IceRiver AL2 Lite (2Th)

2 TH/s Blake3 at 500W and 250 J/TH efficiency. ±10 percent hashrate and ±10 percent power tolerance per IceRiver official documentation. Released October 2024. The home tier of IceRiver's AL family lineup, sitting between the AL0 (400 GH/s) and AL3 (15 TH/s).

Substantially more efficient per gigahash. The AL2 Lite at 250 J/TH versus Goldshell AL Box 3 at 480 J/TH and AL Box 2 at 500 J/GH. The AL2 Lite delivers nearly 2x better watts per gigahash than any AL Box family unit. At equivalent hashrate output: 1 AL2 Lite at 2 TH and 500W versus 1.6 AL Box 3 units at 960W combined for equivalent total output. The AL2 Lite is the efficiency leader in the home tier Alephium ASIC market by a substantial margin.

Different deployment tiers. The AL2 Lite at 2 TH and 500W is home tier hardware deployable in residential settings with universal voltage and 45 dB noise. The AL3 at 15 TH and 3,500W is industrial tier hardware requiring dedicated mining facility deployment, 75 dB noise, and industrial electrical service. The AL3 delivers 7.5x more hashrate per chassis but requires substantially more deployment infrastructure. For home or small office deployment, the AL2 Lite is the practical choice. For industrial deployment, the AL3 delivers better total economics per unit.

Alephium is a Layer 1 sharded blockchain launched in late 2021 using Proof of Less Work (PoLW) consensus paired with the Blake3 algorithm. The network uses BlockFlow consensus and UTXO-based sharding for parallel transaction processing while maintaining decentralization. Mining Alephium means computing Blake3 cryptographic hashes for the network in exchange for ALPH token rewards. Operators mine Alephium for direct ALPH accumulation, exposure to the sharded blockchain and PoLW consensus thesis, and diversification beyond established proof of work chains.

Honestly, no, at typical retail electricity rates. MillionMiner calculator at $0.08 per kWh: -$0.65 daily loss. At $0.05 per kWh: -$0.29 loss. At $0.03 per kWh: -$0.05 loss, near break even. At $0.02 per kWh: +$0.07 daily profit. Break even at approximately $0.026 per kWh. The AL2 Lite is the closest to profitability among home tier Alephium hardware at current network conditions, but still requires industrial hosting electricity rates for positive economics. Best approached as ALPH accumulation hardware for long term holders.

Three buyer profiles still make sense today. First: ALPH accumulators positioning for long term Alephium network growth, treating the hardware as the most efficient ALPH acquisition vehicle in the home tier. Second: home miners wanting maximum Alephium output within residential deployment constraints, where the AL2 Lite's efficiency advantage means lower daily loss than Goldshell alternatives. Third: existing Alephium miners adding density to fleets where the AL2 Lite's efficiency compounds across units. For buyers seeking immediate profit at current network conditions, the AL2 Lite is not the right purchase.

100 to 240V universal AC input via the included PSU. At 110V draws approximately 4.5 amps continuous. At 220V approximately 2.3 amps. Compatible with any standard residential or commercial outlet worldwide. No dedicated 220V circuits or special wiring required. The 500W power draw fits comfortably within any standard 15A residential circuit.

45 dB from dual cooling fans at peak operation per IceRiver and most distributor sources. Comparable to a quiet refrigerator or normal conversation level. Suitable for deployment in home offices, utility rooms, basements, garages, or small commercial offices without sound isolation requirements. Substantially quieter than industrial Bitcoin mining hardware (typically 75 dB). Quiet enough for residential deployment though not bedroom-adjacent without consideration.

198 x 201 x 110 mm miner dimensions at 5 kg net weight per IceRiver and most distributor sources. Compact desktop format larger than IceRiver's AL0 entry tier but smaller than industrial Alephium hardware. Fits on any shelf, desk, or small mining rack. Single hand placement and movement.

