区块时间戳指南

// 获取区块时间戳
const getBlockTimestamp = async (blockNumber) => {
	const block = await web3.eth.getBlock(blockNumber);
	return block.timestamp;
};

// 计算平均区块时间
const getAverageBlockTime = async (blockCount = 100) => {
	const latestBlock = await web3.eth.getBlockNumber();
	const oldBlock = await web3.eth.getBlock(latestBlock - blockCount);
	const newBlock = await web3.eth.getBlock(latestBlock);

	return (newBlock.timestamp - oldBlock.timestamp) / blockCount;
};
