Hi! I got your point. So, when you add a new block this means you're creating a new coin. When you go to chain.js line 58, you'll see:
`const generateNextBlock = (txns) => {
const prevBlock = getLatestBlock(),
prevMerkleRoot = prevBlock.blockHeader.merkleRoot;
nextIndex = prevBlock.index + 1,
nextTime = moment().unix(),
nextMerkleRoot = CryptoJS.SHA256(1, prevMerkleRoot, nextTime).toString();
const blockHeader = new BlockHeader(1, prevMerkleRoot, nextMerkleRoot, nextTime);
const newBlock = new Block(blockHeader, nextIndex, txns);
blockchain.push(newBlock);
storeBlock(newBlock);
return newBlock;
};`
In this block, you are passing 4 parameters { 1, prevMerkleRoot, nextMerkleRoot, nextTime } you can also add more parameters like the name of sender and recipient. This information is stored in a hash which we consider a coin which you can modify based on your needs.

I get it now... But can I use this code on production server... To create a coin and allow miners to mine transactions...
I mean is this code secure to start my own coin creation like Bitcoin?
from blockchain.
Unfortunately not, this repo is for learning purposes. There are many things you can do to improve the code:
-
Confirmations: Each miner sends a message with a block. You can create a confirmation system to ensure the integrity of the data.
-
Transactions/data: You could implement transactions or data objects to address double-spending, transaction validation, and coinbase transactions.
-
levelDB: Once the P2P is initialized, you can create a script to retrieve and write all the blocks into the LevelDB database, validate them, and clean the database as needed.

Okay thanks...
If I include all this, will the code be ready for productions...?

yes
