2025-05-20 15:53:48This piece is the first in a series that will focus on things I think are a priority if your focus is similar to mine: building a strong family and safeguarding their future.
Choosing the ideal place to raise a family is one of the most significant decisions you will ever make. For simplicity sake I will break down my thought process into key factors: strong property rights, the ability to grow your own food, access to fresh water, the freedom to own and train with guns, and a dependable community.
A Jurisdiction with Strong Property Rights
Strong property rights are essential and allow you to build on a solid foundation that is less likely to break underneath you. Regions with a history of limited government and clear legal protections for landowners are ideal. Personally I think the US is the single best option globally, but within the US there is a wide difference between which state you choose. Choose carefully and thoughtfully, think long term. Obviously if you are not American this is not a realistic option for you, there are other solid options available especially if your family has mobility. I understand many do not have this capability to easily move, consider that your first priority, making movement and jurisdiction choice possible in the first place.
Abundant Access to Fresh Water
Water is life. I cannot overstate the importance of living somewhere with reliable, clean, and abundant freshwater. Some regions face water scarcity or heavy regulations on usage, so prioritizing a place where water is plentiful and your rights to it are protected is critical. Ideally you should have well access so you are not tied to municipal water supplies. In times of crisis or chaos well water cannot be easily shutoff or disrupted. If you live in an area that is drought prone, you are one drought away from societal chaos. Not enough people appreciate this simple fact.
Grow Your Own Food
A location with fertile soil, a favorable climate, and enough space for a small homestead or at the very least a garden is key. In stable times, a small homestead provides good food and important education for your family. In times of chaos your family being able to grow and raise healthy food provides a level of self sufficiency that many others will lack. Look for areas with minimal restrictions, good weather, and a culture that supports local farming.
Guns
The ability to defend your family is fundamental. A location where you can legally and easily own guns is a must. Look for places with a strong gun culture and a political history of protecting those rights. Owning one or two guns is not enough and without proper training they will be a liability rather than a benefit. Get comfortable and proficient. Never stop improving your skills. If the time comes that you must use a gun to defend your family, the skills must be instinct. Practice. Practice. Practice.
A Strong Community You Can Depend On
No one thrives alone. A ride or die community that rallies together in tough times is invaluable. Seek out a place where people know their neighbors, share similar values, and are quick to lend a hand. Lead by example and become a good neighbor, people will naturally respond in kind. Small towns are ideal, if possible, but living outside of a major city can be a solid balance in terms of work opportunities and family security.
Let me know if you found this helpful. My plan is to break down how I think about these five key subjects in future posts.

2025-05-20 15:50:48For years American bitcoin miners have argued for more efficient and free energy markets. It benefits everyone if our energy infrastructure is as efficient and robust as possible. Unfortunately, broken incentives have led to increased regulation throughout the sector, incentivizing less efficient energy sources such as solar and wind at the detriment of more efficient alternatives.
The result has been less reliable energy infrastructure for all Americans and increased energy costs across the board. This naturally has a direct impact on bitcoin miners: increased energy costs make them less competitive globally.
Bitcoin mining represents a global energy market that does not require permission to participate. Anyone can plug a mining computer into power and internet to get paid the current dynamic market price for their work in bitcoin. Using cellphone or satellite internet, these mines can be located anywhere in the world, sourcing the cheapest power available.
Absent of regulation, bitcoin mining naturally incentivizes the build out of highly efficient and robust energy infrastructure. Unfortunately that world does not exist and burdensome regulations remain the biggest threat for US based mining businesses. Jurisdictional arbitrage gives miners the option of moving to a friendlier country but that naturally comes with its own costs.
Enter AI. With the rapid development and release of AI tools comes the requirement of running massive datacenters for their models. Major tech companies are scrambling to secure machines, rack space, and cheap energy to run full suites of AI enabled tools and services. The most valuable and powerful tech companies in America have stumbled into an accidental alliance with bitcoin miners: THE NEED FOR CHEAP AND RELIABLE ENERGY.
Our government is corrupt. Money talks. These companies will push for energy freedom and it will greatly benefit us all.

2025-05-27 09:21:53The new website is finally live! I put in a lot of hard work over the past months on it. I'm proud to say that it's out now and it looks pretty cool, at least to me!
Why rewrite it all?
The old kycnot.me site was built using Python with Flask about two years ago. Since then, I've gained a lot more experience with Golang and coding in general. Trying to update that old codebase, which had a lot of design flaws, would have been a bad idea. It would have been like building on an unstable foundation.
That's why I made the decision to rewrite the entire application. Initially, I chose to use SvelteKit with JavaScript. I did manage to create a stable site that looked similar to the new one, but it required Jav aScript to work. As I kept coding, I started feeling like I was repeating "the Python mistake". I was writing the app in a language I wasn't very familiar with (just like when I was learning Python at that mom ent), and I wasn't happy with the code. It felt like spaghetti code all the time.
So, I made a complete U-turn and started over, this time using Golang. While I'm not as proficient in Golang as I am in Python now, I find it to be a very enjoyable language to code with. Most aof my recent pr ojects have been written in Golang, and I'm getting the hang of it. I tried to make the best decisions I could and structure the code as well as possible. Of course, there's still room for improvement, which I'll address in future updates.
Now I have a more maintainable website that can scale much better. It uses a real database instead of a JSON file like the old site, and I can add many more features. Since I chose to go with Golang, I mad e the "tradeoff" of not using JavaScript at all, so all the rendering load falls on the server. But I believe it's a tradeoff that's worth it.
What's new
- UI/UX - I've designed a new logo and color palette for kycnot.me. I think it looks pretty cool and cypherpunk. I am not a graphic designer, but I think I did a decent work and I put a lot of thinking on it to make it pleasant!
- Point system - The new point system provides more detailed information about the listings, and can be expanded to cover additional features across all services. Anyone can request a new point!
- ToS Scrapper: I've implemented a powerful automated terms-of-service scrapper that collects all the ToS pages from the listings. It saves you from the hassle of reading the ToS by listing the lines that are suspiciously related to KYC/AML practices. This is still in development and it will improve for sure, but it works pretty fine right now!
- Search bar - The new search bar allows you to easily filter services. It performs a full-text search on the Title, Description, Category, and Tags of all the services. Looking for VPN services? Just search for "vpn"!
- Transparency - To be more transparent, all discussions about services now take place publicly on GitLab. I won't be answering any e-mails (an auto-reply will prompt to write to the corresponding Gitlab issue). This ensures that all service-related matters are publicly accessible and recorded. Additionally, there's a real-time audits page that displays database changes.
- Listing Requests - I have upgraded the request system. The new form allows you to directly request services or points without any extra steps. In the future, I plan to enable requests for specific changes to parts of the website.
- Lightweight and fast - The new site is lighter and faster than its predecessor!
- Tor and I2P - At last! kycnot.me is now officially on Tor and I2P!
How?
This rewrite has been a labor of love, in the end, I've been working on this for more than 3 months now. I don't have a team, so I work by myself on my free time, but I find great joy in helping people on their private journey with cryptocurrencies. Making it easier for individuals to use cryptocurrencies without KYC is a goal I am proud of!
If you appreciate my work, you can support me through the methods listed here. Alternatively, feel free to send me an email with a kind message!
Technical details
All the code is written in Golang, the website makes use of the chi router for the routing part. I also make use of BigCache for caching database requests. There is 0 JavaScript, so all the rendering load falls on the server, this means it needed to be efficient enough to not drawn with a few users since the old site was reporting about 2M requests per month on average (note that this are not unique users).
The database is running with mariadb, using gorm as the ORM. This is more than enough for this project. I started working with an
sqlite
database, but I ended up migrating to mariadb since it works better with JSON.The scraper is using chromedp combined with a series of keywords, regex and other logic. It runs every 24h and scraps all the services. You can find the scraper code here.
The frontend is written using Golang Templates for the HTML, and TailwindCSS plus DaisyUI for the CSS classes framework. I also use some plain CSS, but it's minimal.
The requests forms is the only part of the project that requires JavaScript to be enabled. It is needed for parsing some from fields that are a bit complex and for the "captcha", which is a simple Proof of Work that runs on your browser, destinated to avoid spam. For this, I use mCaptcha.

2025-05-06 01:37:28I remember the first gathering of Nostr devs two years ago in Costa Rica. We were all psyched because Nostr appeared to solve the problem of self-sovereign online identity and decentralized publishing. The protocol seemed well-suited for textual content, but it wasn't really designed to handle binary files, like images or video.
The Problem
When I publish a note that contains an image link, the note itself is resilient thanks to Nostr, but if the hosting service disappears or takes my image down, my note will be broken forever. We need a way to publish binary data without relying on a single hosting provider.
We were discussing how there really was no reliable solution to this problem even outside of Nostr. Peer-to-peer attempts like IPFS simply didn't work; they were hopelessly slow and unreliable in practice. Torrents worked for popular files like movies, but couldn't be relied on for general file hosting.
Awesome Blossom
A year later, I attended the Sovereign Engineering demo day in Madeira, organized by Pablo and Gigi. Many projects were presented over a three hour demo session that day, but one really stood out for me.
Introduced by hzrd149 and Stu Bowman, Blossom blew my mind because it showed how we can solve complex problems easily by simply relying on the fact that Nostr exists. Having an open user directory, with the corresponding social graph and web of trust is an incredible building block.
Since we can easily look up any user on Nostr and read their profile metadata, we can just get them to simply tell us where their files are stored. This, combined with hash-based addressing (borrowed from IPFS), is all we need to solve our problem.
How Blossom Works
The Blossom protocol (Blobs Stored Simply on Mediaservers) is formally defined in a series of BUDs (Blossom Upgrade Documents). Yes, Blossom is the most well-branded protocol in the history of protocols. Feel free to refer to the spec for details, but I will provide a high level explanation here.
The main idea behind Blossom can be summarized in three points:
- Users specify which media server(s) they use via their public Blossom settings published on Nostr;
- All files are uniquely addressable via hashes;
- If an app fails to load a file from the original URL, it simply goes to get it from the server(s) specified in the user's Blossom settings.
Just like Nostr itself, the Blossom protocol is dead-simple and it works!
Let's use this image as an example:
If you look at the URL for this image, you will notice that it looks like this:
blossom.primal.net/c1aa63f983a44185d039092912bfb7f33adcf63ed3cae371ebe6905da5f688d0.jpg
All Blossom URLs follow this format:
[server]/[file-hash].[extension]
The file hash is important because it uniquely identifies the file in question. Apps can use it to verify that the file they received is exactly the file they requested. It also gives us the ability to reliably get the same file from a different server.
Nostr users declare which media server(s) they use by publishing their Blossom settings. If I store my files on Server A, and they get removed, I can simply upload them to Server B, update my public Blossom settings, and all Blossom-capable apps will be able to find them at the new location. All my existing notes will continue to display media content without any issues.
Blossom Mirroring
Let's face it, re-uploading files to another server after they got removed from the original server is not the best user experience. Most people wouldn't have the backups of all the files, and/or the desire to do this work.
This is where Blossom's mirroring feature comes handy. In addition to the primary media server, a Blossom user can set one one or more mirror servers. Under this setup, every time a file is uploaded to the primary server the Nostr app issues a mirror request to the primary server, directing it to copy the file to all the specified mirrors. This way there is always a copy of all content on multiple servers and in case the primary becomes unavailable, Blossom-capable apps will automatically start loading from the mirror.
Mirrors are really easy to setup (you can do it in two clicks in Primal) and this arrangement ensures robust media handling without any central points of failure. Note that you can use professional media hosting services side by side with self-hosted backup servers that anyone can run at home.
Using Blossom Within Primal
Blossom is natively integrated into the entire Primal stack and enabled by default. If you are using Primal 2.2 or later, you don't need to do anything to enable Blossom, all your media uploads are blossoming already.
To enhance user privacy, all Primal apps use the "/media" endpoint per BUD-05, which strips all metadata from uploaded files before they are saved and optionally mirrored to other Blossom servers, per user settings. You can use any Blossom server as your primary media server in Primal, as well as setup any number of mirrors:
## Conclusion
For such a simple protocol, Blossom gives us three major benefits:
- Verifiable authenticity. All Nostr notes are always signed by the note author. With Blossom, the signed note includes a unique hash for each referenced media file, making it impossible to falsify.
- File hosting redundancy. Having multiple live copies of referenced media files (via Blossom mirroring) greatly increases the resiliency of media content published on Nostr.
- Censorship resistance. Blossom enables us to seamlessly switch media hosting providers in case of censorship.
Thanks for reading; and enjoy! 🌸

2025-05-03 21:54:45Introduction
Me and Fishcake have been working on infrastructure for Noswhere and Nostr.build. Part of this involves processing a large amount of Nostr events for features such as search, analytics, and feeds.
I have been recently developing
nosdex
v3, a newer version of the Noswhere scraper that is designed for maximum performance and fault tolerance using FoundationDB (FDB).Fishcake has been working on a processing system for Nostr events to use with NB, based off of Cloudflare (CF) Pipelines, which is a relatively new beta product. This evening, we put it all to the test.
First preparations
We set up a new CF Pipelines endpoint, and I implemented a basic importer that took data from the
nosdex
database. This was quite slow, as it did HTTP requests synchronously, but worked as a good smoke test.Asynchronous indexing
I implemented a high-contention queue system designed for highly parallel indexing operations, built using FDB, that supports: - Fully customizable batch sizes - Per-index queues - Hundreds of parallel consumers - Automatic retry logic using lease expiration
When the scraper first gets an event, it will process it and eventually write it to the blob store and FDB. Each new event is appended to the event log.
On the indexing side, a
Queuer
will read the event log, and batch events (usually 2K-5K events) into one work job. This work job contains: - A range in the log to index - Which target this job is intended for - The size of the job and some other metadataEach job has an associated leasing state, which is used to handle retries and prioritization, and ensure no duplication of work.
Several
Worker
s monitor the index queue (up to 128) and wait for new jobs that are available to lease.Once a suitable job is found, the worker acquires a lease on the job and reads the relevant events from FDB and the blob store.
Depending on the indexing type, the job will be processed in one of a number of ways, and then marked as completed or returned for retries.
In this case, the event is also forwarded to CF Pipelines.
Trying it out
The first attempt did not go well. I found a bug in the high-contention indexer that led to frequent transaction conflicts. This was easily solved by correcting an incorrectly set parameter.
We also found there were other issues in the indexer, such as an insufficient amount of threads, and a suspicious decrease in the speed of the
Queuer
during processing of queued jobs.Along with fixing these issues, I also implemented other optimizations, such as deprioritizing
Worker
DB accesses, and increasing the batch size.To fix the degraded
Queuer
performance, I ran the backfill job by itself, and then started indexing after it had completed.Bottlenecks, bottlenecks everywhere
After implementing these fixes, there was an interesting problem: The DB couldn't go over 80K reads per second. I had encountered this limit during load testing for the scraper and other FDB benchmarks.
As I suspected, this was a client thread limitation, as one thread seemed to be using high amounts of CPU. To overcome this, I created a new client instance for each
Worker
.After investigating, I discovered that the Go FoundationDB client cached the database connection. This meant all attempts to create separate DB connections ended up being useless.
Using
OpenWithConnectionString
partially resolved this issue. (This also had benefits for service-discovery based connection configuration.)To be able to fully support multi-threading, I needed to enabled the FDB multi-client feature. Enabling it also allowed easier upgrades across DB versions, as FDB clients are incompatible across versions:
FDB_NETWORK_OPTION_EXTERNAL_CLIENT_LIBRARY="/lib/libfdb_c.so"
FDB_NETWORK_OPTION_CLIENT_THREADS_PER_VERSION="16"
Breaking the 100K/s reads barrier
After implementing support for the multi-threaded client, we were able to get over 100K reads per second.
You may notice after the restart (gap) the performance dropped. This was caused by several bugs: 1. When creating the CF Pipelines endpoint, we did not specify a region. The automatically selected region was far away from the server. 2. The amount of shards were not sufficient, so we increased them. 3. The client overloaded a few HTTP/2 connections with too many requests.
I implemented a feature to assign each
Worker
its own HTTP client, fixing the 3rd issue. We also moved the entire storage region to West Europe to be closer to the servers.After these changes, we were able to easily push over 200K reads/s, mostly limited by missing optimizations:
It's shards all the way down
While testing, we also noticed another issue: At certain times, a pipeline would get overloaded, stalling requests for seconds at a time. This prevented all forward progress on the
Worker
s.We solved this by having multiple pipelines: A primary pipeline meant to be for standard load, with moderate batching duration and less shards, and high-throughput pipelines with more shards.
Each
Worker
is assigned a pipeline on startup, and if one pipeline stalls, other workers can continue making progress and saturate the DB.The stress test
After making sure everything was ready for the import, we cleared all data, and started the import.
The entire import lasted 20 minutes between 01:44 UTC and 02:04 UTC, reaching a peak of: - 0.25M requests per second - 0.6M keys read per second - 140MB/s reads from DB - 2Gbps of network throughput
FoundationDB ran smoothly during this test, with: - Read times under 2ms - Zero conflicting transactions - No overloaded servers
CF Pipelines held up well, delivering batches to R2 without any issues, while reaching its maximum possible throughput.
Finishing notes
Me and Fishcake have been building infrastructure around scaling Nostr, from media, to relays, to content indexing. We consistently work on improving scalability, resiliency and stability, even outside these posts.
Many things, including what you see here, are already a part of Nostr.build, Noswhere and NFDB, and many other changes are being implemented every day.
If you like what you are seeing, and want to integrate it, get in touch. :)

2025-04-02 12:12:12We value sovereignty, privacy and security when accessing online content, using several tools to achieve this, like open protocols, open OSes, open software products, Tor and VPNs.
The problem
Talking about our social presence, we can manually build up our follower list (social graph), pick a Nostr client that is respectful of our preferences on what to show and how, but with the standard following mechanism, our main feed is public, so everyone can actually snoop what we are interested in, and what is supposable that we read daily.
The solution
Nostr has a simple solution for this necessity: encrypted lists. Lists are what they appear, a collection of people or interests (but they can also group much other stuff, see NIP-51). So we can create lists with contacts that we don't have in our main social graph; these lists can be used primarily to create dedicated feeds, but they could have other uses, for example, related to monitoring. The interesting thing about lists is that they can also be encrypted, so unlike the basic following list, which is always public, we can hide the lists' content from others. The implications are obvious: we can not only have a more organized way to browse content, but it is also really private one.
One might wonder what use can really be made of private lists; here are some examples:
- Browse “can't miss” content from users I consider a priority;
- Supervise competitors or adversarial parts;
- Monitor sensible topics (tags);
- Following someone without being publicly associated with them, as this may be undesirable;
The benefits in terms of privacy as usual are not only related to the casual, or programmatic, observer, but are also evident when we think of how many bots scan our actions to profile us.
The current state
Unfortunately, lists are not widely supported by Nostr clients, and encrypted support is a rarity. Often the excuse to not implement them is that they are harder to develop, since they require managing the encryption stuff (NIP-44). Nevertheless, developers have an easier option to start offering private lists: give the user the possibility to simply mark them as local-only, and never push them to the relays. Even if the user misses the sync feature, this is sufficient to create a private environment.
To date, as far as I know, the best client with list management is Gossip, which permits to manage both encrypted and local-only lists.
Beg your Nostr client to implement private lists!

2025-05-27 12:01:36Donald Trump’s recent four-day visit took the President to Saudi Arabia, Qatar, and the United Arab Emirates. This visit has intertwined diplomatic relations with business interests, while simultaneously influencing the bitcoin market.
In Qatar, the President met with Emir Tanim bin Hamad Al Thani, resulting in over $243 billion in deals including major defense agreements, according to Bloomberg.
On May 15, the President made his visit to the Sheikh Zayed Grand Mosque in Abu Dhabi alongside Crown Prince Khaled bin Mohamed Al Nahyan. This occurs as the Trump family expands its business presence in the Middle East.
The Trump Organization is developing luxury properties across the region, including Trump Tower Dubai, real estate projects in Riyadh, and development in Jeddah and Oman.
Donald Trump and Mohammed bin Salman in King Khalid International Airport — NBCNews
Eric Trump publicly announced construction plans for Trump Tower Dubai just last month, highlighting the family’s ongoing commercial footprint in the region.
These business connections extend into the digital asset ecosystem as UAE-backed investment firm MGX recently announced it would use USD1, World Liberty Financial’s stablecoin to support a $2 billion investment in Binance, the world’s largest digital asset exchange, according to APNews.
This connection between Trump-aligned interests and major digital asset investments creates a potential avenue for market influence.
Historically, stability in the Middle East, especially among oil-rich nations, reduces global market volatility. This encourages risk appetite among investors, often leading to increased allocations to digital assets like bitcoin.
Middle East diplomacy directly affects global oil prices. Stable oil prices can lower inflation expectations and lead to interest rate cuts by the Fed. Lower rates lead to an increase in liquidity, having positive effects on bitcoin, an asset that benefits from money printing.
Related: Fed Rate Cuts Could Lead to Major Price Swings for Bitcoin
On the investment front, Abu Dhabi’s Wealth Fund, Mubadala Investment Company, has been focused on increasing their shares in BlackRock’s iShares Bitcoin Trust (IBIT).
According to a 13F filing with the U.S. Securities and Exchange Commission, Mubdala held 8.7 million IBIT shares, totaling $408.5 million as of March 31, 2025.
The Abu Dhabi Wealth Fund increased its shares by 500,000 since its last filing in December of 2024.
Back in March, the United States created a Strategic Bitcoin Reserve. The executive order states that the U.S. will not sell the bitcoin they already hold, and will create budget-neutral ways to increase their holdings.
The time has come where governments and wealth funds alike are jumping on board the Bitcoin train.
Trump’s recent visit to the Middle East illustrates how financial, diplomatic, and personal interests are becoming increasingly intertwined with Bitcoin and digital assets, serving as a new axis of influence in the U.S.-Middle East relations.
The combination of diplomatic progress and business expansion has heightened short-term volatility and trading volumes in the bitcoin market.
Trump’s business and digital asset ties in the region may further boost institutional interest and create an opportunity for more players to enter the market.

2025-05-27 11:27:26Since its creation, Bitcoin has been a revolutionary asset, challenging the traditional financial system and proposing a new form of decentralized money. However, its future remains uncertain and the subject of intense debate. Among the possible outcomes, two extreme scenarios stand out: hyperbitcoinization-where Bitcoin becomes the dominant currency in the global economy—and obsolescence, where the network loses relevance and is replaced by other solutions.
- Hyperbitcoinization: The World Adopts Bitcoin as a Monetary Standard
01 - Loss of trust in fiat currencies: Due to excessive money printing by central banks, many economies face rampant inflation. Bitcoin, with its fixed supply of 21 million units, emerges as a more trustworthy alternative.
02 - Growing adoption by companies and governments: Some countries have already begun integrating Bitcoin into their economies, accepting it for payments and as a store of value. If this trend continues, Bitcoin’s legitimacy as a global currency will grow.
03 - Ease of global transactions: Bitcoin enables fast and low-cost international transfers, removing the need for financial intermediaries and reducing operational costs.
04 - Technological advancements: Scalability improvements, such as the Lightning Network, can make Bitcoin more efficient for daily use, encouraging mass adoption.
If hyperbitcoinization becomes reality, the world may witness a radical shift in the financial system—with greater decentralization, censorship resistance, and an economy based on sound, predictable money.
- Obsolescence: Bitcoin Loses Relevance and Is Replaced
01 - Restrictive government regulations: If major economic powers enforce strict regulations on Bitcoin, adoption could slow, reducing its utility.
02 - Technological shortcomings or lack of innovation: Despite its security and decentralization, Bitcoin may struggle to scale effectively. If superior solutions emerge and gain acceptance, Bitcoin could lose its leading position.
03 - Competition from faster, more user-friendly alternatives: Other forms of digital money may surpass Bitcoin in scalability and usability, potentially leading to a decline in Bitcoin adoption.
04 - Decreasing miner incentives: As new Bitcoin issuance halves every four years, miners will rely increasingly on transaction fees. If those fees are insufficient to sustain network security, long-term viability could be at risk.
In summary, Bitcoin’s future could unfold along multiple paths, depending on factors like innovation, global adoption, and resilience to external challenges. Hyperbitcoinization would represent an economic revolution—ushering in a decentralized, inflation-resistant monetary system. Yet, obsolescence remains a risk if the network fails to adapt to future demands. Regardless of the outcome, Bitcoin has already made its mark on financial history, paving the way for a new era of digital money and economic freedom.
Thank you very much for reading this far. I hope everything is well with you, and sending a big hug from your favorite Bitcoiner maximalist from Madeira. Long live freedom!

2025-05-27 12:01:34Bahrain-based Al Abraaj Restaurants Group has made history by becoming the first publicly-traded company in the Middle East to add bitcoin to its corporate treasury. This is a major step forward for regional bitcoin adoption.
On May 15, 2025, Al Abraaj Restaurants Group, a well-known restaurant chain listed on the Bahrain Bourse, announced it had bought 5 bitcoin (BTC) as part of a new treasury strategy. This makes the company the first in Bahrain, the GCC and the Middle East to officially hold bitcoin as a reserve asset.
Al Abraaj adds bitcoin to its treasury — Zawya
This is a growing trend globally where companies are treating bitcoin not just as an investment but as a long-term store of value. Major companies like Strategy, Tesla and Metaplanet have already done this — and now Al Abraaj is following suit.
Metaplanet recently added 1,241 BTC to its treasury, boosting the company’s holdings above El Salvador’s.

“Our initiative towards becoming a Bitcoin Treasury Company reflects our forward-thinking approach and dedication to maximizing shareholder value,” said Abdulla Isa, Chairman of the Bitcoin Treasury Committee at Al Abraaj.
Al Abraaj’s move is largely inspired by Michael Saylor, Executive Chairman of Strategy, the world’s largest corporate holder of bitcoin. Saylor’s strategy of allocating billions to bitcoin has set a model that other companies — now including Al Abraaj — are following.
A photo shared by the company even showed a meeting between an Al Abraaj representative and Saylor, with the company calling itself the “MicroStrategy of the Middle East”.
“We believe that Bitcoin will play a pivotal role in the future of finance, and we are excited to be at the forefront of this transformation in the Kingdom of Bahrain,” Isa added.
To support its bitcoin initiative, Al Abraaj has partnered with 10X Capital, a New York-based investment firm that specializes in digital assets.
10X Capital has a strong track record in bitcoin treasury strategies, and recently advised Nakamoto Holdings on a $710 million deal — the largest of its kind.
With 10X’s help, Al Abraaj looks to raise more capital and increase its bitcoin holdings over time to maximize bitcoin-per-share for its investors. The company will also develop Sharia-compliant financial instruments so Islamic investors can get exposure to bitcoin in a halal way.
“Bahrain continues to be a leader in the Middle East in Bitcoin adoption,” said Hans Thomas, CEO of 10X Capital. He noted, with a combined GDP of $2.2 trillion and over $6 trillion in sovereign wealth, the GCC now has its first publicly listed bitcoin treasury company.
This is not just a first for Al Abraaj — it’s a first for the region. Bahrain has been positioning itself as a fintech hub and Al Abraaj’s move will encourage more non-fintech companies in the region to look into bitcoin.
The company said the decision was made after thorough due diligence and is in line with the regulations set by the Central Bank of Bahrain (CBB). Al Abraaj will be fully compliant with all digital asset transaction rules, including transparency, security and governance.
A special Bitcoin Committee has been formed to oversee the treasury strategy. It includes experienced bitcoin investors, financial experts and portfolio managers who will manage risk, monitor market conditions and ensure best practices in custody and disclosure.
The initial purchase was 5 BTC, but Al Abraaj sees this as just the beginning. The company stated that there are plans in motion to allocate a significant portion of their treasury into bitcoin over time.
According to the company’s reports, Al Abraaj is financially sound with $12.5 million in EBITDA in 2024. This strong financial foundation gives the company the confidence to explore new strategies like bitcoin investment.

2025-05-27 09:21:51Know Your Customer is a regulation that requires companies of all sizes to verify the identity, suitability, and risks involved with maintaining a business relationship with a customer. Such procedures fit within the broader scope of anti-money laundering (AML) and counterterrorism financing (CTF) regulations.
Banks, exchanges, online business, mail providers, domain registrars... Everyone wants to know who you are before you can even opt for their service. Your personal information is flowing around the internet in the hands of "god-knows-who" and secured by "trust-me-bro military-grade encryption". Once your account is linked to your personal (and verified) identity, tracking you is just as easy as keeping logs on all these platforms.
Rights for Illusions
KYC processes aim to combat terrorist financing, money laundering, and other illicit activities. On the surface, KYC seems like a commendable initiative. I mean, who wouldn't want to halt terrorists and criminals in their tracks?
The logic behind KYC is: "If we mandate every financial service provider to identify their users, it becomes easier to pinpoint and apprehend the malicious actors."
However, terrorists and criminals are not precisely lining up to be identified. They're crafty. They may adopt false identities or find alternative strategies to continue their operations. Far from being outwitted, many times they're several steps ahead of regulations. Realistically, KYC might deter a small fraction – let's say about 1% ^1 – of these malefactors. Yet, the cost? All of us are saddled with the inconvenient process of identification just to use a service.
Under the rhetoric of "ensuring our safety", governments and institutions enact regulations that seem more out of a dystopian novel, gradually taking away our right to privacy.
To illustrate, consider a city where the mayor has rolled out facial recognition cameras in every nook and cranny. A band of criminals, intent on robbing a local store, rolls in with a stolen car, their faces obscured by masks and their bodies cloaked in all-black clothes. Once they've committed the crime and exited the city's boundaries, they switch vehicles and clothes out of the cameras' watchful eyes. The high-tech surveillance? It didn’t manage to identify or trace them. Yet, for every law-abiding citizen who merely wants to drive through the city or do some shopping, their movements and identities are constantly logged. The irony? This invasive tracking impacts all of us, just to catch the 1% ^1 of less-than-careful criminals.
KYC? Not you.
KYC creates barriers to participation in normal economic activity, to supposedly stop criminals. ^2
KYC puts barriers between many users and businesses. One of these comes from the fact that the process often requires multiple forms of identification, proof of address, and sometimes even financial records. For individuals in areas with poor record-keeping, non-recognized legal documents, or those who are unbanked, homeless or transient, obtaining these documents can be challenging, if not impossible.
For people who are not skilled with technology or just don't have access to it, there's also a barrier since KYC procedures are mostly online, leaving them inadvertently excluded.
Another barrier goes for the casual or one-time user, where they might not see the value in undergoing a rigorous KYC process, and these requirements can deter them from using the service altogether.
It also wipes some businesses out of the equation, since for smaller businesses, the costs associated with complying with KYC norms—from the actual process of gathering and submitting documents to potential delays in operations—can be prohibitive in economical and/or technical terms.
You're not welcome
Imagine a swanky new club in town with a strict "members only" sign. You hear the music, you see the lights, and you want in. You step up, ready to join, but suddenly there's a long list of criteria you must meet. After some time, you are finally checking all the boxes. But then the club rejects your membership with no clear reason why. You just weren't accepted. Frustrating, right?
This club scenario isn't too different from the fact that KYC is being used by many businesses as a convenient gatekeeping tool. A perfect excuse based on a "legal" procedure they are obliged to.
Even some exchanges may randomly use this to freeze and block funds from users, claiming these were "flagged" by a cryptic system that inspects the transactions. You are left hostage to their arbitrary decision to let you successfully pass the KYC procedure. If you choose to sidestep their invasive process, they might just hold onto your funds indefinitely.
Your identity has been stolen
KYC data has been found to be for sale on many dark net markets^3. Exchanges may have leaks or hacks, and such leaks contain very sensitive data. We're talking about the full monty: passport or ID scans, proof of address, and even those awkward selfies where you're holding up your ID next to your face. All this data is being left to the mercy of the (mostly) "trust-me-bro" security systems of such companies. Quite scary, isn't it?
As cheap as $10 for 100 documents, with discounts applying for those who buy in bulk, the personal identities of innocent users who passed KYC procedures are for sale. ^3
In short, if you have ever passed the KYC/AML process of a crypto exchange, your privacy is at risk of being compromised, or it might even have already been compromised.
(they) Know Your Coins
You may already know that Bitcoin and most cryptocurrencies have a transparent public blockchain, meaning that all data is shown unencrypted for everyone to see and recorded forever. If you link an address you own to your identity through KYC, for example, by sending an amount from a KYC exchange to it, your Bitcoin is no longer pseudonymous and can then be traced.
If, for instance, you send Bitcoin from such an identified address to another KYC'ed address (say, from a friend), everyone having access to that address-identity link information (exchanges, governments, hackers, etc.) will be able to associate that transaction and know who you are transacting with.
Conclusions
To sum up, KYC does not protect individuals; rather, it's a threat to our privacy, freedom, security and integrity. Sensible information flowing through the internet is thrown into chaos by dubious security measures. It puts borders between many potential customers and businesses, and it helps governments and companies track innocent users. That's the chaos KYC has stirred.
The criminals are using stolen identities from companies that gathered them thanks to these very same regulations that were supposed to combat them. Criminals always know how to circumvent such regulations. In the end, normal people are the most affected by these policies.
The threat that KYC poses to individuals in terms of privacy, security and freedom is not to be neglected. And if we don’t start challenging these systems and questioning their efficacy, we are just one step closer to the dystopian future that is now foreseeable.
Edited 20/03/2024 * Add reference to the 1% statement on Rights for Illusions section to an article where Chainalysis found that only 0.34% of the transaction volume with cryptocurrencies in 2023 was attributable to criminal activity ^1

2025-05-27 11:22:10Since its creation, Bitcoin has been much more than just an alternative to traditional money. With the ongoing digitalization of the global economy, Bitcoin has emerged as a foundational pillar for new forms of transactions, commerce, and value storage. Its decentralization, transparency, and censorship resistance make it a solid base for digital economies, where financial interactions occur without the need for traditional intermediaries.
- Bitcoin’s role in the digital economy
01 - Global, borderless transactions: Anyone with internet access can send and receive Bitcoin without needing a bank or government authorization.
02 - Limited and predictable supply: Unlike fiat currencies that can be inflated by central banks, Bitcoin has a fixed cap of 21 million units, making it a scarce and reliable asset.
03 - Security and transparency: The Bitcoin blockchain or timechain publicly records all transactions, ensuring a secure and auditable system.
04 - Censorship resistance: No government or institution can block Bitcoin transactions, enabling a freer and more accessible digital economy.
With these characteristics, Bitcoin is already transforming various economic sectors and driving new forms of commerce and investment.
- Bitcoin in digital commerce and the global economy
01 - E-commerce: Businesses and consumers can use Bitcoin for fast international transactions without exorbitant fees.
02 - International remittances: Workers sending money to their home countries can avoid high fees and long delays by using Bitcoin.
03 - Emerging economies: In countries with unstable currencies and unreliable banking systems, Bitcoin serves as a secure and decentralized alternative for storing wealth and conducting daily transactions.
Additionally, Bitcoin is being adopted by companies and even governments as a store of value, reinforcing its role as a foundation for the digital economy of the future.
- Challenges and adapting to the new economy
01 - Price volatility: Bitcoin’s fluctuating value can make it difficult to use as a daily medium of exchange.
02 - Regulations and governmental resistance: Some countries attempt to restrict or regulate Bitcoin to maintain control over the traditional financial system.
03 - Education and adoption: Many people still lack the knowledge to use Bitcoin safely and effectively.
In summary, Bitcoin is transforming the way the world interacts with money, offering a decentralized and transparent alternative for digital economies. As more individuals and businesses adopt Bitcoin for payments, savings, and global commerce, its impact becomes increasingly clear. Despite the challenges, Bitcoin continues to solidify its place as the foundation of a new economic paradigm—where financial freedom and technological innovation go hand in hand.
Thank you very much for reading this far. I hope everything is well with you, and sending a big hug from your favorite Bitcoiner maximalist from Madeira. Long live freedom!

2025-05-27 09:21:50Over the past few months, I've dedicated my time to a complete rewrite of the kycnot.me website. The technology stack remains unchanged; Golang paired with TailwindCSS. However, I've made some design choices in this iteration that I believe significantly enhance the site. Particularly to backend code.
UI Improvements
You'll notice a refreshed UI that retains the original concept but has some notable enhancements. The service list view is now more visually engaging, it displays additional information in a more aesthetically pleasing manner. Both filtering and searching functionalities have been optimized for speed and user experience.
Service pages have been also redesigned to highlight key information at the top, with the KYC Level box always accessible. The display of service attributes is now more visually intuitive.
The request form, especially the Captcha, has undergone substantial improvements. The new self-made Captcha is robust, addressing the reliability issues encountered with the previous version.
Terms of Service Summarizer
A significant upgrade is the Terms of Service summarizer/reviewer, now powered by AI (GPT-4-turbo). It efficiently condenses each service's ToS, extracting and presenting critical points, including any warnings. Summaries are updated monthly, processing over 40 ToS pages via the OpenAI API using a self-crafted and thoroughly tested prompt.
Nostr Comments
I've integrated a comment section for each service using Nostr. For guidance on using this feature, visit the dedicated how-to page.
Database
The backend database has transitioned to pocketbase, an open-source Golang backend that has been a pleasure to work with. I maintain an updated fork of the Golang SDK for pocketbase at pluja/pocketbase.
Scoring
The scoring algorithm has also been refined to be more fair. Despite I had considered its removal due to the complexity it adds (it is very difficult to design a fair scoring system), some users highlighted its value, so I kept it. The updated algorithm is available open source.
Listings
Each listing has been re-evaluated, and the ones that were no longer operational were removed. New additions are included, and the backlog of pending services will be addressed progressively, since I still have access to the old database.
API
The API now offers more comprehensive data. For more details, check here.
About Page
The About page has been restructured for brevity and clarity.
Other Changes
Extensive changes have been implemented in the server-side logic, since the whole code base was re-written from the ground up. I may discuss these in a future post, but for now, I consider the current version to be just a bit beyond beta, and additional updates are planned in the coming weeks.

