The Layer 1 blockchain Harmony, once a major competitor to Ethereum, proposed to shut down its mainnet on Sunday, citing threats from AI entities and nation-state actors as too severe. The Harmony team stated on X that since the mainnet launched in 2019, the community has experienced multiple attacks and transformations, and now it is time to completely discontinue the Harmony network. To mitigate the threats, the team proposed migrating the ONE token to Ethereum and redirecting the issuance of newly minted tokens to its new initiative "The Remix Economy for AI Video."According to the proposal, the migration will determine the allocation of alternative tokens received by each holder on Ethereum based on the ONE balance recorded at the final block of the network (i.e., a snapshot), covering wallets, staked tokens, validator rewards, smart contracts, and centralized exchanges. The alternative tokens will be airdropped to the same wallet address on Ethereum, and exchanges will also migrate to the new tokens. Although the proposal states that holders do not need to submit a claim, multi-signature vaults, liquidity pools, and on-chain applications cannot be migrated, and users are urged to exit all smart contracts by September 10, 2026. Harmony also proposed to pay eligible validators and their delegators in four installments from a pool of $1.372 million, provided that validators maintain their stakes, sign agreements, and serve governance roles.This migration proposal is the latest case of blockchain networks facing increased scrutiny due to attacks. In August of this year, Harmony confirmed it was attacked, with the attackers creating approximately 4 billion unauthorized ONE tokens, prompting the team to release a patch and consider a rollback.

Goldman Sachs significantly raised its industry forecast in the latest global optical module report, expecting the global optical module market size to reach approximately $67.7 billion, $131.4 billion, and $148.5 billion in 2026, 2027, and 2028 respectively, an increase of 33%, 81%, and 115% compared to previous forecasts.Goldman Sachs believes that this round of upward revision is not solely due to the increase in the number of AI servers; more importantly, the architecture of AI servers is continuously migrating towards high-speed networks, coupled with the increase in the number of optical modules required for a single GPU or ASIC chip, driving rapid growth in demand for 800G, 1.6T, and even 3.2T.

According to CoinDesk, Ethereum core developers have included EIP-8141 (Frame Transactions) in the 2027 Hegotá upgrade plan. During the core developer call on August 27, the proposal was marked as "Scheduled for Inclusion," meaning it will become part of the network update rather than just a candidate proposal. Ethereum co-founder Vitalik Buterin, one of the ten authors of the proposal, stated on X on Sunday night that Frames have made significant progress in the past few months.Frames aim to address the issue where users hold stablecoins but cannot transfer them due to a lack of ETH. It splits transactions into independent steps such as authorization verification, fee payment, and instruction execution, allowing the sender and payer accounts to no longer have to be the same. For example, payment applications can cover fees themselves or settle ETH bills on behalf of users after collecting stablecoins, while the Ethereum network still prices in ETH, and users do not need to purchase ETH. Unlike existing wallet solutions that rely on third-party services, Frames will achieve this capability through the standard Ethereum transaction process.Additionally, Frames will bundle operations that need to be executed simultaneously, such as authorization and submission in token transactions, with authorization being revoked if the transaction fails; it also allows accounts to customize transaction approval rules, enabling the replacement of private keys or the adoption of quantum-resistant keys without needing to migrate funds to a new address. Currently, the specification is still a draft, and details may be adjusted before the Hegotá upgrade, with users unable to use Frames yet.
