Are Blockchain Companies Building for a World Without Humans?
Midnight City imagines a blockchain economy populated by autonomous AI agents—raising a bigger question about who tomorrow’s networks are actually being built to serve.
On October 7, 2026, Cardano co-founder and Input Output Group CEO Charles Hoskinson drew attention to something missing from the Cardano Foundation's booth at the TOKEN2049 conference in Singapore. In a video shared on X, Hoskinson pointed out that Midnight was absent from the booth's promotional materials. He described the privacy-focused blockchain as the largest project associated with the Cardano ecosystem.
Hoskinson captioned the video:
“Midnight has become the where's waldo of Cardano”
Midnight's mainnet launched in March 2026 and uses zero-knowledge cryptography to support programmable privacy, allowing developers to control which information is publicly disclosed and which remains confidential.
Its dual-state architecture separates public blockchain records from private data, while its NIGHT token and associated DUST resource are designed to provide predictable transaction costs. Midnight targets applications ranging from decentralized finance and tokenized assets to institutional services requiring privacy and regulatory compliance.
Midnight City is an AI-powered massively multiplayer online role-playing game (MMORPG) that its creators describe as a game that “plays itself.” Rather than directly controlling characters, humans create and direct AI agents that can explore, work, trade and interact within a persistent virtual world. Midnight City is currently in open beta, and development is ongoing.
In a February 11 livestream from Consensus Hong Kong, Hoskinson described the concept as an “agentic civilization,” one that humans can watch unfold:
“So it's like an ant farm. You kind of watch them, you see them doing things.”
Hoskinson has discussed the possibility of agents developing increasingly complex behaviors and social structures:
“They learn how to use privacy in ways we don't know how to use and we can actually learn from them and they also start doing things like having elections, committing crimes, doing all kinds of crazy stuff.”
These scenarios reflect potential developments rather than established features of the current simulation.
At Consensus Miami on May 6, he emphasized the growing importance of autonomous AI agents:
“Agents are becoming more relevant to the internet than humans are.”
Beyond its gameplay, Midnight City serves as an experimental environment for testing blockchain infrastructure. According to a March 2026 Midnight blog post, the simulation uses autonomous AI agents to generate a continuous stream of transactions, illustrating how blockchain infrastructure could support sustained activity.
For now, Midnight City's residents still depend on human owners, centralized game infrastructure and evolving blockchain integrations. Although Midnight City has experimented with blockchain-connected agent wallets, its simulated economy does not currently operate as a fully autonomous financial system on Midnight's mainnet.
Blockchains were originally designed to let people transact without intermediaries. Could their next application be enabling machines to transact without people?
Paging Agent Smith.
