Substrate Seminar

Biweekly conversations on the cutting-edge of blockchain

An Open Collaborative Learning Call

Substrate Seminar is a biweekly collaborative learning space, where we hear from developers and projects building on Substrate. Run by DevHub, we meet every other Tuesday at 14:00UTC.

Learn and Share

We begin by hearing from a member of the ecosystem and getting insights into what they're working on.

The second half of each seminar is open for Q & A like office hours, so bring your questions. Got code that doesn’t compile? Bring that along, too! Participants will be invited on-screen to share their work and their questions. You may also join us between seminars on Element.

The seminar is generally developer-oriented, but less technical participants and questions are also welcome. If your questions turn out to be off-topic, we'll point in the direction of the resources you need.

Upcoming Seminars

19 Oct

The Substrate new documentation hub is here and Parity’s Sacha Lansky and Lead Web Developer Imad Arain are super excited to present it to you. In this seminar, join us to learn about the improved UX features implemented to make Substrate docs easier to navigate and learn with. Learn how to navigate existing content efficiently and how to contribute new content following our contribution guidelines. Join and bring your questions to participate.

2 Nov

In this seminar, Parity Developer Advocate Sacha Lansky will walk through some of Substrate’s key concepts by diving into some intermediate level how-to guides. In doing so, he plans to showcase different implementations of certain concepts and their APIs, with a focus on how to write pallets that are customized for a particular use case. Topics will include: pallet coupling, origins and runtime configurations.

16 Nov

Alain a.k.a Brenzi, co-founder at Integritee will dive into ways to leverage off-chain capabilities as second-layer solutions for Substrate based chains. Topics will include off-chain workers and the benefits of sidechain architectures.

30 Nov

Michal Swietek, Co-founder of Aleph will be presenting Aleph: the first asynchronous Byzantine Fault Tolerant consensus protocol that achieves asymptotically optimal performance: constant latency and communication complexity. The goal of this talk is to give a bird’s eye view of Aleph, it’s implementation in Rust and our experience in integrating it as a finality gadget in Substrate (replacing GRANDPA with Aleph). The differences between Aleph and GRANDPA will be discussed, including performance benchmarks and some tradeoffs.
