The Bitcoin halving is a big event for miners, marking when the block reward for mining Bitcoin is cut in half. A block reward halving occurs every four years and is designed to slow down the issuance of new bitcoins until it eventually hits 21 Million. With another halving around the corner, miners must look at ways to stay profitable even when their rewards get smaller. This halving epoch marks a move from 6.25 to 3.125 Bitcoin mined per block. At current prices, that’s a revenue reduction of $27 million per day for the industry, not counting fees.

To deal with the challenges the halving brings, Foreman can offer essential tools to help miners maximize their site resilience. We’ll cover three key ways to do this: using Firmware to make mining more efficient, cutting costs by making intelligent decisions in real-time, and increasing revenue by taking advantage of changes in electricity demand or Demand Response.  These strategies can help miners stay profitable when the halving reduces their rewards. Here are three ways to maximize revenue with Foreman going into the halving.

1. Increase Efficiency with Firmware

The number one way to help maximize revenue is by installing custom firmware. Firmware adjustments ensure that each mining chip operates at optimal frequency and voltage by enabling precise tuning and optimizing ASIC miners. Optimization not only maximizes the hash rate or the mining power of the hardware but also minimizes energy consumption. As a result, miners can achieve a higher output of Bitcoin for a lower input cost, effectively increasing the profitability of their mining activities. In the context of the Bitcoin halving, where mining rewards are reduced, the ability of firmware to squeeze out additional efficiency becomes even more valuable. It offers miners a competitive edge in maintaining and increasing their revenue streams despite the challenges of the halving.

Foreman simplifies the network installation of firmware across numerous ASIC miners, enabling miners to update and manage firmware on multiple devices simultaneously and at scale. The ability to batch firmware updates is crucial for large-scale operations, where updating each miner individually would be time-consuming and impractical. By facilitating swift firmware updates, Foreman ensures that all mining hardware operates with the latest efficiency improvements, helping miners maintain optimal performance and maximize revenue, which is particularly important as they navigate the challenges posed by the Bitcoin halving.

2. Strike Price-based Cost Avoidance

During volatile electricity price fluctuations, Bitcoin miners can significantly benefit from a strategy known as Peak Avoidance. Peak Avoidance is an essential approach for miners on variable power. It involves temporarily halting mining operations when electricity prices spike above a predetermined threshold, thereby preventing mining at a loss. A case study in the ERCOT market demonstrated how utilizing Foreman’s automated curtailment feature, based on a machine strike price, enabled miners to avoid high-cost periods, leading to substantial cost savings. The projection of S19J Pro Revenue at 30.5 J/Th will go from $120/Mwh to $60/Mwh after the halving.

The above image compares two scenarios over the past six months. The top is the 6.25 block reward from the halving, and the bottom scenario is a 3.125 block reward as if the halving happened six months ago. With decreased profit margins across the board, older machines will cross the profitability line more often, thus the need for programmatic curtailment.

Methodology:

• Compares 6.25 block reward (top) to 3.125 block reward (bottom)
• Previous six months of real-time index pricing in ERCOT for cost
• Profit is based on the 30.5 J/Th efficiency
• Data points collected are only when the 3.125 block scenario is unprofitable.

The bars only show adverse pricing events for the 3.125 block reward over the past six months. The result is a negative $14,000 per MW on the bottom chart. Scale this up to a multi-MW facility, and that has the possibility of significant losses. The above chart of the 6.25 block reward shows the same pricing events as the 3.125, but overall profitability is a massive change. Over the same period, the pre-halving S19J Pro was much more profitable. It is profitable despite having some adverse pricing events itself. All else being equal, as the revenue gets cut in half going into the halving, there will likely be many more negative profit scenarios that need to be addressed.

Cost avoidance becomes crucial for miners operating in index or real-time pricing areas, such as ERCOT and other Independent System Operators (ISOs). Older mining hardware tends to be less efficient and will find profitability margins increasingly thin after the halving. Given their lower efficiency, these machines are likelier to tip into unprofitability, especially with high electricity prices. These variables emphasize the need for strategic, operational adjustments to mitigate losses and maintain viability in the competitive mining landscape. By leveraging intelligent tools like Price Avoidance, miners can navigate the demand spikes of real-time pricing, ensuring their operations remain profitable even under adverse conditions.

3. Increase Revenue with Demand Response

Demand Response (DR) strategies are essential for balancing electricity consumption with supply, enhancing grid stability and efficiency during demand fluctuations. Bitcoin miners excel in this landscape thanks to their operational flexibility, enabling swift adjustments to energy usage that align with grid demands. Their rapid response capabilities help stabilize the grid and elevate Bitcoin mining to a vital role within the energy sector, outperforming traditional industrial responses.

By engaging in DR programs, Bitcoin miners capitalize on their ability to scale down operations quickly during peak demand times, such as during extreme weather conditions, thus relieving stress on the power grid. These programs, offered by grid operators and utility companies, provide financial rewards for reduced electricity use when most critical, turning potential operational challenges into profitable opportunities. The miners’ proficiency in navigating these DR programs highlights a mutually beneficial relationship between the flexible nature of Bitcoin mining operations and the evolving requirements of the modern power grid.

Moreover, strategically pausing mining activities when electricity costs surpass potential mining rewards opens avenues for added revenue, fortifying miners’ bottom lines. Participating in DR programs allows miners to earn compensation for reducing energy usage during peak periods, effectively converting what could be unprofitable downtimes into opportunities for additional income. Such strategic decisions avoid high operational costs and place Bitcoin mining at the forefront of energy conservation and intelligent grid management while staying competitive.

As we approach the upcoming Bitcoin halving, miners face challenges and opportunities to sustain and potentially increase profitability. By leveraging advanced tools like Foreman, miners can navigate the complexities of reduced rewards through strategic firmware optimization, cost-effective operational adjustments, and active participation in Demand Response programs. These strategies ensure the efficiency and sustainability of mining operations and contribute to the broader energy ecosystem by providing much-needed flexibility and stability to the grid.

Mining hardware manufacturers continually push for greater processing power in new models. Bitmain, a key industry player, has led this endeavor since its initial Antminer, the Antminer S3, launched in July 2014. This began a series of powerful mining machines engineered to handle substantial hashes using the SHA-256 algorithm.

Bitmain’s Antminer series has played a pivotal role in the mining sector, elevating industry standards and expanding processing capabilities. These miners have significantly contributed to the transformation of Bitcoin mining from a niche pursuit into a thriving and industrialized field. In this article, we’ll explore the history, features, technical specifications, and the profound impact of Bitmain’s Antminer series on Bitcoin mining, highlighting how these machines continue to shape the industry landscape.

History and Development

Bitmain was founded in 2013 and quickly became one of the world’s largest manufacturers of Bitcoin mining hardware. Over the years, Bitmain has released a series of powerful and efficient mining machines, including the Antminer S1, S7, S9, T9, S15, and T15. These machines helped to make ASICs more accessible and profitable for miners.

In 2013, Bitmain released the Antminer S1. This landmark miner marked Bitmain’s entry into the market and laid the groundwork for the future. The Antminer S1, an ASIC device tailored for Bitcoin mining, represented a significant leap in efficiency and performance compared to early GPU mining rigs.

