Proto Rig: How Block’s New Mining System Could Transform Bitcoin Mining

Block Inc. (Jack Dorsey’s team) has unveiled Proto Rig, a Bitcoin mining system designed by engineers with backgrounds at Apple, Tesla, and Google. With a 3nm custom ASIC, modular design, and open-source fleet software, Proto is pitched as a complete rethink of Bitcoin mining hardware.In this episode of the Compass Mining Podcast, we’re joined by Tatum Cave, Compass Mining’s large-scale project lead and safety overseer at our Denver Service Center. With years of experience repairing, deploying, and stress-testing ASICs, Tatum shares his honest perspective on what Proto Rig could mean for miners in the field.What you’ll learn in this episode:- Proto Rig’s bold design promises: modular upgrades, easier repairs, higher density, and longer lifespans- Why competition beyond Bitmain and MicroBT is a big deal- Field concerns: durability, hot-swapping, integration with existing fleets- Efficiency claims vs. real-world expectations (14.1 J/TH vs closer to 20 J/TH)- The potential of Made in America mining hardware through TSMC’s Arizona fab- Why pricing, timelines, and real-world stress tests still leave big questionsThe bottom line: If Proto delivers even part of its vision, it could reshape Bitcoin mining infrastructure. But as Tatum makes clear, miners will want to test it in the field before making big commitments.💻 Follow Compass Mining on social media:🔗 X - https://x.com/compass_mining 🔗 Linkedin - https://www.linkedin.com/company/compassmining/?viewAsMember=true 🔗 Instagram - https://www.instagram.com/realcompassmining/ 🔗 Tiktok - https://www.tiktok.com/@compassmining
