ChainCatcher news, in response to community member Daniel Wang's proposed naming label #BattleTested for the L2 network Stage 2, Ethereum co-founder Vitalik posted on the X platform stating: "This is a good reminder: the second stage is not the only factor affecting security; the quality of the underlying proof system is equally important. This is a simplified mathematical model that shows when to enter the second stage:Each security council member has a 10% independent 'break' chance; we consider activity failure (refusal to sign or key unavailability) and security failure (signing the wrong thing or key being hacked) as equally likely; the goal: to minimize the likelihood of protocol collapse under the above assumptions.Stage 0 security council is 4/7, Stage 1 is 6/8; please note that these assumptions are very imperfect. In reality, council members have 'common mode failures': they may collude, or all be coerced or hacked in the same way, etc. This makes both Stage 0 and Stage 1 more insecure than shown in the model, so entering Stage 2 earlier than the model suggests is the best choice.Additionally, note that by turning the proof system itself into multiple independent systems via multi-signature, the probability of proof system collapse can be greatly reduced (this is what I advocated in previous proposals). I suspect that all Stage 2 deployments in the past few years will be like this. Considering this, here is the chart. The X-axis is the probability of proof system collapse. The Y-axis is the probability of protocol collapse. As the quality of the proof system improves, the optimal stage shifts from Stage 0 to Stage 1, and then from Stage 1 to Stage 2. Using a proof system of Stage 0 quality for Stage 2 is the worst.In short, @l2beat ideally should showcase proof system audits and maturity metrics (preferably proof system implementations rather than the entire aggregation, so we can reuse them) and stages."

ChainCatcher news, according to official information, the Ethereum L2 Superseed based on OP Stack announced on platform X that the SUPR token will be available for claiming at 22:00 Beijing time on May 5, with no deadline for claims.

ChainCatcher news, Unichain announced that it has implemented a block construction mechanism based on TEE (Trusted Execution Environment), becoming the first L2 network to adopt this approach. This design enables transaction priority ordering, MEV protection, and transaction rollback protection, and supports future verifiable block features.Unichain stated that the traditional Rollup sorting mechanism is usually an offline operation, making it difficult to audit, while its TEE sorting system can publicly prove the transaction order, reducing MEV value loss. In addition, the rollback protection mechanism will prevent users from losing Gas in failed transactions, enhancing price accuracy and block space utilization efficiency. The aforementioned features are supported by Rollup-Boost, developed in collaboration with Uniswap Labs and Flashbots.

ChainCatcher news, according to Cointelegraph, the number of independent addresses in the Ethereum Layer 2 ecosystem has reached 13.6 million, a record high, with a growth of 74% in 7 days. The dominance of Layer 2 has reached 6.69 times, with weekly transaction volume exceeding 832,000.

ChainCatcher news, according to the official announcement from the Ethereum Layer2 network Red­dio, the token economic model for RDO has a total supply of 10 billion tokens, which are allocated as follows:Community (8.00%): Aimed at accelerating user adoption and rewarding early supporters through marketing activities, airdrops, community incentives, and educational initiatives.Security and Network Incentives (25.00%): The largest portion allocated for mining rewards, which contribute computational resources to the proof-of-authority consensus layer. This allocation has a 10-year no-cliff period, enhancing long-term network security and validator loyalty.Ecosystem Growth (22.76%): Supports project development, grants, partnerships, and the launch of dApps. Nearly half (70.1%) of this funding will be unlocked at TGE, facilitating immediate growth activities, while the remainder will vest after 48 months.Treasury (6.96%): Held for operational flexibility, liquidity provisioning, and emergency actions under DAO governance. At TGE, 15% is liquid, with the remaining portion unlocking linearly over four years.Contributors (21.80%): Allocated to core team members and early builders. A 12-month cliff ensures commitment, followed by a 24-month linear vesting. This aligns with long-term incentives and ensures continuity of contributions.Strategic Investors (15.48%): Aimed at early supporters providing funding and market support. Tokens will undergo a 6-month cliff period, followed by an 18-month linear vesting period. This timeline promotes strategic alignment while preventing speculative pressure.

ChainCatcher news, Uniswap founder Hayden Adams recently posted on the X social platform, expressing concerns about the confusion surrounding Ethereum's current scaling strategy. Adams emphasized that Ethereum has invested over 5 years in developing a horizontal scaling approach based on L2 and should not waver during the "final sprint phase."He criticized the conflicting voices within the community, which on one hand claim to follow the "rollup-centric roadmap," while on the other insist that "important functions must remain on L1." Adams stated, "I support improvements in L1 scaling; the rollup-centric roadmap actually requires these improvements," but he opposes frequent changes in strategic direction.Adams called for the community to "choose a path and work to reduce the associated risks," rather than "changing the narrative and strategy every month." He also clearly expressed his opposition to the approach of "trying all methods," believing that it is worse than not choosing any method at all.

ChainCatcher news, Ethereum co-founder Vitalik Buterin stated at the "Web3 Scholars Summit 2025" in Hong Kong that Ethereum's long-term goal is to achieve 12-second native asynchronous communication between L1 and L2, reducing bridging latency and costs.To this end, he proposed a "four-step" plan: including a "ZK+TEE+OP two out of three" design, asynchronous reading of L1 through L1SLOAD, a unified proof integration mechanism, and deploying low-latency validators. He emphasized that in the future, users can still use intent-based models to achieve faster or more cost-effective experiences, but the underlying communication system will tend towards low cost and high coupling.

