Syncing Strategies Guide

Proper blockchain synchronization is crucial for maintaining node reliability and data accuracy. This guide covers various syncing strategies and their implementation.

Sync Types Overview

• Full synchronization
• Fast sync
• Light sync
• Snap sync
• Archive node considerations

Implementation Examples

// Check sync status
const checkSyncStatus = async () => {
	const syncStatus = await web3.eth.isSyncing();
	if (!syncStatus) {
		// Node is synced
		return { synced: true };
	}
	return {
		synced: false,
		currentBlock: syncStatus.currentBlock,
		highestBlock: syncStatus.highestBlock,
		progress: (syncStatus.currentBlock / syncStatus.highestBlock) * 100,
	};
};

// Monitor sync progress
const monitorSync = async (callback, interval = 10000) => {
	return setInterval(async () => {
		const status = await checkSyncStatus();
		callback(status);
	}, interval);
};

Best Practices

1. Choose appropriate sync type for your needs
2. Monitor sync progress
3. Handle network interruptions
4. Implement fallback nodes
5. Consider storage requirements
