Arbitrum’s BoLD protocol is a major 2025 upgrade that makes the network more decentralized and secure by allowing anyone to participate in fraud-proof challenges, preventing delay attacks and ensuring withdrawals finalize within a predictable 7–13 days.

In 2025, Layer-2s like Optimism and Arbitrum have focused a lot on lowering fees and improving UX. Both have made progress on faster finality, better cross-chain bridges, and smoother onboarding for users and developers.

There’s also more adoption of shared sequencing, account abstraction, and better fraud-proof systems, which makes transactions cheaper and more secure while staying aligned with Ethereum.