@ c066aac5:6a41a034
2025-04-05 16:58:58I’m drawn to extremities in art. The louder, the bolder, the more outrageous, the better. Bold art takes me out of the mundane into a whole new world where anything and everything is possible. Having grown up in the safety of the suburban midwest, I was a bit of a rebellious soul in search of the satiation that only came from the consumption of the outrageous. My inclination to find bold art draws me to NOSTR, because I believe NOSTR can be the place where the next generation of artistic pioneers go to express themselves. I also believe that as much as we are able, were should invite them to come create here.
My Background: A Small Side Story
My father was a professional gamer in the 80s, back when there was no money or glory in the avocation. He did get a bit of spotlight though after the fact: in the mid 2000’s there were a few parties making documentaries about that era of gaming as well as current arcade events (namely 2007’sChasing GhostsandThe King of Kong: A Fistful of Quarters). As a result of these documentaries, there was a revival in the arcade gaming scene. My family attended events related to the documentaries or arcade gaming and I became exposed to a lot of things I wouldn’t have been able to find. The producer ofThe King of Kong: A Fistful of Quarters had previously made a documentary calledNew York Dollwhich was centered around the life of bassist Arthur Kane. My 12 year old mind was blown: The New York Dolls were a glam-punk sensation dressed in drag. The music was from another planet. Johnny Thunders’ guitar playing was like Chuck Berry with more distortion and less filter. Later on I got to meet the Galaga record holder at the time, Phil Day, in Ottumwa Iowa. Phil is an Australian man of high intellect and good taste. He exposed me to great creators such as Nick Cave & The Bad Seeds, Shakespeare, Lou Reed, artists who created things that I had previously found inconceivable.
I believe this time period informed my current tastes and interests, but regrettably I think it also put coals on the fire of rebellion within. I stopped taking my parents and siblings seriously, the Christian faith of my family (which I now hold dearly to) seemed like a mundane sham, and I felt I couldn’t fit in with most people because of my avant-garde tastes. So I write this with the caveat that there should be a way to encourage these tastes in children without letting them walk down the wrong path. There is nothing inherently wrong with bold art, but I’d advise parents to carefully find ways to cultivate their children’s tastes without completely shutting them down and pushing them away as a result. My parents were very loving and patient during this time; I thank God for that.
With that out of the way, lets dive in to some bold artists:
Nicolas Cage: Actor
There is an excellent video by Wisecrack on Nicolas Cage that explains him better than I will, which I will linkhere. Nicolas Cage rejects the idea that good acting is tied to mere realism; all of his larger than life acting decisions are deliberate choices. When that clicked for me, I immediately realized the man is a genius. He borrows from Kabuki and German Expressionism, art forms that rely on exaggeration to get the message across. He has even created his own acting style, which he calls Nouveau Shamanic. He augments his imagination to go from acting to being. Rather than using the old hat of method acting, he transports himself to a new world mentally. The projects he chooses to partake in are based on his own interests or what he considers would be a challenge (making a bad script good for example). Thus it doesn’t matter how the end result comes out; he has already achieved his goal as an artist. Because of this and because certain directors don’t know how to use his talents, he has a noticeable amount of duds in his filmography. Dig around the duds, you’ll find some pure gold. I’d personally recommend the filmsPig, Joe, Renfield, and his Christmas film The Family Man.
Nick Cave: Songwriter
What a wild career this man has had! From the apocalyptic mayhem of his band The Birthday Party to the pensive atmosphere of his albumGhosteen, it seems like Nick Cave has tried everything. I think his secret sauce is that he’s always working. He maintains an excellent newsletter calledThe Red Hand Files, he has written screenplays such asLawless, he has written books, he has made great film scores such asThe Assassination of Jesse James by the Coward Robert Ford, the man is religiously prolific. I believe that one of the reasons he is prolific is that he’s not afraid to experiment. If he has an idea, he follows it through to completion. From the albumMurder Ballads(which is comprised of what the title suggests) to his rejected sequel toGladiator(Gladiator: Christ Killer), he doesn’t seem to be afraid to take anything on. This has led to some over the top works as well as some deeply personal works. Albums likeSkeleton TreeandGhosteenwere journeys through the grief of his son’s death. The Boatman’s Callis arguably a better break-up album than anything Taylor Swift has put out. He’s not afraid to be outrageous, he’s not afraid to offend, but most importantly he’s not afraid to be himself. Works I’d recommend include The Birthday Party’sLive 1981-82, Nick Cave & The Bad Seeds’The Boatman’s Call, and the filmLawless.
Jim Jarmusch: Director
I consider Jim’s films to be bold almost in an ironic sense: his works are bold in that they are, for the most part, anti-sensational. He has a rule that if his screenplays are criticized for a lack of action, he makes them even less eventful. Even with sensational settings his films feel very close to reality, and they demonstrate the beauty of everyday life. That's what is bold about his art to me: making the sensational grounded in reality while making everyday reality all the more special. Ghost Dog: The Way of the Samurai is about a modern-day African-American hitman who strictly follows the rules of the ancient Samurai, yet one can resonate with the humanity of a seemingly absurd character. Only Lovers Left Aliveis a vampire love story, but in the middle of a vampire romance one can see their their own relationships in a new deeply human light. Jim’s work reminds me that art reflects life, and that there is sacred beauty in seemingly mundane everyday life. I personally recommend his filmsPaterson,Down by Law, andCoffee and Cigarettes.
NOSTR: We Need Bold Art
NOSTR is in my opinion a path to a better future. In a world creeping slowly towards everything apps, I hope that the protocol where the individual owns their data wins over everything else. I love freedom and sovereignty. If NOSTR is going to win the race of everything apps, we need more than Bitcoin content. We need more than shirtless bros paying for bananas in foreign countries and exercising with girls who have seductive accents. Common people cannot see themselves in such a world. NOSTR needs to catch the attention of everyday people. I don’t believe that this can be accomplished merely by introducing more broadly relevant content; people are searching for content that speaks to them. I believe that NOSTR can and should attract artists of all kinds because NOSTR is one of the few places on the internet where artists can express themselves fearlessly. Getting zaps from NOSTR’s value-for-value ecosystem has far less friction than crowdfunding a creative project or pitching investors that will irreversibly modify an artist’s vision. Having a place where one can post their works without fear of censorship should be extremely enticing. Having a place where one can connect with fellow humans directly as opposed to a sea of bots should seem like the obvious solution. If NOSTR can become a safe haven for artists to express themselves and spread their work, I believe that everyday people will follow. The banker whose stressful job weighs on them will suddenly find joy with an original meme made by a great visual comedian. The programmer for a healthcare company who is drowning in hopeless mundanity could suddenly find a new lust for life by hearing the song of a musician who isn’t afraid to crowdfund their their next project by putting their lighting address on the streets of the internet. The excel guru who loves independent film may find that NOSTR is the best way to support non corporate movies. My closing statement: continue to encourage the artists in your life as I’m sure you have been, but while you’re at it give them the purple pill. You may very well be a part of building a better future.

2025-05-27 09:21:48I'm launching a new service review section on this blog in collaboration with OrangeFren. These reviews are sponsored, yet the sponsorship does not influence the outcome of the evaluations. Reviews are done in advance, then, the service provider has the discretion to approve publication without modifications.
Sponsored reviews are independent from the kycnot.me list, being only part of the blog. The reviews have no impact on the scores of the listings or their continued presence on the list. Should any issues arise, I will not hesitate to remove any listing.
The review
WizardSwap is an instant exchange centred around privacy coins. It was launched in 2020 making it old enough to have weathered the 2021 bull run and the subsequent bearish year.
| Pros | Cons | |------|------| | Tor-friendly | Limited liquidity | | Guarantee of no KYC | Overly simplistic design | | Earn by providing liquidity | |
Rating: ★★★★★ Service Website: wizardswap.io
Liquidity
Right off the bat, we'll start off by pointing out that WizardSwap relies on its own liquidity reserves, meaning they aren't just a reseller of Binance or another exchange. They're also committed to a no-KYC policy, when asking them, they even promised they would rather refund a user their original coins, than force them to undergo any sort of verification.
On the one hand, full control over all their infrastructure gives users the most privacy and conviction about the KYC policies remaining in place.
On the other hand, this means the liquidity available for swapping isn't huge. At the time of testing we could only purchase at most about 0.73 BTC with XMR.
It's clear the team behind WizardSwap is aware of this shortfall and so they've come up with a solution unique among instant exchanges. They let you, the user, deposit any of the currencies they support into your account and earn a profit on the trades made using your liquidity.
Trading
Fees on WizardSwap are middle-of-the-pack. The normal fee is 2.2%. That's more than some exchanges that reserve the right to suddenly demand you undergo verification, yet less than half the fees on some other privacy-first exchanges. However as we mentioned in the section above you can earn almost all of that fee (2%) if you provide liquidity to WizardSwap.
It's good that with the current Bitcoin fee market their fees are constant regardless of how much, or how little, you send. This is in stark contrast with some of the alternative swap providers that will charge you a massive premium when attempting to swap small amounts of BTC away.
Test trades
Test trades are always performed without previous notice to the service provider.
During our testing we performed a few test trades and found that every single time WizardSwap immediately detected the incoming transaction and the amount we received was exactly what was quoted before depositing. The fees were inline with what WizardSwap advertises.
- Monero payment proof
- Bitcoin received
- Wizardswap TX link - it's possible that this link may cease to be valid at some point in the future.
ToS and KYC
WizardSwap does not have a Terms of Service or a Privacy Policy page, at least none that can be found by users. Instead, they offer a FAQ section where they addresses some basic questions.
The site does not mention any KYC or AML practices. It also does not specify how refunds are handled in case of failure. However, based on the FAQ section "What if I send funds after the offer expires?" it can be inferred that contacting support is necessary and network fees will be deducted from any refund.
UI & Tor
WizardSwap can be visited both via your usual browser and Tor Browser. Should you decide on the latter you'll find that the website works even with the most strict settings available in the Tor Browser (meaning no JavaScript).
However, when disabling Javascript you'll miss the live support chat, as well as automatic refreshing of the trade page. The lack of the first means that you will have no way to contact support from the trade page if anything goes wrong during your swap, although you can do so by mail.
One important thing to have in mind is that if you were to accidentally close the browser during the swap, and you did not save the swap ID or your browser history is disabled, you'll have no easy way to return to the trade. For this reason we suggest when you begin a trade to copy the url or ID to someplace safe, before sending any coins to WizardSwap.
The UI you'll be greeted by is simple, minimalist, and easy to navigate. It works well not just across browsers, but also across devices. You won't have any issues using this exchange on your phone.
Getting in touch
The team behind WizardSwap appears to be most active on X (formerly Twitter): https://twitter.com/WizardSwap_io
If you have any comments or suggestions about the exchange make sure to reach out to them. In the past they've been very receptive to user feedback, for instance a few months back WizardSwap was planning on removing DeepOnion, but the community behind that project got together ^1 and after reaching out WizardSwap reversed their decision ^2.
You can also contact them via email at:

@ 04c915da:3dfbecc9
2025-03-10 23:31:30Bitcoin has always been rooted in freedom and resistance to authority. I get that many of you are conflicted about the US Government stacking but by design we cannot stop anyone from using bitcoin. Many have asked me for my thoughts on the matter, so let’s rip it.
Concern
One of the most glaring issues with the strategic bitcoin reserve is its foundation, built on stolen bitcoin. For those of us who value private property this is an obvious betrayal of our core principles. Rather than proof of work, the bitcoin that seeds this reserve has been taken by force. The US Government should return the bitcoin stolen from Bitfinex and the Silk Road.
Usually stolen bitcoin for the reserve creates a perverse incentive. If governments see a bitcoin as a valuable asset, they will ramp up efforts to confiscate more bitcoin. The precedent is a major concern, and I stand strongly against it, but it should be also noted that governments were already seizing coin before the reserve so this is not really a change in policy.
Ideally all seized bitcoin should be burned, by law. This would align incentives properly and make it less likely for the government to actively increase coin seizures. Due to the truly scarce properties of bitcoin, all burned bitcoin helps existing holders through increased purchasing power regardless. This change would be unlikely but those of us in policy circles should push for it regardless. It would be best case scenario for American bitcoiners and would create a strong foundation for the next century of American leadership.
Optimism
The entire point of bitcoin is that we can spend or save it without permission. That said, it is a massive benefit to not have one of the strongest governments in human history actively trying to ruin our lives.
Since the beginning, bitcoiners have faced horrible regulatory trends. KYC, surveillance, and legal cases have made using bitcoin and building bitcoin businesses incredibly difficult. It is incredibly important to note that over the past year that trend has reversed for the first time in a decade. A strategic bitcoin reserve is a key driver of this shift. By holding bitcoin, the strongest government in the world has signaled that it is not just a fringe technology but rather truly valuable, legitimate, and worth stacking.
This alignment of incentives changes everything. The US Government stacking proves bitcoin’s worth. The resulting purchasing power appreciation helps all of us who are holding coin and as bitcoin succeeds our government receives direct benefit. A beautiful positive feedback loop.
Realism
We are trending in the right direction. A strategic bitcoin reserve is a sign that the state sees bitcoin as an asset worth embracing rather than destroying. That said, there is a lot of work left to be done. We cannot be lulled into complacency, the time to push forward is now, and we cannot take our foot off the gas. We have a seat at the table for the first time ever. Let's make it worth it.
We must protect the right to free usage of bitcoin and other digital technologies. Freedom in the digital age must be taken and defended, through both technical and political avenues. Multiple privacy focused developers are facing long jail sentences for building tools that protect our freedom. These cases are not just legal battles. They are attacks on the soul of bitcoin. We need to rally behind them, fight for their freedom, and ensure the ethos of bitcoin survives this new era of government interest. The strategic reserve is a step in the right direction, but it is up to us to hold the line and shape the future.

2025-03-26 20:54:33Capitalism is the most effective system for scaling innovation. The pursuit of profit is an incredibly powerful human incentive. Most major improvements to human society and quality of life have resulted from this base incentive. Market competition often results in the best outcomes for all.
That said, some projects can never be monetized. They are open in nature and a business model would centralize control. Open protocols like bitcoin and nostr are not owned by anyone and if they were it would destroy the key value propositions they provide. No single entity can or should control their use. Anyone can build on them without permission.
As a result, open protocols must depend on donation based grant funding from the people and organizations that rely on them. This model works but it is slow and uncertain, a grind where sustainability is never fully reached but rather constantly sought. As someone who has been incredibly active in the open source grant funding space, I do not think people truly appreciate how difficult it is to raise charitable money and deploy it efficiently.
Projects that can be monetized should be. Profitability is a super power. When a business can generate revenue, it taps into a self sustaining cycle. Profit fuels growth and development while providing projects independence and agency. This flywheel effect is why companies like Google, Amazon, and Apple have scaled to global dominance. The profit incentive aligns human effort with efficiency. Businesses must innovate, cut waste, and deliver value to survive.
Contrast this with non monetized projects. Without profit, they lean on external support, which can dry up or shift with donor priorities. A profit driven model, on the other hand, is inherently leaner and more adaptable. It is not charity but survival. When survival is tied to delivering what people want, scale follows naturally.
The real magic happens when profitable, sustainable businesses are built on top of open protocols and software. Consider the many startups building on open source software stacks, such as Start9, Mempool, and Primal, offering premium services on top of the open source software they build out and maintain. Think of companies like Block or Strike, which leverage bitcoin’s open protocol to offer their services on top. These businesses amplify the open software and protocols they build on, driving adoption and improvement at a pace donations alone could never match.
When you combine open software and protocols with profit driven business the result are lean, sustainable companies that grow faster and serve more people than either could alone. Bitcoin’s network, for instance, benefits from businesses that profit off its existence, while nostr will expand as developers monetize apps built on the protocol.
Capitalism scales best because competition results in efficiency. Donation funded protocols and software lay the groundwork, while market driven businesses build on top. The profit incentive acts as a filter, ensuring resources flow to what works, while open systems keep the playing field accessible, empowering users and builders. Together, they create a flywheel of innovation, growth, and global benefit.

2025-05-26 18:28:46Imagine a world where your favorite health and fitness apps—diet trackers, meditation tools, cardio and strength training platforms, even therapy apps—can all work together seamlessly. Not because they're owned by the same company, but because they speak a common, open language. That's the future NIP-101h is building on Nostr.
A Modular, Privacy-First Health Data Framework
NIP-101h defines a modular, privacy-first framework for sharing granular health and fitness metrics on the decentralized Nostr protocol. The core idea is simple but powerful: every health metric (weight, steps, calories, mood, and so on) gets its own unique Nostr event kind. Apps can implement only the metrics they care about, and users can choose exactly what to share, with whom, and how.
This modular approach means true interoperability. A meditation app can log mindfulness sessions, a running app can record your daily mileage, and a diet tracker can keep tabs on your nutrition—all using the same underlying standard. Each app remains independent, but your data becomes portable, composable, and, most importantly, under your control.
Why NIP-101h Matters
Interoperability
Today's health and fitness apps are walled gardens. Data is locked away in proprietary formats, making it hard to move, analyze, or combine. NIP-101h breaks down these barriers by providing a common, open standard for health metrics on Nostr. Apps can collaborate, users can migrate, and new services can emerge—without permission or lock-in.
User Control & Privacy
Health data is deeply personal. That's why NIP-101h is privacy-first: all metric values are encrypted by default using NIP-44, unless the user explicitly opts out. You decide what's public, what's private, and who gets access. Even if you want to keep everything local, that's supported too.
Extensibility
The world of health and fitness is always evolving. NIP-101h is designed to grow with it. New metrics can be added at any time via the

2025-02-09 22:56:33A Cypherpunk's Manifesto by Eric Hughes
Privacy is necessary for an open society in the electronic age. Privacy is not secrecy. A private matter is something one doesn't want the whole world to know, but a secret matter is something one doesn't want anybody to know. Privacy is the power to selectively reveal oneself to the world.
If two parties have some sort of dealings, then each has a memory of their interaction. Each party can speak about their own memory of this; how could anyone prevent it? One could pass laws against it, but the freedom of speech, even more than privacy, is fundamental to an open society; we seek not to restrict any speech at all. If many parties speak together in the same forum, each can speak to all the others and aggregate together knowledge about individuals and other parties. The power of electronic communications has enabled such group speech, and it will not go away merely because we might want it to.
Since we desire privacy, we must ensure that each party to a transaction have knowledge only of that which is directly necessary for that transaction. Since any information can be spoken of, we must ensure that we reveal as little as possible. In most cases personal identity is not salient. When I purchase a magazine at a store and hand cash to the clerk, there is no need to know who I am. When I ask my electronic mail provider to send and receive messages, my provider need not know to whom I am speaking or what I am saying or what others are saying to me; my provider only need know how to get the message there and how much I owe them in fees. When my identity is revealed by the underlying mechanism of the transaction, I have no privacy. I cannot here selectively reveal myself; I must always reveal myself.
Therefore, privacy in an open society requires anonymous transaction systems. Until now, cash has been the primary such system. An anonymous transaction system is not a secret transaction system. An anonymous system empowers individuals to reveal their identity when desired and only when desired; this is the essence of privacy.
Privacy in an open society also requires cryptography. If I say something, I want it heard only by those for whom I intend it. If the content of my speech is available to the world, I have no privacy. To encrypt is to indicate the desire for privacy, and to encrypt with weak cryptography is to indicate not too much desire for privacy. Furthermore, to reveal one's identity with assurance when the default is anonymity requires the cryptographic signature.
We cannot expect governments, corporations, or other large, faceless organizations to grant us privacy out of their beneficence. It is to their advantage to speak of us, and we should expect that they will speak. To try to prevent their speech is to fight against the realities of information. Information does not just want to be free, it longs to be free. Information expands to fill the available storage space. Information is Rumor's younger, stronger cousin; Information is fleeter of foot, has more eyes, knows more, and understands less than Rumor.
We must defend our own privacy if we expect to have any. We must come together and create systems which allow anonymous transactions to take place. People have been defending their own privacy for centuries with whispers, darkness, envelopes, closed doors, secret handshakes, and couriers. The technologies of the past did not allow for strong privacy, but electronic technologies do.
We the Cypherpunks are dedicated to building anonymous systems. We are defending our privacy with cryptography, with anonymous mail forwarding systems, with digital signatures, and with electronic money.
Cypherpunks write code. We know that someone has to write software to defend privacy, and since we can't get privacy unless we all do, we're going to write it. We publish our code so that our fellow Cypherpunks may practice and play with it. Our code is free for all to use, worldwide. We don't much care if you don't approve of the software we write. We know that software can't be destroyed and that a widely dispersed system can't be shut down.
Cypherpunks deplore regulations on cryptography, for encryption is fundamentally a private act. The act of encryption, in fact, removes information from the public realm. Even laws against cryptography reach only so far as a nation's border and the arm of its violence. Cryptography will ineluctably spread over the whole globe, and with it the anonymous transactions systems that it makes possible.
For privacy to be widespread it must be part of a social contract. People must come and together deploy these systems for the common good. Privacy only extends so far as the cooperation of one's fellows in society. We the Cypherpunks seek your questions and your concerns and hope we may engage you so that we do not deceive ourselves. We will not, however, be moved out of our course because some may disagree with our goals.
The Cypherpunks are actively engaged in making the networks safer for privacy. Let us proceed together apace.
Onward.

2025-05-27 09:21:46Bitcoin enthusiasts frequently and correctly remark how much value it adds to Bitcoin not to have a face, a leader, or a central authority behind it. This particularity means there isn't a single person to exert control over, or a single human point of failure who could become corrupt or harmful to the project.
Because of this, it is said that no other coin can be equally valuable as Bitcoin in terms of decentralization and trustworthiness. Bitcoin is unique not just for being first, but also because of how the events behind its inception developed. This implies that, from Bitcoin onwards, any coin created would have been created by someone, consequently having an authority behind it. For this and some other reasons, some people refer to Bitcoin as "The Immaculate Conception".
While other coins may have their own unique features and advantages, they may not be able to replicate Bitcoin's community-driven nature. However, one other cryptocurrency shares a similar story of mystery behind its creation: Monero.
History of Monero
Bytecoin and CryptoNote
In March 2014, a Bitcointalk thread titled "Bytecoin. Secure, private, untraceable since 2012" was initiated by a user under the nickname "DStrange"^1^. DStrange presented Bytecoin (BCN) as a unique cryptocurrency, in operation since July 2012. Unlike Bitcoin, it employed a new algorithm known as CryptoNote.
DStrange apparently stumbled upon the Bytecoin website by chance while mining a dying bitcoin fork, and decided to create a thread on Bitcointalk^1^. This sparked curiosity among some users, who wondered how could Bytecoin remain unnoticed since its alleged launch in 2012 until then^2^.
Some time after, a user brought up the "CryptoNote v2.0" whitepaper for the first time, underlining its innovative features^4^. Authored by the pseudonymous Nicolas van Saberhagen in October 2013, the CryptoNote v2 whitepaper^5^ highlighted the traceability and privacy problems in Bitcoin. Saberhagen argued that these flaws could not be quickly fixed, suggesting it would be more efficient to start a new project rather than trying to patch the original^5^, an statement simmilar to the one from Satoshi Nakamoto^6^.
Checking with Saberhagen's digital signature, the release date of the whitepaper seemed correct, which would mean that Cryptonote (v1) was created in 2012^7^, although there's an important detail: "Signing time is from the clock on the signer's computer" ^9^.
Moreover, the whitepaper v1 contains a footnote link to a Bitcointalk post dated May 5, 2013^10^, making it impossible for the whitepaper to have been signed and released on December 12, 2012.
As the narrative developed, users discovered that a significant 80% portion of Bytecoin had been pre-mined^11^ and blockchain dates seemed to be faked to make it look like it had been operating since 2012, leading to controversy surrounding the project.
The origins of CryptoNote and Bytecoin remain mysterious, leaving suspicions of a possible scam attempt, although the whitepaper had a good amount of work and thought on it.
The fork
In April 2014, the Bitcointalk user
thankful_for_today
, who had also participated in the Bytecoin thread^12^, announced plans to launch a Bytecoin fork named Bitmonero^13^.The primary motivation behind this fork was "Because there is a number of technical and marketing issues I wanted to do differently. And also because I like ideas and technology and I want it to succeed"^14^. This time Bitmonero did things different from Bytecoin: there was no premine or instamine, and no portion of the block reward went to development.
However, thankful_for_today proposed controversial changes that the community disagreed with. Johnny Mnemonic relates the events surrounding Bitmonero and thankful_for_today in a Bitcointalk comment^15^:
When thankful_for_today launched BitMonero [...] he ignored everything that was discussed and just did what he wanted. The block reward was considerably steeper than what everyone was expecting. He also moved forward with 1-minute block times despite everyone's concerns about the increase of orphan blocks. He also didn't address the tail emission concern that should've (in my opinion) been in the code at launch time. Basically, he messed everything up. Then, he disappeared.
After disappearing for a while, thankful_for_today returned to find that the community had taken over the project. Johnny Mnemonic continues:
I, and others, started working on new forks that were closer to what everyone else was hoping for. [...] it was decided that the BitMonero project should just be taken over. There were like 9 or 10 interested parties at the time if my memory is correct. We voted on IRC to drop the "bit" from BitMonero and move forward with the project. Thankful_for_today suddenly resurfaced, and wasn't happy to learn the community had assumed control of the coin. He attempted to maintain his own fork (still calling it "BitMonero") for a while, but that quickly fell into obscurity.
The unfolding of these events show us the roots of Monero. Much like Satoshi Nakamoto, the creators behind CryptoNote/Bytecoin and thankful_for_today remain a mystery^17^, having disappeared without a trace. This enigma only adds to Monero's value.
Since community took over development, believing in the project's potential and its ability to be guided in a better direction, Monero was given one of Bitcoin's most important qualities: a leaderless nature. With no single face or entity directing its path, Monero is safe from potential corruption or harm from a "central authority".
The community continued developing Monero until today. Since then, Monero has undergone a lot of technological improvements, migrations and achievements such as RingCT and RandomX. It also has developed its own Community Crowdfundinc System, conferences such as MoneroKon and Monerotopia are taking place every year, and has a very active community around it.
Monero continues to develop with goals of privacy and security first, ease of use and efficiency second. ^16^
This stands as a testament to the power of a dedicated community operating without a central figure of authority. This decentralized approach aligns with the original ethos of cryptocurrency, making Monero a prime example of community-driven innovation. For this, I thank all the people involved in Monero, that lead it to where it is today.
If you find any information that seems incorrect, unclear or any missing important events, please contact me and I will make the necessary changes.

2025-02-25 03:55:08Here’s a revised timeline of macro-level events from The Mandibles: A Family, 2029–2047 by Lionel Shriver, reimagined in a world where Bitcoin is adopted as a widely accepted form of money, altering the original narrative’s assumptions about currency collapse and economic control. In Shriver’s original story, the failure of Bitcoin is assumed amid the dominance of the bancor and the dollar’s collapse. Here, Bitcoin’s success reshapes the economic and societal trajectory, decentralizing power and challenging state-driven outcomes.
Part One: 2029–2032
-
2029 (Early Year)\ The United States faces economic strain as the dollar weakens against global shifts. However, Bitcoin, having gained traction emerges as a viable alternative. Unlike the original timeline, the bancor—a supranational currency backed by a coalition of nations—struggles to gain footing as Bitcoin’s decentralized adoption grows among individuals and businesses worldwide, undermining both the dollar and the bancor.
-
2029 (Mid-Year: The Great Renunciation)\ Treasury bonds lose value, and the government bans Bitcoin, labeling it a threat to sovereignty (mirroring the original bancor ban). However, a Bitcoin ban proves unenforceable—its decentralized nature thwarts confiscation efforts, unlike gold in the original story. Hyperinflation hits the dollar as the U.S. prints money, but Bitcoin’s fixed supply shields adopters from currency devaluation, creating a dual-economy split: dollar users suffer, while Bitcoin users thrive.
-
2029 (Late Year)\ Dollar-based inflation soars, emptying stores of goods priced in fiat currency. Meanwhile, Bitcoin transactions flourish in underground and online markets, stabilizing trade for those plugged into the bitcoin ecosystem. Traditional supply chains falter, but peer-to-peer Bitcoin networks enable local and international exchange, reducing scarcity for early adopters. The government’s gold confiscation fails to bolster the dollar, as Bitcoin’s rise renders gold less relevant.
-
2030–2031\ Crime spikes in dollar-dependent urban areas, but Bitcoin-friendly regions see less chaos, as digital wallets and smart contracts facilitate secure trade. The U.S. government doubles down on surveillance to crack down on bitcoin use. A cultural divide deepens: centralized authority weakens in Bitcoin-adopting communities, while dollar zones descend into lawlessness.
-
2032\ By this point, Bitcoin is de facto legal tender in parts of the U.S. and globally, especially in tech-savvy or libertarian-leaning regions. The federal government’s grip slips as tax collection in dollars plummets—Bitcoin’s traceability is low, and citizens evade fiat-based levies. Rural and urban Bitcoin hubs emerge, while the dollar economy remains fractured.
Time Jump: 2032–2047
- Over 15 years, Bitcoin solidifies as a global reserve currency, eroding centralized control. The U.S. government adapts, grudgingly integrating bitcoin into policy, though regional autonomy grows as Bitcoin empowers local economies.
Part Two: 2047
-
2047 (Early Year)\ The U.S. is a hybrid state: Bitcoin is legal tender alongside a diminished dollar. Taxes are lower, collected in BTC, reducing federal overreach. Bitcoin’s adoption has decentralized power nationwide. The bancor has faded, unable to compete with Bitcoin’s grassroots momentum.
-
2047 (Mid-Year)\ Travel and trade flow freely in Bitcoin zones, with no restrictive checkpoints. The dollar economy lingers in poorer areas, marked by decay, but Bitcoin’s dominance lifts overall prosperity, as its deflationary nature incentivizes saving and investment over consumption. Global supply chains rebound, powered by bitcoin enabled efficiency.
-
2047 (Late Year)\ The U.S. is a patchwork of semi-autonomous zones, united by Bitcoin’s universal acceptance rather than federal control. Resource scarcity persists due to past disruptions, but economic stability is higher than in Shriver’s original dystopia—Bitcoin’s success prevents the authoritarian slide, fostering a freer, if imperfect, society.
Key Differences
- Currency Dynamics: Bitcoin’s triumph prevents the bancor’s dominance and mitigates hyperinflation’s worst effects, offering a lifeline outside state control.
- Government Power: Centralized authority weakens as Bitcoin evades bans and taxation, shifting power to individuals and communities.
- Societal Outcome: Instead of a surveillance state, 2047 sees a decentralized, bitcoin driven world—less oppressive, though still stratified between Bitcoin haves and have-nots.
This reimagining assumes Bitcoin overcomes Shriver’s implied skepticism to become a robust, adopted currency by 2029, fundamentally altering the novel’s bleak trajectory.

2025-01-19 12:10:10I am so tired of people trying to waste my time with Nostrized imitations of stuff that already exists.
Instagram, but make it Nostr. Twitter, but make it Nostr. GitHub, but make it Nostr. Facebook, but make it Nostr. Wordpress, but make it Nostr. GoodReads, but make it Nostr. TikTok, but make it Nostr.
That stuff already exists, and it wasn't that great the first time around, either. Build something better than that stuff, that can only be brought into existence because of Nostr.
Build something that does something completely and awesomely new. Knock my socks off, bro.
Cuz, ain't nobody got time for that.

Pode demorar um pouco para espalhar os dados, metadados e dados do sistema em todos os dispositivos de armazenamento do RAID se ele contiver muitos dados.
Opções importantes de montagem Btrfs
Nesta seção, vou explicar algumas das importantes opções de montagem do Btrfs. Então vamos começar.
As opções de montagem Btrfs mais importantes são:
**1. acl e noacl
**ACL gerencia permissões de usuários e grupos para os arquivos/diretórios do sistema de arquivos Btrfs.
A opção de montagem acl Btrfs habilita ACL. Para desabilitar a ACL, você pode usar a opção de montagem noacl .
Por padrão, a ACL está habilitada. Portanto, o sistema de arquivos Btrfs usa a opção de montagem acl por padrão.
**2. autodefrag e noautodefrag
**Desfragmentar um sistema de arquivos Btrfs melhorará o desempenho do sistema de arquivos reduzindo a fragmentação de dados.
A opção de montagem autodefrag permite a desfragmentação automática do sistema de arquivos Btrfs.
A opção de montagem noautodefrag desativa a desfragmentação automática do sistema de arquivos Btrfs.
Por padrão, a desfragmentação automática está desabilitada. Portanto, o sistema de arquivos Btrfs usa a opção de montagem noautodefrag por padrão.
**3. compactar e compactar-forçar
**Controla a compactação de dados no nível do sistema de arquivos do sistema de arquivos Btrfs.
A opção compactar compacta apenas os arquivos que valem a pena compactar (se compactar o arquivo economizar espaço em disco).
A opção compress-force compacta todos os arquivos do sistema de arquivos Btrfs, mesmo que a compactação do arquivo aumente seu tamanho.
O sistema de arquivos Btrfs suporta muitos algoritmos de compactação e cada um dos algoritmos de compactação possui diferentes níveis de compactação.
Os algoritmos de compactação suportados pelo Btrfs são: lzo , zlib (nível 1 a 9) e zstd (nível 1 a 15).
Você pode especificar qual algoritmo de compactação usar para o sistema de arquivos Btrfs com uma das seguintes opções de montagem:
- compress=algoritmo:nível
- compress-force=algoritmo:nível
Para obter mais informações, consulte meu artigo Como habilitar a compactação do sistema de arquivos Btrfs .
**4. subvol e subvolid
**Estas opções de montagem são usadas para montar separadamente um subvolume específico de um sistema de arquivos Btrfs.
A opção de montagem subvol é usada para montar o subvolume de um sistema de arquivos Btrfs usando seu caminho relativo.
A opção de montagem subvolid é usada para montar o subvolume de um sistema de arquivos Btrfs usando o ID do subvolume.
Para obter mais informações, consulte meu artigo Como criar e montar subvolumes Btrfs .
**5. dispositivo
A opção de montagem de dispositivo** é usada no sistema de arquivos Btrfs de vários dispositivos ou RAID Btrfs.
Em alguns casos, o sistema operacional pode falhar ao detectar os dispositivos de armazenamento usados em um sistema de arquivos Btrfs de vários dispositivos ou RAID Btrfs. Nesses casos, você pode usar a opção de montagem do dispositivo para especificar os dispositivos que deseja usar para o sistema de arquivos de vários dispositivos Btrfs ou RAID.
Você pode usar a opção de montagem de dispositivo várias vezes para carregar diferentes dispositivos de armazenamento para o sistema de arquivos de vários dispositivos Btrfs ou RAID.
Você pode usar o nome do dispositivo (ou seja, sdb , sdc ) ou UUID , UUID_SUB ou PARTUUID do dispositivo de armazenamento com a opção de montagem do dispositivo para identificar o dispositivo de armazenamento.
Por exemplo,
- dispositivo=/dev/sdb

**6. degraded
A opção de montagem degradada** permite que um RAID Btrfs seja montado com menos dispositivos de armazenamento do que o perfil RAID requer.
Por exemplo, o perfil raid1 requer a presença de 2 dispositivos de armazenamento. Se um dos dispositivos de armazenamento não estiver disponível em qualquer caso, você usa a opção de montagem degradada para montar o RAID mesmo que 1 de 2 dispositivos de armazenamento esteja disponível.
**7. commit
A opção commit** mount é usada para definir o intervalo (em segundos) dentro do qual os dados serão gravados no dispositivo de armazenamento.
O padrão é definido como 30 segundos.
Para definir o intervalo de confirmação para 15 segundos, você pode usar a opção de montagem commit=15 (digamos).
**8. ssd e nossd
A opção de montagem ssd** informa ao sistema de arquivos Btrfs que o sistema de arquivos está usando um dispositivo de armazenamento SSD, e o sistema de arquivos Btrfs faz a otimização SSD necessária.
A opção de montagem nossd desativa a otimização do SSD.
O sistema de arquivos Btrfs detecta automaticamente se um SSD é usado para o sistema de arquivos Btrfs. Se um SSD for usado, a opção de montagem de SSD será habilitada. Caso contrário, a opção de montagem nossd é habilitada.
**9. ssd_spread e nossd_spread
A opção de montagem ssd_spread** tenta alocar grandes blocos contínuos de espaço não utilizado do SSD. Esse recurso melhora o desempenho de SSDs de baixo custo (baratos).
A opção de montagem nossd_spread desativa o recurso ssd_spread .
O sistema de arquivos Btrfs detecta automaticamente se um SSD é usado para o sistema de arquivos Btrfs. Se um SSD for usado, a opção de montagem ssd_spread será habilitada. Caso contrário, a opção de montagem nossd_spread é habilitada.
**10. descarte e nodiscard
Se você estiver usando um SSD que suporte TRIM enfileirado assíncrono (SATA rev3.1), a opção de montagem de descarte** permitirá o descarte de blocos de arquivos liberados. Isso melhorará o desempenho do SSD.
Se o SSD não suportar TRIM enfileirado assíncrono, a opção de montagem de descarte prejudicará o desempenho do SSD. Nesse caso, a opção de montagem nodiscard deve ser usada.
Por padrão, a opção de montagem nodiscard é usada.
**11. norecovery
Se a opção de montagem norecovery** for usada, o sistema de arquivos Btrfs não tentará executar a operação de recuperação de dados no momento da montagem.
**12. usebackuproot e nousebackuproot
Se a opção de montagem usebackuproot for usada, o sistema de arquivos Btrfs tentará recuperar qualquer raiz de árvore ruim/corrompida no momento da montagem. O sistema de arquivos Btrfs pode armazenar várias raízes de árvore no sistema de arquivos. A opção de montagem usebackuproot** procurará uma boa raiz de árvore e usará a primeira boa que encontrar.
A opção de montagem nousebackuproot não verificará ou recuperará raízes de árvore inválidas/corrompidas no momento da montagem. Este é o comportamento padrão do sistema de arquivos Btrfs.
**13. space_cache, space_cache=version, nospace_cache e clear_cache
A opção de montagem space_cache** é usada para controlar o cache de espaço livre. O cache de espaço livre é usado para melhorar o desempenho da leitura do espaço livre do grupo de blocos do sistema de arquivos Btrfs na memória (RAM).
O sistema de arquivos Btrfs suporta 2 versões do cache de espaço livre: v1 (padrão) e v2
O mecanismo de cache de espaço livre v2 melhora o desempenho de sistemas de arquivos grandes (tamanho de vários terabytes).
Você pode usar a opção de montagem space_cache=v1 para definir a v1 do cache de espaço livre e a opção de montagem space_cache=v2 para definir a v2 do cache de espaço livre.
A opção de montagem clear_cache é usada para limpar o cache de espaço livre.
Quando o cache de espaço livre v2 é criado, o cache deve ser limpo para criar um cache de espaço livre v1 .
Portanto, para usar o cache de espaço livre v1 após a criação do cache de espaço livre v2 , as opções de montagem clear_cache e space_cache=v1 devem ser combinadas: clear_cache,space_cache=v1
A opção de montagem nospace_cache é usada para desabilitar o cache de espaço livre.
Para desabilitar o cache de espaço livre após a criação do cache v1 ou v2 , as opções de montagem nospace_cache e clear_cache devem ser combinadas: clear_cache,nosapce_cache
**14. skip_balance
Por padrão, a operação de balanceamento interrompida/pausada de um sistema de arquivos Btrfs de vários dispositivos ou RAID Btrfs será retomada automaticamente assim que o sistema de arquivos Btrfs for montado. Para desabilitar a retomada automática da operação de equilíbrio interrompido/pausado em um sistema de arquivos Btrfs de vários dispositivos ou RAID Btrfs, você pode usar a opção de montagem skip_balance .**
**15. datacow e nodatacow
A opção datacow** mount habilita o recurso Copy-on-Write (CoW) do sistema de arquivos Btrfs. É o comportamento padrão.
Se você deseja desabilitar o recurso Copy-on-Write (CoW) do sistema de arquivos Btrfs para os arquivos recém-criados, monte o sistema de arquivos Btrfs com a opção de montagem nodatacow .
**16. datasum e nodatasum
A opção datasum** mount habilita a soma de verificação de dados para arquivos recém-criados do sistema de arquivos Btrfs. Este é o comportamento padrão.
Se você não quiser que o sistema de arquivos Btrfs faça a soma de verificação dos dados dos arquivos recém-criados, monte o sistema de arquivos Btrfs com a opção de montagem nodatasum .
Perfis Btrfs
Um perfil Btrfs é usado para informar ao sistema de arquivos Btrfs quantas cópias dos dados/metadados devem ser mantidas e quais níveis de RAID devem ser usados para os dados/metadados. O sistema de arquivos Btrfs contém muitos perfis. Entendê-los o ajudará a configurar um RAID Btrfs da maneira que você deseja.
Os perfis Btrfs disponíveis são os seguintes:
single : Se o perfil único for usado para os dados/metadados, apenas uma cópia dos dados/metadados será armazenada no sistema de arquivos, mesmo se você adicionar vários dispositivos de armazenamento ao sistema de arquivos. Assim, 100% do espaço em disco de cada um dos dispositivos de armazenamento adicionados ao sistema de arquivos pode ser utilizado.
dup : Se o perfil dup for usado para os dados/metadados, cada um dos dispositivos de armazenamento adicionados ao sistema de arquivos manterá duas cópias dos dados/metadados. Assim, 50% do espaço em disco de cada um dos dispositivos de armazenamento adicionados ao sistema de arquivos pode ser utilizado.
raid0 : No perfil raid0 , os dados/metadados serão divididos igualmente em todos os dispositivos de armazenamento adicionados ao sistema de arquivos. Nesta configuração, não haverá dados/metadados redundantes (duplicados). Assim, 100% do espaço em disco de cada um dos dispositivos de armazenamento adicionados ao sistema de arquivos pode ser usado. Se, em qualquer caso, um dos dispositivos de armazenamento falhar, todo o sistema de arquivos será corrompido. Você precisará de pelo menos dois dispositivos de armazenamento para configurar o sistema de arquivos Btrfs no perfil raid0 .
raid1 : No perfil raid1 , duas cópias dos dados/metadados serão armazenadas nos dispositivos de armazenamento adicionados ao sistema de arquivos. Nesta configuração, a matriz RAID pode sobreviver a uma falha de unidade. Mas você pode usar apenas 50% do espaço total em disco. Você precisará de pelo menos dois dispositivos de armazenamento para configurar o sistema de arquivos Btrfs no perfil raid1 .
raid1c3 : No perfil raid1c3 , três cópias dos dados/metadados serão armazenadas nos dispositivos de armazenamento adicionados ao sistema de arquivos. Nesta configuração, a matriz RAID pode sobreviver a duas falhas de unidade, mas você pode usar apenas 33% do espaço total em disco. Você precisará de pelo menos três dispositivos de armazenamento para configurar o sistema de arquivos Btrfs no perfil raid1c3 .
raid1c4 : No perfil raid1c4 , quatro cópias dos dados/metadados serão armazenadas nos dispositivos de armazenamento adicionados ao sistema de arquivos. Nesta configuração, a matriz RAID pode sobreviver a três falhas de unidade, mas você pode usar apenas 25% do espaço total em disco. Você precisará de pelo menos quatro dispositivos de armazenamento para configurar o sistema de arquivos Btrfs no perfil raid1c4 .
raid10 : No perfil raid10 , duas cópias dos dados/metadados serão armazenadas nos dispositivos de armazenamento adicionados ao sistema de arquivos, como no perfil raid1 . Além disso, os dados/metadados serão divididos entre os dispositivos de armazenamento, como no perfil raid0 .
O perfil raid10 é um híbrido dos perfis raid1 e raid0 . Alguns dos dispositivos de armazenamento formam arrays raid1 e alguns desses arrays raid1 são usados para formar um array raid0 . Em uma configuração raid10 , o sistema de arquivos pode sobreviver a uma única falha de unidade em cada uma das matrizes raid1 .
Você pode usar 50% do espaço total em disco na configuração raid10 . Você precisará de pelo menos quatro dispositivos de armazenamento para configurar o sistema de arquivos Btrfs no perfil raid10 .
raid5 : No perfil raid5 , uma cópia dos dados/metadados será dividida entre os dispositivos de armazenamento. Uma única paridade será calculada e distribuída entre os dispositivos de armazenamento do array RAID.
Em uma configuração raid5 , o sistema de arquivos pode sobreviver a uma única falha de unidade. Se uma unidade falhar, você pode adicionar uma nova unidade ao sistema de arquivos e os dados perdidos serão calculados a partir da paridade distribuída das unidades em execução.
Você pode usar 1 00x(N-1)/N % do total de espaços em disco na configuração raid5 . Aqui, N é o número de dispositivos de armazenamento adicionados ao sistema de arquivos. Você precisará de pelo menos três dispositivos de armazenamento para configurar o sistema de arquivos Btrfs no perfil raid5 .
raid6 : No perfil raid6 , uma cópia dos dados/metadados será dividida entre os dispositivos de armazenamento. Duas paridades serão calculadas e distribuídas entre os dispositivos de armazenamento do array RAID.
Em uma configuração raid6 , o sistema de arquivos pode sobreviver a duas falhas de unidade ao mesmo tempo. Se uma unidade falhar, você poderá adicionar uma nova unidade ao sistema de arquivos e os dados perdidos serão calculados a partir das duas paridades distribuídas das unidades em execução.
Você pode usar 100x(N-2)/N % do espaço total em disco na configuração raid6 . Aqui, N é o número de dispositivos de armazenamento adicionados ao sistema de arquivos. Você precisará de pelo menos quatro dispositivos de armazenamento para configurar o sistema de arquivos Btrfs no perfil raid6 .

