According to official news, Starknet launched the first phase of the staking plan on the mainnet. Anyone who holds STRK in their wallet can stake their tokens on Starknet as a validator or delegator, but in the first phase, validators stake at least 20,000 STRK and need to run a full node to prepare for future staking phases, which will require further responsibility and contribution to network maintenance and security.
In addition, Starknet reminds the community that neither StarkWare nor the Starknet Foundation will participate in staking activities at present, so they will not be eligible for any staking rewards. In addition, all locked tokens are currently not eligible for staking.
