### To get started
```powershell
git clone https://github.com/j0fiN/rust-blockchain
cd rust-blockchain
cargo run
```
Your terminal should output this after execution.
```bash
[
    Block {
        prevhash: "",
        transaction: Transaction {
            amount: 100.0,
            payer: PublicKey([212, 228, 66, 151, 84, 100, 15, 69, 176, 15, 174, 89, 213, 77, 1, 197, 165, 14, 211, 66, 26, 195, 82, 173, 80, 62, 245, 2, 238, 119, 27, 111]),

### To develop it as an add-on to your application

| Code([main.rs](https://github.com/j0fiN/rust-blockchain/blob/main/src/main.rs))  | Doc  |
|---|---|
| ```chain::Chain::new()```  | Builds the blockchain with genesis block append by default.  |
| ```wallet::Wallet::new()```  | builds the node with digital signature components.  |
| ```satoshi.create_transaction(1200., notildore.pub_key)```  | Builds the transaction object and signs it and returns back trnsaction, signature and nonce.  |
| ```notildore.verify_and_add(transaction, satoshi.pub_key, sig, nonce, true, &mut blockchain)``` | transaction verification is done along with block append |

### Testing
```bash
cargo test
```
