How hash rate (TH/s) works

Hash rate counts how many SHA-256 attempts per second a miner can throw at the search for a valid block. The unit ladder climbs like this: 1 TH/s = 10¹² H/s, 1 PH/s = 10¹⁵, 1 EH/s = 10¹⁸. A modern Antminer S21 puts out ~200 TH/s, while the full Bitcoin network sits around 600 EH/s. Your odds of mining the next block solo work out to hash_yours / hash_network. Run the math: 200 TH/s against 600 EH/s is 3.3·10⁻⁷, which translates to about 3 million blocks, or roughly 60 years, for one Antminer to land a block on its own.

Applications

Pool mining (Foundry USA, AntPool, F2Pool), where lots of small miners split the reward in proportion to the shares they submit. Sizing a home ASIC, where you weigh an S19j Pro (100 TH/s) against an S21 (200 TH/s) by what your outlet amperage can handle. And ROI projections that fold together hash rate, hash price (USD per TH/day) and what you pay for electricity.

FAQ

Solo or pool? If your personal capacity is under ~1 EH/s, go pool every time. Solo mining is basically a lottery. The variance is enormous, and the expected income is the same as a pool would give you minus the pool fee (1-3%).

Why does TH/s alone not predict profit? Revenue also leans on network difficulty, the BTC price and your J/TH efficiency. Put two miners side by side with the same TH/s but different watt draw and their bottom lines look nothing alike.

Is GPU hash rate the same unit? Same physics, but a GPU manages only ~1 GH/s of SHA-256, about 200,000× weaker than an ASIC. The only place GPUs pay off is memory-hard algorithms (Ethash legacy, KawPow, RandomX).
