The Server One is officially back in stock at solosatoshi.com. If you've been following the hardware market, you know the AI boom has been wrecking the memory supply chain. RAM and SSD prices spiked hard, and last month we ran into shortages like everyone else.

Good news is we were still able to secure inventory, so both configurations are available right now:

• 2TB SSD / 16GB RAM - powerful, private, plug and play.
• 4TB SSD / 32GB RAM - more space and headroom if you plan to run a lot of services.

If you've been on the fence about running your own node, fair warning that with AI data centers buying up memory at this pace, hardware availability and pricing are only getting less predictable. We can't promise how long this batch lasts or what the next one costs.

Happy to answer any questions!

Hey everyone,

You've probably seen the news that one of Trezor's shipping providers was breached, exposing names, shipping addresses, phone numbers, and emails for thousands of customers. This isn't a dunk on Trezor. Third-party breaches can hit anyone, and their 90-day retention policy genuinely limited the damage, but it's a good moment to remind people that the strongest protection is data that never gets collected in the first place.

A reminder of how we handle this at Solo Satoshi:

1. Alias names are fine. We don't require your legal name to place an order.

2. PO Boxes are fine. You don't need to give us (or any shipping partner) your home address.

3. Use an alias or throwaway email. Creating a new email address is free. A fresh Proton Mail email takes a couple minutes to set up.

4. Customer service only needs your order number. Not your name, not your ID, nothing else.

If your name, home address, and email are sitting in a database somewhere, they're only as safe as every vendor and shipping partner that touches them. Minimize what you hand over and there's nothing to leak.

Standard reminder that applies no matter whose hardware you use: never type your seed phrase into a website, and never share it with anyone. No legitimate company will ever ask for it. Also be careful clicking suspicious links.

Stay safe out there.

The Avalon Q is back in stock at Solo Satoshi!

• 90 TH/s at 18.6 J/TH
• Three power modes: Eco (~800W), Standard (~1,300W), Super (~1,674W)
• Runs on standard 110V household power, 220V compatible

Happy to answer any questions about power requirements, noise, or setup in the comments.

With everything going on lately around hardware wallet seed generation, a lot of people are asking the right question for the first time: where does my seed phrase actually come from? Your entire wallet security reduces to that one moment of randomness. If entropy is weak or predictable, nothing else the device does can save you.

Here's how Blockstream Jade handles it.

Multiple independent entropy sources, not one chip

Jade gathers randomness from many independent sources: user button and wheel input, CPU counters, battery state, ambient temperature, a boot-time camera image, a hardware random number generator, and entropy from the companion app. No single point of failure. If any one source is somehow weak or compromised, the others still contribute real randomness.

A Bitcoin Core style entropy accumulator

Jade uses an accumulator similar to the design in Bitcoin Core, storing a 32-byte state generated by SHA512 hashing of its previous state along with all the entropy sources above, then feeds the result into the standard BIP39 function to produce your 12 or 24 word phrase. This directly addresses the attack class where attackers grind private keys searching for weakly generated ones, and you can verify it yourself: the implementation is published in random.c on GitHub, documented in the Jade Entropy wiki, and explained in plain English in Blockstream's Help Center.

Don't trust the device at all? Roll dice.

The Jade supports generating a recovery phrase with physical dice or any manual method, so your randomness never depends on any chip. You generate the phrase offline, enter the first 11 or 23 words, and the Jade calculates the valid BIP39 checksum word for you. Maximum sovereignty, zero trust in silicon.

No proprietary secure element to blindly trust

Jade secures your recovery phrase with a blind oracle (a "virtual secure element") instead of a proprietary secure-element chip, so an attacker would have to compromise both the device and the oracle to extract keys. The oracle stores only a PIN hash and a nonce and knows nothing about your addresses, private keys, or actual PIN. You can run Jade fully air-gapped via QR or host your own oracle instance.

Fully open source, top to bottom

Firmware, hardware schematics, and companion app code are all published for public audit. You don't have to take anyone's word on how your seed is generated. Read it, build it, verify it.

Back in stock at Solo Satoshi:

• Jade Classic, black plastic: $79
• Jade Plus, black plastic: $149
• Jade Plus, Lunar Silver metal: $169

All sourced directly from Blockstream, sealed, with same-day shipping. Jade Plus models also support Genuine Check to cryptographically verify your device is authentic hardware.

Your Gamma Hex ships ready to mine right out of the box. No firmware update is required to get started.

Please note that the Gamma Hex firmware is not yet available on the Bitaxe webflasher. We ask that you refrain from flashing your Gamma Hex with any other Bitaxe firmware currently listed on the flasher, as those builds are not compatible and will render the device unusable or bricked. Keeping the firmware your device shipped with ensures reliable operation.

