This website is no longer maintained and no updates will be published in the future. I've made this decision because at this moment there are better alternatives, with more up to date information about these events.

Here are some places where you can find information about new hackathons:


Blockchain and dApp Challenges

This website aims to aggregate public information about open competitions and challenges related to blockchain technologies and smart-contract development.

Learning about these subjects can be hard, even after learning one approach, it might require extra motivation to explore all other competing technologies on other networks.

These kind of competitions provide guidance, prizes and "special attention" of development teams, making them a good incentive to learn and explore new things.

Finding about them and checking the ones more suited for your situation might might be a ton of work, that is why I created this page trying to aggregate the information in one place.


My name is Gonçalo Valério, currently I'm software developer with a certain interest in distributed systems and security.

I pretty much prefer decentralized and open systems, that rely on open standards favoring interoperability, than to support the so called "walled gardens".
