Sat down with @james_bachini at Stellar House CDMX for Dev Diaries.

Four Costa Ricans building ACTA: the identity & credentials layer @StellarOrg was missing.

Native Stellar DID.
Live on Mainnet.
Real clients already issuing.

190 builders showed up to Código Alebrije 🇲🇽

72 hours later, 47 projects live on Stellar

Real mentorship from the @StellarOrg team, real pressure and real support.

This is what breaking into the ecosystem looks like. 🚀

Excited to share that @ActaXyz was selected for the Scale Track at Código Alebrije CDMX 2026🇲🇽

From March 19–23, we’ll join builders across the region in a program focused on execution, mentorship, and scaling in the Stellar ecosystem.

Excited to build in CDMX🚀

Two tracks, 200+ builders, and a chance to get accelerated by @StellarOrg in just 3 weeks.

Finished Week 2 of Impacta Bootcamp: deployed my first Stellar smart contract, worked with XDR, and verified everything on-chain. Thanks @TheBAFNetwork and @TrustlessWork ready for Week 3! 🚀

Stellar just took an X-Ray 🩻

With Protocol 25 (X-Ray) now live on mainnet, Stellar delivers its most significant privacy upgrade to date.

Native ZK primitives are here: BN254 + Poseidon.
This isn’t a feature. It’s foundational infrastructure.

What this unlocks 🔓
• Efficient on-chain ZK proof verification
• Lower costs for ZK-based smart contracts
• Easier migration of existing ZK apps
• Real interoperability with the broader ZK ecosystem

Privacy on public blockchains no longer has to be all-or-nothing.

With X-Ray, Stellar enables configurable, verifiable, compliance-ready privacy.

👀 Especially relevant for identity, credentials, and any application where proving something without revealing everything makes the difference.

Building forward.

¿Cuál es la mejor blockchain (L2) para LATAM?

Esa fue la pregunta que me hice cuando empecé en web3.

Hice lo que toda persona del 2025 haría, abrí una IA buscando respuestas, hice un prompt para mejorar mi prompt y cuando era suficientemente bueno, empecé a analizar la respuesta, una lista de quince blockchains. Quince!

Sentí que eran demasiadas opciones para analizar, aparte, cómo iba a analizar algo que no conozco, zk-rollups, optimistic, EVM compatible, stage 1, son algunos de los términos que salían, me sentí saturado, cada vez con más preguntas que respuestas.

Con el paso de los meses, Scroll dejó de ser un nombre en una lista. Descubrí un programa que acompaña durante un año a quienes quieren pasar de builder a founder. Descubrí que están haciendo hackathons de contenido, los nodos locales y que tienen aplicaciones que puedes usar en tu día a día.

En otras palabras, tienen propuesta para builders, creadores y usuarios.

Hoy te cuento por qué le tengo cariño a @Scroll_ES : porque, entre tanto movimiento, he encontrado algo diferente.

En web3, donde todo se mueve tan rápido, la tecnología es importante, pero la comunidad pesa más que cualquier ranking.

[ACTA @ActaXyz]

¡Este martes nos vemos en el After Office – Stellar Edition! 🍻

Con @ActaXyz, @TheBAFNetwork , @StellarOrg apoyando a la comunidad Web3 🇨🇷