Antminer S1 first-generation:

Hash Rate: 180 GH/s

Release Date: 2013

Fast forward to 2020, Bitmain released the S19 series, which includes the S19, S19 Pro, and S19j Pro models. These machines were the first to use 7nm chips, reducing the energy cost required to mine Bitcoin. As a comparison, the S9 uses 16nm and was the most used ASIC on the market as recently as 2018.

Bitmain continues to raise the bar for the ASIC industry in 2024 with the release of the Antminer S21 series. This new lineup includes the Antminer S21 and the Antminer S21 Hydro, equipped with cutting-edge 5nm chips. The Antminer S21 boasts an impressive hashrate of 200Th/s while consuming 3550 watts of power, making it a formidable addition to Bitmain’s catalog. On the other hand, the Antminer S21 Hydro takes mining to the next level with a staggering hashrate of 335Th/s, albeit with a higher power consumption of 5360 watts. Notably, the S21 Hydro model introduces a hydro cooling system, allowing the machine to push more power through the chips.

Types, Series & Models

Antminer Types: Hydro & Air

The distinction between the air-cooled and hydro models of Bitmain’s Antminer series lies in their cooling methods and overall efficiency. Hydro models, like the Antminer S21 Hyd and S19 Hydro, stand out as the most powerful in terms of hashrate (TH) and offer slightly better energy efficiency measured in joules per terahash (J/TH) compared to their air-cooled counterparts. This enhanced efficiency can translate into lower operational costs for miners.

However, it’s crucial to note that hydro models come with additional considerations and costs. Operating hydro miners requires specialized infrastructure, such as cooling towers and dedicated systems, to effectively manage the water-based cooling system. Miners must consider the added costs and operational complexities of these infrastructure needs. When choosing between air-cooled and hydro models, environmental conditions, operational scale, and budget constraints become crucial.

On this performance chart, the dark blue areas represent Bitmain’s hydro-cooled Antminer models, while the light blue regions represent the air-cooled counterparts. Despite the dark blue areas indicating higher total hash rates for the hydro models, both hydro and air-cooled models exhibit similar energy efficiency when measured in joules per terahash (J/TH).

A deeper comparison can be made between the Hydro and Air-cooled between the years 2020 and 2024. On the chart below, the J/th efficiency is on the Y axis while the watts are the size of the circle, and the color is hydro or air-cooled. Hydro machines can produce more TH by pushing more watts through the chip. The S19XP is the first time an Antminer Hydro machine has meaningfully greater efficiency than the base, air-cooled model. Although the new S21 Hydro model isn’t out yet, the efficiency will be much higher than that of the air-cooled.

With all the comparisons between Hydro and Air-cooled, it is worth stating that each machine has its ups and downs compared to the specific location and use case. Some hydros may not be well suited for below-freezing temperatures, whereas air-cooled has an advantage in this climate. On the other hand, a facility in a more temperate location could take advantage of hydro machines that get more consistent cooling to the chips. In the mining world, every decision carries substantial financial implications, and inevitable missteps can result in significant losses, potentially rendering equipment irreparable and funds permanently lost.

Series (T & S)

The S series stands out for its exceptional hashing power and energy efficiency, leading the industry for a reason. They are machines that everyone knows as the flagship models.

On the other hand, the T series, exemplified by models like the Antminer T19 and T17, offers an alternative approach. While these models provide competitive hash rates, they are slightly less power-efficient than their S series counterparts. Miners who opt for the T series prioritize cost-effectiveness and may not be overly concerned with marginally higher power consumption. This choice can be especially advantageous in regions with favorable electricity rates, where the lower upfront cost of T series models can offset their relatively higher energy consumption.

In the world of energy production, the Nordic and Baltic regions stand out due to their wide range of generation methods. These regions are more than just picturesque, from wind turbines to solar panels juxtaposed against shimmering fjords and expansive forests. Yet, it’s not merely about harnessing energy but also managing and balancing it. Demand Response (DR) assumes significance in this equilibrium, particularly within the scope of Frequency Containment Reserves (FCR).

Why is Demand Response crucial in these areas, particularly regarding Frequency Containment Reserve? Beyond the immediate allure of renewable energy sources like wind, hydro, and solar lies the challenge of grid stability — an oscillation between surplus and deficit that requires meticulous control. As both the Nordic and Baltic regions aspire to increase their renewable energy generation, the utility of DR in harmonizing the grid’s supply and demand becomes undeniable.

Furthermore, Foreman has set a new industry standard by swiftly curtailing energy use in large-scale Bitcoin farms across the globe in just 5 seconds, contributing to an increased bottom line for our customers. To begin, let’s explore the intriguing realm of power dynamics. Within this investigation, we will discover the vital role that Bitcoin miners play as unsung champions in maintaining seamless, quick responses to the electrical grid.

How Does FCR Work?

In our previous articles, we have delved into the workings of demand response (DR). However, it is crucial to understand that while DR follows a similar concept worldwide, there are regional variations and nuances to consider. In the Nordic and Baltic regions, maintaining grid stability in the face of renewable energy fluctuations relies heavily on Frequency Containment Reserves (FCR).

FCR operates on a rapid-response mechanism, quickly counteracting unexpected shifts in power generation caused by factors like sudden wind changes, cloudy weather, or shifts in demand response during extremely cold winters. Demand Response (DR) plays a crucial role in this context. Instead of relying solely on traditional methods like adjusting power plant output, DR involves a network of energy consumers ready to adapt their energy usage on short notice. It’s a dynamic, two-way conversation facilitated by advanced technologies and communication systems between energy producers and consumers. Together, they help ensure the resilience of power systems in the Nordic, Baltic, and parts of Europe as they increasingly depend on renewable energy sources.

Locations and Markets for FCR

Nordpool

Nord Pool stands as Europe’s leading power market, playing a pivotal role in the electricity trading landscape of the Nordic and Baltic regions. Originating in 1991 as a collaborative initiative between Norway and Sweden, it has since expanded its reach, incorporating Denmark, Finland, Estonia, Latvia, Lithuania, and the UK. The Nordpool platform offers both day-ahead and intraday markets, which are essential components in determining the price of electricity based on supply and demand dynamics. Producers and consumers are provided transparency and predictability through these markets, helping them make informed decisions about electricity usage and production.

Each participating country’s Transmission System Operators (TSOs) play a role in this cooperative ecosystem. They relay vital information about available transmission capacities, ensuring the efficient flow of electricity across borders. To bridge this flow, Nord Pool acts as a trading platform and a crucial connector, harmonizing its member countries’ energy policies.

What are TSOs?

A Transmission System Operator (TSO) is responsible for reliable and efficient electricity transmission through high-voltage networks. Like ISOs in the USA, TSOs focus on infrastructure rather than generating or selling electricity, providing the link between generators and distribution networks, which deliver power to consumers. TSOs are critical in maintaining grid stability by ensuring safe frequency and voltage levels. If imbalances occur between supply and demand, TSOs take corrective actions like activating reserve power, conducting maintenance, and integrating renewables.

