Litecoin hashrate: correcting the 3.5 PH/s record claim
Why a hashrate record needs a consistent source and averaging window, and how to interpret mining estimates.

The earlier headline called 3.5 PH/s a new all-time high. That comparison was not adequately supported and has been withdrawn. This correction preserves the original publication date.
Why the record claim was wrong
The Litecoin Foundation's 2025 review reports a daily-average peak of 3.827 PH/s on 6 December 2025, attributed to CoinWarz. A later 3.5 PH/s observation cannot establish a higher record on that same basis.
Compare the same measurement
| Required field | Why it matters |
|---|---|
| Provider and series | Different estimators can report different values. |
| Observation time | A present value is not the value at publication. |
| Averaging window | An instantaneous estimate, daily mean and weekly mean are not interchangeable. |
| Units | 1 PH/s equals 1,000 TH/s or 1,000,000 GH/s. |
| Historical comparison | A record needs the preceding history from the same series. |
Hashrate and security
Hashrate is estimated from observed proof-of-work, difficulty and block timing; it is not a direct inventory of every machine. A short run of fast blocks can lift an estimate without demonstrating an equivalent permanent increase in equipment.
Higher hashrate alone does not establish a precise dollar cost for an attack. Available hardware, rental-market depth, miner behavior, duration and network conditions also matter. The earlier attack-cost figures and claims that merchants can automatically lower confirmation requirements have been removed.
Profitability needs dated inputs
ASIC profitability depends on purchase cost, wall-power consumption, electricity price, pool fees, uptime, difficulty, exchange rates and merged-mining proceeds. A device specification is not a verified profit forecast. The earlier equipment and payback tables lacked enough source detail to reproduce their results and were withdrawn.
