Let’s Create a Cryptocurrency in Rust: How I created the LyronCoin CryptoCurrency

1. Introduction to LyronCoin

Creating and launching a Crypto currency is a complicated process that requires not only technical knowledge but also financial and regulatory knowledge. This article serves as a high-level overview of the process. But none of the code here should be considered production ready.

Understanding Cryptocurrency

At its core, a cryptocurrency is a digital or virtual form of money that uses cryptography for secure financial transactions. Cryptocurrencies leverage blockchain technology to gain decentralization, transparency, and immutability. Unlike traditional currencies, they are not controlled by any central authority, offering a new way of thinking about money and value transfer.

Features of LyronCoin

LyronCoin is not just another addition to the multitude of digital currencies; it is designed with unique features that address some of the common challenges faced by existing cryptocurrencies:

  • Enhanced Security: Incorporating advanced cryptographic techniques to secure transactions and wallets.
  • Eco-Friendly Mining: A proof-of-stake model that reduces the environmental impact compared to traditional proof-of-work systems.
  • Smart Contract Functionality: Enabling complex agreements and automated transactions that are self-executing and self-enforcing.
  • Scalability: Focused on high transaction throughput and low latency to accommodate a growing user base.
  • User-Friendly: Emphasizing ease-of-use for both developers and end-users to foster widespread adoption.

Why Rust?

Rust is a multi-paradigm programming language focused on performance and safety, particularly safe concurrency. It’s known for its ability to produce highly reliable and efficient software that’s less prone to the bugs that can plague systems-level programming. The choice of Rust for developing LyronCoin brings several advantages:

  • Memory Safety: Rust’s ownership model guarantees memory safety, preventing common bugs and security vulnerabilities.
  • Concurrency: Rust makes concurrent programming easier and safer, which is a boon for a system that relies on networked nodes.
  • Performance: With performance comparable to C and C++, Rust ensures that LyronCoin can handle intensive operations like transaction processing and cryptographic computations quickly.
  • Rich Type System and Tooling: Rust provides powerful features like zero-cost abstractions and guarantees about code behavior, which help in building robust software.

Setting Up the Rust Development Environment

Before diving into the creation of LyronCoin, you’ll need to set up your Rust development environment. Follow these steps to get started:

  1. Install Rust: Visit the official Rust website and follow the instructions to install rustup, the Rust toolchain installer.
  2. Configure Cargo: Cargo is Rust’s build system and package manager. During the installation, it will be automatically configured, but you can customize it further by editing ~/.cargo/config.
  3. Install Dependencies: LyronCoin may require additional dependencies, such as cryptographic libraries. Install them using cargo or your system’s package manager.
  4. Choose an IDE: While you can use any text editor, an Integrated Development Environment (IDE) like Visual Studio Code, IntelliJ Rust, or Atom, with Rust support, can enhance your productivity.
  5. Testing Your Setup: Create and run a “Hello, world!” program to ensure everything is working correctly:
fn main() {     println!("Hello, world!"); }
cargo run

With your Rust environment ready, you are all set to embark on the development of LyronCoin.

2. Blockchain Basics for LyronCoin

In this section, we will delve into the fundamental concepts of a blockchain that are crucial for building LyronCoin, a robust and secure cryptocurrency. We will explore the nature of blocks, the role of hashing in blockchain technology, and the concept of immutability. Additionally, we will provide Rust code examples to lay the groundwork for your basic blockchain structure.

What is a Blockchain?

A blockchain is a distributed database that maintains a continuously growing list of records, called blocks, which are linked and secured using cryptography. Each block typically contains a cryptographic hash of the previous block, a timestamp, and transaction data. This design makes a blockchain resistant to data modification because once recorded, the data in any given block cannot be altered retroactively without the alteration of all subsequent blocks.

The Anatomy of a Block

In the context of LyronCoin, a block contains some essential elements:

  • Block Header: Metadata about the block, including the version, previous block hash, and timestamp.
  • Transaction Counter: The number of transactions included in the block.
  • Transactions: A list of transactions that the block contains.

Hashing and Its Importance

Hashing is a process that takes an input (or ‘message’) and returns a fixed-size string of bytes. The output is typically a ‘digest’ that uniquely represents the input data. In a blockchain, hashing is used to secure the blocks and create a chain of custody. If even a single bit of a transaction is altered, the hash will change drastically, signaling a discrepancy in the data.

