Jack Dorsey’s fintech company, Block, is shaking things up in the Bitcoin mining world with its new product, the Proto Rig. No, it’s not a shiny new toy for tech geeks; it’s a powerful mining machine designed actually to last. While most mining rigs only last three to five years, this bad boy is built to run for 10 years. Yes, you heard that right, 10 years.
But here’s the real catch: the Proto Rig comes with swappable parts, so instead of throwing away the whole rig when something breaks, miners can just upgrade individual parts, like hashboards. This nifty design will save miners anywhere from 15-20% each time they upgrade.
A Lifesaver for Miners
Let’s face it, mining equipment is expensive. Machines break down, repairs take forever, and upgrading is a pain. It’s a huge problem that eats into profits, especially as mining gets more difficult. As Block’s hardware lead, Thomas Templeton, puts it:
"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 the Proto Rig, Block’s on a mission to fix that, and maybe even contribute to decentralizing hardware in the process.
Today marks the end of rip and replace Bitcoin mining. Proto Rig—the first miner built to be infrastructure.

Why Now? The Mining Landscape
The timing couldn’t be better for the Proto Rig. The cost of mining has been soaring, and the rewards have gotten slimmer since last year’s halving event. Miners now only earn 3.125 BTC instead of 6.25 BTC for verifying transactions, and honestly, that’s not enough to keep up with rising expenses.
In fact, industrial miners are running full warehouses of rigs just to keep up, so anything that can lower costs is a win. Companies like MARA Holdings, the world’s largest BTC miner, have reported impressive gains, but those are mostly thanks to the rising price of Bitcoin. The challenges miners face aren't going anywhere soon—some companies have even shifted gears to AI or pivoted to become Ethereum treasuries.
Dorsey’s Vision
Here’s the real twist: while most mining rigs are made in China, Dorsey has said he wants to change that. He’s pushing for the manufacturing of these rigs to happen in the U.S., a bold move that could shake up the mining industry even further. Plus, it’s a nice touch for all the patriotic Bitcoin fans out there.
More Bitcoin Products from Block
Block’s not stopping with Proto Rig. Its other ventures, like Square and Cash App, have also jumped on the Bitcoin train. Square’s payment terminals now let merchants accept Bitcoin payments, although it’s still rolling out globally. Oh, and don’t forget about the Bitkey hardware wallet, a handy little gadget for Bitcoin storage.
But back to the stock market. Block’s stock was down about 1% on Thursday, according to Yahoo Finance, but it’s still up 10% in the last month. For the year, it’s down over 12%, but with its S&P 500 inclusion in July, things are looking hopeful.
Bitcoin’s Rollercoaster Ride
On a final note, Bitcoin was recently trading around $119,118, down nearly 3% after hitting an all-time high of over $124,000. But let’s not forget, Bitcoin is still up more than 25% this year, which is pretty wild. Dorsey, who left Twitter to go all-in on payments and Bitcoin, continues to dream of Bitcoin becoming the global currency, and, honestly, I wouldn’t bet against him. After all, he’s the guy who calls Nakamoto’s Bitcoin white paper “poetry.”
