If you’re “paid by the hour” then why not “receive by the hour”? #cashu can fix this.

Small to medium sized businesses can run their own mints and stream sats to their employees as they work. Why wait an arbitrary 2 weeks?

One day we’ll look back and wonder why we ever worked for days and weeks before getting paid.

There’s also access to much more energy than here on earth which may entice the bitcoin mining industry in the long run.

If we ever manage to mine asteroids efficiently then we can expect very large solar arrays parked in a tighter orbit around the sun and used for bitcoin mining among other things. Hard to imagine a cheaper and more reliable energy source than that if we’re already out there.

Came to Nostr for tea and crumpets. Stayed for the revolution.

We're excited to launch our new company, [NosFabrica](https://nosfabrica.com/)! Our mission is to empower sovereign healthcare by building tools for peer-to-peer healthcare interactions, giving individuals and providers the keys to their own health data. We are building a healthcare application factory, shipping health clients built on Nostr and Bitcoin and bootstrapping a decentralized ecosystem of health tools. We want to onboard thousands of people to Nostr and Bitcoin and enable people to live healthy lives. By utilizing Nostr for identity resolution and bitcoin for payments, we're paving the way for interoperable healthcare applications to exchange health information, and individuals to track and own data that matters to them, connecting to healthcare providers on their health journey.

**The Problem:**

The fiat healthcare system has led to a dangerous centralization of healthcare records in the US and globally, where companies ultimately own health data, not individuals. Current protocols of oAuths and APIs have led to bloated and expensive walled gardens (eg, Epic, Cerner) and a honeypot for healthcare hackers, most notably the recent [Change Healthcare hack](https://medriva.com/news/healthcare-policy/cyberattack-on-change-healthcare-exposes-fragility-in-us-health-system-infrastructure), owned by United Healthcare - affecting Avi's work. In 2023, [more than 115 million health records were compromised across 655 data breaches](https://www.medtechdive.com/news/patient-records-exposed-healthcare-data-breaches-double-fortified-health-security/705149/).

High cost and poor outcomes are the current product of fiat healthcare. Of the [$4.5 trillion annual US healthcare spend](https://www.kff.org/from-drew-altman/the-two-health-care-cost-crises/), [25% is administrative cost](https://www.pgpf.org/blog/2023/04/almost-25-percent-of-healthcare-spending-is-considered-wasteful-heres-why#:~:text=Approximately%2025%20percent%20of%20healthcare,interventions%20that%20address%20such%20waste.), and half of that is waste. [6-10% ](https://www.businessnewsdaily.com/8693-medical-billing-services.html)of every healthcare transaction goes to a medical billing middleman. Meanwhile, [6 in 10 Americans](https://www.cdc.gov/chronic-disease/about/index.html) has a chronic health condition.

A decentralized healthcare application ecosystem would give the healthy sovereign individual the opportunity to take back ownership of their healthcare data, and their health, too.

**The Solution:**

NosFabrica means "our factory" in Latin, with of course the nod to Nostr. We aim to build a new, parallel health system on top of open source protocols Nostr and bitcoin. This decentralized healthcare ecosystem will be driven by peer-to-peer interactions between patients and providers. We will move healthcare onto a bitcoin and Nostr standard, giving independent healthcare providers the tools to integrate bitcoin deeper into their practice while maintaining practice sovereignty.

By establishing an open-source protocol for the private exchange of health data on Nostr, NosFabrica will set a foundation for a decentralized healthcare system and enable bitcoin-native electronic medical record (EMR) software clients to be built on top of Nostr.

We will cut out middlemen in healthcare and build tools that put the individual at the center of the solution. The benefits to patients include owning their own medical data, care discovery at competitive prices, portability of health data, and ultimately improve health outcomes. Doctors will also have the ability to reach a much broader population, reduce their administrative cost, and own their key demographic data such as licenses, credentials, and board certifications. Ultimately, we envision a more robust ecosystem of independent providers, combatting the trend of [M&A and centralization](https://www.finalis.com/blog/healthcare-m-a-2024-recent-deals-and-trends) we see under the current fiat healthcare regime.

There are several impacts for the broader free and open-source community, as it gives tools for individuals with different healthcare use cases to bring solutions to sorely needed applications such as medical consent, data sharing, clinical trials, and public health.

**Nostr enables the NosFabrica future in three primary ways.**

**Identity and Access:**

- User identity exists at the protocol layer via your npub/nsec, instead of the application layer.

- Users can sign into any application connected to the protocol

- Users can sign and certify events with their key pair, verifiably demonstrating ownership

**Data Standardization**

- We can develop specific Nostr event "kinds" created for medical data. Vitor has already started by building [NIP-82 for medical data.](https://github.com/nostr-protocol/nips/pull/357)

- Existing international data standards and formats such as [FHIR/HL7](https://fhir.org/) can be "wrapped" within Nostr events"

- This structure provides seamless data portability and interoperability across applications.

