Lightning⚡ is best known as a network for fast bitcoin payments. But what if the same infrastructure could also carry private messages?

That’s the idea behind onion messages🧅. They rely on onion encryption, a technique where data is wrapped in multiple layers of encryption, like layers of an onion. As the message travels through the network, each node removes just one layer, learning only where the message came from and where it should go next. No single node ever sees the full route or the original sender and final recipient.

In this article, @Thevelopher explores how onion messages work, how they differ from traditional payment routing, and how they’re being implemented in LND. The piece also looks at why this small protocol change could turn Lightning into more than just a payment network.

🔥 Announcing the release of Polar v4.0.0! 🚀

You can now use your AI agents to control the nodes in your Lightning networks using the integrated MCP server.

Check out this Cursor agent confirming the balances displayed in my demo app are accurate.

We’re excited to have @Extheo, CEO and co‑founder of @mavapay, joining the #BtrustDeveloperDay lineup.🚀

Theo is a dedicated bitcoin advocate and builder working to expand bitcoin adoption and infrastructure across the African continent.

As CEO of Mavapay, he’s pioneering payment systems that connect African businesses to the global bitcoin economy.

An alumnus of the @btrust_builders program, Theo has led developer workshops and bootcamps across Nigeria 🇳🇬 and Ghana 🇬🇭, and remains deeply engaged in building open‑source tools that advance real‑world bitcoin use.

His focus on technical education in the Global South has inspired and trained a new generation of builders across the bitcoin ecosystem.

In the workshop, Theo, @Thevelopher and @SulaimanAminuB2 will walk participants through the practical process of deploying an LND node environment, and integrating it with NodeGaze, an open‑source observability tool for visualizing real‑time channel health, payments, and system events.

Theo will also be part of the Lightning Round Q&A, alongside other global contributors and African builders. This session gives you the chance to ask questions about contribution paths, opportunities and challenges, so come prepared with your questions.

LFG 🙌🏼

[Btrust @btrustteam]

We’re excited to have @Thevelopher, software engineer and Btrust grantee, speaking at the #BtrustDeveloperDay.

Abdullahi contributes to LND, one of the open‑source implementations of the Lightning Network, where his work focuses on implementing the onion message protocol, optimizing the network graph, and developing rigorous tests to enhance system stability.

At the Developer Day, Abdullahi will join @Extheo and @SulaimanAminuB2 for a hands-on workshop.

The workshop will guide participants through the process of setting up a Lightning node, configuring it for reliability, and maintaining privacy and stability through best practices.

Attendees will also learn how to automate key tasks to optimize performance and streamline operations, gaining practical insights into how professional developers manage Lightning nodes at scale.

We’re happy to have @pins_btc joining us as a speaker at the upcoming #BtrustDeveloperDay! ⚡

Pins is a @Vinteum_org grantee currently contributing to LND (Lightning Network Daemon).

His journey into Bitcoin development is a powerful example of passion meeting persistence. After starting his career as a software developer, Pins transitioned to commercial and sales roles in cybersecurity within major tech companies. Yet, his love for Bitcoin and open-source software reignited his drive to get back to hands-on coding.

Over the past two years, Pins has dedicated himself to relearning programming and has been actively contributing to the LND codebase.

At Developer Day, Pins will lead a hands-on workshop titled Taproot Lightning Channels from Scratch, designed for developers eager to dive deep into the Taproot transactions required to create and operate simple Taproot channels.

Don’t miss this opportunity to learn directly from Pins and strengthen your understanding of how Bitcoin’s latest protocol upgrades expand the possibilities of the Lightning Network.
