ASIC (Application-Specific Integrated Circuit)

An ASIC is a specialized computer chip designed to perform a specific task extremely efficiently—in this case, the SHA-256 algorithm used for Bitcoin mining. Unlike general-purpose CPUs or GPUs, ASICs are purpose-built for mining, offering far greater speed and energy efficiency.


ASIC Frequency

ASIC frequency is the speed at which the ASIC chip operates, typically measured in megahertz (MHz). Increasing the frequency (overclocking) can boost hashrate but also raises electricity use and heat output.


ASIC Temperature

Indicates how hot the ASIC chip gets during operation. Proper temperature control (typically aiming below 75–80°C) helps maintain performance, prevent overheating, and extend the hardware’s lifespan.


Average Hashrate

A smoothed-out measure of your miner’s performance over time, factoring in short-term fluctuations. This metric helps you gauge how consistently your miner is operating and estimate daily or monthly earnings.


Best Difficulty

The toughest share (highest difficulty) your miner has solved. Even if it doesn’t solve an entire block, a high best difficulty indicates your miner’s potential to handle more challenging shares.


Bitcoin Wallet

A tool (software or hardware) that stores your Bitcoin private keys, enabling you to receive and manage BTC. Any mining rewards you earn typically go to the Bitcoin address linked to your wallet.


Satoshis (Sats)

The smallest unit of Bitcoin, named after its creator(s), Satoshi Nakamoto. One Bitcoin equals 100,000,000 satoshis (1 BTC = 100 million sats). When you mine, your rewards can be displayed in BTC or in satoshis, depending on your wallet or pool.


Block

A container of Bitcoin transactions that miners verify and add to the blockchain. Each block references the hash of the previous block, creating a continuous, secure ledger of all transactions.


Block Reward

The block reward is the incentive miners receive for successfully mining a block. It consists of two components: the block subsidy (newly created Bitcoin) and the transaction fees collected from transactions in the block. The block subsidy halves every 210,000 blocks (approximately every four years) during an event called the Halving.

Why It Matters for Home Miners:
The block reward drives Bitcoin mining profitability. As the block subsidy reduces over time, efficient hardware and low-cost electricity become critical. Mining pools allow home miners to share in the block rewards, even if mining a block solo is improbable.


Block Template

A blueprint from a pool or node that specifies which transactions to include, the previous block hash, and other necessary data. Your miner uses this template to construct the block header it attempts to solve.


Buck Converter

A type of DC-DC power converter that steps voltage down to a stable level needed by ASICs and other components. It boosts efficiency by minimizing wasted electricity and heat.


Cold Wallet

An offline storage method for your Bitcoin private keys, such as a hardware wallet or paper wallet. Because it isn’t connected to the internet, it’s far less vulnerable to hacks.


Difficulty

A parameter that adjusts roughly every two weeks (2,016 blocks) to keep Bitcoin’s block generation at around one block every 10 minutes. Higher difficulty means miners must work harder to find valid blocks.


Efficiency

A measure of how well a mining device converts electricity into computational power, usually expressed in watts per terahash (W/TH). More efficient miners consume less electricity for the same hashrate.


Fan Speed

How fast your miner’s cooling fans spin, usually measured in RPM or as a percentage. Higher fan speeds remove heat more effectively but increase noise and power consumption.


Fallback Stratum Port

An alternative port your miner will use if the primary Stratum port becomes unreachable or fails. This ensures continuous mining and reduces downtime.


Fallback Stratum URL

A backup mining pool server address your miner will connect to if the main pool server is inaccessible. Having a fallback prevents extended periods of lost mining revenue.


Fallback Stratum User

The backup credentials (username or worker name) for mining on the fallback server. This ensures any shares sent to the fallback pool are attributed to you.


Firmware

The low-level software running on your ASIC hardware that manages operation, communication with the pool, temperature control, and other device-specific functions.


Halving

A programmed event that occurs roughly every four years (210,000 blocks), cutting the block reward in half. This limits Bitcoin’s supply growth over time and can affect mining profitability.


Hashrate

The computational power of your miner, measured in hashes per second (H/s). Most Bitcoin miners advertise terahashes per second (TH/s). A higher hashrate generally means more potential earnings.


Heatsink

A metal (often aluminum or copper) component that absorbs heat from the ASIC chip and disperses it, usually with the help of fans. Proper heat dissipation prevents overheating and hardware damage.


Hot Wallet

An online-connected wallet (e.g., on your PC or smartphone) that’s easier for frequent transactions but more exposed to hacking risks compared to a cold wallet.


Input Voltage

The voltage supplied by your wall outlet or power source—commonly 110–120V in North America or 220–240V in many other regions. Some miners can run more efficiently at higher voltages.


IP Address

A unique numerical label assigned to each device on a network (e.g., 192.168.1.100). Use it to access your miner’s interface and configure settings for pools, fan speeds, frequencies, etc.


Lightning Wallet

A wallet specialized for the Lightning Network, which facilitates fast and cheap transactions by conducting them off-chain, settling on-chain only as needed.


Measured ASIC Voltage

The real-time voltage actually delivered to your ASIC chips. Monitoring this helps ensure power stability, preventing issues from under-voltage or over-voltage.


Mining

The process of using computational power (hashrate) to solve cryptographic puzzles in Bitcoin’s Proof of Work system. Successful miners receive block rewards (newly minted BTC plus transaction fees).


Proof of Work

Bitcoin’s consensus mechanism that requires miners to do computationally intensive work—finding a block hash below the current target. This “work” secures the network and prevents fraud, as altering the blockchain would require redoing all that work.


