Information
Profit Information
The Goldshell AL Box 2 (720Gh/s) is currently mining $-0.47 profit a day. The calculations is based on $0.22 income per day from which we deducted $0.69 electricity costs. This means the AL Box 2 is able to generate up to $6.62 income per month. After you would deduct the electricity price of $20.74 you will have an estimated profit of $-14.12 per month.
Hint: With our Hosting Plans you will only pay around 0.08 USD per kWh.
If the BTC price reaches $159684 you would earn estimated $-0.36 per day.

More Information
The Goldshell AL Box 2 incorporates advanced cooling solutions, utilizing a dual-fan system with optimized airflow dynamics to maintain stable performance under continuous operation. Unlike its predecessor, this model features an improved power efficiency ratio, reducing overall energy costs for miners. The firmware includes an enhanced auto-tuning function, dynamically adjusting performance to maintain optimal hashing rates in fluctuating conditions. Additionally, Goldshell has integrated a refined noise-reduction design, making it one of the quieter compact ASIC miners on the market. The AL Box 2 also supports remote monitoring via Goldshell’s dedicated mining software, allowing users to oversee operations from any location.
Algorithm Information: Blake3
Alephium’s implementation of Blake3 extends well beyond simple hashing by incorporating a finely tuned parallel tree structure that maximizes throughput. The protocol’s consensus layer, known as BlockFlow, relies on a dynamic scheduling of micro-blocks to reduce network congestion. Sharding is achieved by distributing the UTXO set across multiple segments, allowing each shard to operate semi-independently for improved scalability. This architectural approach not only boosts transaction throughput but also mitigates bottlenecks that can plague more traditional PoW blockchains. Alephium’s nodes apply a weighted mechanism to prioritize blocks, ensuring consistent validation even under high network load. Blake3’s internal design, which separates chaining and compression functions, enhances mining consistency across GPUs, FPGAs, and ASICs alike. Its stateful parallelization model enables hardware to utilize multiple threads efficiently without sacrificing security. Because of this efficiency, enthusiasts and large-scale operators alike can optimize their setups and then verify prospective returns using our crypto miner profit calculator for the algo. Transaction signatures leverage Blake3 for compact, high-speed verification, a boon for validators handling large volumes of requests. All these elements coalesce, making Alephium a standout project that merges innovative consensus with next-generation cryptographic hashing.
