The PIC Microcontroller on Antminer Hashboards: What It Does, How It Fails, and Why the S21 Has None
Ask why a hashboard reports zero chips and most troubleshooting guides jump straight to the ASICs. But on S19-generation boards there’s a 14-pin chip the…
Inside the Zynq FPGA: How an Antminer Control Board Talks to Its Hashboards
Open up any S9-through-S19-era Antminer control board and the biggest chip on it isn’t just a CPU — it’s a Xilinx Zynq, a hybrid part…
GPUs Are the New ASICs: Why AI Compute Will Decentralize Like Bitcoin Mining
AI compute is running the same concentrate-burn-distribute cycle as Bitcoin mining. GPUs go obsolete like ASICs, over-leveraged operators get burned, and the compute trickles down to the edge — ending in sovereign home mining and home AI inference.
Poolin’s Bankruptcy and the End of Mining as a Business
Poolin, once Bitcoin’s largest mining pool, filed Chapter 11 owing $163.7M in frozen IOUs to 11,700 customers. Why mining as a standalone business failed — and why dual-purpose mining is the decentralized future.

When someone shares a Meshtastic channel, they send you a link like https://meshtastic.org/e/#<data> — or the QR code that encodes the same thing. That link…
Bitcoin Core RPC Reference for Miners and Node Operators
When you run your own Bitcoin node — the foundation of solo mining and of not trusting anyone else’s copy of the ledger — you…
Antminer Hashboard EEPROM Reference: Parser Families, Layout, and Why Boards Aren’t Interchangeable
Every Antminer hashboard carries a small I²C EEPROM that answers one question for the control board: which board is this, and how was it tuned?…
Antminer NAND Flash: Boot Chain, Corruption Symptoms, and Recovery
When an Antminer refuses to boot — no web interface, no hashing, sometimes not even a network light — the diagnosis often ends at two…
The Definitive Bitaxe Overclocking Manual: Every Model, Every Setting, Maximum Hashrate
Solo mining is a numbers game. Your Bitaxe is hashing against the entire Bitcoin network — roughly 800+ EH/s of combined computational power.
Open-Source Bitcoin Miners Comparison 2026: Bitaxe, NerdAxe, NerdQAxe & More
The entire history of Bitcoin mining hardware has been a story of centralization. A handful of manufacturers, behind closed doors, designing chips and machines that only they control.
Pool Mining vs Solo Mining: The Complete Decision Guide 2026
Every Bitcoin miner faces a fundamental decision before their first hash is computed: pool mining or solo mining? This choice shapes your economics, your privacy, your relationship with the…
Bitcoin Space Heater vs Electric Heater: The Complete 5-Year Cost Comparison
An illustrative equal-heat comparison: 3,731.2 kWh per heater per season, explicit CAD cost inputs and variable mining receipts. Payback is not guaranteed.
Micro-Hydro Bitcoin Mining on a Homestead: 24/7 Baseload, Done Right
Of every renewable resource a homesteader can tap, running water is the one that behaves most like the grid. Solar quits at sundown. Wind comes…
Wind Turbine Home Bitcoin Mining: Sizing, Math & the Honest Limits
Wind gets pitched as the obvious next step after solar panels: free fuel, a tower in the back forty, and an ASIC humming through the…
Bitcoin Mining Legality Explained: Energy, Tax, and the Global Spectrum
Is Bitcoin mining legal? In most countries the act is legal – what is regulated is grid power and tax. Read the global spectrum and assess your own jurisdiction.