ChainCatcher message, Ethereum founder Vitalik Buterin discussed the development of Ethereum in 2025 at the ETHGlobal Taipei event, stating that even though most activities occur on L2, L1 scalability should not be overlooked. He listed several scenarios where L2 applications still rely on L1: L1 anti-censorship guarantees, asset transfers between L2s, large-scale exits from L2, asset issuance on L1, Keystore wallets, and L2 proof submissions.

ChainCatcher news, Startale Group announced that it will use the profits from the sequencer of the Ethereum L2 blockchain Soneium, jointly developed with Sony Group, to purchase ASTR tokens in the market, further promoting the integration of Soneium and the Astar ecosystem as well as future asset consolidation.It is reported that Soneium is an Ethereum L2 developed and operated by Sony Block Solution Labs (jointly held by Sony headquarters and Startale) and led by Astar founder Sota Watanabe. Its sequencer is responsible for transaction ordering, packaging, and submitting to Ethereum L1, while collecting transaction fees.

ChainCatcher news, Synthetix founder Kain stated that the Ethereum mainnet is facing economic pressure from a sharp decline in gas fees and ETH burn due to L2 scaling diverting transaction activity and the introduction of blobs from EIP-4844, which reduces data availability costs.Kain believes that the rise of L2 has intercepted the profits that originally belonged to the mainnet, and a future shift towards Alt DA solutions like Celestia is likely to further weaken the profitability of the Ethereum mainnet. To address this issue, he suggested that in the short term, the mainnet could be supported by official L2 or rental mechanisms, while in the long term, new demands such as the tokenization of real assets are needed to enhance the overall utilization of L1/L2.He emphasized that the Ethereum community has advantages in coordination, but should decisively abandon unrelated projects and concentrate resources on breakthroughs at the application layer to cope with competitive pressures from L2 and other data availability solutions.

ChainCatcher news, the ETH/BTC exchange rate has reached its lowest level in nearly five years, with some investors even calling ETH a "completely dead" investment. Nic Carter, a partner at Castle Island Ventures, believes that "ETH is dying by its own hand," as L2 is too greedy, leading to a decline in Ethereum's trading activity, user growth, and fees/revenue. Ethereum can be seen as a practical network, but it is "absolutely not" an investment.

ChainCatcher news, Ethereum founder Vitalik Buterin published a long article titled "A simple L2 security and finalization roadmap," which outlines three core directions for optimizing Ethereum L2 security and finality:Expand data capacity: Increase the Blob space to 6 through the Pectra upgrade, and expand it to 72 (or gradually increase to 12-24) in the upcoming Fusaka upgrade at the end of the year, to meet the L2 transaction throughput demands;Implement a hybrid proof system for rapid finality: Use a 2/3 multi-signature mechanism (optimistic proof + ZK proof + TEE trusted hardware proof). If ZK and TEE verify simultaneously, finality is immediate; if only one is verified, it requires a 7-day optimistic challenge period. The security committee can urgently upgrade the proof logic but is subject to a 30-day delay, balancing immediate finality with attack resistance;Build a unified ZK proof aggregation layer: Standardize the proof aggregation protocol across the ecosystem, allowing multiple applications to share the cost of a single proof (e.g., 500,000 Gas), significantly reducing ZK verification overhead and promoting the adoption of L2, privacy protocols, and other scenarios. The goal of this roadmap is to achieve L2 cross-chain bridging finality within 1 hour and reduce costs through short-term hybrid verification mechanisms, while gradually eliminating TEE reliance with a long-term goal of full ZK implementation, ultimately establishing an efficient, secure, and trustless L2 ecosystem.

ChainCatcher message, Solana co-founder Anatoly Yakovenko responded to a user's point that "there's no reason to build L1, L2 can be faster, cheaper, and safer" by stating, "there's no reason to build L2, L1 can be faster, cheaper, and safer. They won't slow down due to the slow movement of the L1 data availability stack, nor do they have to compromise security through complex fraud proofs and upgraded multi-signatures."

ChainCatcher news, according to official sources, the Ethereum Layer2 network Lisk has announced that it has opened the eligibility query for the airdrop. Users can check their eligibility for the first season LSK rewards by entering their wallet address.

ChainCatcher news, Corn co-founder zak.eth posted on social media that Ethereum is facing the issue of value flowing to layer two networks (L2). He pointed out that currently, layer two networks are extracting significant fees, MEV, and liquidity, while Ethereum stakers are hardly benefiting.Data shows that Base generated about $2.5 million in fees last month, but paid less than $11,000 to Ethereum; Optimism earns about $321 from L2 fees for every $1 paid to Ethereum.zak.eth suggested several ways to improve this situation:L2 sequencers stake ETH, with a portion of L2 tokens deposited into the ETH treasury;L2 returns a portion of transaction fees and MEV to Ethereum stakers;ETH becomes the default settlement asset for cross-Rollup transactions;Ethereum validators expand security to L2 through re-staking.He believes that Ethereum needs to enforce this value capture now, or it may become an outdated security layer.

ChainCatcher news, Celo announced that the mainnet activation date for its transition to Ethereum L2 is March 26, 2025, at 11:00, with a hard fork block height of 31057000. After the upgrade, Celo L2 will reduce the block time from 5 seconds to just 1 second. Celo's complete history and block height remain unchanged, allowing users to look up past transactions.Previous news, Coinbase's announcement of not supporting the Celo blockchain migration has caused dissatisfaction in the community.

ChainCatcher news, Sony's Layer2 network Soneium has distributed two types of OG NFTs to early users: the Soneium OG Badge (requiring at least 45 transactions) and the Soneium Premium OG Badge (requiring bridging 1 ETH or 2500 USDC or 70000 ASTR to the network), which can now be queried through block explorers like Blockscout.On-chain data shows that the total number of holding addresses for the two OG NFTs is 426992.
