Bedrock Explainer (Optimism’s latest update)

The OP Stack, Optimism's open-source software for deploying onchain products, uses a protocol upgrade process meant to keep the platform from changing against the interests of businesses building on it. Upgrades are drafted by OP Labs or other core contributors and reviewed by the Developer Advisory Board, then face a 7-day veto period in which tokenholders, chains, apps, and end-users can override the board's decision. Vetoed proposals enter an appeals and discussion phase and can be resubmitted. The article states that no single entity, including OP Labs or the Foundation, can unilaterally dictate the OP Stack's future.
