      description: >
        Identify the specific Solana validator assigned to produce blocks for
        the current or future slot.

        This consensus coordination API returns the validator identity (public
        key) that has been

        scheduled as the leader for a particular slot in the blockchain.
        Essential for network

        monitoring tools, validator performance analysis, block production
        tracking, and applications

        that need to understand the current leader schedule. The slot leader
        information is determined

        by Solana's proof-of-stake leader selection algorithm based on stake
        weight and randomness.
