Definition ∞ Exahash per second (EH/s) is a unit of measurement indicating the computational power used in cryptocurrency mining, particularly for Proof-of-Work blockchains like Bitcoin. One exahash represents one quintillion hashes per second, signifying an immense number of calculations performed. A higher EH/s value indicates greater network security and a more robust mining operation. This metric reflects the collective effort of all miners validating transactions.
Context ∞ News reports frequently cite exahash per second to assess the health and security of Proof-of-Work networks. Discussions often link EH/s to miner profitability, energy consumption, and geographical distribution of mining activities. A critical future development to observe is the continued growth and decentralization of global hashing power, impacting network resilience and environmental considerations.
