Zhixiong Pan: The reasons for the redesign include: 1) Aging of the beacon chain: the beacon chain specification was frozen five years ago, during which time technology and understanding have made great progress; 2) Deeper understanding of MEV: over the past five years, we have gained a deeper understanding of maximum extractable value (MEV) and developed mechanisms to mitigate its negative impact; 3) Breakthroughs in SNARK and ZKVM: zero-knowledge proof technology has made significant progress, with performance improvements of orders of magnitude, and the emergence of ZKVM has enabled non-cryptography experts to utilize these technologies; 4) Opportunity to clean up technical debt: the beacon chain has technical debt, and a redesign is an opportunity to clean up these debts. The planned roadmap for the consensus layer includes nine major projects, divided into three categories: 1) Block production: improving MEV handling, enhancing censorship resistance, introducing inclusion lists, implementing validator-proposer separation, and shortening slot times; 2) Staking: adjusting the issuance curve, reducing the minimum staking amount from 32 ETH to 1 ETH, and achieving single-slot finality; 3) Cryptography: real-time SNARK-ification of the consensus layer and the use of post-quantum secure cryptographic schemes. Challenges include: 1) Technical complexity: implementing real-time SNARK-ification and post-quantum cryptography requires overcoming significant technical hurdles, including changing the hash function, signature scheme, and state serialization; 2) Risk management: implementing multiple major changes at once increases systemic risk, requiring particularly careful testing and verification to ensure the network's security and stability; 3) Community consensus and coordination: broad community support and consensus are needed, as well as coordination among multiple client teams, including onboarding new teams and training them on new technologies; 4) Delay risk in the timeline: complex upgrades may lead to delays in the timeline, requiring flexibility and contingency plans; 5) Standardization and compatibility: due to the diversity of ZKVM, compatibility between different implementations must be ensured to avoid fragmentation, and a specific ZKVM should not be chosen at the consensus layer to reduce complexity; 6) Security and stability: while introducing new technologies, new vulnerabilities must be prevented to ensure the long-term security and sustainability of the Ethereum network; 7) Adoption and testing of new technologies: extensive and in-depth testing, potentially over years, is required to ensure the safe deployment of new technologies on the mainnet.