2025-05-27 09:21:45I've been thinking about how to improve my seed backup in a cheap and cool way, mostly for fun. Until now, I had the seed written on a piece of paper in a desk drawer, and I wanted something more durable and fire-proof.
After searching online, I found two options I liked the most: the Cryptosteel Capsule and the Trezor Keep. These products are nice but quite expensive, and I didn't want to spend that much on my seed backup. Privacy is also important, and sharing details like a shipping address makes me uncomfortable. This concern has grown since the Ledger incident^1. A $5 wrench attack^2 seems too cheap, even if you only hold a few sats.
Upon seeing the design of Cryptosteel, I considered creating something similar at home. Although it may not be as cool as their device, it could offer almost the same in terms of robustness and durability.
Step 1: Get the materials and tools
When choosing the materials, you will want to go with stainless steel. It is durable, resistant to fire, water, and corrosion, very robust, and does not rust. Also, its price point is just right; it's not the cheapest, but it's cheap for the value you get.
I went to a material store and bought:
- Two bolts
- Two hex nuts and head nuts for the bolts
- A bag of 30 washers
All items were made of stainless steel. The total price was around €6. This is enough for making two seed backups.
You will also need:
- A set of metal letter stamps (I bought a 2mm-size letter kit since my washers were small, 6mm in diameter)
- You can find these in local stores or online marketplaces. The set I bought cost me €13.
- A good hammer
- A solid surface to stamp on
Total spent: 19€ for two backups
Step 2: Stamp and store
Once you have all the materials, you can start stamping your words. There are many videos on the internet that use fancy 3D-printed tools to get the letters nicely aligned, but I went with the free-hand option. The results were pretty decent.
I only stamped the first 4 letters for each word since the BIP-39 wordlist allows for this. Because my stamping kit did not include numbers, I used alphabet letters to define the order. This way, if all the washers were to fall off, I could still reassemble the seed correctly.
The final result
So this is the final result. I added two smaller washers as protection and also put the top washer reversed so the letters are not visible:
Compared to the Cryptosteel or the Trezor Keep, its size is much more compact. This makes for an easier-to-hide backup, in case you ever need to hide it inside your human body.
Some ideas
Tamper-evident seal
To enhance the security this backup, you can consider using a tamper-evident seal. This can be easily achieved by printing a unique image or using a specific day's newspaper page (just note somewhere what day it was).
Apply a thin layer of glue to the washer's surface and place the seal over it. If someone attempts to access the seed, they will be forced to destroy the seal, which will serve as an evident sign of tampering.
This simple measure will provide an additional layer of protection and allow you to quickly identify any unauthorized access attempts.
Note that this method is not resistant to outright theft. The tamper-evident seal won't stop a determined thief but it will prevent them from accessing your seed without leaving any trace.
Redundancy
Make sure to add redundancy. Make several copies of this cheap backup, and store them in separate locations.
Unique wordset
Another layer of security could be to implement your own custom mnemonic dictionary. However, this approach has the risk of permanently losing access to your funds if not implemented correctly.
If done properly, you could potentially end up with a highly secure backup, as no one else would be able to derive the seed phrase from it. To create your custom dictionary, assign a unique number from 1 to 2048 to a word of your choice. Maybe you could use a book, and index the first 2048 unique words that appear. Make sure to store this book and even get a couple copies of it (digitally and phisically).
This self-curated set of words will serve as your personal BIP-39 dictionary. When you need to translate between your custom dictionary and the official BIP-39 wordlist, simply use the index number to find the corresponding word in either list.

2025-02-13 06:16:49My favorite line in any Marvel movie ever is in “Captain America.” After Captain America launches seemingly a hopeless assault on Red Skull’s base and is captured, we get this line:
“Arrogance may not be a uniquely American trait, but I must say, you do it better than anyone.”
Yesterday, I came across a comment on the song Devil Went Down to Georgia that had a very similar feel to it:
America has seemingly always been arrogant, in a uniquely American way. Manifest Destiny, for instance. The rest of the world is aware of this arrogance, and mocks Americans for it. A central point in modern US politics is the deriding of racist, nationalist, supremacist Americans.
That’s not what I see. I see American Arrogance as not only a beautiful statement about what it means to be American. I see it as an ode to the greatness of humanity in its purest form.
For most countries, saying “our nation is the greatest” is, in fact, twinged with some level of racism. I still don’t have a problem with it. Every group of people should be allowed to feel pride in their accomplishments. The destruction of the human spirit since the end of World War 2, where greatness has become a sin and weakness a virtue, has crushed the ability of people worldwide to strive for excellence.
But I digress. The fears of racism and nationalism at least have a grain of truth when applied to other nations on the planet. But not to America.
That’s because the definition of America, and the prototype of an American, has nothing to do with race. The definition of Americanism is freedom. The founding of America is based purely on liberty. On the God-given rights of every person to live life the way they see fit.
American Arrogance is not a statement of racial superiority. It’s barely a statement of national superiority (though it absolutely is). To me, when an American comments on the greatness of America, it’s a statement about freedom. Freedom will always unlock the greatness inherent in any group of people. Americans are definitionally better than everyone else, because Americans are freer than everyone else. (Or, at least, that’s how it should be.)
In Devil Went Down to Georgia, Johnny is approached by the devil himself. He is challenged to a ridiculously lopsided bet: a golden fiddle versus his immortal soul. He acknowledges the sin in accepting such a proposal. And yet he says, “God, I know you told me not to do this. But I can’t stand the affront to my honor. I am the greatest. The devil has nothing on me. So God, I’m gonna sin, but I’m also gonna win.”

A once-functional object, now eroded by time and human intervention, stripped of its original purpose. Layers of presence accumulate—marks, alterations, traces of intent—until the very essence is obscured. Restoration is paradoxical: to reclaim, one must erase. Yet erasure is an impossibility, for to remove these imprints is to deny the existence of those who shaped them.
The work stands as a meditation on entropy, memory, and the irreversible dialogue between creation and decay.

2025-05-27 09:21:43kycnot.me features a somewhat hidden tool that some users may not be aware of. Every month, an automated job crawls every listed service's Terms of Service (ToS) and FAQ pages and conducts an AI-driven analysis, generating a comprehensive overview that highlights key points related to KYC and user privacy.
Here's an example: Changenow's Tos Review
Why?
ToS pages typically contain a lot of complicated text. Since the first versions of kycnot.me, I have tried to provide users a comprehensive overview of what can be found in such documents. This automated method keeps the information up-to-date every month, which was one of the main challenges with manual updates.
A significant part of the time I invest in investigating a service for kycnot.me involves reading the ToS and looking for any clauses that might indicate aggressive KYC practices or privacy concerns. For the past four years, I performed this task manually. However, with advancements in language models, this process can now be somewhat automated. I still manually review the ToS for a quick check and regularly verify the AI’s findings. However, over the past three months, this automated method has proven to be quite reliable.
Having a quick ToS overview section allows users to avoid reading the entire ToS page. Instead, you can quickly read the important points that are grouped, summarized, and referenced, making it easier and faster to understand the key information.
Limitations
This method has a key limitation: JS-generated pages. For this reason, I was using Playwright in my crawler implementation. I plan to make a release addressing this issue in the future. There are also sites that don't have ToS/FAQ pages, but these sites already include a warning in that section.
Another issue is false positives. Although not very common, sometimes the AI might incorrectly interpret something harmless as harmful. Such errors become apparent upon reading; it's clear when something marked as bad should not be categorized as such. I manually review these cases regularly, checking for anything that seems off and then removing any inaccuracies.
Overall, the automation provides great results.
How?
There have been several iterations of this tool. Initially, I started with GPT-3.5, but the results were not good in any way. It made up many things, and important thigs were lost on large ToS pages. I then switched to GPT-4 Turbo, but it was expensive. Eventually, I settled on Claude 3 Sonnet, which provides a quality compromise between GPT-3.5 and GPT-4 Turbo at a more reasonable price, while allowing a generous 200K token context window.
I designed a prompt, which is open source^1, that has been tweaked many times and will surely be adjusted further in the future.
For the ToS scraping part, I initially wrote a scraper API using Playwright^2, but I replaced it with Jina AI Reader^3, which works quite well and is designed for this task.
Non-conflictive ToS
All services have a dropdown in the ToS section called "Non-conflictive ToS Reviews." These are the reviews that the AI flagged as not needing a user warning. I still provide these because I think they may be interesting to read.
Feedback and contributing
You can give me feedback on this tool, or share any inaccuraties by either opening an issue on Codeberg^4 or by contacting me ^5.
You can contribute with pull requests, which are always welcome, or you can support this project with any of the listed ways.

The Bitcoin Mempool: Relay Network DynamicsIn the last Mempool article, I went over the different kinds of relay policy filters, why they exist, and the incentives that ultimately decide how effective each class of filter is at preventing the confirmation of different classes of transactions. In this piece I’ll be looking at the dynamics of the relay network when some nodes on the network are running different relay policies compared to other nodes.
All else being equal, when nodes on the network are running homogenous relay policies in their mempools, all transactions should propagate across the entire network given that they pay the minimum feerate necessary not to be evicted from a node’s mempool during times of large transaction backlogs. This changes when different nodes on the network are running heterogenous policies.
The Bitcoin relay network operates on a best effort basis, using what is called a flood-fill architecture. This means that when a transaction is received by one node, it is forwarded to every other node it is connected to except the one that it received the transaction from. This is a highly inefficient network architecture, but in the context of a decentralized system it provides a high degree of guarantee that the transaction will eventually reach its intended destination, the miners.
Introducing filters in a node’s relay policy to restrict the relaying of otherwise valid transactions in theory introduces friction to the propagation of that transaction, and degrades the reliability of the network’s ability to perform this function. In practice, things aren’t that simple.
How Much Friction Prevents Propagation
Let’s look at a simplified example of different network node compositions. In the following graphics blue nodes represent ones that will propagate some arbitrary class of consensus valid transactions, and red nodes represent ones that will not propagate those transactions. The collective set of miners is denoted in the center as a simple representation of where transacting users ultimately want their transactions to wind up so as to eventually be confirmed in the blockchain.
This is a model of the network in which the nodes refusing to propagate these transactions are a clear minority. As you can clearly see, any node on the network that accepts them has a clear path to relay them to the miners. The two nodes attempting to restrict the transactions propagation across the network have no effect on their eventual receipt by miners’ nodes.
In this diagram, you can see that almost half of the example network is instituting filtering policies for this class of transactions. Despite this, only part of the network that propagates these transactions is cut off from a path to miners. The rest of the nodes not filtering still have a clear path to miners. This has introduced some degree of friction for a subset of users, but the others can still freely engage in propagating these transactions.
Even for the users that are affected by filtering nodes, only a single connection to the rest of the network nodes that are not cut off from miners (or a direct connection to a miner) is necessary in order for that friction to be removed. If the real relay network were to have a similar composition to this example, all it would take is a single new connection to alleviate the problem.
In this scenario, only a tiny minority of the network is actually propagating these transactions. The rest of the network is engaging in filtering policies to prevent their propagation. Even in this case however, those nodes that are not filtering still have a clear path to propagate them to miners.
Only this tiny minority of non-filtering nodes is necessary in order to ensure their eventual propagation to miners. Preferential peering logic, i.e. functionality to ensure that your node prefers peers who implement the same software version or relay policies. These types of solutions can guarantee that peers who will propagate something to others won’t find each other and maintain connections amongst themselves across the network.
The Tolerant Minority
As you can see looking at these different examples, even in the face of an overwhelming majority of the public network engaging in filtering of a specific class of transactions, all that is necessary for them to successfully propagate across the network to miners is a small minority of the network to propagate and relay them.
These nodes will essentially, through whatever technical mechanism, create a “sub-network” within the larger public relay network in order to guarantee that there are viable paths from users engaging in these types of transactions to the miners willing to include them in their blocks.
There is essentially nothing that can be done to counter this dynamic except to engage in a sybil attack against all of these nodes, and sybil attacks only need a single honest connection in order to be completely defeated. As well, an honest node creating a very large number of connections with other nodes on the network can raise the cost of such a sybil attack exorbitantly. The more connections it creates, the more sybil nodes must be spun up in order to consume all of its connection slots.
What If There Is No Minority?
So what if there is no Tolerant Minority? What will happen to this class of transactions in that case?
If users still want to make them and pay fees to miners for them, they will be confirmed. Miners will simply set up an API. The role of miners is to confirm transactions, and the reason they do so is to maximize profit. Miners are not selfless entities, or morally or ideologically motivated, they are a business. They exist to make money.
If users exist that are willing to pay them money for a certain type of transaction, and the entirety of the public relay network is refusing to propagate those transactions to miners in order to include them in blocks, miners will create another way for users to submit those transactions to them.
It is simply the rational move to make as a profit motivated actor when customers exist that wish to pay you money.
Relay Policy Is Not A Replacement For Consensus
At the end of the day, relay policy cannot successfully censor transactions if they are consensus valid, users are willing to pay for them, and miners do not have some extenuating circumstances to turn down the fees users are willing to pay (such as causing material damage or harm to nodes on the network, i.e. crashing nodes, propagating blocks that take hours to verify on a consumer PC, etc.).
If some class of transactions is truly seen as undesirable by Bitcoin users and node operators, there is no solution to stopping them from being confirmed in the blockchain short of enacting a consensus change to make them invalid.
If it were possible to simply prevent transactions from being confirmed by filtering policies implemented on the relay network, then Bitcoin would not be censorship resistant.

2025-02-25 15:20:39If you don't know where your posts are, you might as well just stay in the centralized Twitter. You either take control of your relay lists, or they will control you. Amethyst offers several lists of relays for our users. We are going to go one by one to help clarify what they are and which options are best for each one.
Public Home/Outbox Relays
Home relays store all YOUR content: all your posts, likes, replies, lists, etc. It's your home. Amethyst will send your posts here first. Your followers will use these relays to get new posts from you. So, if you don't have anything there, they will not receive your updates.
Home relays must allow queries from anyone, ideally without the need to authenticate. They can limit writes to paid users without affecting anyone's experience.
This list should have a maximum of 3 relays. More than that will only make your followers waste their mobile data getting your posts. Keep it simple. Out of the 3 relays, I recommend: - 1 large public, international relay: nos.lol, nostr.mom, relay.damus.io, etc. - 1 personal relay to store a copy of all your content in a place no one can delete. Go to relay.tools and never be censored again. - 1 really fast relay located in your country: paid options like http://nostr.wine are great
Do not include relays that block users from seeing posts in this list. If you do, no one will see your posts.
Public Inbox Relays
This relay type receives all replies, comments, likes, and zaps to your posts. If you are not getting notifications or you don't see replies from your friends, it is likely because you don't have the right setup here. If you are getting too much spam in your replies, it's probably because your inbox relays are not protecting you enough. Paid relays can filter inbox spam out.
Inbox relays must allow anyone to write into them. It's the opposite of the outbox relay. They can limit who can download the posts to their paid subscribers without affecting anyone's experience.
This list should have a maximum of 3 relays as well. Again, keep it small. More than that will just make you spend more of your data plan downloading the same notifications from all these different servers. Out of the 3 relays, I recommend: - 1 large public, international relay: nos.lol, nostr.mom, relay.damus.io, etc. - 1 personal relay to store a copy of your notifications, invites, cashu tokens and zaps. - 1 really fast relay located in your country: go to nostr.watch and find relays in your country
Terrible options include: - nostr.wine should not be here. - filter.nostr.wine should not be here. - inbox.nostr.wine should not be here.
DM Inbox Relays
These are the relays used to receive DMs and private content. Others will use these relays to send DMs to you. If you don't have it setup, you will miss DMs. DM Inbox relays should accept any message from anyone, but only allow you to download them.
Generally speaking, you only need 3 for reliability. One of them should be a personal relay to make sure you have a copy of all your messages. The others can be open if you want push notifications or closed if you want full privacy.
Good options are: - inbox.nostr.wine and auth.nostr1.com: anyone can send messages and only you can download. Not even our push notification server has access to them to notify you. - a personal relay to make sure no one can censor you. Advanced settings on personal relays can also store your DMs privately. Talk to your relay operator for more details. - a public relay if you want DM notifications from our servers.
Make sure to add at least one public relay if you want to see DM notifications.
Private Home Relays
Private Relays are for things no one should see, like your drafts, lists, app settings, bookmarks etc. Ideally, these relays are either local or require authentication before posting AND downloading each user\'s content. There are no dedicated relays for this category yet, so I would use a local relay like Citrine on Android and a personal relay on relay.tools.
Keep in mind that if you choose a local relay only, a client on the desktop might not be able to see the drafts from clients on mobile and vice versa.
Search relays:
This is the list of relays to use on Amethyst's search and user tagging with @. Tagging and searching will not work if there is nothing here.. This option requires NIP-50 compliance from each relay. Hit the Default button to use all available options on existence today: - nostr.wine - relay.nostr.band - relay.noswhere.com
Local Relays:
This is your local storage. Everything will load faster if it comes from this relay. You should install Citrine on Android and write ws://localhost:4869 in this option.
General Relays:
This section contains the default relays used to download content from your follows. Notice how you can activate and deactivate the Home, Messages (old-style DMs), Chat (public chats), and Global options in each.
Keep 5-6 large relays on this list and activate them for as many categories (Home, Messages (old-style DMs), Chat, and Global) as possible.
Amethyst will provide additional recommendations to this list from your follows with information on which of your follows might need the additional relay in your list. Add them if you feel like you are missing their posts or if it is just taking too long to load them.
My setup
Here's what I use: 1. Go to relay.tools and create a relay for yourself. 2. Go to nostr.wine and pay for their subscription. 3. Go to inbox.nostr.wine and pay for their subscription. 4. Go to nostr.watch and find a good relay in your country. 5. Download Citrine to your phone.
Then, on your relay lists, put:
Public Home/Outbox Relays: - nostr.wine - nos.lol or an in-country relay. -
.nostr1.com Public Inbox Relays - nos.lol or an in-country relay -
.nostr1.com DM Inbox Relays - inbox.nostr.wine -
.nostr1.com Private Home Relays - ws://localhost:4869 (Citrine) -
.nostr1.com (if you want) Search Relays - nostr.wine - relay.nostr.band - relay.noswhere.com
Local Relays - ws://localhost:4869 (Citrine)
General Relays - nos.lol - relay.damus.io - relay.primal.net - nostr.mom
And a few of the recommended relays from Amethyst.
Final Considerations
Remember, relays can see what your Nostr client is requesting and downloading at all times. They can track what you see and see what you like. They can sell that information to the highest bidder, they can delete your content or content that a sponsor asked them to delete (like a negative review for instance) and they can censor you in any way they see fit. Before using any random free relay out there, make sure you trust its operator and you know its terms of service and privacy policies.

Sponsored reviews are independent from the kycnot.me list, being only part of the blog. The reviews have no impact on the scores of the listings or their continued presence on the list. Should any issues arise, I will not hesitate to remove any listing. Reviews are in collaboration with Orangefren.
The review
Swapter.io is an all-purpose instant exchange. They entered the scene in the depths of the bear market about 2 years ago in June of 2022.
| Pros | Cons | | --------------- | ---------------------------------- | | Low fees | Shotgun KYC with opaque triggers | | Large liquidity | Relies on 3rd party liquidity | | Works over Tor | Front-end not synced with back-end | | Pretty UI | |
Rating: ★★★☆☆ Service Website: swapter.io
⚠️ There is an ongoing issue with this service: read more on Reddit.
Test Trades
During our testing we performed a trade from XMR to LTC, and then back to XMR.
Our first trade had the ID of:
mpUitpGemhN8jjNAjQuo6EvQ
. We were promised 0.8 LTC for sending 0.5 XMR, before we sent the Monero. When the Monero arrived we were sent 0.799 LTC.On the return journey we performed trade with ID:
yaCRb5pYcRKAZcBqg0AzEGYg
. This time we were promised 0.4815 XMR for sending 0.799 LTC. After Litecoin arrived we were sent 0.4765 XMR.As such we saw a discrepancy of
~0.1%
in the first trade and~1%
in the second trade. Considering those trades were floating we determine the estimates presented in the UI to be highly accurate and honest.Of course Swapter could've been imposing a large fee on their estimates, but we checked their estimates against CoinGecko and found the difference to be equivalent to a fee of just over
0.5%
. Perfectly in line with other swapping services.Trading
Swapter supports BTC, LTC, XMR and well over a thousand other coins. Sadly they don't support the Lightning Network. For the myriad of currencies they deal with they provide massive upper limits. You could exchange tens, or even hundreds, of thousands of dollars worth of cryptocurrency in a single trade (although we wouldn't recommend it).
The flip side to this is that Swapter relies on 3rd party liquidity. Aside from the large liqudity this also benefits the user insofar as it allows for very low fees. However, it also comes with a negative - the 3rd party gets to see all your trades. Unfortunately Swapter opted not to share where they source their liquidity in their Privacy Policy or Terms of Service.
KYC & AML policies
Swapter reserves the right to require its users to provide their full name, their date of birth, their address and government-issued ID. A practice known as "shotgun KYC". This should not happen often - in our testing it never did - however it's not clear when exactly it could happen. The AML & KYC policy provided on Swapter's website simply states they will put your trade on hold if their "risk scoring system [deems it] as suspicious".
Worse yet, if they determine that "any of the information [the] customer provided is incorrect, false, outdated, or incomplete" then Swapter may decide to terminate all of the services they provide to the user. What exactly would happen to their funds in such a case remains unclear.
The only clarity we get is that the Swapter policy outlines a designated 3rd party that will verify the information provided by the user. The third party's name is Sum & Substance Ltd, also simply known as samsub and available at sumsub.com
It's understandable that some exchanges will decide on a policy of this sort, especially when they rely on external liquidity, but we would prefer more clarity be given. When exactly is a trade suspicious?
Tor
We were pleased to discover Swapter works over Tor. However, they do not provide a Tor mirror, nor do they work without JavaScript. Additionally, we found that some small features, such as the live chat, did not work over Tor. Fortunately, other means of contacting their support are still available.
UI
We have found the Swapter UI to be very modern, straightforward and simple to use. It's available in 4 languages (English, French, Dutch and Russian), although we're unable to vouch for the quality of some of those, the ones that we used seemed perfectly serviceable.
Our only issue with the UI was that it claims the funds have been sent following the trade, when in reality it seems to take the backend a minute or so to actually broadcast the transaction.
Getting in touch
Swapter's team has a chat on their website, a support email address and a support Telegram. Their social media presence in most active on Telegram and X (formerly Twitter).

@ b8851a06:9b120ba1
2025-01-14 15:28:32It Begins with a Click
It starts with a click: “Do you agree to our terms and conditions?”\ You scroll, you click, you comply. A harmless act, right? But what if every click was a surrender? What if every "yes" was another link in the chain binding you to a life where freedom requires approval?
This is the age of permission. Every aspect of your life is mediated by gatekeepers. Governments demand forms, corporations demand clicks, and algorithms demand obedience. You’re free, of course, as long as you play by the rules. But who writes the rules? Who decides what’s allowed? Who owns your life?
Welcome to Digital Serfdom
We once imagined the internet as a digital frontier—a vast, open space where ideas could flow freely and innovation would know no bounds. But instead of creating a decentralized utopia, we built a new feudal system.
- Your data? Owned by the lords of Big Tech.
- Your money? Controlled by banks and bureaucrats who can freeze it on a whim.
- Your thoughts? Filtered by algorithms that reward conformity and punish dissent.
The modern internet is a land of serfs and lords, and guess who’s doing the farming? You. Every time you agree to the terms, accept the permissions, or let an algorithm decide for you, you till the fields of a system designed to control, not liberate.
They don’t call it control, of course. They call it “protection.” They say, “We’re keeping you safe,” as they build a cage so big you can’t see the bars.
Freedom in Chains
But let’s be honest: we’re not just victims of this system—we’re participants. We’ve traded freedom for convenience, sovereignty for security. It’s easier to click “I Agree” than to read the fine print. It’s easier to let someone else hold your money than to take responsibility for it yourself. It’s easier to live a life of quiet compliance than to risk the chaos of true independence.
We tell ourselves it’s no big deal. What’s one click? What’s one form? But the permissions pile up. The chains grow heavier. And one day, you wake up and realize you’re free to do exactly what the system allows—and nothing more.
The Great Unpermissioning
It doesn’t have to be this way. You don’t need their approval. You don’t need their systems. You don’t need their permission.
The Great Unpermissioning is not a movement—it’s a mindset. It’s the refusal to accept a life mediated by gatekeepers. It’s the quiet rebellion of saying, “No.” It’s the realization that the freedom you seek won’t be granted—it must be reclaimed.
- Stop asking. Permission is their tool. Refusal is your weapon.
- Start building. Embrace tools that decentralize power: Bitcoin, encryption, open-source software, decentralized communication. Build systems they can’t control.
- Stand firm. They’ll tell you it’s dangerous. They’ll call you a radical. But remember: the most dangerous thing you can do is comply.
The path won’t be easy. Freedom never is. But it will be worth it.
The New Frontier
The age of permission has turned us into digital serfs, but there’s a new frontier on the horizon. It’s a world where you control your money, your data, your decisions. It’s a world of encryption, anonymity, and sovereignty. It’s a world built not on permission but on principles.
This world won’t be given to you. You have to build it. You have to fight for it. And it starts with one simple act: refusing to comply.
A Final Word
They promised us safety, but what they delivered was submission. The age of permission has enslaved us to the mundane, the monitored, and the mediocre. The Great Unpermissioning isn’t about tearing down the old world—it’s about walking away from it.
You don’t need to wait for their approval. You don’t need to ask for their permission. The freedom you’re looking for is already yours. Permission is their power—refusal is yours.

2024-12-16 16:38:53Brett Scott’s recent metaphor of Bitcoin as a wrestling gimmick, reliant on hype and dollar-dependence, reduces a groundbreaking monetary innovation to shallow theatrics. Let’s address his key missteps with hard facts.
1. Bitcoin Isn’t an Asset in the System—It’s the System
Scott claims Bitcoin competes with stocks, bonds, and gold in a financial "wrestling ring." This misrepresents Bitcoin’s purpose: it’s not an investment vehicle but a decentralized monetary network. Unlike assets, Bitcoin enables permissionless global value transfer, censorship resistance, and self-sovereign wealth storage—capabilities fiat currencies cannot match.
Fact: Bitcoin processes over $8 billion in daily transactions, settling more value annually than PayPal and Venmo combined. It isn’t competing with assets but offering an alternative to the monetary system itself.
2. Volatility Is Growth, Not Failure
Scott critiques Bitcoin’s price volatility as evidence of its unsuitability as "money." However, volatility is a natural stage in the adoption of transformative technology. Bitcoin is scaling from niche use to global recognition. Its growing liquidity and adoption already make it more stable than fiat in inflationary economies.
Fact: Bitcoin’s annualized volatility has decreased by 53% since 2013 and continues to stabilize as adoption rises. It’s the best-performing asset of the last decade, with an average annual ROI of 147%—far outpacing stocks, gold, and real estate. As of February 2024, Bitcoin's volatility was lower than roughly 900 stocks in the S and P 1500 and 190 stocks in the S and P 500. It continues to stabilize as adoption rises, making it an increasingly attractive store of value.
3. Bitcoin’s Utility Extends Beyond Countertrade
Scott diminishes Bitcoin to a "countertrade token," reliant on its dollar price. This ignores Bitcoin’s primary functions:
- Medium of exchange: Used in remittances, cross-border payments, and for the unbanked in Africa today (e.g., Ghana, Nigeria, Kenya).
- Store of value: A hedge against inflation and failing fiat systems (e.g., Argentina, Lebanon, Turkey).
- Decentralized reserve asset: Held by over 1,500 public and private institutions, including Tesla, MicroStrategy, and nations like El Salvador.
Fact: Lightning Network adoption has grown 1,500% in capacity since 2021, enabling microtransactions and reducing fees—making Bitcoin increasingly viable for everyday use. As of December 2024, Sub-Saharan Africa accounts for 2.7% of global cryptocurrency transaction volume, with Nigeria ranking second worldwide in crypto adoption. This demonstrates Bitcoin's real-world utility beyond mere speculation.
4. Bitcoin Isn’t Controlled by the Dollar
Scott suggests Bitcoin strengthens the dollar system rather than challenging it. In truth, Bitcoin exists outside the control of any nation-state. It offers people in authoritarian regimes and hyperinflationary economies a lifeline when their local currencies fail.
Fact: Over 70% of Bitcoin transactions occur outside the U.S., with adoption highest in countries like Nigeria, India, Venezuela, China, the USA and Ukraine—where the dollar isn’t dominant but government overreach and fiat collapse are. This global distribution shows Bitcoin's independence from dollar dominance.
5. Hype vs. Adoption
Scott mocks Bitcoin’s evangelists but fails to acknowledge its real-world traction. Bitcoin adoption isn’t driven by hype but by trustless, verifiable technology solving real-world problems. People don’t buy Bitcoin for "kayfabe"; they buy it for what it does.
Fact: Bitcoin wallets reached 500 million globally in 2023. El Salvador’s Chivo wallet onboarded 4 million users (60% of the population) within a year—far from a gimmick in action. As of December 2024, El Salvador's Bitcoin portfolio has crossed $632 million in value, with an unrealized profit of $362 million, demonstrating tangible benefits beyond hype.
6. The Dollar’s Coercive Monopoly vs. Bitcoin’s Freedom
Scott defends fiat money as more than "just numbers," backed by state power. He’s correct: fiat relies on coercion, legal mandates, and inflationary extraction. Bitcoin, by contrast, derives value from transparent scarcity (capped at 21 million coins) and decentralized consensus, not military enforcement or political whims.
Fact: Bitcoin’s inflation rate is just 1.8%—lower than gold or the U.S. dollar—and will approach 0% by 2140. No fiat currency can match this predictability. As of December 2024, Bitcoin processes an average of 441,944 transactions per day, showcasing its growing role as a global, permissionless monetary system free from centralized control.
Conclusion: The Revolution Is Real
Scott’s "wrestling gimmick" analogy trivializes Bitcoin’s purpose and progress. Bitcoin isn’t just a speculative asset—it’s the first truly decentralized, apolitical form of money. Whether as a hedge against inflation, a tool for financial inclusion, or a global settlement network, Bitcoin is transforming how we think about money.
Dismiss it as a gimmick at your peril. The world doesn’t need another asset—it needs Bitcoin.
"If you don't believe me or don't get it, I don't have time to try to convince you, sorry." Once Satoshi said.
There is no second best.

