# 🚀 Rust Blockchain Prototype
A simple blockchain prototype implemented in Rust. This project demonstrates **block
linking, cryptographic hashing (SHA-256), and basic chain validation**.
## 📌 Features
✅ Implements **SHA-256 hashing** for block security.
✅ Dynamically adds new **blocks with transactions**.
✅ Validates **blockchain integrity** to detect tampering.
✅ Rust’s **safe memory management** and high performance.
## ⚡ Installation & Setup
### 🔹 1. Clone the Repository
```sh
git clone https://github.com/afmontoya/rust-blockchain.git
cd rust-blockchain
2. Install Rust (if not installed)
curl --proto '=https' --tlsv1.2 -sSf https://sh.rustup.rs | sh
Verify installation:
rustc --version
cargo --version
3. Run the Blockchain
cargo run
How It Works
1 Each block contains:
Index: Block position in the chain.
Timestamp: When it was created.
Transaction Data: Example transactions (e.g., "Alice pays Bob 10 BTC").
Previous Hash: Links it to the previous block.
Hash: SHA-256 cryptographic hash of the block.
2️⃣New blocks are added dynamically, and the blockchain checks its integrity.
3️⃣ Example Output:
Block {
index: 0,
timestamp: 1738304591,
data: "Genesis Block",
prev_hash: "0",
hash: "84c70fe872b086a794dd802f657442b11f6d861678093955b941444c9b2790bb",
}
Block {
index: 1,
timestamp: 1738304591,
data: "Transaction: Alice pays Bob 10 BTC",
prev_hash: "84c70fe872b086a794dd802f657442b11f6d861678093955b941444c9b2790bb",
hash: "980cdeb08292cf65515e291d9946b01303fcad317e659e85902228f97eb93563",
}
Is blockchain valid? true
🔥 Planned Features (Future Improvements)
🚀 Proof of Work (Mining): Implementing difficulty-based mining.
🚀 Transaction System: Add real sender/receiver transactions.
🚀 Networking: Make it peer-to-peer (P2P) for decentralized nodes.
🚀 REST API: Build an HTTP API to interact with the blockchain.
🚀 Database Integration: Persist blockchain to a database (PostgreSQL).
