Obelisk Obelisk was launched in June 2017, aiming to shine a light of transparency into the opaque mining ecosystem and offer a trusted alternative to the monopoly. Obelisk designs and manufactures PoW mining hardware. They currently produce ASIC miners for Siacoin and Decred, and will ultimately produce miners for most PoW cryptocurrencies – including Bitcoin. Obelisk prioritizes transparency, customer service, and good design. Based in Boston, and the hardware is manufacturered in the United States. Obelisk’s goal is to create a strong, healthy PoW ecosystem. This means open-sourcing all work, including software and hardware. This means only self-mining for testing purposes and not competing with the customers. And this means publishing content to increase transparency in a historically secretive industry.
