The Snapshot page shows that the Lido community is voting on the "Design and Implementation Path of Dual Governance" proposal, which will end on April 26.
If the proposal is passed, the dual governance research team will proceed with technical implementation. The dual governance mechanism (DG) is an iteration of protocol governance that gives StETH holders the following two rights: dynamic, user-scalable time locks for DAO decisions; a rage quit mechanism that takes into account the details of Ethereum withdrawal work. The approximate timeline is to deploy the testnet around the third quarter, and the mainnet may be deployed in late third quarter or fourth quarter. The specific time may change depending on security checks and testnet results.