Each country usually has its own TSO because energy systems, regulations, and policies are closely tied to national interests. A dedicated TSO addresses a nation’s unique grid requirements and challenges, optimizing energy security and efficiency by considering local energy needs, resource availability, and grid conditions.

Listed Nordic and European TSOs

The Nordic countries are prominent players, with Sweden’s Svenska kraftnät, Norway’s Statnett, Finland’s Fingrid, and Denmark’s Energinet all employing the FCR mechanism. The Baltic states, comprising Estonia’s Elering, Latvia’s AST, and Lithuania’s Litgrid, also participate in this cooperative effort.

Europe also embraced FCR. Germany manages its FCR through multiple TSOs, including TenneT, 50Hertz, Amprion, and TransnetBW. The Netherlands aligns its practices via TenneT, Belgium, with Elia, Austria through APG, and Switzerland under the guidance of Swissgrid. France, under RTE, also recognizes the importance of FCR, although its engagement might slightly deviate from the standardized cooperation model observed in other countries.

Types of FCR

Frequency Containment Reserves (FCR) are integral components of the power system that ensure grid frequency remains within acceptable ranges. Different types of FCR are tailored to respond to various frequency deviations. Here’s a breakdown of the essential types:

Frequency Containment Reserve for Normal Operation (FCR-N):

This reserve manages smaller, regular deviations from the grid’s nominal frequency (typically around 50 Hz in many parts of the world). It aims to keep the frequency within a standard range, between 49.9 Hz and 50.1 Hz.

FCR-N is symmetrical, meaning it must increase (up-regulation) and decrease (down-regulation) power. Up-regulation could involve boosting power production or diminishing consumption, while down-regulation might mean cutting or elevating consumption.

Frequency Containment Reserve for Disturbances (FCR-D):

FCR-D is activated when more significant frequency deviations push the frequency outside the standard range. Its goal is to confine the frequency deviation to pre-defined thresholds, like 49.5 Hz or 50.5 Hz.

Unlike FCR-N, FCR-D is divided into distinct upregulation (FCR-D up) and downregulation (FCR-D down) products. Their activation is swift, often within seconds, to counteract significant frequency disturbances.

Both types of FCR are essential for maintaining a reliable and stable power grid, especially as more variable renewable energy sources, like wind and solar, are integrated. These renewable sources can introduce fluctuations in power generation, making FCR even more crucial in the modern energy landscape.

How Foreman Provides a Solution

Frequency Containment Reserves (FCR) are vital for maintaining the stability of power grids, especially with the increasing integration of renewable energy sources. Foreman’s advanced management system streamlines this process, allowing large mining sites to adjust energy use instantly, proving invaluable in today’s energy landscape.

The variability of renewables heightens the need for frequency regulation. In context, solutions like FCR, enhanced by platforms like Foreman, play a crucial role in bolstering stability for local networks during the transition to renewable energy. Enrolling in FCR programs requires both technical prowess and substantial upfront investments. Due to the high barriers to entry, smaller players are often sidelined. However, Foreman bridges this gap by equipping users with the needed tools. Foreman enhances grid stability and allows participants to tap into potentially massive increased revenue and bottom line.

As the landscape of the Bitcoin industry evolves, miners are embracing a transformative shift that could reshape their role in the technology ecosystem. The traditional scope of Bitcoin miners is being broadened to include the colocation of high-performance computing (HPC) applications, particularly in artificial intelligence (AI).

This pivot is primarily driven by miners’ recognition of the versatility of their facilities and the potential to tap into new revenue streams in a rapidly changing market. The transition holds particular significance in the wake of the move of Ethereum’s Proof of Work (PoW) to Proof of Stake (PoS), which has resulted in a surplus of Graphics Processing Units (GPU) that can be harnessed for High-Performance Computing (HPC) AI applications, showcasing the industry’s proactive approach to maximizing resource utilization and stability. As miners repurpose their powerful GPUs for AI tasks, an emerging challenge lies in efficient compute load scheduling to optimize Bitcoin mining and AI operations.

How HPC AI Compute Works

As miners strategically purchase or repurpose their Graphics Processing Units (GPUs) for AI tasks, the challenge of efficient computational load scheduling takes center stage in the world of High-Performance Computing (HPC) environments integrating Artificial Intelligence. This task involves optimizing resource utilization, minimizing execution time, and system compute load. Effective scheduling ensures the HPC cluster’s computational resources are utilized efficiently.

HPC AI compute load scheduling begins with a thorough workload analysis, where AI tasks’ computational requirements, data dependencies, and priorities are examined to allocate appropriate resources. Various scheduling policies are then employed to manage resource allocation. These policies include First-Come, First-Served (FCFS), Fair-Share Scheduling, Priority Scheduling, and Backfilling. These policies were designed to optimize task execution order and resource assignment.

Parallelism and compute resource balancing techniques are pivotal in distributing tasks across available resources. Since many AI workloads can be executed in parallel, these methods ensure even resource utilization, avoiding situations where some resources are idle while others are overloaded. The scheduler considers resource availability, including CPU, GPU, memory, and network bandwidth, and constraints like software compatibility and user access policies. The dynamic nature of HPC AI environments necessitates adaptability, with schedulers adjusting to changing conditions such as newly available resources or increased compute demand.

AI-enhanced scheduling might involve prioritizing tasks that require more resources or are highly important, ensuring critical operations are executed promptly. The goal is to maximize resource usage, reduce execution time, and facilitate efficient AI model development and deployment.

Colocating HPC AI and Bitcoin Machines

Bitcoin miners, colocated with powerful GPUs (Graphics Processing Units), are capitalizing on the adaptability of their technology. By repurposing GPU hardware for AI tasks, such as complex scientific simulations, rendering, and machine learning, miners are venturing beyond the confines of Bitcoin mining in a single facility. This approach aligns seamlessly with the overarching trend of leveraging high-performance computing resources for AI applications, reflecting a broader synergy between these two domains.

The bitcoin mining company Applied Digital showcases one compelling example of this trend. The company has recently sealed a substantial AI hosting deal. Under this agreement, Applied Digital will use its powered data center capabilities to host AI applications.  This confluence of cryptocurrency mining and AI technologies introduces new revenue avenues and optimizes resource utilization in an ever-evolving technological landscape while employing diversification of revenue streams.

The shift also reflects the agility and adaptability of miners as they navigate changing market dynamics. As the boundaries between Bitcoin mining and cutting-edge technologies blur, miners are positioning themselves at the forefront of innovation, propelling the industry into uncharted territories that promise financial diversification and technological advancement.

Diversification in a Volatile Industry

Integrating HPC for AI applications represents a transformative strategy for Bitcoin miners to bring newfound stability to an industry notorious for its volatility. With substantial power resources, miners leverage their significant computational capabilities to engage in sophisticated AI endeavors. This shift allows them to diversify their operations and serves as a strategic hedge against the unpredictable nature of Bitcoin mining.

Amidst Bitcoin’s current bear market, major mining facilities can strategically leverage the rising demand for high-performance computing (HPC) AI. This diversification helps stabilize revenues while Bitcoin mining regains profitability. The approach gains significance ahead of the 2024 halving, as miners seek to gauge the uncertain ROI before investing in new machines, given the impending reduction in revenue due to halving effects.

