rollup

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Ethereum co-founder Vitalik Buterin commented that "the original vision of Layer 2 as the primary scaling engine is no longer applicable," several L2 builders responded, generally agreeing that Rollup needs to move beyond the positioning of "a cheaper Ethereum," but there are disagreements on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.

The Bitcoin ZK-rollup project Citrea, backed by Founders Fund and Galaxy Ventures, has officially launched its mainnet, introducing DeFi lending, structured products, and the native USD stablecoin ctUSD, which uses BTC as collateral, aiming to bring "idle Bitcoin" into a complete DeFi and payment system.Citrea stated that the active DeFi liquidity at the initial stage of the mainnet launch is expected to reach $50 million. ctUSD is issued by MoonPay, pegged 1:1 to cash and short-term U.S. Treasury bonds, and is not a cross-chain asset but is natively issued on Citrea to reduce bridging risks and avoid liquidity fragmentation. The project has also sparked controversy: as block subsidies decline, should Bitcoin miner fee income be supported through non-payment uses like DeFi and stablecoins? Supporters argue that this is a sustainable source of demand, while opponents emphasize that Bitcoin block space should focus on simple, censorship-resistant payments.It is noteworthy that during the Citrea testnet phase, data availability usage once accounted for nearly 10% of Bitcoin's monthly data bandwidth, indicating that Rollup could have a substantial impact on Bitcoin's block space.

Vitalik Buterin stated that he is "significantly more inclined to support native rollups" compared to the past. Vitalik recalled that a major reason for opposing native rollups previously was that their precompiled solutions had to choose between ZK mode or Optimistic mode, and at that time, ZK-EVM was not mature. L2 often chose the latter, which involved "fast withdrawals but self-proving risks" versus "relying on Ethereum's security but needing to wait 2-7 days for withdrawals," thereby weakening Ethereum's composability and promoting the prevalence of multi-signature bridges and other solutions.Vitalik pointed out that the situation is changing: Ethereum's timeline for fully adopting ZK at the L1 level is gradually aligning with the realistic progress of introducing native rollup precompiles, and the aforementioned core obstacles are expected to be eliminated. He also mentioned that the community is increasingly viewing "synchronous composability" as one of the core values of L2 and is exploring the combination of rollup-based solutions with low-latency pre-confirmation mechanisms.In addition, Vitalik emphasized that the design of native rollup precompiles should not be rushed in its implementation. He expressed a hope that in the future, there would be a property such that if developers build a rollup that is "EVM plus a small amount of extended functionality," they could directly reuse the EVM part of the native rollup precompiles and only introduce a custom proof system for the new features, connecting the two in a standardized way.

The Rollup founder Andy posted on X: "After the initial token volatility digestion, Lighter's open interest (OI) is likely to drop by more than 20%, and trading volume may decline by over 30%.This is not a bull market, but a sideways, bearish market environment, which overall does not look optimistic. Nevertheless, if LIT's fully diluted valuation (FDV) is around $2 billion, I would still choose to buy."

ChainCatcher news, GOAT Network announced that its ecosystem token $GOATED will be launched on Binance Alpha on September 27.Before the TGE, users can check their eligibility and the amount for the airdrop through the OKX Wallet Checker page: http://web3.okx.com/ul/tBf5D9 After the TGE, users can continue to check and claim through the official GOAT airdrop page, and view FAQs: https://airdrops.goat.networkAs the first native ZK Rollup in the Bitcoin ecosystem to achieve real-time proof, GOAT Network has launched its Alpha mainnet, built on three key technologies: zkVM, BitVM2, and decentralized sequencers. It adopts a transaction fee model priced in BTC and combines a multi-asset PoS consensus, returning on-chain transaction revenue to nodes and stakers in the form of Bitcoin, fundamentally achieving a BTCFi revenue model that is bridge-free, natively secure, and economically sustainable.
