OBELISK GRN1

FOR MINING GRIN


TOKEN DETAILS

Grin is a private and lightweight implementation of the mimblewimble blockchain. Launched on January 15, 2019, Grin strives for scalability, openness, fair distribution, and privacy by default.

Grin's Proof-of-Work consists of two sets of algorithms, one ASIC-resistant and one ASIC-friendly. Over time, the ASIC-friendly algorithms phase in, reaching 100% of the block reward by January 2021. Grin's first ASIC-friendly algorithm is Cuckatoo31+, which should maintain dominance until approximately April 2020.

MINER DETAILS

Obelisk expects to complete our Cuckatoo31+ ASIC design by end of March 2019. We are working toward a GRN1 ship date of October 2019.

PRELIMINARY SPECIFICATIONS
Based on early designs, we estimate that the Obelisk GRN1 can reach 100 GPS at 800 W. An NVIDIA RTX 2080 Ti, by comparison, reaches approximately 2 GPS at 250 W.

Please note – these estimates are very preliminary. In March we expect to have completed full ASIC simulations, and we will be able to provide more accurate estimated specs.

SALE INFORMATION

This sale allows you to obtain an Obelisk GRN1 at a significant discount by purchasing a voucher. Each voucher costs $3,000, and is exchangeable for one GRN1 miner.

When we launch the full machine sale, expected for mid-March, we will sell GRN1 miners for $6000 each. This voucher sale allows you to obtain a miner at a 50% discount.

From the $3,000 per voucher, Obelisk will use approximately $1,000 toward chip development, electromechanical design, and chip tapeout. This $1,000 is therefore nonrefundable, as it allows us to cover non-recurring engineering costs.

In mid-March, we expect to launch the full machine sale. Alongside this launch, we will be providing updated specifications based on ASIC simulations and an updated estimated shipping date. If you are unsatisfied for any reason before the full machine sale closes, we will refund $2,000 of your voucher – no questions asked.

We are offering a maximum of 10,000 vouchers during this sale period. We are also excited to announce that we will be setting aside $100 per voucher to fund Grin development!
