North America’s BTC ASIC Miner (ePIC Gen_1)

How it started

 

Not too long ago, ePIC rolled out the SC200 Mining Rig for the Siacoin network. This milestone was the culmination of hard work and perseverance of a small, but talented team. Now, looking back, we are so proud of this achievement. It is easy for industry arm-chair quarterbacks to downplay the efforts it takes to design and to produce a mining rig. They would often say, “it’s just a few lines of code.” That may be so for an algorithm, but math alone is not enough to make a profitable mining rig.

 

From concept to reality, the path to producing a product requires many steps:

 

  • designing, fabricating, and testing the mining ASIC
  • integrating all the components on the PCB
  • validating the performance and power of the hashboard
  • modeling the air flow and heat dissipation through the chassis of the rig
  • developing firmware to control the performance of the rig
  • writing software APIs to communicate with the external world
  • implementing factory tests for quality control

 

We encountered many challenges along the way, and we took them all in stride, making them into valuable learning opportunities.

 

What has happened in the last 12 months?

 

Customer Engagement

 

Not only did we learn how to bring a product to market from scratch, but along our journey we learned a tremendous amount about our mining customers — especially, their challenging and ever-changing requirements. To that end, we introduced ePIC’s Universal Mining Control (UMC) and companion firmware. These ePIC offerings are compatible with mining systems and enable enterprises to maximize the full potential of their mining fleet. The UMC and firmware will allow mining fleets to respond quickly to fluctuations in their requirements, most notably, the changes in power. Fleets will be able to ramp up and ramp down quickly accordingly. Enterprises can respond to power costs, coin prices, curtailments, and so on with the API to control performance and efficiency.

 

 

Supply Chain

 

As a company that produces physical products, we understand the critical importance of supply chain management. The past two years have emphasized this. We have already built strategic relationships with key suppliers, such as TSMC and ST Micro. As we grow our business, we have engaged multiple vendors, and even collaborated with them to make improvements. One such example is with PSUs — to make them more efficient while keeping the costs reasonable. By taking ownership of the supply chain, from materials to place of manufacture, we ensure that our products are robust with a low failure rate.

 

 

System Integration

 

We have a track record of bringing all these things together. But more than that, we understand how all the components work with each other through fine-tuned system integration. From the semiconductors to the software, from the PSUs to the heat dissipation, each of these components has a number of input variables that must be considered such as operating frequency, voltage, output performance, power efficiency, and so on. We can build systems that are tightly integrated, but have the agility to respond to the customer’s requirements, which are usually driven by market dynamics.

Intel Blockscale

 

With everything that we have learned and with all the skills and know-how we’ve developed, we are excited to be working on a Bitcoin miner using Intel’s Blockscale chip. Our talented team is well-equipped to design and to deliver this system. Intel’s advanced technology on Blockscale requires experienced engineering.

 

The Blockscale chip has a wide operating range. This allows for flexibility, but it also creates serious technical challenges. The chip has temperature and voltage sensing capabilities, which we can read, among other parameters. We can then program the chip to find the “sweet spot” for hashing. But, as one can imagine, the temperature and voltage will fluctuate, and many adjustments will need to be made to keep that chip operating in a stable state. All this is for just one chip.

 

Now, scale this effort to the multiple hundreds of chips in a single mining system. It would be simplistic to think that each chip would be operating identically on a hashboard, and treating them all the same would not maximize the full potential of the hashing power.

 

Now, scale this effort again, to the thousands of mining rigs that are in a fleet of miners. The engineering effort is enormous.

 

 

True to our Fundamentals

 

We’ve come a long way over the last few years. We’ve grown organically to manage sustainable growth. We’ve tackled new and exciting challenges. Through and through, ePIC’s guiding principle remains the same — bring together world-class engineering and focused operational excellence to deliver dependable, robust and reliable technology.

