Mining

The amount of SHA-256 computation a miner or pool performs each second. Higher hash rate improves the chance of earning block rewards.

Bitcoin's automatic adjustment that keeps blocks arriving roughly every ten minutes as total network hash rate changes.

A shared mining service where participants combine hash rate and split rewards, reducing payout variance compared with solo mining.

Purpose-built mining hardware designed for a specific algorithm such as SHA-256. ASICs are far more efficient than general computers.

The miner payout for a valid block. It includes the block subsidy plus transaction fees.

A programmed event that cuts Bitcoin's block subsidy in half about every four years. The current subsidy is 3.125 BTC per block.

A transaction has one confirmation when it is included in a block. Each later block adds another confirmation.

A public destination used to receive bitcoin. It is safe to share, but must be copied exactly.

Mining hardware operated in a managed facility, so the customer does not handle power, cooling, noise, or maintenance.

A named worker account at a mining pool. It helps route mining shares and reporting to the correct customer setup.

A service interruption that affects mining connectivity or reporting. Planned maintenance and customer-side issues should be tracked separately.

An estimate based on hash rate, difficulty, fees, uptime, and bitcoin price. It is not a guaranteed return.