Firmware is added to the webflasher once it has been merged into the main branch of ESP-Miner, so the flasher typically lags behind new releases. The Gamma Hex firmware remains fully open source, and the code is available for review here:

Source code: https://github.com/benjamin-wilson/ESP-Miner/tree/gamma-hex

Should you need the factory image or .bin file, it can be downloaded here:

Factory image: https://drive.google.com/file/d/18wZEfCngM5uGVexwzGJdBHozR45CM-TL/view?usp=sharing

The factory image can be flashed through the device UI, the recovery screen, or using the following flashing tool:

Flashing tool: https://esptool.spacehuhn.com/

When important updates are released, they are typically announced through GitHub or the official Bitaxe and OSMU channels, and we recommend monitoring those sources.

If you require additional assistance, please contact us at solosatoshi.com/support.

Huge thank you to everyone who supported the launch. The Bitaxe Gamma Hex is officially sold out and we're blown away by the response from this community.

If yours has already arrived, post it and tag us. We'd love to see them in the wild.

A new generation of desktop Bitcoin miners built on Bitmain's BM1373 chip is hitting the market, and the marketing deserves scrutiny. Watch for spec sheets that pair the overclocked hashrate with the low-power efficiency number. Those come from two different modes you can't run at the same time. One newer unit advertises 3.2 TH/s and ~11 J/TH in the same headline, but at 3.2 TH/s it actually runs 14.2 J/TH. Its honest stock operating point is 2.1 TH/s at 22W.

These chips are also carrying a heavy first-to-market premium.

So we ran the actual cost of ownership at both devices' stock chip frequencies, using the US median electricity rate of $0.17/kWh (chart attached):

Thor X1 (1× BM1373): 2.1 TH/s, 22W, 10.6 J/TH, $269
2× Bitaxe Gamma (BM1370): 2.4 TH/s, 36W, 15 J/TH, $144

Five-year net cost: $272 for the two Gammas vs $310 for the BM1373 unit. The newer chip's efficiency edge is real, but at residential rates it saves about $18/yr, meaning it takes ~7 years to repay the $125 price premium. Longer than these devices will realistically run, and the Gammas give you more hashrate and open-source firmware.

Neither earns a dime at residential rates. Every home miner is a slow-drip cost, not an income stream. Buy one for the hobby, the education, or the lottery ticket. Just do it with the real numbers, not the headline ones.

Meet the New & improved Bitaxe DUO in a preproduction sneak peak.

The Bitaxe DUO will fetaure 2 x BM1373 chips from the Antminer s23 and an upgraded LCD display screen.

The open-source bitcoin mining revolution continues!

Solo Satoshi is now stocking the Heatbit Bitair. Units officially land in September!

The Bitair is Heatbit's smallest device yet. It drops the heating function found in their Trio and Maxi models, shrinks the form factor, and cuts the price substantially. What's left is a True HEPA air purifier with a 1.2 TH/s solo Bitcoin miner in the same chassis, pulling 20 watts total.

Official Specifications

Spec	Detail
Hashrate	1.2 TH/s (SHA-256)
Power draw	20W total
Efficiency	16.7 J/TH
Noise	25 to 44 dB
Filtration	Multi-stage True HEPA
Particle capture	99.97% at 0.3 microns
Coverage	Up to 200 sq ft
Sensors	PM2.5, VOC, formaldehyde
Mining modes	Solo by default, pool switchable in app
Payouts	Solo win or Lightning
Solo odds	Roughly 1 in 17,200 per year for a full 3.125 BTC block
Price	$179.99 (Heatbit MSRP: $249)
Replacement filter	$20
Warranty	12-month Heatbit manufacturer warranty

What it Costs to Run.

20W continuous works out to 0.48 kWh per day, or 175.2 kWh per year running 24/7. At the US average rate of $0.12/kWh that is $1.75 per month, about $21 per year. Texas at $0.15/kWh runs $2.19 per month.

We are NOT Doing Pre-Sales

No deposits, no reservations, no waitlist you pay to join. The product page is live for one reason: the in-stock email. Everyone on that list gets notified at the same moment when September inventory arrives, then it is first come, first served.

Solo or Pool?

Solo mining is enabled by default, with no pool fees and no intermediaries taking a cut. Odds of hitting a block at 1.2 TH/s sit around 1 in 17,200 in a given year, so treat it as a lottery ticket that happens to hold down a day job. Pool mode is a toggle in the app if you would rather accumulate steadily. Either way it functions as a working air purifier whether it ever finds a block or not.

