Alephium combines Bitcoin-style transaction security (the UTXO model) with smart contract capabilities, making it one of the few proof-of-work blockchains that supports programmable applications without abandoning the security properties miners rely on. The MillionMiner catalog covers 14 current Alephium models, led by the Bitmain AL3 series and variants. Mining uses the Blake3 algorithm. Blake3 ASICs deliver competitive efficiency in the 15 to 20 J/TH range, comparable to mid-tier SHA-256 hardware while operating on a far less saturated network. Lower competition at the network level means newer entrants face shorter waits for block rewards relative to invested hashrate. Alephium attracts buyers who want exposure to a smaller PoW chain with smart contract upside, without committing to highly experimental hardware. The Bitmain AL3 line is well documented, supplied through standard manufacturer channels, and supported by MillionMiner's hosting infrastructure. Every miner ships DDP and qualifies for hosting at MillionMiner's US facilities.

Alephium (ALPH) is a next-generation layer-1 blockchain that combines proof-of-work security with sharding technology to deliver scalable, programmable infrastructure. Unlike most "scalable" blockchains that abandoned PoW entirely, Alephium proves that mining and high throughput can coexist. Powered by the Blake3 hashing algorithm and its novel BlockFlow sharding architecture, ALPH is mined by a growing fleet of dedicated ASICs and represents one of the most technically sophisticated new mining opportunities available today.

The ALPH ASIC market matures. GPU mining becomes marginal. Purpose-built Blake3 machines deliver dramatically superior efficiency.
Most blockchain projects that wanted scalability abandoned proof-of-work. Alephium took a different path: it built a sharded PoW blockchain from scratch. The result is a network that can process thousands of transactions per second while maintaining the full security model of mined proof-of-work — no validators, no staking, no trusted committees.
At the core of Alephium is BlockFlow — a novel sharding algorithm that divides the network into 16 shard groups, each producing blocks concurrently and cross-referencing each other through a DAG-like dependency system. Transactions route automatically to the correct shard, and the entire system settles with full finality without sacrificing decentralisation or mining security.
Unlike Kaspa's GHOSTDAG approach (which parallelises blocks on a single chain), Alephium's sharding genuinely partitions state and execution across 16 independent groups. This is a fundamentally different architectural approach — one that positions ALPH as both a serious mining coin and a credible smart contract platform for the next generation of decentralised applications.
Alephium's architecture is unlike any other mineable blockchain. Understanding it helps you appreciate why ALPH is a genuinely long-term viable mining target.

Each of the 16 shard groups produces blocks concurrently. Your ASIC's hashrate contributes to all groups simultaneously through work distribution by your pool.
Each group maintains independent state and block production.
Blocks reference headers from sibling shards, ensuring global consistency.
Transactions reach finality without requiring a separate finality layer.
Your miner's work secures all 16 groups — no fragmentation of mining power.
Alephium introduces a hybrid "stateful UTXO" model that combines Bitcoin-style UTXO security with the programmability of Ethereum's account model. Smart contracts can own state and assets directly, eliminating entire classes of vulnerabilities present in EVM-based systems like reentrancy attacks.
Alephium's custom smart contract language Ralph was designed specifically for security and predictable gas costs. Unlike Solidity's often surprising gas behaviour, Ralph contracts are easier to audit and harder to exploit — an important differentiator for DeFi applications built on Alephium's PoW infrastructure.
Alephium implements a unique "Proof-of-Less-Work" mechanism that activates when the network hashrate exceeds a certain threshold. At high hashrate, miners can burn ALPH tokens to reduce the required computational work — a built-in energy efficiency mechanism that aligns miner incentives with network sustainability.
Alephium's choice of Blake3 as its proof-of-work algorithm was a deliberate engineering decision — and one that makes ALPH ASICs among the most power-efficient mining hardware ever produced.
Blake3 is the successor to Blake2 and SHA-3 finalist Blake. On modern hardware it is 3–10× faster than SHA-256 and dramatically faster than memory-hard algorithms like Etchash or Scrypt. On purpose-built ASIC silicon it achieves extraordinary throughput at very low power — which is why ALPH miners achieve TH/s-level hashrates with sub-100W power draws on compact units.
Blake3 is based on the Merkle tree construction with the BLAKE2s compression function at its core. It has been formally verified and is used in production security systems worldwide — not just crypto mining. Its security margin is extremely well understood and far exceeds what is needed for PoW applications, making it a robust long-term algorithm choice.
Because Blake3 is compute-bound rather than memory-bound, ASIC designers can pack enormous hashing throughput into very small chip areas with minimal power overhead. The result: ALPH ASICs like the iPollo G1 mini achieve competitive hashrates at power draws that are a fraction of Bitcoin or Etchash equivalents — making them extremely accessible for home miners.
Block rewards and transaction fees land in your self-custody ALPH wallet on your pool's payout schedule. With Alephium's ~64-second block time across 16 shards, blocks accumulate rapidly and pool payouts are consistent and predictable. No custodian. Your ALPH, your keys.
Alephium launched with a total supply cap of 1 billion ALPH. Of this, 140 million ALPH was pre-mined at genesis for the ecosystem fund, team, and future development — the remaining 860 million ALPH is distributed entirely through mining over a period projected to last over 80 years. This long emission tail is by design: it ensures miners have meaningful block reward income for generations, not just a few years.
Block rewards in Alephium are not halved on a fixed schedule. Instead, the reward decreases gradually through a continuous algorithmic function tied to the circulating supply. As more ALPH is mined and circulates, the per-block reward decreases smoothly — similar in concept to Kaspa's chromatic schedule but calculated differently. There are no sudden halving cliffs to model around.
For miners, the long emission tail and gradual reduction schedule make ALPH one of the most long-term stable mining income profiles available. Hardware purchased today will still earn meaningful block rewards years from now — a compelling argument for ALPH as a portfolio addition to more halving-sensitive coins like BTC or LTC.

