Internet reports that the core infrastructure pledged by STRK has been deployed to the Starknet main network. The Validator tool is now in use, and users who hold at least 20000 STRK tokens and run a full node can become a Validator; the UI and DApp for Delegator will be launched when it is officially released tomorrow. Any user holding a STRK can participate in the pledge by entrusting a token to the Validator.
