Harmony Cites AI Threats in Proposed Blockchain Shutdown

In brief

• Harmony says threats from AI agents and state actors have become too great to keep its blockchain running.
• The team proposes moving ONE to Ethereum and redirecting token emissions toward AI video.
• The plan is non-binding, with users urged to exit smart contracts before September 10.

Harmony, once a prominent competitor to Ethereum, has proposed shutting down its blockchain on Sunday, saying threats from AI agents and state actors had become too great.

The announcement comes as the cryptocurrency industry attempts to defend against increasingly sophisticated cyberattacks enabled by frontier AI models, including Anthropic’s Claude Mythos and OpenAI’s GPT-6 Astra.

“The threats posed by state actors and AI agents are too great,” the Harmony Team wrote on X. “Since our mainnet launch in 2019, our community has been resilient through attacks and changes—but it is time to fully sunset the Harmony network.”

To mitigate the threat, Harmony is proposing to move Harmony’s ONE token to Ethereum and use newly issued tokens to fund the ecosystem's new “The Remix Economy for AI Video” initiative. Validators, who verify network transactions, could take governance roles or join the AI-video business.
