Block Gas Management Guide

Understanding and managing gas consumption at the block level is crucial for optimizing transaction costs and ensuring reliable operation of Ethereum applications.

Gas Fundamentals

• Block gas limits
• Gas price dynamics
• EIP-1559 fee mechanism
• Gas estimation strategies

Implementation Strategies

// Get block gas limit
const getBlockGasLimit = async () => {
	const block = await web3.eth.getBlock('latest');
	return block.gasLimit;
};

// Estimate optimal gas price
const getOptimalGasPrice = async () => {
	const blockCount = 10;
	const latest = await web3.eth.getBlockNumber();
	const blocks = await Promise.all([...Array(blockCount)].map((_, i) => web3.eth.getBlock(latest - i)));

	const gasPrices = blocks.map((block) => block.baseFeePerGas);
	return Math.floor(gasPrices.reduce((a, b) => a + b) / blockCount);
};

Optimization Techniques

1. Dynamic gas price adjustment
2. Transaction batching
3. Off-peak execution
4. Gas limit optimization
5. EIP-1559 fee strategies
