Recent Notes
The recent shipping-provider data breach affecting Trezor customers is a reminder of something we've always believed; the best way to protect customer data is to never require it in the first place.
A reminder for our customers: When ordering from us, you can:
โ Use an alias instead of your full legal name.
โ Ship to a PO Box instead of your home address.
โ Ship to FedEx and UPS drop off locations.
โ Check out with a throwaway or alias email address. (creating a new email is free, and services like Proton Mail take 2 minutes to set up).
If you ever need customer support, all we ask for is your order number. No name, no ID, no personal details required.
Your name, address, and email are only as safe as every third party that touches them. Minimize what you share, and there's nothing to leak.
Never enter your seed phrase on a website or share it with anyone.
Never click on any suspicious links.
Don't trust, verify.

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.

Proud to stand with Bitcoin Policy Institute and this coalition.
Attackers already use AI without limits. The people defending open-source financial infrastructure shouldn't be the ones held back.
Defenders need the frontier.

Gamma Hex Firmware Advisory
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 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. 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.

Run the Numbers Before you Buy the Hype of the New BM1373 Home Miners.
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 (1ร BM1373): 2.1 TH/s, 22W, 10.6 J/TH, $269
2ร 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.

An important message for the Bitcoin community.
Over the last several days, the community has been shaken by an ongoing security 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.
If you have ever generated a seed on a Coldcard device, Coinkite is urging you to move your funds now. Do not delay. Read their official advisory here: https://blog.coinkite.com/coldcard-mk3-seed-generation-warning/
In Coinkite CEO Rodolfo Novak's own words: "If you generated a seed using a Coldcard wallet, move your funds now, using our updated best practices, before reading further."
To anyone who has lost funds in this incident, our deepest condolences. Sats are more than numbers on a screen. They are time, work, and belief in a better system.
โ ๏ธ Watch for scams. Events like this always trigger a wave of phishing emails, fake support pages, and fake "recovery" tools. Verify every email. Never enter your seed into a website. Never share your seed with anyone claiming to be from support. Follow verified accounts on X for real-time updates.
Self-custody is the whole point of Bitcoin. Real, direct ownership of your coins, no intermediary. This week is a painful reminder that the tools we use for self-custody have to be trustworthy. That does not change our belief in self-custody. It sharpens it.
We are also formally announcing something we have been working toward for a while: Solo Satoshi now supports the SeedSigner project. The timing this week is an awkward coincidence, not opportunism. We chose to move forward because what happened this week is exactly why we believe in the philosophy behind open-source hardware.
SeedSigner is an open-source, air-gapped Bitcoin signing device. Stateless design (nothing persists after power-off), no WiFi or Bluetooth silicon on the board, and a blank microSD by default so you flash and verify the software yourself. Assembled in the USA and sourced directly from the project's creator.
