Alephium mining in 2026: is Blake3 still worth it?

Every Alephium ASIC on the market breaks even below 3.6 cents per kilowatt-hour. Not "is marginal above" — breaks even. Above that rate, every single one loses money on electricity alone, before you account for what the hardware cost.

That is an uncomfortable opening for a page on a shop that sells Alephium miners, so let us be precise about what it does and doesn't mean. Blake3 mining is dead at any domestic tariff in Europe. It is not dead at industrial rates. The gap between those two statements is the entire subject of this article, and it is worth understanding properly before you spend anything.

All figures observed 31 August 2026. If you want the hardware list first, it is on the Alephium miners page.

Where ALPH actually stands

That last row deserves a moment. The entire Alephium network — every miner, everywhere — is competing for about a thousand dollars a day. For comparison, Kaspa's is around $54,500.

Three things about Alephium that most articles get wrong

There is no halving. Alephium's block reward is computed per block as the lower of a time-based curve and a hashrate-based curve. It does not step down on a schedule you can diarise. Today the reward sits around 0.115–0.144 ALPH depending on which tracker you ask. Alephium's own mining docs still quote 0.1915 — that figure is stale, and if a calculator is using it your earnings estimate is roughly 30% too high.

The 1 billion supply cap no longer exists. The Danube upgrade, live on mainnet since 15 July 2025, removed it. ALPH now has uncapped tail emission, in the same spirit as Monero, to avoid a security cliff when the subsidy would otherwise have run out. Danube also halved block time from 16 to 8 seconds, which roughly halved the per-block reward. Plenty of pages written before mid-2025 still describe a capped supply.

Proof of Less Work has never activated. This is the chain's headline differentiator and the source of the "87% less energy than Bitcoin" line you will see repeated everywhere. PoLW only triggers when total network hashrate reaches 1 EH/s. At roughly 5 PH/s, Alephium is at 0.55% of that threshold. Today it is plain Nakamoto proof-of-work like any other chain. The energy claim is a future conditional being quoted as a present fact.

Worth knowing what happens if it ever does fire: miners would have to burn ALPH as a coinbase input on hashrate above the threshold — meaning you would need to already hold the coin in order to mine it. That is a significant design choice, and one nobody has had to live with yet.

Every Alephium miner and its break-even

Nothing new has shipped on Blake3 since November 2024. The entire fleet is around two years old.

The arithmetic, using the AL3: 15 Th/s × 5.178 ALPH = 77.7 ALPH/day, at $0.0375 that is $2.93. It draws 3.5 kW, so 84 kWh/day. Break-even is 2.93 ÷ 84 = $0.0349/kWh. At a European domestic rate of 25 cents it loses over $18 a day.

Even ignoring electricity entirely, an AL3 at around $1,800 grossing $2.93 a day takes more than 600 days to return its purchase price — and that assumes price and difficulty both stand still, which they will not.

The liquidity problem nobody mentions

Alephium trades about $231,000 a day across every venue combined. The deepest book is MEXC at roughly $102k, then Bitget and Gate around $50k each. There is no Binance, Coinbase, Kraken or OKX listing. On-chain liquidity via Uniswap is under $2k a day.

For one machine this is irrelevant — an AL3 mines about 78 ALPH a day, worth under $3. For anything at scale it is the binding constraint. A hundred AL3s produce around 7,800 ALPH daily, roughly 3% of global daily volume. You would be moving the price against yourself every time you cashed out. Any plan that involves a rack of Blake3 machines needs a selling strategy before it needs a hosting contract.

Alephium or Kaspa? Kaspa, and it isn't close

These two get compared constantly — both are "next-generation" proof-of-work alt-L1s with dedicated ASICs. Revenue per terahash is genuinely similar. The hardware is not.

Kaspa's best silicon is 3.4 times more efficient and tolerates a break-even rate 2.7 times higher. Kaspa also has a stream of new SKUs shipping into 2026 while Blake3 has had nothing new for nearly two years, and KAS carries a $753m market cap against ALPH's $5m.

This is a structural hardware-generation gap, not a price wobble — it would take roughly a 3.5× move in the ALPH/KAS ratio to flip the ranking. If you are choosing between them purely on economics, the Kaspa side is the answer today.

So when does an Alephium miner make sense?

Three honest cases, and one non-case.

You believe ALPH is mispriced. Down 99% from its high, mining is a way to accumulate at production cost rather than buying on a thin order book. That is a conviction trade, not a yield calculation, and it should be sized accordingly.

You have industrial power. Below 3.5 cents, the AL3 and the Bitmain AL1 pair are genuinely cash-positive. This is the only version of Alephium mining that works as arithmetic rather than as a bet. For reference, our cheapest facility runs at $0.0072/kWh — at that rate an AL3 grosses $2.93 and pays about $0.60 in power, leaving roughly $2.33 a day. That is a real margin on a machine most people cannot run at all.

You want a small, quiet machine to learn on. The AL2 Lite at 500 W runs from a wall socket and costs a few hundred dollars. As an education in pools, payouts and firmware it is cheap. As an investment it is not.

The non-case: running any Blake3 machine on a domestic tariff. At 25–30 cents per kWh an AL3 loses more than $18 a day. There is no configuration, pool or firmware tweak that fixes a 7× gap.

Pools and where the hashrate actually is

Worth noting plainly: the two pools that publish figures account for under a quarter of network hashrate. Where the other ~75% sits, we could not verify. On a network this small that is a centralisation question worth asking before you commit hardware to it.

Price and supply data from CoinGecko; network and pool figures from minerstat, HeroMiners, Kryptex and WoolyPooly; hardware specifications from ASIC Miner Value; protocol details from Alephium's tokenomics paper and Danube upgrade documentation — all observed 31 August 2026. Mining profitability is never guaranteed and ALPH is unusually illiquid; check the calculator against your own power price before buying.
