Goldshell AL Box 2 (720Gh/s)

The Bitmain Antminer S21 PRO is a purpose-built Bitcoin workhorse: 234 TH/s of raw hashing power paired with a measured power draw of 3510 W, yielding roughly 15 W per TH - a clear statement of scale and intent for serious miners and large farms; it balances peak throughput with the kind of predictable energy profile operators need to model profitability, and our crypto-miner profit calculator translates that predictability into actionable projections (daily, monthly, yearly) while factoring in electricity rates, pool fees, network difficulty and real-time mining conditions so you can see how changes in hash price, difficulty or power cost alter returns; for quieter, space-constrained or residential deployments the Goldshell AL Box 2 offers a complementary proposition: an ASIC tuned to the Blake3 algorithm for Alephium (ALPH), delivering 720 GH/s at just 360 W (about 0.5 W per GH), in a compact 198 x 150 x 96 mm chassis weighing roughly 2.2 kg, operating at a low 35 dB noise signature and designed to run stably between 5–35 °C and 5–65% humidity, with two fans and Ethernet connectivity to maintain temperatures and uptime - in practice this means the S21 PRO is the efficient, high-throughput anchor for commercial farms while the AL Box 2 is the low-noise, energy-sparse choice for home or office miners, and the combined data points (hashrate, wattage, environmental limits, noise and connectivity) feed directly into profitability models so you can architect deployment, cooling and electrical provisioning with precision rather than guesswork.

The Goldshell AL Box 2 feels like a small mechanical organism whose cooled lungs breathe through two fans and optimized airflow. It is an ASIC built for the Blake3 algorithm and it mines Alephium (ALPH). The unit pushes 720 GH/s while consuming 360 W, roughly 0.5 W per GH. Dual fans and tuned airflow keep temperatures stable during continuous operation. Firmware includes an auto-tuning mode that adjusts performance in real time to preserve optimal hashing. A refined noise-reduction design keeps acoustic output near 35 dB so the miner blends into a home or office. The compact case measures 198 x 150 x 96 mm and weighs about 2.2 kg so it fits on a shelf or desk. Operational limits span 5–35 °C with 5–65% relative humidity for reliable duty. An Ethernet interface provides steady connectivity and the device supports Goldshell’s remote monitoring software. That software reports hash rates, temperatures and uptime and lets you change pool settings and monitor health from anywhere. The AL Box 2’s efficient power draw and quiet operation make it practical for discreet residential mining. Deploying one requires a compatible PSU, a stable network connection and a location with basic airflow for best longevity.

Blake3 je kryptografická hashovací funkce, která slouží jako základna pro Alephium důkaz-práce konsenzuální mechanismus. Tento algoritmus zpracovává vstupní data libovolné délky a produkuje pevnou hash hodnotu, čímž zajišťuje bezpečnost a integritu v procesu těžby.
