Kaspa's hashrate is the total computing power miners aim at the network every second. It is produced almost entirely by purpose-built ASIC machines running Kaspa's own algorithm, kHeavyHash. The live figure is below. The number matters because it is a price tag: it tells you roughly what it would cost to attack the chain — and rebuilding this much specialised hardware is not something an attacker does quietly.
Every second, each mining machine makes billions of attempts at solving the current block. Hashrate is the sum of all those attempts across every machine in the world pointed at Kaspa. More hashrate means an attacker needs more physical hardware and more electricity to overpower the honest majority.
That's why hashrate is best read as a security budget. It represents real capital — machines bought, facilities built, power contracts signed — committed by people who only earn their money back if the network keeps running honestly. Like TVL for smart contracts, it is a number someone has to pay for, which is what makes it hard to fake.
What hashrate is not: it is not adoption, not transaction demand, and not a price signal. A chain can have enormous hashrate and empty blocks, or modest hashrate and a busy economy. It measures the wall around the city, not the life inside it.
One thing that does not affect the hashrate: merged mining. Networks like ZKas reuse the exact same kHeavyHash work Kaspa miners already produce, so no mining power leaves Kaspa — participating requires mining Kaspa. We explain the mechanism in full in Kaspa merged mining, explained.
These apply to every proof-of-work chain, and they're the reason hashrate headlines mislead so reliably.
A kHeavyHash hash and a SHA-256 hash are different computations on different hardware. Saying "Bitcoin has thousands of times Kaspa's hashrate" is like comparing kilometres to kilograms — the units don't convert. What is comparable across chains is the economics: how much real hardware and electricity stands behind each network. The table below shows the raw factor anyway, because you'll see it quoted everywhere — just read it as a statement of scale, never as a security ratio.
Miners are businesses. When the coin price falls, margins compress, and the least efficient machines eventually shut off — weeks or months later, once hosting contracts and hope run out. A falling hashrate usually tells you about yesterday's miner economics, not tomorrow's network health. The same works in reverse: hashrate keeps climbing long after a rally starts, as ordered machines come online.
Total hashrate says nothing about how it's distributed. A network where three pools control the majority of blocks has a different risk profile than one with dozens of independent operators, at identical total hashrate. When you evaluate security, ask both questions: how big is the wall, and how many hands hold it.
Both figures are fetched live, so this table is current whenever you're reading it. Remember trap number one: the factor is scale, not security.

Bitcoin's SHA-256 network is the largest computing effort in crypto and has a 12-year head start in ASIC development. The honest reading for Kaspa: it is secured by a dedicated, single-purpose ASIC fleet — which is the strongest form of proof-of-work security a young chain can have, because that hardware is useless for anything except mining kHeavyHash. An attacker can't rent it from a general-purpose market the way GPU-mined chains can be attacked.
The absolute number is a headline. Four readings carry actual information:
