2. Ethereum's "Glamsterdam" upgrade targeted for 2026, expected to reduce MEV exploitation

BlockBeats News reported on December 21st, "Ethereum developers have begun full-scale planning for the upcoming "Glamsterdam" upgrade after successfully conducting the Fusaka upgrade recently and reducing node costs. The goal is to launch in 2026. The name "Glamsterdam" is a combination of two simultaneous upgrades at Ethereum's core layers. The execution layer (where transaction rules and smart contracts reside) will undergo the Amsterdam upgrade, while the consensus layer (involving coordinating validators and finalizing blocks) will undergo the Gloas upgrade. The key of this upgrade is the proposer-builder separation (ePBS) and block-level Access Control List, which can reduce manipulation and abuse opportunities related to Maximum Extractable Value (MEV)."

3. Ethereum Foundation: Development focus shifts to security; plans to implement 128-bit security standards next year

PANews reported on December 21st that, "According to Cryptoslate, the Ethereum Foundation recently informed developers that it will shift its focus from pursuing speed to ensuring security, and plans to fully implement the 128-bit security standard by 2026. The Foundation warned that without formally verified reliability, attackers could rewrite the state, making high speed a serious vulnerability. The Foundation believes that while zkEVM has made significant performance progress over the past year, some solutions rely on unverified mathematical assumptions, theoretically posing a risk of on-chain state forgery. Therefore, the next phase of work will focus on strengthening formal verification, attack resistance, and fundamental cryptographic security."
