The algorithm behind every Bitcoin ASIC
SHA-256 is a 256-bit cryptographic hash that maps any input to a fixed-length digest and resists preimage, second-preimage, and collision attacks under current knowledge. In Bitcoin it anchors Proof of Work as miners hash the 80-byte block header twice with SHA-256 until the result falls below a target encoded in nBits. They sweep the search space by changing the nonce, the timestamp, and the coinbase so the Merkle root shifts, while the header fields sit under a cold, exacting focus. A valid block appears when the double-hash is numerically less than the target, which defines difficulty and the expected effort. Bitcoin adjusts difficulty every 2016 blocks to keep the average block time near ten minutes as network hash rate moves. The double application of SHA-256 also dampens length extension issues that affect Merkle–Damgård designs when a digest is reused as an identifier. SHA-256 is compute-bound and light on memory, so ASICs can unroll and pipeline the 64 rounds for extreme throughput, while GPUs and CPUs lag on efficiency. This optimization lifts security through higher aggregate work yet pushes energy demand and can concentrate mining in large operations. Pools reduce payout variance but introduce coordination and fee overhead. Miner profitability hinges on device hash rate, energy efficiency in joules per terahash, electricity mix, uptime, pool fees, orphan risk, transaction-fee share, and halving events that cut the block subsidy about every 210,000 blocks. Beyond mining, SHA-256 supports digital signatures by hashing messages, secures certificate chains, verifies firmware and software integrity, and guards data at rest or in transit. No practical collisions are known, and reversing a digest remains infeasible on classical hardware. Quantum search could yield a square-root speedup for preimages, which lowers effective security, yet the 256-bit space leaves a broad safety margin today. Under this steady cadence of work and retargeting, blocks arrive with clockwork restraint while the ledger records transactions with a traceable cost.
What a SHA-256 ASIC actually earns
Every SHA-256 ASIC in the table above competes for the same Bitcoin block reward, so the only two numbers that separate a profitable miner from an expensive space heater are how many terahashes it produces and how many joules it burns to produce each one. Hashprice, the revenue one terahash per second earns in a day, is set by the network for everyone; efficiency in joules per terahash is set by the chip in your hands.
That is why the ranking on this page is driven by profit at your electricity rate rather than by raw hashrate. A 400 TH/s machine at 30 J/TH and a 200 TH/s machine at 15 J/TH pull the same power from the wall; the first earns twice as much revenue but only if its extra terahashes cost you nothing to run. The break-even ladder below shows where that trade-off flips for your own kilowatt-hour price.
Each halving cuts the block reward in half and each difficulty adjustment moves the target every two weeks, so the same ASIC can be comfortably profitable in one epoch and marginal in the next. The figures on this page update with the network; bookmark it and check back after the next adjustment rather than trusting a screenshot.

The electricity price each efficiency class can survive
At today's hashprice, this is the highest kilowatt-hour price at which a miner of a given efficiency still covers its power bill. Your own rate is marked.
Efficiency generations at a glance
Each generation cut the joules per terahash roughly in half; a longer bar means fewer joules per terahash. Where a miner sits on this ladder decides whether it survives the next halving.

These figures track two different things: the Bitcoin difficulty adjustment cycle, and the network's actual current state. Progress, Remaining Block, Remaining Time, and Next Change all describe the adjustment cycle itself. Right now the cycle is 88.74 % complete. 227 blocks remain — roughly 1 day 13 hours. Estimated next difficulty adjustment: -0.1 %. Block Time is the current average time between mined blocks (10.0 minutes). Network Difficulty and Network Hashrate are different: they show the network's actual current values rather than progress toward a future recalculation. Bitcoin's network difficulty is currently 132.76 T, and the total network hashrate securing it is 974.68 EH/s. Higher difficulty and hashrate mean more competition for the same block reward, which directly lowers per-miner Bitcoin mining profit at any given hashrate. Our ASIC mining profit calculation factors all of this in automatically, so every profitability figure on this page already reflects current network conditions.
About the SHA-256 algorithm
SHA-256, the 256-bit member of the SHA-2 family standardized by NIST in 2001, forges a fixed-length fingerprint from data of any size and stands as a one-way gate whose preimage resistance is on the order of 2^256 and collision resistance about 2^128, with an avalanche effect that scatters even a single-bit change across the whole digest; built on a Merkle–Damgård construction with a dedicated 64‑round compression function over 512‑bit blocks, it relies on simple, fast 32‑bit operations (rotates, shifts, choice, majority) and constants derived from fractional prime roots, and while reduced‑round cryptanalysis exists in the literature, there are no practical collisions known, which is why SHA‑256 anchors digital signatures, HMACs, software integrity checks, firmware updates, and modern certificate chains in everyday security systems; in Bitcoin it is applied twice to the 80‑byte block header as proof of work, with miners iterating the nonce and adjusting the coinbase‑driven Merkle root (the so‑called extraNonce technique) until the resulting hash falls below a target encoded in nBits, a target that retunes roughly every 2016 blocks to stabilize block intervals, and this mechanical ritual-part competition, part bulwark-enforces ordering of transactions and makes double‑spending or long‑range reorganizations prohibitively costly; compared with memory‑hard designs like Scrypt or Ethash, SHA‑256 is light on memory and thus highly ASIC‑friendly, spawning specialized hardware whose efficiency is tracked in joules per terahash and whose rise has concentrated hash power into industrial fleets and pools coordinated by protocols such as Stratum, yet the open contest for blocks, the ease of verification for every node, and the sheer expense of amassing majority influence continue to hold the line for decentralization; beyond block headers, Bitcoin employs double SHA‑256 for transaction IDs and Merkle trees, and more broadly the function underpins commitment schemes, randomness beacons, and key derivation when wrapped in HMAC (as in widely used constructions like HKDF), so that many voices can argue-some warning that centralization is a slow encirclement, others insisting that thermodynamics and market churn keep any single commander from the field-but the hash remains indifferent, a mute sentinel reducing chaos to 256 bits, and in that indifference lies integrity: transparent verification at massive scale, practical resistance to tampering, and a predictable race that miners analyze with profitability models balancing hardware efficiency, energy use, and difficulty trends, even as the network gathers their work into a ledger whose security rests, quietly and stubbornly, on the unyielding math of SHA‑256.
Air, hydro or immersion for SHA-256
The same SHA-256 chip ships in three kinds of enclosure, and the enclosure decides where you can run it, how loud it is and how hard it can be pushed.
Air-cooled
Fans pull room air across the hashboards. It is the cheapest way in and the only sensible choice for a single machine, but it is loud, it needs somewhere to dump the heat and it usually runs a few joules per terahash above the same chip in a liquid enclosure.
Hydro-cooled
Water blocks sit on the chips and a chiller or dry cooler carries the heat outside. Hydro units run quieter, denser and slightly more efficient than air, and most flagship SHA-256 models now ship a hydro variant first. The plumbing and the minimum order size push it toward containers and farms.
Immersion
Whole hashboards sit in a tank of dielectric fluid. It removes fans entirely, tolerates hot climates and allows the deepest overclocks, at the cost of specialised tanks, fluid handling and a warranty conversation with the manufacturer.
What a year with today's top miner looks like
The most profitable SHA-256 miner in the table right now, at your electricity rate, is shown on the right. The projection simply multiplies today's daily profit out, which is exactly what every mining calculator does and exactly why they all overstate the result.
Over a real year the network hashrate tends to climb, the difficulty follows it, and the Bitcoin price moves both ways. Treat the yearly figure as the ceiling for a flat market, then ask what happens if difficulty grows a few percent per adjustment and whether a halving falls inside your payback window.
