Vinteum BDL Mentor Spotlight: Matthew Zipkin ⚡
"It's a simulation of the Bitcoin Core development process but in a hackathon environment."
Matthew tells us about the "quorumeum" challenge he ran for students in the @vinteum_org and @libdesatoshi programs during BDL week. In the interview he shares what the role of a Bitcoin maintainer actually looks like, and how changes get merged into Bitcoin Core.
Matthew works on educational initiatives at @ChaincodeLabs, and is impressed by what he sees from the Latin American Bitcoin communities.

What's happening in #Cuba and how does #Bitcoin help?
¿Qué está pasando en Cuba y cómo ayuda Bitcoin?
Co-founders of Cuba Bitcoin (@Cuba_BTC), @Catry_a and @Forte11Cuba tell the story of the humanitarian crisis unfolding in Cuba before providing an overview of the work they've done in their home country, including working on @MostroP2P.
Cofundadores de Cuba Bitcoin, Catrya y Forte, cuentan la historia de la crisis humanitaria que se está desarrollando en Cuba, antes de ofrecer una visión general del trabajo que han realizado en su patria, incluyendo trabajando en Mostro.
And @ReynaChicas2 of @MyFirstBitcoin_ translates the conversation, making this the first time the story of Cuba Bitcoin has been told in English.
Y Reyna Chicas de Mi Primer Bitcoin traduce la conversación, lo que convierte a esta en la primera vez que se cuenta la historia de Cuba Bitcoin en inglés.
In the conversation, we discuss:
⚡️ The decades of dictatorship in Cuba
⚡️ If Cubans want U.S. intervention
⚡️ What Bitcoin does and doesn't fix
⚡️ The freedom tech Forte and Catrya have created
⚡️ What it's like to teach Bitcoin in Cuba
En la conversación, hablamos sobre:
⚡️ Las décadas de dictadura en Cuba
⚡️ Si los cubanos quieren la intervención de los EE.UU
⚡️ Lo que Bitcoin soluciona y lo que no
⚡️ La tecnología de la libertad que Forte y Catrya han creado
⚡️ Cómo es enseñar Bitcoin en Cuba
Forte and Catrya's story is a true testament to how Bitcoin represents the will of the people, and how people like them are the protagonists in the Bitcoin story who bring the technology to life and make it usable for everyday people.
La cuenta de Forte y Catrya es un verdadero testimonio de cómo Bitcoin representa la voluntad del pueblo y cómo personas como ellos son los protagonistas de la historia de Bitcoin, quienes dan vida a la tecnología y la hacen utilizable para la gente común.
Enjoy this very inspiring episode.
Disfruta de este episodio inspirador.

BEWARE TRAVELING TO 🇭🇰 HONG KONG WITH BITCOIN HARDWARE WALLETS
Hong Kong has updated enforcement rules under the National Security Law as of March 23, 2026.
Refusing to provide passwords or decryption assistance to police is now a criminal offense, covering ALL personal devices including phones, laptops, and likely hardware wallets.
The rule applies to everyone in Hong Kong, including US citizens, even if only transiting through the airport.
Authorities also have expanded powers to seize and retain devices they claim are linked to national security investigations.
Travelers are advised to understand the risks before entering or transiting through the region.

I don't think these @FoundryServices blocks were a selfish-mining "attack". While it might look similar, the data multiple parties have contributed points to "expected" network behavior. I've written a functional test to simulate this.