AI’s trajectory from a once-dismissed buzzword to an integral part of our technological fabric has been remarkable. What once seemed like a distant promise is now a tangible reality, with AI firmly establishing its presence across various industries. Companies recognize its potential and harness its capabilities for seamless integration, propelling AI into the mainstream. From self-driving cars to personalized content recommendations, AI has embedded itself into our daily lives, enhancing convenience and efficiency. As AI continues to weave into the fabric of our existence, it’s evident that its impact is not just a passing trend but a transformative force that’s here to stay.

As Bitcoin miners venture beyond their traditional role into AI HPC, they are not only adapting to the evolving landscape but also laying the groundwork for a more diversified future. Repurposing powerful GPUs for AI tasks showcases the industry’s resilience and ability to harness its technological prowess to explore new avenues. This strategic shift could stabilize a volatile sector and position miners at the forefront of cutting-edge technological developments. With the fusion of Bitcoin mining and AI, miners are embracing a multifaceted approach that could shape the future of technology, innovation, and economic sustainability.

The fee market in Bitcoin is a testament to the decentralized and trustless nature of the network. Rather than relying on a centralized authority to determine transaction fees, users compete with one another to have their transactions included in the limited block space available. This market-driven approach ensures that transaction processing is efficient and fair while incentivizing miners.

In this article, we will delve into the intricacies of the Bitcoin fee market, exploring its evolution, dynamics, and the factors that influence fee levels. Fees can jump instantly, driving revenue for miners, sometimes doubling in a few days. Here, we will examine the concept of inscriptions and how the fee market has evolved, considering technological advancements and the ever-changing landscape of Bitcoin.

How the Mempool and Fees Work

The mempool is a temporary storage area where unconfirmed transactions wait to be included in a block. Miners select transactions from the mempool based on transaction fees and size. Transactions with higher fees are typically prioritized for faster confirmation. Once a transaction is selected for inclusion in a block, it is removed from the mempool and considered confirmed.

Technically, everyone in the Bitcoin network maintains their node’s mempool (if they run a node). When a transaction is initiated, it is gossiped to peers until it reaches every node in the network. This method ensures that all participants have heard of the transaction and miners can see it in the mempool.

History of the Fee Market

The scarcity of block size and time in Bitcoin creates a competitive environment where transactions vie for limited block space, with one block being confirmed every ten minutes on average (600 seconds). As transaction demand increases, the fee market intensifies. Users seeking faster confirmation may attach higher fees to their transactions called Replace by Fee (RBF), or new transactions raise fee rates to incentivize miners to prioritize them. This heightened competition in the fee market reflects the increased demand for scarce block space. The interaction between transaction demand, limited block space, and the fee market showcases scarcity’s essential role in shaping the transaction ecosystem within Bitcoin.

Limited block space, time, and funds contribute to a fluctuating free market of transactions. The chart below represents ‘block time’ (a scarce resource), wherein each block approximates 600 seconds, or every ten minutes, due to Bitcoin’s programmatic nature. The yellow line signifies the ‘Block Size.’ During the peak of the bull market in 2017, it reached its maximum size. With the implementation of Segwit, the block size remained constant. However, additional transaction data can now be stored in the ‘witness,’ leading to block sizes that exceed 1MB. We’ll delve further into this topic later in the article. Scarce block space, and scarce time, with scarce money, create a free market of transactions that can fluctuate equally. The below chart illustrates block time (scarce), where each block hits around 600 seconds or every ten minutes due to the programmatic nature of Bitcoin. The yellow line is Block Size, which at the height of the bull market in 2017, was hitting its peak size. Segwit was implemented, and the block size stayed the same, but now other transaction data can be stored in the “witness,” which is why the block size exceeds 1MB. We’ll cover this further in the article.

The block size limit issue has sparked considerable debate within the Bitcoin community. Initially established at 1 MB, disputes over block size and Bitcoin scalability arose as early as 2014. This led to a hard fork in 2017, resulting in Bitcoin Cash, during a period known as “The Blocksize War”.
Segregated Witness (SegWit) was introduced as a backward-compatible upgrade to address these concerns. SegWit separates the transaction signature data, or “witness data”, from the transactions themselves. This effectively increases the blocks’ capacity by reducing each transaction’s size. The optimization allows more transactions to fit within a block, which helps to alleviate network congestion and lower transaction fees.

SegWit doesn’t just enhance scalability; it also offers additional benefits such as increased security and the potential for implementing new features. One such feature is a “Layer 2” solution known as “The Lightning Network.” Since SegWit was activated in 2017, its adoption has been steadily increasing, effectively addressing the block size limit issue and enhancing the efficiency of the Bitcoin network.

The record for the largest transaction in Bitcoin history was set in February 2023, with a block and witness data totaling approximately 3.96MB.

Scaling with Lightning

Implementing Segregated Witness (SegWit) and the subsequent introduction of the Lightning Network has initiated a notable shift in transaction activity within the Bitcoin ecosystem. The Lightning Network offers significant advantages like lower fees and faster transaction processing times. As a result, smaller transactions that may not be economically viable on the base layer have found a suitable home on the Lightning Network. This transition to layer two likely contributed to a reduction in the number of transactions on the base layer, as depicted in the graph below. It illustrates a decline around 2019, reflecting the increasing adoption of the Lightning Network, followed by a substantial spike in Bitcoin within Lightning Network channels in 2021. This pattern aligns with the hypothesis that the Lightning Network has provided an alternative and more efficient medium for smaller transactions, relieving some of the demand from the base layer of Bitcoin. The final spike (2023) in transactions can be attributed to BRC-20 tokens and inscriptions, which we’ll cover in the next section.

Inscriptions Have Changed the Fee Market

Miners do not need to understand technically what inscriptions and ordinals are, but knowing why they exist and where they come from gives insight into how they affect the fee market.

What are Inscriptions and Ordinals?

Within Bitcoin, ordinals serve as unique identifiers attached to each transaction. They verify digital assets’ authenticity, ownership, and distinctiveness, including inscriptions like Non-Fungible Tokens (NFTs) and BRC20 tokens (the Bitcoin equivalent of ERC-20 tokens). These ordinals enable the tracking and validating the transfer and ownership of digital assets on the Bitcoin blockchain. By leveraging the security and immutability of the Bitcoin network, inscriptions ensure the integrity of transactions and the assets associated with them. They enable tokenization, transfer, and verification of digital assets within the decentralized framework of Bitcoin.

Inscriptions and the Fee Market

In 2023, inscriptions increased fees and congestion in the Bitcoin mempool. Users attached higher fees to their transactions to reach confirmations sooner, leading to intensified competition for limited block space and longer confirmation times. This resulted in an overall increase in fees and a more congested mempool. The increased fee market started partially in Feb 2023 and significantly increased in late April, when fees spiked due to the emergence of BRC-20 meme tokens created through inscriptions within Bitcoin blocks.

They are literal meme tokens. Examples include “pepe”, “moon” and “meme”.

Inscriptions can be categorized into two major types: NFT inscriptions and BRC20 inscriptions. NFT inscriptions (Blue in the chart below) are associated with Non-Fungible Tokens and typically require more block space due to the complexity and size of NFT transactions.

