Node Integration Guide
Overview
- Status: ✅ Complete

JSON-RPC API
(port 8545)
axionaxNode Struct
pub struct axionaxNode {
config: NodeConfig,
network: Arc>,
state: Arc,
stats: Arc>,
rpc_handle: Option,
sync_handle: Option>,
} Node configuration, presets, and statistics available.
Basic Node Setup (Rust API)
use node::{axionaxNode, NodeConfig};
#[tokio::main]
async fn main() -> anyhow::Result<()> {
let mut config = NodeConfig::dev();
config.state_path = "/tmp/axionax-node".to_string();
config.rpc_addr = "127.0.0.1:8545".parse()?;
let mut node = axionaxNode::new(config).await?;
node.start().await?;
Ok(())
}Publishing Blocks/Transactions
// Publish block
node.state().store_block(&block)?;
node.publish_block(&block).await?;
// Publish transaction
node.publish_transaction(&tx).await?;
Querying Node State
let stats = node.stats().await;
printf!("Blocks stored: {}", stats.blocks_stored);
printf!("Peers connected: {}", node.peer_count().await);
let height = node.state().get_chain_height()?;
let latest_block = node.state().get_latest_block()?;
RPC Example
# Get block via RPC
curl -X POST http://127.0.0.1:8545 \
-H 'Content-Type: application/json' \
-d '{"jsonrpc":"2.0","method":"eth_getBlockByNumber","params":["latest",false],"id":1}'
Performance & Resource Usage
- Block Processing: ~200 μs per block
- Transaction Processing: ~40 μs per tx
- RPC Requests: ~5,000 req/s (single core)
- P2P Messages: ~10,000 msg/s (libp2p)
Error Handling
All errors returned as JSON-RPC error objects (error code, message, id).
{
"jsonrpc": "2.0",
"error": {
"code": -32001,
"message": "Block not found"
},
"id": 1
}Future Enhancements
- Full event-driven sync
- Mempool and advanced validation
- Peer reputation, bandwidth management
- Prometheus metrics and monitoring
Security Considerations
- RPC binds localhost by default
- libp2p Noise protocol encryption
- Strict hex validation
- Production rate limiting: TODO
