Aggregation Techniques - Grouping Sets, Rollup, and Cube are efficient methods for performing multiple aggregations on a single table scan [1] - These techniques enhance query efficiency by minimizing table scans [1] Efficiency Improvement - The industry emphasizes the efficiency gains from using these aggregation methods [1]

So, wen Polkadot 2.0?Polkadot 2.0 has three core technical pillars:→ Async Backing ✅ Boosts rollup throughput.→ Agile Coretime ✅ Allocates coretime on a rental basis.→ Elastic Scaling 🔜 Rollups dynamically scale up their compute power.The passing of Referendum 1721 will enable the RFC103 runtime, which will be enacted on Monday September 8th.Once enacted, the Relay Chain Elastic Scaling feature is complete!Ref 1721 is currently passing with 100% AYE vote. ...

RT Uma Roy (@pumatheuma)This isn’t just another logo x logo partnership—this is a big fucking deal. So excited to form a deep partnership between @SuccinctLabs and @OffchainLabs to bring ZK to their rollup stack.Over the next year, our teams will collaborate on a ZKP version of Arbitrum’s rollup stack. The ZK-powered stack will be available for any Arbitrum chain to use, including Arbitrum One ($19B in TVL), Robinhood Chain, @convergeonchain by @ethena_labs and more.What are the implications?Validation of e ...

Technology & Infrastructure - Rollup tokens are being acquired for "zk exposure" (零知识证明)[1] - Cysic is shipping hardware capable of 1.31 million proofs per second, contradicting claims of impossibility [1] - Infrastructure layer is generating significant revenue [1] Challenges & Opportunities - High proof costs are impacting margins [1] - The industry is moving beyond application layer focus [1] - There's a shift from chasing AI agents to focusing on hardware solutions [1]

Market Trends - Wormhole 可能遭受 L0 层攻击，市场可能出现反弹 [1] - X 平台上的 Rollup 达到 50K [1] Events & Interviews - 行业正在进行关于 Legion 创始人、Arbitrum 联合创始人、ZeroDev 创始人、Infinifi 首席执行官和 Extended 创始人的访谈 [1]

Investment Focus - The report seeks to identify the rollup with the largest current investment [1]

Overview - Puffer Finance's UniFi V2 testnet is live, inviting builders to explore Ethereum-native infrastructure [1] - UniFi addresses Ethereum's fragmentation and fosters ecosystem growth through based rollup technology [1] Technology and Features - UniFi-OP enables Ethereum builders and users to avoid choosing a "winning" L2 or giving up revenue [2] - Rollup owners can share priority fees and MEV with validators through UniFi AVS [2][3] - UniFi V2 offers governance-optional rollups, custom fee markets, and KYC-gated or fully permissionless chains [3] - Users experience sub-10ms confirmations, one-click exits to L1, and seamless L1 interaction [3] - Multi-TEE provers attest each block in less than 1 second, enhancing security [4] Security and Composability - UniFi AVS leverages EigenLayer for shared security in preconfirmations [5] - Pragmatic composability is achieved with atomic withdrawals from L2 [9] - Trust-minimized, real-time proving is implemented [9] - Security model focuses on transaction volume and speed as key performance indicators (KPIs) [6] Roadmap and Future Development - Progressive onboarding of independent gateways for decentralization [8] - Future upgrades include ZK proving, Universal Registry Contract (URC) integration, and native L1↔L2↔L2 calls [8]

L2 Decentralization Standards - Vitalik endorses six Ethereum L2s meeting L2Beat's Stage 1 decentralization standards, advocating for a trustless ecosystem [1] - L2Beat's framework categorizes L2s based on security and governance, with Stage 1 requiring a Security Council and permissionless exits [4][5] - Stage 1 requires a large, diverse multisig with 75%+ approval and 26%+ independent members to prevent malicious actions [5] L2 Ecosystem Evolution - As of December of last year, there were approximately 50 rollups and 70 alt-DA L2s holding over $50 billion in TVL [2] - Only six projects had Security Councils with at least eight members and 75% thresholds [3] - In June, out of 136 projects reviewed, only 26 retained L2 status, and just 8 reached Stage 1 [4] - L2Beat's upgrades include Liveness Tracking to flag downtime and the UOPS/TPS Ratio Chart to measure account abstraction adoption [6][7] Future Goals - The industry aims for withdrawal times under an hour, ideally seconds, reducing reliance on risky third-party bridges [9] - The standard is set for more teams to meet Stage 1+ requirements [9]

Technology & Innovation - Parity Technologies' Polkadot Deployment Portal team receives recognition for July upgrades [1] - Upgrades focus on making rollup launching on Polkadot faster, safer, and smarter [1] - Improvements include Kubernetes deployments and automatic Coretime renewals [1] - Parity emphasizes builder-first innovation [1]

the first-ever zkRaffle launched on @GalxeQuest in collaboration with @SuccinctLabscongrats to the Succinct team for pushing the boundaries of crypto and ZK innovationSuccinct Foundation (@SuccinctFND):5/ PROVING THE FUTUREFinally, the airdrop includes existing users of the Prover Network and top rollups.Succinct promised to make every rollup a ZK rollup. The airdrop is delivering on it by ensuring past, present and future users are aligned with the network from day one. https://t.co/JkFnEBiuwh ...