**Persistence and Availability:**

- HIPAA compliant, encrypted healthcare data is stored on relays

- Only the owner of the data and those authorized by the owner can decrypt or view the data - in other words, selective disclosure, which is a cornerstone of privacy.

Boosting the Nostr network effect and flywheel will continue, as there are already [40,000 weekly active users](https://nostr.band/). By building healthcare applications on Nostr, we can onboard more people to the ecosystem, who may not be interested in social media.

**Call to Action:**

Of course, Nostr and Bitcoin are global protocols and networks that anyone can opt into. While the US gets a lot of the focus due to its expensive and complex healthcare system, there are many challenges globally including healthcare access, affordability, and timely care that we can address with open source tools and permissionless, sound money. We'd love to hear from you if you're interested in joining our mission.

**About the team:**

Avi Burra is an experienced healthcare veteran, working as senior director of product management at Optum. He is also the host of [PlebChain Radio](https://fountain.fm/show/0N6GGdZuYNNG7ysagCg9), a leading bitcoin and nostr podcast.

Great mission and best of luck to you guys!

Last year I worked on pulling data off of devices like Garmin watches, heart rate, and blood pressure monitors and writing parquet files for portability. With that you can do anomaly detection, plot graphs, etc. using standard python packages.

The goal was to build an open source system for preventative healthcare based on passively collected medical data. Pair it with a fine tuned LLM and a collection of tools for it to use and you might improve health outcomes for people who would otherwise not see a doctor.

Now that you are your own bank, time to be your own comms network:

The big AI players like OpenAI are building in personalized responses based on your prior chat history. It’s helpful but it leads to lock in. Imagine after using it for a year or two and it knows you well how likely are you to switch to another platform?

If you run your own bitcoin node you can run your own LLM infrastructure.

Worked hard for the last few months and now it’s time to play hard. I’ll be offline for the next 5 days to recharge the soul. See you all in a few days!

In other words, “true randomness” is relative to the observer. There’s a continuum between cryptographically secure randomness and “true” randomness. True randomness occurs when the Kolmogorov complexity [1] of the random process exceeds the maximum possible computational budget of the observer while cryptographically secure randomness occurs when the complexity exceeds the observer’s budget on a sufficiently long time scale.

Some thoughts on randomness and how it relates to computation.

Computation is the act of following rules to transform inputs into outputs.

Computational irreducibility is the idea that for some systems the output can’t be predicted from the input without performing the computation. For example the SHA256 of a string is deterministic and computable (therefore the output is not truly random) but there are no shortcuts for getting the output aside from doing all the steps.

The path a ball takes when you throw it on the other hand is computationally reducible since we have equations of motion and can predict where it goes before throwing it.

Computational irreducibility is a necessary component of true randomness but it’s not sufficient.

So then what does it mean to be truly random? In this context my best guess is that it’s a process whose compute requirements exceed what’s available to the observer. The observer (the person or system interacting with the “random” process) can’t run the algorithm needed to produce the apparent randomness.

Example: suppose you have a computer with only 7 bytes of memory. You can’t perform SHA256 since you need at least 8 bytes of memory for the registers alone and you obviously need a budget for storing the algorithm itself. The output of SHA256 would be forever appear random to your computer.

Only tried commenting on Primal mobile. I couldn’t load the link on web at all when I tried on my laptop via the share link.

For what it’s worth I only see the single note and can’t seem to comment on it via Primal.

Thanks for sharing that bit of history by the way!

John von Neumann did something similar for general purpose computers. He widely circulated a report detailing the EDVAC design [1] for a full year before the others on the design team could file a patent and now we have the ubiquitous "von Neumann architecture" [2].

Because it was circulating publicly for a full year before a patent was filed, it could no longer be patented and we now have the prevalent “von Neumann” architecture.

I got an email from nostr:nprofile1qqs9v9et20mnqagtgrnrc5qmzcrgmkt2y3087p23vawqlmyczlhfdcqpzpmhxue69uhkummnw3ezuamfdejszxmhwden5te0vejk2ern9ehx7um5wghxyctwvshhq6trwvq3vamnwvaz7tmjv4kxz7fwdehhxarj9e3xzmnyrwt363 saying that some of my data was being deleted automatically.

Although that data is still exposed elsewhere, I really appreciate that Coinkite is at least trying to limit the attack surface for my data automatically.

Good move. Keep up the good work.

Can confirm they do a great job limiting how much info they need to collect up front too. Would recommend.
