Our early decision to use SHA-1 was a balance between limitations of mobile hardware and the security landscape of the day.

Much of Skynet's core technology is actually designed for mobile platforms. Skynet essentially thinks of a desktop computer as a fancy phone with a different UI toolkit and without a cellular modem.

While switching to SHA-2 is on our to-do list, it's not as high as nailing a stellar experience for our users. Should SHA-1 erode more quickly than expected, we'll be sure to bump up the priority of that transition. We'll be sure to pivot the network before it's a real problem.