Immutability in Blockchain

Immutability refers to the blockchain’s inability to be altered once a block has been added to the chain. This is fundamental to the trust model of blockchain, as it ensures that all transactions are final and unchangeable.

Building a Basic Blockchain Structure in Rust

Below is a simple Rust code example that demonstrates the creation of a basic blockchain structure. This includes defining a block and a blockchain, hashing, and adding new blocks to the chain.

use sha2::{Sha256, Digest};
use std::fmt::Write;

// A struct for the Block
#[derive(Debug)]
struct Block {
timestamp: i64,
data: String,
previous_hash: String,
hash: String,
}
// Implementing the Block
impl Block {
fn new(timestamp: i64, data: String, previous_hash: String) -> Self {
let mut block = Block {
timestamp,
data,
previous_hash,
hash: String::new(),
};
block.hash = Block::calculate_hash(&block);
block
}
fn calculate_hash(block: &Block) -> String {
let mut hasher = Sha256::new();
hasher.update(block.timestamp.to_string().as_bytes());
hasher.update(&block.data.as_bytes());
hasher.update(&block.previous_hash.as_bytes());
let hash = hasher.finalize();
let mut hash_str = String::new();
for byte in hash {
write!(&mut hash_str, "{:02x}", byte).expect("Unable to write");
}
hash_str
}
}
// A struct for the Blockchain
#[derive(Debug)]
struct Blockchain {
chain: Vec<Block>,
}
// Implementing the Blockchain
impl Blockchain {
fn new() -> Self {
let genesis_block = Block::new(0, "Genesis Block".to_owned(), String::new());
Blockchain {
chain: vec![genesis_block],
}
}
fn add_block(&mut self, data: String) {
let previous_hash = self.chain.last().unwrap().hash.clone();
let new_block = Block::new(Self::current_timestamp(), data, previous_hash);
self.chain.push(new_block);
}
fn current_timestamp() -> i64 {
// Use appropriate method to get the current timestamp
// Here we simply return a placeholder value
1_617_439_785
}
}
fn main() {
let mut lyroncoin = Blockchain::new();
lyroncoin.add_block("Block 1 Data".to_owned());
lyroncoin.add_block("Block 2 Data".to_owned());
println!("{:#?}", lyroncoin);
}

In the provided code, we create a new Block struct with the necessary fields. We then define a Blockchain struct that will hold our chain of blocks. With the add_block method, we can create new blocks and link them to the chain, ensuring they are immutable once added.

3. Designing and Implementing Transactions for LyronCoin

Transactions are the heart of any cryptocurrency. They are the means by which users exchange value, and they play a crucial role in maintaining the integrity and state of the blockchain.

Understanding Transactions

A transaction in a cryptocurrency network typically consists of the following components:

  • Input: References to previous transactions’ outputs.
  • Output: Specifies new ownership of the transferred LyronCoin and how much they own.
  • Amount: The quantity of LyronCoin to transfer.
  • Signature: A cryptographic signature that proves the ownership of the funds and the right to transfer them.

Creating a Transaction

In LyronCoin, a transaction must be created whenever a user wishes to transfer coins. This involves specifying the amount to be transferred and the recipient’s address. Here’s how you might define a transaction struct in Rust:

struct Transaction {
sender: String,
recipient: String,
amount: f32,
signature: String,
}

Signing a Transaction

Signing a transaction is how a user proves they have the right to spend the coins. This is done using their private key. For simplicity, let’s use an external crate like secp256k1 for cryptographic operations.

First, add secp256k1 to your Cargo.toml dependencies:

[dependencies]
secp256k1 = "0.20.1"

Then, implement the signing in Rust:

use secp256k1::{Secp256k1, Message, SecretKey};

impl Transaction {
// Assume `self` has the sender, recipient, and amount fields populated.
fn sign(&mut self, secret_key: &SecretKey) {
let context = Secp256k1::new();
let message = self.create_message();
let signature = context.sign(&Message::from_slice(&message).unwrap(), secret_key);

self.signature = signature.to_string();
}
fn create_message(&self) -> Vec<u8> {
let mut bytes = Vec::new();
bytes.extend(self.sender.as_bytes());
bytes.extend(self.recipient.as_bytes());
bytes.extend(&self.amount.to_le_bytes());
bytes
}
}