Where does ALPH fit in a diversified mining portfolio? Here's a direct comparison of key protocol characteristics.
Alephium is the only PoW chain in this comparison that supports programmable smart contracts natively — making it unique in the mineable coin landscape as both a mining asset and a DeFi platform.
Alephium is one of the most home-friendly ASIC mining coins available today. Because Blake3 is compute-efficient rather than power-hungry, entry-level ALPH ASICs like the iPollo G1 mini operate at around 400–600W — a fraction of what a Bitcoin or Etchash ASIC demands. This means you can run multiple ALPH miners from a standard home electrical circuit without dedicated wiring or industrial power infrastructure.
Noise levels are also lower than equivalent-revenue Bitcoin miners due to the reduced heat output. A small ALPH mining setup of 2–4 units in a spare room or garage is entirely practical for most home miners. The ASIC market is still young and growing — early positions in the ALPH network hashrate carry a different risk-reward profile than entering the mature, saturated Bitcoin mining market.
The Alephium ASIC market is still in its early stages compared to Bitcoin or Litecoin. Miners who deploy significant hashrate now — while network difficulty is still manageable and ASIC hardware is not yet dominated by a single large manufacturer — can establish a meaningful share of the network before the inevitable influx of institutional-scale operations.
The low per-unit power draw of ALPH ASICs also means you can deploy more units within a given power contract compared to Bitcoin miners. A 100kW colocation allocation that would host roughly 28 Antminer S21 Pro units could host 150–200 ALPH miners of comparable total hashrate-to-revenue at current prices.
The ALPH ASIC market is younger than Bitcoin or Kaspa but growing quickly. Three metrics determine your choice.
Alephium hashrate is expressed in TH/s (terahashes per second). Entry-level units like the iPollo G1 mini start around 3–6 TH/s, while higher-end machines reach 40+ TH/s. Because the ASIC market is still relatively new, even modest hashrate positions currently represent a meaningful share of the network.
Higher = More ALPHALPH miners are refreshingly low-power compared to BTC or ETC equivalents. Entry models run at 200–600W. This low power draw is not just good for home miners — it directly improves your J/TH ratio (electricity cost per unit of hashrate) and makes your operation more resilient during ALPH price dips.
Lower = Home FriendlyBecause the ALPH ASIC market is still young, even a modest hashrate deployment today represents a larger network share than equivalent spend in BTC or KAS. Calculate your ROI using current ALPH price, daily block reward, your share of network hashrate, and your electricity cost — always projecting forward with difficulty growth assumptions.
Early Market OpportunityALPH mining profitability is shaped by four core variables plus one unique factor specific to Alephium's architecture. Understand all five and you'll model your returns accurately.
ALPH is a smaller-cap asset with higher price volatility than Bitcoin or even Kaspa. This creates asymmetric upside potential for miners who accumulate during low-price periods — but also higher risk during sustained bear markets. Miners with electricity costs below $0.06/kWh can typically remain profitable across a wide ALPH price range. Those on residential power are more exposed to price swings and should model their break-even carefully before investing in hardware.
The ALPH ASIC market is still in its early growth phase. New machines continue to come to market and the network hashrate is growing — which means difficulty is growing and each miner's proportional share of rewards is declining over time. This is the normal trajectory for any PoW coin transitioning from GPU to ASIC dominance. Model conservatively: assume difficulty doubles from today within 12–18 months as more ASIC deployments come online globally.
Because ALPH ASICs draw much less power than Bitcoin miners (200–600W vs 3,000–4,000W), the absolute daily electricity cost per machine is very low. An iPollo G1 mini at 500W costs just $0.48/day at $0.04/kWh and $1.44/day at $0.12/kWh. This lower absolute cost makes ALPH mining more forgiving on residential power than BTC or ETC mining — but efficiency still matters. Always calculate net profit (revenue minus power) rather than gross revenue.
Unlike Bitcoin's sudden halvings, ALPH block rewards decrease continuously according to an algorithmic function tied to the circulating supply. The rate of decrease is gradual but cumulative — over a year, your daily ALPH output will be measurably lower than today even at constant difficulty. Include this decay in your long-term models. The good news is that the emission tail extends over 80+ years, so the decay rate is extremely slow compared to coins with 4-year halving cycles.
Alephium's PoLW mechanism activates when the network hashrate reaches a threshold defined by the protocol. At that point, miners can optionally burn ALPH to reduce their required hashrate contribution — effectively subsidising security with coin burning rather than pure electricity expenditure. This mechanism is not yet active at current hashrate levels, but it is an important consideration for long-term miners: once active, it changes the economics of mining by introducing a coin-burn component alongside electricity cost.
The ALPH pool ecosystem is smaller but well-established. Because Alephium's sharded architecture requires pool software that understands BlockFlow's multi-group block structure, not all generic mining pool software supports ALPH. The pools below have all implemented native Alephium support and are trusted by the community.
One important note for ALPH: the network produces blocks across 16 shard groups simultaneously. Your pool handles the complexity of submitting work across all groups — you simply point your miner at the pool's ALPH stratum endpoint and configure your ALPH wallet address. Check the pool's minimum payout threshold before connecting, as ALPH's per-block reward is lower in fiat terms than BTC, meaning payout intervals may be longer on small setups.

