Building the Internet of Blockchains Since 2023

Building the Internet of Blockchains Since 2023

What if developers didn’t just build apps… but entire economies?

In Cosmos, that’s not a dream. It’s the design. The Cosmos Stack gave us the tools to build sovereign, interoperable chains. Where you define the rules, the architecture, and the purpose. Purpose-built Layer 1 blockchains are made in Cosmos. Hackmos is the hackathon that represents this vision, it is the home for developers that want to go beyond, that want to build the user-owned internet.
