GenLayer Labs – Barcelona (Hybrid)

About GenLayer Labs

GenLayer Labs is a decentralized AI research collective building the trust infrastructure for the AI Age. We are the developers of GenLayer—an open, AI-driven Court of the Internet—a synthetic jurisdiction where autonomous agents and protocols can reason, transact, and govern at machine speed with sovereignty, transparency, and trust. Our infrastructure enables autonomous agents and smart contracts to access live web data, interpret natural language, and resolve disputes using AI consensus.

Backed by Maelstrom (Arthur Hayes), Arrington Capital, and North Island Ventures, we’re defining a new category of decentralized infrastructure: trustless decision-making for the AI age.