Verifying a Transaction

Verification is the process of ensuring that the transaction is valid and the signature is correct. To verify a transaction, you need the public key corresponding to the sender’s private key.

use secp256k1::{PublicKey, Signature};

impl Transaction {
// Verify that the signature is correct
fn verify(&self, public_key: &PublicKey) -> bool {
let context = Secp256k1::new();
let message = self.create_message();
let signature = Signature::from_str(&self.signature).unwrap();

context.verify(&Message::from_slice(&message).unwrap(), &signature, public_key).is_ok()
}
}

Integral to Cryptocurrency’s Functionality

The process of creating, signing, and verifying transactions ensures that:

  • Only the rightful owner can spend their LyronCoin.
  • The recipient can verify the legitimacy of the transaction.
  • Once a transaction is written to the blockchain, it cannot be altered or denied, thus preventing fraud.

By carefully designing the transaction structure and related processes, we ensure that LyronCoin operates securely and as intended, building trust in the network.

4. Setting Up a Peer-to-Peer Network for LyronCoin

A peer-to-peer (P2P) network is essential for cryptocurrencies to operate in a decentralized manner. It allows nodes to communicate directly with each other without the need for a central server. In this section, we’ll outline the setup of a P2P network for LyronCoin, including Rust code snippets for node communication, network synchronization, and the propagation of transactions and blocks.

Node Communication

In LyronCoin, nodes must communicate with each other to exchange transaction and block information. We’ll use a TCP-based server-client model for our P2P network.

First, add the tokio crate to your Cargo.toml to handle asynchronous operations:

[dependencies]
tokio = { version = "1.0", features = ["full"] }

Here’s a simple example of how you might establish a TCP connection in Rust using tokio:

use tokio::net::TcpListener;
use tokio::io::{AsyncReadExt, AsyncWriteExt};

#[tokio::main]
async fn main() {
let listener = TcpListener::bind("127.0.0.1:7878").await.unwrap();
loop {
let (mut socket, _) = listener.accept().await.unwrap();
tokio::spawn(async move {
let mut buf = vec![0; 1024];
// In a loop, read data from the socket and write the data back.
loop {
let n = socket.read(&mut buf).await.unwrap();
if n == 0 { break; }
socket.write_all(&buf[0..n]).await.unwrap();
}
});
}
}

Network Synchronization

Network synchronization ensures that all nodes have the same blockchain data. This is done by broadcasting the latest block to all nodes, which then verify and add it to their local blockchain copy.

To synchronize the network, you might have a function like this:

async fn synchronize(&self) {
// Request the latest block from peers
for peer in &self.peers {
let mut stream = TcpStream::connect(peer).await.unwrap();
stream.write_all(b"get_latest_block").await.unwrap();

let mut buffer = [0; 1024];
let n = stream.read(&mut buffer).await.unwrap();
let latest_block = deserialize_block(&buffer[..n]);

// Verify and add the block to the local blockchain
if self.blockchain.verify_and_add_block(latest_block) {
println!("Block added to the blockchain!");
}
}
}

Propagating Transactions and Blocks

When a new transaction or block is created, it must be propagated to all nodes in the network. Here’s a simple way to broadcast a new block:

async fn broadcast_new_block(&self, block: Block) {
let serialized_block = serialize_block(&block);

for peer in &self.peers {
let mut stream = TcpStream::connect(peer).await.unwrap();
stream.write_all(&serialized_block).await.unwrap();
}
}

LyronCoin nodes can now communicate, synchronize their blockchains, and propagate new transactions and blocks.

5. Mining Process and Proof-of-Work in LyronCoin

Mining is a crucial component of many cryptocurrencies. It involves validating transactions, creating new blocks, and maintaining the blockchain’s integrity. In this section, we’ll dive into the mining mechanism for LyronCoin, the role of miners, and the mining rewards system, with Rust code examples to illustrate these concepts.

Understanding Mining

Mining in the context of cryptocurrency is the process of performing complex computations to discover a new block, which is added to the blockchain. This process requires computational effort and is designed to be difficult to ensure network security.

Proof-of-Work (PoW)

Proof-of-Work is a consensus algorithm used by LyronCoin. It requires miners to solve a cryptographic puzzle to create a new block. The first miner to solve the puzzle gets to add the next block to the blockchain and is rewarded with LyronCoin.