On the other hand, BRC20 inscriptions are linked to BRC20 tokens, which generally have smaller transaction sizes and consume less block space. This distinction in transaction size between NFT and BRC20 inscriptions highlights the varying space requirements and impact on the mempool congestion for different tokens within the Bitcoin network.

The two significant types of ordinal transactions can be categorized as “Boulders” (NFTs) and “Grains of Sand” (BRC-20). NFT transactions, represented by the Boulders, are larger transactions that put a significant load on the network but still leave room for regular transactions. Despite the relatively lower frequency of NFT transactions, they still compete for fees, contributing to the overall fee market dynamics. Alternatively, the “Grains of Sand” represent smaller transactions, often associated with BRC20 tokens. These transactions can generate a significant volume simultaneously, effectively “clogging” the mempool and driving up fees. The influx of BRC-20 transactions led to a substantial spike in transaction fees. The combination of both types of transactions, characterized by their different sizes and transaction volumes, increased congestion and significantly higher fees on the Bitcoin network.

The introduction of BRC-20 tokens significantly increased the number of transactions waiting in the Bitcoin mempool. This influx of transactions put substantial pressure on the network, driving prices upwards and causing a fee surge. The increased competition for block space resulted in users increasing their fees to ensure their transactions were prioritized for inclusion in a block. This fee spike persisted for approximately ten days in May 2023, during which users had to adjust to the heightened fee market conditions, and miners were getting paid more through fees than the actual block reward. However, as the initial surge of BRC-20 transactions subsided, the mempool congestion gradually diminished, leading to a fee decline. The market eventually normalized, bringing fees back to more manageable levels.

More Transactions per Second

Due to the small transaction sizes of BRC20 tokens, the number of Bitcoin transactions surged to over 6 per second. This increase in transaction volume can be observed by examining the Median Transaction Size historically. The influx of BRC20 transactions notably impacted the overall transaction activity and the mempool, resulting in heightened congestion. However, as the surge in ordinal transactions subsides, the transaction activity and mempool gradually return to a calmer state. In the future, the transaction ecosystem is expected to find an equilibrium as users and the network adapt to the increased utilization of BRC20 tokens and optimize fee market dynamics accordingly.

The Future of the Fee Market and Inscriptions

The creation and minting of BRC20 tokens and NFTs currently appear focused on generating these assets, with a low transfer rate observed in transactional history. It suggests that creators are positioning themselves for the next bull run, intending to transfer these assets to other buyers during that period.

The total fees associated with inscriptions have reached an impressive $55 million. This significant expenditure without an immediate return on investment diverges from the historical goal of seeking profits in altcoins and NFTs. In contrast, Bitcoin has traditionally been viewed more as a store of value than a speculative tool.

Looking ahead to the coming bull market, there will likely be an influx of new participants seeking to take advantage of meme token types and NFTs, driven by the desire to make substantial gains through gambling and speculation. This anticipation may increase creation and transfer activity, potentially driving up the fee market. With the vitality of a new bull market, fees could reach unprecedented heights never seen before as these transaction types are brand new, and we need to understand how they will impact the fee market during high transaction volumes.

History of Fee Market Exhuberance

Historically, a notable fee surge within the Bitcoin network has occurred during each bull cycle. As the market experiences heightened activity and increased demand for transactions, fees gradually accumulate, and the mempool grows. This growth continues until reaching a peak of exuberance. It is often observed that this peak in fees coincides with the market’s top during the bull cycle, although it may not be an exact timing indicator. During this period, more users are eager to send transactions, and the pricing of each transaction is predominantly valued in USD rather than BTC. This psychological shift is significant since Bitcoin is priced in USD, influencing users to think and spend in terms of USD pricing. This trend is consistently observed throughout each bull market, with the peak of weekly average fees typically reaching around $50 as an example of this pricing dynamic.

Predicting the exact impact of inscriptions on the fee market during the upcoming bull run is impossible. Several factors contribute to the evolving fee dynamics, including adopting layer two solutions that reduce the reliance on layer one transactions.

Additionally, the influx of new participants attracted by the rebranding of NFTs and altcoins on the Bitcoin blockchain adds an element of uncertainty to the fee market. The market’s behavior could follow different scenarios, such as increased congestion with transactions still being processed or a similar pattern of transaction spikes as observed in previous cycles. Observing how the market evolves and whether it experiences more extended periods of whole blocks with transactions being processed or follows a familiar pattern of transaction surges will be interesting. The future direction of the fee market remains uncertain, but what is known is the resilience of the Bitcoin network and eb and flow in fees.

Only time will reveal the impact of inscriptions on the fee market during the next bull run. This helps miners understand the dynamics, potential transaction charges, fees, and mempool. This understanding should help users navigate the fee market more effectively. Observing the interplay between inscriptions and fees will provide valuable insights as the market evolves. Time will ultimately unveil the full implications of inscriptions.

Shutting down power throughout a mining facility may seem routine, but the consequences of inaccurately or manually flipping breakers can be far-reaching and potentially cause permanent damage to ASICs. This article will explore other reasons why programmatically utilizing strike price-based curtailments can be beneficial. We’ll also focus on a case study of an immersion facility that decided to initiate a power shutdown to participate in a demand response program.

Even when carried out with good intentions, manual power shutdowns (via breakers) can unleash a series of catastrophic events that disrupt operations, jeopardize equipment, and lead to substantial financial losses. The case study discussed here is a tale of caution, highlighting the importance of understanding the potential consequences of not implementing a comprehensive program like Foreman to mitigate risks through automated curtailment.

Programmatic Consistency in a Chaotic Market

Consistency in chaos is crucial to programmatic curtailment processes. Real-time index pricing volatility, seasonal price increases, quarterly changes in time-of-day pricing, and minute-by-minute variable factors underscore the need for a programmatic strategy in the wild west of real-time energy markets like ERCOT. By leveraging automation and programmatically curtailing, mining facilities can respond swiftly to pricing fluctuations, optimize energy usage, and maintain operational efficiency in an ever-changing market environment.

Real-Time Index Pricing Volatility

Index volatility poses significant challenges for manual curtailment processes. Many resources are required to manage curtailment based on real-time pricing effectively. Working curtailment this way includes dedicating multiple individuals to constantly monitor ERCOT real-time pricing for day and night shifts, covering all daytime hours. Such a manual approach would demand significant time, effort, and financial investment, as personnel are due full-time or be paid at least around the clock to fulfill this monitoring role. By contrast, automating curtailment processes eliminates the need for constant human oversight, reduces staffing costs, and allows for efficient and cost-effective curtailment management based on real-time index pricing volatility.

The graph below illustrates the importance of programmatically automated curtailment during unprofitable periods. Each dot represents the average hourly price in ERCOT, with yellow indicating unprofitable times and blue representing profitable ones. Foreman’s software-based curtailment enables efficient energy usage and maximizes profitability without needing constant manual intervention.