ALPH's unique architecture and young ASIC market create pitfalls that are easy to avoid once you know what to look for.
Using a Pool That Doesn't Support BlockFlow
Not all generic mining pools support Alephium's sharded BlockFlow architecture. Using an incompatible pool will result in failed shares or no payouts. Always verify the pool explicitly lists ALPH/Alephium support and has an active ALPH stratum endpoint before connecting your hardware.
Projecting Returns Without Difficulty Growth
The ALPH ASIC market is in rapid growth. New hardware from iPollo, Goldshell, and other manufacturers is being deployed continuously. Network difficulty will increase significantly over the next 12–24 months. Miners who base their ROI calculations on today's difficulty without projecting forward will be disappointed by real-world returns.
Confusing ALPH With Other Blake3 Projects
Blake3 is a general-purpose hash function that other projects may also use. Always confirm you are purchasing an ASIC specifically designed and tested for Alephium's implementation of Blake3 PoW. Generic "Blake3 miners" from unverified manufacturers may produce far lower real-world ALPH hashrates than advertised.
Ignoring the Emission Decay
ALPH's block reward is not fixed — it decreases continuously as more ALPH enters circulation. The decay is slow but real. Miners who model returns using today's block reward figure for the entire hardware lifespan will overestimate long-term earnings. Use an Alephium-specific mining calculator that accounts for emission decay.
Overlooking the PoLW Mechanism
Proof-of-Less-Work is a unique Alephium protocol feature that activates at high network hashrate. When active, it changes the economics of mining by allowing ALPH burning as an alternative to pure hashrate competition. Monitor Alephium's official documentation and community channels so you understand how PoLW affects your operation when it activates.
Skipping Firmware Updates
The ALPH ASIC ecosystem is young and manufacturers release frequent firmware updates that can significantly improve hashrate stability, efficiency, and pool compatibility. Check iPollo and Goldshell official channels regularly and apply updates promptly — outdated firmware on a young platform can leave real performance on the table.
