Last Notes
I have this sort of sense that you shouldn’t really be able to cleanly articulate what you do to anybody.
Like if someone asks what you do and you say “radiologist” or “lawyer”that it’s somehow a bad thing or at least not optimal.
I’ve felt this for a long time now, but I usually don’t say it because it’s so counter to common culture and I also think the people who know what I mean already get it and the people who don’t, don’t.
But to detail it, It’s something like the world is moving really fast and changing very rapidly and in order to be taking advantage of that you want to be doing the job which has no name and which couldn’t even have been conceived of 10-15 years ago.
Something that is only presently possible, but still not well enough understood to be classified. It’s not legible to outsiders and so it’s harder to explain yourself, harder to credential yourself or to raise money, but that friction is the moat.
That’s sort of the sweet spot for growth maximization.
To me anyway.
Anthropic built an AI model so powerful they decided they couldn't release it to the world.
Claude Mythos is a frontier model that was finding high-severity vulnerabilities in the world's most critical software. In every major operating system, in every major web browser. Thousands of them. It surpasses all but the most elite human security researchers at finding and exploiting flaws.
Anthropic essentially said: "this breaks everything if it gets into the wrong hands."
So they formed Project Glasswing, a consortium of AWS, Apple, Google, Microsoft, NVIDIA, Cisco, CrowdStrike, and JPMorgan to work together to secure the world's most critical infrastructure FIRST.
This is the cybersecurity equivalent of the Manhattan Project, except this time the scientists are choosing to lock it in a vault and only hand the keys to the people building the shields.
If your first reaction is "that's terrifying", good! Things as accelerating incredibly fast.

Thank you so much to everyone who has sent their love and prayers to Carla and our family. The number of people who have reached out saying “my wife and child almost died too” is truly staggering… Thank you for sharing your stories. The fact that these terrifying near-death experiences are so shockingly common (especially during pregnancy/childbirth) is a great reminder of how absolutely brutal and deadly most of human history has been… We are so fortunate to live at a time when modern medicine can save people who would have been guaranteed to die for 99.999% of human history… beyond grateful to the doctors, nurses, and paramedics who saved her life and the life of the baby in her belly. Carla is still in a lot of pain but she’s resting a bit now, thank god.

