Experienced Bitcoin developers from Blockstream, Chaincode Labs, and many more will be sharing their knowledge through 25 minute talks and panel discussions. This is an opportunity to hear their thoughts, live, and ask them questions.


This is where you'll learn the most. Select which workshops you want to attend and spend a day learning from Bitcoin experts. Bring your laptop as these sessions are designed to get you building. At the last conference participants installed and configured Lightning nodes, built hardware wallets and Bitcoin node crawlers. For this conference expect even more workshops.


Meet the people that make Bitcoin happen! Share ideas, swap contact details, and make new friends/business connections. After the conference dinners, drinks, and social events will take place close to the venue.

Let’s take Bitcoin development to the next level.

Speakers will share with you what they've been working on and some of their lessons learnt. These talks will both inform and inspire you.
