Crypto Mining Glossary

A payout threshold in Bitcoin mining refers to the minimum amount of cryptocurrency a miner must accumulate before they can request a payout from a mining pool. This threshold is set by the pool to minimize transaction fees and administrative overhead. Once a miner's earnings meet or exceed the payout threshold, the pool will process the payout and transfer the funds to the miner’s wallet.

Pool centralization refers to the concentration of mining power in a few large mining pools, leading to reduced decentralization in the Bitcoin network. When a small number of pools control a significant portion of the network’s hashrate, they can potentially exert influence over block production, transaction validation, and other aspects of the network. High pool centralization can undermine the principles of decentralization.

A pool fee is the percentage of the rewards that a mining pool operator takes for managing the pool’s operations, including maintaining servers, security, and payouts. Mining pools charge these fees to cover their costs, and the fee typically ranges from 1% to 3% of the total rewards. The fee is deducted before rewards are distributed to the individual miners based on their contribution to the pool’s mining efforts.

Pool hashrate refers to the combined computational power of all miners in a mining pool. It is the total number of hashes the pool can compute per second, measured in terahashes per second (TH/s). A higher pool hashrate increases the pool’s chances of solving a block and earning mining rewards, as it allows the pool to perform more hash calculations faster, making the mining process more efficient.

Pool luck is a measure of how often a mining pool successfully mines a block compared to its expected rate based on the pool’s hashrate. Pool luck reflects the randomness and variability in the process of solving blocks. It is calculated by comparing the actual block mining rate to the expected rate. A pool's luck can be higher or lower than expected due to the inherent randomness.

Pool mining is the process of miners combining their computational power to work together on solving the cryptographic puzzles required to add a new block to the Bitcoin blockchain. In a mining pool, miners share their resources and the rewards based on their contribution.

A pool server in Bitcoin mining is a server that manages communication between miners and mining pools. It distributes mining tasks to connected miners, collects the results (shares) submitted by miners, and communicates the pool’s mining work. The pool server also handles reward distribution, ensuring that miners receive their share of the pool’s earnings once a block is successfully mined.

Power consumption (wattage) refers to the amount of electrical energy that a Bitcoin miner uses to operate. It is measured in watts (W) and is a critical factor in determining the efficiency and profitability of mining hardware. The higher the power consumption, the more electricity a miner uses.

A Power Supply Unit (PSU) is a crucial component in a Bitcoin mining rig that converts electrical power from the wall outlet (AC power) into the appropriate DC power required by mining hardware, such as ASIC miners or GPUs. The PSU provides the necessary voltage and current to run the mining device.

PPLNS (Pay Per Last N Shares) is a payout model used by mining pools to distribute rewards to miners. In the PPLNS model, miners are paid based on the number of shares they contribute over a specific period, known as the "last N shares" window. This model emphasizes the contribution made during a defined period rather than just the shares submitted for a particular block.

PPS (Pay Per Share) is a payout model used by mining pools to distribute rewards to miners. In the PPS model, miners are paid a fixed amount for each share they contribute to the pool, regardless of whether the pool successfully mines a block. This system ensures consistent payouts and reduces the variability in miner earnings, providing a more predictable and stable income stream for participants.

Proof of Work is a consensus mechanism used in blockchain networks where miners compete to solve complex cryptographic puzzles to validate transactions and add new blocks. It requires computational effort and energy. In Bitcoin, PoW determines who creates the next block and earns the block reward.

PROP (Proportional Reward) is a mining pool payout model where miners are rewarded based on the proportion of shares they contribute to the pool relative to the total shares submitted by all miners. In the PROP system, miners receive a percentage of the total reward (block reward + transaction fees) in direct proportion to their share of the pool’s total work.
