Glamsterdam (Ethereum 2026) bring ePBS and block-level access lists

Ethereum dey prepare Glamsterdam upgrade for H1 2026, na hin hard fork after Pectra and Fusaka. Traders suppose focus on di shift wey dey happen for Ethereum Layer 1 block building and ordering rules, no just dey follow another L2 scaling story. Key changes: - Enshrined Proposer-Builder Separation (ePBS, EIP-7732): e move proposer/builder market mechanics on-chain. Builders go cryptographically commit to blocks and validators go select di highest bid without seeing contents upfront. Di aim na make block production more auditable under consensus. - Block-Level Access Lists (BALs, EIP-7928): e improve execution parallelism by making storage access visible at block level. Roadmap dey target gas limits up to ~100M initially, ~200M when ePBS full operational, with aim toward ~10,000 TPS. - Gas repricing package: di article project say fees fit drop by up to ~78% (but real user impact depend on how workloads map to di new execution model). Wetin traders suppose watch: - MEV no go disappear. ePBS fit change MEV dynamics and fit cause builder concentration to rise because private order-flow advantages. E also bring implementation complexity and “free option” risks (builders wey bid but withhold payloads). - Market impact likely indirect. Compared to Dencun wey get more immediate blob-fee story, Glamsterdam benefits dey framed as longer-term infrastructure legibility, execution efficiency, and predictability. Bottom line for ETH traders: Glamsterdam na structural upgrade to Ethereum base-layer block market. Upside na clearer, rule-based block production and performance targets; risk na MEV-driven centralization and execution/implementation edge-case surprises.