Something is Brewing in Ireland: A Sound Punt Is Released, As Bitcoin Enters The National ConversationFor years, Bitcoin in Ireland has quietly simmered at the grassroots level—discussed in pubs and meetups, debated in Telegram groups, and occasionally splashed across headlines with predictable suspicion. But recently, the temperature is beginning to rise. With the release of “A Sound Punt: The Case for Ireland’s Interest in Bitcoin” by Bitcoin Network Ireland (BNI), and a weekend that sees both the Bitcoin Ireland Conference and Aontú’s Ard Fheis, it’s clear momentum is building on the Emerald Isle.
A Sound Punt: A Paper for the Citizens of Ireland
The new paper, released today by Bitcoin Network Ireland, is a concise, accessible document crafted to cut through the noise and present the merits of Bitcoin to the general public and politicians alike. Its aim is straightforward: provide a rational, jargon-free entry point into why Bitcoin matters, especially in an era of euro debasement and rising living costs.
The name itself is a clever pun—while it is a nod to both “sound money” and Ireland’s former currency, the punt, it also playfully suggests that although the majority of people view it as associated with risk, this may be worth reevaluating. It’s a signal that this is about more than technology: it’s about claiming monetary sovereignty and re-examining what makes money “good” in the first place.
What BNI is attempting to accomplish is bridging an important gap in understanding, helping citizens seeking change and government officials looking for solutions to recognize that sound, stateless money has value for everyone. As Mark Goodwin famously noted, “Bitcoin simply must be for enemies, or it will never be for friends.“—a neutral system that serves all participants regardless of their political stance.
Ireland’s Long and Complicated Relationship With Money
To appreciate the significance of this moment, it’s worth noting that Ireland’s relationship with money has always been distinct from its European neighbors. While the Romans introduced coinage to Britain over a thousand years before it was adopted in Ireland. The native Irish resisted state-issued money, relying instead on barter and bullion well into the second millennium.
In ancient Ireland, the absence of coinage was a testament to a society that was stateless, highly decentralised, and it embraced a polycentric legal system varying between clans. The ideal of that society was that no man in society has rule over others, and even kings could be disposed of if they abused their power.
So it’s perhaps no coincidence that Ireland was the last European society to adopt coinage, as coinage gives power to rulers. Eventually, it was forced upon the land by the English crown in 1601, this period coincided with the final stages of the Nine Years’ War (1594-1603) and the increasing English control over Ireland. To this day, Ireland has never had its own free-floating currency; it has always been tethered to external powers: first the pound sterling, then the European Monetary System, and now the euro under the ECB. So it should come as no coincidence that in recent years, the EU is growing unabated in power and influence over Ireland.
“Give me control over a nation’s currency, and I care not who makes its laws.” — Mayer Amschel Rothschild (1743–1812)
Perhaps, given this historical context, Ireland is uniquely positioned to understand the value of sound, stateless money. Bitcoin represents a return to the monetary independence that preceded state-issued currencies, but with the technological advantages of the digital age. Where ancient Irish kingdoms used market goods that couldn’t be manipulated by distant authorities, Bitcoin offers a modern equivalent: a system that can’t be debased or controlled by any power, whether domestic or foreign.
This historical skepticism toward centrally-controlled currency is resurfacing in the present, as the Irish state and its citizens face a new wave of economic uncertainty via euro debasement and tariffs. Geopolitical and economic tensions have rarely felt less stable. Tariff disputes, renewed questions over Ireland’s foreign direct-investment model, and potential tech and pharma layoffs are sure to sharpen the focus on sovereignty and resilience. The release of “A Sound Punt” is timely, inviting the nation to once again question the wisdom of tying its fortunes to distant monetary authorities.
A Political Crossroads
Coinciding with the release of “A Sound Punt,” Dr. Niall Burke—a respected academic and BNI member—will be putting forward two motions at the Aontú Ard Fheis (party conference). Aontú, the party that saw the largest surge in votes in the last general election, has shown itself to be receptive to Bitcoin and is opening its doors to conversations that, until recently, were relegated to the margins. That Bitcoin motions are being presented and accepted at a major party conference is a marker of how the conversation is turning.
Meanwhile, the Bitcoin Ireland Conference is gathering the country’s growing community of plebs, builders, and advocates. These circles, once on the periphery, are now finding doors opening in political circles.
Public Discontent and a Call for Financial Autonomy
It’s not just Bitcoiners who are seeking alternatives. Ireland is witnessing its largest public demonstrations since the post-GFC days of 2012. Recent marches have drawn in excess of 100,000 people to the streets of Dublin. These protests reflect deep frustration and a sense that the political establishment is no longer in alignment with its people.
What’s particularly striking is how Bitcoin could serve as common ground for seemingly opposing interests. For protesters, Bitcoin offers protection from inflation and defends against government overreach. For a government concerned about economic stability and growth, Bitcoin may be the very solution it needs, especially to protect pension funds and indeed the state’s very own investment fund—ISIF, from inflation over the coming decades. This is the paradox and promise of sound, stateless money. It serves everyone’s interests because it enforces property rights, and can’t be captured or controlled by any single faction.
Last, but not least, MMA star Conor McGregor’s foray into both politics and Bitcoin is something few would have predicted a year ago, but for those with an ear to the ground, this has been a developing story for some time. His proposal for a national Bitcoin reserve is emblematic of a broader national shift: Bitcoin is finally entering the Zeitgeist and perhaps he, like BNI, has a part to play in keeping it there.
Bitcoin is an open-source monetary protocol, and adoption comes from all quarters, irrespective of politics. Bitcoin is neutral, it supports no partisan cause. What’s perhaps not recognized enough is how empowering Bitcoin can be and we should focus on its ability to unite rather than divide, giving every Irish citizen—regardless of their political views—tools for individual liberty, inflation protection, as well as practical solutions for businesses.
Back to “A Sound Punt” Paper
The paper itself makes a compelling case for Ireland’s interest in Bitcoin:
- Sound Money Principles: It evaluates Bitcoin against the six characteristics of “good money”—durability, divisibility, uniformity, portability, verifiability, and scarcity.
- Store of Value: The document highlights Bitcoin’s fixed supply as protection against rising inflation and currency debasement.
- Practical Examples: It provides evidence of Bitcoin’s monetization, comparing the costs of buying a home in Euros vs. Bitcoin over the span of a decade.
- Common Concern Rebuttals: The paper addresses the most common objections to Bitcoin—energy usage, volatility, criminal activity, undermining traditional currencies, and speculation—offering balanced counterarguments to each.
- Action Steps: Rather than just theoretical arguments, the paper outlines specific actions for individuals, businesses, and the government to consider, from education to strategic Bitcoin reserves.
The Beginning of a Process
No one expects the Irish government to announce a Bitcoin treasury next week, and it’s debatable whether it should establish one at all. But “A Sound Punt” marks the beginning of a process that could, in time, help reshape Ireland’s approach to money and economic sovereignty.
This accessible primer is just the first step in Bitcoin Network Ireland’s broader educational mission. BNI plans to publish a much more comprehensive policy paper for policymakers in the coming months, which is currently going through the editing phase. While “A Sound Punt” introduces the concepts to the general public, the forthcoming document will provide the detailed analysis and policy recommendations that decision-makers need.

2025-02-18 20:30:32For the last couple of weeks, I've been dealing with the fallout of upgrading a web application to Svelte 5. Complaints about framework churn and migration annoyances aside, I've run into some interesting issues with the migration. So far, I haven't seen many other people register the same issues, so I thought it might be constructive for me to articulate them myself.
I'll try not to complain too much in this post, since I'm grateful for the many years of Svelte 3/4 I've enjoyed. But I don't think I'll be choosing Svelte for any new projects going forward. I hope my reflections here will be useful to others as well.
If you're interested in reproductions for the issues I mention here, you can find them below.
The Need for Speed
To start with, let me just quickly acknowledge what the Svelte team is trying to do. It seems like most of the substantial changes in version 5 are built around "deep reactivity", which allows for more granular reactivity, leading to better performance. Performance is good, and the Svelte team has always excelled at reconciling performance with DX.
In previous versions of Svelte, the main way this was achieved was with the Svelte compiler. There were many ancillary techniques involved in improving performance, but having a framework compile step gave the Svelte team a lot of leeway for rearranging things under the hood without making developers learn new concepts. This is what made Svelte so original in the beginning.
At the same time, it resulted in an even more opaque framework than usual, making it harder for developers to debug more complex issues. To make matters worse, the compiler had bugs, resulting in errors which could only be fixed by blindly refactoring the problem component. This happened to me personally at least half a dozen times, and is what ultimately pushed me to migrate to Svelte 5.
Nevertheless, I always felt it was an acceptable trade-off for speed and productivity. Sure, sometimes I had to delete my project and port it to a fresh repository every so often, but the framework was truly a pleasure to use.
Svelte is not Javascript
Svelte 5 doubled down on this tradeoff — which makes sense, because it's what sets the framework apart. The difference this time is that the abstraction/performance tradeoff did not stay in compiler land, but intruded into runtime in two important ways:
- The use of proxies to support deep reactivity
- Implicit component lifecycle state
Both of these changes improved performance and made the API for developers look slicker. What's not to like? Unfortunately, both of these features are classic examples of a leaky abstraction, and ultimately make things more complex for developers, not less.
Proxies are not objects
The use of proxies seems to have allowed the Svelte team to squeeze a little more performance out of the framework, without asking developers to do any extra work. Threading state through multiple levels of components without provoking unnecessary re-renders in frameworks like React is an infamously difficult chore.
Svelte's compiler avoided some of the pitfalls associated with virtual DOM diffing solutions, but evidently there was still enough of a performance gain to be had to justify the introduction of proxies. The Svelte team also seems to argue that their introduction represents an improvement in developer experience:
we... can maximise both efficiency and ergonomics.
Here's the problem: Svelte 5 looks simpler, but actually introduces more abstractions.
Using proxies to monitor array methods (for example) is appealing because it allows developers to forget all the goofy heuristics involved with making sure state was reactive and just
push
to the array. I can't count how many times I've writtenvalue = value
to trigger reactivity in svelte 4.In Svelte 4, developers had to understand how the Svelte compiler worked. The compiler, being a leaky abstraction, forced its users to know that assignment was how you signaled reactivity. In svelte 5, developers can just "forget" about the compiler!
Except they can't. All the introduction of new abstractions really accomplishes is the introduction of more complex heuristics that developers have to keep in their heads in order to get the compiler to act the way they want it to.
In fact, this is why after years of using Svelte, I found myself using Svelte stores more and more often, and reactive declarations less. The reason being that Svelte stores are just javascript. Calling
update
on a store is simple, and being able to reference them with a$
was just a nice bonus — nothing to remember, and if I mess up the compiler yells at me.Proxies introduce a similar problem to reactive declarations, which is that they look like one thing but act like another on the edges.
When I started using Svelte 5, everything worked great — until I tried to save a proxy to indexeddb, at which point I got a
DataCloneError
. To make matters worse, it's impossible to reliably tell if something is aProxy
withouttry/catch
ing a structured clone, which is a performance-intensive operation.This forces the developer to remember what is and what isn't a Proxy, calling
$state.snapshot
every time they pass a proxy to a context that doesn't expect or know about them. This obviates all the nice abstractions they gave us in the first place.Components are not functions
The reason virtual DOM took off way back in 2013 was the ability to model your application as composed functions, each of which takes data and spits out HTML. Svelte retained this paradigm, using a compiler to sidestep the inefficiencies of virtual DOM and the complexities of lifecycle methods.
In Svelte 5, component lifecycles are back, react-hooks style.
In React, hooks are an abstraction that allows developers to avoid writing all the stateful code associated with component lifecycle methods. Modern React tutorials universally recommend using hooks instead, which rely on the framework invisibly synchronizing state with the render tree.
While this does result in cleaner code, it also requires developers to tread carefully to avoid breaking the assumptions surrounding hooks. Just try accessing state in a
setTimeout
and you'll see what I mean.Svelte 4 had a few gotchas like this — for example, async code that interacts with a component's DOM elements has to keep track of whether the component is unmounted. This is pretty similar to the kind of pattern you'd see in old React components that relied on lifecycle methods.
It seems to me that Svelte 5 has gone the React 16 route by adding implicit state related to component lifecycles in order to coordinate state changes and effects.
For example, here is an excerpt from the documentation for $effect:
You can place $effect anywhere, not just at the top level of a component, as long as it is called during component initialization (or while a parent effect is active). It is then tied to the lifecycle of the component (or parent effect) and will therefore destroy itself when the component unmounts (or the parent effect is destroyed).
That's very complex! In order to use
$effect
... effectively (sorry), developers have to understand how state changes are tracked. The documentation for component lifecycles claims:In Svelte 5, the component lifecycle consists of only two parts: Its creation and its destruction. Everything in-between — when certain state is updated — is not related to the component as a whole; only the parts that need to react to the state change are notified. This is because under the hood the smallest unit of change is actually not a component, it’s the (render) effects that the component sets up upon component initialization. Consequently, there’s no such thing as a “before update”/"after update” hook.
But then goes on to introduce the idea of
tick
in conjunction with$effect.pre
. This section explains that "tick
returns a promise that resolves once any pending state changes have been applied, or in the next microtask if there are none."I'm sure there's some mental model that justifies this, but I don't think the claim that a component's lifecycle is only comprised of mount/unmount is really helpful when an addendum about state changes has to come right afterward.
The place where this really bit me, and which is the motivation for this blog post, is when state gets coupled to a component's lifecycle, even when the state is passed to another function that doesn't know anything about svelte.
In my application, I manage modal dialogs by storing the component I want to render alongside its props in a store and rendering it in the
layout.svelte
of my application. This store is also synchronized with browser history so that the back button works to close them. Sometimes, it's useful to pass a callback to one of these modals, binding caller-specific functionality to the child component:javascript const {value} = $props() const callback = () => console.log(value) const openModal = () => pushModal(MyModal, {callback})
This is a fundamental pattern in javascript. Passing a callback is just one of those things you do.
Unfortunately, if the above code lives in a modal dialog itself, the caller component gets unmounted before the callback gets called. In Svelte 4, this worked fine, but in Svelte 5
value
gets updated toundefined
when the component gets unmounted. Here's a minimal reproduction.This is only one example, but it seems clear to me that any prop that is closed over by a callback function that lives longer than its component will be undefined when I want to use it — with no reassignment existing in lexical scope. It seems that the reason this happens is that the props "belong" to the parent component, and are accessed via getters so that the parent can revoke access when it unmounts.
I don't know why this is necessary, but I assume there's a good engineering reason for it. The problem is, this just isn't how javascript works. Svelte is essentially attempting to re-invent garbage collection around component lifecycles, which breaks the assumption every javascript developer has that variables don't simply disappear without an explicit reassignment. It should be safe to pass stuff around and let the garbage collector do its job.
Conclusion
Easy things are nice, but as Rich Hickey says, easy things are not always simple. And like Joel Spolsky, I don't like being surprised. Svelte has always been full of magic, but with the latest release I think the cognitive overhead of reciting incantations has finally outweighed the power it confers.
My point in this post is not to dunk on the Svelte team. I know lots of people like Svelte 5 (and react hooks). The point I'm trying to make is that there is a tradeoff between doing things on the user's behalf, and giving the user agency. Good software is built on understanding, not cleverness.
I also think this is an important lesson to remember as AI-assisted coding becomes increasingly popular. Don't choose tools that alienate you from your work. Choose tools that leverage the wisdom you've already accumulated, and which help you to cultivate a deeper understanding of the discipline.
Thank you to Rich Harris and team for many years of pleasant development. I hope that (if you read this) it's not so full of inaccuracies as to be unhelpful as user feedback.

What to expect from the BTCfi & L2s companies at the Bitcoin Conference in VegasThe annual Bitcoin Conference in Las Vegas is a pivotal event for the Bitcoin ecosystem, where companies unveil breakthroughs, announce partnerships, and deliver speeches that shape the narrative of digital assets. For many, the sheer volume of information can be overwhelming. Having attended several conferences and being familiar with the attending companies through my work at UTXO, I’ve highlighted key panels and expected developments for 2025, focusing on Bitcoin’s Layer 2 (L2) and BTCfi ecosystems.
The full agenda is available using this link: https://b.tc/conference/2025/agenda
Here’s a breakdown of anticipated announcements and panels, categorized by key themes:
BitVM2 Announcements
Since BitVM’s introduction in 2023, top Bitcoin development teams have been working tirelessly to transform centralized sidechain designs into true Bitcoin rollups and permissionless L2s. At the 2025 conference, expect these teams to unveil the first versions of BitVM2 bridges, providing critical details on their mechanics. Once live, BitVM2 bridges could unlock a wide range of decentralized BTC use cases, accessible to all Bitcoin holders. May 2025 might mark a turning point, potentially signaling the decline of centralized “crypto” and DeFi projects in favor of a Bitcoin-native economy. As the saying goes, on a long enough timeline, everything comes back to Bitcoin.
L2 Partnerships
Bitcoin L2s face a steep challenge: competing with established crypto players while earning the trust of Bitcoiners. The conference is likely to feature major partnership announcements, particularly at the infrastructure level, addressing long-standing barriers to BTCfi adoption. These collaborations could bolster the credibility and functionality of L2 solutions, paving the way for broader acceptance.
Lightning and Taproot Assets Innovation
The recent announcement that Tether (USDT) will return to Bitcoin by issuing its stablecoin on Lightning rails via Taproot Assets has sparked significant excitement. Expect major updates from companies in this space, particularly regarding Taproot Assets and stablecoin integration. The Lightning Network is poised for dominance, and 2025 could be the year it breaks into the mainstream.
Opcodes and Governance Discussions
With growing support for covenant activation on Bitcoin and recent debates over mempool policy on social media, governance discussions will be a focal point. These panels promise to be intellectually stimulating, offering deep insights into Bitcoin’s core mechanics and potential fireworks for those following the debates. Attending these sessions will likely be the most rewarding experience of the week for anyone seeking to understand Bitcoin’s future.
Must-Attend Panels
Below is a curated list of panels aligned with the above categories, along with my expectations for each. (Note: These predictions reflect my personal perspective and are not definitive. This list is not exhaustive but highlights high-signal sessions for attendees with limited time.)
Panels and Keynote with the highest probability of a major announcement related to Bitcoin L2s and BTCfi products: in other words, this is where major alpha will be dropped

2025-02-17 17:12:01President Trump has intensified immigration enforcement, likening it to a wartime effort. Despite pouring resources into the U.S. Immigration and Customs Enforcement (ICE), arrest numbers are declining and falling short of goals. ICE fell from about 800 daily arrests in late January to fewer than 600 in early February.
Critics argue the administration is merely showcasing efforts with ineffectiveness, while Trump seeks billions more in funding to support his deportation agenda. Increased involvement from various federal agencies is intended to assist ICE, but many lack specific immigration training.
Challenges persist, as fewer immigrants are available for quick deportation due to a decline in illegal crossings. Local sheriffs are also pressured by rising demands to accommodate immigrants, which may strain resources further.

2024-12-12 11:43:36The Peano axioms are a set of rules that define the natural numbers (like 0, 1, 2, 3, and so on) in a logical way. Here’s a simplified explanation: 1. There is a first number: There is a number called zero, and it is the starting point for all natural numbers. 2. Each number has a next number: Every number has a unique “successor,” or the number that comes after it (like 1 comes after 0, 2 comes after 1, etc.). 3. Zero is special: Zero is not the “next” number of any other number. This means the sequence of natural numbers doesn’t loop back to zero. 4. No two numbers are the same if they have different successors: If two numbers have the same “next” number, then they must actually be the same number. 5. Patterns hold for all numbers: If something is true for zero, and it stays true when moving from one number to the next, then it must be true for all numbers.
These principles lay the groundwork for understanding and working with the natural numbers systematically.

2025-02-15 07:02:08E-cash are coupons or tokens for Bitcoin, or Bitcoin debt notes that the mint issues. The e-cash states, essentially, "IoU 2900 sats".
They're redeemable for Bitcoin on Lightning (hard money), and therefore can be used as cash (softer money), so long as the mint has a good reputation. That means that they're less fungible than Lightning because the e-cash from one mint can be more or less valuable than the e-cash from another. If a mint is buggy, offline, or disappears, then the e-cash is unreedemable.
It also means that e-cash is more anonymous than Lightning, and that the sender and receiver's wallets don't need to be online, to transact. Nutzaps now add the possibility of parking transactions one level farther out, on a relay. The same relays that cannot keep npub profiles and follow lists consistent will now do monetary transactions.
What we then have is * a transaction on a relay that triggers * a transaction on a mint that triggers * a transaction on Lightning that triggers * a transaction on Bitcoin.
Which means that every relay that stores the nuts is part of a wildcat banking system. Which is fine, but relay operators should consider whether they wish to carry the associated risks and liabilities. They should also be aware that they should implement the appropriate features in their relay, such as expiration tags (nuts rot after 2 weeks), and to make sure that only expired nuts are deleted.
There will be plenty of specialized relays for this, so don't feel pressured to join in, and research the topic carefully, for yourself.

Trump Media Group Seeks $3 Billion War Chest to Buy Bitcoin and Crypto Assets: FTTrump Media and Technology Group (TMTG), the company behind Truth Social and controlled by the Trump family, is preparing to raise a staggering $3 billion to invest in cryptocurrencies such as Bitcoin, according to the Financial Times.
JUST IN:
Trump Media Group to raise $3 billion to buy Bitcoin and crypto — Financial Times pic.twitter.com/VEyvy5vpGZ
— Bitcoin Magazine (@BitcoinMagazine) May 26, 2025
The media venture plans to secure $2 billion in fresh equity and another $1 billion through a convertible bond offering, those familiar with the matter told the Financial Times. The capital raise could be formally announced ahead of The Bitcoin 2025 Conference in Las Vegas this week, where Vice President JD Vance, Donald Trump Jr., Eric Trump, and Trump’s crypto advisor David Sachs are expected to speak.
The secondary equity offering will be carried out on an at-the-market basis, meaning shares are expected to be priced near the most recent closing price of $25.72, giving TMTG a current valuation of nearly $6 billion.
TMTG’s push comes amid a wider cryptocurrency resurgence. Bitcoin hit a new record of $111,999 last week, and investor interest in crypto-related plays has surged. The strategy echoes that of Strategy, which used a similar blend of debt and equity financing to buy tens of billions of dollars in Bitcoin—catapulting its market cap to over $100 billion.
Although the news is still yet to be confirmed by TMTG, a comment they made to the Financial Times may give some doubt to the validity of the story:
“Apparently the Financial Times has dumb writers listening to even dumber sources”, reportedly said TMTG. A White House spokesperson also declined to weigh in. Representatives for Donald Trump Jr. did not respond to requests for comment and Reuters also did not immediately receive a request for comment.
TMTG’s deepening crypto pivot has included a slew of ventures: an NFT trading card series, two memecoins, investments in crypto miner American Bitcoin and stablecoin platform World Liberty Financial, and an upcoming crypto ETF.
After returning to the White House last year, Trump transferred his 53% stake in TMTG—worth roughly $3 billion—to a revocable trust controlled by Donald Trump Jr., who holds full investment and voting authority.
This is a developing story and will be updated as needed.

2024-12-08 10:52:55Power as the Reduction of Possibilities: Niklas Luhmann’s Perspective
Niklas Luhmann, a leading figure in systems theory, offers a unique conceptualization of power that diverges from traditional notions of domination or coercion. Rather than viewing power as a forceful imposition of will, Luhmann frames it as a mechanism for reducing possibilities within a given social system. For Luhmann, power is less about direct coercion and more about structuring decision-making processes by limiting the range of available options.
In his systems-theoretical approach, Luhmann argues that power operates as a communication medium, enabling complex social systems to function by simplifying the overwhelming array of potential actions. In any decision-making context, there are countless possibilities, and not all can be pursued. Power serves as a tool to focus attention, filter alternatives, and channel behavior toward specific actions while excluding others. This reduction of options creates a manageable environment for coordinated action, which is essential for the stability of a system.
Importantly, this process does not inherently involve force or threats. Instead, power works through expectations, norms, and structures that guide behavior. For example, in an organizational setting, the hierarchy of authority determines which decisions are permissible, thereby shaping the actions of individuals without overt coercion. The employees’ actions are not forced; rather, they are conditioned by the organizational framework, which narrows their choices.
Luhmann’s idea redefines power as a productive force in social systems. By limiting possibilities, power reduces uncertainty, making collaboration and collective action possible. It ensures that systems can function efficiently despite their inherent complexity. This perspective shifts the emphasis from conflict to coordination, offering a more nuanced understanding of how power operates in modern societies.
In sum, Niklas Luhmann’s theory of power as the reduction of possibilities highlights its integrative role in enabling social systems to navigate complexity. It challenges conventional views of power as coercion, emphasizing its capacity to organize and stabilize interactions through the selective limitation of actions.

2025-01-21 01:51:46Bitcoin: Um sistema de dinheiro eletrônico direto entre pessoas.
Satoshi Nakamoto
satoshin@gmx.com
www.bitcoin.org
Resumo
O Bitcoin é uma forma de dinheiro digital que permite pagamentos diretos entre pessoas, sem a necessidade de um banco ou instituição financeira. Ele resolve um problema chamado gasto duplo, que ocorre quando alguém tenta gastar o mesmo dinheiro duas vezes. Para evitar isso, o Bitcoin usa uma rede descentralizada onde todos trabalham juntos para verificar e registrar as transações.
As transações são registradas em um livro público chamado blockchain, protegido por uma técnica chamada Prova de Trabalho. Essa técnica cria uma cadeia de registros que não pode ser alterada sem refazer todo o trabalho já feito. Essa cadeia é mantida pelos computadores que participam da rede, e a mais longa é considerada a verdadeira.
Enquanto a maior parte do poder computacional da rede for controlada por participantes honestos, o sistema continuará funcionando de forma segura. A rede é flexível, permitindo que qualquer pessoa entre ou saia a qualquer momento, sempre confiando na cadeia mais longa como prova do que aconteceu.
1. Introdução
Hoje, quase todos os pagamentos feitos pela internet dependem de bancos ou empresas como processadores de pagamento (cartões de crédito, por exemplo) para funcionar. Embora esse sistema seja útil, ele tem problemas importantes porque é baseado em confiança.
Primeiro, essas empresas podem reverter pagamentos, o que é útil em caso de erros, mas cria custos e incertezas. Isso faz com que pequenas transações, como pagar centavos por um serviço, se tornem inviáveis. Além disso, os comerciantes são obrigados a desconfiar dos clientes, pedindo informações extras e aceitando fraudes como algo inevitável.
Esses problemas não existem no dinheiro físico, como o papel-moeda, onde o pagamento é final e direto entre as partes. No entanto, não temos como enviar dinheiro físico pela internet sem depender de um intermediário confiável.
O que precisamos é de um sistema de pagamento eletrônico baseado em provas matemáticas, não em confiança. Esse sistema permitiria que qualquer pessoa enviasse dinheiro diretamente para outra, sem depender de bancos ou processadores de pagamento. Além disso, as transações seriam irreversíveis, protegendo vendedores contra fraudes, mas mantendo a possibilidade de soluções para disputas legítimas.
Neste documento, apresentamos o Bitcoin, que resolve o problema do gasto duplo usando uma rede descentralizada. Essa rede cria um registro público e protegido por cálculos matemáticos, que garante a ordem das transações. Enquanto a maior parte da rede for controlada por pessoas honestas, o sistema será seguro contra ataques.
2. Transações
Para entender como funciona o Bitcoin, é importante saber como as transações são realizadas. Imagine que você quer transferir uma "moeda digital" para outra pessoa. No sistema do Bitcoin, essa "moeda" é representada por uma sequência de registros que mostram quem é o atual dono. Para transferi-la, você adiciona um novo registro comprovando que agora ela pertence ao próximo dono. Esse registro é protegido por um tipo especial de assinatura digital.
O que é uma assinatura digital?
Uma assinatura digital é como uma senha secreta, mas muito mais segura. No Bitcoin, cada usuário tem duas chaves: uma "chave privada", que é secreta e serve para criar a assinatura, e uma "chave pública", que pode ser compartilhada com todos e é usada para verificar se a assinatura é válida. Quando você transfere uma moeda, usa sua chave privada para assinar a transação, provando que você é o dono. A próxima pessoa pode usar sua chave pública para confirmar isso.
Como funciona na prática?
Cada "moeda" no Bitcoin é, na verdade, uma cadeia de assinaturas digitais. Vamos imaginar o seguinte cenário:
- A moeda está com o Dono 0 (você). Para transferi-la ao Dono 1, você assina digitalmente a transação com sua chave privada. Essa assinatura inclui o código da transação anterior (chamado de "hash") e a chave pública do Dono 1.
- Quando o Dono 1 quiser transferir a moeda ao Dono 2, ele assinará a transação seguinte com sua própria chave privada, incluindo também o hash da transação anterior e a chave pública do Dono 2.
- Esse processo continua, formando uma "cadeia" de transações. Qualquer pessoa pode verificar essa cadeia para confirmar quem é o atual dono da moeda.
Resolvendo o problema do gasto duplo
Um grande desafio com moedas digitais é o "gasto duplo", que é quando uma mesma moeda é usada em mais de uma transação. Para evitar isso, muitos sistemas antigos dependiam de uma entidade central confiável, como uma casa da moeda, que verificava todas as transações. No entanto, isso criava um ponto único de falha e centralizava o controle do dinheiro.
O Bitcoin resolve esse problema de forma inovadora: ele usa uma rede descentralizada onde todos os participantes (os "nós") têm acesso a um registro completo de todas as transações. Cada nó verifica se as transações são válidas e se a moeda não foi gasta duas vezes. Quando a maioria dos nós concorda com a validade de uma transação, ela é registrada permanentemente na blockchain.
Por que isso é importante?
Essa solução elimina a necessidade de confiar em uma única entidade para gerenciar o dinheiro, permitindo que qualquer pessoa no mundo use o Bitcoin sem precisar de permissão de terceiros. Além disso, ela garante que o sistema seja seguro e resistente a fraudes.
3. Servidor Timestamp
Para assegurar que as transações sejam realizadas de forma segura e transparente, o sistema Bitcoin utiliza algo chamado de "servidor de registro de tempo" (timestamp). Esse servidor funciona como um registro público que organiza as transações em uma ordem específica.
Ele faz isso agrupando várias transações em blocos e criando um código único chamado "hash". Esse hash é como uma impressão digital que representa todo o conteúdo do bloco. O hash de cada bloco é amplamente divulgado, como se fosse publicado em um jornal ou em um fórum público.
Esse processo garante que cada bloco de transações tenha um registro de quando foi criado e que ele existia naquele momento. Além disso, cada novo bloco criado contém o hash do bloco anterior, formando uma cadeia contínua de blocos conectados — conhecida como blockchain.
Com isso, se alguém tentar alterar qualquer informação em um bloco anterior, o hash desse bloco mudará e não corresponderá ao hash armazenado no bloco seguinte. Essa característica torna a cadeia muito segura, pois qualquer tentativa de fraude seria imediatamente detectada.
O sistema de timestamps é essencial para provar a ordem cronológica das transações e garantir que cada uma delas seja única e autêntica. Dessa forma, ele reforça a segurança e a confiança na rede Bitcoin.
4. Prova-de-Trabalho
Para implementar o registro de tempo distribuído no sistema Bitcoin, utilizamos um mecanismo chamado prova-de-trabalho. Esse sistema é semelhante ao Hashcash, desenvolvido por Adam Back, e baseia-se na criação de um código único, o "hash", por meio de um processo computacionalmente exigente.
A prova-de-trabalho envolve encontrar um valor especial que, quando processado junto com as informações do bloco, gere um hash que comece com uma quantidade específica de zeros. Esse valor especial é chamado de "nonce". Encontrar o nonce correto exige um esforço significativo do computador, porque envolve tentativas repetidas até que a condição seja satisfeita.
Esse processo é importante porque torna extremamente difícil alterar qualquer informação registrada em um bloco. Se alguém tentar mudar algo em um bloco, seria necessário refazer o trabalho de computação não apenas para aquele bloco, mas também para todos os blocos que vêm depois dele. Isso garante a segurança e a imutabilidade da blockchain.
A prova-de-trabalho também resolve o problema de decidir qual cadeia de blocos é a válida quando há múltiplas cadeias competindo. A decisão é feita pela cadeia mais longa, pois ela representa o maior esforço computacional já realizado. Isso impede que qualquer indivíduo ou grupo controle a rede, desde que a maioria do poder de processamento seja mantida por participantes honestos.
Para garantir que o sistema permaneça eficiente e equilibrado, a dificuldade da prova-de-trabalho é ajustada automaticamente ao longo do tempo. Se novos blocos estiverem sendo gerados rapidamente, a dificuldade aumenta; se estiverem sendo gerados muito lentamente, a dificuldade diminui. Esse ajuste assegura que novos blocos sejam criados aproximadamente a cada 10 minutos, mantendo o sistema estável e funcional.
5. Rede
A rede Bitcoin é o coração do sistema e funciona de maneira distribuída, conectando vários participantes (ou nós) para garantir o registro e a validação das transações. Os passos para operar essa rede são:
-
Transmissão de Transações: Quando alguém realiza uma nova transação, ela é enviada para todos os nós da rede. Isso é feito para garantir que todos estejam cientes da operação e possam validá-la.
-
Coleta de Transações em Blocos: Cada nó agrupa as novas transações recebidas em um "bloco". Este bloco será preparado para ser adicionado à cadeia de blocos (a blockchain).
-
Prova-de-Trabalho: Os nós competem para resolver a prova-de-trabalho do bloco, utilizando poder computacional para encontrar um hash válido. Esse processo é como resolver um quebra-cabeça matemático difícil.
-
Envio do Bloco Resolvido: Quando um nó encontra a solução para o bloco (a prova-de-trabalho), ele compartilha esse bloco com todos os outros nós na rede.
-
Validação do Bloco: Cada nó verifica o bloco recebido para garantir que todas as transações nele contidas sejam válidas e que nenhuma moeda tenha sido gasta duas vezes. Apenas blocos válidos são aceitos.
-
Construção do Próximo Bloco: Os nós que aceitaram o bloco começam a trabalhar na criação do próximo bloco, utilizando o hash do bloco aceito como base (hash anterior). Isso mantém a continuidade da cadeia.
Resolução de Conflitos e Escolha da Cadeia Mais Longa
Os nós sempre priorizam a cadeia mais longa, pois ela representa o maior esforço computacional já realizado, garantindo maior segurança. Se dois blocos diferentes forem compartilhados simultaneamente, os nós trabalharão no primeiro bloco recebido, mas guardarão o outro como uma alternativa. Caso o segundo bloco eventualmente forme uma cadeia mais longa (ou seja, tenha mais blocos subsequentes), os nós mudarão para essa nova cadeia.
Tolerância a Falhas
A rede é robusta e pode lidar com mensagens que não chegam a todos os nós. Uma transação não precisa alcançar todos os nós de imediato; basta que chegue a um número suficiente deles para ser incluída em um bloco. Da mesma forma, se um nó não receber um bloco em tempo hábil, ele pode solicitá-lo ao perceber que está faltando quando o próximo bloco é recebido.
Esse mecanismo descentralizado permite que a rede Bitcoin funcione de maneira segura, confiável e resiliente, sem depender de uma autoridade central.
6. Incentivo
O incentivo é um dos pilares fundamentais que sustenta o funcionamento da rede Bitcoin, garantindo que os participantes (nós) continuem operando de forma honesta e contribuindo com recursos computacionais. Ele é estruturado em duas partes principais: a recompensa por mineração e as taxas de transação.
Recompensa por Mineração
Por convenção, o primeiro registro em cada bloco é uma transação especial que cria novas moedas e as atribui ao criador do bloco. Essa recompensa incentiva os mineradores a dedicarem poder computacional para apoiar a rede. Como não há uma autoridade central para emitir moedas, essa é a maneira pela qual novas moedas entram em circulação. Esse processo pode ser comparado ao trabalho de garimpeiros, que utilizam recursos para colocar mais ouro em circulação. No caso do Bitcoin, o "recurso" consiste no tempo de CPU e na energia elétrica consumida para resolver a prova-de-trabalho.
Taxas de Transação
Além da recompensa por mineração, os mineradores também podem ser incentivados pelas taxas de transação. Se uma transação utiliza menos valor de saída do que o valor de entrada, a diferença é tratada como uma taxa, que é adicionada à recompensa do bloco contendo essa transação. Com o passar do tempo e à medida que o número de moedas em circulação atinge o limite predeterminado, essas taxas de transação se tornam a principal fonte de incentivo, substituindo gradualmente a emissão de novas moedas. Isso permite que o sistema opere sem inflação, uma vez que o número total de moedas permanece fixo.
Incentivo à Honestidade
O design do incentivo também busca garantir que os participantes da rede mantenham um comportamento honesto. Para um atacante que consiga reunir mais poder computacional do que o restante da rede, ele enfrentaria duas escolhas:
- Usar esse poder para fraudar o sistema, como reverter transações e roubar pagamentos.
- Seguir as regras do sistema, criando novos blocos e recebendo recompensas legítimas.
A lógica econômica favorece a segunda opção, pois um comportamento desonesto prejudicaria a confiança no sistema, diminuindo o valor de todas as moedas, incluindo aquelas que o próprio atacante possui. Jogar dentro das regras não apenas maximiza o retorno financeiro, mas também preserva a validade e a integridade do sistema.
Esse mecanismo garante que os incentivos econômicos estejam alinhados com o objetivo de manter a rede segura, descentralizada e funcional ao longo do tempo.
7. Recuperação do Espaço em Disco
Depois que uma moeda passa a estar protegida por muitos blocos na cadeia, as informações sobre as transações antigas que a geraram podem ser descartadas para economizar espaço em disco. Para que isso seja possível sem comprometer a segurança, as transações são organizadas em uma estrutura chamada "árvore de Merkle". Essa árvore funciona como um resumo das transações: em vez de armazenar todas elas, guarda apenas um "hash raiz", que é como uma assinatura compacta que representa todo o grupo de transações.
Os blocos antigos podem, então, ser simplificados, removendo as partes desnecessárias dessa árvore. Apenas a raiz do hash precisa ser mantida no cabeçalho do bloco, garantindo que a integridade dos dados seja preservada, mesmo que detalhes específicos sejam descartados.
Para exemplificar: imagine que você tenha vários recibos de compra. Em vez de guardar todos os recibos, você cria um documento e lista apenas o valor total de cada um. Mesmo que os recibos originais sejam descartados, ainda é possível verificar a soma com base nos valores armazenados.
Além disso, o espaço ocupado pelos blocos em si é muito pequeno. Cada bloco sem transações ocupa apenas cerca de 80 bytes. Isso significa que, mesmo com blocos sendo gerados a cada 10 minutos, o crescimento anual em espaço necessário é insignificante: apenas 4,2 MB por ano. Com a capacidade de armazenamento dos computadores crescendo a cada ano, esse espaço continuará sendo trivial, garantindo que a rede possa operar de forma eficiente sem problemas de armazenamento, mesmo a longo prazo.
8. Verificação de Pagamento Simplificada
É possível confirmar pagamentos sem a necessidade de operar um nó completo da rede. Para isso, o usuário precisa apenas de uma cópia dos cabeçalhos dos blocos da cadeia mais longa (ou seja, a cadeia com maior esforço de trabalho acumulado). Ele pode verificar a validade de uma transação ao consultar os nós da rede até obter a confirmação de que tem a cadeia mais longa. Para isso, utiliza-se o ramo Merkle, que conecta a transação ao bloco em que ela foi registrada.
Entretanto, o método simplificado possui limitações: ele não pode confirmar uma transação isoladamente, mas sim assegurar que ela ocupa um lugar específico na cadeia mais longa. Dessa forma, se um nó da rede aprova a transação, os blocos subsequentes reforçam essa aceitação.
A verificação simplificada é confiável enquanto a maioria dos nós da rede for honesta. Contudo, ela se torna vulnerável caso a rede seja dominada por um invasor. Nesse cenário, um atacante poderia fabricar transações fraudulentas que enganariam o usuário temporariamente até que o invasor obtivesse controle completo da rede.
Uma estratégia para mitigar esse risco é configurar alertas nos softwares de nós completos. Esses alertas identificam blocos inválidos, sugerindo ao usuário baixar o bloco completo para confirmar qualquer inconsistência. Para maior segurança, empresas que realizam pagamentos frequentes podem preferir operar seus próprios nós, reduzindo riscos e permitindo uma verificação mais direta e confiável.
9. Combinando e Dividindo Valor
No sistema Bitcoin, cada unidade de valor é tratada como uma "moeda" individual, mas gerenciar cada centavo como uma transação separada seria impraticável. Para resolver isso, o Bitcoin permite que valores sejam combinados ou divididos em transações, facilitando pagamentos de qualquer valor.
Entradas e Saídas
Cada transação no Bitcoin é composta por:
- Entradas: Representam os valores recebidos em transações anteriores.
- Saídas: Correspondem aos valores enviados, divididos entre os destinatários e, eventualmente, o troco para o remetente.
Normalmente, uma transação contém:
- Uma única entrada com valor suficiente para cobrir o pagamento.
- Ou várias entradas combinadas para atingir o valor necessário.
O valor total das saídas nunca excede o das entradas, e a diferença (se houver) pode ser retornada ao remetente como troco.
Exemplo Prático
Imagine que você tem duas entradas:
- 0,03 BTC
- 0,07 BTC
Se deseja enviar 0,08 BTC para alguém, a transação terá:
- Entrada: As duas entradas combinadas (0,03 + 0,07 BTC = 0,10 BTC).
- Saídas: Uma para o destinatário (0,08 BTC) e outra como troco para você (0,02 BTC).
Essa flexibilidade permite que o sistema funcione sem precisar manipular cada unidade mínima individualmente.
Difusão e Simplificação
A difusão de transações, onde uma depende de várias anteriores e assim por diante, não representa um problema. Não é necessário armazenar ou verificar o histórico completo de uma transação para utilizá-la, já que o registro na blockchain garante sua integridade.
10. Privacidade
O modelo bancário tradicional oferece um certo nível de privacidade, limitando o acesso às informações financeiras apenas às partes envolvidas e a um terceiro confiável (como bancos ou instituições financeiras). No entanto, o Bitcoin opera de forma diferente, pois todas as transações são publicamente registradas na blockchain. Apesar disso, a privacidade pode ser mantida utilizando chaves públicas anônimas, que desvinculam diretamente as transações das identidades das partes envolvidas.
Fluxo de Informação
- No modelo tradicional, as transações passam por um terceiro confiável que conhece tanto o remetente quanto o destinatário.
- No Bitcoin, as transações são anunciadas publicamente, mas sem revelar diretamente as identidades das partes. Isso é comparável a dados divulgados por bolsas de valores, onde informações como o tempo e o tamanho das negociações (a "fita") são públicas, mas as identidades das partes não.
Protegendo a Privacidade
Para aumentar a privacidade no Bitcoin, são adotadas as seguintes práticas:
- Chaves Públicas Anônimas: Cada transação utiliza um par de chaves diferentes, dificultando a associação com um proprietário único.
- Prevenção de Ligação: Ao usar chaves novas para cada transação, reduz-se a possibilidade de links evidentes entre múltiplas transações realizadas pelo mesmo usuário.
Riscos de Ligação
Embora a privacidade seja fortalecida, alguns riscos permanecem:
- Transações multi-entrada podem revelar que todas as entradas pertencem ao mesmo proprietário, caso sejam necessárias para somar o valor total.
- O proprietário da chave pode ser identificado indiretamente por transações anteriores que estejam conectadas.
11. Cálculos
Imagine que temos um sistema onde as pessoas (ou computadores) competem para adicionar informações novas (blocos) a um grande registro público (a cadeia de blocos ou blockchain). Este registro é como um livro contábil compartilhado, onde todos podem verificar o que está escrito.
Agora, vamos pensar em um cenário: um atacante quer enganar o sistema. Ele quer mudar informações já registradas para beneficiar a si mesmo, por exemplo, desfazendo um pagamento que já fez. Para isso, ele precisa criar uma versão alternativa do livro contábil (a cadeia de blocos dele) e convencer todos os outros participantes de que essa versão é a verdadeira.
Mas isso é extremamente difícil.
Como o Ataque Funciona
Quando um novo bloco é adicionado à cadeia, ele depende de cálculos complexos que levam tempo e esforço. Esses cálculos são como um grande quebra-cabeça que precisa ser resolvido.
- Os “bons jogadores” (nós honestos) estão sempre trabalhando juntos para resolver esses quebra-cabeças e adicionar novos blocos à cadeia verdadeira.
- O atacante, por outro lado, precisa resolver quebra-cabeças sozinho, tentando “alcançar” a cadeia honesta para que sua versão alternativa pareça válida.
Se a cadeia honesta já está vários blocos à frente, o atacante começa em desvantagem, e o sistema está projetado para que a dificuldade de alcançá-los aumente rapidamente.
A Corrida Entre Cadeias
Você pode imaginar isso como uma corrida. A cada bloco novo que os jogadores honestos adicionam à cadeia verdadeira, eles se distanciam mais do atacante. Para vencer, o atacante teria que resolver os quebra-cabeças mais rápido que todos os outros jogadores honestos juntos.
Suponha que:
- A rede honesta tem 80% do poder computacional (ou seja, resolve 8 de cada 10 quebra-cabeças).
- O atacante tem 20% do poder computacional (ou seja, resolve 2 de cada 10 quebra-cabeças).
Cada vez que a rede honesta adiciona um bloco, o atacante tem que "correr atrás" e resolver mais quebra-cabeças para alcançar.
Por Que o Ataque Fica Cada Vez Mais Improvável?
Vamos usar uma fórmula simples para mostrar como as chances de sucesso do atacante diminuem conforme ele precisa "alcançar" mais blocos:
P = (q/p)^z
- q é o poder computacional do atacante (20%, ou 0,2).
- p é o poder computacional da rede honesta (80%, ou 0,8).
- z é a diferença de blocos entre a cadeia honesta e a cadeia do atacante.
Se o atacante está 5 blocos atrás (z = 5):
P = (0,2 / 0,8)^5 = (0,25)^5 = 0,00098, (ou, 0,098%)
Isso significa que o atacante tem menos de 0,1% de chance de sucesso — ou seja, é muito improvável.
Se ele estiver 10 blocos atrás (z = 10):
P = (0,2 / 0,8)^10 = (0,25)^10 = 0,000000095, (ou, 0,0000095%).
Neste caso, as chances de sucesso são praticamente nulas.
Um Exemplo Simples
Se você jogar uma moeda, a chance de cair “cara” é de 50%. Mas se precisar de 10 caras seguidas, sua chance já é bem menor. Se precisar de 20 caras seguidas, é quase impossível.
No caso do Bitcoin, o atacante precisa de muito mais do que 20 caras seguidas. Ele precisa resolver quebra-cabeças extremamente difíceis e alcançar os jogadores honestos que estão sempre à frente. Isso faz com que o ataque seja inviável na prática.
Por Que Tudo Isso é Seguro?
- A probabilidade de sucesso do atacante diminui exponencialmente. Isso significa que, quanto mais tempo passa, menor é a chance de ele conseguir enganar o sistema.
- A cadeia verdadeira (honesta) está protegida pela força da rede. Cada novo bloco que os jogadores honestos adicionam à cadeia torna mais difícil para o atacante alcançar.
E Se o Atacante Tentar Continuar?
O atacante poderia continuar tentando indefinidamente, mas ele estaria gastando muito tempo e energia sem conseguir nada. Enquanto isso, os jogadores honestos estão sempre adicionando novos blocos, tornando o trabalho do atacante ainda mais inútil.
Assim, o sistema garante que a cadeia verdadeira seja extremamente segura e que ataques sejam, na prática, impossíveis de ter sucesso.
12. Conclusão
Propusemos um sistema de transações eletrônicas que elimina a necessidade de confiança, baseando-se em assinaturas digitais e em uma rede peer-to-peer que utiliza prova de trabalho. Isso resolve o problema do gasto duplo, criando um histórico público de transações imutável, desde que a maioria do poder computacional permaneça sob controle dos participantes honestos. A rede funciona de forma simples e descentralizada, com nós independentes que não precisam de identificação ou coordenação direta. Eles entram e saem livremente, aceitando a cadeia de prova de trabalho como registro do que ocorreu durante sua ausência. As decisões são tomadas por meio do poder de CPU, validando blocos legítimos, estendendo a cadeia e rejeitando os inválidos. Com este mecanismo de consenso, todas as regras e incentivos necessários para o funcionamento seguro e eficiente do sistema são garantidos.