How Summer Heat Affects Energy Prices

The ERCOT energy price market is significantly impacted by summer heat, with the hottest days often leading to increased electricity prices. Despite the substantial contribution of solar energy production, more generation capacity is still needed to offset the high demand during scorching summer days. As a result, energy prices soar due to the strain on the grid. These spikes in pricing highlight the need for expanded energy production capacity to meet the surging demand during peak periods. Additionally, implementing effective curtailment strategies becomes crucial, particularly during low-demand months, to ensure a balanced energy supply and manage pricing fluctuations from a macro and statewide perspective.

Implementing Foreman enables automated curtailment, reducing stress on the grid and streamlining mining operations. By optimizing energy consumption based on grid conditions, Foreman contributes to grid stability while promoting energy efficiency and cost savings on a company-to-company level.

The Purpose of Programmatic Curtailment

This case study highlights the necessity of integrating Foreman into mining operations to manage curtailment. Foreman integration is critical in mining facility operations by providing automated software and firmware capabilities that contribute to seamless and uninterrupted workflows. One of Foreman’s key features is automated power ramping, gradually reducing power consumption through enabled software and firmware. This controlled approach ensures a smooth transition, avoiding disruptions and potential issues associated with sudden power fluctuations.

This article explores the scenario of an immersion facility that opted to participate in a demand response program by “breaker flipping” or shutting down power facility-wide. It delves into their challenges, the extensive damage caused, and the efforts required to restore normal operations. By analyzing this case study, we demonstrate the need to implement robust management systems, such as Foreman, to ensure the smooth execution of automated curtailment and minimize the associated risks.

Key Takeaways from Case Study:

• Increased Risk of Equipment Damage.
• Missed Revenue for Load Optimization.
• Exacerbated Intervention and Response.
• Manual, not automated curtailment.

Immersion Case Study

Recently, a mining facility faced a series of damaging events when the CSP (Centralized Service Provider) abruptly interrupted their service without a safe power-down of the machinery. At the time, the facility had yet to incorporate Foreman. Instead of a controlled shutdown, this unexpected power cut led to severe complications. The repercussions of this situation underscore the importance of robust tools like Foreman. These systems manage service interruptions in a way that prevents abrupt shutdowns.

Curtailment and Immersion Shutdown:

Due to the circumstances above, the CSP decided to curtail the mining facility’s recloser. As a result, the mining equipment, including the immersion cooling systems, was abruptly shut off. Immersion cooling is a method that uses a dielectric liquid to cool mining rigs, enhancing their efficiency. With the power cut off, the cooling systems ceased functioning, which had a cascading effect on the entire facility.

Air Bubbles and Miner Failures:

When the site was reenergized after the curtailment, the mining facility faced a critical issue—air bubbles had become trapped in the cooling tubes of the immersion system. These air bubbles disrupted the flow of the dielectric liquid, causing the mining rigs to overheat. The issue went unnoticed without Foreman’s proper monitoring and control, exacerbating the situation.

In some cases, temp gauges can short out from the massive surge of electricity, prolonging the issue and possibly damaging machines.

Secondary Equipment Failures

The consequences extended beyond the primary mining rigs. The sudden power surge during the restoration process also impacted expensive secondary equipment. Computers, servers, and other essential components experienced failures and required hard reboots. These critical system failures prolonged the downtime and introduced the risk of data loss and additional damage to the facility’s infrastructure.

Facility-Wide Disruption:

The facility was left in disarray for an extended period with no on-site personnel available to promptly diagnose and address the issues. Miner failures, secondary equipment malfunctions, and power surges caused significant disruptions, rendering the facility non-operational for several hours. The financial losses incurred during this time were substantial, and the impact on production and operational efficiency was severe.

The case study above serves as a stark reminder of the potential consequences that can arise when mining facilities operate without integrating a comprehensive management system like Foreman. The events following the curtailment, from miner failures to secondary equipment malfunctions, underscore the critical need for continuous monitoring, early detection of issues, and remote management capabilities. By integrating Foreman into their operations, mining facilities can proactively safeguard against such incidents, ensure operational continuity, and minimize financial losses caused by unforeseen events.

It also offers a user-friendly interface, easy setup, and detailed instructions for beginners and advanced users. The pool is strongly committed to customer support and assists miners with issues or questions.

Payout Methods & Fees

Antpool uses two main payout methods to distribute Bitcoin rewards to its miners: Full Pay Per Share (FPPS) and Pay Per Last N Shares (PPLNS). FPPS is a popular payout method that guarantees a fixed payout for each share submitted by the miner, regardless of whether a block is found. This means that the pool takes on the risk of paying out for each share and charges a higher fee for this payout method to cover the additional risk. FPPS is ideal for miners who want a more stable and predictable income, as they receive a payment for each share submitted, regardless of the number of blocks the pool found.

Pay Per Last N Shares (PPLNS), on the other hand, pays out based on the number of shares contributed by the miner over a specific period, usually the last N shares. Payouts are only distributed when the pool finds a block, and the rewards are distributed proportionately among the miners who contributed to the pool’s mining effort during that period. PPLNS is a more complex payout method that considers the amount of work contributed by each miner over a certain period. PPLNS payouts may fluctuate more than FPPS payouts but can also be more lucrative when the pool finds many blocks.

Fees

Antpool charges a fee for using its mining pool services, which is deducted from miners’ Bitcoin rewards. The fee structure of Antpool varies depending on the payout method used:

• Full Pay Per Share (FPPS): Antpool charges a flat fee of 2.5% for FPPS payouts.
• Pay Per Last N Shares (PPLNS): Antpool charges a 1.5% fee for PPLNS payouts.

It’s important to note that Antpool does have a minimum payout threshold of 0.001 BTC for both FPPS and PPLNS payout methods.

As the world of Bitcoin mining continues to evolve, miners play a crucial role in ensuring the security of the decentralized network by validating new transactions and adding them to the blockchain. By pooling their resources, miners can improve their chances of successfully mining blocks and earning rewards.

This article will comprehensively cover mining pools, including their importance and how they work. We aim to equip you with the knowledge necessary to make informed decisions about participating in the dynamic landscape of Bitcoin mining.

Why Do We Need Pools?

Before the existence of mining pools, miners engaged in solo mining, working independently to find and validate new blocks on the blockchain. They would receive the entire block reward if their hash were successful in mining a block. However, as the Bitcoin network grew and mining difficulty increased, solo mining became less attractive due to the high variability in block discovery time and the increasing computational power required.

Mining pools emerged as a solution, allowing miners to work together and share rewards based on individual contributions. By pooling their resources, miners in a mining pool collectively increase their chances of finding a valid block, leading to more frequent and consistent payouts than solo mining.

How Do Mining Pools Work?

There are two main participants in pool logistics: miners and pool operators. Miners contribute their computational resources (hash power) to the pool and work on mining tasks assigned by the pool, submitting shares as proof of their contribution. They earn rewards based on the number of shares offered, reflecting their contribution to the mining effort.

On the other hand, the pool operator manages and maintains the pool’s infrastructure. Most importantly, operators run the pool server, which distributes mining tasks and tracks submitted shares. The operator also controls the pool’s reward distribution and shares difficulty adjustments. In return for providing these services, the pool operator typically charges a fee for providing these pool services. Miners and the pool operator collaborate to increase the pool’s overall hash power, allowing the pool to compete more effectively for block rewards. This collaboration benefits miners by providing a more consistent income stream while the pool operator earns revenue from the fees charged to pool members.

