According to BlockBeats, on July 10, StarkWare CEO Eli Ben-Sasson said at EthCC that StarkWare has submitted the Starknet Improvement Protocol (SNIP) to enable network staking. If approved by the community, staking may soon be launched on the testnet, with plans to release the mainnet in the fourth quarter of 2024.
If the proposal is passed, users can delegate to stakers, or become stakers themselves. There will be a 21-day time lock period before funds can be withdrawn.
