Layer 2 network Blast announced that it will cease operations due to the ongoing maintenance costs of the network exceeding the revenue generated by L2. The team believes there is no credible path to achieve economic sustainability.Blast advises all users to withdraw on-chain assets and balances in the Blast PWA to the Ethereum mainnet and plans to shorten the withdrawal waiting time to 24 hours. However, the team will first process the withdrawal of Lido assets held by Blast, which is expected to take about a week, during which the withdrawal function will be temporarily unavailable.Users can complete withdrawals through the regular Blast interface before October 26. After that, assets can still be withdrawn, but it will require direct interaction with the Blast Bridge contract on Ethereum L1. The team will announce specific operational instructions before the deadline.

The Rollup founder Andy commented on the MetaMask infrastructure security incident, stating that, according to sources, unless significant negative news arises, there will be a small-scale withdrawal of staked ETH. It is recommended to take proactive measures for all re-staked ETH positions that have exposure to Lido.Andy expressed hope for a positive outcome, but he believes it may be wiser for the protocol and investors to actively respond. He mentioned that the current situation seems to be under control, but based on his recent communications with multiple parties, no one is clear about what exactly has happened.

DogeOS, the application layer of Dogecoin, launched its public testnet on Wednesday, introducing EVM-compatible smart contracts to the Dogecoin network as a zero-knowledge rollup, with DOGE as the native token for transaction fees. The project aims to support applications such as trading, lending, stablecoins, prediction markets, and gaming, while settling state back to the Dogecoin network.DogeOS currently uses a trusted execution environment, validators, and a permissioned sequencer to ensure network security. Future proposed upgrades to Dogecoin Core will allow Dogecoin miners to directly verify their execution proofs. DogeOS CEO Jordan Jefferson stated that Dogecoin does not currently verify ZK proofs on its own, and bridging state transitions requires valid proofs as well as signatures from a majority of validators and TEE signers. He mentioned that the team is currently focused on the public testnet, allowing developers time to build and test applications, with the mainnet timeline to be announced upon reaching the next development milestone.DogeOS comes from the MyDoge wallet team, which announced a $6.9 million funding round led by Polychain Capital in May 2025. Two months later, the DogeOS team submitted a proposal for a Dogecoin Core upgrade to add native ZK proof verification for Dogecoin, but this upgrade has not yet been implemented. Timothy Stebbing, a director of the Dogecoin Foundation, expressed hope that DogeOS will serve as a springboard for a new wave of practical engineering.

The Rollup founder Andy posted that market rumors suggest the U.S. Securities and Exchange Commission (SEC) is preparing to launch the largest tokenization innovation exemption policy to date, which may allow tokenized securities to be traded solely through registered transfer agents, without the need for broker-dealer licenses, and without adhering to traditional trading platform or ATS-related rules. It is also reported that this could cover U.S. retail investors and overseas investors.Andy stated that if the above news is true, its potential impact would be significant. Tokenized funds could be issued and traded directly in the form of on-chain tokens, with transfer agents maintaining legal ownership records on-chain, while the underlying assets held by the fund, such as stocks and bonds, could also be further tokenized, thus forming an on-chain trading system of "fund tokens + underlying asset tokens."Andy later mentioned that a large fund has already received the SEC's "green light," but this has not yet been officially confirmed. He speculated that ARK, Fidelity, or BlackRock could be potential participants. If the policy is ultimately implemented, U.S. asset management firms may accelerate the issuance of native equity tokens to compete for around-the-clock liquidity and on-chain distribution channels, rather than waiting for third parties to mirror tokenize traditional securities. He further linked this potential policy change to the recent push by the Trump administration for regulatory openness in the crypto market, as well as the CFTC's efforts to bring perpetual contracts to the U.S. market, believing that the U.S. regulatory environment may be gradually opening the policy floodgates for on-chain finance.

