Jack Dorsey's payments company, Block, is building a system for bitcoin miners

Jack Dorsey's payments company Block (formerly Square) is going to start mining for bitcoin.

In a string of tweets, Block's general manager for hardware, Thomas Templeton, laid out the company's plans for next steps.

Templeton says the goal is to make bitcoin mining — the process of creating new bitcoins by solving increasingly complex computational problems — more distributed and efficient in every way, "from buying, to set up, to maintenance, to mining."

The idea of making the mining process more accessible has to do with more than just creating new bitcoin, according to Templeton. Instead, he says the company sees it as a long-term need for a future that is fully decentralized and permissionless.

The project is being incubated within Block's hardware team, which is beginning to build out a core engineering team of system, ASIC, and software designers led by Afshin Rezayee.

In terms of the hardware, Dorsey previously tweeted that the company was considering a "bitcoin mining system based on custom silicon." Dorsey went on to share his thoughts on the need for more of a focus on vertical integration, as well as on silicon design, which he says is too concentrated among a few companies.

Templeton writes that Block also looking to i...