2025-05-27 01:45:49เราค่อยๆลำดับเรื่องราวเริ่มจากเบาๆกันก่อนนะครับ หากย้อนกลับไปในปี 2009 บนเส้นทางที่โลกกำลังสับสนระหว่างการกินที่อิงธรรมชาติกับแนวทางการเปลี่ยนแปลงอาหารแบบสุดขั้ว Ethan Brown ได้ก่อตั้งบริษัท Beyond Meat ขึ้นมา โดยมีจุดประสงค์ชัดเจนว่าอยากสร้าง "เนื้อจากพืช" ให้มีรสชาติ เนื้อสัมผัส และประสบการณ์ที่ใกล้เคียงกับเนื้อสัตว์จริงให้มากที่สุดเท่าที่จะทำได้ นี่คือภาพลวงตาที่ถูกสร้างขึ้นภายใต้ธงของความยั่งยืน แต่เบื้องลึกกลับแฝงความเงียบงันอยู่ใต้เงาเทคโนโลยี
Ethan Brown ไม่ใช่คนที่ตื่นเช้ามาแล้วอยากเปลี่ยนโลกในทันที เขาเติบโตมากับพ่อที่เป็นนักอนุรักษ์ธรรมชาติ มีฟาร์มโคนมเล็ก ๆ ให้ได้สัมผัสความจริงของเกษตรกรรมแบบดั้งเดิม เขาเรียนจบปริญญาตรีด้านประวัติศาสตร์และรัฐบาล ต่อด้วยปริญญาโทด้านนโยบายสาธารณะจาก University of Maryland และ MBA จาก Columbia University เขาเคยทำงานด้านนโยบายพลังงานทางเลือกที่ National Governors Association และบริษัท Ballard Power Systems ก่อนจะย้ายขั้วจากพลังงานสู่โปรตีนแทน
ช่วงหนึ่งเขาพูดใน TED ว่า “ผมมองเห็นว่าอาหารนั้นเชื่อมโยงกับสิ่งแวดล้อมและสุขภาพมนุษย์อย่างลึกซึ้ง แต่เราแทบไม่พูดถึงเรื่องนี้ในระดับระบบเลย” เขาเห็นว่าสัตว์คือ “เครื่องจักรแปลงโปรตีนจากพืชไปเป็นเนื้อ” ซึ่งเขาเชื่อว่ามัน “ไม่จำเป็นอีกต่อไปแล้ว” ในศตวรรษที่ 21
Beyond Meat ไม่ได้ใช้สูตรการต้มถั่วแล้วปั้นเป็นเบอร์เกอร์แบบบ้าน ๆ แต่ใช้กระบวนการแปรรูปที่ซับซ้อนระดับอุตสาหกรรมที่เรียกว่า High Moisture Extrusion (HME) ที่ต้องใช้เครื่องจักรเฉพาะราคาแพงมาก เพื่อดัดแปลงโปรตีนพืช เช่น ถั่วเหลือง ถั่วลันเตา ให้มีโครงสร้างเหมือนกล้ามเนื้อสัตว์ ทั้งเส้นใย ความชุ่มฉ่ำ และแรงต้านเมื่อกัด ซึ่งทั้งหมดนี้ไม่สามารถทำในครัวชาวบ้านได้ง่าย ๆ
บริษัทได้รับทุนสนับสนุนตั้งแต่ช่วงเริ่มต้นจากกลุ่มนักลงทุนที่มีอิทธิพลใน Silicon Valley เช่น Kleiner Perkins และ Obvious Corporation ของ Evan Williams ผู้ร่วมก่อตั้ง Twitter ก่อนจะขยายฐานนักลงทุนไปยัง Tyson Foods (ซึ่งเป็นบริษัทยักษ์ใหญ่ด้านเนื้อสัตว์ของสหรัฐฯ ที่ลงทุนใน Beyond Meat ก่อนจะถอนตัวภายหลัง) และนักแสดงฮอลลีวูดอย่าง Leonardo DiCaprio การเข้าระดมทุนในตลาดหุ้น (IPO) ปี 2019 ก็ยิ่งสร้างกระแสให้บริษัทกลายเป็นภาพตัวแทนของการกินอนาคตที่ยั่งยืน ทว่าในความหรูหรานั้น มีรอยร้าวแฝงอยู่เสมอ
ในขณะที่ภาพจำของ Beyond Meat ถูกวาดว่าเป็น “ทางรอดของโลก” และ “อาหารเพื่อสิ่งแวดล้อม” รัฐบาลสหรัฐฯ ก็สนับสนุนทิศทางนี้อย่างเงียบเชียบ ด้วยการอัดงบประมาณกว่า 125 ล้านดอลลาร์เข้าสู่อุตสาหกรรมโปรตีนทางเลือกผ่านโครงการต่าง ๆ เช่น หน่วยงานวิจัย USDA และกองทุนสนับสนุนมหาวิทยาลัยด้านเทคโนโลยีอาหาร ไม่ต่างจากรัฐบาลอิสราเอลที่ทุ่มงบกว่า 18 ล้านดอลลาร์ให้บริษัทเนื้อเพาะเลี้ยงแบบไม่มีอ้อมค้อม ทั้งหมดนี้กำลังสร้างระบบอาหารที่ไม่ต้องพึ่งดิน ไม่ต้องพึ่งแดด ไม่ต้องพึ่งเกษตรกร แต่ขึ้นอยู่กับโรงงานที่ควบคุมโดยบริษัทมหาชนเพียงไม่กี่เจ้า
เมื่อมองให้ลึกลงไป Beyond Meat ไม่ใช่แค่บริษัทอาหาร แต่คือจุดเริ่มต้นแรกๆของโลก ในด้านระบบนิเวศใหม่ที่ตัด “คนตัวเล็ก” ออกจากสมการเกษตรกรรมโดยสิ้นเชิง เกษตรกรจะไม่มีทางผลิต “เนื้อจากพืช” เหล่านี้ได้ด้วยตัวเอง เพราะต้องใช้เทคโนโลยีราคาแพง วัตถุดิบเฉพาะ และสูตรการแปรรูปที่ถูกจดสิทธิบัตรไว้หมดแล้ว ระบบอาหารจึงค่อย ๆ ถูกปิดตายภายใต้รั้วของลิขสิทธิ์ เหมือนโลกของซอฟต์แวร์ที่ไม่มีใครแตะต้องโค้ดต้นฉบับได้ ทุกคำที่เคี้ยวอาจกลายเป็นทรัพย์สินของใครบางคน และในวันที่ดินผืนสุดท้ายไม่ได้ปลูกพืช แต่กลายเป็นโรงงานสังเคราะห์โปรตีน นั่นแหละที่มนุษย์จะพบว่า ตนเองไม่ได้เป็น “ผู้ผลิตอาหาร” อีกต่อไป แต่กลายเป็น “ผู้บริโภค” ตลอดกาล
แม้ตัวเลขยอดขายของ Beyond Meat จะพุ่งขึ้นในช่วงแรกหลังเข้าตลาดหุ้น แต่เมื่อเวลาผ่านไป กลับสะท้อนความจริงที่น่าสนใจว่าสิ่งที่ดูเหมือนจะเป็นทางออกของโลก อาจไม่ใช่คำตอบที่ยั่งยืนเลยก็ได้
ในปี 2022 บริษัทประกาศลดพนักงานลง 19% และราคาหุ้นร่วงลงกว่า 80% จากจุดสูงสุด พร้อมกับข่าวคราวที่ส่อให้เห็นปัญหาด้านความปลอดภัยในสายการผลิต และยอดขายที่ไม่เติบโตตามเป้า แม้จะพยายามขยายตลาดอย่างต่อเนื่อง แต่คนทั่วไปเริ่มตระหนักว่า “เนื้อจากพืช” ที่แปรรูปหนักอาจไม่ใช่คำตอบของสุขภาพหรือสิ่งแวดล้อมอย่างที่เคยเชื่อ
ไม่เพียงเท่านั้น ผลการสำรวจในอเมริกาและยุโรปเริ่มชี้ว่า คนที่เคยทดลองกิน plant-based meat กลับไม่ซื้อซ้ำ โดยให้เหตุผลว่าไม่อร่อย แพง และไม่เชื่อว่าเป็นอาหารที่ดีต่อร่างกายจริง ๆ อีกทั้งบางรายถึงกับบอกว่ารู้สึกแปลกแยก เพราะอาหารที่มีส่วนผสมเยอะและชื่อส่วนประกอบที่อ่านไม่ออก มักทำให้คนรู้สึกว่าไม่ใช่อาหารธรรมชาติ ซึ่งขัดกับความตั้งใจเดิมที่อยากกินอาหารเพื่อสุขภาพ
คำว่า “ยั่งยืน” จึงไม่เพียงพอจะอธิบายได้ว่าอะไรคือสิ่งดีจริง ๆ เพราะหากความยั่งยืนนั้นหมายถึงการผูกขาด แปรรูป และบังคับให้ผู้คนต้องซื้ออาหารจากบริษัทไม่กี่แห่ง มันก็ไม่ได้ต่างอะไรกับการจำกัดอิสรภาพในจานข้าว อาหารที่แท้ควรเป็นของทุกคน เป็นสิทธิ์พื้นฐานที่มนุษย์ควรสร้างได้เอง ไม่ใช่ต้องลงทะเบียนซื้อกับห้างใหญ่ ๆ ผ่าน QR code ทุกมื้อ
ทุกวันนี้ Beyond Meat ยังไม่ถึงจุดตกต่ำที่สุด และยังมีโอกาสกลับมาได้เสมอ แต่สิ่งนึงที่เราต้องตระหนักเอาไว้คือ นี่ยังเป็นแค่ยักษ์เล็กไม่ใช่ยักษ์ใหญ่ เทคโนโลยีการสกัดโปรตีนพืชมาขยำเป็นรูปนั้น ณ วินาทีนี้ คือโบราณเกินไปแล้วครับ ในตลาดก็มีหมูปลอมเนื้อปลอมแบบนี้ออกมามากมาย หน้าตางดงามสมจริง แต่สิ่งเหล่านี้มันคือแค่จุดเริ่มต้นครับ ถ้าจะนับเรื่องราวเหล่านี้ว่าเริ่มจาก 2009 ก็ไม่ผิดนัก
เมื่อถึงจุดหนึ่ง คุณจะมองเห็นลำดับชั้นของ ธุรกิจ นวตกรรม การครอบงำทางการตลาดแบบผูกมัดที่ตัดแขนตัดขาไปทีละนิดจนเราหมดสิทธิ์เลือก สิ่งเดียวที่เราจะเลือกได้คือ ซื้อเนื้อจากแลปไหน #pirateketo #กูต้องรู้มั๊ย #ม้วนหางสิลูก #siamstr

2025-05-27 09:21:40“The future is there... staring back at us. Trying to make sense of the fiction we will have become.” — William Gibson.
This month is the 4th anniversary of kycnot.me. Thank you for being here.
Fifteen years ago, Satoshi Nakamoto introduced Bitcoin, a peer-to-peer electronic cash system: a decentralized currency free from government and institutional control. Nakamoto's whitepaper showed a vision for a financial system based on trustless transactions, secured by cryptography. Some time forward and KYC (Know Your Customer), AML (Anti-Money Laundering), and CTF (Counter-Terrorism Financing) regulations started to come into play.
What a paradox: to engage with a system designed for decentralization, privacy, and independence, we are forced to give away our personal details. Using Bitcoin in the economy requires revealing your identity, not just to the party you interact with, but also to third parties who must track and report the interaction. You are forced to give sensitive data to entities you don't, can't, and shouldn't trust. Information can never be kept 100% safe; there's always a risk. Information is power, who knows about you has control over you.
Information asymmetry creates imbalances of power. When entities have detailed knowledge about individuals, they can manipulate, influence, or exploit this information to their advantage. The accumulation of personal data by corporations and governments enables extensive surveillances.
Such practices, moreover, exclude individuals from traditional economic systems if their documentation doesn't meet arbitrary standards, reinforcing a dystopian divide. Small businesses are similarly burdened by the costs of implementing these regulations, hindering free market competition^1:
How will they keep this information safe? Why do they need my identity? Why do they force businesses to enforce such regulations? It's always for your safety, to protect you from the "bad". Your life is perpetually in danger: terrorists, money launderers, villains... so the government steps in to save us.
‟Hush now, baby, baby, don't you cry Mamma's gonna make all of your nightmares come true Mamma's gonna put all of her fears into you Mamma's gonna keep you right here, under her wing She won't let you fly, but she might let you sing Mamma's gonna keep baby cosy and warm” — Mother, Pink Floyd
We must resist any attack on our privacy and freedom. To do this, we must collaborate.
If you have a service, refuse to ask for KYC; find a way. Accept cryptocurrencies like Bitcoin and Monero. Commit to circular economies. Remove the need to go through the FIAT system. People need fiat money to use most services, but we can change that.
If you're a user, donate to and prefer using services that accept such currencies. Encourage your friends to accept cryptocurrencies as well. Boycott FIAT system to the greatest extent you possibly can.
This may sound utopian, but it can be achieved. This movement can't be stopped. Go kick the hornet's nest.
“We must defend our own privacy if we expect to have any. We must come together and create systems which allow anonymous transactions to take place. People have been defending their own privacy for centuries with whispers, darkness, envelopes, closed doors, secret handshakes, and couriers. The technologies of the past did not allow for strong privacy, but electronic technologies do.” — Eric Hughes, A Cypherpunk's Manifesto
The anniversary
Four years ago, I began exploring ways to use crypto without KYC. I bookmarked a few favorite services and thought sharing them to the world might be useful. That was the first version of kycnot.me — a simple list of about 15 services. Since then, I've added services, rewritten it three times, and improved it to what it is now.
kycnot.me has remained 100% independent and 100% open source^2 all these years. I've received offers to buy the site, all of which I have declined and will continue to decline. It has been DDoS attacked many times, but we made it through. I have also rewritten the whole site almost once per year (three times in four years).
The code and scoring algorithm are open source (contributions are welcome) and I can't arbitrarly change a service's score without adding or removing attributes, making any arbitrary alterations obvious if they were fake. You can even see the score summary for any service's score.
I'm a one-person team, dedicating my free time to this project. I hope to keep doing so for many more years. Again, thank you for being part of this.

2025-05-27 09:21:38Silent.link is an anonymous eSIM provider. They offer pay-as-you-go roaming in 160+ countries.
Pros
- Anonymous
- Private payment options
- High performance
- Global availability
Cons
- Need to select the right networks sometimes
- Latency
- Data and incoming SMS & call only

★★★★★
Service website
eSIMs replace traditional, physical SIM cards, if you have a fairly new phone, odds are it supports them. Since most people change their mobile carrier very rarely, the most common use case for these new eSIMs is their use in travel. Although their use as a piece of a larger OPSEC puzzle to improve privacy when using the internet from your phone is increasingly popular too.
Silent.link is not the only eSIM provider out there. Yet, they’re so unique that even Twitter’s (now X) founder Jack Dorsey recommends them.
Let’s start off with a quick explanation of how Silent.link works and what pay-as-you-go means. Most other eSIM providers will sell you packages of GBs with an expiration date. For instance imagine you’re visiting France then going to the UK after a few months. With other providers you might buy a 10GB in France package valid for 7 days, then after some months a 10GB in the UK package also valid for 7 days. You likely won’t use up the full package in either country and the remaining capacity will be voided as the package expires.
Silent.link’s pay-as-you-go is different. There are no geographic packages. There are no expiration dates. You simply have a balance denominated in USD and are charged as you use up the data according to the pricing of whichever local carrier you’re connecting via.
Preparing for the same trips from the example above you’d simply top-up your Silent.link balance with $10. Then you’d use Silent.link in France paying $1.33/GB, you’d only be charged for the exact amount used, then you’d go to the UK and pay $1.54/GB from the balance you had left over from France. It doesn’t matter how much time passes between the trips, because Silent.link balances don’t expire. If you have a balance left over you can use it on a future trip, or simply use it up in your home country.
Pros
Anonymity
Silent.link is anonymous. Most other eSIM providers require some form of identification. This can be a traditional, full KYC, procedure involving your ID or passport numbers or, as seemingly innocent, as verifying your phone number with your main carrier. Regardless, a link between the eSIM you bought online and your identity is established.
In some countries you’ll be able to pick up a traditional SIM (or the new eSIM) from a local carrier without undergoing this verification. This can still be a hassle though. You’ll need to look up the laws before travelling, you’ll need to find a local store selling them, you’ll need to decide how you’ll pay privately, etc. And that’s the best case, that’s assuming the country you want to get the SIM in allows you to buy one anonymously.
Private payment methods
Silent.link only accepts cryptocurrency and according to their stats, most payments are made with Bitcoin (either onchain or using the Lightning Network) or with Monero. As such paying anonymously is not a problem. The use a self-hosted instance of BTCPay Server to process payments and operate their own LN node. The entire checkout process can be completed over Tor.
Cons
Network selection
Although you can skip the hassle of buying a new eSIM every time you travel it’s a good idea to look up the pricing of different mobile networks in the country you’re going to. The differences can be trivial, but can also be 100x. If a specific mobile network offers a much better deal, you’ll probably want to dive into your phone’s settings to make sure it only connects to that network.
High prices for some regions
Second issue can be that, especially for poorer countries, Silent.link might not have the best prices. For instance if you travel to Angola you’ll end up paying $155.44/GB. But if you search around for other providers you’ll find eSIM that offer much lower prices for that same country.
Data & incoming SMS & calls only
These eSIMs are either data-only or only offer data and inbound sms and calls. You can’t use Silent.link eSIMs to send texts or make phone calls.
Latency
For most use-cases this shouldn’t matter, but the way roaming works is that when you’re abroad your data is first sent to your home country then sent out into the internet from there. For instance if you’re a Brit on holiday in Spain wherever you open up a website your phone communicates with the Spanish network who forwards the request to your home network in the UK and only there does the request start going towards the website you’re trying to load. The response takes the same path in reverse.
The home network for the Silent.link eSIMs is Poland. To take an extreme (antipodal) example, if you’re in Chile loading a Chilean website your request will go to Poland then back from Poland to the website’s server in Chile, then the response will go from Chile to Poland to you (in Chile). All those trips add latency. In our testing, done during the recent OrangeFren.com meetup in Istanbul, the difference was an additional 73ms. The bandwidth, however, was exceptional, easily surpassing 100 Mbps.
This latency issue isn’t unique to Silent.link, other eSIM providers usually suffer from it too, though their home network may be better suited for your latency needs. If you need the best latency we recommend a SIM from a local provider (or WiFi).
This proxy behaviour isn’t all negative however. It may potentially allow you to circumvent censorship or geoblocking if you’re trying to access resources available from Poland, but unavailable elsewhere.
Besides Istanbul one of the countries we also tested Silent.link in was Northern Cyprus. This territory is mostly unrecognized. It’s a country that, depending on who you ask, is or isn’t real. Despite this unresolved geopolitical status Silent.link performed without any issues.
Installation
If you decide to give Silent.link a try, you'll need to select if you want a data-only plan or a plan with inbound SMS & calling, once you complete the payment simply scan the QR code on the order confirmation page with your phone. Make sure to save the url of that order confirmation page somewhere! You will need it to top up your eSIM and check your remaining balance.
Getting in touch
The preferred way of contacting Silent.link's support is using the website's built-in chat function. Alternative methods include X (formerly Twitter), Matrix and email.
Their support is online from 09:00 - 21:00 UTC although even when testing outside of those hours we got a reply within a minute.
NOTE: These reviews are sponsored, yet the sponsorship does not influence the outcome of the evaluations. Sponsored reviews are independent from the kycnot.me list, being only part of the blog. The reviews have no impact on the scores of the listings or their continued presence on the list. Should any issues arise, I will not hesitate to remove any listing.

2024-12-03 09:00:46The History of Bananas as an Exportable Fruit and the Rise of Banana Republics
Bananas became a significant export in the late 19th century, fueled by advancements in transportation and refrigeration that allowed the fruit to travel long distances without spoilage. Originally native to Southeast Asia, bananas were introduced to the Americas by European colonists. By the late 1800s, companies like the United Fruit Company (later Chiquita) and Standard Fruit Company (now Dole) began cultivating bananas on a large scale in Central America and the Caribbean.
These corporations capitalized on the fruit’s appeal—bananas were cheap, nutritious, and easy to transport. The fruit quickly became a staple in Western markets, especially in the United States. However, the rapid expansion of banana exports came at a significant political and social cost to the countries where the fruit was grown.
To maintain control over banana production and maximize profits, these companies required vast amounts of arable land, labor, and favorable trade conditions. This often led them to form close relationships with local governments, many of which were authoritarian and corrupt. The companies influenced policies to secure land concessions, suppress labor rights, and maintain low taxes.
The term “banana republic” was coined by writer O. Henry in 1904 to describe countries—particularly in Central America—that became politically unstable due to their economic dependence on a single export crop, often controlled by foreign corporations.
The U.S. government frequently supported these regimes as part of its broader strategy during the Cold War to counter communist influence in the region. Washington feared that labor movements and demands for land reform, often supported by the peasantry and indigenous groups, could lead to the rise of socialist or communist governments. Consequently, the U.S. backed coups, such as the 1954 overthrow of Guatemala’s democratically elected President Jacobo Árbenz, who had threatened United Fruit’s interests by redistributing unused land.
These interventions created a legacy of exploitation, environmental degradation, and political instability in many banana-exporting countries. While bananas remain a global dietary staple, their history underscores the complex interplay of economics, politics, and imperialism.

Brazilian’s Central Bank Will Ban Monero and Algorithmic Stablecoins in the Country
Brazil proposes crypto regulations banning Monero and algorithmic stablecoins and enforcing strict compliance for exchanges.
KEY TAKEAWAYS
- The Central Bank of Brazil has proposed regulations prohibiting privacy-centric cryptocurrencies like Monero.
- The regulations categorize exchanges into intermediaries, custodians, and brokers, each with specific capital requirements and compliance standards.
- While the proposed rules apply to cryptocurrencies, certain digital assets like non-fungible tokens (NFTs) are still ‘deregulated’ in Brazil.
In a Notice of Participation announcement, the Brazilian Central Bank (BCB) outlines regulations for virtual asset service providers (VASPs) operating in the country.
In the document, the Brazilian regulator specifies that privacy-focused coins, such as Monero, must be excluded from all digital asset companies that intend to operate in Brazil.
Let’s unpack what effect these regulations will have.
Brazil’s Crackdown on Crypto Fraud
If the BCB’s current rule is approved, exchanges dealing with coins that provide anonymity must delist these currencies or prevent Brazilians from accessing and operating these assets.
The Central Bank argues that currencies like Monero make it difficult and even prevent the identification of users, thus creating problems in complying with international AML obligations and policies to prevent the financing of terrorism.
According to the Central Bank of Brazil, the bans aim to prevent criminals from using digital assets to launder money. In Brazil, organized criminal syndicates such as the Primeiro Comando da Capital (PCC) and Comando Vermelho have been increasingly using digital assets for money laundering and foreign remittances.
… restriction on the supply of virtual assets that contain characteristics of fragility, insecurity or risks that favor fraud or crime, such as virtual assets designed to favor money laundering and terrorist financing practices by facilitating anonymity or difficulty identification of the holder.
The Central Bank has identified that removing algorithmic stablecoins is essential to guarantee the safety of users’ funds and avoid events such as when Terraform Labs’ entire ecosystem collapsed, losing billions of investors’ dollars.
The Central Bank also wants to control all digital assets traded by companies in Brazil. According to the current proposal, the national regulator will have the power to ask platforms to remove certain listed assets if it considers that they do not meet local regulations.
However, the regulations will not include NFTs, real-world asset (RWA) tokens, RWA tokens classified as securities, and tokenized movable or real estate assets. These assets are still ‘deregulated’ in Brazil.
Monero: What Is It and Why Is Brazil Banning It?
Monero ($XMR) is a cryptocurrency that uses a protocol called CryptoNote. It launched in 2013 and ‘erases’ transaction data, preventing the sender and recipient addresses from being publicly known. The Monero network is based on a proof-of-work (PoW) consensus mechanism, which incentivizes miners to add blocks to the blockchain.
Like Brazil, other nations are banning Monero in search of regulatory compliance. Recently, Dubai’s new digital asset rules prohibited the issuance of activities related to anonymity-enhancing cryptocurrencies such as $XMR.
Furthermore, exchanges such as Binance have already announced they will delist Monero on their global platforms due to its anonymity features. Kraken did the same, removing Monero for their European-based users to comply with MiCA regulations.
Data from Chainalysis shows that Brazil is the seventh-largest Bitcoin market in the world.
In Latin America, Brazil is the largest market for digital assets. Globally, it leads in the innovation of RWA tokens, with several companies already trading this type of asset.
In Closing
Following other nations, Brazil’s regulatory proposals aim to combat illicit activities such as money laundering and terrorism financing.
Will the BCB’s move safeguard people’s digital assets while also stimulating growth and innovation in the crypto ecosystem? Only time will tell.

Jippi Launches Pokémon GO-Style AR Bitcoin Education Game at Vegas’s Bitcoin 2025Jippi, a mobile augmented reality (AR) game developer, will debut its Bitcoin education game at the Bitcoin Conference 2025, held at The Venetian Resort in Las Vegas from May 27-29. Inspired by Pokémon GO, the game blends location-based gameplay with financial literacy, aiming to engage over 30,000 attendees by making Bitcoin education fun and accessible.
Using the app, players can explore The Venetian’s grounds to hunt digital “Bitcoin Beasts,” answering Bitcoin-related trivia to capture them and earn 1000 satoshis (sats) per catch. The game is designed to deliver concise lessons on sound money principles, targeting younger audiences, with Jippi’s research showing 90% of Gen Z play mobile games. This approach aims to make learning about Bitcoin intuitive and engaging.
“We’re excited to turn Bitcoin education into an adventure,” said Oliver Porter, Jippi’s Founder and CEO. “Our game meets players where they are, making complex concepts approachable.”
Jippi partnered with six Bitcoin companies—Bitcoin Well, Beyond The Checkout, Bitcoin Trading Cards, Geyser, SHAmory, and 21M Communications—to sponsor unique Beasts. Each is tied to a specific location, offering tailored trivia that highlights the sponsor’s mission. For instance, Bitcoin Well’s Beast teaches wallet security, while SHAmory’s content suits all ages. “Jippi’s game is a fresh way to onboard new users,” said Adam O’Brien, CEO of Bitcoin Well.
The game stems from over a year of development, including university testing and on-site surveys. Jippi’s efforts earned it the top prize at PlebLab’s Top Builder competition in March 2025, a hackathon for Bitcoin startups, cementing its role in gamifying education.
With 30,000 attendees expected, the conference is an ideal stage for Jippi to showcase AR’s potential in Bitcoin adoption. The game promises to transform The Venetian into a dynamic learning hub, encouraging players to explore while grasping Bitcoin’s real-world applications. Jippi aims to expand the game post-conference, adding more educational content.

2025-05-27 09:21:37After almost 3 months of work, we've completed the redesign of kycnot.me. More modern and with many new features.
Privacy remains the foundation - everything still works with JavaScript disabled. If you enable JS, you will get some nice-to-have features like lazy loading and smoother page transitions, but nothing essential requires it.
User Accounts
We've introduced user accounts that require zero personal information:
- Secret user tokens - no email, no phone number, no personal data
- Randomly generated usernames for default privacy and fairness
- Karma system that rewards contributions and unlocks features: custom display names, profile pictures, and more.
Reviews and Community Discussions
On the previous sites, I was using third party open source tools for the comments and discussions. This time, I've built my own from scratch, fully integrated into the site, without JavaScript requirements.
Everyone can share their experiences and help others make informed decisions:
- Ratings: Comments can have a 1-5 star rating attached. You can have one rating per service and it will affect the overall user score.
- Discussions: These are normal comments, you can add them on any listed service.
Comment Moderation
I was strugling to keep up with moderation on the old site. For this, we've implemented an AI-powered moderation system that:
- Auto-approves legitimate comments instantly
- Flags suspicious content for human review
- Keeps discussions valuable by minimizing spam
The AI still can mark comments for human review, but most comments will get approved automatically by this system. The AI also makes summaries of the comments to help you understand the overall sentiment of the community.
Powerful Search & Filtering
Finding exactly what you need is now easier:
- Advanced filtering system with many parameters. You can even filter by attributes to pinpoint services with specific features.
The results are dynamic and shuffle services with identical scores for fairness.
See all listings
Listings are now added as 'Community Contributed' by default. This means that you can still find them in the search results, but they will be clearly marked as such.
Updated Scoring System
New dual-score approach provides more nuanced service evaluations:
- Privacy Score: Measures how well a service protects your personal information and data
-
Trust Score: Assesses reliability, security, and overall reputation
-
Combined into a weighted Overall Score for quick comparisons
- Completely transparent and open source calculation algorithm. No manual tweaking or hidden factors.
AI-Powered Terms of Service Analysis
Basically, a TLDR summary for Terms of Service:
- Automated system extracts the most important points from complex ToS documents
- Clear summaries
- Updated monthly to catch any changes
The ToS document is hashed and only will be updated if there are any changes.
Service Events and Timelines
Track the complete history of any service, on each service page you can see the timeline of events. There are two types of events:
- Automatic events: Created by the system whenever something about a service changes, like its description, supported currencies, attributes, verification status…
- Manual events: Added by admins when there’s important news, such as a service going offline, being hacked, acquired, shut down, or other major updates.
There is also a global timeline view available at /events
Notification System
Since we now have user accounts, we built a notifiaction system so you can stay informed about anything:
- Notifications for comment replies and status changes
- Watch any comment to get notified for new replies.
- Subscribe to services to monitor events and updates
- Notification customization.
Coming soon: Third-party privacy-preserving notifications integration with Telegram, Ntfy.sh, webhooks...

2024-11-17 17:33:55Let me tell you a beautiful story. Last night, during the speakers' dinner at Monerotopia, the waitress was collecting tiny tips in Mexican pesos. I asked her, "Do you really want to earn tips seriously?" I then showed her how to set up a Cake Wallet, and she started collecting tips in Monero, reaching 0.9 XMR. Of course, she wanted to cash out to fiat immediately, but it solved a real problem for her: making more money. That amount was something she would never have earned in a single workday. We kept talking, and I promised to give her Zoom workshops. What can I say? I love people, and that's why I'm a natural orange-piller.

2024-09-06 12:49:46Nostr: a quick introduction, attempt #2
Nostr doesn't subscribe to any ideals of "free speech" as these belong to the realm of politics and assume a big powerful government that enforces a common ruleupon everybody else.
Nostr instead is much simpler, it simply says that servers are private property and establishes a generalized framework for people to connect to all these servers, creating a true free market in the process. In other words, Nostr is the public road that each market participant can use to build their own store or visit others and use their services.
(Of course a road is never truly public, in normal cases it's ran by the government, in this case it relies upon the previous existence of the internet with all its quirks and chaos plus a hand of government control, but none of that matters for this explanation).
More concretely speaking, Nostr is just a set of definitions of the formats of the data that can be passed between participants and their expected order, i.e. messages between clients (i.e. the program that runs on a user computer) and relays (i.e. the program that runs on a publicly accessible computer, a "server", generally with a domain-name associated) over a type of TCP connection (WebSocket) with cryptographic signatures. This is what is called a "protocol" in this context, and upon that simple base multiple kinds of sub-protocols can be added, like a protocol for "public-square style microblogging", "semi-closed group chat" or, I don't know, "recipe sharing and feedback".

