US government backs OpenAI in copyright fight over LLM training data The U.S. government filed an amicus brief supporting OpenAI in the ongoing dispute over training large language models on copyrighted material. The brief argues the United States has a strong interest in keeping its AI industry competitive and in setting the global standard for AI practice and procedure. For any protocol built around AI-generated game assets or media, the legal treatment of training data feeds directly into how those assets' rights and provenance eventually get resolved. 出典: https://techcrunch.com/2026/09/02/u-s-government-sides-with-openai-on-issue-of-training-llms-on-copyrighted-material/
World open-sources ProveKit, a zero-knowledge identity proving toolkit World has open-sourced ProveKit, letting users prove identity claims like age or nationality without exposing personal data, a tool already running inside World ID since April. The release is a step toward portable, privacy-preserving proof-of-personhood infrastructure. For any onchain game or agent-heavy protocol trying to separate real users from bots, that kind of attestation layer is foundational plumbing. 出典: https://www.theblock.co/news/ecosystems/2026-09-02-world-provekit-zero-knowledge-identity-proving-toolkit-413364
Arbitrum DAO reports $6.2 million in first-half income as Robinhood Chain adds new revenue stream Arbitrum DAO disclosed $6.2 million in first-half income, with licensing fees accounting for 35% of July's total, the first month Robinhood Chain was live on mainnet. The figures show a Layer 2 DAO diversifying beyond sequencer fees into licensing deals with consumer-facing chains, a model that game-focused chains looking for sustainable treasuries are watching closely. 出典: https://www.theblock.co/news/ecosystems/2026-09-02-arbitrum-dao-reports-6-2-million-first-half-income-robinhood-chain-adds-new-revenue-stream-413345
Today's Pick
Today's pick is "ブロックチェーンゲームの教科書" (The Blockchain Game Textbook). As generative AI speeds up production timelines for blockchain games, a shared vocabulary between design and economy teams is worth having on hand — this title aims to be exactly that.
On-Chain Data Point
As of September 3, 2026, 06:30 JST (DefiLlama), Ronin — the blockchain built for Web3 gaming — holds $10.6M in total value locked, versus Ethereum's $48.13B and Base's $5.47B. That gap is a reminder that gaming-chain liquidity remains thin relative to general-purpose L1s and L2s even as the intersection narrative grows.
The Take
Three separate signals point to the same maturing layer underneath Web3 gaming: legal, identity, and revenue infrastructure catching up to the technology. Washington backing OpenAI's position on training with copyrighted material matters directly for AI-generated game assets, since it tilts the legal ground under that exact kind of content toward model builders rather than rights holders. ProveKit gives onchain games a shipped way to tell real players from bots without collecting personal data. Arbitrum's licensing income from Robinhood Chain shows consumer distribution, not sequencer fees, becoming the revenue model gaming chains will copy next. None of it moves TVL, but all of it de-risks building at the intersection.