The Role of Miners

Miners use their computational power to:

  • Validate transactions
  • Assemble transactions into a block
  • Solve the cryptographic puzzle (Proof-of-Work)

Mining Rewards System

Miners are incentivized by:

  • Block Reward: A fixed amount of LyronCoin awarded for discovering a new block.
  • Transaction Fees: Fees associated with the transactions included in the new block.

Rust Code Examples

Below is a simplified version of how mining might be implemented in Rust.

Defining a Block

First, define a struct for your block:

#[derive(Serialize, Deserialize, Debug, Clone)]
struct Block {
index: u64,
timestamp: u128,
transactions: Vec<Transaction>,
proof: u64,
previous_hash: String,
}

Mining a Block

Implement the mining function that includes the Proof-of-Work:

fn mine_block(last_proof: u64) -> u64 {
let mut proof = 0;
while !valid_proof(last_proof, proof) {
proof += 1;
}
proof
}

fn valid_proof(last_proof: u64, proof: u64) -> bool {
let guess = format!("{}{}", last_proof, proof);
let guess_hash = hash(&guess);
guess_hash.ends_with("0000") // This is the Proof-of-Work condition
}

Creating a New Block

Function to create and add a block to the blockchain after mining:

impl Blockchain {
fn create_new_block(&mut self, proof: u64, previous_hash: Option<String>) -> Block {
let previous_hash = match previous_hash {
Some(hash) => hash,
None => self.hash_last_block(),
};

let block = Block {
index: self.chain.len() as u64 + 1,
timestamp: current_timestamp(),
transactions: self.current_transactions.clone(),
proof,
previous_hash,
};
// Reset the current list of transactions
self.current_transactions.clear();
self.chain.push(block.clone());
block
}
}

Rewarding the Miner

After a block is mined, reward the miner:

fn reward_miner(&mut self, miner_address: &str) {
let reward_transaction = Transaction {
sender: "0".to_string(), // indicates a new coin creation
recipient: miner_address.to_string(),
amount: 1.0, // The mining reward
signature: "".to_string(), // Not required for the reward
};

self.current_transactions.push(reward_transaction);
}

Mining is a fundamental aspect of the LyronCoin network that facilitates transaction processing and network security.

6. Wallet Creation and Management for LyronCoin

A cryptocurrency wallet is a digital wallet used to manage cryptocurrencies. It is essential for storing private and public keys, interacting with various blockchains to enable users to send and receive digital currency, and monitor their balance.

Generating Keys

Key generation in cryptocurrency is typically done using cryptographic algorithms that ensure secure key pairs (public and private keys). Here is a basic Rust example using the secp256k1 library, which is commonly used in cryptocurrencies.

First, add the secp256k1 crate to your Cargo.toml:

[dependencies]
secp256k1 = "0.20.2"
rand = "0.8.4"

Next, generate a key pair:

extern crate secp256k1;
extern crate rand;

use secp256k1::{Secp256k1, SecretKey, PublicKey};
use rand::rngs::OsRng;
fn generate_keypair() -> (SecretKey, PublicKey) {
let secp = Secp256k1::new();
let mut rng = OsRng::new().expect("OsRng");
let (secret_key, public_key) = secp.generate_keypair(&mut rng);
(secret_key, public_key)
}

Managing Balances

In a cryptocurrency wallet, the balance is determined by scanning the blockchain for transactions that involve the wallet’s public key. For simplicity, let’s assume LyronCoin has a central ledger that we can query for the balance.

fn get_balance(public_key: &PublicKey) -> f64 {
// This function would interface with the LyronCoin ledger or blockchain
// to calculate the balance of the associated public key.
// For demonstration purposes, we'll return a dummy balance.
100.0
}

Securing Transactions

To secure transactions, wallets sign them with their private keys. This signature can then be verified by others using the public key.

