Vitalik: SNARKs are expected to bring their computational overhead down to single-digit multiples by the end of this decade.

Harmony announced plans to fully shut down its network and migrate its native token ONE to Ethereum, citing excessive threats from state-sponsored attackers and AI agents. Per the proposal, validators may cease operating nodes starting at 7 AM Pacific Time on September 10, 2026. The project will pivot its focus to the "AI video secondary creation economy": it plans to open prompts and materials for creators and fans to produce secondary works, with AI agents expanding content branches into more stories. For the migration, a snapshot will be taken at the network’s final block, and new ONE tokens will be airdropped to corresponding Ethereum wallet addresses (no active claim required). Delegated staking and unclaimed rewards will be transferred to each governor’s treasury. Multisig wallets, liquidity pools, and on-chain applications cannot be migrated; Harmony urges users to exit all smart contracts by September 10, 2026. Regarding the AI video business, Harmony is recruiting operators responsible for video generation, media distribution, and content moderation. In the first year, the platform will subsidize hardware costs and boost video generation demand. Operators must stake tokens to qualify, earn rewards based on service uptime, and cover other operational costs. The platform will also track and incentivize contributions to original works, secondary creations, and promotion. Harmony will provide a total one-time compensation of $1.372 million to validators and their delegates who shut down nodes on time, sign relevant agreements, retain staking, and continue participating in governance, with the compensation disbursed over four quarters. The total supply and issuance rate of ONE will remain unchanged; future token issuance will be allocated to the AI video project, with related arrangements to be made after soliciting feedback from governors.

Harmony announced in a post that it plans to fully shut down its Harmony network and migrate its native token ONE to Ethereum, citing excessive threats from state-sponsored attackers and AI agents. Per the proposal, validators may stop operating nodes starting at 7:00 AM Pacific Time on September 10, 2026, as the project shifts its development focus to the "AI video secondary creation economy". The migration plan will take a snapshot at the network’s final block, with new ONE tokens airdropped automatically to corresponding Ethereum wallet addresses—no action is required from holders. Delegated staking and unclaimed rewards will be airdropped to each governor’s treasury. Harmony noted that multi-signature wallets, liquidity pools, and on-chain applications cannot be migrated, urging users to exit all smart contracts before September 10. Relevant token contracts, snapshot calculations, and airdrop scripts will be made public for auditing. The project also plans to launch a one-time compensation program totaling $1.372 million, available to validators and their delegates who shut down nodes on schedule, sign the agreement, retain staked assets, and continue serving as governors, with payments distributed over four quarters. The total supply and issuance rate of ONE will stay unchanged; future minted tokens will be allocated to new AI video projects, subject to feedback from governors.

Well-known trader Killa stated in a post that BTC typically enters a consolidation phase after every sharp rally or pullback. Having experienced a strong rally, he forecasts the market will move into a range-bound period next. With the current trend having turned bullish, he leans toward going long on dips. He stressed that this does not rule out shorting at the highs of the consolidation range, but such trades are counter-trend operations and require corresponding adjustments to position sizes.

Ukrainian President Volodymyr Zelenskyy announced that the first meeting between Ukrainian and U.S. negotiators has concluded.

Arbitrum co-founder Steven Goldfeder and Solana co-founder Toly have engaged in a debate over on-chain transaction fees, MEV protection, and the single sequencer model. Steven argued that surface-level fees alone should not be compared, noting that Arbitrum One and Robinhood Chain proactively prevent front-running and most malicious MEV, while some chains claiming lower fees carry higher MEV costs—including front-running targeting retail users. He stated he would rather pay clear, upfront fees than incur hidden losses from front-running, sandwich attacks, and other issues just to secure lower fees. Toly countered that Arbitrum currently has worse bid-ask spreads and higher fees. He explained that the 10% cut it takes from fees, when converted to basis points, already exceeds the sandwich attack loss rate—estimated to be roughly 10 times that rate—without even accounting for spread impacts. He emphasized: “A single sequencer that prioritizes maximizing shareholder value will never outcompete permissionless competition.”

On-chain detective ZachXBT has issued a community alert, reporting that over the past three days, multiple verified WOO X users have complained their withdrawals remain stuck in "pending" or "processing" status. As of the time of his post, WOO X has not released a statement on the matter. WOO X was incubated by Kronos Research and acquired by FusionX Digital in the fourth quarter of 2025. ZachXBT pointed out that FusionX Digital is reportedly linked to BitMart founder Sheldon Xia. ZachXBT also noted that BitMart announced on July 26, 2026, it would cease operations and restructure, leaving users unable to access millions of dollars in trapped funds, with complaints rising steadily on the X platform. Sheldon Xia only issued a vague statement asserting user assets are secure, but these claims have not been independently verified.
