ChainCatcher message, Ethereum co-founder Vitalik Buterin stated that Layer 2 and sharding are often described as two opposing strategies for blockchain scalability in public discussions. However, when you delve into the underlying technology, a puzzle emerges: the actual scaling methods are completely the same. Both have some form of data sharding, both have fraud proofs or ZK-SNARK proofs, and both have methods to solve cross {rollup, shard} communication. The main difference lies in who is responsible for building and updating these components, and how much autonomy they possess.A Layer 2-centric ecosystem technically realizes sharding very effectively, but it is a sharding that can create its own rules. This is very powerful and can inspire a great deal of creativity and independent innovation. However, it also presents key challenges, especially in terms of coordination. For a Layer 2-centric ecosystem like Ethereum to succeed, it needs to understand these challenges and address them head-on to gain as many advantages as possible from a Layer 1-centric ecosystem while getting as close as possible to having the best features of both.

ChainCatcher news, according to the Shanghai Cyberspace Administration, a city-wide meeting on the management and coordination mechanism for blockchain development was held in Shanghai, focusing on the coordinated promotion of the blockchain industry, technology, and ecological planning layout.

ChainCatcher news, Galaxy's Vice President of Research Christine Kim published a summary of the 120th Ethereum Core Developers Consensus (ACDE) conference call, where developers discussed and coordinated changes to the Ethereum Consensus Layer (CL). This week, developers discussed CL specification version 1.4.0-beta.3, the launch conditions for Devnet-10, and blob delay analysis conducted by software developer Gajinder Singh, who maintains the Lodestar and EthereumJS clients.A new CL code specification for the Cancun/Deneb (Dencun) upgrade was released, referred to as "The Summoning," officially tagged as version 1.4.0-beta.3 in the CL GitHub repository, including the following two major changes: mainnet KZG configuration and new gossip rules.Regarding Devnet-10, changes in CL specification version 1.4.0-beta.3 will be tested on Devnet-10. There are some obstacles to the launch of Devnet-10, waiting for the client teams to release new software. Once ready, it is hoped that Devnet-10 will be launched at some point on October 20 (as of now, it has not been launched).Representatives from the Prysm and Lighthouse client teams indicated that they would release updated versions of their software before October 20. Regarding blob delay analysis, based on Gajinder Singh's experiments on Devnet-9, the more blobs received by validators, the significantly greater the block delay. Ryan encouraged another CL team to attempt to reproduce Singh's experiment on Devnet-9 to see if they could achieve similar values and results.

ChainCatcher news, the reState Foundation recently held an online dialogue where Ethereum co-founder Vitalik and Isha Foundation founder, Indian mystic Sadhguru discussed the intersection of technology and human consciousness.Vitalik believes that the core of blockchain technology is "coordination and interaction" between people. He said, "The purpose of (blockchain) is to help different groups of people come together, enabling them to trust each other more and collaborate over greater distances on many different types of projects." In his view, the gap between the speed of technological development and the speed of human moral and consciousness development is widening, with the latter being left behind.Vitalik is convinced that emerging technologies actually make it easier for people to recognize complex identities and connect with each other on common ground. While emerging technologies may not solve all users' problems, the protocols and disagreements in the field have the potential to lead to "realizing cooperation" and learning opportunities. He stated, "I think these are the ideas that many people I know in the Ethereum and related communities genuinely care about." (source link)

Chain Catcher News, Zhou Xiaochuan, Vice Chairman of the Boao Forum for Asia, pointed out on September 8 at the "2022 Second China (Beijing) Digital Finance Forum" that the digital renminbi is one of the modern public financial infrastructures and represents a significant upgrade of the central bank's payment system in terms of technology, organizational structure, and business model. Through this upgrade, it will achieve the overall coordination and integration of the national payment market, break down payment barriers, enhance user experience, and provide important foundational support for the development of digital finance."Many central banks around the world have begun to develop central bank digital currencies, and China has always been at the forefront. The DC/EP digital renminbi pilot project has achieved rich practical results, with application scenarios continuously expanding and broad prospects," Zhou Xiaochuan noted. Compared to developed countries like the US and Europe, which focus on cross-border payments for digital currencies, the digital renminbi emphasizes the retail payment segment.Zhou Xiaochuan stated, "It is clear that retail payment is an important foundation for effective cross-border payments. Imagine if two countries do not have efficient and secure digital currency retail payment arrangements, it would be difficult to achieve cross-border connectivity." At the same time, Zhou Xiaochuan also mentioned that cross-border payment and settlement of central bank digital currencies require coordination and cooperation between countries in terms of foreign exchange management policies and financial infrastructure.
