Alephium Mining Guide 2026: How to Mine ALPH (Blake3)

Alephium (ALPH) is one of the most technically ambitious proof-of-work cryptocurrencies in active development. Its BlockFlow sharded UTXO model and Proof of Less Work (PoLW) consensus mechanism differentiate it sharply from both Bitcoin clones and smart contract platforms. For miners, it offers a currently minable network with a growing ecosystem — and, as of 2026, a transitional period where both GPU and ASIC hardware are viable depending on your cost structure. This guide walks through everything you need to start mining ALPH.

What Makes Alephium Different?

Alephium solves two long-standing problems in blockchain design simultaneously:

• Scalability via sharding: Alephium splits its state into 16 groups (shards), each processing its own blocks. This allows the network to process many more transactions per second than a single-chain design — potentially 10,000+ TPS — while retaining full PoW security.
• Energy efficiency via Proof of Less Work (PoLW): When the network reaches sufficient hashrate, PoLW allows miners to "burn" ALPH to reduce the required proof-of-work difficulty, effectively recycling a portion of energy cost into network economic activity rather than pure heat.

The mining algorithm is Blake3 — a modern, extremely fast cryptographic hash function that is both ASIC-friendly and well-suited to parallel GPU execution. It differs from the older Blake2 used by some other coins and is significantly faster in hardware.

Hardware Options in 2026

ASICs

Blake3 ASICs have been available since 2024. In 2026, the main options are:

• Bitmain Antminer AL1 Pro — The leading Blake3 ASIC. ~15 TH/s (ALPH-specific terahash) at ~3,500W. Dramatically outperforms GPUs in J/TH. Best choice if you can secure one at a reasonable acquisition cost and have access to cheap electricity.
• Goldshell AL-BOX — Compact, lower-hashrate unit aimed at home miners. ~2 TH/s at ~600W. Good entry-level option with lower noise output than rack-mount ASICs.

GPUs

GPUs remain viable for Blake3 at low electricity costs, though efficiency is significantly worse than ASICs. Representative hashrates at stock settings:

• NVIDIA RTX 4090 — ~3.5 GH/s at ~350W. Top GPU option; very high acquisition cost limits ROI at current ALPH prices.
• NVIDIA RTX 3080 Ti — ~2.1 GH/s at ~330W. Good secondary-market value; widely available.
• AMD RX 7900 XTX — ~2.6 GH/s at ~300W. Competitive with Nvidia on Blake3; good efficiency ratio.
• NVIDIA RTX 3060 Ti — ~1.2 GH/s at ~165W. Budget-friendly; excellent J/GH for a mid-range card.

For GPU mining, use lolMiner (NVIDIA + AMD, 1% dev fee) or the official Alephium GPU Miner (open source, no dev fee). Both handle multi-shard routing automatically.

Step-by-Step: Start Mining Alephium

Step 1 — Set Up an Alephium Wallet

Download the official Alephium Desktop Wallet from github.com/alephium/alephium-frontend. Create a new wallet and save your 24-word mnemonic phrase securely offline. Your ALPH address starts with 1 followed by a base58 string. You'll enter this address in your pool configuration.

Alternatively, the Alephium Extension Wallet (Chrome/Firefox) provides a browser-based option. For large balances, use the desktop wallet for better security.

Step 2 — Choose a Mining Pool

Recommended Alephium mining pools:

• WoolyPooly (alph.woolypooly.com:3106) — PPLNS, 0.5% fee, beginner-friendly dashboard, strong ALPH support
• HeroMiners (alph.herominers.com:1199) — PPLNS, 0.9% fee, good statistics and SOLO option
• K1Pool — Low fee, dedicated ALPH support, growing hashrate
• 2Miners — PPLNS and SOLO modes, 1% fee, established infrastructure

Step 3 — Configure Your Miner

For GPU miners (lolMiner example):

lolMiner --algo ALPH --pool stratum+tcp://alph.woolypooly.com:3106 --user YOUR_ALPH_ADDRESS.worker1

For ASIC miners: Access the web interface (typically 192.168.x.x), navigate to miner settings, and enter:

• Pool URL: your pool's stratum address
• Worker: your ALPH wallet address (with optional .workername suffix)
• Password: x (or leave blank)

Step 4 — Monitor and Optimise

After 5–10 minutes your pool dashboard will show your miner as active. Key metrics to watch:

• Reported hashrate vs. rated hashrate: Should be within 5% of spec. Larger discrepancies suggest connectivity issues or overheating.
• Share rate: Stale shares above 2% indicate network latency — try a geographically closer pool server.
• Temperature: ASICs should run below 80°C chip temperature; GPUs below 75°C for sustained operation.

Alephium Network Fundamentals

Key statistics as of June 2026:

• Algorithm: Blake3
• Shards: 16 groups, each with ~64-second block time (~4 blocks/second network-wide)
• Block reward: ~1.5–2 ALPH per block (smoothly declining emission)
• Total supply cap: 1 billion ALPH (long-term)
• Mainnet launch: November 2021
• Smart contracts: Alephium supports smart contracts via its Alphred VM — a stateful UTXO model distinct from Ethereum's account model

Profitability Outlook

Alephium's emission schedule means block rewards decline gradually over time, similar to Bitcoin's model but without discrete halvings. Mining profitability in 2026 is viable for efficient operators:

• GPU miners need electricity below ~$0.08/kWh to remain competitive against ASIC network participants
• ASIC miners (AL1 Pro) have a break-even threshold near $0.10–$0.12/kWh at current ALPH prices
• ALPH's DeFi ecosystem expansion and smart contract adoption are the key drivers of potential price appreciation, which would improve miner margins
