According to ChainCatcher, Ethereum Layer 2 solution Optimism tweeted that its governance organization Token House has approved the Optimism mainnet Bedrock upgrade through voting. This is not only the first on-chain vote conducted by Collective using the new voting page, but also the first proposal for a protocol upgrade.
It is reported that the standard upgrade process is to first conduct a Regolith hard fork on Optimism Goerli, and after the audit is repaired, conduct a 2-week test on the test network. Only after the test network stability standard is met, the Optimism Foundation will announce the upgrade date, at least 3 weeks after the release date. The upgrade will be triggered at a specific time, not a block height. (Source link)
