Hi Miguel,

Many thanks for taking the time to answer my question, I will look to see if I can do as you say, I was just not sure if using a class function if it would be as simple as the last line of the code that I have updated below:

class Block {
    constructor(index, timestamp, transactions, reference, data, precedingHash = " ") {
 this.index = index;
 this.timestamp = Date.now();
 this.reference = uuidv4();
 this.transactions = Transaction;
 this.data = data;
 this.precedingHash = precedingHash;
 this.hash = this.computeHash();
 this.nonce = 0;
    }

    computeHash() {
 return SHA256(
 this.index +
 this.precedingHash +
 this.timestamp +
 this.reference +
            JSON.stringify(this.data) +
            JSON.stringify(this.transactions) +
 this.nonce
        ).toString();
    }

    mineBlock(difficulty) {
 while (
 this.hash.substring(0, difficulty) !== Array(difficulty + 1).join("0")
        ) {
 this.nonce++;
 this.hash = this.computeHash();
        }
        console.log("BLOCK MINED:" + this.hash);
    }
}

module.exports = Block;

or alternatively 

export default Block;

I will follow your suggestion and also attempt the above examples to see if I can achieve creating them as JSW and will update with findings.

Many thanks again,