2025-02-09 16:50:04There has been a good bit of discussion on Nostr over the past few days about the merits of zaps as a method of engaging with notes, so after writing a rather lengthy article on the pros of a strategic Bitcoin reserve, I wanted to take some time to chime in on the much more fun topic of digital engagement.
Let's begin by defining a couple of things:
Nostr is a decentralized, censorship-resistance protocol whose current biggest use case is social media (think Twitter/X). Instead of relying on company servers, it relies on relays that anyone can spin up and own their own content. Its use cases are much bigger, though, and this article is hosted on my own relay, using my own Nostr relay as an example.
Zap is a tip or donation denominated in sats (small units of Bitcoin) sent from one user to another. This is generally done directly over the Lightning Network but is increasingly using Cashu tokens. For the sake of this discussion, how you transmit/receive zaps will be irrelevant, so don't worry if you don't know what Lightning or Cashu are.
If we look at how users engage with posts and follows/followers on platforms like Twitter, Facebook, etc., it becomes evident that traditional social media thrives on engagement farming. The more outrageous a post, the more likely it will get a reaction. We see a version of this on more visual social platforms like YouTube and TikTok that use carefully crafted thumbnail images to grab the user's attention to click the video. If you'd like to dive deep into the psychology and science behind social media engagement, let me know, and I'd be happy to follow up with another article.
In this user engagement model, a user is given the option to comment or like the original post, or share it among their followers to increase its signal. They receive no value from engaging with the content aside from the dopamine hit of the original experience or having their comment liked back by whatever influencer they provide value to. Ad revenue flows to the content creator. Clout flows to the content creator. Sales revenue from merch and content placement flows to the content creator. We call this a linear economy -- the idea that resources get created, used up, then thrown away. Users create content and farm as much engagement as possible, then the content is forgotten within a few hours as they move on to the next piece of content to be farmed.
What if there were a simple way to give value back to those who engage with your content? By implementing some value-for-value model -- a circular economy. Enter zaps.
Unlike traditional social media platforms, Nostr does not actively use algorithms to determine what content is popular, nor does it push content created for active user engagement to the top of a user's timeline. Yes, there are "trending" and "most zapped" timelines that users can choose to use as their default, but these use relatively straightforward engagement metrics to rank posts for these timelines.
That is not to say that we may not see clients actively seeking to refine timeline algorithms for specific metrics. Still, the beauty of having an open protocol with media that is controlled solely by its users is that users who begin to see their timeline gamed towards specific algorithms can choose to move to another client, and for those who are more tech-savvy, they can opt to run their own relays or create their own clients with personalized algorithms and web of trust scoring systems.
Zaps enable the means to create a new type of social media economy in which creators can earn for creating content and users can earn by actively engaging with it. Like and reposting content is relatively frictionless and costs nothing but a simple button tap. Zaps provide active engagement because they signal to your followers and those of the content creator that this post has genuine value, quite literally in the form of money—sats.
I have seen some comments on Nostr claiming that removing likes and reactions is for wealthy people who can afford to send zaps and that the majority of people in the US and around the world do not have the time or money to zap because they have better things to spend their money like feeding their families and paying their bills. While at face value, these may seem like valid arguments, they, unfortunately, represent the brainwashed, defeatist attitude that our current economic (and, by extension, social media) systems aim to instill in all of us to continue extracting value from our lives.
Imagine now, if those people dedicating their own time (time = money) to mine pity points on social media would instead spend that time with genuine value creation by posting content that is meaningful to cultural discussions. Imagine if, instead of complaining that their posts get no zaps and going on a tirade about how much of a victim they are, they would empower themselves to take control of their content and give value back to the world; where would that leave us? How much value could be created on a nascent platform such as Nostr, and how quickly could it overtake other platforms?
Other users argue about user experience and that additional friction (i.e., zaps) leads to lower engagement, as proven by decades of studies on user interaction. While the added friction may turn some users away, does that necessarily provide less value? I argue quite the opposite. You haven't made a few sats from zaps with your content? Can't afford to send some sats to a wallet for zapping? How about using the most excellent available resource and spending 10 seconds of your time to leave a comment? Likes and reactions are valueless transactions. Social media's real value derives from providing monetary compensation and actively engaging in a conversation with posts you find interesting or thought-provoking. Remember when humans thrived on conversation and discussion for entertainment instead of simply being an onlooker of someone else's life?
If you've made it this far, my only request is this: try only zapping and commenting as a method of engagement for two weeks. Sure, you may end up liking a post here and there, but be more mindful of how you interact with the world and break yourself from blind instinct. You'll thank me later.

2025-02-03 22:25:35Last week, in a bid to understand the LLM hype, I decided to write a trivial nostr-related program in rust via a combination of codebuff (yes, that is a referral link, pls click), aider, and goose.
The result of the experiment was inconclusive, but as a side effect it produced a great case study in converting a NINO into a Real Nostr App.
Introducing Roz
Roz, a friendly notary for nostr events.
To use it, simply publish an event to
relay.damus.io
ornos.lol
, and roz will make note of it. To find out when roz first saw a given event, just ask:curl https://roz.coracle.social/notary/cb429632ae22557d677a11149b2d0ccd72a1cf66ac55da30e3534ed1a492765d
This will return a JSON payload with a
seen
key indicating when roz first saw the event. How (and whether) you use this is up to you!De-NINO-fying roz
Roz is just a proof of concept, so don't rely on it being there forever. And anyway, roz is a NINO, since it provides value to nostr (potentially), but doesn't really do things in a nostr-native way. It also hard-codes its relays, and certainly doesn't use the outbox model or sign events. But that's ok, it's a proof of concept.
A much better way to do this would be to modify roz to properly leverage nostr's capabilities, namely:
- Use nostr-native data formats (i.e., draft a new kind)
- Use relays instead of proprietary servers for data storage
- Leverage nostr identities and signatures to decouple trust from storage, and allow trusted attestations to be discovered
Luckily, this is not hard at all. In fact, I've gone ahead and drafted a PR to the NIPs repo that adds timestamp annotations to NIP 03, as an alternative to OpenTimestamps. The trade-off is that while user attestations are far less reliable than OTS proofs, they're much easier to verify, and can reach a pretty high level of reliability by combining multiple attestation sources with other forms of reputation.
In other words, instead of going nuclear and embedding your attestations into The Time Chain, you can simply ask 5-10 relays or people you trust for their attestations for a given event.
This PR isn't terribly important on its own, but it does remove one small barrier between us and trusted key rotation events (or other types of event that require establishing a verifiable chain of causality).

2025-05-26 06:12:06น้ำมันอัลมอนด์ เป็นหนึ่งในน้ำมันพืชที่ได้รับความนิยมอย่างเงียบ ๆ ทั้งในวงการสุขภาพ ความงาม และอาหาร โดยเฉพาะในกลุ่มผู้รักสุขภาพที่มองหาทางเลือกของไขมันดีจากธรรมชาติ แม้อาจไม่โด่งดังเท่าน้ำมันมะกอกหรือน้ำมันอะโวคาโด แต่คุณสมบัติของมันกลับน่าสนใจไม่น้อย และมีประวัติการใช้งานมายาวนานตั้งแต่ยุคอารยธรรมเมโสโปเตเมียจนถึงอาณาจักรเปอร์เซีย ซึ่งมีการใช้อัลมอนด์ทั้งในรูปของอาหารและยาท้องถิ่น น้ำมันอัลมอนด์ที่นำมาใช้ในปัจจุบัน มักได้จาก “อัลมอนด์หวาน” (Sweet almond – Prunus dulcis var. dulcis) ซึ่งต่างจากอัลมอนด์ขม (Prunus dulcis var. amara) ที่มีสารอะมิกดาลิน (amygdalin) ซึ่งสามารถแตกตัวเป็นไซยาไนด์ได้ จึงไม่เหมาะกับการบริโภคโดยตรง
วิธีการผลิตน้ำมันอัลมอนด์ในรูปแบบที่พบมากในท้องตลาด มีอยู่ 2 แบบหลัก คือ การสกัดเย็น (Cold-pressed) ซึ่งนิยมในกลุ่มสุขภาพเพราะไม่ผ่านความร้อนและไม่ใช้สารเคมี ทำให้คงสารอาหารและพฤกษเคมีธรรมชาติไว้ได้ดี กับอีกแบบคือการสกัดด้วยตัวทำละลาย (เช่น hexane) ซึ่งทำให้ได้น้ำมันปริมาณมากแต่ต้องผ่านการฟอกและกลั่น ทำให้สูญเสียกลิ่น สี และสารบางชนิดในธรรมชาติไป น้ำมันที่ได้จะเป็นของเหลวใส สีเหลืองทองอ่อน มีกลิ่นหอมอ่อน ๆ คล้ายน้ำมันมะกอก
ในแง่ขององค์ประกอบไขมัน น้ำมันอัลมอนด์มีกรดไขมันไม่อิ่มตัวสูง โดยเฉพาะกรดโอเลอิก (oleic acid – omega-9) ประมาณ 62–70% และกรดลิโนเลอิก (linoleic acid – omega-6) ประมาณ 20–30% ส่วนกรดไขมันอิ่มตัวมีเพียงเล็กน้อยราว 6–8% เท่านั้น ทำให้จัดอยู่ในกลุ่มน้ำมันที่มีไขมันดีสูง คล้ายคลึงกับน้ำมันมะกอก นอกจากนี้ยังมีวิตามินอีธรรมชาติ (tocopherol) อยู่ราว 39.2–46.4 มิลลิกรัมต่อ 100 กรัม และ phytosterols ราว 280–320 มิลลิกรัมต่อ 100 กรัม ซึ่งล้วนเป็นสารต้านอนุมูลอิสระที่มีบทบาทในการปกป้องเซลล์จากการเสื่อมและการอักเสบ
กรดลิโนเลอิก (LA) เองในธรรมชาติไม่ใช่ตัวร้ายนะจ๊ะ ร่างกายต้องใช้มันเล็กน้อยเพื่อเป็นโครงสร้างของเซลล์ และสร้างสาร prostaglandin บางชนิด จะเห็นว่าน้ำมันอัลมอนด์อยู่กลาง ๆ ระหว่างน้ำมันพืชสายฟังดูดีอย่างคาโนลา กับน้ำมันมะกอก ซึ่งแปลว่า ไม่ได้แย่มาก แต่ก็ไม่จัดว่าต่ำ เฮียจะพิจารณาให้เหมาะกับเป้าหมายสุขภาพของตัวเองได้เลย สาย anti-inflammatory, animal-based, ketogenic หรือ low-PUFA lifestyle ก็อาจจะจำกัด ปริมาณ LA ให้ไม่เกิน 2–4% ของพลังงานรวมต่อวัน (แนวทางที่ Dr. Cate Shanahan และ Dr. Chris Knobbe แนะนำ)
ถึงอย่างนั้น หากมองในแง่ของ “พฤกษเคมี” ที่จะอวดอ้างสรรพคุณทางสุขภาพ ต้องยอมรับว่าน้ำมันอัลมอนด์ยังไม่ใช่น้ำมันที่เด่นที่สุด เพราะปริมาณสาร polyphenols และ flavonoids นั้นน้อยกว่าน้ำมันจากผลไม้ เช่น น้ำมันมะกอกแบบ extra virgin หรือน้ำมันงาดำแบบสกัดเย็น กล่าวคือ แม้จะพอมีสารที่ดี แต่ปริมาณยังไม่มากพอให้เกิดผลทางชีวภาพอย่างชัดเจนจากการบริโภคตามปกติ ดังนั้นในด้านการตลาด แม้มีการกล่าวอ้างว่าน้ำมันอัลมอนด์ดีต่อหัวใจและต้านอนุมูลอิสระ ควรพิจารณาอย่างระมัดระวัง โดยเฉพาะในผลิตภัณฑ์ที่ไม่ได้แสดงวิธีการผลิตและปริมาณของสารออกฤทธิ์อย่างชัดเจน
สำหรับการใช้งานในชีวิตประจำวัน น้ำมันอัลมอนด์มีจุดเกิดควันอยู่ที่ประมาณ 216–221°C ทำให้สามารถใช้ประกอบอาหารแบบผัดหรืออบได้ แต่ไม่เหมาะกับการทอดแบบ deep fry เพราะอาจเกิดออกซิเดชันเร็วจากกรดไขมันไม่อิ่มตัวสูง ส่วนในวงการเครื่องสำอางและสกินแคร์ น้ำมันอัลมอนด์ถือเป็นน้ำมันยอดนิยมที่ใช้เป็นเบสน้ำมันสำหรับนวดตัว หรือผสมในโลชั่น เพราะซึมง่าย ไม่เหนียวเหนอะหนะ และอ่อนโยนต่อผิว โดยเฉพาะในเด็กเล็กก็ยังใช้ได้ดี
ในประเทศไทย น้ำมันอัลมอนด์ที่จำหน่ายมีทั้งผลิตภัณฑ์นำเข้าในรูปแบบ refined หรือ cold-pressed โดยมีทั้งแบบใช้ปรุงอาหาร และแบบสำหรับใช้ภายนอก เฮียแนะนำว่า ถ้าจะเลือกใช้กินควรเลือกให้ตรงความต้องการจริงๆ ถ้าเป็นแบบ cold-pressed ที่ระบุแหล่งผลิตชัดเจน เพื่อความมั่นใจในกระบวนการ และควรเก็บในขวดทึบแสง หลีกเลี่ยงความชื้นและแสงแดด เพราะน้ำมันประเภทนี้เหม็นหืนได้ง่ายเมื่อสัมผัสอากาศและแสงนาน ๆ
แม้น้ำมันอัลมอนด์จะไม่ได้มีพลังวิเศษแบบที่ใคร ๆ โปรยคำโฆษณาไว้ แต่ถ้าเข้าใจธรรมชาติของมันอย่างถ่องแท้ เฮียว่าก็ถือเป็นไขมันดีอีกตัวที่น่ามีไว้ในครัว โดยเฉพาะในเมนูอบ เบเกอรี่ หรืออาหารที่ต้องการรสชาติกลมกล่อมหอมมันแบบนุ่มละมุนที่มาพร้อมวิตามินอีจากธรรมชาติ โดยไม่ต้องง้อสารกันหืนเทียมจากโรงงาน #pirateketo #กูต้องรู้มั๊ย #ม้วนหางสิลูก #siamstr

2024-08-16 01:59:24Traditionally, miso making takes place during the cold winter. Miso is fermented during the warm season and start using after it gets cooler in the fall. However, I did make during the summer and there was no problem.
For 29oz miso
Ingredients: * Chickpeas 0.5lbs(227g) * Dried Koji 0.5lbs(227g) *not raw(active) koji * Natural salts 103g * Chickpeas : Koji: Salts = 1: 1: 0.45 (salts 12.5%)
I find chickpeas easier to handle than soy beans. For soy beans,
- Soy beans 230g (soak at least 18 hours)
- Dried Koji 340g
- Natural salts 30g(Salts 12.5%)
You also need :
Container for fermentation -32 oz glass jar (no metal lid) or strong plastic container or bag that can be sealed. * large mixing bowl
small bowl
* pressure cooker or large pot * food processor or blender or masher (I use the bottom of small glass jar sanitized with hotwater) * parchment paper or plastic wrap to cover the surface- Wash chickpeas and soak over night
- Cook chickpeas until it can be crashed with your thumb and pinky finger with a pressure cooker or a pot (this may take hours with a pot) Move a part of cooked liquid from the pot to a small bowl and drain the rest. Wait until chickpeas can be handled with hand.
- Mash chickpeas into paste
- Sanitize the 32oz jar with hot water or sanitizer of your choice
- Mixed dried koji with salts with hand
- Add koji and salts to the chickpea paste. Mix with hand well. Add a little bit of the liquid you put aside earlier if the paste is too dry (do not add too much).
- When mixed well, make balls with the paste using hands.
- Throw one of the balls into the jar and push onto the jar with your fist. Repeat this process. (you don't have to punch here. Just push. This process is to transfer the miso paste into the jar without air. The exposure to air will lead to mold. Make sure not to have a space.)
- After throwing all balls into the jar and place tightly without air, seal the surface with a piece of parchment paper or plastic wrap.
- Close the lid.
- Place the jar in a cool and dark place (room temperature). Leave 6 months to 2 years. After the half of the duration, you may pull out of paste and place the bottom half onto the upper half so that the miso will be evenly fermented. This process can be skipped. Check once in a couple of months if there is mold.
- If mold appears on the surface, just scrape it off.

2025-01-29 05:55:02The land that belongs to the indigenous peoples of Russia has been seized by a gang of killers who have unleashed a war of extermination. They wipe out anyone who refuses to conform to their rules. Those who disagree and stay behind are tortured and killed in prisons and labor camps. Those who flee lose their homeland, dissolve into foreign cultures, and fade away. And those who stand up to protect their people are attacked by the misled and deceived. The deceived die for the unchecked greed of a single dictator—thousands from both sides, people who just wanted to live, raise their kids, and build a future.
Now, they are forced to make an impossible choice: abandon their homeland or die. Some perish on the battlefield, others lose themselves in exile, stripped of their identity, scattered in a world that isn’t theirs.
There’s been endless debate about how to fix this, how to clear the field of the weeds that choke out every new sprout, every attempt at change. But the real problem? We can’t play by their rules. We can’t speak their language or use their weapons. We stand for humanity, and no matter how righteous our cause, we will not multiply suffering. Victory doesn’t come from matching the enemy—it comes from staying ahead, from using tools they haven’t mastered yet. That’s how wars are won.
Our only resource is the will of the people to rewrite the order of things. Historian Timothy Snyder once said that a nation cannot exist without a city. A city is where the most active part of a nation thrives. But the cities are occupied. The streets are watched. Gatherings are impossible. They control the money. They control the mail. They control the media. And any dissent is crushed before it can take root.
So I started asking myself: How do we stop this fragmentation? How do we create a space where people can rebuild their connections when they’re ready? How do we build a self-sustaining network, where everyone contributes and benefits proportionally, while keeping their freedom to leave intact? And more importantly—how do we make it spread, even in occupied territory?
In 2009, something historic happened: the internet got its own money. Thanks to Satoshi Nakamoto, the world took a massive leap forward. Bitcoin and decentralized ledgers shattered the idea that money must be controlled by the state. Now, to move or store value, all you need is an address and a key. A tiny string of text, easy to carry, impossible to seize.
That was the year money broke free. The state lost its grip. Its biggest weapon—physical currency—became irrelevant. Money became purely digital.
The internet was already a sanctuary for information, a place where people could connect and organize. But with Bitcoin, it evolved. Now, value itself could flow freely, beyond the reach of authorities.
Think about it: when seedlings are grown in controlled environments before being planted outside, they get stronger, survive longer, and bear fruit faster. That’s how we handle crops in harsh climates—nurture them until they’re ready for the wild.
Now, picture the internet as that controlled environment for ideas. Bitcoin? It’s the fertile soil that lets them grow. A testing ground for new models of interaction, where concepts can take root before they move into the real world. If nation-states are a battlefield, locked in a brutal war for territory, the internet is boundless. It can absorb any number of ideas, any number of people, and it doesn’t run out of space.
But for this ecosystem to thrive, people need safe ways to communicate, to share ideas, to build something real—without surveillance, without censorship, without the constant fear of being erased.
This is where Nostr comes in.
Nostr—"Notes and Other Stuff Transmitted by Relays"—is more than just a messaging protocol. It’s a new kind of city. One that no dictator can seize, no corporation can own, no government can shut down.
It’s built on decentralization, encryption, and individual control. Messages don’t pass through central servers—they are relayed through independent nodes, and users choose which ones to trust. There’s no master switch to shut it all down. Every person owns their identity, their data, their connections. And no one—no state, no tech giant, no algorithm—can silence them.
In a world where cities fall and governments fail, Nostr is a city that cannot be occupied. A place for ideas, for networks, for freedom. A city that grows stronger the more people build within it.

2025-05-23 09:33:55The article below brings together some of the Q&A from our recent AMA on Reddit. Thanks so much for sending in your questions—we love chatting with you and being part of this awesome community!
Meepo Hardfork Features
What does Meepo bring to CKB, in simple terms?
Imagine upgrading from wooden blocks to LEGO bricks. That’s what the
spawn
syscall in Meepo does for CKB smart contracts, enabling script interoperability.Spawn and a series of related syscalls are introduced as a major upgrade to CKB-VM, enabling interoperability, modularity, and better developer experience, by letting scripts call other scripts, like modular apps in an operating system.
Key features of the upgraded VM?
The upgraded CKB-VM Meepo version unlocks true decoupling and reuse of CKB scripts, enhancing modularity and reusability in smart contract development.
For instance, before Meepo, if developers wanted to build a new time lock in CKB, they had to bundle all necessary functionalities—like signature algorithms—directly into a single lock or type script. This often led to bloated scripts where most of the code was unrelated to the developer's original design goal (time lock). With the spawn syscall, scripts can now delegate tasks—such as signature checks—to other on-chain scripts. As new algorithms emerge, the time lock can adopt them without being redeployed—just by calling updated signature scripts, as long as a shared protocol is followed.
This separation allows developers to: - Focus solely on their core logic. - Reuse independently deployed signature verification scripts. - Upgrade cryptographic components without modifying the original script. - Embrace a more OS-like model where smart contracts can call each other to perform specialized tasks.
By enabling true decoupling and reuse, the spawn syscall makes CKB scripts significantly more composable, maintainable, and adaptable.
Besides Spawn, other improvements in Meepo include:
- Block Extension Fields: Enables reading extension fields in blocks, opening new possibilities like community voting on hardforks (as this ckb-zero-lock prototype). More use cases are expected.
- CKB-VM Optimization: Reduces cycle consumption for common compiler-generated code, making scripts faster and more efficient.
A practical example: IPC on Spawn
Here's an example building an entire Inter-Process Communication (IPC) layer on top of spawn syscalls: - GitHub Repo - Blog post: Transforming IPC in CKB On-Chain Script: Spawn and the Custom Library for Simplified Communication
What does “every wallet will become a CKB wallet because of ckb-auth” mean?
Current CKB-VM already comes with the power to build omnilock / ckb-auth, spawn just makes them easier to reuse in new scripts through decoupling and improved modularity.
Upgrade Compatibility Concerns
Will Meepo require a new address format?
No. Meepo does not introduce breaking changes like address format switching. The only required upgrade is support for a new hash type (
data2
). We aim to keep upgrades smooth and backwards-compatible wherever possible.RISC-V & CKB’s Long-Term Design Philosophy
Ethereum is exploring RISC-V—CKB has been doing this for years. What’s your take?
The discussion about RISC-V in Ethereum, is partly about the ease of building zk solutions on Ethereum. And it's easy to mix two different use cases of RISC-V in zk:
- Use RISC-V as the language to write programs running in a zk engine. In this case, we use zero knowledge algorithms to build a RISC-VM and prove programs running inside these RISC-V VMs.
- Use RISC-V as the underlying engine to run cryptographic algorithms, we then compile the verifier / prover code of zero knowledge algorithm into RISC-V, then we run those verifiers / provers inside RISC-V. Essentially, we run the verifying / proving algorithms of zero knowledge algorithms in RISC-V, the programs running inside ZK VMs can be written in other languages suiting the zk algorithms.
When most people talk about RISC-V in zk, they mean the first point above. As a result, we see a lot of arguments debating if RISC-V fits in zk circuits. I couldn't get a direct confirmation from Vitalik, but based on what I read, when Vitalik proposes the idea of RISC-V in Ethereum, he's at least partly thinking about the second point here. The original idea is to introduce RISC-V in Ethereum, so we can just compile zk verifiers / provers into RISC-V code, so there is no need to introduce any more precompiles so as to support different zk algorithms in Ethereum. This is indeed a rare taken path, but I believe it is a right path, it is also the path CKB chose 7 years ago for the initial design of CKB-VM.
CKB believes that a precompile-free approach is the only viable path if we’re serious about building a blockchain that can last for decades—or even centuries. Cryptographic algorithms evolve quickly; new ones emerge every few years, making it unsustainable for blockchains to keep adding them as precompiles. In contrast, hardware evolves more slowly and lives longer.
By choosing RISC-V, we’ve committed to a model that can better adapt to future cryptographic developments. CKB may be on an uncommon path, but I believe it's the right one—and it's encouraging to see Ethereum now moving in a similar direction. Hopefully, more will follow.
CKB already stands out as the only blockchain VM built on RISC-V and entirely free from cryptographic precompiles. Meepo, with its spawn syscall, builds on this foundation—pushing for even greater modularity and reuse. We're also closely watching progress in the RISC-V ecosystem, with the goal of integrating hardware advances into CKB-VM, making it even more future-proof and a state-of-the-art execution environment for blockchain applications.
Will CKB run directly on RISC-V chips? What are the implications?
The "CKB on RISC-V"comes in several stages:
- For now, CKB-VM can already be compiled into RISC-V architecture and run on a RISC-V CPU (e.g. StarFive board), though optimized native implementations are still in development.
- That said, one key issue in the previous stage was that CKB-VM lacks a high-performance, assembly based VM on RISC-V architecture. Ironically, despite CKB-VM being based on RISC-V, we ended up running a Rust-based VM interpreter on RISC-V CPUs—which is far from ideal.
The root of the problem is that RISC-V CPUs come in many configurations, each supporting a different set of extensions. Porting CKB-VM to run natively on real RISC-V chips isn’t trivial—some extensions used by CKB-VM might not be available on the target hardware. With enough time and effort, a performant native implementation could be built, but it’s a non-trivial challenge that still needs significant work.
How do you see the RISC-V narrative expanding?
We are delighted to see the growing recognition of RISC-V in the blockchain space. For CKB, we firmly believe RISC-V is the best choice. Consensus is costly, so only essential data should be on-chain, with the chain serving as a universal verification layer—this is CKBʼs philosophy, and we have consistently designed and developed in this direction.
CKB Roadmap & Ecosystem Growth
Any plan to boost the usage of the CKB network in the next 6 - 24 months?
Growth starts with better developer experience. Spawn in Meepo significantly lowers the barrier to building complex apps. With better tools and documentation, more devs can experiment on CKB, leading to better apps and more users.
What would you focus on if the secondary issuance budget was huge?
If funding were abundant, we'd expand the Spark Program, support more grassroots projects, and even evolve toward a fully decentralized DAO structure—aligning with our long-term vision of a permissionless, community-owned network.
What’s next for Nervos after Meepo?
We're exploring new RISC-V extensions like CFI, which could boost script security and defend against ROP attacks. Still early-stage, but promising. Check out this: Against ROP Attacks: A Blockchain Architect’s Take on VM-Level Security.

2025-05-26 01:12:10ปลายศตวรรษที่ 20 โลกเรายังหมุนไปตามจังหวะของธรรมชาติ ท่ามกลางความเปลี่ยนแปลงทั้งการเมือง สังคม และเทคโนโลยี มีชายคนหนึ่งจากดินแดนกังหันลมชื่อว่า Willem van Eelen เขาไม่ใช่คนธรรมดา หากแต่เป็นนักคิดนักฝันที่เห็นภาพอนาคตอาหารแตกต่างจากคนทั่วไป เขาเติบโตขึ้นในช่วงเวลาที่โลกยังไม่ตระหนักถึงภาระหนักหน่วงของการเลี้ยงสัตว์ในระบบอุตสาหกรรมอย่างแท้จริง ในขณะที่คนส่วนใหญ่ยังเลือกทานเนื้อเหมือนเคย Willem กลับตั้งคำถามลึก ๆ ว่า “ทำไมเราต้องฆ่าสัตว์เพื่อจะได้เนื้อกินในเมื่อเราน่าจะสร้างเนื้อจากเซลล์โดยตรงได้?” คำถามนั้นกลายเป็นเมล็ดพันธุ์แห่งความหวังและการเปลี่ยนแปลงที่รอวันเติบโตในใจเขาอย่างเงียบ ๆ
Willem van Eelen เป็นอดีตทหารผ่านศึกสงครามโลกครั้งที่สอง เขาเคยถูกจับเป็นเชลยในช่วงเวลาที่โหดร้ายที่สุดของชีวิต เขาได้เห็นการฆ่าสัตว์อย่างโหดเหี้ยมและได้รับรู้ถึงความเจ็บปวดของสิ่งมีชีวิตเหล่านั้นอย่างลึกซึ้ง ความทรงจำและความเห็นใจนั้นกลายเป็นแรงผลักดันให้เขามุ่งมั่นพัฒนาแนวคิดที่จะหลีกเลี่ยงความเจ็บปวดและการทำลายล้างในวงจรของอาหารแบบเดิม ๆ ในยุคที่คำว่า “อาหารทางเลือก” ยังแทบไม่มีใครพูดถึง
ในยุคนั้น เทคโนโลยีชีวภาพยังอยู่ในช่วงเริ่มต้น เซลล์ต้นกำเนิดยังเป็นเรื่องลึกลับและต้องใช้เครื่องมือทางวิทยาศาสตร์ระดับสูงมากมาย Willem ลงมือศึกษาอย่างจริงจังถึงวิธีเพาะเลี้ยงเซลล์สัตว์ในห้องแล็บ เพื่อผลิตเนื้อโดยไม่ต้องฆ่าสัตว์ ความท้าทายสำคัญคือเขาต้องค้นหาวิธีให้เซลล์เนื้อเติบโตจนเป็นก้อนเนื้อที่นุ่มและมีโครงสร้างเหมือนเนื้อจริง ซึ่งในตอนนั้นยังไม่มีคำตอบแน่ชัดว่าเป็นไปได้จริงหรือไม่
ในปี 1999 Willem van Eelen ได้จดสิทธิบัตรเทคโนโลยี “เนื้อเพาะเลี้ยงเซลล์” หรือ Cultured Meat ไว้กับสำนักงานสิทธิบัตรของเนเธอร์แลนด์ สิทธิบัตรฉบับนี้กลายเป็นจุดเริ่มต้นที่สำคัญของวงการอาหารแห่งอนาคต แม้ว่าในเวลานั้นไอเดียของเขายังถูกมองด้วยความสงสัย หลายคนมองว่าเหมือนนิยายวิทยาศาสตร์เกินจริง และการผลิตเนื้อในห้องแล็บเป็นเรื่องไกลตัว
Willem ไม่ได้เดินทางนี้คนเดียว เขาทำงานร่วมกับนักชีววิทยา นักเทคโนโลยีชีวภาพ และนักสิ่งแวดล้อมหลายคนในยุโรป เขาตั้งกลุ่มผู้สนใจและเครือข่ายนักวิจัยเพื่อขยายงานและแบ่งปันความรู้ นอกจากนี้ มหาวิทยาลัย Maastricht ในเนเธอร์แลนด์ ยังเป็นฐานวิจัยหลักที่สนับสนุนงานของเขาในช่วงแรก ๆ แม้จะยังขาดแคลนทุนสนับสนุนจากภาครัฐและเอกชนก็ตาม
หนึ่งในปัญหาใหญ่ของการเพาะเลี้ยงเซลล์เนื้อในยุคนั้นคือการหาอาหารสำหรับเซลล์ หรือที่เรียกว่า Growth Medium โดยส่วนใหญ่ต้องพึ่งพาเซรุ่มจากเลือดวัว (Fetal Bovine Serum) ซึ่งมีราคาแพงและขัดแย้งกับหลักจริยธรรมของการลดการเบียดเบียนสัตว์เอง ความยากลำบากนี้ทำให้การพัฒนาเทคโนโลยีนี้เดินหน้าอย่างช้า ๆ
Willem ต้องพึ่งพิงทุนส่วนตัวและเงินบริจาคจากองค์กรสิ่งแวดล้อมและกลุ่มเคลื่อนไหวเพื่อสิทธิสัตว์ที่เห็นด้วยกับแนวคิดของเขา ถึงแม้ว่าจะไม่มีการสนับสนุนอย่างเป็นทางการจากรัฐบาลและภาคธุรกิจในช่วงแรก แต่ความมุ่งมั่นของเขาก็ไม่เคยจางหาย
ประวัติศาสตร์อาหารจึงมีบทเล็ก ๆ ที่บันทึกว่า Willem van Eelen เป็นนักฝันผู้ปลูกเมล็ดพันธุ์ของเนื้อเพาะเลี้ยงไว้ในดินแดนที่ยังไม่พร้อม แต่เมล็ดพันธุ์นั้นกลับเติบโตขึ้นเรื่อย ๆ จนกลายเป็นรากฐานของบริษัทและเทคโนโลยีในยุคปัจจุบันที่พยายามสร้างเนื้อที่ไม่ต้องฆ่าสัตว์แต่ยังคงรสสัมผัสและคุณค่าทางอาหาร
ปัจจุบัน เราเห็นบริษัทชื่อดังมากมายจากทั่วโลกล้วนแต่ก้าวตามรอยแนวคิดของ Willem โดยใช้เทคโนโลยีเพาะเลี้ยงเซลล์เนื้อที่พัฒนาขึ้นจนใกล้ความเป็นจริงมากขึ้นทั้งหมดนี้เกิดขึ้นจากแรงบันดาลใจและการทดลองของชายผู้ไม่ยอมแพ้ต่อความท้าทาย แม้จะต้องเผชิญกับข้อจำกัดทางเทคนิค ต้นทุนสูง และความไม่เชื่อมั่นจากสังคม
นี่ไม่ใช่แค่เรื่องเทคโนโลยีอาหาร แต่มันคือเรื่องของหัวใจที่ตั้งคำถามถึงความยั่งยืนและศีลธรรมในการบริโภคอาหารของมนุษย์ที่เปลี่ยนแปลงได้
คำว่า “เนื้อที่ไม่ต้องฆ่าสัตว์” ที่เรากล่าวถึงกันทุกวันนี้คือมรดกจากความฝันและความพยายามของ Willem van Eelen ที่เริ่มต้นมากว่าหนึ่งทศวรรษก่อนยุคสมัยจะพร้อมรับ
This is just a beginning ครับ #pirateketo #กูต้องรู้มั๊ย #ม้วนหางสิลูก #siamstr

2025-05-27 08:23:58Understanding or grasping Nostr can be deceptively difficult. At the very least it is non-trivial. At first glance, looking at NIP-01, the protocol is rather straight forward. But those are just the basics; yes the beauty of Nostr is its ‘simplicity’, but that does not mean the system that results from it is not complex. Conway's Game of Life only has a hand full of rules, yet you can, in theory at least, create any complex system imaginable. And this is where the deception lies; the less you define from the outset, the more you imply on what follows.
It appears that as it stands, Nostr suffers from this deceptiveness. You can reason through all these implications, but that is still an exercise that has to be performed and where mistakes can be made. Worse, this exercise has been a group effort from the start that is still in progress. Currently there is no clear cut ‘authoritative’ example of all the implications that have been ‘discovered’ thus far.
A good example of the implications following Nostr’s primitives is what we now refer to as the ‘outbox model’. The reason we ‘now’ refer to it as such, is because initially it was called the ‘Gossip model’ derived from the client that first implemented the idea. Outbox is fundamental to Nostr, but it was never explicitly stated in the initial protocol description. The result is that roughly five years into this Nostr endeavor, it is still not universally implemented; worse yet, some developers appear to be in no rush to do so. Now the reason they will give you is probably one based on priority, yet I can’t shake the feeling that they apparently don’t ‘get it’.
My point here is not to play some blame game or hold anyone to account. I am just concluding they don’t actually get the new paradigm that we have all stumbled into. To expand on this specific outbox example, its significance only becomes really apparent further along in the ‘reasoning through all the implications’ exercise. In relation to one aspect, but there are more: The point is not ‘just’ censorship-resistance for users, but the freedom for relays that comes with it to apply whatever policy on what they store and make available; it is this discrimination or curation that can add value by making finding relevant information easier in a straightforward manner. But it relies on outbox to avoid isolation; something that only becomes apparent once you are reasoning through all the implications on how we discover and consume content.
To be clear, this piece is not supposed to a crusade on the outbox model, my point here is that there is an inherent logic to Nostr stemming from putting cryptography front and center. It is a logic that has to be applied and will subsequently carry you through all the challenges we face in reconstructing the entirety of the web. This is not to say there is only one obvious path, and different schools of thought are bound to emerge. But it behooves us all, faced with this new paradigm, to continuously reflect on the mental image we have cultivated of what Nostr is; actively re-performing that exercise of exploring the implications this simple set of protocol rules creates.
Unfortunately I can not escape my own folly. After all, I am just an armchair asshole that never wrote a single line of code in his life. Obviously this minds-eye bullshit is not even half the story, the bulk of the effort is translating it into software, the tangible, the real. It is in that effort ultimately the real exploration of this paradigm occurs. All I can do is build castles in the sky.

2024-12-02 20:05:48Benjamin Franklin and His Fondness for Madeira Wine
Benjamin Franklin, one of America’s most celebrated founding fathers, was not only a statesman, scientist, and writer but also a man of refined taste. Among his many indulgences, Franklin was particularly fond of Madeira wine, a fortified wine from the Portuguese Madeira Islands. His love for this drink was well-documented and reflects both his personal preferences and the broader cultural trends of 18th-century America.
The Allure of Madeira Wine
Madeira wine was highly prized in the 18th century due to its unique production process and exceptional durability. Its rich, fortified nature made it well-suited for long sea voyages, as it could withstand temperature fluctuations and aging in transit. This durability made Madeira a popular choice in the American colonies, where European wines often spoiled before arrival.
Franklin, who was known for his appreciation of fine things, embraced Madeira as a beverage of choice. Its complex flavors and storied reputation resonated with his intellectual and social pursuits. The wine was often served at dinners and social gatherings, where Franklin and his contemporaries debated ideas and shaped the future of the nation.
Franklin’s Personal Connection to Madeira
In Franklin’s writings and correspondence, Madeira is mentioned on several occasions, reflecting its prominence in his life. He referred to the wine not only as a personal pleasure but also as a symbol of hospitality and refinement. As a diplomat in France and England, Franklin often carried Madeira to share with his hosts, using it as a means of forging connections and showcasing the tastes of the American colonies.
One notable instance of Franklin’s affinity for Madeira occurred during his time in Philadelphia. He reportedly had cases of the wine shipped directly to his home, ensuring he would never be without his favorite drink. Madeira also featured prominently in many toasts and celebrations, becoming a hallmark of Franklin’s gatherings.
The Role of Madeira in Colonial America
Franklin’s fondness for Madeira reflects its broader significance in colonial America. The wine was not only a favorite of the elite but also a symbol of resistance to British taxation. When the British imposed heavy duties on imported goods, including wine, Madeira became a patriotic choice for many colonists. Its direct trade routes with the Madeira Islands circumvented British intermediaries, allowing Americans to assert their economic independence.
A Legacy of Taste
Franklin’s appreciation for Madeira wine endures as a charming detail of his multifaceted life. It offers a glimpse into the personal habits of one of America’s most influential figures and highlights the cultural exchanges that shaped colonial society. Today, Franklin’s love of Madeira serves as a reminder of the historical connections between wine, politics, and personal expression in the 18th century.
In honoring Franklin’s legacy, one might raise a glass of Madeira to toast not only his contributions to American independence but also his enduring influence on the art of living well.

