    Hi Raj,

    Bitcoin & Ethereum use the POW but Ethereum will soon move to POS.

    Hi,
    I am working on Project 2. I can set mapping movie names with movie ratings. I can set array, but can't put these together, please help.
    pragma solidity ^0.5.12;

    contract movieRatingByMovieName {

    struct movieDetails {
    string movieName;
    uint movieRating;
    }

    mapping (string => movieDetails) movieDetailsMapping;

    function addMovieDetails (uint _movieRating, string memory _movieName) public {
    movieDetailsMapping[_movieName].movieRating = _movieRating;
    }

    function getMovieDetailsRating (string memory _movieName) public view returns(string memory, uint) {
    return (_movieName,movieDetailsMapping[_movieName].movieRating);
    }

    }

    contract movieRating {

    string[] movieName;
    uint[] movieYear;

    function addMovie (string memory _movieName, uint _movieYear) public {
    movieName.push(_movieName);
    movieYear.push(_movieYear);
    }

    function getMovie(uint _index) public view returns(string memory, uint) {

    return (movieName[_index], movieYear[_index]);
    }
    }
