Odaily Planet Daily News According to official news, Starknet has launched the first phase of its staking program on the mainnet. Anyone holding STRK in their wallet can stake their tokens on Starknet as a validator or delegator. However, in the first phase, validators must stake at least 20,000 STRK and need to run a full node to prepare for future staking phases, which will require taking on further responsibilities and contributing to the maintenance and security of the network.
