zk-rollup

According to official news, ZKsync announced plans to stop supporting ZKsync Lite (i.e., ZKsync 1.0) in 2026 ------ the first ZK-rollup launched on Ethereum. Everything is normal for now, and no immediate action is required; ZKsync Lite will continue to operate as usual. Funds remain secure, and withdrawals to L1 will continue to be supported throughout the deprecation process.ZKsync will announce a detailed deprecation plan within the next year and will soon provide specific details, timelines, and migration guidance.

ChainCatcher message, according to the Web3 asset data platform RootData X tracking data, in the past 7 days, the Layer 2 ZK-Rollup protocol Loopring has been the project with the most unfollows from top figures on X (Twitter). The new influential figures on X who unfollowed this project include DeFi analyst Ignas (@DefiIgnas) and crypto industry KOL Enheng (@enheng456).

According to ChainCatcher news, the CEO of Loopring has decided to step down at the end of August 2025 after more than three years in office to spend more time with his family, according to official news from Loopring. In addition, he reflected on Loopring's efforts and challenges in implementing Ethereum scaling with ZK-Rollup, building the Loopring DeFi ecosystem, and developing smart wallets, and stated that he will continue to pay attention to Loopring's development as a member of the community.

ChainCatcher message, according to the Web3 asset data platform RootData X tracking data, in the past 7 days, the decentralized ZK-Rollup StarkNet has been the project with the most unfollows by top figures on X (Twitter). The new influential figures on X who unfollowed this project include Blue Fox (@lanhubiji) and Sleeping in the Rain (@0xSleepinRain).

ChainCatcher news, according to Cointelegraph, the Ethereum ZK-Rollup scaling solution Starknet has announced that it has entered the "Stage 1" decentralization phase. According to the framework proposed by Vitalik Buterin in 2022, this phase means that the network has established a security council and a validity proof system, significantly reducing external interference.Starknet added that this framework is the "gold standard on-chain tool for analyzing Ethereum scaling solutions," and stated that this phase has been achieved through transformations such as the creation of a security council and the avoidance of censorship mechanisms. StarkWare CEO Eli Ben-Sasson stated that the next step will be to advance towards the "Stage 2" goal of complete decentralization, achieving a network fully governed by the community. According to L2beat, currently only three small Layer 2 projects have reached this stage.

ChainCatcher news, Scroll's official post on X states that it has upgraded to meet Stage 1 standards of Zk-Rollup through the Euclid upgrade. The Euclid upgrade introduces a permissionless sequencer model, ensuring that the network remains active even if the sequencer fails.In addition, Scroll has established a diverse security council consisting of 12 members (with 75% voting approval, including 7 independent members) to provide security guarantees, while users can safely exit before the upgrade. In the future, Scroll plans to advance to Stage 2 through multi-proof systems and Zk+TEE technology.

ChainCatcher news, Scroll co-founder Haichen Shen announced on platform X that the Scroll Euclid upgrade proposal has been voted through. According to the plan, this upgrade will include the following core content:Network milestone: Scroll will upgrade to Stage-1 ZK Rollup in two weeks;Performance improvement: Network throughput exceeds 2000 TPS, with a single transaction fee of less than 1 cent;Technical upgrade: Upgrade to zkVM Prover validator OpenVM;Protocol compatibility: Support for EIP-7702 (account abstraction extension) and RIP-7212 (precompiled contract optimization), and migration to MPT (Merkle Patricia Tree) data structure, further enhancing multi-chain compatibility.

ChainCatcher message, Scroll announced on platform X that it is expected to upgrade to Stage 1 ZK-Rollup in April this year. This stage will support forced transactions, permissionless transaction submissions, complete zkEVM proofs, and will also establish a security committee composed of industry experts.

ChainCatcher message, Polygon Zero team member Daniel Lubarov posted on X: "Plonky3 can now process over 2 million Poseidon2 hashes per second. The recent acceleration is mainly related to memory: avoiding copies, skipping zeroing, merging some FFT steps to keep content in cache, etc."In response, Vitalik Buterin stated: "2 million hash/s = 62 MB/s of Merkling is enough to completely re-hash the theoretically maximum size Ethereum consensus state within a single slot, now please execute blake3 or sha256."Polygon co-founder Sandeep expressed gratitude for Vitalik's praise of Polygon's ZK contributions and stated that they will continue to work hard.

ChainCatcher news, the Web3 industry research and analysis platform Web3Caff Research recently released an in-depth report on the L2 public chain Scroll. Web3Caff Research researcher ssr.eth pointed out in the report that in January 2021, Ethereum co-founder Vitalik Buterin stated that with the advancement of zk-SNARK technology, zk-Rollup would prevail among all Layer2 solutions. As a member of the zk-Rollup sector, Scroll is collaborating with the PSE team, supported by the Ethereum Foundation, to develop zkEVM. Although the PSE team has recently shifted its focus to zkVM, Scroll maintains its unique orthodoxy and is exploring new technologies such as zero-knowledge proofs and hardware acceleration, aiming to launch a more secure, efficient, and highly scalable zk-Rollup network.In addition, Scroll introduced EIP-4844 data blobs on April 29, 2024, to achieve Layer1 data availability. The emergence of EIP-4844 significantly optimizes Layer2 solutions and effectively alleviates data availability issues. The report further indicates that with the launch of the Scroll mainnet, its ecosystem is continuously improving, and community incentive activities and hackathons are attracting more and more users and developers.Despite the steady increase in its TVL and active address count, whether Scroll can stand out among numerous competitors remains a key concern for the community. For example, the disadvantages and risks faced by Scroll include issues of technological maturity and user acceptance; zk-Rollup technology is still in the validation phase, has a long development time, and hardware acceleration technology is still under testing. In terms of developer support and ecosystem building, the number of Scroll users and transaction volume still needs to grow. Challenges in cross-chain interoperability and ecosystem integration also increase the resistance to its comprehensive application, while the choice between zkVM and zkEVM will determine the future development direction.

ChainCatcher message, Taiko has now integrated with the OKX Web3 wallet. Users can perform cross-chain transactions, asset swaps, and claim test coins between Taiko and Ethereum assets using the OKX Web3 wallet. Taiko is a decentralized Ethereum-equivalent ZK-EVM and general ZK-Rollup, designed to allow developers and users of dApps developed on Ethereum L1 to use Taiko without any changes.It is reported that the OKX Web3 wallet is a one-stop Web3 gateway, now supporting over 95 public chains, with a unified app, plugin, and web interface. It covers five major areas: wallet, DEX, DeFi, NFT marketplace, and DApp exploration, and has launched a trading market for Bitcoin inscriptions and runes.