Pool Servers

The pool server is a crucial component in a mining pool, responsible for managing communication and coordinating miners’ efforts. It handles workload distribution by breaking down the mining process into smaller tasks or shares that assign miners based on their hash power. Delegating work according to contributed hashrate ensures that miners are paid appropriately for the amount of hashrate they contribute to the overall pool effort.

As miners work on their assigned shares and submit them back to the pool server, the server tracks the total shares submitted by each miner. When the pool successfully mines a new block, the block reward and transaction fees are distributed among miners based on the proportion of shares they submitted during the mining round. Some payout structures differ and will be covered in the reward section. This workload distribution enables miners of all sizes to work together efficiently, improving their chances of successfully mining blocks and earning rewards for the pool.

Bitcoin Pool Protocol Evolution

Getwork

The Getwork protocol is an early method used in Bitcoin mining for miners to request work from mining pool servers. Miners would request work from the protocol, receive a block template, and then try to find a valid hash for the block. They would send the solution back to the server and receive Bitcoin if successful. The Getwork protocol was the first mining protocol used in Bitcoin, introduced in 2010 by Gavin Andresen.

However, Getwork had some limitations and needed to keep up with mining hardware as ASICs became more efficient. When Getwork struggled, miners began to look for a better solution.

Stratum V1

Stratum V1 is a widely used mining protocol designed to improve communication efficiency between miners and mining pool servers. It was designed to address the limitations of the earlier Getwork protocol, offering better scalability, reduced network overhead, and support for advanced mining features.

The Stratum V1 protocol establishes a persistent connection between the miner and the mining pool server. This connection enables real-time communication and reduces the need for constant polling, a significant limitation of the Getwork protocol. Instead of sending entire block templates, Stratum V1 updates the miner when certain parts of the block template change, such as new transactions or changes in block height. This approach significantly improves efficiency and reduces bandwidth usage and latency.

Stratum V1 also introduced the concept of share difficulty, allowing miners to submit shares lower than the network’s target difficulty. This enables mining pools to track individual miners’ contributions better and distribute rewards more fairly.

Stratum V2

Stratum V2 is an improved mining protocol offering better efficiency, security, and flexibility than Stratum V1. It uses a binary-based communication protocol, reducing bandwidth usage and latency and enabling even faster communication between miners and mining pool servers.

This improvement protocol enhances decentralization by allowing miners to create block templates, improving the network’s security. Another key improvement is the introduction of compact blocks, which provide a summarized version of block data.

Implementing Stratum V2 in the Bitcoin mining landscape starts with ensuring that its creators and the community fully develop, test, and refine the protocol. Providing comprehensive documentation, guides, and resources will help mining pool operators, software developers, and firmware developers understand and implement Stratum V2. Braiins was the first to implement Sv2 in half, but not fully. Encouraging developers to update existing mining software and firmware or create new alternatives that support Stratum V2 is crucial. Mining pool operators should also update their server software to ensure compatibility and seamless communication with miners using the updated protocol.

To ensure a smooth transition, it’s essential to have backward compatibility with Stratum V1 for miners who have yet to upgrade to Stratum V2. Providing information and support to miners on the benefits of Stratum V2 and guiding them through updating their mining software and firmware is necessary. Continuously monitoring the performance and adoption of Stratum V2 while addressing any issues or concerns that arise during the transition process will contribute to the protocol’s success. Fostering an open and collaborative environment will enable the mining community to contribute to the development, adoption, and improvement of Stratum V2, ultimately establishing it as the industry standard. Additionally, there is an opportunity within the Fedimint protocol to further advance Stratum V2 in what is called Fedipool and an additional pool type on top of V2.

“Rather than a single pool operator constructing blocks and choosing which transactions to include, each Guardian can construct their own blocks, reducing censorship risk. Additional miners can join the pool in the future to take advantage of the above, but rather than be a Guardian, they choose which Guardian they want to construct their blocks.” – Odell

Choosing A Mining Pool

Five Factors To Consider

To make the most of your mining, it’s crucial to consider several factors when choosing a mining pool. These include the pool’s reputation, fees, reward distribution method, size and hashrate, and location and server stability.

1. Reputation: Choose a pool with a good reputation in the mining community based on feedback and reviews from other miners.
2. Pool fees: Compare pool fees and choose a pool with competitive fees that align with your preferences.
3. Reward distribution method: Choose a pool with a reward distribution method that aligns with your risk tolerance and preferences.
4. Pool size and hashrate: Consider the pool’s size and hashrate, choosing one that aligns with your desired balance between payout frequency and size.
5. Location and server stability: Choose a pool with servers closer to your location that is reliable and stable.

Reward Distribution Methods

Miner reward distribution methods are how Bitcoin mining pools allocate block rewards and transaction fees among their participating miners. These methods compensate miners fairly for their contributions to the pool’s combined hash power. Some standard miner reward distribution methods include:

Transparent Index of Distinct Extended Shares (TIDES): TIDES is a forward-thinking Bitcoin mining reward system created by Oceans Pool that offers direct payouts to miners for valid proofs (proof of work) once a block is mined. This approach mirrors the FPPS model in providing payments post-block discovery but diverges by forgoing a central wallet for distributing funds. Instead, TIDES ensures that the block reward, including transaction fees, is sent directly to miners’ addresses, enhancing transparency and minimizing trust issues associated with intermediary handling. The system is designed to be fully auditable. It does not require the mining pool to act as a custodian, thereby streamlining the reward process and ensuring a transparent and equitable distribution of the mining rewards.

Pay Per Share (PPS): In PPS, miners receive a fixed payment for each valid share they submit, regardless of whether the pool mines a block. This method provides a stable income for miners but often comes with higher pool fees, as the pool operator takes on the risk of variance.

Full Pay-Per-Share (FPPS): Similar to PPS, this is a reward system used by some mining pools that offer a fixed payout for each valid share miners contribute. This payout usually combines the block reward and transaction fees and provides a predictable payout for miners.

Pay Per Last N Shares (PPLNS): PPLNS considers a miner’s contribution over a set number of shares (N) when a block is found rather than just the shares submitted during the current mining round. This method rewards loyal pool participants and discourages pool hopping. PPLNS can lead to variance in miner rewards, as miners are only paid when a block is found, but usually, this schedule has lower pool fees.

Pay Per Share Plus (PPS+): PPS+ combines elements of PPS and PROP, offering both fixed payments for each share and a separate proportional reward based on the number of shares submitted when a block is found. This method can provide stable earnings while incentivizing miners to contribute consistently.

Different Bitcoin mining pools use different reward distribution methods, depending on the pool operator’s preferences and the mining community.

Pools and Miners Participating in Demand Response

Demand Response is a concept in which miners adjust their electricity consumption in response to grid supply and demand changes. For example, this can be done by temporarily reducing mining activities during peak demand periods or increasing mining during periods of low demand and lower electricity prices. To participate in Demand Response, miners need a flexible reward distribution method that doesn’t penalize them for temporary reductions in hash power.

