Block Announces Open-Source Bitcoin Mining Chip, Proto

Jack Dorsey, CEO of Block Inc., announced during a recent earnings call that the company plans to launch its open-source Bitcoin mining chip, Proto, in the second half of 2025.

Aiming to decentralize Bitcoin mining, Block’s Proto represents a strategic move into hardware manufacturing. The company focuses on U.S. production to mitigate geopolitical risks.

Block’s planned launch of the Proto mining chip marks a notable shift towards developing Bitcoin mining hardware in the United States. Jack Dorsey, a prominent Bitcoin advocate, emphasized the importance of collaboration with U.S. vendors and manufacturers. Building in the U.S. shows commitment to supply chain resilience.

The move towards in-house hardware development promises to impact the cryptocurrency mining market by providing alternatives to overseas technologies. “The Bitcoin hardware supply industry represents a significant revenue opportunity, estimated at $3-6 billion annually,” said Jack Dorsey, CEO of Block Inc. Dorsey confirmed Block’s potential to generate significant revenue by tapping into a $3-6 billion annual market.

The push for U.S.-based production addresses concerns over global supply chains and tariffs, reinforcing Block’s strategy for vertical integration. Dorsey expressed confidence in handling these challenges effectively through domestic partnerships.

Block’s entry reflects a broader trend of decentralized mining initiatives bolstering the Bitcoin network’s resilience. The company’s strategic direction supports smaller miners with open-source, flexible solutions.

Block’s Proto is poised to not only benefit the market financially but also enhance technological innovations in mining efficiency. This project could alter the landscape for Bitcoin miners, encouraging more decentralized and secure practices.
