Crypto Mining Glossary

An uncle block is a valid block in Ethereum that is mined but not included in the main blockchain because another block at the same height has already been added. Unlike orphan blocks in Bitcoin, uncle blocks are accepted by the Ethereum network and reward miners with a smaller incentive.

Undervolting is the practice of reducing the voltage supplied to a mining device's hardware components (such as ASIC chips or GPUs) while maintaining stable performance. In Bitcoin mining, undervolting helps lower power consumption, reduce heat generation, and improve the energy efficiency of the mining rig, ultimately enhancing profitability and extending hardware lifespan.