0 to 40 degrees Celsius operating range at 10 to 90 percent humidity tolerance per IceRiver and most distributor documentation. The 500W power draw produces approximately 1,706 BTU per hour of heat output, easily absorbed by a typical residential room. For deployment in hot climates, ambient cooling should hold intake air below 35 degrees Celsius at peak load to maintain consistent hashrate.

Alephium (ALPH) primarily via the Blake3 algorithm. Other Blake3-based cryptocurrencies could theoretically be mined if pool support exists, though Alephium is by far the dominant Blake3 mining target. Cannot mine Bitcoin, Litecoin, Kaspa, Aleo, Monero, or any algorithm outside Blake3. The algorithm specificity is the trade off for the AL2 Lite's efficiency advantage over GPU rigs.

Yes. The AL2 Lite ships with an integrated PSU sized for the 500W rated load, along with power cables and quick start guide. Box contents per MillionMiner: AL2 Lite unit, PSU, power cables, and quick start guide. Contents may vary by batch with exact items in order confirmation.

Standard IceRiver setup. Step one: connect the included PSU to the miner and plug into any standard 100 to 240V wall outlet. Step two: connect Ethernet cable to the router or network switch. Step three: find the miner IP through router DHCP or network IP scanner. Step four: open the IceRiver web interface in a browser, configure Alephium pool URL and ALPH wallet address, change default credentials. Step five: verify hashrate stabilizes at approximately 2 TH/s within 10 to 15 minutes.

Major Alephium mining pools accept AL2 Lite hashrate including HumPool, Lolminer Pool, Herominers, IceRiverMining, K1Pool, F2Pool, NiceHash, and Kryptex. Pool fees typically 0.5 to 2 percent. Standard Stratum protocol with no hardware restrictions on pool selection. The AL2 Lite's 2 TH hashrate reaches pool minimum payout thresholds substantially faster than smaller home tier hardware.

180-day IceRiver factory warranty starting from shipping confirmation date. Covers manufacturing defects and hardware failures under normal operating conditions. Tampering with warranty seal, use of incompatible PSU, exceeding rated voltage input, or physical damage from shipping voids coverage. Warranty claims processed through MillionMiner support with direct IceRiver channel escalation. Extended 7-year warranty available through IceRiver's hosting program.

Standard residential ASIC maintenance. Quarterly dust cleaning of the dual fan intakes prevents thermal throttling and premature fan bearing wear. Annual fan bearing inspection with replacement if bearing noise develops. Monitor hashrate continuously through the IceRiver web interface. Approximately 18 months of field reliability data as of April 2026 with no known systemic reliability issues.

Yes. MillionMiner hosting accepts AL2 Lite units. At industrial hosting electricity rates ($0.04 per kWh and below), the AL2 Lite crosses into profitable territory. For self deployment at retail rates, the AL2 Lite remains a daily loss but the smallest loss among home tier Alephium hardware. Hosting becomes the path to profitable operation if the buyer wants immediate positive economics rather than long term ALPH accumulation. Contact MillionMiner for current hosting rates.

Decisively better. RTX 4090 produces approximately 7 to 9 GH/s at 350W (39 to 50 J/GH efficiency). The AL2 Lite at 2,000 GH/s and 500W delivers 0.25 J/GH, approximately 156 to 200 times better efficiency per gigahash. Matching the AL2 Lite's 2 TH output via GPUs would require approximately 220 to 290 GPUs at 77 to 101 kilowatts combined power. Dedicated ASIC hardware is the only economically viable path for serious Alephium mining.

Buy the AL2 Lite if you want the most efficient home tier Alephium ASIC available, you are positioning for long term ALPH accumulation believing in Alephium network growth, you are comparing IceRiver versus Goldshell home tier hardware (the AL2 Lite wins on efficiency math), or you have access to industrial hosting electricity for profitable operation. Avoid the AL2 Lite if you need immediate profitability at retail electricity rates, you have no Alephium investment thesis beyond mining, or you are uncertain about Alephium's long term network viability since the hardware is locked to Blake3.
