Cardano founder Charles Hoskinson announces Midnight enters beta testing

Charles Hoskinson just pulled the curtain back on Midnight.city, the AI-driven interactive simulation platform built on the Midnight network, confirming it has officially entered beta testing. The Cardano founder and Input Output Global (IOG) chief said new features are being shipped on a two-week sprint cycle. For those keeping score, Midnight’s mainnet went live on March 30, 2026. Hoskinson has reportedly poured roughly $200M into the project. What Midnight.city actually does Midnight.city is a public-facing platform designed to stress-test the Midnight network by simulating realistic transaction loads at scale. AI agents perform transactions, test privacy features, and simulate the things that thousands of real users would do before thousands of real users actually show up. The core technology underneath is built around programmable privacy, a concept that lets developers choose exactly what information gets revealed and what stays hidden in any given transaction. The mechanism behind this is selective disclosure, powered by zero-knowledge proofs. In simpler terms, you can prove something is true without revealing the underlying data. This is a meaningful distinction from most p...