Mining Pool

A collaborative approach where multiple miners combine their hash power to find blocks more consistently. Rewards are then split among participants based on the shares they submit.


Network

The collective term for all nodes and miners securing and validating Bitcoin transactions globally. Also refers to your local network (router, WiFi, etc.) that connects your miner to the internet.


Network Difficulty

A dynamic metric ensuring that, despite changes in the total hash power, blocks remain spaced about 10 minutes apart on average. More miners mean higher network difficulty, maintaining a stable block time.


Node

A Bitcoin software client that validates transactions and blocks. A full node stores the entire blockchain, while a mining node focuses on creating new blocks, often communicating with pools.


Overclock

Setting your ASIC to run at a higher frequency than its default specification. Overclocking increases hashrate but also raises electricity use and heat output, potentially shortening hardware lifespan.


Pool Mining

Joining a mining pool that aggregates multiple miners’ hash power, providing more frequent but smaller payouts. It’s the most common way for small-scale miners to get reliable income.


Power

Measured in watts (W), this is the total electrical energy your mining hardware consumes. Electricity cost is a major factor in determining mining profitability.


Server

In mining, a server typically refers to the pool’s Stratum server—where your miner sends shares and receives new work. A stable server connection is crucial for continuous mining.


Shares

Partial solutions that meet a lower difficulty target set by the pool. Submitting valid shares proves you’re contributing hashing power. Pools track these shares to distribute rewards fairly.


Accepted Share

A valid share that meets the pool’s difficulty target, successfully submitted to and acknowledged by the pool. Accepted shares earn you credit toward the next reward payout.


Rejected Shares

Shares submitted by your miner that the pool doesn’t accept—for example, if they arrive too late, have errors, or don’t meet the difficulty target. High rejection rates can lower your effective earnings.


Solo Mining

Mining independently, or in a solo mining pool. If you find a block, you keep the entire block reward. Given Bitcoin’s high difficulty, finding blocks solo as a home miner is rare but possible.


Stratum Protocol

The main communication method between miners and mining pools. It assigns work (block headers) to your miner and collects completed shares, coordinating mining efforts efficiently.


Stratum Port

A network port (often something like 3333 or 4444) used by the pool’s Stratum server. You specify this port in your miner’s settings so it can connect to the correct server endpoint.


Stratum URL

The mining pool’s address—e.g., stratum+tcp://pool.example.com:3333—that your miner points to. This URL plus the port tells the miner where to send and receive data.


Stratum User

Your worker identifier for the pool, often in the format [BitcoinWalletAddress].[WorkerName]. It ensures the pool attributes shares and rewards correctly to your account.


Stratum V2

An upgraded version of the Stratum Protocol, designed for improved security, efficiency, and decentralization. Although not yet universally adopted, it represents the future direction of Bitcoin mining communication.


Underclock

Running your ASIC at a lower frequency than default. While it reduces hashrate, underclocking lowers power consumption, heat, and noise—potentially improving overall efficiency (W/TH).


Voltage

The measure of electrical potential in your miner’s power system, typically 110–120V or 220–240V depending on your region. Some ASICs can automatically adjust to different voltages for optimal performance.


Voltage Regulator Temperature

Indicates how hot the voltage regulation components on your ASIC board get. Excessive heat in these regulators can cause instability or hardware failure.


Watts

A unit measuring power consumption (joules per second). By multiplying watts by the hours your miner runs, you can calculate your kilowatt-hour usage and estimate electricity costs.


WiFi SSID

The name of your wireless network. If your miner has WiFi capability, you’ll configure it to connect using the correct SSID (and password) to maintain a stable internet connection.


Inductor

A passive electronic component that stores energy in a magnetic field when current flows through it. In miner power supplies, inductors help smooth out voltage and current, reducing electrical noise and spikes.


ESP Microcontroller

A low-cost, WiFi-enabled microcontroller (e.g., ESP8266 or ESP32) sometimes used in DIY or experimental mining setups (like Bitaxe). It can manage network connections and basic control features for the ASIC.


PCB (Printed Circuit Board)

The board on which all electronic components of your miner (ASIC chips, voltage regulators, inductors, etc.) are mounted. Its design affects signal integrity, cooling, and overall reliability.


BAP (Bitaxe Accessory Port)

A specialized connector found on certain open-source or DIY mining hardware (like Bitaxe), allowing users to attach modules or accessories (e.g., extra sensors or display boards) for extended functionality.


Solder

A fusible metal alloy (commonly tin-lead or lead-free) used to join electronic components onto a PCB. If you’re assembling or repairing your own mining hardware, you’ll use solder to secure parts electrically and mechanically.


PWM Fan Connection

A 4-pin interface allowing pulse-width modulation (PWM) control of fan speed. This lets the firmware dynamically adjust fan RPM based on temperature, striking a balance between cooling performance and noise/power usage.


Simple Formulas for Bitcoin Miners

  • Calculate Power (Watts):
    Watts (W) = Voltage (V) × Current (A)
    Example: A miner running at 220V with 10A:
    220 × 10 = 2200W

 

  • Calculate Current (Amps):
    Current (A) = Watts (W) ÷ Voltage (V)
    Example: A miner consuming 2400W at 120V:
    2400 ÷ 120 = 20A

 

  • Estimate Energy Costs:
    Cost = Watts (W) × Hours Operated × Electricity Rate ÷ 1000
    Example: A miner using 2200W, running 24 hours/day, with an electricity rate of $0.12/kWh:
    2200 × 24 × 0.12 ÷ 1000 = $6.34/day
