方尖碑网页现在开放接受提前预定。价格是一台$2,499 美金 (或同等价值的BTC, ±5%). 截止至2017年八月，大概卖出了1500台方尖碑矿机。 第一批方尖碑矿机的最高上限是4000台。
Pre-ordering a first generation Obelisk will ensure six weeks of mining without competition from future Obelisk batches in order to help guarantee return on investment - future batches will not ship for at least six weeks from the first batch, providing a period of exclusive mining.
Pre-orders will also receive a $250 coupon towards the purchase of an Obelisk in a future batch.
Specifications are still somewhat vague as the hardware is still being designed, but the following specifications have been provided:
|Chip||Full Custom 28NM ASIC|
|Hashrate||800 GH/s or greater|
|Power Consumption||500W or less|
|Noise||65 DBA or less|
|Weight||20 pounds or less|
At the maximum of 4,000 Obelisks sold, expected Siacoin yields are 150,000 SC/month. At a price of $0.01/SC, a return on investment would be realized within two months. If fewer than 4,000 Obelisks are sold, return on investment would be realized more quickly.
Once released, the Obelisk will quickly make GPU mining of Siacoins obsolete because it will no longer be cost-effective to mine using a GPU. One Obelisk will have the hashing power of approximately 100 GPUs. Block difficulty is expected to increase significantly once Obelisks are released and added to the network.