According to The Rollup host Andy, his sources indicate that a large fund has received the SEC's "green light," possibly involving Fidelity, ARK Invest, or BlackRock, allowing fund shares to be tokenized and traded against underlying assets.Andy emphasized that this is still unverified information, and specific arrangements await confirmation from SEC Chairman Atkins.

GnosisDAO approved the transformation of the blockchain network Gnosis Chain from an independent Layer 1 network to a zero-knowledge proof Ethereum Economic Zone (EEZ) Rollup. The network will eliminate the independent validator set and instead have Ethereum validators complete transaction settlements.The proposal received support from 123,158 GNO, 115 against, and 151 abstentions, with voting involving 54 participants and a total participation of 123,425 GNO, exceeding the quorum threshold of 75,000 GNO. The upgrade is tentatively planned to start at the end of 2026 or the beginning of 2027, depending on the readiness of EEZ technology.After the upgrade, Gnosis Chain's native smart contracts can call Ethereum in the same transaction and use the returned results, while also accessing Ethereum mainnet assets and liquidity. Gnosis Chain will become the first deployed EEZ instance and will retain existing applications, balances, and xDAI fuel tokens.

Vitalik Buterin stated that he has compared the 2023 Ethereum roadmap with the current Strawmap, and while there is still a high degree of overlap in the overall direction, some priorities and technical paths have been clearly adjusted. This includes elevating the priority of quantum security, downplaying VDF and certain EVM improvements, and replacing old designs with unified binary trees, PBT, new state types, and other solutions.He pointed out that the most significant change in the current Strawmap is the emergence of several new topics not included in the 2023 roadmap, reflecting a shift in the focus of Ethereum's development. These new focal points include: stronger native privacy support, aggressive scaling in a post-quantum context, streamlined specifications for formal verification, Blob and Gas futures, native Rollup, and a more open design space around the future form of EVM.Vitalik also emphasized that Ethereum's scaling approach is shifting from "broadly scaling all activities" to "designing more easily scalable dedicated mechanisms for specific high-load scenarios," and views STARK proofs and AI-accelerated formal verification as important foundations for the protocol's future. Overall, this update indicates that the Ethereum roadmap is evolving towards quantum security, privacy-first, censorship resistance, high performance, and more simplified protocol design.

According to Shield's monitoring, the wallet address marked as the attacker of the Aztec Network Private Rollup Bridge has deposited 300 ETH into Tornado Cash again, worth approximately $572,000. So far, the attacker has transferred a total of 500 ETH to Tornado Cash.Previously, Aztec Network suffered a security attack in June 2026, resulting in a loss of approximately $2.165 million in crypto assets. This transfer of funds may further complicate the tracking of the stolen assets.

According to SlowMist's YuXian monitoring, Aztec is suspected to have been hacked again, with its Private Rollup Bridge 0x737...A2ba showing three suspicious transactions, totaling approximately $2.15 million, involving 1,158 ETH, 150,000 DAI, and 0.46963295 renBTC.

Syndicate Labs, Everclear, and ZERO Network announced the cessation of operations on the same day, highlighting the deep dilemmas in the blockchain infrastructure sector.Syndicate Labs, a startup supported by a16z and having raised over $27 million, announced its closure after five years of operation, stating that EVM Rollup is no longer the industry standard and the market has fundamentally shifted to custom chains. The cross-chain settlement protocol Everclear (formerly Connext) announced hours later that it would shut down its foundation and lab entities, despite having a monthly trading volume that once reached $500 million, it was unable to convert that volume into revenue, and the CLEAR token dropped about 40% on the same day. The gasless Ethereum Layer 2 ZERO Network built by the crypto wallet Zerion also announced its closure on the same day, with the team shifting focus to the development of Zerion wallet and API products, and users must bridge their funds out by July 31.The common dilemma faced by the three projects is that even with venture capital funding and operational products, it remains difficult to find a sustainable business model to withstand market deterioration.

