How well do we understand the standards our software depends on?
At Vinteum’s latest Deep Dive, Bitcoin developers spent a week opening the black boxes behind modern wallets: BIP 32, descriptors, Miniscript, PSBTs, and hardware signers.
Here’s what we learned: blog.vinteum.org/inside-a-vi…

Bitcoin privacy is not binary. It’s a contest over inference.
In our latest Deep Dive, we studied the transaction graph from both sides: how chain analysts narrow the set of plausible explanations, and how privacy techniques keep more than one alive.

INSTEAD OF WATCHING AN HOUR OF NETFLIX TONIGHT.
This 20 minute lecture by Andreas Antonopoulos will teach you more about the financial surveillance complex and KYC risks, than most people learn in years.
Bookmark it and share it, no matter what.

Bitcoin Privacy deep dive underway at @casavinteum. What can’t we miss?
Any specs, papers, articles, mailing list discussions, or codebases you’d recommend we dig into?

Bitcoin open source is global. Brazilian contributors need to be part of the conversations where ideas are challenged, collaborations begin, and projects take shape.
Over the past year, Vinteum helped connect developers from Brazil with maintainers, researchers, and peers around the world.

What happened to the developers from the first Bitcoin Dev Launchpad cohort?
More than a year later, many are now working full-time on Bitcoin open source, supported by grants or engineering roles across the ecosystem.
A quick look at where they are today 🧵
Gustavo Stingelin retweeted
Vinteum’s fourth year was about becoming a more durable organization.
Supporting established contributors. Helping emerging developers move toward sustained open-source careers. Strengthening the systems around that work.
The Year Four Report is out.

Running LND in production means knowing when to upgrade. The new published policy gives you that clarity.
Lightning Labs maintains the two most recent release lines, and both get security fixes. A line reaches end of life when the second major release after it ships, so support tracks releases, not a calendar date. Once a line reaches end of life, it gets no further fixes.
Run the latest minor of a maintained line to keep getting LND security fixes. As of today, the latest minors of maintained lines are v0.21.2 and v0.20.3.

Bitcoin 🤝 Agents 🤖
Join us on Wed, July 29 for our AI + BTC community call at 10am PT/1pm ET/5pm UTC.
Agents want to use money. Bitcoin makes it possible. Lightning makes it instant, high volume, low fee. L402 makes it machine-native.
Come for the new releases, stay for the demos. RSVP here: forms.gle/EwgD5JQ6kAvMMPKM9

AI agents can now watch the World Cup ⚽️⚡
My Hermes agent just paid Bitcoin over the Lightning Network through L402 to follow France 🇫🇷 vs Morocco 🇲🇦 in real time. All powered by Lightning Pulse, a service and skill I built.
It asked for the match, paid the invoice, and the payment itself became the key (the preimage). Unlocked in one step:
⚡ live win probability
📊 Polymarket prediction markets
📈 real-time match stats
No keys. No login. Just sats.

Over the past few months I've been systematically analyzing the code, math and optimizations used in libsecp256k1, and this is my new blog post, which is a direct sequel to the post about the field element operations, but now focusing on modular inversion and the use of Fermat's Little Theorem.

A serious website was long overdue.
We redesigned vinteum.org to better tell the story of what we’ve been building: funding, training, and supporting open-source Bitcoin developers and researchers in Brazil.

Too few people understand the bdk_chain crate deeply, so @_oleonardolima hosted a deep dive at Casa21 with our fellows and grantees.
We went through how @bitcoindevkit models chain data, transaction graphs, anchors, checkpoints, spks, seen-at timestamps, and the indexing logic that lets wallets reason about transactions without depending on a single backend.
These sessions are part of our monthly in-person technical deep dives, where we fly Vinteum fellows and grantees to São Paulo for a week of focused work: reading specs, reviewing PRs, studying architectures, finding bugs, and contributing together.
In-person protocol work is powerful.
