Harmony Proposes Blockchain Shutdown Amid AI and State Actor Threats
Harmony, a blockchain platform that once vied for prominence alongside Ethereum, has put forth a proposal to cease operations on Sunday, citing escalating threats from artificial intelligence agents and state-sponsored actors as the primary drivers for the decision.
The announcement arrives as the cryptocurrency industry grapples with an intensifying wave of sophisticated cyberattacks, many of which are reportedly amplified by advanced AI models such as 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 stated on the social media platform 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 navigate these challenges, Harmony is proposing a migration of its native ONE token to the Ethereum blockchain. The initiative would leverage newly issued tokens to finance a new ecosystem project dubbed “The Remix Economy for AI Video.” Under this plan, network validators, responsible for verifying transactions, would have the option to assume governance roles or participate in the AI-video venture.
Launched in 2019, Harmony operates as a layer-1 blockchain utilizing a proof-of-stake consensus mechanism, where validators commit tokens to secure the network, and sharding technology, which divides transaction processing into parallel segments. This architecture was designed to address the “blockchain trilemma” by enhancing transaction capacity without compromising security or decentralization.
Transitioning ONE to Ethereum
According to Harmony’s proposal, the migration process would involve recording ONE balances at the network’s final block through a “snapshot” to determine each holder’s allocation of replacement tokens on Ethereum. This process is intended to encompass all wallets, staked tokens, validator rewards, smart contracts, and holdings on centralized exchanges.
Replacement tokens would be distributed via airdrop to the same wallet addresses on Ethereum. Delegated stakes and unclaimed rewards would be directed to individual governor vaults, and exchange listings for the token would also transition to the new platform.
While the proposal indicates that holders would not be required to submit a claim for their replacement tokens, users with assets held within smart contracts face a separate deadline.
“Multisig safes, liquidity pools, and onchain apps cannot be migrated; users are urged to exit all smart contracts before September 10, 2026,” the Harmony Team cautioned.
Harmony also plans to compensate eligible validators and their delegators from a dedicated pool of $1.372 million, distributed in four quarterly installments. This compensation is contingent upon validators maintaining their stakes, signing an agreement, and assuming governor roles.
“The ONE token’s total supply and emission rate will remain unchanged. Tokens issued through emissions will now be allocated to our new mission, “The Remix Economy for AI Video”, subject to governor feedback,” the team elaborated.
AI and Crypto Security Under Scrutiny
The proposed migration follows a series of high-profile attacks that have intensified scrutiny of blockchain network security.
In August, Harmony confirmed an exploit that resulted in the creation of approximately 4 billion unauthorized ONE tokens. The team subsequently released a patch and explored the possibility of a rollback, which would revert transactions by restoring an earlier state of the blockchain.
Sunday’s announcement on X highlights the increasing influence of AI in cryptocurrency security, with companies reporting suspected AI-assisted attacks and developers employing AI to identify and rectify vulnerabilities.
Earlier this year, in July, Coinkite, the maker of the Coldcard hardware wallet, suggested that an attacker may have used AI to exploit a flaw that made wallet keys more susceptible to guessing—a vulnerability that their own AI review had overlooked. The company subsequently overhauled its security measures in August after experiencing thefts exceeding $100 million.
In the wake of the Coldcard incident, developers established the Bitcoin Red Team, a volunteer group dedicated to proactively identifying vulnerabilities before they can be exploited by malicious actors. This team integrates AI models, including Moonshot AI’s Kimi K3, with human expertise to scrutinize wallets, payment applications, and other Bitcoin software, privately alerting developers to any discovered flaws.
The Bitcoin Red Team has grown to approximately 20 to 25 volunteers, according to pseudonymous member and developer Calle. He stated that the team has not identified any issues within Bitcoin’s underlying protocol.
“The reason why the Bitcoin Red Team exists right now is because we need to get ahead of the attackers as fast as possible,” Calle told Decrypt.
