Proposal: [CONSTITUTIONAL] AIP: ArbOS Version 50 Dia
Vote: For
Rationale: We are supporting ArbOS 50 Dia because it is a straightforward but critical upgrade that keeps Arbitrum aligned with Ethereum’s Fusaka fork. The package of bug fixes and cryptographic improvements strengthens protocol security, while the new instrumentation for multi-gas tracking prepares the network for more flexible fee models ahead. Overall, we see this upgrade as low-risk, necessary, and positioning Arbitrum for continued growth.