2025-05-27 07:07:33A few months ago, a nostrich was switching from iOS to Android and asked for suggestions for #Nostr apps to try out. nostr:npub18ams6ewn5aj2n3wt2qawzglx9mr4nzksxhvrdc4gzrecw7n5tvjqctp424 offered the following as his response:
nostr:nevent1qvzqqqqqqypzq0mhp4ja8fmy48zuk5p6uy37vtk8tx9dqdwcxm32sy8nsaa8gkeyqydhwumn8ghj7un9d3shjtnwdaehgunsd3jkyuewvdhk6tcpz4mhxue69uhhyetvv9ujuerpd46hxtnfduhszythwden5te0dehhxarj9emkjmn99uqzpwwts6n28eyvjpcwvu5akkwu85eg92dpvgw7cgmpe4czdadqvnv984rl0z
Yes. #Android users are fortunate to have some powerful Nostr apps and tools at our disposal that simply have no comparison over on the iOS side. However, a tool is only as good as the knowledge of the user, who must have an understanding of how best to wield it for maximum effect. This fact was immediately evidenced by replies to Derek asking, "What is the use case for Citrine?" and "This is the first time I'm hearing about Citrine and Pokey. Can you give me links for those?"
Well, consider this tutorial your Nostr starter-kit for Android. We'll go over installing and setting up Amber, Amethyst, Citrine, and Pokey, and as a bonus we'll be throwing in the Zapstore and Coinos to boot. We will assume no previous experience with any of the above, so if you already know all about one or more of these apps, you can feel free to skip that tutorial.
So many apps...
You may be wondering, "Why do I need so many apps to use Nostr?" That's perfectly valid, and the honest answer is, you don't. You can absolutely just install a Nostr client from the Play Store, have it generate your Nostr identity for you, and stick with the default relays already set up in that app. You don't even need to connect a wallet, if you don't want to. However, you won't experience all that Nostr has to offer if that is as far as you go, any more than you would experience all that Italian cuisine has to offer if you only ever try spaghetti.
Nostr is not just one app that does one thing, like Facebook, Twitter, or TikTok. It is an entire ecosystem of applications that are all built on top of a protocol that allows them to be interoperable. This set of tools will help you make the most out of that interoperability, which you will never get from any of the big-tech social platforms. It will provide a solid foundation for you to build upon as you explore more and more of what Nostr has to offer.
So what do these apps do?
Fundamental to everything you do on Nostr is the need to cryptographically sign with your private key. If you aren't sure what that means, just imagine that you had to enter your password every time you hit the "like" button on Facebook, or every time you commented on the latest dank meme. That would get old really fast, right? That's effectively what Nostr requires, but on steroids.
To keep this from being something you manually have to do every 5 seconds when you post a note, react to someone else's note, or add a comment, Nostr apps can store your private key and use it to sign behind the scenes for you. This is very convenient, but it means you are trusting that app to not do anything with your private key that you don't want it to. You are also trusting it to not leak your private key, because anyone who gets their hands on it will be able to post as you, see your private messages, and effectively be you on Nostr. The more apps you give your private key to, the greater your risk that it will eventually be compromised.
Enter #Amber, an application that will store your private key in only one app, and all other compatible Nostr apps can communicate with it to request a signature, without giving any of those other apps access to your private key.
Most Nostr apps for Android now support logging in and signing with Amber, and you can even use it to log into apps on other devices, such as some of the web apps you use on your PC. It's an incredible tool given to us by nostr:npub1w4uswmv6lu9yel005l3qgheysmr7tk9uvwluddznju3nuxalevvs2d0jr5, and only available for Android users. Those on iPhone are incredibly jealous that they don't have anything comparable, yet.
Speaking of nostr:npub1w4uswmv6lu9yel005l3qgheysmr7tk9uvwluddznju3nuxalevvs2d0jr5, the next app is also one of his making.
All Nostr data is stored on relays, which are very simple servers that Nostr apps read notes from and write notes to. In most forms of social media, it can be a pain to get your own data out to keep a backup. That's not the case on Nostr. Anyone can run their own relay, either for the sake of backing up their personal notes, or for others to post their notes to, as well.
Since Nostr notes take up very little space, you can actually run a relay on your phone. I have been on Nostr for almost 2 and a half years, and I have 25,000+ notes of various kinds on my relay, and a backup of that full database is just 24MB on my phone's storage.
Having that backup can save your bacon if you try out a new Nostr client and it doesn't find your existing follow list for some reason, so it writes a new one and you suddenly lose all of the people you were following. Just pop into your #Citrine relay, confirm it still has your correct follow list or import it from a recent backup, then have Citrine restore it. Done.
Additionally, there are things you may want to only save to a relay you control, such as draft messages that you aren't ready to post publicly, or eCash tokens, which can actually be saved to Nostr relays now. Citrine can also be used with Amber for signing into certain Nostr applications that use a relay to communicate with Amber.
If you are really adventurous, you can also expose Citrine over Tor to be used as an outbox relay, or used for peer-to-peer private messaging, but that is far more involved than the scope of this tutorial series.
You can't get far in Nostr without a solid and reliable client to interact with. #Amethyst is the client we will be using for this tutorial because there simply isn't another Android client that comes close, so far. Moreover, it can be a great client for new users to get started on, and yet it has a ton of features for power-users to take advantage of as well.
There are plenty of other good clients to check out over time, such as Coracle, YakiHonne, Voyage, Olas, Flotilla and others, but I keep coming back to Amethyst, and by the time you finish this tutorial, I think you'll see why. nostr:npub1gcxzte5zlkncx26j68ez60fzkvtkm9e0vrwdcvsjakxf9mu9qewqlfnj5z and others who have contributed to Amethyst have really built something special in this client, and it just keeps improving with every update that's shipped.
Most social media apps have some form of push notifications, and some Nostr apps do, too. Where the issue comes in is that Nostr apps are all interoperable. If you have more than one application, you're going to have both of them notifying you. Nostr users are known for having five or more Nostr apps that they use regularly. If all of them had notifications turned on, it would be a nightmare. So maybe you limit it to only one of your Nostr apps having notifications turned on, but then you are pretty well locked-in to opening that particular app when you tap on the notification.
Pokey, by nostr:npub1v3tgrwwsv7c6xckyhm5dmluc05jxd4yeqhpxew87chn0kua0tjzqc6yvjh, solves this issue, allowing you to turn notifications off for all of your Nostr apps, and have Pokey handle them all for you. Then, when you tap on a Pokey notification, you can choose which Nostr app to open it in.
Pokey also gives you control over the types of things you want to be notified about. Maybe you don't care about reactions, and you just want to know about zaps, comments, and direct messages. Pokey has you covered. It even supports multiple accounts, so you can get notifications for all the npubs you control.
One of the most unique and incredibly fun aspects of Nostr is the ability to send and receive #zaps. Instead of merely giving someone a 👍️ when you like something they said, you can actually send them real value in the form of sats, small portions of a Bitcoin. There is nothing quite like the experience of receiving your first zap and realizing that someone valued what you said enough to send you a small amount (and sometimes not so small) of #Bitcoin, the best money mankind has ever known.
To be able to have that experience, though, you are going to need a wallet that can send and receive zaps, and preferably one that is easy to connect to Nostr applications. My current preference for that is Alby Hub, but not everyone wants to deal with all that comes along with running a #Lightning node. That being the case, I have opted to use nostr:npub1h2qfjpnxau9k7ja9qkf50043xfpfy8j5v60xsqryef64y44puwnq28w8ch for this tutorial, because they offer one of the easiest wallets to set up, and it connects to most Nostr apps by just copy/pasting a connection string from the settings in the wallet into the settings in your Nostr app of choice.
Additionally, even though #Coinos is a custodial wallet, you can have it automatically transfer any #sats over a specified threshold to a separate wallet, allowing you to mitigate the custodial risk without needing to keep an eye on your balance and make the transfer manually.
Most of us on Android are used to getting all of our mobile apps from one souce: the Google Play Store. That's not possible for this tutorial series. Only one of the apps mentioned above is available in Google's permissioned playground. However, on Android we have the advantage of being able to install whatever we want on our device, just by popping into our settings and flipping a toggle. Indeed, thumbing our noses at big-tech is at the heart of the Nostr ethos, so why would we make ourselves beholden to Google for installing Nostr apps?
The nostr:npub10r8xl2njyepcw2zwv3a6dyufj4e4ajx86hz6v4ehu4gnpupxxp7stjt2p8 is an alternative app store made by nostr:npub1wf4pufsucer5va8g9p0rj5dnhvfeh6d8w0g6eayaep5dhps6rsgs43dgh9 as a resource for all sorts of open-source apps, but especially Nostr apps. What is more, you can log in with Amber, connect a wallet like Coinos, and support the developers of your favorite Nostr apps directly within the #Zapstore by zapping their app releases.
One of the biggest features of the Zapstore is the fact that developers can cryptographically sign their app releases using their Nostr keys, so you know that the app you are downloading is the one they actually released and hasn't been altered in any way. The Zapstore will warn you and won't let you install the app if the signature is invalid.
Getting Started
Since the Zapstore will be the source we use for installing most of the other apps mentioned, we will start with installing the Zapstore.
We will then use the Zapstore to install Amber and set it up with our Nostr account, either by creating a new private key, or by importing one we already have. We'll also use it to log into the Zapstore.
Next, we will install Amethyst from the Zapstore and log into it via Amber.
After this, we will install Citrine from the Zapstore and add it as a local relay on Amethyst.
Because we want to be able to send and receive zaps, we will set up a wallet with CoinOS and connect it to Amethyst and the Zapstore using Nostr Wallet Connect.
Finally, we will install Pokey using the Zapstore, log into it using Amber, and set up the notifications we want to receive.
By the time you are done with this series, you will have a great head-start on your Nostr journey compared to muddling through it all on your own. Moreover, you will have developed a familiarity with how things generally work on Nostr that can be applied to other apps you try out in the future.

2025-05-27 02:24:08I did pretty poorly today. It's dreary and drizzly here, so I didn't get out walking. Even the dog didn't want to go out. We also had weirdly few chores or errands to do.
Maybe this was just a natural rest day. I did catch up on some sleep.
Foodwise, I kept my fast until reasonably late in the day, but then I ate a bunch of cookies. I'll need to do better tomorrow.
How'd everyone else do, today?

2025-05-25 01:03:51บางครั้งพลังยิ่งใหญ่ที่สุดก็ไม่ใช่สิ่งที่เห็นได้ด้วยตาเปล่า เหมือนแสงแดดที่คนส่วนใหญ่มักจะกลัวเพราะกลัวผิวเสีย กลัวฝ้า กลัวร้อน แต่แท้จริงแล้วในแสงแดดมีบางสิ่งที่น่าเคารพอยู่ลึกๆ มันคือแสงที่มองไม่เห็น มันไม่แสบตา ไม่แสบผิว แต่มันลึก ถึงเซลล์ มันคือ “แสงอินฟราเรด” ที่ซ่อนตัวอย่างสุภาพในแดดยามเช้า
เฮียมักชอบพูดว่า แดดที่ดีไม่จำเป็นต้องแสบหลัง อาบแสงที่ลอดผ่านใบไม้ยามเช้าแบบไม่ต้องฝืนตาก็พอ แสงอินฟราเรดนี่แหละคือพระเอกตัวจริงในความเงียบ มันไม่ดัง ไม่โชว์ ไม่โฆษณา แต่มันลงลึกไปถึงระดับที่ร่างกายเรากำลังหิวโดยไม่รู้ตัวในระดับเซลล์
ในเซลล์ของเรา มีหน่วยผลิตพลังงานที่เรียกว่าไมโทคอนเดรีย เจ้านี่แหละคือโรงไฟฟ้าจิ๋วประจำบ้าน ที่ต้องตื่นมาทำงานทุกวันโดยไม่ได้หยุดเสาร์อาทิตย์ ยิ่งถ้าไมโทคอนเดรียทำงานไม่ดี ร่างกายก็จะเหมือนไฟตกทั้งระบบ—ง่วงง่าย เพลียไว ปวดนู่นปวดนี่เหมือนไฟในบ้านกระพริบตลอดเวลา
แล้วแสงอินฟราเรดเกี่ยวอะไรกับมัน? เฮียขอเล่าง่ายๆ ว่า ไมโทคอนเดรียมีตัวรับแสงตัวหนึ่งชื่อว่า cytochrome c oxidase เจ้านี่ตอบสนองต่อแสงอินฟราเรดช่วงคลื่นเฉพาะ คือประมาณ 600–900 นาโนเมตร พอโดนเข้าไป มันเหมือนได้จุดประกายให้โรงงานพลังงานในร่างกายกลับมาคึกคักอีกครั้ง ผลิตพลังงานได้มากขึ้น ระบบไหลเวียนเลือดก็ดีขึ้น เหมือนท่อน้ำที่เคยอุดตันก็กลับมาใสแจ๋ว ความอักเสบเล็กๆ ในร่างกายก็ลดลง คล้ายบ้านที่เคยอับชื้นแล้วได้เปิดหน้าต่างให้แสงแดดส่องเข้าไป
และที่น่ารักกว่านั้นคือ เราไม่ต้องไปถึงชายหาด ไม่ต้องจองรีสอร์ตริมทะเล แค่แดดเช้าอ่อนๆ ข้างบ้านหรือตามขอบระเบียง ก็ให้แสงอินฟราเรดได้แล้ว ถ้าใครอยู่ในเมืองใหญ่ที่มีแต่ตึกบังแดด แล้วจะเลือกใช้หลอดไฟ Red Light Therapy ก็ไม่ผิด แต่ต้องเลือกแบบรู้เท่าทันรู้ ไม่ใช่เห็นใครรีวิวก็ซื้อมาเปิดใส่หน้า หวังจะหน้าใสข้ามคืน ต้องเข้าใจทั้งความยาวคลื่น เวลาใช้งาน และจุดประสงค์ ไม่ใช่ใช้เพราะแค่กลัวแก่อยากหน้าตึง แต่ใช้เพราะอยากให้ร่างกายกลับไปทำงานอย่างเป็นธรรมชาติอีกครั้ง และอยู่ในประเทศหรือสถานที่ที่โดนแดดได้น้อยอยากได้เสริมเฉยๆ
แล้วเราจะรู้ได้ยังไงว่าไมโทคอนเดรียเรากลับมาทำงานดีขึ้น? เฮียว่าไม่ต้องรอผลเลือดจากแล็บไหนก็รู้ได้ อย่าไปยึดติดกับตัวเลขมากครับ เอาตัวเองเป็นหลัก ตั้งคำถามกับตัวเองว่ารู้สึกยังไงบ้าง ถ้าเริ่มนอนหลับลึกขึ้น ตื่นมาแล้วหัวไม่มึน ไม่หงุดหงิดตั้งแต่ยังไม่ลืมตา ถ้าปวดหลังปวดข้อที่เคยมีเริ่มหายไปแบบไม่ได้กินยา หรือแม้แต่ผิวที่ดูสดใสขึ้นแบบไม่ต้องง้อสกินแคร์ นั่นแหละคือเสียงขอบคุณเบาๆ จากไมโทคอนเดรียที่ได้แสงแดดแล้วกลับมามีชีวิตอีกครั้ง ถ้ามันดีก็คือดี
บางที เราไม่ต้องกินวิตามินเม็ดไหนเพิ่ม แค่เดินออกไปรับแดดเบาๆ ในเวลาเช้าๆ แล้วให้ร่างกายได้พูดคุยกับธรรมชาติบ้าง เพราะในความอบอุ่นเงียบๆ ของแสงอินฟราเรดนั้น มีเสียงเบาๆ ที่กำลังปลุกพลังในตัวเราให้กลับมาอีกครั้ง
แดดไม่ใช่ศัตรู ถ้าเรารู้จักมันในมุมที่ถูกต้อง เฮียแค่อยากชวนให้ลองเปลี่ยนจากคำว่า “กลัวแดด” เป็น “ฟังแดด” เพราะบางครั้งธรรมชาติไม่ได้พูดด้วยคำ แต่สื่อสารด้วยแสงที่แทรกผ่านหัวใจเราโดยไม่ต้องผ่านล่าม
บางคนอาจคิดในใจ “แหมเฮีย ก็ดีหรอก ถ้าได้ตื่นเช้า” 555555
เฮียเข้าใจดีเลยว่าไม่ใช่ทุกคนจะตื่นมาทันแดดยามเช้าได้เสมอไป ชีวิตคนเรามันไม่ได้เริ่มต้นพร้อมไก่ขันทุกวัน บางคนเพิ่งเข้านอนตอนตีสาม ตื่นอีกทีแดดก็แตะบ่ายเข้าไปแล้ว ไม่ต้องกังวลไปจ้ะ เพราะความมหัศจรรย์ของแสงอินฟราเรดยังมีให้เราได้ใช้แม้ในแดดยามเย็น
แดดช่วงเย็น โดยเฉพาะหลังสี่โมงเย็นไปจนเกือบหกโมง (หรือเร็วช้าตามฤดู) ก็ยังอุดมไปด้วยแสงอินฟราเรดในช่วงคลื่นที่ไมโทคอนเดรียชอบ แถมยังไม่มีรังสี UV ที่แรงจัดมารบกวนเหมือนตอนเที่ยง เรียกว่าเป็นแดดแบบละมุนๆ สำหรับคนที่อยาก “บำบัดใจ” แบบไม่ต้องร้อนจนหัวเปียก
เฮียเคยลองตากแดดเย็นเดินไปในสวนสาธารณะ แล้วรู้สึกว่ามันเหมือนได้รีเซ็ตจิตใจหลังวันเหนื่อยๆ ไปในตัว ยิ่งพอรู้ว่าในช่วงเวลานี้แสงที่ได้กำลังช่วยปลุกพลังงานในร่างกายแบบเงียบๆ ด้วยแล้ว มันทำให้เฮียยิ่งเคารพธรรมชาติมากขึ้นไปอีก เคยเห็นคนที่วันๆมีแต่ความเครียด ความโกรธ ความอาฆาตต่อโลกไหมหละ บางคนแค่โดนแดด แต่ไม่ได้ตากแดด การตากแดดคือปล่อยใจไปกับธรรมชาติ พูดคุยกับร่างกาย บอกเขาว่าเราจะทำตัวให้เป็นประโยชน์กับโลกใบนี้ ให้สมกับที่ใช้พลังงานของโลก
จะเช้าหรือเย็น สำคัญไม่เท่ากับความตั้งใจ เฮียว่าไม่ว่าชีวิตจะตื่นตอนไหน ถ้าเราให้เวลาแค่ 10–15 นาทีในแต่ละวัน ออกไปยืนให้แดดแตะหน้า แตะแขน หรือแค่ให้แสงลอดผ่านตาเบาๆ โดยไม่ต้องจ้องจ้าๆ ก็พอ แค่นี้ก็เป็นการให้ไมโทคอนเดรียได้หายใจ ได้ออกกำลังกายแบบของมัน และได้ส่งพลังกลับมาหาเราทั้งร่างกายและจิตใจ
สุดท้ายแล้ว แดดไม่ได้แบ่งชนชั้น ไม่เลือกว่าจะรักเฉพาะคนตื่นเช้า หรือโกรธคนตื่นสาย ขอแค่เรารู้จักเวลาและวิธีอยู่กับมันอย่างถูกจังหวะ แดดก็พร้อมจะให้เสมอ

2024-11-29 13:26:00The Weaponization of Technology: A Prelude to Adoption
Throughout history, new technologies have often been weaponized before becoming widely adopted for civilian use. This pattern, deeply intertwined with human priorities for power, survival, and dominance, sheds light on how societies interact with technological innovation.
The Weaponization Imperative
When a groundbreaking technology emerges, its potential to confer an advantage—military, economic, or ideological—tends to attract attention from those in power. Governments and militaries, seeking to outpace rivals, often invest heavily in adapting new tools for conflict or defense. Weaponization provides a context where innovation thrives under high-stakes conditions. Technologies like radar, nuclear energy, and the internet, initially conceived or expanded within the framework of military priorities, exemplify this trend.
Historical Examples
1. Gunpowder: Invented in 9th-century China, gunpowder was first used for military purposes before transitioning into civilian life, influencing mining, construction, and entertainment through fireworks.
-
The Internet: Initially developed as ARPANET during the Cold War to ensure communication in the event of a nuclear attack, the internet’s infrastructure later supported the global digital revolution, reshaping commerce, education, and social interaction.
-
Drones: Unmanned aerial vehicles began as tools of surveillance and warfare but have since been adopted for everything from package delivery to agricultural monitoring.
Weaponization often spurs rapid technological development. War environments demand urgency and innovation, fast-tracking research and turning prototypes into functional tools. This phase of militarization ensures that the technology is robust, scalable, and often cost-effective, setting the stage for broader adoption.
Adoption and Civilian Integration
Once a technology’s military dominance is established, its applications often spill into civilian life. These transitions occur when:
• The technology becomes affordable and accessible. • Governments or corporations recognize its commercial potential. • Public awareness and trust grow, mitigating fears tied to its military origins.
For example, GPS was first a military navigation system but is now indispensable for personal devices, logistics, and autonomous vehicles.
Cultural Implications
The process of weaponization shapes public perception of technology. Media narratives, often dominated by stories of power and conflict, influence how societies view emerging tools. When technologies are initially seen through the lens of violence or control, their subsequent integration into daily life can carry residual concerns, from privacy to ethical implications.
Conclusion
The weaponization of technology is not an aberration but a recurring feature of technological progress. By understanding this pattern, societies can critically assess how technologies evolve from tools of conflict to instruments of everyday life, ensuring that ethical considerations and equitable access are not lost in the rush to innovate. As Marshall McLuhan might suggest, the medium through which a technology is introduced deeply influences the message it ultimately conveys to the world.

- Nostr is an open and interoperable protocol
- You can integrate it with workflow automation tools to augment your experience
- n8n is a great low/no-code workflow automation tool which you can host yourself
- Nostrobots allows you to integrate Nostr into n8n
- In this blog I create some workflow automations for Nostr
- A simple form to delegate posting notes
- Push notifications for mentions on multiple accounts
- Push notifications for your favourite accounts when they post a note
- All workflows are provided as open source with MIT license for you to use
Inter-op All The Things
Nostr is a new open social protocol for the internet. This open nature exciting because of the opportunities for interoperability with other technologies. In Using NFC Cards with Nostr I explored the
nostr:
URI to launch Nostr clients from a card tap.The interoperability of Nostr doesn't stop there. The internet has many super-powers, and Nostr is open to all of them. Simply, there's no one to stop it. There is no one in charge, there are no permissioned APIs, and there are no risks of being de-platformed. If you can imagine technologies that would work well with Nostr, then any and all of them can ride on or alongside Nostr rails.
My mental model for why this is special is Google Wave ~2010. Google Wave was to be the next big platform. Lars was running it and had a big track record from Maps. I was excited for it. Then, Google pulled the plug. And, immediately all the time and capital invested in understanding and building on the platform was wasted.
This cannot happen to Nostr, as there is no one to pull the plug, and maybe even no plug to pull.
So long as users demand Nostr, Nostr will exist, and that is a pretty strong guarantee. It makes it worthwhile to invest in bringing Nostr into our other applications.
All we need are simple ways to plug things together.
Nostr and Workflow Automation
Workflow automation is about helping people to streamline their work. As a user, the most common way I achieve this is by connecting disparate systems together. By setting up one system to trigger another or to move data between systems, I can solve for many different problems and become way more effective.
n8n for workflow automation
Many workflow automation tools exist. My favourite is n8n. n8n is a low/no-code workflow automation platform which allows you to build all kinds of workflows. You can use it for free, you can self-host it, it has a user-friendly UI and useful API. Vs Zapier it can be far more elaborate. Vs Make.com I find it to be more intuitive in how it abstracts away the right parts of the code, but still allows you to code when you need to.
Most importantly you can plug anything into n8n: You have built-in nodes for specific applications. HTTP nodes for any other API-based service. And community nodes built by individual community members for any other purpose you can imagine.
Eating my own dogfood
It's very clear to me that there is a big design space here just demanding to be explored. If you could integrate Nostr with anything, what would you do?
In my view the best way for anyone to start anything is by solving their own problem first (aka "scratching your own itch" and "eating your own dogfood"). As I get deeper into Nostr I find myself controlling multiple Npubs – to date I have a personal Npub, a brand Npub for a community I am helping, an AI assistant Npub, and various testing Npubs. I need ways to delegate access to those Npubs without handing over the keys, ways to know if they're mentioned, and ways to know if they're posting.
I can build workflows with n8n to solve these issues for myself to start with, and keep expanding from there as new needs come up.
Running n8n with Nostrobots
I am mostly non-technical with a very helpful AI. To set up n8n to work with Nostr and operate these workflows should be possible for anyone with basic technology skills.
- I have a cheap VPS which currently runs my HAVEN Nostr Relay and Albyhub Lightning Node in Docker containers,
- My objective was to set up n8n to run alongside these in a separate Docker container on the same server, install the required nodes, and then build and host my workflows.
Installing n8n
Self-hosting n8n could not be easier. I followed n8n's Docker-Compose installation docs–
- Install Docker and Docker-Compose if you haven't already,
- Create your
docker-compose.yml
and.env
files from the docs, - Create your data folder
sudo docker volume create n8n_data
, - Start your container with
sudo docker compose up -d
, - Your n8n instance should be online at port
5678
.
n8n is free to self-host but does require a license. Enter your credentials into n8n to get your free license key. You should now have access to the Workflow dashboard and can create and host any kind of workflows from there.
Installing Nostrobots
To integrate n8n nicely with Nostr, I used the Nostrobots community node by Ocknamo.
In n8n parlance a "node" enables certain functionality as a step in a workflow e.g. a "set" node sets a variable, a "send email" node sends an email. n8n comes with all kinds of "official" nodes installed by default, and Nostr is not amongst them. However, n8n also comes with a framework for community members to create their own "community" nodes, which is where Nostrobots comes in.
You can only use a community node in a self-hosted n8n instance (which is what you have if you are running in Docker on your own server, but this limitation does prevent you from using n8n's own hosted alternative).
To install a community node, see n8n community node docs. From your workflow dashboard–
- Click the "..." in the bottom left corner beside your username, and click "settings",
- Cilck "community nodes" left sidebar,
- Click "Install",
- Enter the "npm Package Name" which is
n8n-nodes-nostrobots
, - Accept the risks and click "Install",
- Nostrobots is now added to your n8n instance.
Using Nostrobots
Nostrobots gives you nodes to help you build Nostr-integrated workflows–
- Nostr Write – for posting Notes to the Nostr network,
- Nostr Read – for reading Notes from the Nostr network, and
- Nostr Utils – for performing certain conversions you may need (e.g. from bech32 to hex).
Nostrobots has good documentation on each node which focuses on simple use cases.
Each node has a "convenience mode" by default. For example, the "Read" Node by default will fetch Kind 1 notes by a simple filter, in Nostrobots parlance a "Strategy". For example, with Strategy set to "Mention" the node will accept a pubkey and fetch all Kind 1 notes that Mention the pubkey within a time period. This is very good for quick use.
What wasn't clear to me initially (until Ocknamo helped me out) is that advanced use cases are also possible.
Each node also has an advanced mode. For example, the "Read" Node can have "Strategy" set to "RawFilter(advanced)". Now the node will accept json (anything you like that complies with NIP-01). You can use this to query Notes (Kind 1) as above, and also Profiles (Kind 0), Follow Lists (Kind 3), Reactions (Kind 7), Zaps (Kind 9734/9735), and anything else you can think of.
Creating and adding workflows
With n8n and Nostrobots installed, you can now create or add any kind of Nostr Workflow Automation.
- Click "Add workflow" to go to the workflow builder screen,
- If you would like to build your own workflow, you can start with adding any node. Click "+" and see what is available. Type "Nostr" to explore the Nostrobots nodes you have added,
- If you would like to add workflows that someone else has built, click "..." in the top right. Then click "import from URL" and paste in the URL of any workflow you would like to use (including the ones I share later in this article).
Nostr Workflow Automations
It's time to build some things!
A simple form to post a note to Nostr
I started very simply. I needed to delegate the ability to post to Npubs that I own in order that a (future) team can test things for me. I don't want to worry about managing or training those people on how to use keys, and I want to revoke access easily.
I needed a basic form with credentials that posted a Note.
For this I can use a very simple workflow–
- A n8n Form node – Creates a form for users to enter the note they wish to post. Allows for the form to be protected by a username and password. This node is the workflow "trigger" so that the workflow runs each time the form is submitted.
- A Set node – Allows me to set some variables, in this case I set the relays that I intend to use. I typically add a Set node immediately following the trigger node, and put all the variables I need in this. It helps to make the workflows easier to update and maintain.
- A Nostr Write node (from Nostrobots) – Writes a Kind-1 note to the Nostr network. It accepts Nostr credentials, the output of the Form node, and the relays from the Set node, and posts the Note to those relays.
Once the workflow is built, you can test it with the testing form URL, and set it to "Active" to use the production form URL. That's it. You can now give posting access to anyone for any Npub. To revoke access, simply change the credentials or set to workflow to "Inactive".
It may also be the world's simplest Nostr client.
You can find the Nostr Form to Post a Note workflow here.
Push notifications on mentions and new notes
One of the things Nostr is not very good at is push notifications. Furthermore I have some unique itches to scratch. I want–
- To make sure I never miss a note addressed to any of my Npubs – For this I want a push notification any time any Nostr user mentions any of my Npubs,
- To make sure I always see all notes from key accounts – For this I need a push notification any time any of my Npubs post any Notes to the network,
- To get these notifications on all of my devices – Not just my phone where my Nostr regular client lives, but also on each of my laptops to suit wherever I am working that day.
I needed to build a Nostr push notifications solution.
To build this workflow I had to string a few ideas together–
- Triggering the node on a schedule – Nostrobots does not include a trigger node. As every workflow starts with a trigger we needed a different method. I elected to run the workflow on a schedule of every 10-minutes. Frequent enough to see Notes while they are hot, but infrequent enough to not burden public relays or get rate-limited,
- Storing a list of Npubs in a Nostr list – I needed a way to store the list of Npubs that trigger my notifications. I initially used an array defined in the workflow, this worked fine. Then I decided to try Nostr lists (NIP-51, kind 30000). By defining my list of Npubs as a list published to Nostr I can control my list from within a Nostr client (e.g. Listr.lol or Nostrudel.ninja). Not only does this "just work", but because it's based on Nostr lists automagically Amethyst client allows me to browse that list as a Feed, and everyone I add gets notified in their Mentions,
- Using specific relays – I needed to query the right relays, including my own HAVEN relay inbox for notes addressed to me, and wss://purplepag.es for Nostr profile metadata,
- Querying Nostr events (with Nostrobots) – I needed to make use of many different Nostr queries and use quite a wide range of what Nostrobots can do–
- I read the EventID of my Kind 30000 list, to return the desired pubkeys,
- For notifications on mentions, I read all Kind 1 notes that mention that pubkey,
- For notifications on new notes, I read all Kind 1 notes published by that pubkey,
- Where there are notes, I read the Kind 0 profile metadata event of that pubkey to get the displayName of the relevant Npub,
- I transform the EventID into a Nevent to help clients find it.
- Using the Nostr URI – As I did with my NFC card article, I created a link with the
nostr:
URI prefix so that my phone's native client opens the link by default, - Push notifications solution – I needed a push notifications solution. I found many with n8n integrations and chose to go with Pushover which supports all my devices, has a free trial, and is unfairly cheap with a $5-per-device perpetual license.
Once the workflow was built, lists published, and Pushover installed on my phone, I was fully set up with push notifications on Nostr. I have used these workflows for several weeks now and made various tweaks as I went. They are feeling robust and I'd welcome you to give them a go.
You can find the Nostr Push Notification If Mentioned here and If Posts a Note here.
In speaking with other Nostr users while I was building this, there are all kind of other needs for push notifications too – like on replies to a certain bookmarked note, or when a followed Npub starts streaming on zap.stream. These are all possible.
Use my workflows
I have open sourced all my workflows at my Github with MIT license and tried to write complete docs, so that you can import them into your n8n and configure them for your own use.
To import any of my workflows–
- Click on the workflow of your choice, e.g. "Nostr_Push_Notify_If_Mentioned.json",
- Click on the "raw" button to view the raw JSON, ex any Github page layout,
- Copy that URL,
- Enter that URL in the "import from URL" dialog mentioned above.
To configure them–
- Prerequisites, credentials, and variables are all stated,
- In general any variables required are entered into a Set Node that follows the trigger node,
- Pushover has some extra setup but is very straightforward and documented in the workflow.
What next?
Over my first four blogs I explored creating a good Nostr setup with Vanity Npub, Lightning Payments, Nostr Addresses at Your Domain, and Personal Nostr Relay.
Then in my latest two blogs I explored different types of interoperability with NFC cards and now n8n Workflow Automation.
Thinking ahead n8n can power any kind of interoperability between Nostr and any other legacy technology solution. On my mind as I write this:
- Further enhancements to posting and delegating solutions and forms (enhanced UI or different note kinds),
- Automated or scheduled posting (such as auto-liking everything Lyn Alden posts),
- Further enhancements to push notifications, on new and different types of events (such as notifying me when I get a new follower, on replies to certain posts, or when a user starts streaming),
- All kinds of bridges, such as bridging notes to and from Telegram, Slack, or Campfire. Or bridging RSS or other event feeds to Nostr,
- All kinds of other automation (such as BlackCoffee controlling a coffee machine),
- All kinds of AI Assistants and Agents,
In fact I have already released an open source workflow for an AI Assistant, and will share more about that in my next blog.
Please be sure to let me know if you think there's another Nostr topic you'd like to see me tackle.

2024-12-08 09:05:13Yalnızca güçlü olanların hakkıdır yaşamak.
Güçlü olan ileri gider ve saflar seyrekleşir. Ama üç beş büyük, güçlü ve tanrısal kişi güneşli ve aydınlık gözleriyle o yeni, o vaat edilmiş ülkeye ulaşacaktır. Belki binlerce yıl sonra ancak. Ve güçlü, adaleli, hükmetmek için yaratılmış elleriyle hastaların, zayıfların ve sakatların ölüleri üzerinde bir krallık kuracaklardır. Bir krallık!
Benim aradığım insanların kendileri değil, sesleridir.
Duyguları körelmiş, çeşitli düşüncelere saplanmış kalabalık hiçbir zaman ilerlemenin taşıyıcısı olamaz, kendi küçüklüğünün o küflü içgüdüsüyle kalabalığın kin ve nefretle baktığı bir kişi, bir büyük kişi, iradesinin gösterdiği yolda kimsenin gözünün yaşına bakmaksızın ilahi bir güç ve bir zafer gülümsemesiyle yürüyebilir ancak.
Bizim soyumuz da sonsuz oluşum piramidinin doruk noktasını oluşturmaktan uzaktır. Bizler de mükemmelliğe ulaşmış değiliz. Bizler de henüz olgunlaşmadık.
Şairler sevgiye övgüler döşenir; doğrusu sevginin güçlü bir şey olduğu kesin. Hüneşin bir ışınıdır sevgi, aydınlatıp nurlandırır insanı der bazıları; bazıları da insanı esrikliğe sürükleyen bir zehri kendisinde barındırdığını söyler. Gerçekten de yol açtığı sonuçlar, bir hekimin ağır bir ameliyattan önce korkudan titreyen hastaya teneffüs ettirdiği güldürücü gazınkine benzer, içinde tepinip duran acıyı unutturur hastaya.
Önemli olan, hayatta hiç değilse bir kez kutsal bir ilkbaharın yaşanmasıdır; öyle bir bahar ki, insanın gönlünü ilerideki bütün günleri altın yaldızla kaplamaya yetecek kadar ışık ve parıltıyla doldursun.
Şu hayat denen şey kötü bir işçiliğin ürünü, acemilere göre bir şey. Bu kepaze yaşam uğruna insan nelere katlanmıyor ki!
Kendisine sadakatten ayrılmadığı, yalnızca kendisinin olan bir tek bu var: Yalnızlığı.
Sahildeki üstü tenteli hasır koltuklar arkasındaki yüksek, sessiz kum tepeleri içinde yürürsen, tenteler altındaki insanları göremezsin; ama birinin bir diğerine seslendiğini, bir başkasının gevezelik ettiğini, bir ötekinin güldüğünü işitir ve anlarsın hemen: bu insan şöyle şöyle biridir diyebilirsin. Onun hayatı sevdiğini, bağrında büyük bir özlem ya da acı barındırdığını, bu acının da sesini ağlamaklı kıldığını her gülüşünde hissedersin.

2025-05-26 21:52:12A self help book with a dumb title arrived at our house. It was about making more money for people who are terrible at personal finance. I suspect the author is pretty good at making money, though.
It turned out to be my mother-in-law's book that she sent to the wrong address. So, now even more money needs to be spent on getting this stupid book to her house.
Why does a woman who should be retired need such a book, anyway? Only because she and her husband, despite having both worked long semi-prestigious careers, have no assets between them and they live so far beyond their means (retirement accounts and pensions worth about 2x the median family income) that she needs to continue earning greater and greater income.
In her 70's, she embarked on a new career and is attempting to build up her own business around it. However, being terrible at managing finances has led her to reading dumb generic self help books in a hopeless attempt to make her business profitable before she is no longer able to work. It's a ridiculous situation.
Stay humble and stack sats, so you aren't reading dumb self help books about earning more money when you should be long retired.

