Currently the Optimism Foundation is running the sole sequencer because we don't have the fault challenges running yet. However, there are already many verifiers watching us to make sure this power is not abused. We are working hard at decentralization.
- Release Bedrock, enabling a multi-client architecture (done, June 6th 2023).
- Support (directly or indirectly) the creation of alternative Optimism clients (see op-erigon).
- Ship the multi-client proof contracts.
- Either renounce the power to upgrade the contracts further, or transfer it to the most trusted address in Ethereum.