 

Full-system burn-in

 

Final words

 

Stay tuned and imagine where ePIC can be at our next inflection point.

 

Will it be our Gen_2 BTC miner? Will secure real-time settlements on the blockchain be the next driver for high bandwidth and low power designs? Will better HW infrastructure accelerate the adoption of a decentralized internet (aka Web3)?

 

The constant will be the build-outs from ePIC into these emerging blockchain markets. We are ready and we think differently.

What It Takes to be a World-Class ASIC Hardware Provider

The recent pandemic has made us look at things differently, focused our attention on critical infrastructure, and forced us to adapt to new challenges. As a response, old ideas have come back in fashion again showing how foundationally important they are. While new ideas have accelerated ahead spurring on important innovations.

Take for example virtual home workouts. Exercise is an enduring element of daily life. New workout routines and training programs have been created for home, but delivered interactively and streamed in real time. The content might be new, but adoption and success of this new paradigm depends on fast and reliable internet access. Internet access has never been more crucial — so much so, that it is a de facto essential service.

Good system design will lead to dependable infrastructure that is reliable and robust.

 

Emerging blockchain hardware: ASIC mining

In response to cryptocurrency markets, various companies, often with inadequate experience, have produced ASIC miners. In the rush to capitalize on the market, robust system design is often an afterthought by some companies. There could even be an argument that this aspect is completely overlooked. Producing an ASIC is more than just writing a few lines of code.

The adoption and success of a mining operation depends on full-system thinking, end-to-end reliability, and close collaboration with mining farms.

Who can step up to these challenges?

 

Some of the recent ASIC hardware providers have been struggling with poor integration into the mining infrastructure, field failures and major gaps between specifications and real-life results. While others have just disappeared.

But there are also new players emerging.

 

Introducing ePIC Blockchain Technologies

 

This brings us to a promising North America based start-up, ePIC Blockchain Technologies.

This high performance, experienced team applies the best practices for engineering design and operational excellence from the telecom, PC and mobile industries to the ASIC hardware mining space.

SoC design and system design are highly specialized fields of engineering. Combining these specialized design skills with a deep understanding of architectural trade-offs and blockchain algorithms is the recipe for success.

At its core, this is the team inside ePIC.

To date, the industry has been preoccupied with nano-marketing name dropping. It is fashionable for companies to tout their ASIC based on the technology node. However, that may be a distraction from what is lacking.

The end-customer should not care which node their ASIC is manufactured on. What matters is the quality of the design.

The proliferation of multiple variants, 5–6 in some cases, of a manufacturer’s product is another interesting artifact of the current suite of mining providers. Is it a deliberate marketing plan for different price-points? Or is it a design and manufacturing flow that is not well understood and controlled? Could it be a very wide cross-section of performance and power outputs that are produced and pushed out to the unsuspecting customer?

 

What really matters to the ASIC mining customer?

The answer is simple. Get the job done right and on-spec.

Launched recently, the SC200 miner is the product that showcases ePIC’s world-class system design capabilities.

 

From ASIC to mining rig: a visual glimpse into bringing a product to market

Work doesn’t stop just because silicon is in hand.

Full understanding of the system is required to bring a quality product to market. Having a chip that works in isolation is not enough. Having both the depth and breadth is what distinguishes ePIC from other companies.

Here are a few examples of the behind-the-scenes due diligence taken prior to the introduction of the SC200 to the market. And it serves as a macro lens into the systematic approach that is needed for future generations of ASIC hardware miners.

Leading the way

In any industry, what distinguishes the leaders is straight forward — “what they deliver just works as advertised”.

 

ePIC Blockchain Technologies is bringing this philosophy and track record to the ASIC hardware blockchain mining industry. World-class engineering design and a maniacal focus on operational excellence are ingrained in the ePIC culture.

To be called out so early as the “Dyson of ASIC Miners” is a distinction to be proud of and the team will press on to provide dependable, robust, and reliable technology.
