Best Practices for Block Management

// Reliable block fetching with retry mechanism
const fetchBlockWithRetry = async (blockNumber, maxRetries = 3) => {
	let retries = 0;
	while (retries < maxRetries) {
		try {
			const block = await web3.eth.getBlock(blockNumber);
			if (block) return block;
			throw new Error('Block not found');
		} catch (error) {
			retries++;
			if (retries === maxRetries) throw error;
			await new Promise((resolve) => setTimeout(resolve, 1000 * retries));
		}
	}
};

// Safe event handling with error boundaries
const createBlockListener = (callback) => {
	return web3.eth
		.subscribe('newBlockHeaders')
		.on('data', async (blockHeader) => {
			try {
				await callback(blockHeader);
			} catch (error) {
				console.error('Block processing error:', error);
				// Implement your error handling strategy
			}
		})
		.on('error', (error) => {
			console.error('Subscription error:', error);
			// Implement your reconnection strategy
		});
};
