Block says it is building an open-source bitcoin mining system to make mining more “distributed and efficient”, after Jack Dorsey teased the idea in October
The payment services company formerly known as Square is open to building new mining computers and is hiring for a new engineering team.
Context & Ripple Effects
Block is moving from Jack Dorsey's earlier proposal to build an open-source miner with custom silicon to recruiting an engineering team and developing mining computers. The effort follows Square's solar-powered mining-facility partnership with Blockstream, placing hardware development alongside an existing mining investment.
Later coverage shows the program advanced to Block's own 3nm mining chip and a foundry design process, making this announcement the opening step in a longer push into mining infrastructure.
First-order effects
- Block shifts from evaluating a miner to staffing a team to build one, committing the company directly to bitcoin-mining hardware development.
- The open-source system is intended to make distributed participation and efficiency design goals of Block's mining product, rather than simply adding a closed mining computer.
Second-order effects
- Block's mining-facility investment with Blockstream gains a hardware-development counterpart, broadening Block's role from funding a mining site to building equipment for the sector.
- The subsequent 3nm chip program moves Block's effort into semiconductor design and a relationship with a global foundry, extending the original mining-system plan beyond software and computer assembly.
Third-order effects
- If Block continues linking mining hardware, custom chips and its existing bitcoin products, mining becomes a strategic infrastructure layer for the company rather than a standalone investment.
- Open-source mining designs would shift more of the competitive focus toward chip execution, manufacturing access and operating efficiency, even as Block seeks wider participation in mining.
The trend: Bitcoin-focused companies are expanding from financial products and mining investments into the hardware and semiconductor infrastructure behind the network.