According to The Block, Gnosis co-founder Friederike Ernst and Zisk founder Jordi Baylina jointly announced the "Ethereum Economic Zone" (EEZ) plan at the EthCC conference in Cannes on Sunday, which is co-funded by the Ethereum Foundation.The EEZ aims to create a framework for Rollups, allowing smart contracts on connected Rollups to perform synchronous composable calls with the Ethereum mainnet and other EEZ Rollups, with security guarantees equivalent to those directly deployed on Ethereum. The framework defaults to using ETH as the Gas token, eliminating the need for additional cross-chain bridge infrastructure. Ernst stated, "Ethereum does not have a scalability problem; it has a fragmentation problem. Every new L2 that goes live has its own liquidity pool and bridging, creating another isolated walled garden."Founding members of the EEZ alliance include the DeFi lending protocol Aave, block builders Titan and Beaver Build, the RWA platform Centrifuge, and the tokenized stock project xStocks. The project will operate as a Swiss non-profit organization, with all software released as open-source, aiming to minimize governance and ultimately achieve non-upgradability. Technical specifications and performance benchmarks are expected to be announced in the coming weeks.

According to The Block, Ethereum researchers demonstrated a proof of concept for "native Rollups" based on the execution client Ethrex, implementing EIP-8079 through the addition of an EXECUTE precompile, which directly replays and verifies Layer 2 block state changes on the Ethereum base layer.This solution does not rely on zero-knowledge proofs or fraud proofs, but instead is executed and confirmed by Ethereum itself to validate Rollup transaction validity. The related contracts are used to track Rollup state, bridge cross-layer messages, and verify withdrawals based on Merkle-Patricia proofs. Developers claim that native Rollups can simplify long-term maintenance of Layer 2, allowing them to directly inherit Ethereum's security and upgrade properties, and they are still in the exploration and proof of concept stage.

Uniswap founder Hayden Adams posted on the X platform, stating that the main issue with describing Rollups as "parasitic" is that these projects undertake a significant and costly engineering effort to scale Ethereum.In a Rollup-centric roadmap, this work is intentionally outsourced. If Ethereum wishes to be more independent, it needs to adopt a serious engineering-driven approach rather than treating every issue as a research problem.

According to Cointelegraph, after Ethereum co-founder Vitalik Buterin commented that "the original vision of Layer 2 as the primary scaling engine is no longer applicable," several L2 builders responded, generally agreeing that Rollup needs to move beyond the positioning of "a cheaper Ethereum," but there are disagreements on whether scaling should still be its core role.Optimism co-founder Karl Floersch welcomed the challenge of building a modular L2 stack that supports "full-spectrum decentralization," while acknowledging that there are still major obstacles such as long withdrawal periods, second-stage proofs not being production-ready, and insufficient cross-chain application tools. He supports the native Rollup precompiled solutions emphasized by Buterin.Steven Goldfeder, co-founder of Arbitrum developer Offchain Labs, took a firmer stance, arguing that although the Rollup model has evolved, scaling remains the core value of L2. He pointed out that Arbitrum was not built as "a service of Ethereum," but because Ethereum provides a highly secure and low-cost settlement layer, making large-scale Rollups possible. He warned that if Ethereum is seen as hostile to Rollups, institutions might choose to launch independent Layer 1 chains instead of deploying on Ethereum.Base head Jesse Pollak stated that scaling Ethereum L1 is "a victory for the entire ecosystem," agreeing that L2 cannot just be "a cheaper Ethereum." He mentioned that Base is differentiating itself through applications, account abstraction, and privacy features, and is working towards decentralization in the second stage.StarkWare CEO Eli Ben-Sasson hinted that some ZK-native L2s (like Starknet) believe they already fit the specialized role described by Buterin. The entire Ethereum ecosystem is facing a roadmap adjustment: the base layer aims to enhance its capabilities, while L2 is repositioning itself as a dedicated environment serving different technical needs.
