ChainCatcher message, Ethereum co-founder Vitalik Buterin stated on social media: "In 2015, we didn't know about the existence of Rollups and Plasma. Data availability sampling had not yet been invented. We didn't know when SNARKs would be feasible. Basically, everything we knew about how to scale in a decentralized way was downstream research from 2015 to 2020."

ChainCatcher message, Ethereum co-founder Vitalik Buterin stated on social media that starting next year, he plans to only publicly mention (in blogs, speeches, etc.) L2 projects that are at stage 1+, and may give a brief grace period to some genuinely interesting new projects.Vitalik said: "Whether I have invested or not, or whether you are my friend, the project must reach stage 1, otherwise it will not be considered. Multiple ZK-rollup teams have told me they expect to reach stage 1 by the end of the year. I am very excited about this.Of course, we should not easily abandon training rounds until we have real confidence in the security of the proof system; doing so would be irresponsible. But stage 1 (75% of the council needs to cover the proof system, and 26%+ of the council members must come from outside the rollup team) is a very reasonable moderate milestone. The multi-signature wallet I am part of has not experienced a single activity failure in years, let alone a 26% failure rate. The era of rollups as glorified multi-signature wallets is coming to an end. The era of crypto trust is about to arrive."

ChainCatcher news, Galaxy Research stated in a report that the vast majority of Bitcoin rollups will be unsustainable. Due to transaction fees, Bitcoin rollups require millions of dollars annually to maintain.Galaxy wrote, "Each individual data publication transaction can occupy up to 400KB (0.4MB) of block space, effectively taking up 10% of an entire block." With multiple rollups expected, data is anticipated to be published every 6 to 8 blocks, which could quickly push the base layer fees to new highs and make small transactions too expensive. Given the competition for block space, only rollups that can generate the most fee revenue and pay block fees will be able to sustain operations.Galaxy estimates that in a low-fee environment, when the average transaction cost is 10 sat/VB, rollups will incur $460,000 in monthly fees to maintain Bitcoin's security. In a high-fee environment of 50 sat/VB, when Ordinals or tokens minted through Runes or the BRC-20 standard are frequently active, monthly costs could reach $2.3 million.

ChainCatcher news, according to News.bitcoin, Web3 developer Quicknode's Vice President of Products Josh Neuroth stated that ZK Rollups provide tangible benefits in transaction throughput and data confidentiality, making these L2 solutions more of a foundational technology rather than a fleeting trend. Furthermore, as the technology behind these L2 solutions matures, more projects are adopting them, and the Web3 space may witness lasting improvements in blockchain performance and user experience.Meanwhile, Neuroth expressed his agreement with Bitcoin extremist David Sorey's view that ZK Rollups are a missing piece in the Bitcoin network's scalability and privacy. He explained that ZK Rollups ultimately "help Bitcoin overcome its current limitations and compete with other blockchain networks that offer advanced features."

ChainCatcher news, Everclear (formerly known as Connext Network) is now integrated with the OKX Web3 wallet. Users can perform cross-chain transactions, exchanges, provide liquidity, and more through the OKX Web3 wallet on Everclear. Everclear is a communication protocol that supports fast, trustless communication between different blockchain networks and Rollups, enabling developers to build cross-chain applications on top of it, such as asset cross-chain bridges, cross-chain DeFi protocols, and more.It is reported that the OKX Web3 wallet is an industry-leading one-stop Web3 gateway, now supporting over 95 public chains, with a unified experience across app, extension, and web. It covers five major areas: wallets, DEX, DeFi, NFT markets, and DApp exploration, and has launched a trading market for Bitcoin inscriptions and runes, among others.

ChainCatcher news, according to Cointelegraph, the liquid staking derivatives (LSD) project Puffer Finance, built on the Ethereum restaking protocol Eigenlayer, recently announced a collaboration with the Ethereum Foundation to jointly develop Base Rollups. Base Rollups alleviate the burden on layer one blockchains by processing transactions off-chain. Puffer Finance's LSD technology allows Ethereum validators to reduce the required capital from 32 ETH to 1 ETH, while simultaneously earning yields in other DeFi protocols through liquid restaking tokens (nLRT).Currently, Puffer Finance's total locked value has exceeded $1.2 billion, having raised a total of $23.5 million in venture capital funding.Previously, the project completed a $18 million Series A funding round to launch the mainnet.

ChainCatcher news, OP Labs developer vex released the MVP (Minimum Viable Product) version of the OP Stack Rollup state transition component kona yesterday.Optimism co-founder Mark Tyneway commented on this, saying: "The OP Stack can be used for ZK Rollups faster than you might think."

ChainCatcher message, Ethereum co-founder Vitalik Buterin stated on social media that he personally believes that in 10 years all rollups will be ZK, and each slot will submit blocks with the final state root to L1. Achieving this goal requires a lot of infrastructure and prover optimizations, but this is clearly the ultimate goal.