BIP85 for Mortals
How to stop managing ten recovery phrases with a single one
If you have ever had more than one bitcoin wallet, you already know the problem. Each one has its own recovery words, its own piece of paper stored somewhere safe, its own mental note about where it is and what it is called. With two wallets, it is manageable. With five, it starts to become chaos. With ten, it is a time bomb.
BIP85 is the answer the Bitcoin ecosystem took years to formalize. The idea is simple and powerful at the same time: instead of managing a collection of independent seeds, you generate them all from a single one. One master seed. The rest are derived from it in a mathematical, predictable way, without any of the derived ones compromising the original.
Why having multiple wallets makes sense — and why it is a problem
Separating funds is a reasonable practice. One wallet for everyday use with small amounts, another for long-term savings that you do not touch, one for family-related funds, another to test a new app without risking anything important. That separation is good self-custody hygiene.
The problem is the operational cost. Every new wallet means a new seed phrase: between 12 and 24 words that represent complete access to those funds. Losing them is the same as losing the wallet. If someone finds them, that someone has the wallet. So they need to be stored properly, in secure and separate physical locations, and you need to remember which set of words belongs to which wallet.
Most people end up simplifying in dangerous ways: reusing phrases, storing several in the same place, or simply giving up on separating funds because the maintenance is too tedious. The result is worse than not having tried.
BIP85 solves that conflict at the root.
What exactly is a seed, and why does it matter?
When you create a bitcoin wallet, the device or application generates a set of words — usually 12 or 24 — known as a seed phrase or recovery phrase. In practice, those words are the wallet. Whoever has them has access to the funds. Whoever loses them loses access forever.
A seed phrase is not a password you can change or reset. It is the mathematical root from which all the wallet’s keys are derived. Without it, there is no recovery.
BIP85 starts from that same principle and extends it: if one seed phrase can generate a whole tree of keys, why not also use it to generate other complete, independent seed phrases?
How it works, without the math
Imagine a secret recipe that only you know. A unique combination of ingredients that no one else has. That recipe is your master seed.
BIP85 lets you create other recipes from it. The master recipe combined with the number 0 always produces the same derived recipe A. Combined with the number 1, it always produces the same derived recipe B. And so on, for as many as you need. Always the same result for the same ingredients: no randomness, no surprises.
That number that distinguishes each derivation is called the index. Index 0 always produces the same child seed. Index 1 always produces another one. They are deterministic: given the same master seed and the same index, the result is always identical. There is no randomness involved.
What makes this useful and secure at the same time is that the process only works in one direction. Whoever has the child seed cannot reconstruct the master seed from it. The parent can generate children; the children reveal nothing about the parent.
Child seeds can be generated in whatever length you prefer: 12, 18, or 24 words, depending on what you request when deriving them. In every respect, they are standard BIP39 phrases.
What it is useful for in practice
The most direct application is managing multiple wallets with a single backup.
A daily spending wallet derived with index 0. A long-term savings wallet with index 1. One to give a family member access to part of your funds without revealing the main seed, with index 2. Under the conventional system, each of those wallets needs its own separate set of words stored independently. With BIP85, they all come from the same master seed, and it is enough to protect that one secret.
The child seed you derive is a completely normal, standard seed phrase, compatible with any wallet that follows BIP39. It carries no special marker. Whoever receives it does not know it is a derivation: it works exactly like any other seed phrase.
This has an important practical consequence for inheritance and delegation. Emergency instructions for a family member or executor become simpler: one master phrase, plus a list of which index corresponds to which wallet. Much more manageable than multiple sealed envelopes with independent phrases.
The advanced use almost no one mentions: derived passphrases
There is a BIP85 use case that rarely appears in educational content and that, for anyone already practicing self-custody with some seriousness, is probably the most interesting one: deriving BIP39 passphrases from the master seed.
A BIP39 passphrase — the “25th word” — is an optional extra layer added to a seed phrase to create a different hidden wallet. It is one of the strongest defenses against physical coercion and against accidental discovery of your backup phrase. The classic problem is that the passphrase itself also has to be remembered or stored, and if you lose it, you lose access to the hidden wallet even if you still have the seed phrase.
BIP85 solves that: instead of inventing a passphrase and memorizing it, you derive it mathematically from your master seed using an index. If you ever lose it, you regenerate it. And because each index produces a different passphrase, you can have multiple hidden wallets reproducible from a single root secret, without having to store anything extra.
The same logic applies to alphanumeric passwords for external services. Reproducible, strong, and independent of any third-party password manager.
What happens if you lose a child seed
This is the question that feels most reassuring once you hear the right answer.
Suppose you have a daily-use wallet derived with index 1, and the paper where you wrote down its words gets lost or destroyed. With your master seed, and knowing you used index 1, you can regenerate that exact same child seed at any time from any compatible device. The funds are not lost.
The process is straightforward: you enter the master seed into a BIP85-compatible device, specify the index, and the device regenerates the exact child phrase. You import it into the destination wallet and recover full access.
What is irreversible is losing the master seed. If that happens, you lose access to every wallet derived from it, without exception. The master seed is the single critical point of the whole system. All the complexity reduction BIP85 offers comes with that trade-off: the responsibility for custody is concentrated into one secret.
There is one good practice before moving real funds: generate a child seed with a specific index, write down which index you used, delete the child, and then regenerate it from the master to verify that it matches. Only once you have confirmed that the recovery cycle works correctly on your device should you move real funds into those wallets.
What BIP85 does not do
It is worth being precise about its limits.
BIP85 does not encrypt your funds or add any extra protection to real-time wallet access. Its function is to manage the generation and backup of seeds. It is not an extra lock on transactions.
It also does not eliminate custody risk: it concentrates it. If you used to have five seeds and now you have one, that master seed becomes the single point of failure for the whole system. More operational simplicity means more weight on that one secret. Anyone using BIP85 seriously should give that master seed the same level of care — or more — than they used to give five separate seeds. A steel plate, not paper. Two physical locations, not one. Never photographed, never stored digitally.
Finally, BIP85 requires explicit support from the device or application you use. Not every hardware or software wallet implements it, and support status changes with firmware updates. Coldcard by Coinkite is the reference implementation and the most mature one. Ian Coleman’s web tool can also calculate it manually, with the essential precaution of downloading the HTML and always using it with the device offline.
Why it is worth knowing about
Most bitcoin lost in self-custody was not lost to sophisticated hacks or protocol failures. It was lost to management mistakes: poorly stored phrases, forgotten backups, destroyed papers, heirs without clear instructions, abandoned wallets because maintaining so many separate phrases was simply too much work.
That is the real problem of self-custody, and it is one of the few areas where there have been very few structural improvements in the last decade. BIP85 is one of them. It does not remove risk — it reorganizes it, concentrates it, makes it manageable. One well-protected secret is, in practice, a safer system than five poorly protected ones, even if at first glance it seems like the opposite.
For someone already managing multiple wallets seriously, ignoring BIP85 comes with a real operational cost that grows with every new wallet, every hardware change, and every delayed inheritance conversation. It is one of those quiet pieces of infrastructure that does not solve anything in a spectacular way, but the day you need it, it saves you exactly the kind of mistake that can ruin years of savings.
To go deeper
— BIP85, official specification. The technical document, concise and readable if you want the detail.
— Ian Coleman’s BIP39/BIP85 tool. Useful for understanding how the output changes with the index. Always use it offline: download the HTML, disconnect from Wi-Fi before opening it, and ideally use it on a machine that is not part of your everyday setup.
— Device support documentation: Coldcard, BitBox02, Passport. Always verify BIP85 support against the current firmware before depending on it.

