August 14, 2025 at 10:45 AM EDT

Block, Inc. (NYSE: XYZ) today unveiled Proto Rig, a first-of-its-kind modular bitcoin mining system, and Proto Fleet, a free and open-source fleet management software. The announcement, made during an event held at Proto customer Core Scientific's facility in Dalton, GA, where Proto Rigs are mining as part of their fleet, represents a significant step toward decentralizing bitcoin mining hardware, opening access to more builders, and increasing network resiliency. These mark the first two end-to-end releases by Proto, Block’s suite of bitcoin mining products and services, following its initial chip sale to Core Scientific.

Proto Rig, modular bitcoin mining system by Block, Inc.

Proto Rig: Durable, repairable, upgradeable infrastructure

Moving away from disposable hardware models, Proto Rig is designed to be infrastructure—a paradigm shift that solves many existing pain points for miners and signals the company’s long-term commitment to the industry.

Proto Rig’s modular design lets operators upgrade individual hashboards without replacing entire units, transforming what has historically been a 3-5 year disposable asset into a 10-year infrastructure investment, reducing costs by 15-20% each upgrade cycle. It also allows for easy, in-place, tool-free repair, turning a process that can take hours, days, or weeks into one that takes seconds, saving miners valuable time and resources.

“Mining hardware hasn’t really changed in years,” said Thomas Templeton, Hardware Lead at Block. “Machines break often, are hard to repair, expensive and time-consuming to upgrade, and don’t make the most efficient use of power or space. With Rig, we set out to change all of that–and contribute to hardware decentralization in the process.”

With unmatched power density and maximum miner uptime, Proto Rig delivers 1.5 times the power per foot of rack space compared to traditional mining hardware. Designed to be compatible with modern and legacy infrastructure, Proto Rig gives mining operators the power to maximize efficiency in their existing facilities without requiring extensive retrofitting, addressing long-standing challenges in power utilization and lifecycle management.

Proto Fleet: Comprehensive, open source, and free

Alongside Proto Rig, Block also announced Proto Fleet, comprehensive, open-source fleet management software that brings together power-scaling, monitoring, diagnostics, and maintenance tools in a single, intuitive platform.

“Mining hasn’t really caught up with advances in software more broadly,” said Templeton. “We saw an opportunity to make mining software something modern that improves operational efficiency instead of unnecessarily complicating things.”

Proto Fleet brings together many functionalities that have historically required their own, individual pieces of software to manage, helping miners streamline operations, maximize uptime, and minimize time spent troubleshooting. A big part of Proto’s effort to decentralize mining, Proto Fleet will be available for anyone to use, at no cost, giving mining operators of all sizes access to powerful fleet management software. All of these advancements together—on-rack, tool-free repairability, high-quality components, swappable hashboards, and backwards compatibility—mean more uptime across install, repairs, upgrades, and ultimately the life of the machine.

The reveal of both products builds on Block's long track record of building transformational technology and rounds out the company’s broader commitment to bitcoin across Square, Cash App, Bitkey, and Spiral.
