Jack Dorsey's Block rolled out its Proto Rig mining hardware and free Proto Fleet management software today. The technology company hopes to extend mining rig lifespans and make large-scale operations easier to run.

- Open-Source Management: Proto Fleet software was released for free, giving miners an open-source platform to monitor, troubleshoot, and optimize operations at scale.
- Decentralization Push: The Proto line is part of Block’s effort to diversify mining hardware suppliers and make advanced equipment more accessible.
- Chip Partnership: This release builds on Block’s earlier mining chip supply deal with Core Scientific, aimed at improving miner access to high-performance chips.
Bankless Take:
Although Block expresses optimism that its Proto Rig will enjoy a longer lifespans than alternative hardware options, crypto mining is an extremely competitive industry that naturally centralizes control and rewards among top performers. It will interesting to see if Proto Rig actually lives up to its promises and whether future upgrades are cost-effective for miners.