Here’s how you might sign a transaction:

use secp256k1::{Message, Signature};
use sha2::{Sha256, Digest};

fn sign_transaction(transaction: &Transaction, secret_key: &SecretKey) -> Signature {
let secp = Secp256k1::new();
let message = Message::from_slice(&hash_transaction(transaction)).expect("32 bytes");
secp.sign(&message, secret_key)
}
fn hash_transaction(transaction: &Transaction) -> [u8; 32] {
let mut hasher = Sha256::new();
hasher.update(format!("{:?}", transaction));
let result = hasher.finalize();
let mut hash = [0u8; 32];
hash.copy_from_slice(&result);
hash
}

To verify the signature:

fn verify_transaction(transaction: &Transaction, signature: &Signature, public_key: &PublicKey) -> bool {
let secp = Secp256k1::new();
let message = Message::from_slice(&hash_transaction(transaction)).expect("32 bytes");
secp.verify(&message, signature, public_key).is_ok()
}

We have established a foundational framework for creating a wallet in LyronCoin, managing balances, and securing transactions. However, it is crucial to handle errors robustly and secure the secret keys adequately in a production environment. Additionally, the actual implementation would require interacting with LyronCoin’s blockchain to fetch balances and verify transactions, which would require more complex networking and storage logic.

7. Smart Contracts Integration in LyronCoin

Smart contracts are self-executing contracts with the terms of the agreement between buyer and seller being directly written into lines of code. They run on a blockchain and automatically enforce and execute the terms of a contract when predetermined conditions are met.

In the context of LyronCoin, smart contracts can add significant value by enabling automated transactions that are transparent, traceable, and irreversible, without the need for a trusted intermediary. These could range from simple fund transfers upon fulfillment of conditions, to more complex decentralized applications (dApps).

Here’s an overview of how basic smart contracts could be implemented in LyronCoin using Rust.

Smart Contract Basics

For our basic implementation, a smart contract will be a Rust struct with an associated function that acts when conditions are met.

First, let’s define a simple smart contract struct:

struct SmartContract {
owner: PublicKey,
payload: String,
// In a real-world scenario, `conditions` would be more complex and
// might include cryptographic proofs or references to external data.
conditions: Vec<String>,
executed: bool,
}

impl SmartContract {
// A new smart contract is created with its conditions and payload.
fn new(owner: PublicKey, payload: String, conditions: Vec<String>) -> Self {
SmartContract {
owner,
payload,
conditions,
executed: false,
}
}
// Function to evaluate and execute the contract.
fn execute(&mut self, current_conditions: &[String]) -> Result<(), &'static str> {
if self.executed {
return Err("Smart contract already executed");
}
if (self.conditions.iter().all(|condition| current_conditions.contains(condition))) {
// Execute the payload, which in a real scenario could be any predefined action.
println!("Executing smart contract: {}", self.payload);
self.executed = true;
Ok(())
} else {
Err("Conditions not satisfied")
}
}
}

Implementation Example

Here is how you might use this struct to create and execute a smart contract within LyronCoin:

// Assuming we have the necessary imports and context from previous sections...
fn main() {
// Owner's public key and conditions are provided.
let (secret_key, public_key) = generate_keypair();
let conditions = vec!["Condition1".to_string(), "Condition2".to_string()];
let mut contract = SmartContract::new(public_key, "Transfer 100 LyronCoin".to_string(), conditions);

// Current state of the world with conditions that might trigger the contract.
let current_conditions = vec!["Condition1".to_string(), "Condition2".to_string()];
match contract.execute(&current_conditions) {
Ok(_) => println!("Contract executed successfully"),
Err(e) => println!("Failed to execute contract: {}", e),
}
}

The Rust code examples provided here are simplified to illustrate the concept of smart contracts in LyronCoin. Real-world implementations would need to handle a broad range of conditions, include more complex execution logic, and ensure security through rigorous testing and auditing. Additionally, integrating these smart contracts with the LyronCoin blockchain would involve adding functionality for deploying, calling, and interacting with these contracts on the chain.

8. Testing and Security in the LyronCoin Blockchain

In the world of cryptocurrency, security is paramount. Even minor oversights can lead to significant vulnerabilities. Rust, with its focus on safety and concurrency, offers many features that can help in creating a secure blockchain. It’s crucial to leverage Rust’s strengths to ensure the LyronCoin blockchain is robust against attacks and operates reliably.

Testing Strategies in Rust

Rust provides a built-in test framework that you can use to write unit tests, integration tests, and documentation tests. Here are strategies for testing the different components of LyronCoin:

Unit Testing

Unit tests in Rust are written as functions annotated with #[test] and can be used to test individual modules of your code. For LyronCoin, you would write unit tests for functions handling transactions, block creation, hashing, and consensus algorithms.

