Harmony Proposes L1 Shutdown, ONE Move to Ethereum in AI Pivot
Harmony, once promoted as a rival to Ethereum, built a Layer 1 network around its native ONE token. The project is now considering an exit from blockchain infrastructure, citing security risks intensified by advances in artificial intelligence. The proposed shutdown would mark a sharp reversal for the former high-profile chain and redirect its resources toward an AI-driven market for remixing and distributing video content.
Under the proposal, Harmony would take a final snapshot before closing its Layer 1 and migrate ONE to Ethereum, where replacement tokens would be distributed to existing holders through an airdrop. The team plans to focus next on an AI video-remix economy supported by autonomous agents for content creation and circulation. As of Sept. 9, 2026, Harmony had not disclosed the snapshot date, conversion ratio or financial terms.

The history behind this eventEthereum Foundation Makes ‘Hardness’ a 2026 Priority to Bolster L1 Censorship Resistance and Privacy
The Ethereum Foundation has long advanced Ethereum protocol research and coordinated its ecosystem. As the network scales and its user experience improves, transaction censorship, privacy leaks and threats from quantum computing are drawing greater attention. “Hardness” has therefore become a key defense for preserving L1 decentralization, neutrality, security and permissionless participation.
In its 2026 protocol update plan, the Ethereum Foundation formally designated “Hardness” as its third core priority, covering L1 censorship resistance, privacy protection and post-quantum security, with dedicated researchers assigned to the work. The foundation has not disclosed funding, a complete timeline or launch dates for the individual upgrades.
