Technical Architecture
Core Components
Freecoin's architecture consists of three primary layers:
| Layer | Function | Technologies Used |
|---|---|---|
| Network | Peer-to-peer communication | libP2P, TCP/IP |
| Consensus | Transaction validation | Proof-of-Work, SHA-256 |
| Storage | Blockchain recording | LevelDB, Merkle Trees |
Implementation Details
Memory Management
- Custom allocators for transaction processing
- Smart pointers for resource safety
Network Layer
- Asynchronous I/O with Boost.ASIO
- Message serialization using Protocol Buffers
Security Features
- Hierarchical Deterministic (HD) wallets
- Multi-signature transaction support
Practical Implementation
Setting Up the Daemon
#include <freecoin/daemon.h>
int main(int argc, char* argv[]) {
DaemonConfig config;
config.loadFromFile("freecoin.cfg");
BitcoinDaemon daemon(config);
return daemon.run();
}Transaction Processing Workflow
- Receive transaction via P2P network
- Validate inputs/outputs
- Add to memory pool
- Include in next block
- Propagate through network