The Pay Per Share (PPS) method is likely the most suitable for miners participating in Demand Response. In the PPS method, miners receive a fixed payment for each valid share they submit, regardless of whether the pool mines a block. This method provides a stable income for miners and doesn’t penalize them for reducing their hash power during peak demand periods, as they get paid for each share they submit.

By contrast, other reward distribution methods, such as Proportional (PROP) and Pay Per Last N Shares (PPLNS), may be less suitable for DR participants, as they consider a miner’s contributions over a more extended period or during the entire mining round. Miners participating in Demand Response might miss out on rewards during peak demand periods, as they would submit fewer shares during those times.

ASICs

• Understand ROI
• Cost of ASIC vs. hashrate and J/TH
• Historical revenue per kWh

Choosing the right ASIC miner is critical to the success of your Bitcoin mining operation. When selecting an ASIC miner, you should consider several factors, such as the hash rate, power consumption, purchase timing, ROI, and cost.

Cost is another essential factor to consider, as ASIC miners can be expensive, and you’ll need to factor in the ROI (Return on Investment) and other associated costs to determine the profitability of your mining operation. Some miners say when purchasing equipment, there should be an ROI of around 12 months for each machine.

One of the most significant drawbacks is the high cost of buying new miners. New machines can be expensive, and you may need to invest substantial capital to purchase the necessary equipment to start your mining operation. Furthermore, purchasing new machines may also come with the risk of encountering technical issues or defects, resulting in downtime and lost profits.

As new machines hit the market, the efficiency or J/TH of the average machine will move up and start to price out older machines. The other factor to consider is the price of Bitcoin and the bull run. Bitcoin runs in cycles, so purchasing when there is blood in the streets is a good idea, although it can be risky to do so right before the halving when your revenue will get cut in half.

During bull runs, most revenue is produced because the difficulty has not caught up to the price increase, and miners lag bull runs. The demand for machines that produce revenue increases as revenue increases, and the machines’ price follows. It is good to plan out in 4-year increments as the Bitcoin halving plays a big role in the price and price of machines.

ASICs & Manufacturers

Below is a list of popular Bitcoin ASIC miners from various manufacturers, showcasing their energy efficiency measured in joules per terahash (J/TH). These values are essential when comparing the performance and cost-effectiveness of different mining hardware.

Automatic transfer switches monitor the primary power source and automatically switch to backup power when the main supply is interrupted or unstable. Transfer switches ensure a continuous power supply to the mining equipment. High-quality electrical cabling, conduits, and connectors are necessary for safe and efficient power transmission throughout the facility. Choosing suitable cable types, sizes, and installation methods is crucial for optimal performance and reducing potential hazards.

A Power Distribution Unit (PDU) differs from the PSUs described above. PDUs distribute power to multiple devices or components, such as ASIC miners, servers, switches, and other networking equipment. When choosing a PDU, it’s essential to consider its power rating and ability to prevent the overloading of electrical circuits. Overloading can occur when a PDU supplies more power than the electrical circuit can handle, which can cause damage to the devices and increase the risk of electrical hazards. Choosing a PDU with circuit breakers that can automatically shut off the power when an overload is detected is essential to prevent overloading.

Additionally, some PDUs have remote monitoring and control features, which allow administrators to monitor power usage, track power consumption, and control power distribution remotely. These features can be advantageous in large mining farms where multiple PDUs distribute power to numerous devices. If you want a deeper dive into PDUs, check out our article explaining everything you need to know.

Cooling System, Filtration, and Airflow

• Air conditioning units
• Fans
• Liquid cooling systems
• Temperature monitors
• Mechanical filters (such as air filters, screens, or meshes)
• Other filtration methods (such as electrostatic, UV-C, activated carbon, or HEPA)

The cooling system is a crucial component of a Bitcoin mining farm’s infrastructure as it helps regulate the temperature of the mining hardware, prevents overheating, and ensures optimal performance. ASIC miners used for Bitcoin mining generate a significant amount of heat during operation, and if the temperature is not regulated, it can damage the hardware and decrease mining efficiency.

The system typically includes a combination of air conditioning, ventilation, and fans that work together to maintain a stable temperature within the mining farm. The air conditioning system cools the ambient temperature within the room, while the ventilation system helps circulate the cool air and remove hot air from the room. Fans placed near the mining equipment blow cool air directly onto the ASIC miners to help regulate their temperature.

In addition to traditional cooling methods, liquid cooling systems are becoming more popular in Bitcoin mining farms. Liquid cooling involves circulating liquid coolant through the ASIC miners to dissipate heat more efficiently. Liquid cooling can help achieve a more stable and consistent temperature, resulting in higher mining efficiency and lower energy consumption.

Maintaining the cooling system is critical to the success of a Bitcoin mining farm. It’s essential to monitor the temperature of the mining equipment regularly, clean the fans and ventilation system regularly to remove dust and debris that can clog the system, and ensure that the air conditioning system is functioning correctly.

Direct Evaporative Cooling

There is a cooling technology called Direct Evaporative Cooling (DEC), a type of evaporative cooling that uses water to cool the air. In DEC, hot air from the mining equipment is passed through a wet filter that cools the air as the water evaporates, reducing the temperature within the mining farm.

DEC can be an effective and energy-efficient cooling solution for Bitcoin mining farms, particularly in dry climates. However, it is less effective in areas with high humidity than in air saturated with moisture, making it easier for water to evaporate and cool the air.

Filtration

In a Bitcoin mining farm, filtration maintains a clean and healthy environment for employees. It prevents dust accumulation and other particles that can clog the mining equipment and reduce efficiency.

The primary type of filtration used in Bitcoin mining is mechanical filtration. Mechanical filtration involves using physical barriers such as air filters, screens, or meshes to remove particles from the air. Mechanical filters are commonly used in Bitcoin mining farms and effectively remove dust and other large particles from the air. Different types of filtration methods, such as electrostatic filtration, UV-C filtration, activated carbon filtration, and HEPA filtration, may also be used depending on the specific needs and circumstances of the mining farm. However, mechanical filtration is the most commonly used method in Bitcoin mining due to its effectiveness and cost efficiency.

Airflow

Facilities use different airflow mechanisms to regulate temperature and maintain a stable environment. Downflow distribution supplies cool air from the ceiling and discharges it at floor level. This mechanism is commonly used in server rooms and data centers. Upflow air distribution, on the other hand, supplies cool air from the floor and discharges it at the ceiling. It is typically used in smaller facilities, such as telecom equipment rooms.

Horizontal airflow supplies cool air through the front of the equipment and discharges hot air from the back of the equipment. This airflow mechanism is commonly used in rack-mounted equipment. Containment airflow, on the other hand, uses barriers or enclosures to contain hot and cold air separately. This mechanism can increase cooling efficiency and reduce energy costs.

Chimney airflow involves using a chimney to discharge hot air from the top of the room. This mechanism is commonly used in facilities with high ceilings. Mixed airflow combines the above mechanisms to create a customized solution based on the facility’s needs. This mechanism can help optimize cooling efficiency and reduce energy consumption.

Choosing the proper airflow mechanism depends on various factors, such as the size of the facility, the type of equipment used, and the cooling requirements. By selecting the proper airflow mechanism, facilities can optimize cooling efficiency, reduce energy consumption, and extend the life of the equipment.
