Obelisk is a new project the developers of Sia have been teasing.
It has been revealed that the Obelisk SC1 is a Siacoin mining ASIC (application-specific integrated circuit).
More information about Obelisk will be gradually released during the week of 19 to the 23rd of June. Lead developer David has promised that by the end of Friday everyone will know what Obelisk is all about.
All currently available information has been leaked through the #obelisk channel in the Sia Slack community (see the sidebar for a link to join the Slack).
Lead developer David Vorick posted a strange logo in the Slack community, with the filename “obeliskComingSoon.png”.
A larger image was posted by Zach Herbert in the #announcements channel with the title “Coming soon. #obelisk” (this is the image at the top of this article), along with a link to a new Slack channel #obelisk. David then proceeded to release some subtle hints in that channel, which are logged below under Hints.
Zach also changed his Slack status to the Obelisk emoji with the message “Hello from Sia/Obelisk HQ in Boston!”, indicating that Obelisk is the second product the team is developing.
Another interesting detail is that the channel topic for the #obelisk channel is a link to the website obelisk.tech which, at the time of writing, is just a blank page.
Taek42 talks about Obelisk on reddit:
We are trying something new with the way we roll out Obelisk, and we'll know based on the reaction when the full reveal happens whether it was a good way to launch Obelisk or not.
I'm happy to reassure everyone who is concerned that Obelisk is not a troll, and that it's also much more substantial than a weekend project. I can't promise that you will like it, but it is something big and substantial, and it is good for Sia and an important step for any Proof-of-Work cryptocurrency.
At 23:26 UTC (technically still the 19th), taek shared another picture in the #obelisk channel, showing some kind of integrated processing chip. This picture was immediately deleted from the logs and was later discovered (11:28 UTC) by Slack user “softlaunch” by looking in taek's upload history:
At 14:32 UTC a tweet is posted on the SiaTechHQ twitter feed using the same image with the following caption:
