform can give concerned parties advanced warning that adversarial actions are underway,” Cutler added.
It’s time to embrace the mempool.
Fintech Firm Fasset to Launch Zero-Trade Fee Crypto Trading Platform for Countries in the Gulf Region
A new cryptocurrency trading platform is gearing up to offer zero-fee trades to users in six countries in the Gulf Region. Announced on Thursday, the platform Fasset Exchange (FEX) has started sign-ups for its private beta and is planning a public rollout later this year.
Bitcoin short-term Price Analysis: 24 September
After being rejected under the $11,000-mark, the last 48-72 hours have seen Bitcoin survive a period of bearish turmoil. With the cryptocurrency’s price consolidating near $10,300 at press time, some degree of recovery was observed on the charts. However, the resistance at $10,412 continued to hold out. A look at Bitcoin’s charts revealed that a period of high volatility may be incoming for the world’s largest cryptocurrency.
Bitcoin 1-hour chart
The 1-hour chart for Bitcoin, particularly, pictured a rising wedge pattern, at the time of writing. However, the chances were that the pattern will not hold true in terms of a breakout over the next few hours. Following the drop at $10,200, it is more likely that the valuation will exhibit more sideways movement and possibly re-test the resistance levels at $10,412 and $10,562.
The 50-Moving Average needs to be considered with respect to being a strong overhead resistance, but a quick burst in buying pressure can lift the crypto’s price well above the Moving Average. Further, the Awesome Oscillator indicated that despite the presence of bullish momentum, it wasn’t enough to affect a reversal on the charts.
Bitcoin 2-hour chart
While the 1-hour chart was riddled with confusion, more clarity was seen on the 2-hour chart. The two-hour chart explained the possible market structure for Bitcoin’s movement over the coming days, rather than plotting an accurate price movement. As observed in the attached chart, the market structure was hardly broken, at the time of writing, with Bitcoin possibly going to move between the parallel channel before registering another flash crash to the support level at $9980.
The transition might not follow exactly with respect to the green line, but structurally, a re-test at $9980 before another leap north should be expected.
The Stochastic RSI was completely bullish in the short-term, hence, the price can rise to $10,560, before heading south. After reaching its peak, the orange line should undergo a bearish crossover at the overbought position as the selling pressure takes over once more.
