Ethereum Ecosystem Contributions - Polygon hosts Polymarket, a successful "not just boring finance" application, demonstrating valuable use cases beyond traditional finance [1] - Polygon has supported various applications requiring high scalability within the Ethereum ecosystem [1] - Polygon invested significantly in ZK-EVM proving technology early on, contributing to the advancement of the field [2] - Polygon has developed infrastructure for proof aggregation (AggLayer) and other technologies [2] Philanthropic Efforts - Sandeep Nailwal contributed personally to CryptoRelief_, supporting biomedical infrastructure and research in India [2] - Sandeep Nailwal voluntarily returned $190 million from SHIB tokens, enabling the Balvi open-source anti-airborne-disease biotech program [3] - CZ (Binance) donated $10 million in BNB to support the Balvi program, with additional ~$20 million contributed personally [3] ZK Technology and L2 Landscape - The market structure has evolved, with L2 teams and ZK teams becoming separate entities, potentially more efficient than in-house development [5] - The author hopes Polygon can adopt readily available ZK technology for its PoS chain to achieve full security guarantees from the Ethereum L1 [6] - ZK technology has improved significantly, with proving costs around $0.0001 per transaction, challenging the perception of ZK being unviable for hyperscale applications [6]

RT A₿del ∞/21M (@dimahledba)Concrete plan to build a Starknet-based L2 on top of ZCash ?- plumbing of the TZE architecture in Zebra using librustzcash- create the stark verification TZE and integrate stwo Cairo proof verification- update a ZCash SDK to be able to construct transactions using the new TZE- generate a proof of Bitcoin header chain- submit and verify the proof to a ZCash modified node- integrate this TZE pipeline in a modified Starknet sequencerHold my beer for a month and let's see.A real cool ...

and again, this is not necessarily an L2 exclusive problem, L1s without sufficient geo decentralization are also vulnerable to thisthe difference is that the L1 requires more things to go wrong, so it is generally, probabilistically more resilient (but not always) ...

漏掉了还有个strk第一个是op，第二个是arb，第三个就是strk第四个是ZK？何币 (@hebi555):Perp就是跟L2一样第一个是op，第二个是arb，第三个就是zk了 ...

Layer 2 (L2) Solutions - Perpetual Protocol (Perp) aligns with Layer 2 solutions [1] - Optimistic Rollups (OP) is the first L2 solution [1] - Arbitrum (ARB) is the second L2 solution [1] - Zero-Knowledge Rollups (ZK) is the third L2 solution [1]

Stablecoin Flows - Solana 记录了所有 L1 和 L2 链中最大的 24 小时稳定币流入量 [1]

RT Brother Odin (@odin_free)KAAABOOOOM !!!!!new ALL-TIME record across all ETH & BTC L2s.POW! just pushed Starknet to 273.4 UOPS sustained over 24h2.47k UOPS peakprevious global record: Base (168.6 UOPS)Starknet = multicalls.1 tx = many user ops.real scalability is measured in UOPS, not TPS. https://t.co/tSkW0619PT ...

Layer 2 (L2) Performance - Starknet processes 10x the maximum UOPS (unidentified operations) of all other L2s combined on mainnet [1] - This comparison considers UOPS counted outside execution on Starknet [1]

DeFi & L1/L2 Updates - Crypto.com Research & Insights 发布 DeFi+L1/L2 更新报告 [1] - Solana 在过去 12 个月内产生了 28.6 亿美元的收入 [1] - Solana 过去一年收入占总收入比例未提及，需进一步分析 代币与基金 - Tether 计划为一个 DAT 公司筹集资金，以收购其 XAUT 代币 [1] - Grayscale 推出了以太坊和 Solana ETP 的质押服务 [1]

RT L2BEAT 💗 (@l2beat)Exciting news for the ZK Stack builders!We’re looking forward to seeing Atlas on mainnets ⚡️Soon after, Airbender will make its way to the ZK Catalog! ...
