Harmony developers have proposed voluntarily shutting down the seven-year-old blockchain and migrating its native ONE token to Ethereum, citing the unsustainable cost of defending the network against increasingly capable state actors and AI agents. The nonbinding plan marks a rare instance of a major layer-1 project proactively sunsetting its mainnet rather than fading into irrelevance due to lack of usage.

Market Context

The proposal comes after a period of severe volatility and security breaches for the once-hyped Ethereum rival. Harmony’s Horizon bridge was drained of nearly $100 million in June 2022, an attack attributed by the FBI to North Korea's Lazarus Group. This event precipitated a steep decline in token perception, with ONE prices falling as much as 99% from their peak. More recently, an August 11 exploit allowed an attacker to mint over three trillion unauthorized ONE tokens, forcing a controversial chain rollback that erased more than 109,000 transactions from history.

Analysis

The decision reflects a shift in the threat landscape for decentralized networks. In a statement on X, the project noted that while the community had been resilient since the mainnet launch in 2019, the threats posed by state actors and AI agents had become too great to manage on the current infrastructure. Unlike typical failed chains that lose users gradually, Harmony is attempting an orderly exit with a specific migration path. Under the plan, a final snapshot of ONE balances will be taken, and matching ERC-20 tokens will be automatically issued to the same wallet addresses on Ethereum. This includes holdings in wallets, staking, validator rewards, and centralized exchanges, removing the need for holders to claim tokens manually.

The most novel aspect of the proposal involves the redirection of future economic incentives. ONE was originally issued to reward validators for securing the blockchain. With the chain disappearing, these future emissions are proposed to fund the "Remix Economy for AI Video," a subscription service where creators publish prompts and assets for reuse by humans and AI agents. This pivot suggests a strategic attempt to retain community value by transitioning from blockchain infrastructure to an AI-driven application layer.

Key Numbers

- ONE token traded around $0.00073 on Monday, down almost 4% over 24 hours.

- Peak ONE price reached approximately $0.38 in October 2021.

- Network held more than $1 billion in user deposits by January 2022, with $747 million in DeFi Kingdoms alone.

- August exploit minted over 3 trillion unauthorized ONE tokens.

- Chain rollback erased more than 109,000 transactions.

- $1.372 million set aside to compensate validators who shut down nodes on time.

- Validators can begin shutting down nodes from 7 a.m. Pacific on Sept. 10.

- ONE price fell as much as 99% from peak following the 2022 bridge hack.

What to Watch

Traders should monitor the specific validator shutdown date of September 10, when nodes can begin closing from 7 a.m. Pacific, as this marks the operational start of the network's sunset. Attention will also shift to the timeline for the ERC-20 token migration on Ethereum, which is critical for maintaining liquidity and ensuring holders receive their assets without manual intervention. Additionally, market participants need to watch for any subsequent regulatory scrutiny or community vote deadlines that could influence the final execution of the migration and the viability of the proposed AI video venture.