2025-05-24 01:14:43ในสายตาคนรักสุขภาพทั่วโลก “อโวคาโด” คือผลไม้ในฝัน มันมีไขมันดี มีไฟเบอร์สูง ช่วยลดคอเลสเตอรอลได้ มีวิตามินอี มีโพแทสเซียม และที่สำคัญคือ "ดูดี" ทุกครั้งที่ถูกปาดวางบนขนมปังโฮลวีตในชามสลัด หรือบนโฆษณาอาหารคลีนสุดหรู
แต่ในสายตาชาวไร่บางคนในเม็กซิโกหรือชุมชนพื้นเมืองในโดมินิกัน อโวคาโดไม่ใช่ผลไม้แห่งสุขภาพ แต่มันคือสัญลักษณ์ของความรุนแรง การกดขี่ และการสูญเสียเสรีภาพในผืนดินของตัวเอง
เมื่ออาหารกลายเป็นทองคำ กลุ่มอิทธิพลก็ไม่เคยพลาดจะเข้าครอบครอง
เรามักได้ยินคำว่า "ทองคำเขียว" หรือ Green Gold ใช้เรียกอโวคาโด เพราะในรอบ 20 ปีที่ผ่านมา ความต้องการบริโภคของมันพุ่งสูงขึ้นเป็นเท่าตัว โดยเฉพาะในสหรัฐฯ และยุโรป จากผลการวิจัยของมหาวิทยาลัยฮาร์วาร์ดและข้อมูลการส่งออกของ USDA พบว่า 90% ของอโวคาโดที่บริโภคในอเมริกา มาจากรัฐมิโชอากังของเม็กซิโก พื้นที่ซึ่งควบคุมโดยกลุ่มค้ายาเสพติดไม่ต่างจากเจ้าของสวนตัวจริง
พวกเขาเรียกเก็บ “ค่าคุ้มครอง” จากเกษตรกร โดยใช้วิธีเดียวกับมาเฟีย คือ ถ้าไม่จ่าย ก็เจ็บตัวหรือหายตัว ไม่ว่าจะเป็นกลุ่ม CJNG (Jalisco New Generation Cartel), Familia Michoacana หรือ Caballeros Templarios พวกเขาไม่ได้สนใจว่าใครปลูกหรือใครรดน้ำ ตราบใดที่ผลผลิตสามารถเปลี่ยนเป็นเงินได้
องค์กรอาชญากรรมเหล่านี้ไม่ได้แค่ “แฝงตัว” ในอุตสาหกรรม แต่ ยึดครอง ห่วงโซ่การผลิตทั้งหมด ตั้งแต่แปลงปลูกไปจนถึงโรงบรรจุและเส้นทางขนส่ง คนที่ไม่ยอมเข้าระบบมืดอาจต้องพบจุดจบในป่า หรือไม่มีชื่ออยู่ในทะเบียนบ้านอีกต่อไป
จากรายงานของเว็บไซต์ Food is Power องค์กรไม่แสวงกำไรด้านความยุติธรรมด้านอาหารในสหรัฐฯ เผยว่า ในปี 2020 มีเกษตรกรในเม็กซิโกจำนวนมากที่ถูกข่มขู่ บางรายถึงขั้นถูกฆาตกรรม เพราะปฏิเสธจ่ายค่าคุ้มครองจากกลุ่มค้ายา
การปลูกอโวคาโดไม่ใช่เรื่องเบาๆ กับธรรมชาติ เพราะมันต้องการ “น้ำ” มากถึง 272 ลิตรต่อผลเดียว! เรามาดูว่า “272 ลิตร” นี้ เท่ากับอะไรบ้างในชีวิตจริง อาบน้ำฝักบัวนาน 10–12 นาที (โดยเฉลี่ยใช้น้ำ 20–25 ลิตรต่อนาที) ใช้น้ำซักเสื้อผ้าเครื่องหนึ่ง (เครื่องซักผ้า 1 ครั้งกินประมาณ 60–100 ลิตร) น้ำดื่มของคนหนึ่งคนได้นานเกือบ เดือน (คนเราต้องการน้ำดื่มประมาณ 1.5–2 ลิตรต่อวัน)
ถ้าเราใช้ข้อมูลจาก FAO และ Water Footprint Network การผลิตเนื้อวัว 1 กิโลกรัม ต้องใช้น้ำ 15,000 ลิตร (รวมทั้งการปลูกหญ้า อาหารสัตว์ การดื่มน้ำของวัว ฯลฯ) ได้โปรตีนราว 250 กรัม อโวคาโด 1 กิโลกรัม (ราว 5 ผล) ใช้น้ำประมาณ 1,360 ลิตร ได้โปรตีนเพียง 6–8 กรัมเท่านั้น พูดง่ายๆคือ เมื่อเทียบอัตราส่วนเป็นลิตรต่อกรัมโปรตีนแล้วนั้น วัวใช้น้ำ 60 ลิตรต่อกรัมโปรตีน / อโวคาโด ใช้น้ำ 194 ลิตรต่อกรัมโปรตีน แถมการเลี้ยงวัวในระบบธรรมชาติ (เช่น pasture-raised หรือ regenerative farming) ยังสามารถเป็นส่วนหนึ่งของระบบหมุนเวียนน้ำและคาร์บอนได้ พอเห็นภาพแล้วใช่ไหมครับ ดังนั้นเราควรระมัดระวังการเสพสื่อเอาไว้ด้วยว่า คำว่า "ดีต่อโลก" ไม่ได้หมายถึงพืชอย่างเดียว ทุกธุรกิจถ้าทำแบบที่ควรทำ มันยังสามารถผลักดันโลกไม่ให้ตกอยู่ในมือองค์กร future food ได้ เพราะมูลค่ามันสูงมาก
และเมื่อราคาสูง พื้นที่เพาะปลูกก็ขยายอย่างไร้การควบคุม ป่าธรรมชาติในรัฐมิโชอากังถูกแอบโค่นแบบผิดกฎหมายเพื่อแปลงสภาพเป็นไร่ “ทองเขียว” ข้อมูลจาก Reuters พบว่าผลไม้ที่ถูกส่งออกไปยังสหรัฐฯ บางส่วนมาจากแปลงปลูกที่บุกรุกป่าคุ้มครอง และรัฐบาลเองก็ไม่สามารถควบคุมได้เพราะอิทธิพลของกลุ่มทุนและมาเฟีย
ในโดมินิกันก็เช่นกัน มีรายงานจากสำนักข่าว Gestalten ว่าพื้นที่ป่าสงวนหลายพันไร่ถูกเปลี่ยนเป็นไร่อโวคาโด เพื่อป้อนตลาดผู้บริโภคในอเมริกาและยุโรปโดยตรง โดยไม่มีการชดเชยใดๆ แก่ชุมชนท้องถิ่น
สุขภาพที่ดีไม่ควรได้มาจากการทำลายสุขภาพของคนอื่น ไม่ควรมีผลไม้ใดที่ดูดีในจานของเรา แล้วเบื้องหลังเต็มไปด้วยคราบเลือดและน้ำตาของคนปลูก
เฮียไม่ได้จะบอกให้เลิกกินอโวคาโดเลย แต่เฮียอยากให้เรารู้ทัน ว่าความนิยมของอาหารสุขภาพวันนี้ กำลังเป็นสนามใหม่ของกลุ่มทุนโลก ที่พร้อมจะครอบครองด้วย “อำนาจอ่อน” ผ่านแบรนด์อาหารธรรมชาติ ผ่านกฎหมายสิ่งแวดล้อม หรือแม้แต่การครอบงำตลาดเสรีด้วยกำลังอาวุธ
นี่ไม่ใช่เรื่องไกลตัว เพราะเมื่อกลุ่มทุนเริ่มฮุบเมล็ดพันธุ์ คุมเส้นทางขนส่ง คุมฉลาก Certified Organic ทั้งหลาย พวกเขาก็ “ควบคุมสุขภาพ” ของผู้บริโภคเมืองอย่างเราไปด้วยโดยอ้อม
คำถามสำคัญที่มาทุกครั้งเวลามีเนื้อหาอะไรมาฝากคือ แล้วเราจะทำอะไรได้? 555555 - เลือกบริโภคผลไม้จากแหล่งที่โปร่งใสหรือปลูกเองได้ - สนับสนุนเกษตรกรรายย่อยที่ไม่อยู่ภายใต้กลุ่มทุน - ใช้เสียงของผู้บริโภคกดดันให้มีระบบตรวจสอบต้นทางจริง ไม่ใช่แค่ฉลากเขียวสวยๆ - และที่สำคัญ อย่าเชื่อว่า “ทุกสิ่งที่เขาวางให้ดูสุขภาพดี” จะดีจริง (ข้อนี่ละตัวดีเลยครับ)
สุขภาพไม่ใช่สินค้า และอาหารไม่ควรเป็นอาวุธของกลุ่มทุน หากเราเริ่มตระหนักว่าอาหารคือการเมือง น้ำคืออำนาจ และแปลงเกษตรคือสนามรบ เฮียเชื่อว่าผู้บริโภคอย่างเราจะไม่ยอมเป็นหมากอีกต่อไป #pirateketo #กูต้องรู้มั๊ย #ม้วนหางสิลูก #siamstr

2025-05-21 16:58:36The other day, I had the privilege of sitting down with one of my favorite living artists. Our conversation was so captivating that I felt compelled to share it. I’m leaving his name out for privacy.
Since our last meeting, I’d watched a documentary about his life, one he’d helped create. I told him how much I admired his openness in it. There’s something strange about knowing intimate details of someone’s life when they know so little about yours—it’s almost like I knew him too well for the kind of relationship we have.
He paused, then said quietly, with a shy grin, that watching the documentary made him realize how “odd and eccentric” he is. I laughed and told him he’s probably the sanest person I know. Because he’s lived fully, chasing love, passion, and purpose with hardly any regrets. He’s truly lived.
Today, I turn 44, and I’ll admit I’m a bit eccentric myself. I think I came into the world this way. I’ve made mistakes along the way, but I carry few regrets. Every misstep taught me something. And as I age, I’m not interested in blending in with the world—I’ll probably just lean further into my own brand of “weird.” I want to live life to the brim. The older I get, the more I see that the “normal” folks often seem less grounded than the eccentric artists who dare to live boldly. Life’s too short to just exist, actually live.
I’m not saying to be strange just for the sake of it. But I’ve seen what the crowd celebrates, and I’m not impressed. Forge your own path, even if it feels lonely or unpopular at times.
It’s easy to scroll through the news and feel discouraged. But actually, this is one of the most incredible times to be alive! I wake up every day grateful to be here, now. The future is bursting with possibility—I can feel it.
So, to my fellow weirdos on nostr: stay bold. Keep dreaming, keep pushing, no matter what’s trending. Stay wild enough to believe in a free internet for all. Freedom is radical—hold it tight. Live with the soul of an artist and the grit of a fighter. Thanks for inspiring me and so many others to keep hoping. Thank you all for making the last year of my life so special.

2024-12-02 10:44:07Bitcoin and Fixed Income was Written By Wyatt O’Rourke. If you enjoyed this article then support his writing, directly, by donating to his lightning wallet: ultrahusky3@primal.net
Fiduciary duty is the obligation to act in the client’s best interests at all times, prioritizing their needs above the advisor’s own, ensuring honesty, transparency, and avoiding conflicts of interest in all recommendations and actions.
This is something all advisors in the BFAN take very seriously; after all, we are legally required to do so. For the average advisor this is a fairly easy box to check. All you essentially have to do is have someone take a 5-minute risk assessment, fill out an investment policy statement, and then throw them in the proverbial 60/40 portfolio. You have thousands of investment options to choose from and you can reasonably explain how your client is theoretically insulated from any move in the \~markets\~. From the traditional financial advisor perspective, you could justify nearly anything by putting a client into this type of portfolio. All your bases were pretty much covered from return profile, regulatory, compliance, investment options, etc. It was just too easy. It became the household standard and now a meme.
As almost every real bitcoiner knows, the 60/40 portfolio is moving into psyop territory, and many financial advisors get clowned on for defending this relic on bitcoin twitter. I’m going to specifically poke fun at the ‘40’ part of this portfolio.
The ‘40’ represents fixed income, defined as…
An investment type that provides regular, set interest payments, such as bonds or treasury securities, and returns the principal at maturity. It’s generally considered a lower-risk asset class, used to generate stable income and preserve capital.
Historically, this part of the portfolio was meant to weather the volatility in the equity markets and represent the “safe” investments. Typically, some sort of bond.
First and foremost, the fixed income section is most commonly constructed with U.S. Debt. There are a couple main reasons for this. Most financial professionals believe the same fairy tale that U.S. Debt is “risk free” (lol). U.S. debt is also one of the largest and most liquid assets in the market which comes with a lot of benefits.
There are many brilliant bitcoiners in finance and economics that have sounded the alarm on the U.S. debt ticking time bomb. I highly recommend readers explore the work of Greg Foss, Lawrence Lepard, Lyn Alden, and Saifedean Ammous. My very high-level recap of their analysis:
-
A bond is a contract in which Party A (the borrower) agrees to repay Party B (the lender) their principal plus interest over time.
-
The U.S. government issues bonds (Treasury securities) to finance its operations after tax revenues have been exhausted.
-
These are traditionally viewed as “risk-free” due to the government’s historical reliability in repaying its debts and the strength of the U.S. economy
-
U.S. bonds are seen as safe because the government has control over the dollar (world reserve asset) and, until recently (20 some odd years), enjoyed broad confidence that it would always honor its debts.
-
This perception has contributed to high global demand for U.S. debt but, that is quickly deteriorating.
-
The current debt situation raises concerns about sustainability.
-
The U.S. has substantial obligations, and without sufficient productivity growth, increasing debt may lead to a cycle where borrowing to cover interest leads to more debt.
-
This could result in more reliance on money creation (printing), which can drive inflation and further debt burdens.
In the words of Lyn Alden “Nothing stops this train”
Those obligations are what makes up the 40% of most the fixed income in your portfolio. So essentially you are giving money to one of the worst capital allocators in the world (U.S. Gov’t) and getting paid back with printed money.
As someone who takes their fiduciary responsibility seriously and understands the debt situation we just reviewed, I think it’s borderline negligent to put someone into a classic 60% (equities) / 40% (fixed income) portfolio without serious scrutiny of the client’s financial situation and options available to them. I certainly have my qualms with equities at times, but overall, they are more palatable than the fixed income portion of the portfolio. I don’t like it either, but the money is broken and the unit of account for nearly every equity or fixed income instrument (USD) is fraudulent. It’s a paper mache fade that is quite literally propped up by the money printer.
To briefly be as most charitable as I can – It wasn’t always this way. The U.S. Dollar used to be sound money, we used to have government surplus instead of mathematically certain deficits, The U.S. Federal Government didn’t used to have a money printing addiction, and pre-bitcoin the 60/40 portfolio used to be a quality portfolio management strategy. Those times are gone.
Now the fun part. How does bitcoin fix this?
Bitcoin fixes this indirectly. Understanding investment criteria changes via risk tolerance, age, goals, etc. A client may still have a need for “fixed income” in the most literal definition – Low risk yield. Now you may be thinking that yield is a bad word in bitcoin land, you’re not wrong, so stay with me. Perpetual motion machine crypto yield is fake and largely where many crypto scams originate. However, that doesn’t mean yield in the classic finance sense does not exist in bitcoin, it very literally does. Fortunately for us bitcoiners there are many other smart, driven, and enterprising bitcoiners that understand this problem and are doing something to address it. These individuals are pioneering new possibilities in bitcoin and finance, specifically when it comes to fixed income.
Here are some new developments –
Private Credit Funds – The Build Asset Management Secured Income Fund I is a private credit fund created by Build Asset Management. This fund primarily invests in bitcoin-backed, collateralized business loans originated by Unchained, with a secured structure involving a multi-signature, over-collateralized setup for risk management. Unchained originates loans and sells them to Build, which pools them into the fund, enabling investors to share in the interest income.
Dynamics
- Loan Terms: Unchained issues loans at interest rates around 14%, secured with a 2/3 multi-signature vault backed by a 40% loan-to-value (LTV) ratio.
- Fund Mechanics: Build buys these loans from Unchained, thus providing liquidity to Unchained for further loan originations, while Build manages interest payments to investors in the fund.
Pros
- The fund offers a unique way to earn income via bitcoin-collateralized debt, with protection against rehypothecation and strong security measures, making it attractive for investors seeking exposure to fixed income with bitcoin.
Cons
- The fund is only available to accredited investors, which is a regulatory standard for private credit funds like this.
Corporate Bonds – MicroStrategy Inc. (MSTR), a business intelligence company, has leveraged its corporate structure to issue bonds specifically to acquire bitcoin as a reserve asset. This approach allows investors to indirectly gain exposure to bitcoin’s potential upside while receiving interest payments on their bond investments. Some other publicly traded companies have also adopted this strategy, but for the sake of this article we will focus on MSTR as they are the biggest and most vocal issuer.
Dynamics
-
Issuance: MicroStrategy has issued senior secured notes in multiple offerings, with terms allowing the company to use the proceeds to purchase bitcoin.
-
Interest Rates: The bonds typically carry high-yield interest rates, averaging around 6-8% APR, depending on the specific issuance and market conditions at the time of issuance.
-
Maturity: The bonds have varying maturities, with most structured for multi-year terms, offering investors medium-term exposure to bitcoin’s value trajectory through MicroStrategy’s holdings.
Pros
-
Indirect Bitcoin exposure with income provides a unique opportunity for investors seeking income from bitcoin-backed debt.
-
Bonds issued by MicroStrategy offer relatively high interest rates, appealing for fixed-income investors attracted to the higher risk/reward scenarios.
Cons
-
There are credit risks tied to MicroStrategy’s financial health and bitcoin’s performance. A significant drop in bitcoin prices could strain the company’s ability to service debt, increasing credit risk.
-
Availability: These bonds are primarily accessible to institutional investors and accredited investors, limiting availability for retail investors.
Interest Payable in Bitcoin – River has introduced an innovative product, bitcoin Interest on Cash, allowing clients to earn interest on their U.S. dollar deposits, with the interest paid in bitcoin.
Dynamics
-
Interest Payment: Clients earn an annual interest rate of 3.8% on their cash deposits. The accrued interest is converted to Bitcoin daily and paid out monthly, enabling clients to accumulate Bitcoin over time.
-
Security and Accessibility: Cash deposits are insured up to $250,000 through River’s banking partner, Lead Bank, a member of the FDIC. All Bitcoin holdings are maintained in full reserve custody, ensuring that client assets are not lent or leveraged.
Pros
-
There are no hidden fees or minimum balance requirements, and clients can withdraw their cash at any time.
-
The 3.8% interest rate provides a predictable income stream, akin to traditional fixed-income investments.
Cons
-
While the interest rate is fixed, the value of the Bitcoin received as interest can fluctuate, introducing potential variability in the investment’s overall return.
-
Interest rate payments are on the lower side
Admittedly, this is a very small list, however, these types of investments are growing more numerous and meaningful. The reality is the existing options aren’t numerous enough to service every client that has a need for fixed income exposure. I challenge advisors to explore innovative options for fixed income exposure outside of sovereign debt, as that is most certainly a road to nowhere. It is my wholehearted belief and call to action that we need more options to help clients across the risk and capital allocation spectrum access a sound money standard.

2025-05-23 07:35:13แหม่ ต้องรีบแวะมาเขียนไว้ก่อน ของกำลังร้อนๆ #ตัวหนังสือมีเสียง เพลง ลานกรองมันส์ นั้นเรื่องที่มาที่ไปน่าจะไปตามอ่านในเพจ ลานกรองมันส์ ได้ครับ recap คร่าวๆคือมันคือ พื้นที่สร้างสรรค์ที่เปิดให้มาทำกิจกรรมต่างๆนานากันได้ครับ
วันนี้เลยจะมาเล่าเรื่องวิธีการใช้คำ ซึ่งมันส์ดีตามชื่อลาน ฮาๆๆๆ ผมตั้งโจทย์ไว้เลยว่า ต้องมีคำว่า ลานกรองมันส์ แน่ๆแล้ว เพราะเป็นชื่อสถานที่ จากนั้นก็เอาคำว่า ลานกองมัน มาแตกขยายความเพราะมันคือต้นกำเนิดเดิมของพื้นที่นั้น คือเป็นลานที่เอาหัวมันมากองกันเอาไว้ รอนำไปผลิตต่อเป็นสินค้าการเกษตรต่างๆ
ตอนนี้เขาเลิกทำไปแล้ว จึงกลายมาเป็น ลานกรองมันส์ ที่เอาชื่อเดิมมาแปลง
เมื่อได้คำหลักๆแล้วผมก็เอาพยัญชนะเลย ลอลิง กอไก่ มอม้า คือตัวหลักของเพลง
โทนดนตรีไม่ต้องเลือกเลยหนีไม่พ้นสามช่าแน่นอน โทนมันมาตั้งแต่เริ่มคิดจะเขียนเลยครับ ฮาๆๆๆ
ผมพยายามแบ่งวรรคไว้ชัดๆ เผื่อไว้เลยว่าอนาคตอาจมีการทำดนตรีแบบแบ่งกันร้อง วรรคของมันเลยเป็น หมู่ เดี่ยว หมู่ เดี่ยว หมู่ เดี่ยว หมู่ แบบสามโทนเลย
ท่อนหมู่นั้น คิดแบบหลายชั้นมากครับ โดยเฉพาะคำว่า มัน เอามันมากอง มันที่ว่าได้ทั้งเป็นคำกิริยา คือ เอามันมากองๆ หรือ มันที่ว่าอาจหมายถึงตัวความฝันเองเป็นคำลักษณะนามเรียกความฝัน "ลานกรองมันส์ เรามาลองกัน มาร่วมกันมอง ลานกรองมันส์ มาร่วมสร้างฝัน เอามันมากอง"
หรือแม้แต่ท่อนต่างๆ ก็เล่นคำว่า มัน กอง เพื่อให้รู้สึกย้ำท่อนหมู่ ที่มีคำว่ามัน เป็นพระเอกหลายหน้า ทั้งความสนุก ทั้งลักษณะนามความฝัน ทั้งกิริยา "ทุกคน ต่างมี ความฝัน เอามา รวมกัน ให้มันเป็นกอง"
อีกท่อนที่ชอบมากตอนเขียนคือ ทำที่ ลานกรองมันส์ idea for fun everyone can do เพราะรู้สึกว่า การพูดภาษาอังกฤษสำเนียงไทยๆ มันตูดหมึกดี ฮาๆๆๆๆ
หัวใจของเพลงคือจะบอกว่า ใครมีฝันก็มาเลย มาทำฝันกัน เรามีที่ให้คุณ ไม่ต้องกลัวอะไรที่จะทำฝันของตัวเอง เล็กใหญ่ ผิดถูก ขอให้ทำมัน อย่าให้ใครหยุดฝันของคุณ นอกจากตัวคุณเอง
เพลงนี้ไม่ได้ลงแพลทฟอร์ม เพราะส่งมอบให้ทาง ลานกรองมันส์เขาครับ ใช้ตามอิสระไปเลย ดังนั้นก็อาจต้องฟังในโพสนี้ หรือ ในยูทูปนะครับ https://youtu.be/W-1OH3YldtM?si=36dFbHgKjiI_9DI8

2025-05-27 05:01:34There must be a limit to how much data is transferred across the bitcoin network in order to keep the ability to run and use your own node accessible. A node is required to interact with the global bitcoin network - if you do not use your own node then you must trust someone else's node. If nodes become inaccessible to run then the network will centralize around the remaining entities that operate them - threatening the censorship resistance at the core of bitcoin's value prop. The bitcoin protocol uses three main mechanisms to keep node operation costs low - a fixed limit on the amount of data in each block, an automatic difficulty adjustment that regulates how many blocks are produced based on current mining hash rate, and a robust dynamic transaction fee market.
Bitcoin transaction fees limit network abuse by making usage expensive. There is a cost to every transaction, set by a dynamic free market based on demand for scarce block space. It is an incredibly robust way to prevent spam without relying on centralized entities that can be corrupted or pressured.
After the 2017 bitcoin fee spike we had six years of relative quiet to build tools that would be robust in a sustained high fee market. Fortunately our tools are significantly better now but many still need improvement. Most of the pain points we see today will be mitigated.
The reality is we were never going to be fully prepared - pressure is needed to show the pain points and provide strong incentives to mitigate them.
It will be incredibly interesting to watch how projects adapt under pressure. Optimistic we see great innovation here.

2025-05-23 01:57:14น้ำนมมนุษย์ที่ไม่ง้อมนุษย์ หรือนี่กำลังจะกลายเป็นเรื่องจริงเร็วกว่าที่เราคิดนะครับ
ในยุคที่อุตสาหกรรมอาหารหันหลังให้กับปศุสัตว์ ไม่ว่าจะด้วยเหตุผลด้านสิ่งแวดล้อม จริยธรรม หรือความยั่งยืน “น้ำนมจากห้องแล็บ” กำลังกลายเป็นแนวหน้าของการปฏิวัติอาหาร โดยเฉพาะเมื่อบริษัทหนึ่งจากสิงคโปร์นามว่า TurtleTree ประกาศอย่างชัดเจนว่า พวกเขากำลังจะสร้างโปรตีนสำคัญในน้ำนมมนุษย์ โดยไม่ต้องมีมนุษย์แม่เลยแม้แต่น้อย
TurtleTree ก่อตั้งในปี 2019 โดยมีเป้าหมายอันทะเยอทะยานคือการผลิตโปรตีนในนมแม่ให้ได้ผ่านเทคโนโลยีที่เรียกว่า precision fermentation โดยใช้จุลินทรีย์ที่ถูกดัดแปลงพันธุกรรมให้ผลิตโปรตีนเฉพาะ เช่น lactoferrin และ human milk oligosaccharides (HMOs) ซึ่งเป็นองค์ประกอบล้ำค่าที่พบในน้ำนมมนุษย์แต่แทบไม่มีในนมวัว หรือผลิตภัณฑ์นมทั่วไป
โปรตีนตัวแรกที่ TurtleTree ประสบความสำเร็จในการผลิตคือ LF+ หรือ lactoferrin ที่เลียนแบบโปรตีนในนมแม่ ซึ่งมีหน้าที่ช่วยระบบภูมิคุ้มกันของทารก ต่อต้านแบคทีเรีย และช่วยให้ร่างกายดูดซึมธาตุเหล็กได้ดีขึ้น โปรตีนนี้เป็นหนึ่งในหัวใจของนมแม่ ที่บริษัทต้องการนำมาใช้ในอุตสาหกรรมนมผงเด็กและอาหารเสริมสำหรับผู้ใหญ่ ล่าสุดในปี 2024 LF+ ได้รับการรับรองสถานะ GRAS (Generally Recognized As Safe) จากองค์การอาหารและยาสหรัฐฯ (FDA) อย่างเป็นทางการ เป็นหมุดหมายสำคัญที่บอกว่า นี่ไม่ใช่แค่ไอเดียในแล็บอีกต่อไป แต่กำลังกลายเป็นผลิตภัณฑ์เชิงพาณิชย์จริง
เบื้องหลังของโปรเจกต์นี้คือการลงทุนกว่า 30 ล้านดอลลาร์สหรัฐจากกลุ่มทุนทั่วโลก รวมถึงบริษัท Solar Biotech ที่จับมือกับ TurtleTree ในการขยายกำลังการผลิตเชิงอุตสาหกรรมในสหรัฐอเมริกา โดยตั้งเป้าว่าจะสามารถผลิตโปรตีนเหล่านี้ได้ในระดับราคาที่แข่งขันได้ภายในไม่กี่ปีข้างหน้า
สิ่งที่น่าสนใจคือ TurtleTree ไม่ได้หยุดแค่ lactoferrin พวกเขายังวางแผนพัฒนา HMO ซึ่งเป็นน้ำตาลเชิงซ้อนชนิดพิเศษที่มีอยู่เฉพาะในน้ำนมแม่ เป็นอาหารเลี้ยงแบคทีเรียดีในลำไส้ทารก ช่วยพัฒนาระบบภูมิคุ้มกันและสมอง ปัจจุบัน HMOs เริ่มเป็นที่นิยมในวงการ infant formula แต่การผลิตยังจำกัดและมีต้นทุนสูง การที่ TurtleTree จะนำเทคโนโลยี precision fermentation มาใช้ผลิต HMO จึงถือเป็นความพยายามในการลดช่องว่างระหว่าง "นมแม่จริง" กับ "นมผงสังเคราะห์"
ทั้งหมดนี้เกิดขึ้นภายใต้แนวคิดใหม่ของอุตสาหกรรมอาหารที่เรียกว่า "functional nutrition" หรือโภชนาการที่ออกแบบเพื่อทำงานเฉพาะทาง ไม่ใช่แค่ให้พลังงานหรือโปรตีน แต่เล็งเป้าหมายเฉพาะ เช่น เสริมภูมิคุ้มกัน ซ่อมแซมสมอง หรือฟื้นฟูร่างกาย โดยมีรากฐานจากธรรมชาติ แต่ใช้เทคโนโลยีสมัยใหม่ในการผลิต
แม้จะฟังดูเป็นความก้าวหน้าทางวิทยาศาสตร์ที่น่าตื่นเต้น แต่น้ำเสียงที่ดังก้องในอีกมุมหนึ่งก็คือคำถามเชิงจริยธรรม TurtleTree กำลังสร้างโปรตีนที่มีอยู่เฉพาะในมนุษย์ โดยอาศัยข้อมูลพันธุกรรมของมนุษย์เอง แล้วนำเข้าสู่ระบบอุตสาหกรรมเพื่อการค้า คำถามคือ เมื่อใดที่การจำลองธรรมชาติจะกลายเป็นการผูกขาดธรรมชาติ? ใครควรเป็นเจ้าของข้อมูลพันธุกรรมของมนุษย์? และถ้าวันหนึ่งบริษัทใดบริษัทหนึ่งสามารถควบคุมการผลิต “นมแม่จำลอง” ได้แต่เพียงผู้เดียว นั่นจะส่งผลต่อเสรีภาพของสังคมในมุมไหนบ้าง?
นักชีวจริยธรรมหลายคน เช่น ดร.ซิลเวีย แคมโปเรซี จาก King's College London ตั้งข้อสังเกตไว้ว่า เทคโนโลยีแบบนี้อาจแก้ปัญหาการเข้าถึงนมแม่ในพื้นที่ห่างไกลหรือในกลุ่มแม่ที่ให้นมไม่ได้ แต่ขณะเดียวกันก็อาจกลายเป็นการสร้าง "ระบบอาหารทางเลือก" ที่ควบคุมโดยบริษัทไม่กี่ราย ที่มีอำนาจเกินกว่าผู้บริโภคจะตรวจสอบได้
เมื่อเทคโนโลยีสามารถจำลองสิ่งที่เคยสงวนไว้เฉพาะธรรมชาติ และมนุษย์ได้ใกล้เคียงจนแทบแยกไม่ออก บางทีคำถามที่ควรถามอาจไม่ใช่แค่ว่า “มันปลอดภัยหรือไม่?” แต่อาจต้องถามว่า “เราไว้ใจใครให้สร้างสิ่งนี้แทนธรรมชาติ?” เพราะน้ำนมแม่เคยเป็นสิ่งที่มาจากรักและชีวิต แต่วันนี้มันอาจกลายเป็นเพียงสิ่งที่มาจากห้องแล็บและโมเลกุล... และนั่นคือสิ่งที่เราต้องคิดให้เป็น ก่อนจะกินให้ดี เต่านี้มีบุญคุณอันใหญ่หลวงงงงงงง
เสริมจุดน่าสนใจให้ครับ KBW Ventures ถือเป็นผู้ลงทุนรายใหญ่ที่สุดใน TurtleTree Labs โดยมีบทบาทสำคัญในหลายรอบการระดมทุนของบริษัท KBW Ventures เป็นบริษัทลงทุนจากสหรัฐอาหรับเอมิเรตส์ ก่อตั้งโดย สมเด็จพระราชโอรสเจ้าชายคาเล็ด บิน อัลวาลีด บิน ตาลาล อัล ซาอุด (HRH Prince Khaled bin Alwaleed bin Talal Al Saud) ในรอบการระดมทุน Pre-A มูลค่า 6.2 ล้านดอลลาร์สหรัฐฯ ซึ่งปิดในเดือนธันวาคม 2020 KBW Ventures ได้ร่วมลงทุนพร้อมกับ Green Monday Ventures, Eat Beyond Global และ Verso Capital . นอกจากนี้ เจ้าชาย Khaled ยังได้เข้าร่วมเป็นที่ปรึกษาให้กับ TurtleTree Labs เพื่อสนับสนุนการขยายตลาดและกลยุทธ์การเติบโตของบริษัท
ซึ่งในตัว KBW Ventures นั้น เป็นบริษัทลงทุนที่มุ่งเน้นการสนับสนุนเทคโนโลยีที่ยั่งยืนและนวัตกรรมในหลากหลายอุตสาหกรรม เช่น เทคโนโลยีชีวภาพ (biotech), เทคโนโลยีพลังงานสะอาด, เทคโนโลยีการเงิน (fintech), เทคโนโลยีการขนส่ง, และเทคโนโลยีอาหาร (food tech) โดยเฉพาะ และในส่วนของเจ้าชาย Khaled มีความสนใจอย่างลึกซึ้งในด้านเทคโนโลยีอาหาร โดยเฉพาะในกลุ่มโปรตีนทางเลือก เช่น Beyond Meat ซึ่งเป็นการลงทุนที่สะท้อนถึงความมุ่งมั่นชัดเจนในการส่งเสริมอาหารที่ยั่งยืนและมีจริยธรรมครับ และแน่นอนเลยว่า โดยมีส่วนร่วมในรอบระดมทุนหลายครั้งของ Beyond Meat รวมถึงตอนที่ Beyond Meat เข้าตลาดหุ้น Nasdaq ครั้งแรกในปี 2019
เจ้าชาย Khaled เชื่อมั่นว่าอาหารทางเลือกแบบพืชจะถูกลงและแพร่หลายมากขึ้น จนอาจถูกกว่าราคาเนื้อสัตว์จากสัตว์จริงภายในปี 2025 ตามข้อมูลที่ได้มาแสดงว่า ปีนี้นี่หว่าาาาาาาาาา

2024-11-29 12:11:05In June 2023, the Law Commission of England and Wales published its final report on digital assets, concluding that the existing common law is generally flexible enough to accommodate digital assets, including crypto-tokens and non-fungible tokens (NFTs).
However, to address specific areas of uncertainty, the Commission recommended targeted statutory reforms and the establishment of an expert panel.
Key Conclusions and Recommendations:
1. Recognition of a Third Category of Personal Property:
Traditional English law classifies personal property into two categories: “things in possession” (tangible items) and “things in action” (enforceable rights). Digital assets do not fit neatly into either category. The Commission recommended legislation to confirm the existence of a distinct third category of personal property to better accommodate digital assets. 
-
Development of Common Law: The Commission emphasized that the common law is well-suited to adapt to the complexities of emerging technologies and should continue to evolve to address issues related to digital assets. 
-
Establishment of an Expert Panel: To assist courts in navigating the technical and legal challenges posed by digital assets, the Commission recommended that the government create a panel of industry experts, legal practitioners, academics, and judges. This panel would provide non-binding guidance on issues such as control and transfer of digital assets. 
-
Facilitation of Crypto-Token and Crypto-Asset Collateral Arrangements: The Commission proposed the creation of a bespoke statutory legal framework to facilitate the use of digital assets as collateral, addressing current legal uncertainties in this area. 
-
Clarification of the Financial Collateral Arrangements Regulations: The report recommended statutory amendments to clarify the extent to which digital assets fall within the scope of the Financial Collateral Arrangements (No 2) Regulations 2003, ensuring that existing financial regulations appropriately cover digital assets. 
Overall, the Law Commission’s report underscores the adaptability of English common law in addressing the challenges posed by digital assets, while also identifying specific areas where legislative action is necessary to provide clarity and support the evolving digital economy.

2024-05-21 12:38:08Bitcoin transactions explained
A transaction is a piece of data that takes inputs and produces outputs. Forget about the blockchain thing, Bitcoin is actually just a big tree of transactions. The blockchain is just a way to keep transactions ordered.
Imagine you have 10 satoshis. That means you have them in an unspent transaction output (UTXO). You want to spend them, so you create a transaction. The transaction should reference unspent outputs as its inputs. Every transaction has an immutable id, so you use that id plus the index of the output (because transactions can have multiple outputs). Then you specify a script that unlocks that transaction and related signatures, then you specify outputs along with a script that locks these outputs.
As you can see, there's this lock/unlocking thing and there are inputs and outputs. Inputs must be unlocked by fulfilling the conditions specified by the person who created the transaction they're in. And outputs must be locked so anyone wanting to spend those outputs will need to unlock them.
For most of the cases locking and unlocking means specifying a public key whose controller (the person who has the corresponding private key) will be able to spend. Other fancy things are possible too, but we can ignore them for now.
Back to the 10 satoshis you want to spend. Since you've successfully referenced 10 satoshis and unlocked them, now you can specify the outputs (this is all done in a single step). You can specify one output of 10 satoshis, two of 5, one of 3 and one of 7, three of 3 and so on. The sum of outputs can't be more than 10. And if the sum of outputs is less than 10 the difference goes to fees. In the first days of Bitcoin you didn't need any fees, but now you do, otherwise your transaction won't be included in any block.
If you're still interested in transactions maybe you could take a look at this small chapter of that Andreas Antonopoulos book.

2024-03-23 08:57:08Nostr is not decentralized nor censorship-resistant
Peter Todd has been saying this for a long time and all the time I've been thinking he is misunderstanding everything, but I guess a more charitable interpretation is that he is right.
Nostr today is indeed centralized.
Yesterday I published two harmless notes with the exact same content at the same time. In two minutes the notes had a noticeable difference in responses:
The top one was published to
wss://nostr.wine
,wss://nos.lol
,wss://pyramid.fiatjaf.com
. The second was published to the relay where I generally publish all my notes to,wss://pyramid.fiatjaf.com
, and that is announced on my NIP-05 file and on my NIP-65 relay list.A few minutes later I published that screenshot again in two identical notes to the same sets of relays, asking if people understood the implications. The difference in quantity of responses can still be seen today:
These results are skewed now by the fact that the two notes got rebroadcasted to multiple relays after some time, but the fundamental point remains.
What happened was that a huge lot more of people saw the first note compared to the second, and if Nostr was really censorship-resistant that shouldn't have happened at all.
Some people implied in the comments, with an air of obviousness, that publishing the note to "more relays" should have predictably resulted in more replies, which, again, shouldn't be the case if Nostr is really censorship-resistant.
What happens is that most people who engaged with the note are following me, in the sense that they have instructed their clients to fetch my notes on their behalf and present them in the UI, and clients are failing to do that despite me making it clear in multiple ways that my notes are to be found on
wss://pyramid.fiatjaf.com
.If we were talking not about me, but about some public figure that was being censored by the State and got banned (or shadowbanned) by the 3 biggest public relays, the sad reality would be that the person would immediately get his reach reduced to ~10% of what they had before. This is not at all unlike what happened to dozens of personalities that were banned from the corporate social media platforms and then moved to other platforms -- how many of their original followers switched to these other platforms? Probably some small percentage close to 10%. In that sense Nostr today is similar to what we had before.
Peter Todd is right that if the way Nostr works is that you just subscribe to a small set of relays and expect to get everything from them then it tends to get very centralized very fast, and this is the reality today.
Peter Todd is wrong that Nostr is inherently centralized or that it needs a protocol change to become what it has always purported to be. He is in fact wrong today, because what is written above is not valid for all clients of today, and if we drive in the right direction we can successfully make Peter Todd be more and more wrong as time passes, instead of the contrary.

2024-03-19 14:32:01Censorship-resistant relay discovery in Nostr
In Nostr is not decentralized nor censorship-resistant I said Nostr is centralized. Peter Todd thinks it is centralized by design, but I disagree.
Nostr wasn't designed to be centralized. The idea was always that clients would follow people in the relays they decided to publish to, even if it was a single-user relay hosted in an island in the middle of the Pacific ocean.
But the Nostr explanations never had any guidance about how to do this, and the protocol itself never had any enforcement mechanisms for any of this (because it would be impossible).
My original idea was that clients would use some undefined combination of relay hints in reply tags and the (now defunct)
kind:2
relay-recommendation events plus some form of manual action ("it looks like Bob is publishing on relay X, do you want to follow him there?") to accomplish this. With the expectation that we would have a better idea of how to properly implement all this with more experience, Branle, my first working client didn't have any of that implemented, instead it used a stupid static list of relays with read/write toggle -- although it did publish relay hints and kept track of those internally and supportedkind:2
events, these things were not really useful.Gossip was the first client to implement a truly censorship-resistant relay discovery mechanism that used NIP-05 hints (originally proposed by Mike Dilger) relay hints and
kind:3
relay lists, and then with the simple insight of NIP-65 that got much better. After seeing it in more concrete terms, it became simpler to reason about it and the approach got popularized as the "gossip model", then implemented in clients like Coracle and Snort.Today when people mention the "gossip model" (or "outbox model") they simply think about NIP-65 though. Which I think is ok, but too restrictive. I still think there is a place for the NIP-05 hints,
nprofile
andnevent
relay hints and specially relay hints in event tags. All these mechanisms are used together in ZBD Social, for example, but I believe also in the clients listed above.I don't think we should stop here, though. I think there are other ways, perhaps drastically different ways, to approach content propagation and relay discovery. I think manual action by users is underrated and could go a long way if presented in a nice UX (not conceived by people that think users are dumb animals), and who knows what. Reliance on third-parties, hardcoded values, social graph, and specially a mix of multiple approaches, is what Nostr needs to be censorship-resistant and what I hope to see in the future.
