Communities 🦻

  • Rust and Concordium

    As you know, we are building these days an ambitious but humble Dev Rel program that is mainly targeting Rust Developers.

    Based on the principle of reciprocity, the Dev X Initiative (this is the cute name of our Dev Rel program) is thought and designed in collaboration with the Rust community in the UK and with some Rust developers coming from the Rust in Crypto Working group.

    Stay tuned here, we will release asap the material.

    But meanwhile, some updates coming from the Rust Ecosystem:

    • Checkout the Rust Gamedev Podcast. This podcast covers in-depth interviews with indie game developers creating titles with the Rust programming language. They cover technical topics as well as the business of open source and commercial indie games development.

  • Encode Club Education Series

    We have launched together with our friends at Encode Club, an ambitious early-stage education program for students and young developers.

    The course will consist of two parts:

    • An ‘Intro to blockchain’ event to explain how the technology works, with a focus on Concordium’s offering

    • A ‘Learn to code in blockchain’ event, explaining how to use Concordium to build blockchain applications.

    For more information visit Encode.

  • Testnet 3 Rewards announcement

    We have completed reviews for people who submitted correctly in Github, but as promised we are making some exceptions, and we are starting to look at duplicates, closed pull requests, and feedback on pending items.

    We will announce when the period for feedback commences in the coming weeks with the first final results draft. You can check out the in-progress OT3 results calculation here.
