Harmony, the blockchain project behind the ONE token, has proposed a major change to its future: shutting down its existing Layer-1 blockchain and moving the ecosystem toward Ethereum.
The proposal is unusual because Harmony’s developers cited not only conventional blockchain security concerns but also the growing challenge posed by increasingly capable AI agents and state-level threats.
According to The Block, Harmony’s proposal would eventually sunset the existing network and migrate the native ONE token to Ethereum. The project also wants to redirect resources toward an AI-focused video creator economy.
The decision highlights a larger issue facing smaller blockchain networks: maintaining a secure independent blockchain can become increasingly difficult as attacks, automated systems and infrastructure requirements grow.
Why Harmony Wants to Shut Down Its Layer 1
Running an independent blockchain requires a substantial security and infrastructure ecosystem.
A Layer-1 network needs validators, developers, infrastructure operators, wallets, exchanges and applications. It also needs enough economic security to make attacks prohibitively expensive.
For smaller networks, maintaining this ecosystem can become difficult.
Harmony has experienced security problems in the past, and its latest proposal suggests that the project’s developers believe the cost and complexity of continuing with a separate Layer-1 network may no longer justify the benefits.
The growing capabilities of AI systems add another layer to that problem.
AI agents can increasingly operate computers, interact with software systems and execute sequences of tasks with limited direct human involvement.
For blockchain networks, that could create new opportunities but also new attack surfaces.
AI Agents Are Changing the Security Equation
Traditional cybersecurity threats generally involve human attackers or automated programs executing pre-defined instructions.
AI agents can potentially operate with much greater flexibility.
An advanced agent can analyze an environment, identify opportunities, interact with interfaces and adjust its strategy based on what it observes.
That creates a new question for decentralized networks:
Can a small blockchain continuously defend itself against highly automated and adaptive attackers?
Harmony’s decision suggests that the developers believe this challenge deserves serious consideration.
The issue is not necessarily that AI has already made smaller blockchains obsolete.
Instead, it highlights a potential future in which security requirements become increasingly sophisticated.
Why Ethereum Is Attractive
Moving ONE to Ethereum would allow Harmony to leverage an established blockchain rather than continuing to operate its own Layer-1 infrastructure.
Ethereum has a much larger developer ecosystem, substantial economic activity and an extensive infrastructure network.
By moving the token and ecosystem toward Ethereum, Harmony could potentially reduce some of the operational requirements involved in maintaining an independent consensus network.
The trade-off is that Harmony would lose some of the independence associated with operating its own Layer 1.
That is a significant strategic decision.
The Future of Small Layer-1 Networks
Harmony’s proposal could become part of a broader trend.
During earlier cryptocurrency cycles, launching a Layer-1 blockchain was often presented as a core strategy.
Projects competed by offering:
- faster transactions
- lower fees
- specialized applications
- different consensus models
- developer incentives
But maintaining a blockchain independently is difficult.
Competition has intensified.
Ethereum, Solana and other large ecosystems have attracted significant developer and user activity.
Layer-2 networks have also changed the economics of blockchain scaling.
As a result, smaller projects increasingly have to answer a difficult question:
Does operating an independent blockchain actually create enough value to justify the security and infrastructure cost?
Harmony’s AI Pivot
The proposal reportedly also includes a future direction involving AI-generated video.
Harmony wants to redirect validator-related resources toward an AI video creator economy.
That creates an unusual combination:
Blockchain → AI → creator economy
The strategy suggests that Harmony may no longer see blockchain infrastructure itself as the primary growth opportunity.
Instead, blockchain could become part of a broader technology stack supporting AI and creator applications.
Whether this works remains uncertain.
What This Means for ONE Holders
For holders of ONE, a blockchain shutdown proposal would be highly significant.
A migration from Harmony’s native network to Ethereum could change:
- how tokens are held
- which wallets support the asset
- exchange infrastructure
- smart-contract interactions
- network fees
- application compatibility
Holders would therefore need to follow official migration instructions carefully if the proposal proceeds.
No investor should assume that a migration is automatic.
Blockchain migrations can involve deadlines, technical procedures and exchange-specific arrangements.
Is This the End of Harmony?
Not necessarily.
The proposal represents a potential end to Harmony’s existing Layer-1 architecture.
It does not necessarily mean that the broader project disappears.
Instead, Harmony could become an ecosystem built on another network while pursuing AI-related opportunities.
This model resembles the way some software projects operate across existing infrastructure instead of maintaining their own blockchain.
Why the Story Matters Beyond Harmony
The bigger story is about blockchain economics.
The cryptocurrency industry spent years building alternative Layer-1 networks.
Now the market is increasingly asking whether every application really needs its own chain.
Operating on an established network can provide access to:
- security
- liquidity
- developers
- wallets
- infrastructure
- established standards
For smaller projects, those benefits can outweigh the advantages of independence.
Final Takeaway
Harmony’s proposal to shut down its Layer-1 blockchain represents a notable shift in strategy.
The project has cited growing security challenges, including concerns about AI agents and state-level threats, while proposing a migration of ONE toward Ethereum.
The decision demonstrates how the blockchain industry is changing.
The question is no longer simply:
“Can you build a blockchain?”
It is increasingly:
“Can you secure, maintain and grow that blockchain economically?”
Harmony appears to be exploring a different answer: build on established infrastructure and redirect resources toward AI and the creator economy.
For ONE holders and the wider crypto industry, the outcome will be worth watching.
