Welcome to this year's first Kraków Bitcoin Meetup!

The time has been set, and we are fortunate to be hosted by our new sponsor Codete for this as well as future events.

This event will be a discussion about smart contracts on the Bitcoin blockchain, led by the charismatic "Bitcoin traveler" and twice former Bitcoin Meetup speaker Rafael Hauxley.

Rafael will be taking a general overview of smart contracts on blockchain - specifically if the Bitcoin blockchain can run smart contracts. Questions discussed will range from: What are smart contracts (a short overview), to, can a Bitcoin sidechain such as Rootstock (RSK) run smart contracts over the Bitcoin blockchain? Other discussions will take a look at major alternatives to ETH-based smart contracts, such as: WAX, NEO, Cardano, ETH Classic and others.

Rafael will conclude with a discussion on his startup: GoldPencil - inviting any and all comments, criticisms and general thoughts.


The Kraków Bitcoin Meetup is an initiative for Bitcoin enthusiasts in the city of Kraków, Poland, organized by BitSpace and sponsored by Codete. The event is held frequently and aims to connect the brightest local crypto minds together. It also aims to provide educational value through presentations and workshops for people who want to learn more about Bitcoin. Even though this event is primarily about Bitcoin, you are of course permitted to mention other cryptocurrencies :)

The events are free of charge, and there are no knowledge requirements for you to participate. Come and learn!

Please invite other people who might be interested in attending.


If you have something to share or announce with the meetup, give a heads up and the stage is yours. Anything that might be valuable for a local crowd of bitcoiners is very welcome.

Additionally, we're always looking for interesting speakers to talk at the meetups. If you or someone you know have/has insightful things to say on a Bitcoin-related topic, don't hesitate to discuss it with me, and we will schedule a talk.
