ExploitBench and ExploitGym: The Benchmarks Bitcoin Security Now Depends On
Two benchmarks measure whether an AI model can turn a suspected bug into a proven exploit. A joint UK-US government evaluation put Kimi K3 at 0 of 41 on arbitrary code execution against 20 of 41 for frontier models. Bitcoin’s defenders were pushed toward the wrong end of that gap.
The Bitcoin Red Team: 4,962 Findings in 27.5 Hours
Sixteen volunteers, a 171,599-line AI harness and 390 open-source Bitcoin repositories in a single sprint. What the Bitcoin Red Team did, why it was overdue, and the two honest criticisms the effort deserves.
Coldcard, BTCPay Server, Boltz: Bitcoin’s Exploit Wave and What To Do Now
Three Bitcoin infrastructure failures in eleven days: a four-year Coldcard entropy defect, an actively exploited BTCPay Server credential leak, and a swap service that shut down because it could not patch fast enough. The factual record and the actions each one demands.
3D-Printed Bitcoin Mining Parts: Free STL Files and What’s Worth Printing
There has never been a better time to own a 3D printer and a bitcoin miner at the same time. The gap between “I need…
Ducting a Mining Farm: Rack-Scale Airflow Without the Guesswork
One miner in a garage is an airflow problem you can solve with a window. Twenty miners in a converted storage room is a different…
Avalon Airflow: Canaan’s 122 mm Fan Pitch and How to Duct It
Canaan has always been the manufacturer that refuses to copy the other two. While Bitmain and MicroBT argued about 120 versus 140 mm fans, Avalon quietly…
The Intake Side: Dust Filters and Fan Swaps for ASIC Miners
Every home mining setup thread shows the same picture: a beautiful exhaust job — shroud, insulated duct, sealed window port — bolted to a miner…
ASIC Miner Silencers: How They Work and How to Choose One
Search for an ASIC miner silencer and you will find products promising to make a 75-plus-decibel machine apartment-friendly, with confidence no acoustics lab would sign.…
How to Vent a Bitcoin Miner Out a Window (Properly)
A window is the most common exit point for home-miner exhaust, and also the most commonly botched one. Cracked-open sashes with a duct wedged in…
Whatsminer Ducting: Why 120 mm Shrouds Don’t Fit and What Does
Search for a duct adapter for your miner and you will drown in Antminer gear. Dual-120 shrouds, 120 mm silencers, 120 mm filter rings — an entire…
6-Inch vs 8-Inch Duct for ASIC Miners: The Real Sizing Guide
Every ducted mining setup eventually hits the same question: 6-inch or 8-inch? Pick too small and your fans fight the duct all day. Pick too…
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.
Nostr Standardized Tags Reference: The e, p, a, d and Named Tags, by NIP
A Nostr event has three moving parts: its kind (what type of thing it is), its content (the payload), and its tags (structured metadata that…
bitcoin.conf Reference: Configuring Your Node for Sovereignty and Solo Mining
If the RPC interface is how you talk to your Bitcoin node, bitcoin.conf is how you shape it — the settings file that decides how…
Meshtastic Channel URL Reference: What a Shared Channel Link Actually Contains
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
Yes. Both devices convert 100% of consumed electricity into heat — this is dictated by the first law of thermodynamics.
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.
ASIC Operating Temperature Guide: Throttle, Shutdown & Intake Limits
What ASIC max-chip, intake, throttle and shutdown temperatures mean, how firmware throttling de-rates hashrate, how to read temp telemetry, and the intake to target.