In the past year I've personally raised about $15k USD in funding for Ukrainian military projects with Bitcoin. And I've barely even tried.
I could use another 850,000sats for my latest project actually, getting Flash Battalion another van: https://mempool.space/address/bc1qdds28nk2n69kc2zh0y62flnxarsp2lv80tn8t5
On a bigger scale, this is total nonsense. The biggest funders of war and violence right now are Russia and Iran. In both cases their ultimate primary funding source is oil and gas revenue; in the case of Russia a lesser funding source is the Russian government's ability to force companies to simply work for free in exchange for future promises of income that both sides know will probably never be paid. Fiat currency has nothing to do with that, and Bitcoin only fixes that problem to the extent that it allows societies to rise up.
But in Russia the population genuinely supports war. That's probably true for most of Iran too. They're infested with Islamic psychopaths.
Even if you think the US and other Western countries are the cause of "war", the argument still fails: the US only spends a small part of total GDP on their military. A Bitcoin standard doesn't change anything there.

a pseudonymous dev launched a solana token project that endlessly mints tokens to sell to retail for bitcoin, his stated goal is to accumulate as much bitcoin as possible, he issues tokens without a set schedule, he can effectively choose at will when to print more tokens and sell them, each token represents equity in the company holding bitcoin, but token holders have little to no governance rights
recently, he created a staking ecosystem with four yield bearing derivative tokens funded by sales of the main token, if you stake them for a month, he pays you usdc
many bitcoiners would call that a scam, but if you slap a suit on the dev, and list the tokens on the nasdaq, its the “most important bitcoin company”

Good morning nostr, today i might do some work at the cabin, just to have it ready in case someone else visits soon. I was thinking about the kiddos that were here over the weekend, and how they need their parents to do every single thing with them (11 yrs old). I remember we wanted to go play as far away from the adults as possible, so we could do more stuff. Many kids today are so coddled, and disrespectful too. Anyway, i hope they grow up to be responsible adults some day, otherwise they'll have a tough time. But at least the weekend is over and we have our quiet back, it just hit me how so many parents allow their kids to make the rules. But its coffeetime now and i have a busy day ahead. Yall have a great tuesday, enjoy your coffee, and do your work with a happy heart. #coffeechain

A guy on a podcast I listened to thinks bitcoin is going to 0 because governments around the world will realize there’s not enough energy to go around and ban it. He had a chance to buy at a couple of bucks. Oh, and he’s an economist.
The logic is… it’ll fail in 30 years so I won’t buy it at $2 even to sell at $60k lol…
Maybe someone should send him a chart of how much energy his AI chatbot uses…