Product page and in-stock notification

Hey everyone,

Over the last several days, the Bitcoin community has been shaken by an ongoing incident involving Coldcard hardware wallets, made by Coinkite. A firmware bug affecting seed generation on certain older devices has been actively exploited, and funds have been lost. We're posting this to share what Coinkite has said in their own words, warn about the wave of scams that always follows events like this, and formally announce something we've been working toward.

To anyone here who has lost funds in this incident, our deepest condolences. Sats are more than numbers on a screen. They're time, work, and belief in a better system. What happened to you should not have happened to anyone.

What Happened

When a hardware wallet creates your seed phrase, one method uses a random number generator to pick words that no one could ever guess. The strength of that randomness is called entropy. Enough entropy means guessing your seed would take longer than the age of the universe. That's the whole reason a 12 or 24 word backup can safely protect real money.

On the affected Coldcard devices, a firmware bug caused the random number generator to fall back to a predictable software source instead of using true hardware randomness. Instead of picking from an unimaginably large pool of possibilities, the device was quietly picking from a much smaller pool that attackers could reproduce. That's how thousands of wallets were drained without anyone ever touching the physical devices.

Updating the firmware fixes new seeds going forward. It does not fix a seed that was already generated on the flawed firmware. That's why Coinkite is urging affected users to move their funds.

In Coinkite's Own Words

>

If you've ever generated a seed on a Coldcard device, please act on Coinkite's advisory now. Don't delay. The full technical advisory, including affected firmware versions and models and the updated firmware releases, is on the Coinkite blog: https://blog.coinkite.com/coldcard-mk3-seed-generation-warning/

Watch for Scams and Phishing

When events like this happen, scammers spike immediately. Expect fake emails, fake support pages, fake "recovery" tools, and fake urgency, all designed to trick you into typing your seed phrase somewhere it should never go.

• Verify every email. Check sender addresses carefully.
• Never enter your seed into a website or app. Ever.
• Never share your seed with anyone claiming to be from support. Not Coinkite, not us, not anyone.
• When in doubt, do nothing and ask the community before you act.

For real-time updates from trusted voices, the news feed on X is one of the fastest sources of accurate info right now. Follow verified accounts from Coinkite, the hardware wallet community, and Bitcoin devs you already know and trust.

Self-Custody is the Whole Point

Bitcoin is different from every asset that came before it because you can actually own it. Not a claim, not an IOU, not a balance an intermediary is holding for you. Real, direct ownership is the entire point.

Self-custody, holding your own keys and being your own bank, is what makes that ownership real. It's the harder path. It requires care, patience, and the right tools. This week is a painful reminder that it also requires the tools themselves to be trustworthy. That doesn't change our belief that self-custody is worth doing. It sharpens it.

Solo Satoshi Formally Supports the SeedSigner Project

We want to be transparent up front. This has been in the works for a while. The timing this week is an awkward coincidence, not opportunism. We had planned this announcement, and we chose to move forward with it rather than delay, because what happened this week is exactly why we believe in the philosophy behind it.

We're formally announcing our support for the SeedSigner project and the launch of the SeedSigner+ on our store. SeedSigner is an open-source, air-gapped Bitcoin signing device. The SeedSigner+ is sourced directly from the project's creator.

Open source matters! Code that anyone can read, that anyone can review, and that the community can inspect and fork is code that gets audited by many eyes over time. It's not a guarantee against bugs, nothing is, but it's the model we trust for hardware that holds Bitcoin.

What makes SeedSigner+ what it is:

• Stateless. Your seed exists only in volatile memory during a signing session and disappears the moment you unplug it
• No wireless. The Raspberry Pi Zero v1.3 has no WiFi or Bluetooth silicon
• Air-gapped operation via QR codes and the built-in camera
• Blank microSD by default. You download and verify the SeedSigner OS image yourself, so you never have to trust that a vendor put honest firmware on your device
• Sourced directly from the SeedSigner project creator
• Fully assembled in the USA, same-day shipping from Houston
• 90-day Solo Satoshi hardware warranty

Product page: https://www.solosatoshi.com/product/seedsigner/

Project: https://seedsigner.com and https://github.com/SeedSigner/seedsigner

Take care of yourselves and each other this week. If you have any questions, or you're unsure whether an email or message you received is legitimate, drop a comment or reach out to us directly and we'll help you sort it out.

Stack sats safely.

A single ASIC chip Bitaxe just found block 957382 on Public-Pool; taking home 3.138 BTC or $200,580.00. Public Pool has 0 fees which means the miner keeps 100% of the substity + fees.
