Braiins OS 26.09.1 fixes a T5 sensor fault that paused Antminer S19 and S21 mining
Braiins released OS 26.09.1 for Antminer S19 and S21 machines after some miners upgraded to 26.09 encountered T5 temperature-sensor errors and stopped hashing for 60 seconds. The patch is narrow, but operators should still stage it, verify compatibility and compare pool-side results.

K1Pool and GMiner release SHA-256 ASIC firmware 1.30 with hot-chip frequency control
K1Pool lists GMiner firmware 1.30 as the latest release. It can automatically lower frequency on hot BM1368 chips, expands chip and hardware-error visibility, adds temperature sorting and moves less-used controls into advanced panels. Operators should test claims on their own hardware.
White House ratepayer pledge lists Bitdeer and sets five rules for data-centre power costs
Bitdeer appears among data-centre signatories to the White House Ratepayer Protection Pledge. The framework says large facilities should procure added supply, pay delivery upgrades and special rates, invest locally and support resilience. It is a public commitment, not a substitute for tariffs or permits.

Bitdeer reports 288.1 BTC mined, 288.4 BTC sold and zero pure holdings
Bitdeer’s weekly update for the period ending September 25 lists 288.1 BTC produced, 288.4 BTC sold and no net addition to its own Bitcoin balance. The figures show an operating and treasury choice, while sale proceeds, costs and the 0.3 BTC reconciliation remain undisclosed.
Bitcoin difficulty holds at a record 132.76T after a 4.16% retarget
Bitcoin mining difficulty reached 132.76 trillion at block 967,680 on September 19 and remained there on September 26. The higher target preserves the block schedule but reduces expected BTC per terahash until the next retarget, making electricity cost and measured efficiency more important.
Open-source audit finds a fixed hashrate offset in Bitfortun BS-1 firmware
A public-code review found Bitfortun BS-1 display paths adding 400 GH/s to measured hashrate and a separate 0.4 TH/s offset in one-minute history. The main API value was reportedly unchanged, so owners can compare pool-side and API measurements with the screen.
FutureBit HashFly makes a simulated fruit-fly brain test Bitcoin hashes in a browser
FutureBit presented HashFly, a browser demonstration that maps a fruit-fly connectome simulation to simplified double-SHA-256 checks. It is an experimental visualization, not an organic ASIC replacement, and its claimed 1 W/TH potential has not been measured on working biological hardware.
Starcloud says its second spacecraft will carry Bitcoin mining ASICs later in 2026
Starcloud’s CEO says the company intends to operate Bitcoin ASICs aboard its second spacecraft. The plan has no disclosed miner model, hashrate, power budget, launch date or pool architecture, and the official Starcloud-2 project page cited by the report did not mention Bitcoin mining.
Energy Economics study models a Bitcoin “productivity trap” for efficiency gains
An open-access Energy Economics paper argues that more efficient mining hardware can expand equilibrium resource use without increasing Bitcoin output. Its model also finds that surplus renewables may cut emissions while increasing hardware turnover, and evaluates a global Pigouvian tax as a policy response.