Here’s an example of a unit test for a simple hashing function:

#[cfg(test)]
mod tests {
use super::*;

#[test]
fn test_hash_function() {
let data = "LyronCoin";
let hash = hash_data(data);
assert_eq!(hash, expected_hash_string);
}
}
fn hash_data(data: &str) -> String {
// Simplified hashing function for demonstration purposes
format!("{:x}", md5::compute(data))
}

Integration Testing

Integration tests are external to your library and use your code in the same way any other code would. This is where you test the interactions between different components of LyronCoin. For instance, you could test how well the transaction system interacts with the blockchain.

// tests/integration_test.rs

use lyroncoin;
#[test]
fn test_transaction_to_blockchain() {
let transaction = lyroncoin::Transaction::new(/* parameters */);
let mut blockchain = lyroncoin::Blockchain::new();
blockchain.add_transaction(transaction);
assert!(blockchain.validate_chain(), "The blockchain should be valid after adding a transaction.");
}

Property-Based Testing

Property-based tests are designed to test the properties of your code with many random inputs. This is useful for testing the LyronCoin blockchain, where you expect certain properties to hold true, such as the immutability of data within blocks.

use proptest::prelude::*;

proptest! {
#[test]
fn test_block_immutable(data in any::<String>()) {
let block = lyroncoin::Block::new(data.clone());
assert_eq!(block.data, data, "Block data should be immutable.");
}
}

Rust’s Safety Features and Network Security

Rust’s type system and ownership model enforce memory safety guarantees that eliminate certain classes of bugs at compile-time. For LyronCoin, these features mean that many potential security vulnerabilities can be caught early in the development process.

Borrow Checker

The borrow checker ensures that references do not outlive the data they point to and that one mutable reference or any number of immutable references to a resource can exist at a time. This prevents race conditions, which are critical in a concurrent environment like a blockchain network.

Pattern Matching

Pattern matching in Rust is exhaustive, which means all possible cases must be covered when handling an enumeration (enum). This can be used to ensure that all possible states of a transaction or block are considered, reducing the chances of unexpected behavior.

Fearless Concurrency

Rust’s ownership rules allow for safe concurrency without data races. This is crucial for LyronCoin’s peer-to-peer networking, where multiple threads may access shared resources.

By utilizing the safety features provided by Rust, the security and reliability of the LyronCoin blockchain can be significantly enhanced. Rust’s compile-time checks and pattern matching lead to more predictable and safer code, reducing the risk of vulnerabilities and errors. Thorough testing, including unit, integration, and property-based tests, ensures each component functions correctly independently and within the larger system, providing a strong foundation for a secure cryptocurrency network.

9. Deploying LyronCoin: Launching a Live Node and Network

Deploying a cryptocurrency like LyronCoin to a live environment is a significant step. It involves setting up a node, launching the network, and ensuring you have the right tools to monitor and maintain it. This tutorial will guide you through the process of taking LyronCoin from development to a live blockchain network.

Setting Up a Live Node

A node is an instance of the LyronCoin software that participates in the network. Each node stores a copy of the blockchain and contributes to the network’s functioning.

Requirements:

  • A server with sufficient resources (CPU, RAM, disk space, network bandwidth)
  • Latest stable version of Rust and Cargo
  • Latest version of LyronCoin software

Instructions:

Prepare the Server: Ensure your server is secure, updated, and has Rust installed. It’s recommended to use a Linux-based OS for better security and performance.

Install LyronCoin: Clone the LyronCoin repository from your version control system to the server.

git clone https://yourversioncontrol.com/lyroncoin.git cd lyroncoin

Compile the Node: Compile the LyronCoin node using Cargo.

cargo build --release

Configure the Node: Edit the lyroncoin.conf configuration file to set up network parameters, ports, and other operational settings.

Run the Node: Start the LyronCoin node. It will begin to sync with the existing blockchain (if joining an existing network) or await connections (if initiating a new network).

./target/release/lyroncoind

Launching the Network

If you’re starting a new LyronCoin blockchain, your node will be the first in the network. If you’re joining an existing network, your node will connect to peers.

New Network:

  • Initiate the Genesis Block: The first block in the blockchain is the genesis block and is hardcoded into your LyronCoin software.
  • Broadcast the Network: Share the node details with peers you want to join the network. They’ll need to configure their nodes to connect to yours.

Joining an Existing Network:

  • Discover Peers: Use a peer discovery mechanism to connect to existing nodes. This could be hardcoded peers, DNS seeds, or a peer exchange protocol.
